“…One patient had implant failure and needed revision. The results of our study are quite comparable to other studies [20][21][22] done about this procedure. In the study by Agarwal et al, [20] the number of patients was 30, the average time taken for union was 13 weeks, and the Modified Harris hip score was excellent in 73.33% cases, good result 16.67% and poor in 10% of cases, which compares quite favourably to our study.…”

“…Use of a DHS allows controlled dynamic collapse at the fracture site, and counteracts the shear forces and varus displacement; however, it does not resist rotation during insertion, which can be managed using a de-rotational screw. [21] In our study, some, but not all, intracapsular fractures required the use of a de-rotational screw, probably owing to callus formation at the fracture site. Several authors have described valgus osteotomy and DHS xation.…”

BackgroundFemoral cervicotrochanteric fracture fixation failure often requires a salvage procedure to preserve the hip. To understand its limitations, this study investigated the use of intertrochanteric osteotomy for this purpose and analyzed causes of failure.MethodsDuring 2001 − 2017, 21 patients (males:females = 12:9; 47 ± 17 years) with failed femur cervicotrochanteric fracture fixation were treated with intertrochanteric osteotomy. All patients were followed-up using functional assessment according to the Harris hip score (HHS) and radiological assessment. The clinical end-point was conversion to hip arthroplasty for any reason or acquiring a symptomatic hip with a HHS < 80.ResultsWith a follow-up duration of 124 ± 63 months, success was achieved in 16 patients, whereas 5 patients developed fixation failure. Early failure was associated with fixation loss in 2 hips with subcapital fractures, while late failure was related to progression of pre-existing osteonecrosis of the femoral head (ONFH) in 3 hips. Aside from the 2 early failure hips, the osteotomy healed uneventfully in all cases, and the original fracture sites healed within 17.2 ± 6.3 weeks. Of the 5 hips converted to arthroplasty, standard femoral implants were used without the need to re-perform an osteotomy to align the medullary canal. At the final follow-up, significant improvements in limb-length discrepancy (LLD), neck-shaft angle (NSA), and HHS were observed. The valgus osteotomy angle for correction was 21.9° ± 8.4°, and this was maintained at 21.1° ± 10.5° during follow-up.ConclusionsIntertrochanteric osteotomy is a useful operation and can promote fracture-healing in cases of failed cervicotrochanteric fracture fixation. Subcapital fracture with limited bone to enable secure purchase of the fixation device and pre-existing ONFH were associated with high failure rates. In such cases, salvage should not be attempted using this procedure alone, and arthroplasty or other salvage procedures may be necessary.
