[Contractures and growth disturbances in the hip and pelvis as the cause of "idiopathic scoliosis". Biomechanical considerations].

Author's own observations on etiology of "idiopathic scoliosis" in children and adolescents are presented. Abduction or flexion-abduction contracture of the hip, mainly right one, is the chief cause of "idiopathic scoliosis". Scoliosis is the final deformity in the chain of malformations commencing in newborns and infants, known as "contracture syndrome". This condition is described by many authors, Mau and Green-Griffin were the first ones. Adduction contracture of the left hip leads to secondary dysplasia of this joint. Coexisting abduction contracture of the right hip is usually neglected. Insufficient adduction in the right hip in extension causes functional elongation of the right extremity and oblique positioning of the pelvis, thus initiating left hand side lumbar, thoraco-lumbar or lumbo-sacral scoliosis. As the next step thoracic scoliosis develops. Early and late clinical and radiographic symptoms are presented, prophylactics and treatment is discussed.

Iliopsoas haemorrhage in patients with haemophilia: results from one centre.

Iliopsoas haematoma is a well-recognized complication of haemophilia, and is considered as potentially life threatening and significantly associated with morbidity. There are only rare reports on the incidence or outcomes of iliopsoas bleeding since the widespread usage of modern therapies for haemophilia. In this study, we present the experience of Ege University Haemophilia Centre with iliopsoas bleeding and its early and late complications. We reviewed 146 haemophiliacs (106 haemophilia A, 40 haemophilia B). Fourteen iliopsoas bleeding episodes were identified in eight haemophiliacs. Three patients (37%) had one episode, four (50%) had two episodes and one (13%) had three episodes. Two patients had a high titre inhibitor against factor VIII and accounted for three bleeding episodes (21%). We did not observe any episodes in six patients receiving prophylaxis. Iliopsoas haematomas were confirmed by ultrasonography in all patients. In physical examination, the most common symptoms were thigh, hip and groin pain, hip flexion contracture, abdominal tenderness and paraesthesia in the distribution of the femoral nerve. The mean duration of therapy with clotting factor concentrate was 7.8 +/- 1.6 days. The mean duration of hospitalization was 4.8 +/- 2.0 days. All patients started to receive a physical therapy program 6.0 +/- 2.4 days after the initiation of haemostatic therapy which lasted 20.0 +/- 6.0 days. Ultrasonographic findings related to iliopsoas haematoma disappeared in all patients within 3 months from the initial episodes. Only in one patient with mild haemophilia A, heterotopic bone formation (myositis ossificans) developed as a long-term complication. In conclusion, pain around the hip joint, femoral neuropathy and hip flexion contracture in a patient with haemophilia should alert the physician to the possibility of an iliopsoas haematoma. Early and effective factor replacement therapy is essential in the prevention of the complications.

[Restorative-reconstructive surgery of the sequelae of osteomyelitis of the lower extremities].

Results of reconstructive-restorative operations on 40 patients with sequellae of acute hematogenic osteomyelitis of lower extremities are described. Most frequent of them are pathologic dislocations, axial extremity, ankylosis and contractures of large vessels in a faulty position. Extrafocal compression-distraction osteosynthesis after Ilizarov was used. Little-traumatic character of the method, stable fixation and early functional loading gave smooth course of the postoperative period and good anatomo-functional results in most of the patients.

Curves of the achondroplastic spine: a new hypothesis.

The profile of the achondroplastic dwarf reflects abnormalities in the shape of the spine, particularly in the lumbosacral area. We hypothesize that these abnormalities and the resultant symptoms are secondary and avoidable rather than heritable and inevitable. Because the heads of achondroplastic children are enlarged (n = 50), loading of the vertical spine is increased. Unusually lax ligaments and misshapen vertebrae predispose the spine to yielding under vertical stress. Children and adults uniformly have hip flexion contractures (n 105); these are hypothesized to be the result of uncorrected lumbosacral lordosis. The volume of the spinal canal, reduced by the spinal stenosis of achondroplasia, is decreased additionally by lordosis; some neurologic deficits of achondroplasia are caused by this abnormal curvature. This hypothesis bears practically on treating this common form of dwarfism.

Camptocormia: a biomechanical analysis. A case report.

Although camptocormia, a conversion disorder associated with the disability of severely forward-bent posture, has been reported in the literature, to date there has been no report of a detailed kinematic or biomechanical analysis of this disability. Presented is a 47-yr-old male engineer with severely forward-bent posture during walking. One year ago, after playing tennis, he developed low back pain followed by a sensation that to walk comfortably he had to assume a forward-bent posture. Two months later, although the low back pain had resolved, he maintained the same unusual walking pattern. Although he could walk a few steps in the upright position, he would spontaneously revert to the forward-bent posture. Physical examination was normal except for bilateral 10 degree hip flexion contractures. Gait laboratory analysis, including kinematics, kinetics, and dynamic electromyography, revealed exaggerated anterior pelvic tilt during terminal stance when he walked in an upright posture. In the forward-bent posture, however, this anterior pelvic tilt was significantly less. It is possible that his unusual forward-bent posture was a compensatory mechanism to reduce excessive pelvic tilt. Although this rare disability has been previously attributed to a conversion disorder, there may be, in some instances, a biomechanical component.

Ambulation in patients with myelomeningocele: a multivariate statistical analysis.

Factors determining ambulation in 163 patients with myelomeningocele were studied by a multivariate statistical method. Neurological dysfunction unrelated to the plaque was analyzed by magnetic resonance imaging. There were no ambulators at the thoracic or L1-L2 level. At the L3 level, 54% ambulated, and at the L4 level, 67% ambulated. Eighty percent were ambulators at L5 and all at the sacral level. Below L1-L2, one-half of the nonambulators had neurological deficiencies caused by syringohydromyelia or Chiari malformations preventing ambulation. Severe scoliosis was closely, age moderately, and hip flexion contracture slightly related to the inability of the other nonambulators to walk, while pelvic obliquity, hip dislocation, or knee flexion contracture was not.

The midlumbar myelomeningocele hip: mechanism of dislocation and treatment.

We define the "bowstring" force of the iliopsoas, the force applied to the femoral head as the tendon angles across the hip joint, which we believe is an important cause of dislocation of the hip in patients with a midlumbar myelomeningocele. An operative procedure consisting of iliopsoas recession and suture of its tendon to the anterolateral hip joint capsule has been developed and used in 10 dislocated and 9 subluxated hips. The procedure was performed on patients with an average age of 6.6 months; the average follow-up was 45 months. Arthrography demonstrated the subluxation pattern of Leveuf in 17 hips. Surgical observations included: (a) flattening of the femoral head beneath the iliopsoas, (b) "bowstringing" of the iliopsoas across the hip joint, (c) posterolateral displacement of the femoral head with hip extension, (d) apparent increase in leg length after release of the iliopsoas, and (e) decrease of hip flexion contracture after iliopsoas release. Following iliopsoas recession alone, 11 hips were stable; 7 had subluxation; 1 was dislocatable. Secondary varus derotation osteotomy for valgus and anteversion was performed on five hips with subluxation; each was stable at review. A combined varus derotation osteotomy and Chiari osteotomy was performed on the one dislocatable hip that remained dislocatable. Therefore, at review 16 of 19 hips were stable, two have subluxation, and one was dislocatable. Early surgical treatment to prevent secondary adaptive changes in the hip is recommended. Additional surgery to correct retained valgus and anteversion is frequently necessary to achieve stability.

Hip dislocation in cerebral palsy: selection for treatment.

Forty-five patients with cerebral palsy hip-dislocation were reviewed and it was found that some did well without treatment. For patients with hip pain, the best results were obtained with extensive resection arthroplasty: soft-tissue surgery alone was unsuccessful. Open reduction with femoral osteotomy achieved concentric reduction in all 15 patients who had this type of surgery: however, most retained their abnormal postural reflex activity to such a degree that subsequent scoliosis, pelvic obliquity, hip extension contractures and knee flexion deformities compromised the success of the hip surgery.

Flexion contractures of the knee following poliomyelitis.

Contractures of the knee after poliomyelitis are common in children in developing countries and treatment, particularly that of severe contractures, presents a surgical challenge. This paper describes a new method for correcting contractures of the knee. Mild contractures need manipulation only and a plaster cast. Moderate contractures are treated by a partial soft-tissue release of the hamstrings and fascia lata followed by gradual stretching of the remaining soft-tissues by manipulation and plaster. Where the contracture is severe, skeletal traction is used through Steinmans pins inserted into the tibia and os calcis. One hundred and thirty-six knees with varying degrees of contracture were treated by these methods. Full correction was achieved and then maintained by plaster immobilisation, physiotherapy and calipers. This prevented recurrence during an average follow-up period of two and a half years. The severity of the contracture of the knee was in direct proportion to the severity of associated flexion-abduction contractures at the hip and equinus deformity at the ankle, the degree of muscle imbalance. All of the contractures of the hip and some of the ankle (46.8%) needed simultaneous operative correction. The basic method is technically simple, requires no special equipment and the results recommend its use particularly in developing countries.
