“…The coverage of the femoral head by the acetabulum measured by the centreedge angle, was significantly better in hips subjected to femoral osteotomy than conservative treatment (Table VI) and this goes with the results reported by most of the authors 11,12,20,21 .…”

This is a prospective study done on 27 hips in 25 patients presented with Perthes' disease between December 1999 and August 2002. Fourteen hips were treated operatively by mean of upper femoral osteotomy (group A), and the other remaining 13 hips were treated conservatively by mean of Scottish Rite abduction brace (group B). All hips were classified preoperatively as Catterall group III and IV, furthermore, two or more "head at risk signs" were seen in all hips with particular emphasis placed on lateral uncovering of the femoral head. Of the 25 patients, 20 (80%) were boys and 5 (20%) were girls, the left side was affected in 18 hips (66.7%), while the right side was involved in 9 hips (33.3%), two patients had bilateral involvement and were encountered in group A. The average time between onset of symptoms and time of treatment for group A and groups B was 9 months and 8.5 months respectively, while the mean duration of follow up was 2.2 years and 1.8 years respectively. It was concluded that group A showed better results than B regarding hip pain (100% vs 15.4%), hip motion (85.7% vs 7.6%), gait (28.5% vs 7.6%), limb-length discrepancies (93.6% vs 30.7%) and centre-edge angle (100% vs 15.4%). Femoral varus derotation osteotomy was found to be the treatment of choice for containment of Perthes' disease with Catterall group III and IV. Both age and sex at the time of the treatment, influences the final outcome, however, longer period of follow-up may allow better final evaluation.

We have performed corrective osteotomies for moderate or severe slipped capital femoral epiphysis (SCFE) using an original blade plate (BP) until 2006 and using a hybrid external fixator (EF) since 2007. We designed a comparative study of the short-term results between BP and EF devices in the treatment of proximal femoral osteotomies in SCFE. Nineteen SCFE patients (12 BP; seven EF) who underwent corrective osteotomies at our institution were included. Clinical and radiographic valuables including the operative time, intraoperative blood loss, postoperative improvement of head shaft angle, and posterior tilting angle, Harris hip score, limb-length discrepancy, and associated complications were compared between the two groups. Although there were no significant differences between the two groups in postoperative improvement of head shaft angle and posterior tilting angle, Harris hip score, and limb-length discrepancy, the EF group showed significantly shorter operative time and less intraoperative blood loss. Serious complications were observed in two patients of the BP group (deep infection and chondrolysis, respectively) and one of the EF group (chondrolysis). Percutaneous proximal femoral osteotomy using an EF appears to be safe, easy, and effective in correcting multiplanar deformities associated with SCFE. It has potential advantages over commonly used open techniques in terms of simplicity and less invasiveness.

“…Several surgical tools have been developed for corrective osteotomies, however, they are mainly focusing on the proximal tibia and femur [16][17][18][19], and scarcely over the humeral supracondyle. Application of computer assisted preoperative planning has been started for decades, and thorough discussions have been reported in other literatures [20][21][22].…”
