Tilted lateral radiographs in the evaluation of intra-articular distal radius fractures.

The anatomy of the distal radius confounds the assessment of fracture displacement of the lunate facet. Since reduction of the articular surface is paramount to obtaining good clinical results, this study was designed to evaluate whether a radiograph taken 22 degrees from true lateral (forearm held at a 22 degrees angle from the horizontal film cassette) would enhance the accuracy of measuring displacement. Fifteen lunate facet fractures of varying depression were produced in 7 fresh cadaveric wrists. Posteroanterior (PA), standard lateral, and 22 degrees tilted lateral radiographs were obtained of each fracture pattern. Four observers reviewed the films and measured the depression of the fragments from their anatomic position. Measurement error from actual depression averaged 1.1 mm when the evaluators evaluated the 22 degrees lateral and PA films, 1.5 mm for the standard lateral and PA views, and 0.8 mm for the standard lateral, 22 degrees lateral, and PA radiographs (combined group). The decrease in measurement error obtained from all 3 groups was statistically significant. The results of this study suggest that the 22 degrees tilted lateral, either in combination with the standard lateral radiograph or just with the PA view, may help the hand surgeon better understand the intra-articular depression of lunate facet fractures of the distal radius.

Volar fixed-angle fixation of distal radius fractures: the DVR plate.

Volar fixed-angle fixation of distal radius fractures is a new method of treatment that provides the benefits of stable internal fixation without incurring the disadvantages of the dorsal approach. The DVR plate is a new fixation implant that was introduced specifically for the purpose of managing both dorsal and volar displaced fractures from the volar aspect. Experience gained applying volar fixed-angle fixation to clinically complex cases led to the description of a new surgical approach and to refinement in design of the implant. The need to reduce fractures with significant articular displacement and the need to debride dorsal organized hematoma or callus in old fractures led to the development of an extended form of the flexor carpi radialis approach that provides improved dorsal exposure by mobilizing the proximal radius out of the way and allows the use of the fracture plane for intrafocal exposure. The use of this implant in severely osteoporotic bone and in those fractures presenting severe articular fragmentation or displacement led to the improvement of its design. The plate's ability to stabilize the distal radius was optimized by taking full advantage of the principles of subchondral support and buttress fixation.

[Osteosynthesis of distal radius fractures with biodegradable fracture rods. Results of two years follow-up].

Forty distal fractures of the radius were stabilized with biodegradable polyglycolic acid rods (Biofix). A forearm plaster cast was fit for 4 weeks. Nine patients developed late (4 to 16 weeks) aseptic inflammatory reactions at the pin site, which were treated by débridement. The histological specimens showed giant-cell phagocytosing fragmented polyermic debris. In two cases a bacterial wound infection occurred secondary to débridement. All local reactions healed within 4 weeks. A classification system and treatment regimen for these inflammatory reactions are proposed. Thirty-four patients (including those with local foreign body reaction) were available for the 2-year follow-up. The anatomical results of fracture reduction on the postoperative and follow-up radiograms were the same, confirming good mechanical fracture stabilization. According to the Sarmiento score, the overall results were excellent and good in 31 cases. In one of the three fair cases, the result was clearly due to the initial local foreign-body reaction. Because of the high incidence of local inflammatory reaction, for now clinical application of biodegradable implants seems problematic despite the good overall 2-year results. This should only be advocated for well-controlled prospective studies using implants with improved biocompatibility.

[Complex distal radius fracture: value of spongiosa-plasty in combination with external fixator treatment].

22 Patients with complex fracture of the distal radius (Fernandez III/Frykman VII-VIII/AO 23.C) underwent treatment with external fixation and auxiliary autologous bone grafting in purpose to reconstruct and stabilize the radiocarpal articular surface, reset the radius length, obtain a quicker bone healing and avoid secondary radius shortening after removing of the external fixation. In spite of reassessment of radius length in 80% and reconstruction of the radiocarpal articular surface in 75%, late control showed the development of radiological signs of radiocarpal arthritis. 50% of the patients have a moderate loss of strength and motility in the wrist; this seems to be a good result for a very negative selection of complex fractures of distal radius. We recommend autologous bone grafting in treatment of complex fractures of the distal radius with external fixation.

Use of bone graft substitutes and bioactive materials in treatment of distal radius fractures.

Although autogenous bone graft has been shown to be useful in the treatment of distal radius fractures, the role of bone graft substitutes and the optimal replacement material remains unclear. Several products are commercially available, each with differing osteoconductive, osteoinductive, and structural properties. Indications and choice of graft substitute should be based on the needs of the individual case with regard to need for structural support, gap filling, or bone healing stimulation. Further comparative research will help clarify the indications and most appropriate material for a given fracture and clinical situation.

[Conservative treatment of classical radius fractures].

In Colles' fractures of the radius the distal fragment is slanted dorsally and radially, dislocated dorsally and radially and supinated. The radius is shortened. Furthermore a comminution-zone of the dorsal cortex is found. In closed reduction the fracture is unwedged and reduced by recreating the mechanism of trauma in neutral position, rather a light dorsiflection is maintained to check secondary dislocation of the distal fragment and shortening of the radius. The cast should push the carpus slightly palmwards and hold the hand in light ulnar-duction. Immobilization is retained for four to six weeks. Radiologic review is performed 4, 8, 12 and 16 days post reduction so that timely change to a different form of fixation is possible in case of secondary dislocation.

Initial experience with the Forte plate for dorsally displaced distal radius fractures.

Open reduction and plate osteosynthesis is occasionally indicated for dorsally displaced distal radius fractures. We reviewed our medium term results with the Forte plate, one of the recently introduced purpose-made implants.Twenty-five patients operated on during the first year were reviewed 19 (12-24) months after surgery. Median age at operation was 53 (28-80) years. There were seven high energy and eighteen low energy injuries. Fourteen fractures extended into the radiocarpal joint.Three patients had a poor clinical result and were re-operated on before review with an arthrodesis, ulnar shortening, or Sauve-Kapandji operation. The remainder had six excellent, twelve good, and four fair results. Irritation of the extensor tendons was a minor problem. Initial radiological correction of deformity was satisfactory, but increased volar angulation of the distal radius was seen at follow up in twenty patients - by more than 10 degrees in nine. Seven patients had 20-30 degrees volar tilt at final review and tended to have a poorer clinical result than other patients. In our patients use of the Forte plate seems to have given satisfactory clinical results, but the increase in volar tilt after surgery is a cause for concern.

[Distal radius fractures: consistency of the classifications].

OBJECTIVE: The purpose of this study was to determine the intra-observer and interobserver reproducibility of Frykman, AO and Universal classifications for the fractures of the distal radius. METHODS: In this study, 40 radiographs of fractures of the distal radius were selected and classifed by orthopedists of different centers and levels of experience, determining the intra-observer and interobserver reproducibility of the classifications using Kappa statistic method. RESULTS: The medium intra-observer concordance observed was moderate to Frykman and Universal classifications and light to the AO system. The medium interobserver reproducibility was light in the two readings to Frykman and Universal classifications and despicable in the second reading of the AO classification. CONCLUSION: All the classifications used presented questionable interobserver reproducibility compromising the use of the three evaluated systems.

[A new classification of distal radius fractures and corresponding treatment methods].

Based on previously published reports on fractures of the distal radius and on the analysis of 400 fresh fractures treated in two accident hospitals affiliated with our university hospital, we propose a new classification as shown in Table 2. This new classification includes a type of combined Chauffeur-Barton fracture which has never been described before. Each type of fracture of the distal radius requires a specific treatment as shown in Fig. 1.

[The importance of the distal radioulnar joint for reconstructive procedures in malunited distal radius fracture].

Clinically most patients complain about ulnar sided wrist pain and limited forearm rotation following malunited distal radius fractures. Possible bony reasons consist of intraarticular incongruency, malalignment of the sigmoid notch of the distal radius or the ulna-plus-situation at the wrist level. A persisting luxation of the distal radioulnar joint (DRUJ) will present itself with complete loss of forearm rotation. The ligamentous or bony detachment of the triangular fibrocartilage complex (TFCC) will lead to instability of the DRUJ. Uncorrected, each of these components will lead to arthrosis of the DRUJ. The presence of arthrosis only allows salvage procedures for the DRUJ and will lead to functional loss. Reconstructive options consist of radius correction osteotomy, ulnar shortening osteotomy, reposition of a luxation and refixation of the TFCC. To chose the necessary reconstructive procedure, the individual pathological situation has to be analysed.

Treatment of unstable extra-articular distal radius fractures by modified intrafocal Kapandji method.

The authors prospectively assess the results of surgically treated, unstable extra-articular distal radius fractures from 29 patients with good bone quality. Mean age was 49 years, ranging from 22 to 69 years; the female gender was the most frequently affected (58.6% of the cases). Surgical fixation was indicated for fractures presenting an angulation above 20 degrees , marked dorsal comminution, and radius shortening in excess of 10 mm on initial x-rays (anteroposterior and lateral views). The Kapandji technique, with intrafocal, nonthreaded Kirschner wires, was employed. Clinical data assessed anatomic aspects according to Scheck, functional aspect after Gartland and Werley, strength by Scheck's methods, and esthetic by Frykman's criteria. Functional assessment, according to Gartland and Werley, revealed 72.1% of excellent and good results at 3 months; 89.7% at 6 months; and 96.6% at 12 months. Immediate postoperative reduction was not maintained at the final follow-up at 12 months; however, that loss was not severe, and the anatomic outcome was good and excellent in 96.6% of the cases. Six patients presented complications. Four patients presented reflex sympathetic dystrophy; 1 patient had a superficial Kirschner wire infection, and another patient had radial nerve superficial branch paresthesia. The employed technique showed to be effective in the treatment of unstable, extra-articular fractures of the distal radius. It is easy to learn and to perform. The device employed has a low cost and is widely available in operation rooms.

Clinical application of double dorsal plates for the distal radius fractures.

The purpose of this study was to develop plates that fit the contour of the distal radius of the Japanese and can be inserted less invasively. Three-dimensional models of 36 radii of 18 volunteers were prepared. Using these models, the shape of the cortical bone on the radial margin of the distal radius and just below the dorsal fourth compartment of the wrist, to which the plates were expected to be applied, was measured, and the curves of the plates were determined. The functions of approximated curves of the plates were: [y = -2 x 10(-8) x5 - 2 x 10(-6) x(4) + 0.0006 x3 - 0.0312 x2 + 0.3274 x + 15.224 on the radial margin of the distal radius and [y = 7 x 10(-7) x5 - 0.0001 x4 + 0.0078 x3 - 0.2355 x2 + 3.1815 x - 5.6383 just below the fourth compartment. The clinical results of the application of double dorsal plates were satisfactory in clinical cases for the distal radius fractures.

[Bore wire osteosynthesis in distal radius fractures].

In the presence of an area of extensive dorsal comminution percutaneous pinning is indicated in a typical distal radius fracture (Colles). It enlarges the stability and thus helps avoiding a secondary dislocation of the fracture. Indication and technique of this procedure are discussed following a series of 66 patients. Typical mistakes are as follows: insufficient reduction, poor diverging of the K-wires and improper anchoring in the opposite cortex. Avoiding of these possible faults leads to good final results. Flexion fractures and extensive shattering of the bone are contraindications for percutaneous pinning of these fractures.

Operative treatment of intra-articular distal radius fractures using the small AO external fixation device.

BACKGROUND: A retrospective group study was done to evaluate the effect of the small AO external fixator in the management of acute intra-articular fractures of the distal radius. METHODS: Between January 1995 and December 1996, 70 consecutive patients with articular fractures of the distal radius were treated by closed reduction and external fixation with small AO external fixators. The mean age at the time of surgery was 58.9 years (range, 14-87 years). There were 58 Colles' Barton's fractures and 12 Smith's Barton's fractures. The follow-up period was 104 months (range, 92-118 months). RESULTS: All fractures united in a mean of 5.8 weeks (range, 4-10 weeks). At the final follow-up, the average range of motion was 56.3 +/- 11.6 degrees in flexion, 58.6 +/- 10.7 degrees in extension, 21.5 +/- 4.2 degrees in ulnar deviation, 9.1 +/- 2.9 degrees in radial deviation, 71.5 +/- 8.5 degrees in pronation, and 67.3 +/- 9.2 degrees in supination. Compared with the normal side, the average grip force was 87 +/- 6%. The overall clinical and functional outcomes, according to the scoring system of Gartland and Werley, showed that 22 patients (31.4%) had excellent results, 36 (51.4%) had good results, 9 (12.9%) had fair results, and 3 (4.3%) had poor results. CONCLUSION: Closed reduction and external fixation with the small AO external fixator is useful and effective in the management of displaced comminuted articular fractures of the distal radius.

[Distal radius fracture. Surgery or plaster cast?]].

Fractures of the distal radius are most commonly seen in women in the sixth and seventh decade of life. These fractures range in severity from simple, stable non-dislocated metaphyseal transverse fractures of the distal radius to complex, intra-articular fractures of the wrist with involvement of the carpus. This means that individual consideration of the appropriate therapeutic approach that needs to be adopted is required. A decisive role for surgical treatment is played by the anatomical angles at the radiocarpal articular surface, and the congruence of the distal radio-ulnar joint. If care is not taken to establish proper anatomical relationships, persistent problems must be expected.

Assessment of complications of distal radius fractures and development of a complication checklist.

The purposes of this study were to determine the overall incidence of distal radius fracture (DRF) complications, determine the incidence and types of DRF complications in a consecutive cohort of 250 patients with DRFs, describe DRF complications reported by patients compared with those reported by physicians, and formulate a DRF complication checklist to improve recording of DRF complications. We found that the overall complication rates vary widely (6% to 80%). Physician-reported complication data were collected for 236 patients, and a physician-reported complication rate of 27% was determined. A patient-reported complication rate of 21% was found for 207 patients whose patient-reported data were collected. We also noted that patients and physicians assess DRF complications differently: patients are more focused on symptoms than diagnoses. A DRF complication checklist was developed to improve prospective data collection. The checklist includes a classification for all DRF complications and allows for assessment of severity of each complication.

[Screening for postmenopausal osteoporosis. Women with distal radius fractures should be evaluated for bone density].

In a case-control study at two country hospitals in Sweden, 110 consecutive postmenopausal women (age 50-75) with distal radius fracture were examined with the DXA-technique, on the injured radius, lumbar spine, and the right hip within three weeks after the fracture occurrence. Data was compared with 55 age-matched controls from The Swedish Population Register. The incidence of osteoporosis according to WHO's definition (T-score < -2.5) at any measurement site was higher in the fracture group, 44 per cent compared with 27 per cent in the control group. The fracture group had 12 per cent lower bone mineral density in the distal radius compared with the control group. A higher rate of previous fractures was noted in the fracture group compared with the control group. The study reflects the situation in general health care, where osteoporosis is common in postmenopausal women with distal radius fracture. This patient group can easily be identified and is suitable to be diagnosed for osteoporosis using bone density measurement prior to a decision being reached with regard to any treatment. According to the guideline for medical treatment (T-score < -2.0 and fragile-fracture) as outlined by the Swedish Osteoporosis Society, 75 per cent of postmenopausal patients with forearm fracture should be considered for such treatment.
