“…at the proximal end of the femur makes our approach different from other approaches and techniques because other approaches divide the femur in two parts (either at the subtrochanteric level or trochanteric level) [2,3,12,13,15]. The patient can be placed in either the supine or lateral decubitus position.…”

“…For patients with high dislocation from developmental dysplasia, for revision hip surgery, and for patients with proximal femoral deformities, special procedures and approaches must be used [2,3,14,15]. These approaches must provide good exposure while allowing extremity length equalization, proximal femoral shortening, anatomic cup placement, and soft tissue balance [3,4,12,14,17].…”

We describe a modification of the direct lateral approach to the hip that provides excellent femoral and acetabular exposure and an easy way to shorten the proximal femur and equalize leg length. The approach also is useful for lower extremity elongation while preserving muscle continuity and minimizing postoperative complications. The exact amount of shortening can be calculated and planned preoperatively and measured and corrected intraoperatively if necessary. It avoids the necessity for osteotomies of the trochanter and transverse cuts or detachment of abductor muscles.

“…In restoring the center of hip rotation, the leg may be lengthened by over 4 cm leading to difficulty in reducing the hip and a major risk of neurologic traction injury [7], particularly where there is scarring from previous surgery [15] which increases the risk of direct or indirect neurologic injury [12]. Furthermore, the femoral canal diameter is frequently narrow, which adds to the difficulty of obtaining stable implantation of an adequately sized femoral component [18,25,26,34].…”

Background Total hip arthroplasty (THA) in the presence of developmental dysplasia of the hip (DDH) can be technically challenging. Restoring the anatomic center of hip rotation may require femoral osteotomy. Techniques using cementless components are widely reported but less is known about using cemented components that may be more appropriate with osteopenic bone. Questions/purposes We therefore determined the rate of union, complications, and early functional score in a series of patients with DDH who underwent cemented THA and simultaneous subtrochanteric osteotomy. Methods We retrospectively reviewed 28 patients (35 hips) who underwent a cemented THA for DDH at a mean age of 47.3 years. Two patients (two hips) died within 12 months of surgery of unrelated conditions. The clinical notes and radiographs were reviewed with a minimum followup of 2 years (mean, 5.6 years; range, 2-14 years). Complications were noted. SF-12 and Oxford hip scores (OHS) were recorded for 18 patients preoperatively and after 6 and 12 months. Results Union occurred in 32 of 33 femora (97%); one patient had an infected nonunion. The overall revision rate was 20% (9% femoral revision rate). There were three dislocations, two of which had further surgery. Two patients had a transient neuropraxia. The mean SF-12 physical component score increased from 32 to 52 and mean SF-12 mental component score increased from 48 to 51. The mean OHS decreased from 40 to 27. Conclusion Combined subtrochanteric osteotomy and cemented THA is technically demanding with a higher complication rate than routine THA. The rate of union, complications, implant survival, and early OHS were comparable to those for similar techniques using cementless components.

“…For older patients with fixed scoliosis, the appropriate lengthening is decided by selecting the most comfortable lift height. For the preoperative planning, an anteroposterior radiograph should be taken in an erect position with an appropriate lift under the shorter leg and a plumb line as the vertical reference line (Hoikka et al 1993). As a rule, this view and a lateral radiograph are sufficient for planning the THR.…”
