Residual Femoral Deformity and Femoroacetabular Impingement after Intertrochanteric Osteotomy for Slipped Capital Femoral Epiphysis.

چکیده
We retrospectively reviewed 29 hips in which intertrochanteric osteotomies were performed for severe slipped capital femoral epiphyses. Mean age at surgery: 12.6 years. Mean follow-up period: 6 years. At the final follow-up evaluation, one patient had coxalgia, and six hips showed a limited range of motion. A pistol-grip deformity was observed in 13 hips, osteoarthritis in two hips, and a bump existed in 19 hips on the latest radiographs. Gradual remodeling of the bumps was observed post-operatively in 22 hips. The mean α and β angles and offset α and β improved over time. The remodeling proceeded rapidly for 1 year post-surgery. We compared hips classified as β angles of ≥ 63° to < 63° at the final follow-up evaluation, the mean β angle 1 year post-surgery, and the mean ratio of improvement of the β angle per year from 1 year post-surgery to the final follow up, which differed significantly. Nearly all of the patients who underwent intertrochanteric osteotomies had residual morphologic abnormalities, but few had clinical symptoms. The β angle 1 year post-surgery and the ratio of remodeling of the bump from 1 year post-surgery to the final follow-up can be regarded as a potential predictor of morphologic results after intertrochanteric osteotomy.

Subtrochanteric osteotomy effectively treats femoroacetabular impingement after slipped capital femoral epiphysis.
UNLABELLED Femoroacetabular impingement causing pain and deformity often follows in situ pinning for severe, stable (Grade III) slipped capital femoral epiphysis. We asked whether a transverse percutaneous subtrochanteric osteotomy using external fixation could decrease pain, restore function and motion, and improve radiographic outcome. We performed a transverse subtrochanteric osteotomy with ...
متن کاملRemodeling of Cam Deformity in Slipped Capital Femoral Epiphysis
INTRODUCTION There has been growing interest in the concept of cam-type femoroacetabular impingement (FAI) as an etiological factor in the development of osteoarthritis of the hip after slipped capital femoral epiphysis (SCFE). Remodeling of the femoral head has been reported from several authors, however, a little is known about the remodeling from the point of cam deformity. Therefore, we con...
متن کاملThe results of downgrading moderate and severe slipped capital femoral epiphysis by an early Imhauser femur osteotomy
PURPOSE Patients with moderate and severe slipped capital femoral epiphysis (SCFE) develop osteoarthritis earlier in life in association with mechanical impingement. METHODS To correct deformity and diminish impingement, we performed epiphysiodesis combined with an Imhauser intertrochanteric osteotomy (ITO) in moderate and severe slipped capital femoral epiphysis. We downgraded the angle of t...
متن کاملRadiological evidence of femoroacetabular impingement in mild slipped capital femoral epiphysis: a mean follow-up of 14.4 years after pinning in situ.
Conventional treatment of mild slipped capital femoral epiphysis consists of fixation in situ with wires or screws. Recent contributions to the literature suggest that even a mild slip may lead to early damage of the acetabular labrum and adjacent cartilage by abutment of a prominent femoral metaphysis. It has been suggested that the appropriate treatment in mild slipped capital femoral epiphys...
متن کاملSlipped capital femoral epiphysis: a review of management in the hip impingement era
Slipped capital femoral epiphysis (SCFE) remains the most common adolescent hip disorder. Most cases present with stable slips, and in situ fixation is the most commonly adopted treatment worldwide. The introduction of the concept of femoroacetabular impingement and subsequent studies have revealed SCFE-related hip impingement to be a significant pre-arthritic condition, and the previously sugg...
