Colonna capsular arthroplasty represents an option for the management of chronic hip dislocation in young patients with dysplasia. In the appropriate patient, modern capsular arthroplasty procedures may provide an opportunity for hip preservation in patients with preserved femoral head cartilage and not appropriate for total hip arthroplasty. Here, we review our experience with surgical disloca...

This study examined the impact of using elasticized compression shorts on performance measures and proprioception at the hip. Thirteen healthy subjects completed 2 randomized testing sessions-one while wearing the Coreshorts compression shorts and one while not wearing the shorts. During each trial, active range of motion at the hip; joint angle replication during hip flexion, abduction, and hy...

Thirty-five total hip arthroplasties (33 patients) were performed in cases of Crowe grade III or IV hip dysplasia using subtrochanteric shortening osteotomy with two kinds of femoral stem: monoblock and modular type. All acetabular components were used with a cementless cup. The average patient age was 47.8 years, and the average follow-up time was 5.1 years. Acetabular reconstruction was perfo...

Developmental dysplasia of the hip [DDH] is a common condition of the childhood, affecting 1.6 to 28.5 newborns per 1000 live births [1]. Treatment is age dependent, progressing from abduction splinting with nonrigid or semirigid braces to closed reduction with hip spica cast and finally to open surgical procedures. Pavlik harness is a nonrigid brace widely accepted to treat infants younger tha...

PURPOSE Non-compliance with foot abduction bracing in children with clubfeet treated with the Ponseti method is the leading risk factor for deformity recurrence. A dynamic foot abduction orthosis is believed to result in improved compliance, fewer skin complications, and fewer recurrences. A case-control trial was conducted to test this hypothesis. METHODS A prospective cohort of children wit...

[Purpose] This study investigated the selective activation of the gluteus maximus during a prone hip extension with knee flexion exercise, with the hip joint in different positions. [Subjects] The subjects were 21 healthy, male volunteers. [Methods] Activities of the right gluteus maximus, right hamstrings, bilateral lumbar erector spinae, and bilateral lumbar multifidus were measured using sur...

[Purpose] This study investigated the effect of hip position on muscle onset time during prone hip extension with knee flexion. [Subjects] The study included 21 healthy male volunteers. [Methods] Muscle onset times of the right gluteus maximus, right hamstrings, bilateral lumbar erector spinae, and bilateral lumbar multifidus were measured using surface electromyography during right hip extensi...

Recurrent clubfoot deformity after successful initial correction with the use of the Ponseti method continues to be a common problem and is often caused by noncompliance with wear of the traditional foot abduction brace. The purpose of this study was to assess the results of a newly designed dynamic foot abduction orthosis in terms of (1) parental compliance and (2) effectiveness in preventing ...

BACKGROUND A hip brace, the WISH-type S-form brace, improved hip function scores markedly in patients with painful hip osteoarthritis (OA). To evaluate the biomechanical effects of the brace, gait analysis using a force plate was performed. METHODS For the gait of seven patients with this hip brace, characteristic parameters calculated from three-dimensional (i.e., vertical, forward, and medi...
