Anterior thigh pain after cementless total hip arthroplasty.

We compared the incidence of anterior thigh pain retrospectively following primary uncemented total hip replacement in 70 patients (78 hips) with osteoarthritis. In one group (38 hips), an Endoplus porous-coated, canal-filling prosthesis was inserted through an anterolateral approach. In the other group (40 hips), a Furlong hydroxyapatite-coated prosthesis was inserted through a posterior approach. The latter prosthesis has a relatively longer femoral stem and does not achieve diaphyseal press-fit contact. Three patients in the Furlong group had anterior thigh pain, which eventually resolved in two patients. In the Endoplus group, two patients developed anterior thigh pain; in both cases, there was an underlying cause, which had to be treated. Idiopathic anterior thigh pain is more common in non-canal-filling prostheses. When anterior thigh pain is noticed in canal-filling prosthesis, a search for and treatment of the cause will cure the pain. The hydroxyapatite coating did not prevent thigh pain in the Furlong group.

A method to estimate the depth of the sciatic nerve during subgluteal block by using thigh diameter as a guide.

BACKGROUND AND OBJECTIVE: The subgluteal approach is common for sciatic nerve block. Although the surface landmarks are clear, the depth of this nerve at this level is difficult to judge. The purpose of this study is to establish a method of estimating the sciatic nerve depth using the anteroposterior (AP) diameter of the thigh as a marker. METHODS: The study was undertaken in 2 phases. Phase 1 entailed review of 100 magnetic resonance images (MRIs) of the pelvis and proximal lower extremity of patients. Measurements were taken of the AP diameter of the thigh at the midpoint of the lesser trochanter and then compared with distances of the sciatic nerves from the skin of the posterior aspect of the thigh at the same level. Phase 2 involved enrolling 40 patients undergoing lower-extremity surgery for whom subgluteal sciatic nerve blocks were indicated. The AP diameters of the thighs were measured from the subgluteal groove to the inguinal groove with the patient in the supine position. Placing the patient in the lateral position, the subgluteal sciatic block was then performed by using a stimulating needle. The distances from the skin at which the sciatic nerves were actually found, as estimated by maximum motor response to stimulus, were noted. RESULTS: Phase 1 showed a mean AP diameter of 18.94 cm +/- 2.61 cm (mean +/- standard deviation [SD]), mean nerve depth of 6.51 cm +/- 1.46 cm (mean +/- SD), and a linear regression slope of 0.48. Phase 2 showed a mean AP diameter of 16.28 cm +/- 2.73 cm (mean +/- SD), a mean nerve depth of 6.99 cm +/- 1.39 cm (mean +/- SD), and a linear regression slope of 0.43. The thigh diameters differed (P < .001) between the groups, but there was no difference in the depth to the sciatic nerve between the 2 groups (P = .07). CONCLUSIONS: Comparing phase 1 and phase 2 datasets shows the slopes of linear regression lines are nearly parallel. The clinical data from phase 2 verify the anatomical data collected in phase 1 and show that the sciatic nerve depth to AP diameter ratio is 0.43 or the depth of the sciatic nerve is approximately 43% of thigh diameter if the patient is positioned in the lateral decubitus position.

Is thigh saphenectomy a necessary adjunct to high ligation and stab avulsion phlebectomy?

BACKGROUND: Controversy still exists as to whether the thigh saphenous vein should be stripped concomitant with high ligation and phlebectomy. METHOD: A total of 218 procedures were retrospectively grouped into three groups: group 1, 10 limbs with visible, duplex scan-confirmed varicose veins of the thigh saphenous vein; group 2, 13 saphenous veins with varices that were not clinically evident; group 3, 195 limbs with incompetent saphenous veins without thigh saphenous varices. RESULTS: Five limbs in group 1 were treated by high ligation, phlebectomy, and thigh saphenectomy. All did well. Five had high ligation and phlebectomy only. Two developed painful phlebitis, and two had residual varices in the saphenous vein. Group 2 and group 3 were treated by high ligation and phlebectomy. One group 2 limb developed saphenous phlebitis. Five limbs in group 3 developed recurrent veins that were removed in the office. CONCLUSION: Thigh saphenectomy is only required when there are visible, duplex scan-confirmed varices of the thigh saphenous itself, or when the procedure is performed for severely symptomatic patients or those with advanced stasis changes.

Use of thigh pressure cuffs to modulate simulated microgravity-induced changes in the skin measured with high-resolution B-scan ultrasound.

OBJECTIVE: The aim of the present study was to evaluate the fluid shift in a simulated microgravity experiment and to test the use of thigh cuffs to help alleviate the problem. METHODS: The change in skin thickness was assessed by a 20 MHz B-scan ultrasound device. This was performed on eight volunteers who underwent two successive 7-day periods of -6 degrees anti-orthostatic bed-rest, with or without the daytime use of thigh cuffs. The thigh cuffs were used to counteract the development of facial oedema. RESULTS: In the control group (without thigh cuffs), the results showed a steady increase in skin thickness of the combined dermis and hypodermis of the forehead and a reduction of the thickness of this tissue on the tibia. For the countermeasure group, although thigh cuffs were only employed during the daytime - being removed at night - their use reduced the amplitude and kinetics of the fluid shift, resulting in greater beneficial effects at the end of the day than early in the morning. CONCLUSION: These results of objective measurements of skin made using a non-invasive high frequency ultrasonography method confirm reports by cosmonauts of a reduction in facial oedema and a more 'comfortable' adaptation to microgravity by the use of thigh cuffs during space flight. This system is potentially promising for investigating fluid shifts in the skin and may prove useful in the evaluation of some oedematous skin diseases, as well as their therapy.

Age-related changes in fat deposition in mid-thigh muscle in women: relationships with metabolic cardiovascular disease risk factors.

OBJECTIVE: To determine if fat deposition within mid-thigh muscle, represented by low density lean tissue density, is associated with age, low physical fitness, hyperleptinemia, hyperinsulinemia and dyslipidemia in women. SUBJECTS: Seventy-two women aged 18-69y with a wide range of total body fat (10-55%) and maximal aerobic capacity (VO2max: 17-61 ml/kg(-1)/min(-1)). MEASUREMENTS: Mid-thigh muscle, mid-thigh fat, low density lean tissue, intra-abdominal adipose tissue (IAAT) and subcutaneous abdominal fat (by computed tomography, CT), fat mass (FM) and fat-free mass (FFM) (by dual energy x-ray absorptiometry, DEXA), plasma insulin and leptin (by radioimmunoassay, RIA) and lipoprotein lipid profiles (by enzymatic methods). RESULTS: VO2max declined with age (r=-0.59, P<0.0001) while IAAT and subcutaneous abdominal fat increased with age (r=0.68, r=0.57, r=0.63, P<0.0001). Mid-thigh low density lean tissue correlated with age (r=0.52), VO2max (r=-0.56), FFM (r=0.35), fat mass (r=0.68), IAAT (r=0.66) and subcutaneous abdominal fat (r=0.67, all P<0.005). Mid-thigh low density lean tissue also correlated with fasting plasma leptin, insulin, triacylglycerol (TG), total cholesterol (TC) and low-density-lipoprotein cholesterol (LDL-C) levels (r=0.44, 0.34, 0.41, 0.50, 0.53, respectively, all P<0.005), but not after controlling for body fat and age. Subcutaneous abdominal fat, IAAT, FFM and age were independent predictors of low density lean tissue (P<0.05). CONCLUSIONS: Mid-thigh low density lean tissue is directly related to age and adiposity. Furthermore, it appears that fat accretion in skeletal muscle adversely influences plasma insulin and lipoprotein metabolism in women, but not independently of total adiposity and age.

Relation of birth weight to lean and fat thigh tissue in young men.

BACKGROUND: Birth weight is positively associated with body mass index (BMI, kg/m2) in later life, but is inversely associated with cardiovascular risk. To understand this paradox, we examined the relationships between birth weight, adult BMI, and estimations of lean and fat tissue in young men. METHODS: From 192 applicants for military service (ages 17-22 y, mean BMI 23.2 kg/m2) with known birth weights we measured the circumference and anterior skinfold thickness at midthigh to estimate thigh muscle+bone area and subcutaneous fat area. Linear regression models including birth weight as the independent variable were adjusted for race and adult height. RESULTS: BMI was linearly associated with birth weight (standardized regression coefficient, [SRC]=+0.27; P=0.0004), as was the thigh muscle+bone area (SRC=+0.22; P=0.0029), but not the thigh subcutaneous fat area (SRC=+0.13; P=0.086). The BMI-birth weight association was reduced by 68% when the regression model was further adjusted for thigh muscle+bone area. Separate adjustment for thigh subcutaneous fat, however, reduced the BMI-birth weight association by only 30%. Waist circumference was also associated with birth weight (SRC=+0.24; P=0.0014), sagittal abdominal diameter was weakly associated (SRC=+0.17; P=0.028), but waist/thigh ratio and abdominal diameter index were not associated with birth weight. INTERPRETATION: The larger BMI associated with higher birth weight may reflect increments in lean tissue more than increments in fat. Birth weight's influence on lean tissue is observed in the thigh and, among fit young men, perhaps at the waist. Increased muscularity in young men may partly explain the cardiovascular benefit in middle age ascribed to higher birth weight.

Anterolateral thigh flap for abdominal wall reconstruction.

The free or pedicled anterolateral thigh flap was introduced for the reconstruction of large abdominal wall defects. This flap is superior to the tensor fasciae latae musculocutaneous flap in several respects. These include the wide, reliable skin territory (which can reach the level of the knee) and the long pedicle. Therefore, a pedicled anterolateral thigh flap with reliable blood circulation can easily be positioned above the umbilicus. In addition, the free anterolateral thigh flap has greater freedom of orientation and can be used to repair larger abdominal wall defects than can the tensor fasciae latae flap. Seven patients in whom abdominal wall defects had been reconstructed with pedicled or free anterolateral thigh flaps were reviewed. Their average age was 47.1 years (range, 21 to 74 years), and the average follow-up period was 10.7 months (range, 2 to 21 months). The size of the abdominal wall defects ranged from 12 x 12 cm to 18 x 24 cm, and the size of the transferred flap ranged from 10 x 20 cm to 20 x 20 cm. Three flaps were pedicled and four were free, of which three incorporated the tensor fasciae latae flap. All flaps survived completely, and no postoperative abdominal hernias developed. Despite some variations in vascular anatomy and technical difficulties in elevating the anterolateral thigh flap, the authors conclude that the pedicled or free anterolateral thigh flap is superior to the tensor fasciae latae flap for reconstruction of large abdominal wall defects.

Free anterolateral thigh flap for extremity reconstruction: clinical experience and functional assessment of donor site.

From August of 1995 through July of 1998, 38 free anterolateral thigh flaps were transferred to reconstruct soft-tissue defects. The overall success rate was 97 percent. Among 38 anterolateral thigh flaps, four were elevated as cutaneous flaps based on the septocutaneous perforators. The other 34 were harvested as myocutaneous flaps including a cuff of vastus lateralis muscle (15 to 40 cm3), either because of bulk requirements (33 cases) or because of the absence of a septocutaneous perforator (one case). However, vastus lateralis muscle is the largest compartment of the quadriceps, which is the prime extensor of the knee. Losing a portion of the vastus lateralis muscle may affect knee stability. Objective functional assessments of the donor sites were performed at least 6 months postoperatively in 20 patients who had a cuff of vastus lateralis muscle incorporated as part of the myocutaneous flap; assessments were made using a kinetic communicator machine. The isometric power test of the ratios of quadriceps muscle at 30 and 60 degrees of flexion between donor and normal thighs revealed no significant difference (p > 0.05). The isokinetic peak torque ratio of the quadriceps and hamstring muscles, including concentric and eccentric contraction tests, showed no significant difference (p > 0.05), except the concentric contraction test of the quadriceps muscle, which revealed mild weakness of the donor thigh (p < 0.05). In summary, the functional impairment of the donor thighs was minimal after free anterolateral thigh myocutaneous flap transfer.

Combined anterolateral thigh flap and vascularized fibula osteoseptocutaneous flap in reconstruction of extensive composite mandibular defects.

Extensive composite defects of the oromandibular area are usually created after the surgical treatment of T3 and T4 cancers, requiring complex reconstructive plastic surgical procedures. The preferred treatment method for this type of defect is reconstruction with two free flaps. The use of the vascularized fibula osteoseptocutaneous flap for the bone and inner lining defect is well known and accepted. Among the flaps that can be used for the outer lining and soft-tissue reconstruction, the two most commonly used have been the forearm flap and the rectus abdominis myocutaneous flap. However, these flaps have some disadvantages that restrict their use for this purpose. The forearm flap is usually too thin to cover the fibular bone and reconstruction plate, and the rectus abdominis myocutaneous flap can cause a subclinical reduction in abdominal strength. Both radial forearm and rectus abdominis myocutaneous flaps are difficult to harvest during tumor excision. Because of these drawbacks, over the past several years the authors have preferred to use the anterolateral thigh flap for outer face, neck, and submandibular region reconstructions. From October of 1998 to June of 2000, 22 extensive composite mandibular defect reconstructions using the free anterolateral thigh flap, combined with the vascularized free fibula osteoseptocutaneous flap, were performed at the Chang Gung Memorial Hospital. Complete flap survival was 90.9 percent (40 of 44 flaps). Complete loss was seen in an anterolateral thigh flap, which was then reconstructed with a pectoralis major myocutaneous pedicled flap (2.3 percent). There were five venous problems: three in osteoseptocutaneous free fibula flaps, the other two in anterolateral thigh flaps; all were revised immediately. However, the skin islands of two osteoseptocutaneous free fibula flaps and one anterolateral thigh flap developed partial necrosis (6.8 percent). The other complications were compartment syndrome in the leg in one patient, external carotid artery rupture in one patient, three donor-site infections in two patients, three neck wound infections, and one myocardial insufficiency; all were treated properly. Thirteen patients underwent revision procedures 6 months after the first operation. These procedures included debulking of the flap or revision of the mouth angle or both. Trismus or intraoral contraction was noted in none of these patients. In conclusion, the free anterolateral thigh flap combined with the vascularized fibula osteoseptocutaneous flap seems to be a good choice in the reconstruction of the extensive composite defects of the oromandibular region aesthetically and functionally.

Free anterolateral thigh adipofascial perforator flap.

The anterolateral thigh adipofascial flap is a vascularized flap prepared from the adipofascial layer of the anterolateral thigh region. It is a perforator flap based on septocutaneous or musculocutaneous perforators of the lateral circumflex femoral system. With methods similar to those used for the free anterolateral thigh flap, only the deep fascia of the anterolateral thigh and a 2-mm-thick to 3-mm-thick layer of subcutaneous fatty tissue above the fascia were harvested. In 11 cases, this flap (length, 5 to 11 cm; width, 4 to 8 cm) was used for successful reconstruction of extremity defects. Split-thickness skin grafts were used to immediately resurface the adipofascial flaps for eight patients, and delayed skin grafting was performed for the other three patients. The advantage of the anterolateral thigh adipofascial flap is its ability to provide vascularized, thin, pliable, gliding coverage. In addition, the donor-site defect can be closed directly. Other advantages of this flap, such as safe elevation, a long wide vascular pedicle, a large flap territory, and flow-through properties that allow simultaneous reconstruction of major-vessel and soft-tissue defects, are the same as for the conventional anterolateral thigh flap. The main disadvantage of this procedure is the need for a skin graft, with the possible complications of subsequent skin graft loss or hyperpigmentation.

Comparison of clinical and functional outcomes and hospital costs following pharyngoesophageal reconstruction with the anterolateral thigh free flap versus the jejunal flap.

BACKGROUND: Pharyngoesophageal defects are commonly reconstructed with free jejunal or fasciocutaneous flaps, with various outcomes, and a direct comparison is lacking. METHODS: Fifty-seven circumferential pharyngoesophageal reconstructions with an anterolateral thigh flap (n = 26 patients) performed by a single surgeon or jejunal flap (n = 31 patients) performed by six experienced surgeons between 1998 and 2004 were reviewed and outcomes were compared. RESULTS: Total flap loss occurred in one (4 percent) and two (6 percent) patients, fistula rates were 8 percent and 3 percent, and stricture rates were 15 percent and 19 percent in the anterolateral thigh and jejunal flap groups, respectively (p > 0.5). A completely oral diet was achieved in 95 percent and 65 percent, and fluent tracheoesophageal speech was achieved in 89 percent and 22 percent of patients with the anterolateral thigh and jejunal flaps, respectively (p < 0.01). The mean lengths of postoperative ventilator support, intensive care unit stay, and hospital stay were 1.0 +/- 0.2, 1.7 +/- 1.0, and 8.0 +/- 3.7 days for the anterolateral thigh flap group and 2.2 +/- 3.0, 3.0 +/- 3.2, and 12.6 +/- 7.9 days for the jejunal flap group (p < 0.001 for all), respectively. Mean hospital charges per patient were $8694 and $12,651 for the anterolateral thigh and jejunal flap groups, respectively (p = 0.02). CONCLUSIONS: With the limitations of comparing a single surgeon's results with those of multiple surgeons, the anterolateral thigh flap appears to offer better speech and swallowing functions and quicker recovery and to be more cost-effective than the jejunal flap for pharyngoesophageal reconstruction. The complication rates were similar.

The proximal pedicled anterolateral thigh flap for lower limb coverage.

Although primarily considered as a versatile free-flap donor site, the anterolateral thigh can also be a source of a local muscle perforator flap. This attribute has previously been rarely considered for lower limb coverage. This small series of 3 additional cases demonstrates the usefulness of a proximal pedicled anterolateral thigh flap for medial and lateral thigh wounds. This flap can also be part of a combined flap, in particular when transferred with the vastus lateralis muscle as a local chimeric flap. The peninsular version of the anterolateral thigh local flap avoids venous congestion and is very reliable. The orthograde pedicled anterolateral thigh muscle perforator flap should be considered as another useful alternative for any upper thigh wound if a flap is essential.

Use of fascia component of the anterolateral thigh flap for different reconstructive purposes.

The anterolateral thigh flap is commonly used for reconstruction of soft-tissue defects located at various sites of the body. This versatile flap offers many advantages to the reconstructive microsurgeons for the treatment of difficult defects. From 2000 to 2005, 70 anterolateral thigh flaps were transferred to reconstruct soft-tissue defects. We retrospectively reviewed these patients and found that the fascia lata component of the flap was used for different purposes in 19 patients. The fascia lata component of the flap was used for suspension of the flap in lip reconstruction in 12 patients, for reconstruction of dural defect in the scalp in 2 patients, for reconstruction of tendon defects in the forearm in 3 patients, and for reconstruction of fascia defect in the abdominal wall in the remaining 2. Complete loss of the flap was seen in an anterolateral thigh flap (5.2%) that was used for lower lip reconstruction. One flap necrosed partially (5.2%), and it was treated with surgical debridement and transposition of latissimus dorsi musculocutaneous flap. The objective of this study is to focus on the reliability of the fascial component of the anterolateral thigh flap. Although many authors have described other advantages of the anterolateral thigh flap extensively, this peculiarity has not been stressed adequately. Anterolateral thigh flap offers a thick and vascular fascial component with large amounts that can be used for different reconstructive purposes, and it should be taken into consideration as an important advantage of the flap, together with other well-known advantages.

Doppler ultrasound findings in reticular veins of the thigh subdermic lateral venous system and implications for sclerotherapy.

BACKGROUND: Treatment of varicose veins is directed towards eliminating sources of reflux causing venous hypertension in the superficial venous system. Doppler ultrasound is routinely used to localize sources of reflux prior to treatment of large varicose veins. OBJECTIVE: To assess the value of Doppler ultrasound in localizing reflux in subcutaneous reticular veins associated with groups of lateral thigh telangiectases. METHODS: Seven hundred patient records in which Doppler ultrasound was performed on thigh reticular veins were reviewed. Patients with reflux of the saphenofemoral junction, saphenopopliteal junction, or major saphenous system perforators were excluded. RESULTS: Audible reflux upon distal calf compression release was noted in thigh subcutaneous reticular veins of 618 out of 700 patients (88%). These incompetent reticular veins were associated with groups or webs of telangiectases and/or venulectases on the lateral thigh in almost all cases. Reflux was loudest just distal to the lateral femoral condyle. In 20 patients Doppler ultrasound was performed on a reticular vein while a telangiectasia associated with the reticular vein was injected with sclerosing solution. In 15 patients a clearly audible flow signal was heard in the reticular vein during injection. CONCLUSION: These findings indicate an association of telangiectatic veins with reticular veins on the thighs. Furthermore, this study underscores the value of Doppler in determining sources of reflux in smaller veins and implies that sclerotherapy of reticular veins is necessary for treatment of thigh telangiectatic webs.

Bilateral diabetic thigh muscle infarction.

A 19-year-old woman with insulin-dependent diabetes mellitus developed pain and tenderness in the medial aspect of the left thigh and calf, followed 1 week later by similar symptoms in the right leg. Technetium 99m pyrophosphate (PYP) radionuclide scans showed increased flow and uptake in the medial thigh muscles. Magnetic resonance imaging (MRI) of the thigh showed increased signal on proton density and T2-weighted images in the medial and lateral thigh compartments. High-resolution B-mode ultrasound showed hyperechoic changes in the anteromedial thigh muscles, with loss of normal myofascial interfaces, and a mixed appearance, bilaterally. Two months later, after the symptoms had begun to resolve, the images had improved. This case documents bilateral diabetic thigh infarction identified by abnormal technetium 99m PYP flow studies, MRI signal, and B-mode ultrasound imaging.

Insulin action in human thighs after one-legged immobilization.

Insulin action was assessed in thighs of five healthy young males who had one knee immobilized for 7 days by a splint. The splint was not worn in bed. Subjects also used crutches to prevent weight bearing of the immobilized leg. Immobilization decreased the activity of citrate synthase and 3-OH-acyl-CoA-dehydrogenase in the vastus lateralis muscle by 9 and 14%, respectively, and thigh volume by 5%. After 7 days of immobilization, a two-step euglycemic hyperinsulinemic clamp procedure combined with arterial and bilateral femoral venous catheterization was performed. Insulin action on glucose uptake and tyrosine release of the thighs at mean plasma insulin concentrations of 67 (clamp step I) and 447 microU/ml (clamp step II) was decreased by immobilization, whereas immobilization did not affect insulin action on thigh exchange of free fatty acids, glycerol, O2, or potassium. Before and during the clamp step I, lactate release was significantly higher in the immobilized than in the control thigh. Seven days of one-legged immobilization causes local decreased insulin action on thigh glucose uptake and net protein degradation.

The thigh may not be suitable as an injection site for patients self-injecting sumatriptan.

The objective of our study was to evaluate the differences between injection sites in the midthigh and the upper lateral quadrant of the gluteal area regarding the effect, depth of subcutaneous tissue, side effects, and patient preference in patients with cluster headache who self-inject 6 mg (0.5 ml) of sumatriptan. Our open, prospective clinical study was performed at the outpatient department of a Swedish university clinic. There were 19 male and one female subjects, 34 to 68 years old, suffering from cluster headache. We measured the subcutaneous tissue depth by ultrasound. Subjects performed four self-injections of sumatriptan, two in the thigh and two in the gluteal area. We evaluated the subcutaneous tissue depth from the skin surface to the muscle fascia, the effect on headache, side effects, and patient preference regarding the injection site. Subcutaneous tissue depth laterally in the thigh was 2 to 12 mm (median, 4 mm) and in the gluteal area was 34 to 68 mm (median, 45 mm). The needle of the self-injector protrudes 5 to 6 mm. Forty thigh and 39 gluteal injections were recorded. The effect on headache was equal. Following injection in thigh the patients experienced more bleeding (p < 0.001, chi 2); local pain (p < 0.05, chi 2); and a feeling of oppression in the head, neck, and chest area (p < 0.05, chi 2); compared with injections in the gluteal area. Fifteen patients preferred the gluteal area as the injection site after the study, two patients had no preference, and three preferred the thigh. When using the self-injector in the lateral aspect of the thigh, intramuscular injection is liable to occur frequently in male patients. This may explain the differences in local and general side effects observed in this study. The upper lateral quadrant of the gluteal area is a more suitable injection site for male, and some female, patients when using the sumatriptan self-injector.

Pain in the thigh following total hip replacement with a porous-coated anatomic prosthesis for osteoarthrosis. A five-year follow-up study.

We performed a study to determine the prevalence, severity, and natural history of pain in the thigh in patients who had a total hip replacement with a porous-coated anatomic prosthesis and to determine if there was an association between the radiographic findings and the pain in the thigh. We previously reported the results in these patients two years after the operation. The present study included ninety-four patients (101 total hip replacements) who had been followed for a minimum of five years--six of the original group of patients had died from unrelated causes, two had had a revision, and one had been lost to follow-up. The patients were assessed prospectively with use of the Harris hip score and a visual-analog scale for pain in the thigh. Two of us, who were blinded to the clinical result, reviewed the radiographs retrospectively for the morphology of the proximal aspect of the femur; distal fit; metaphyseal fill; alignment of the stem; shedding of beads; distal cortical hypertrophy; pedestal formation; cancellous condensations at the distal end of the porous ingrowth surface; and the presence, extent, and location of radiolucent lines around the femoral component. At five years, pain in the thigh was found in association with twenty-seven hips (27 per cent). The pain was new in fourteen thighs (14 per cent), unchanged (from that at the two-year follow-up examination) in eight (8 per cent), increased in four (4 per cent), and decreased in one (1 per cent). Pain in the thigh was most strongly associated with a poor Harris hip score and the presence of loose beads.
