RESUMEN
BACKGROUND: Gap nonunion that may occur following trauma or infection is a challenging problem to treat. The patients with intact or united fibula, preserved sensation in the sole, and adequate vascularity, were managed by tibialization (medialization) of the fibula (Huntington's procedure), to restore continuity of the tibia. The goal of this retrospective analysis study is to report the mid-term results following the Huntington's procedure. MATERIALS AND METHODS: 22 patients (20 males and two females) age 16-34 years with segmental tibial loss more than 6 cm were operated for tibialization of fibula. The procedure was two-staged in seven and single-staged in the rest 15 patients, where the lateral aspect of the leg was relatively supple. In the two-staged procedure, the distal tibiofibular synostosis was performed six-to-eight weeks after the proximal procedure. Weightbearing (protected) was started in a long leg cast after six-to-eight weeks of the second stage and continued for six-to-eight months, followed by the use of a brace. RESULTS: The fibula started showing signs of hypertrophy within the first year after the procedure and it was more than double in breath after the four-year period. Full and unprotected weightbearing on the operated leg was achieved at an average time of 16 months. At the final followup, ten patients were very satisfied, seven satisfied, and five fairly satisfied. One patient had persistent nonunion at the proximal synostotic site even after bone grafting and secondary fixation. CONCLUSION: Huntington's procedure is a safe and simple salvage procedure and remains an excellent option for treating difficult infected nonunion of the tibia in the selected indications.
RESUMEN
BACKGROUND: A high union rate (75%-100%) with a lower incidence of avascular necrosis (8%-9.3%) has been reported with intertrochanteric osteotomy in femoral neck fractures in elderly whereas arthroplasty eliminates the incidence of nonunion and avascular necrosis We present a series of femoral neck fracture in elderly treated with modified Pauwels' intertrochanteric osteotomy and total hip arthroplasty for their functional outcome. MATERIALS AND METHODS: 29 elderly patients of 60 years and above sustaining fresh subcapital femoral neck fracture underwent total hip arthroplasty (group I, n=14) and modified Pauwels' intertrochanteric osteotomy (group II, n=15). Functions were evaluated using modified Harris hip score, d'Aubigne and postel criteria and SF-36 score at 6, 12, 52 and 100 weeks. RESULTS: The fracture union in group II was achieved in 14 (93.3%) patients at the fracture site at an average of 15 weeks and osteotomy united in all patients. Avascular necrosis of the femoral head was observed in one patient (6.7%). Average operative time was 88.9 and 65.6 minutes in group I and II, respectively (P value = 0.00001). An average of 0.8 and 0.2 unit blood was transfused in patients in group I and II, respectively (P value = 0.001). Average time of full weight bearing was 6.1 weeks and 11.6 weeks in group I and group II, respectively. At 100 weeks 71.4% (n = 10) patients in group I and 80% (n = 12) patients in group II showed good to excellent results on the basis of modified Harris hip score. 71.4% (n = 10) patients in group I and 66.6% (n = 10) patients in group II showed good to excellent results on the basis of d'Aubigne criteria. Average SF-36 score was 17.2% in group I and 17.6% in group II. Revision osteotomy was performed in one patient in group II because of implant cut through. Another patient in group II underwent THR because of painful hip. One patient in group I presented with dislocation after 3 weeks of surgery. CONCLUSION: Functional results of total hip arthroplasty and intertrochanteric osteotomy are comparable and the valgus intertrochanteric osteotomy with osteosynthesis in subcapital femoral neck fractures in elderly patients of sixty years and above may be considered as an option.
