Paralytic dislocation of the hip in myelodysplasia. The role of the adductor transfer.

In thirty-nine patients with myelodysplasia at the third, fourth, or fifth lumbar level and subluxation or dislocation of the hip (fifty-nine hips involved), the following surgical approaches were utilized to balance the muscles about the hip: In one group (twenty hips in eleven patients) the origins of the adductors longus, brevis, and gracilis were transferred to the ischial tuberosity, and in fifteen hips in that group the iliopsoas also was transferred to the greater trochanter when the abductors were severely weakened. In the second group (thirty-nine hips in twenty-eight patients), only the iliopsoas transfer was done. Group I patients demonstrated improved muscle balance with less severe flexion-adduction contractures; increased power in abduction and extension; and a higher incidence of stable hips at follow-up.

[Orthopaedic problems in adults with cerebral palsy].

BACKGROUND: There is little information about the need for orthopaedic surgery in adults with cerebral palsy; we wanted to assess this problem. MATERIAL AND METHODS: The material included 37 adults with cerebral palsy (19 women and 18 men), mean age 39. The degree of physical disability was mild in 19 cases, moderate or severe in 18. The patients were assessed by clinical examination and radiographs of hips and spine. RESULTS: 15 patients had pain located to the spine or lower extremities but no-one had severe or invalidating pain. Subjects with moderate or severe disability had a markedly reduced range of motion in the hip and knee joints. Subluxation or dislocation of the hip joints was found in six patients but only one of them had hip pain. Orthopaedic surgery had been performed in 23 patients. In 8 patients we found indications for additional orthopaedic surgery aimed at relieving pain, reducing contractures or improving function. The most frequent procedures would be tenotomies in the hip and knee regions, heel cord lengthening, and triple arthrodesis of the foot. INTERPRETATION: Regular follow-up of adults with cerebral palsy is recommended in order to reveal musculoskeletal problems that can be improved by orthopaedic surgery.

Progressive bone and joint abnormalities of the spine and lower extremities in cerebral palsy.

Bone and joint changes in cerebral palsy result from muscle spasticity and contracture. The spine and the joints of the lower extremity are most commonly affected. Scoliosis may progress rapidly and may continue after skeletal maturity. Increased thoracic kyphosis and lumbar lordosis, spondylolisthesis, spondylolysis, and pelvic obliquity may accompany the scoliosis. Progressive hip flexion and adduction lead to windswept deformity, increased femoral anteversion, apparent coxa valga, subluxation, deformity of the femoral head, hip dislocation, and formation of a pseudoacetabulum. In the knee, flexion contracture, patella alta, and patellar fragmentation are the most commonly seen abnormalities. Recurvatum deformity can also develop in the knee secondary to contracture of the rectus femoris muscle. Progressive equinovalgus and equinovarus of the foot and ankle are associated with rocker-bottom deformity and subluxation of the talonavicular joint. Early recognition of progressive deformity in patients with cerebral palsy allows timely treatment and prevention of irreversible change.

Soft-tissue release of the hips in children with juvenile chronic arthritis.

In juvenile chronic arthritis the hips are commonly affected and this becomes the most important reason for losing independence and mobility: the joint develops a painful flexion contracture with marked loss of movement. Soft-tissue release operations consisting of psoas and adductor tenotomies have proved a safe and effective method of relieving pain and improving function. We report 89 such operations in 52 patients. More extensive soft-tissue release operations or synovectomy of the hips offer no advantage and recovery is often more painful and prolonged.

Intracapsular pressure and pain in coxarthrosis.

Intracapsular hip pressure was measured before surgery in 17 patients (18 hips) with coxarthrosis. The results were correlated to pain as registered on a visual analog scale. With the hip in extension, the pressure was 49.5 mmHg (SD, 40.2); in 45 degrees of flexion, it was 21.3 mmHg (SD, 14.6); in extension and inward rotation, it was 105.7 mmHg (SD, 76.0); and in extension and outward rotation, it was 40.8 mmHg (SD, 32.0). A small amount, 0.7 mL (SD, 1.14), of joint fluid was aspirated following pressure registration. Pressure correlated significantly to pain at night, when starting to walk, and on walking. It is suggested that the increase in intracapsular hip pressure is a cause of pain in coxarthrosis, with subsequent limitation of movement and joint contracture.

Posterior transfer of the adductors in children who have cerebral palsy. A long-term study.

Seventy-eight posterior transfers of the adductors of the hip in forty-two children who has spastic cerebral palsy were reviewed an average of 5.7 years after the operation (range, two to 14.6 years). The results were assessed on the basis of the patient's ability to walk, the range of motion of the affected hip or hips, and the radiographic measurements. In 88 per cent of the patients, the transfer was successful in improving or maintaining abduction, extension, functional walking, and stability of the hip. The failures were all in patients who were unable to walk and who had spastic quadriplegia. Tenotomy of the iliopsoas tendon at the time of the transfer procedure resulted in an improved range of motion of the hip.

[Joint preserving operations and endoprosthetic joint substitutions in hemophiliacs. Indications and long term results].

Hemophilic arthropathy is the result of recurrent joint bleedings in patients with severe haemophilia A or B and von Willebrand Syndrome. Conservative orthopaedic treatment is preferred in every stage of the arthropathy. Synovectomy is indicated only after failure of the conservative regimen after 3 to 6 months in order to control synovitis and recurrent bleeding. This paper presents the indications, methods, and results of different joint preserving operations. Especially synovectomy of the elbow joint with or without radial head resection shows very good long term results. Radiosynoviorthesis is an alternative in certain cases. The end stages of hemophilic arthropathy are characterised by pronounced joint contractures. We achieved very good long term results by implanting total hip joints (n = 13) and total knee joints (n = 20) with a median follow up of 102 respectively 53 months. No perioperative complications like bleeding or infection were registrated. Only one aseptic loosening of a cemented cup occurred 14 years postoperatively as well as one septic loosening 14 months postoperatively in an HIV positive haemophilic. Another HIV positive patient developed a hematogenic abscess on both operated on hips without loosening of the endoprosthesis. Bicondylar prosthesis (n = 14) showed 6 very good, 6 good and 2 fair results in the HSS-score. Only one subsidence of an uncemented tibia plateau without definitive loosening occurred 55 months later. The functional results of constrained knee endoprostheses (n = 6) were not as good (2 good, 2 fair, 2 poor). However, these patients suffered preoperatively from severe contractures and malalignments. Aseptic loosening or late infections did not occur even in case of HIV infections.

Treatment of acquired hip subluxation in cerebral palsy.

Fifty-seven children with cerebral palsy and subluxated hips underwent soft tissue releases to obtain hip reductions. Eight patients in Group I (preoperatively mildly subluxated hips) had postoperative bracing, all with good results. Twenty-two unbraced patients in Group I had 14 good, 5 fair, and 3 poor results. Thirteen patients in Group II (preoperatively severely subluxated hips) received postoperative splinting with nine good, one fair, and three poor results. The 14 unbraced patients in Group II had one fair and 13 poor results. This study indicates that even severely subluxated hips in spastic children less than 6 years of age can eventually achieve stable reductions provided long-term abduction bracing is used following adequate soft tissue releases.

Effects of paralysis with pancuronium bromide on joint mobility in premature infants.

To study the effects of muscle paralysis on joint mobility, we compared eight premature infants treated with pancuronium bromide with a control group. A significant reduction was observed in hip and knee flexion, and in ankle dorsal extension, which tended to resolve in time. We conclude that muscle paralysis reduces the mobility of selected joints; spontaneous activity appears to prevent long-term contractures.

Biomechanical characterization and clinical implications of artificially induced toe-walking: differences between pure soleus, pure gastrocnemius and combination of soleus and gastrocnemius contractures.

The purpose of this study was to characterize biomechanically three different toe-walking gait patterns, artificially induced in six neurologically intact subjects and to compare them to selected cases of pathological toe-walking. The subjects, equipped with lightweight mechanical exoskeleton with elastic ropes attached to the left leg's heel on one end and on shank and thigh on the other end in a similar anatomical locations where soleus and gastrocnemius muscles attach to skeleton, walked at speed of approximately 1m/s along the walkway under four experimental conditions: normal walking (NW), soleus contracture emulation (SOL), gastrocnemius contracture emulation (GAS) and emulation of both soleus and gastrocnemius contractures (SOLGAS). Reflective markers and force platform data were collected and ankle, knee and hip joint angles, moments and powers were calculated using inverse dynamic model for both legs. Characteristic peaks of averaged kinematic and kinetic patterns were compared among all four experimental conditions in one-way ANOVA. In the left leg SOL contracture mainly influenced the ankle angle trajectory, while GAS and SOLGAS contractures influenced the ankle and knee angle trajectories. GAS and SOLGAS contractures significantly increased ankle moment during midstance as compared to SOL contracture and NW. All three toe-walking experimental conditions exhibited significant power absorption in the ankle during loading response, which was absent in the NW condition, while during preswing significant decrease in power absorption as compared to NW was seen. In the knee joint SOL contracture diminished, GAS contracture increased while SOLGAS contracture approximately halved knee extensor moment during midstance as compared to NW. All three toe-walking experimental conditions decreased hip range of motion, hip flexor moment and power requirements during stance phase. Main difference in the right leg kinematic and kinetic patterns was seen in the knee moment trajectory, where significant increase in the knee extensor moment took place in terminal stance for GAS and SOLGAS experimental conditions as compared to SOL and NW. The kinetic trajectories under SOL and GAS experimental conditions were qualitatively compared to two selected clinical cases showing considerable similarity. This implies that distinct differences in kinetics between SOL, GAS and SOLGAS experimental conditions, as described in this paper, may be clinically relevant in determining the relative contribution of soleus and gastrocnemius muscles contractures to toe-walking in particular pathological gait.

The phenotype of calpainopathy: diagnosis based on a multidisciplinary approach.

Calpainopathy (LGMD2A) is the most common type of autosomal recessive limb-girdle muscular dystrophy. We performed a systematic clinical evaluation in 13 calpainopathy patients from 11 families, with particular attention to the pattern of muscle involvement. Eleven patients had a muscle biopsy with deficiency of calpain 3 on western blotting. The other two patients were not biopsied as they were siblings from the same families. Confirmatory CAPN3 mutations were detected in seven patients. The age at presentation was 2-45 years, wider than previously reported. We confirm the highly characteristic and recognisable phenotype of predominant muscular atrophy with early pelvic girdle involvement, relative sparing of the hip abductors, scapular winging and abdominal laxity. Early primary contractures were also a prominent feature in this group, expanding the breadth of the phenotype. Recognition of the clinical pattern of calpainopathy is of diagnostic significance. It is important, especially in sporadic cases, in targeting and interpreting laboratory investigations in order to provide accurate diagnostic and prognostic information.

Reciprocating orthoses for children with myelomeningocele. A comparison of two types.

Since 1987, 22 children with myelomeningocele have been fitted with reciprocating orthoses. The level of the spinal lesions ranged from T10 to L4 and 13 had associated spinal deformities. Twelve of the patients currently use a Reciprocating Gait Orthosis, seven use a Hip Guidance Orthosis or Parawalker, one has progressed to a Knee Ankle Foot Orthosis, one has died and one has been lost to follow-up. The reciprocating orthoses are worn for a mean of 3.5 hours per day (1 to 6.5); daily usage by girls is almost twice that by boys. The mean daily usage by community walkers is 4.2 hours (13 children) as against 2.8 hours by household ambulators (8 children). Active hip flexion is not essential and fixed-flexion contractures up to 35 degrees can be accommodated. The average breakdown rate is 0.45 per year with an average of 1.5 adjustments each year. The average annual cost of a reciprocating orthosis is Aus$750 (375 pounds, US$570); this includes fabrication, adjustments and repairs.

[Results of surgical correction of flexion contractures of the knee joint in CP children (author's transl)].

Follow-up of 78 CP children with elongation of the tendons of knee flexors. In addition further operations were done in a large number of cases, frequently shortening of the patellar ligament, lengthening of hip flexors and correction of pes equinus. The further motor development shows worsening in 8, no improvement in 28 and improvement in 42 children. Analysis according to age showed better results in children under 9 years: Of the 48 younger children 33 showed progress, 13 free walking. Of the 30 older children only 9 showed progress and only 2 learned to walk freely. This difference was significant. Investigation of the causes for not walking showed the importance of motor preconditioning. Only children who had knee-standing before operation learned free walking. Major lack of motor development was most frequently preventing walking. Further causes were mental retardation, athetosis, pes calcaneus and general flexion patterns. While results in gaining extension at the knee were quite good, outward rotation at the hip averaged an improvement of 9.7 degrees. A favorable influence of combined elongation of knee flexors and adductor tenotomy at the hip in the CE angle was also clear. It diminished on average by 6.9 degrees. Special pre-operative conditions and the technique of examination are discussed in detail.

Hip and shoulder internal rotation range of motion deficits in professional tennis players.

One hundred tennis players were recruited from the professional men's tennis tour to investigate the correlation between hip internal rotation deficits and low back pain (LBP), as well as shoulder internal rotation deficits and shoulder pain. A statistically significant correlation was observed between dominant shoulder internal rotation deficits and shoulder pain. Also observed was a statistically significant correlation between lead hip internal rotation deficits and lumbar extension deficits with LBP. We conclude that due to repetitive demands on the dominant shoulder and repetitive pivoting at the lead hip, the cycle of microtrauma and scar formation leads to capsular contracture and subsequent reduction in internal range of motion. It is likely that the limitation in lumbar extension in the symptomatic group is not only due to decreased flexibility from an increased load on the spine, but also due to a protective mechanism to prevent further exacerbation of the LBP. Physical conditioning that includes shoulder as well as hip internal rotation stretching programs should therefore be essential aspects in the treatment of tennis players with shoulder pain and LBP respectively.

[Surgical treatment of orthopedic deformities due to spasticity in the lower limb].

Orthopedic deformities in the lower limb concern all joints (hip, knee, ankle, foot) with a wide range of clinical forms. Spasticity, contracture, stiffness, laxity, neurological deficit are assessed to establish the surgical procedure. Surgical techniques are adapted to the goals that are detailed with the patient and his family: standing, transferring, walking, hygiene, devices (shoes, orthosis, canes, wheelchair). Surgical procedures can associate: lengthening of contractured muscles (tenotomy with or without sutures, fractional lengthening at the musculo-tendinous junction or desinsertion), strengthening of antagonists (passive or active tendon transfer) and correction of joint deformity (arthrolysis, arthrodesis, arthroplasty). In adults, the most common deformities are the equinus or equinovarus foot, toe curling, hip adductum, knee flessum. Talus or knee recurvatum are less frequently observed. The association of various deformities raises questions concerning the hierarchy of surgical procedure, from an anatomical point of view (do we start with proximal or distal joint first?) as from chronological concerns (shall we do one or more procedures?). Pluridisciplinary assessment using neurological anesthetic blocs and dynamic EMG or gait analysis is necessary to detail the aims of surgery and choose the surgical procedures.

Orthopedic procedures after rhizotomy.

The goal of selective dorsal rhizotomy (SDR) is to reduce surgically abnormal excitatory impulses to the lower extremities and thus to decrease spasticity in patients with cerebral palsy. One hundred thirty-one patients underwent SDR from 1986 to 1994 and were retrospectively reviewed for changes in tone, requirements for orthopedic intervention, and changes in ambulatory status. One hundred twelve patients had adequate follow-up. Postrhizotomy tone was decreased in all of the 112 patients, as measured by the Ashworth scale. No statistically significant change in ambulatory status was found. A total of 71 (65%) of 112 patients required orthopedic intervention for continued contractures and deformity. Of those judged "hypotonic" by the physiatrist postoperatively, 37% required subtalar stabilization for severe planovalgus. Hip subluxation was noted and treated (by femoral or pelvic osteotomy or both) in 27 (25%) of 112. Despite appropriately completed SDR, parents must understand the importance of periodic long-term follow-up and the possible, if not likely, need for additional surgery to alleviate contractures and stabilize subluxation of joints.
