    Abstract:
    PURPOSE: To assess treatment outcomes in adults with neglected femoral neck fractures, and propose a treatment protocol based on bone quality measured by the Singh index. METHODS: 16 men and 6 women aged 18 to 48 (mean, 33) years presented with neglected (>3 weeks old) femoral neck fractures. Those with good bone quality (Singh index, >3) underwent closed reduction and valgus osteotomy and fixation with 120º double angle blade plates (group 1, n=8), whereas those with poor bone quality (Singh index, >3) and/or communition of the posterior femoral neck underwent fibular grafting and internal fixation with one or two 7-mm cannulated cancellous screws (group 2, n=14). Functional outcome was assessed at the 6-month follow-up, according to modified Askin and Bryan criteria. RESULTS: The mean delay in surgery was 12 (range, 4-21) weeks. Patients were followed up for a mean of 19 (range, 12-24) months. The mean time to union was 20 (range, 12-52) weeks. The mean time to full weight bearing was 18 (range, 12-40) weeks. All patients achieved bone union except one in group 1 who had non-union and breakage of the blade plate at week 20 and underwent total hip arthroplasty. Other complications included slippage of fibular graft (n=1), delayed union (n=1), avascular necrosis of the femoral head (n=2), limb length discrepancy (n=3), and superficial infection (n=1). Functional outcome was excellent in 2 patients, good in 17, and poor in 3. CONCLUSION: Valgus osteotomy and double angle blade plate fixation, and fibular grafting and cancellous screw fixation appeared to be appropriate treatments for neglected femoral neck fractures in adults.
