Three fatal cases of infections that followed total joint replacement are repoarted, in each of which a hematogenous source of infection was identified. There also were five non-fatal cases presumable arising hematogenously which were reported in the literature. It is emphasized that concomitant disease, including active rheumatoid arthritis, may predispose to this complication.

Recent reports have suggested a relationship between release of lower-extremity contractures and the development of hypertension in cerebral palsy and poliomyelitis patients. A retrospective study was performed on 119 cerebral palsy patients who had undergone lower-extremity contracture releases. Temporary elevation of systolic blood pressure in the perioperative and intraoperative periods occurred in 46 patients (39%), and temporary elevation of diastolic blood pressure occurred in 14 patients (12%). Type of cerebral palsy, patient age, patient sex, type of anesthesia, and type of procedure were not significantly correlated with the temporary blood pressure elevations. No patient developed sustained elevation of systolic and diastolic blood pressure. We conclude that lower-extremity contracture release in pediatric patients is not associated with an increased incidence of postoperative hypertension.
OBJECTIVE: To determine the prevalence of musculoskeletal and neurological complications of adults with pediatric-onset spinal cord injuries (SCI), and their association with demographic, impairment, and functional limitation factors. METHOD: Structured interview including standardized measures. PARTICIPANTS: Individuals who sustained SCI at < or = age 18 years and were > or = age 24 years at interview. OUTCOME MEASURES: Prevalence of musculoskeletal and neurological complications: fractures during the past 3 years; scoliosis; heterotopic ossification; hip dislocation or contractures; ankle contractures or pain; shoulder pain; elbow contractures or pain; pain at other sites; neurological deterioration; syringomyelia; and spasticity since injury. RESULTS: The 216 individuals who were interviewed had mean age at injury of 14 years and mean age at follow-up of 29 years. Most common complications were pain at any site (69%), spasticity (57%), shoulder pain (48%), scoliosis (40%), hip contractures (23%), and back pain (22%). There were no statistically significant associations between gender and the complications. Whites were more likely than nonwhites to experience pain. Younger age at injury was significantly associated with scoliosis and hip subluxation, and older age at injury was associated with ankle pain and spasticity. Older age at follow-up and longer duration of injury were both associated with elbow and shoulder pain, fractures, and neurological deterioration. Longer injury duration was also associated with hip subluxation and scoliosis. Ankle pain, elbow contractures, and spasticity were more common in those with tetraplegia, and hip contractures were associated with paraplegia. American Spinal Injury Association motor scores were significantly lower in those with elbow contractures and spasticity, and significantly higher in those with hip contractures and neurological deterioration. CONCLUSION: Musculoskeletal and neurological complications are common sequelae among adults with pediatric-onset SCI. Demographic, impairment, and functional limitation factors are associated with these complications and can identify at-risk individuals.
Internal rotation gait is common in children with cerebral palsy. Factors thought to contribute include femoral anteversion, hip flexor tightness, imbalance of hip rotators, and hamstring and adductor tightness. The exact cause of internal rotation must be defined before contemplating surgery. We investigated the prevalence of internal hip rotation and associated factors, which are considered to influence this walking pattern, in patients with cerebral palsy. Gait laboratory data of 222 patients with cerebral palsy were studied retrospectively. Two groups were selected; those with maximum dynamic hip internal rotation of more than 27 degrees and those with less than 20 degrees. Of 222 patients, 27.0% (diplegia, 61.7%; hemiplegia, 38.3%) had at least one hip with dynamic internal rotation of more than 27 degrees. This study suggests that dynamic hip internal rotation is multifactorial in origin. The most significant differences in clinical measures were found in values of passive hip external rotation range, femoral anteversion and hip flexor contracture. We discuss the role of early treatment of hip flexion contracture.

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.
A case of bilateral groin pain of sudden onset in a 14-yr-old boy is presented. The patient reported sudden onset of pain in both inguinal regions during a 100-m dash. He presented a week later to the clinic where physical examination revealed a shuffling gait, bilateral hip flexion contractures, limited active and passive hip extension, and bilateral weakness of hip flexion and knee extension. Plain radiographs of the pelvis revealed avulsion fragments minimally displaced from both anterior inferior iliac spines (AIIS). Pain relief in the acute phase was achieved by limiting ambulation until weight bearing was painless. The patient was treated conservatively and returned to full speed running in 10 wk. Only one case of bilateral AIIS avulsion fractures has previously been reported. AIIS avulsion fractures that are not widely displaced may be treated conservatively. Following a careful program of rehabilitation, full functional recovery following AIIS avulsion fractures may be achieved in 4-6 wk.
The fate of 89 patients with meningomyelocele operated at the Institute of Orthopedics and Rehabilitation in Poznań between 1970 and 1989 due to paretic deformities of lower extremities has been traced by the authors. Deformities prevented nursing, standing or ambulating; their type and results of treatment have been related to the level of neurosegmental lesion. Modified Sharrard's classification served to group the patients. The level of lesion established during lower extremities muscles testing has been verified after neurological examination supplemented with electrophysiological tests: sensory response within L3-S2 dermatomes, afferent conduction velocity of the peroneal nerve and selected muscles of lower extremity electromyogram. Deformities due to inadequate nursing (hip and knee contractures and equinus foot) were the main obstacle in the rehabilitation in patients with spinal Th12-L2 lesion. In patients with L3-L5 lesion hip contractures were accompanied by dislocation or subluxation of the hip due to muscular imbalance. Knee contracture was less frequent in this group and foot deformities were diverse. Surgical correction of paretic deformity of the hip was the last stage of management designed to promote rehabilitation, following previous foot and knee surgery. In patients with Th12-L2 lesion recurrence of contractures made standing and walking impossible. In patients with L3-L5 neurosegmental lesion surgery for paretic dislocation or subluxation of the hip inclusive of open reduction, varus-derotation osteotomy of the proximal femur, transiliac osteotomy and iliopsoas transfer to the greater trochanter according to Mustard resulted in stable hip. Seventy percent of patients with L3-L4 lesion and all patients with L5 lesion profited from hip surgery with reduced orthotic use and effective gait.
Release of static and dynamic contractures around the hip provides significant immediate benefits for the patient and accelerates postoperative rehabilitation. Knee pain is decreased, groin pain is eliminated, range of motion of the hip is increased, and functional leg-length difference is reduced. This article emphasizes the importance of techniques used to ensure soft tissue balance.
Seventeen patients with cerebral palsy (29 hips) underwent psoas recession at the pelvic brim. The operative technique was a direct anterior approach, lateral to the femoral sheath. There were no infections or nerve or arterial injuries. After surgery, clinical examination revealed that fixed hip-flexion contractures decreased significantly in all patients. All of the subjects retained the ability to flex the hip against gravity and against manual resistance. All of the subjects underwent pre- and postoperative gait analysis. Stance-phase dynamic minimum hip flexion decreased significantly. Dynamic pelvic tilt improved to a statistically significant level for the younger children but did not for the group as a whole. There was less improvement with increasing age. Step length was significantly increased and cadence significantly decreased in all patients. We conclude that psoas recession at the pelvic brim, by using the anterior approach, lateral to the femoral sheath, is a safe, reliable, and effective procedure for children with cerebral palsy who have excessive anterior pelvic tilt and excessive dynamic hip flexion or hip-flexion contracture.
