SUMMARY Perioperative halo traction was used in the treatment of severe scoliosis in 19 children. Diagnoses included neuromuscular, idiopathic, and congenital scoliosis. Traction was transferable between the bed and a walker or wheelchair. Thirteen patients had prior spinal surgery, and most required osteotomy. Traction was used for 6 to 21 weeks. All(More)
BACKGROUND While early spinal fusion may halt progressive deformity in young children with scoliosis, it does not facilitate lung growth and, in certain children, it can result in thoracic insufficiency syndrome. The purpose of this study was to determine pulmonary function at intermediate-term follow-up in patients with scoliosis who underwent thoracic(More)
Thirty-two patients who had medial open reduction of 40 hips were reviewed at an average of 10.3 years follow-up (range 2.5-18.6 y). Center-edge angles and acetabular indices were measured on preoperative, postoperative, and final radiographs. The presence of AVN was noted. The final radiograph was assigned a Severin grade. One hip re-dislocated. Eight(More)
BACKGROUND Many studies have demonstrated that orthotic treatment is effective for the prevention of curve progression in patients with adolescent idiopathic scoliosis. However, the effect of being overweight on the outcome of orthotic treatment has not been reported. The purpose of the present study was to determine whether orthotic treatment of adolescent(More)
BACKGROUND In the treatment of idiopathic clubfeet, the Ponseti method and the French functional method have been successful in reducing the need for surgery. The purpose of this prospective study was to compare the results of these two methods at one institution. METHODS Patients under three months of age with previously untreated idiopathic clubfeet(More)
Twenty-three children who had unilateral surgery for idiopathic clubfeet underwent gait analysis and isokinetic muscle-strength testing at an average of 10 years after surgical release. Ankle sagittal-plane kinematics were disturbed in 20 clubfeet. Fifteen children had an internal foot-progression angle. Genu valgum and knee hyperextension were common.(More)
Ninety children between the ages of 2 and 3 years with 127 clubfeet underwent gait analysis. Fifty-one feet had undergone posteromedial releases, 52 feet had no surgery following correction of the deformity using the French physical therapy program, and 24 feet had either tendo Achilles lengthening or posterior releases following physical therapy.(More)
PURPOSE Friedreich's ataxia is a genetically transmitted, progressive spinocerebellar degenerative disease characterized by ataxia. The purpose of this study is to evaluate the demographics, progression, nonoperative, and operative treatment of spinal deformities in patients with Friedreich's ataxia at 2 tertiary pediatric orthopaedic hospitals. METHODS(More)
BACKGROUND Early-onset scoliosis, when left untreated, leads to severe deformity. Until the last decade, treatment of progressive curves in young children often consisted of definitive spinal fusion. The recognition of thoracic insufficiency syndrome associated with definitive early fusion has led to the development of new surgical techniques developed to(More)
