The incidence of scoliosis in cerebral palsy is related to the severity of the neurological involvement, being most prevalent in patients with spastic quadriplegia. Neuromuscular spinal deformity, when present, may progress after cessation of skeletal growth, and the success of orthotic treatment for scoliosis is unpredictable. Hip pathology is directly related to pelvic obliquity but has no causal relationship to the development of scoliosis. Adequate preoperative nutritional assessment is vital to reduce perioperative complications, and segmental spinal fixation is the instrumentation of choice. Anterior arthrodesis is indicated for rigid deformities and for those thoracolumbar and lumbar curves extending into the pelvis with pelvic obliquity and spinal decompensation.

Classification of cerebral palsy according to the topographical distribution of clinical phenomena permits determination of a prognosis of the natural history of CP and the probability of hip problems to some extent. In 55 patients with CP, 101 muscle release operations were performed between 1971 and 1988. Preoperatively, the diagnosis was established by the neuropediatrician, function was evaluated according to the Rancho-los-amigos system, and the X-rays of the hip were assessed according to Reimers. For the postoperative evaluation patients were grouped according to neurologic diagnosis: hemiplegia (4), diplegia (19), total body involvement (31). Patients with hemiplegia had no functional or radiological changes as a result of the operation. In diplegia functional deterioration was seen in 4 cases (21%); in 3 cases (16%) this meant loss of the ability to walk. The migration percentage was improved from 48% to 39% on average. In 19 cerebral palsy patients with total body involvement surgery was considered to be indicated on the basis of a suspected dislocation of the hip. No functional changes occurred as a result of surgery. Hip dislocation was successfully prevented in 90% of the cases. The migration percentage was improved from 73% to 33%. In another 12 patients with total body involvement, adductor and iliopsoas release was performed to allow better hygiene and care and for pain relief. These goals were achieved; neither the Rancho-Los-Amigos function classification system nor X-rays were used to evaluate the results.

Hip flexion contracture was examined in 51 spastic cerebral palsy patients by three clinical methods and two radiologic methods. An extremely low association was found between the clinical and radiologic methods with no particular method, clinical or radiologic, showing a higher association. The method of clinical examination should be chosen by convenience. Radiologic measurements by the methods used did not add useful information.

Seating arrangements for cerebral palsy children with total body involvement are often unsatisfactory and can pose considerable problems for the multi-disciplinary team. Hip joints at risk of dislocation must be kept in an abducted position in order to minimize pain. A new wheelchair with a barrel-shaped cylindrical seat has been developed which improves the femoral head location and alleviates pain.

Hip dislocation in children with cerebral palsy is caused by a combination of factors, including spastic muscle imbalance, persistent fetal femoral geometry, acetabular dysplasia, and flexion-adduction contracture. The incidence of dislocation correlates with the severity of the spasticity, and the prevalence is close to 50% in neurologically immature, spastic quadriplegic children. Successful hip reductions improve muscular balance, provide satisfactory reduction of the femoral head, and establish good pelvic coverage. In 31 occurrences of established hip dislocation in 24 patients, the most successful operations used a combined procedure consisting of soft-tissue release, open reduction, femoral varus derotation and shortening osteotomy, and pelvic osteotomy.

The evolution of tone and reflexes from 25 weeks postmenstrual age (gestational age plus chronologic age) to term in a population of 42 surviving infants is described. The infants were born in 1983 at the Johns Hopkins Hospital, had birth weights less than 1300 g, were examined weekly until neonatal intensive care unit discharge, and did not develop cerebral palsy. Lower-extremity flexor tone was first detectable at 29 weeks post-menstrual age by the popliteal angle and heel to ear maneuvers. Flexor tone, recoil, and hyperreflexia were all noted 2 to 3 weeks earlier in the lower extremities (33 to 35 weeks) than in the upper extremities (35 to 37 weeks). Hip tone (35 to 37 weeks) followed knee flexor tone, but preceded shoulder tone (37 to 38 weeks). Trunk tone on ventral suspension emerged closer to term (36 to 40 weeks), and more than half of infants evaluated at term continued to demonstrate head lag when pulled to sitting position. The emergence of the primitive and pathologic reflexes reflects (both in timing and pattern) the evolution of tone: development of the reflexes in the lower extremities precedes that of those in the upper extremities, and development of the distal reflexes precedes that of the proximal. Maturation of tone, deep tendon reflexes, pathologic reflexes, and primitive reflexes occurs in an orderly, sequential manner, with a well-defined pattern: caudocephalad (lower extremities to upper extremities) and centripetal (distal to proximal).

Two groups of patients with cerebral palsy (CP) were studied pre- and postoperatively by gait analysis after proximal release or distal transfer of the rectus femoris for treatment of knee stiffness in swing phase. In the first group studied, 12 patients underwent proximal rectus femoris muscle release. In the second group, 10 patients underwent distal rectus femoris transfer. After surgery, peak knee flexion was increased 9.1 degrees in swing phase by proximal rectus release and 16.2 degrees by distal rectus transfer. Hip motion throughout the gait cycle was not significantly affected by either operation, and no tendency for a crouch gait was observed after either procedure.

The incidence of significant head injury has been estimated at 220/100,000 children. Over 90% of these will recover with little residual disability. The purpose of this study is to re-examine the small but significant percentage of head injured children with permanent total body involvement to identify patterns of deformity and temporal sequences and to develop preventive treatment regimens. Sixteen head injured children with residual spastic quadriplegia were examined. All exhibited musculoskeletal abnormalities. Hip adduction contractures were most common leading to hip subluxation in eight children, followed by pes equinus, scoliosis, pelvic obliquity, and knee flexion contracture. The average time to onset of permanent foot deformity was 11 months after head injury, for scoliosis an average of 22 months postinjury, and for hip subluxation an average of 31 months postinjury. Hamstring contractures occurred later, at an average of 37 months, but caused the most interference with good seating. The physical problems of the head injured child have some similarities to those of the child with cerebral palsy, but with distinct differences. An aggressive surgical approach to prevention and treatment of fixed deformity in these children is recommended at an early stage with postoperative orthotic management and stable seating in abduction.

Twenty cerebral palsy patients who had undergone soft-tissue surgery at the hip (adductor tenotomy, medial lengthening of the hamstrings) were compared with a matched group of another 20 patients with a similar age range and findings and with additionally performed iliopsoas release, 2 or more years after surgery. Extension deficits of the hip did not improve with the addition of iliopsoas release. Internal rotation deformities showed equal improvement in both groups; the influence of the iliopsoas procedure was not significant. Adduction deformities, as documented on roentgenograms of the hip, showed significant improvement, however. Postural anomalies were not essentially influenced by iliopsoas release. Hip dislocations and subluxations, as assessed by the CE angles, were positively influenced by additional iliopsoas release; however, more effective improvement was obtained with ischiocrural elongation.

A total of 484 premature children and a control group of 114 healthy term children underwent orthopaedic follow-up from birth to 5 years of age. At birth, metatarsus adductus was found to be more frequent in twins than in single infants (41% vs 16%; P less than 0.01), but occurred with equal frequency in single preterm and term infants (16% vs 12%). By 5 years of age, metatarsus adductus had resolved in all the term but only in 81% of the preterm children (P less than 0.05). In the preterm and term groups, knee axis (mean intermalleolar distance 22.0 mm vs 20.1 mm), tibial torsion (mean angle -1.2 degrees vs + 0.6 degrees) and angle of gait (mean angle + 1.5 degrees vs + 0.7 degrees) at 5 years were statistically insignificant. Hip function at 5 years was similar in normal preterm and term children but significantly decreased in preterm children with cerebral palsy, more so with regard to abduction (56 degrees vs 39 degrees, P less than 0.05) and extension (22 degrees vs 8 degrees, P less than 0.01). The difference between the sexes was insignificant in both the preterm and term groups.
