    For evaluating pelvic support osteotomy as a salvage procedure in managing neglected hip problems in adolescents and young adults, PSO was performed for 20 hips in 20 patients (5 men and 15 women). The mean age was 21.5 years. The etiology was neglected developmental dysplasia of the hip in 9 patients, post-septic hip sequelae in 9 patients, and paralytic dislocation due to poliomyelitis in 2 patients. All patients were treated by two osteotomies: a proximal femoral osteotomy to support the pelvis and correct the flexion and rotational deformities of the hip and a distal varization and lengthening osteotomy. Final clinical evaluation was done 6 months after frame removal. The mean external fixation time was 6.4. Lengthening and mechanical axis parallelism was achieved in all patients. At the final follow-up and according to a predesigned scoring system, there were 7(35%) excellent results, 6(30%) good results, 7(35%) fair results, and no poor results. Hip reconstruction by Ilizarov’s concept can be technically demanding and involving lengthy period wearing the frame but found to be a valuable salvage procedure for numerous neglected hip problems particularly in young patients

    The new “dual osteotomy”: combined open wedge and tibial tuberosity anteriorisation osteotomies

    The high frequency with which medial compartment osteoarthritis is associated with patellofemoral osteoarthritis makes the addition of tibial tuberosity anteriorisation to high tibial osteotomy an appealing solution, despite the discouraging previously reported long-term results when tubercle anteriorisation was combined with a Coventry closed wedge technique. We conducted a prospective study of a new osteotomy combination: “the dual osteotomy”. An open wedge high tibial osteotomy was combined with 1- to 1.5-cm Maquet-like tibial tuberosity anteriorisation. Thirty-four knees in 30 patients underwent surgery, including ten knees in nine male patients and 24 knees in 21 female patients with a mean age of 45 years (age range 34−58 years). All patients had varus medial compartment osteoarthritis and patellofemoral osteoarthritis with preoperative anatomical tibiofemoral angle exceeding 5°. Twenty-four months after surgery, final evaluation detected improvement in the Knee Society clinical rating system function score from a mean of 61.3 (range 30−80) preoperatively to a mean of 87.3 (range 50−100) postoperatively and in the knee pain score from 27.3 (range 10−30) to 47 (range 30−50) postoperatively. Based on the rating system, at final follow-up, 70% of patients experienced no pain, 13% had mild or occasional pain, 10% had pain on stairs only, and 7% had pain during walking and on stairs. Anatomical tibiofemoral angles from 0 to 10° valgus were achieved in 91% of operated knees, and union was achieved in all cases within six to twelve weeks after surgery. The dual osteotomy was effective in the short term in cases of medial compartment osteoarthritis associated with patellofemoral osteoarthritis
