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. 2011;19(1):13-7 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, Fig. 6), 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.

Melanotic schwannoma (MS) is a rare nerve sheath neuroectodermal neoplasm. We highlight the use of F18-fluorodeoxyglucose positive emission tomography/computed tomography (18F-FDG PET/CT) standardised uptake value (SUV) results in the diagnosis, staging and monitoring of spinal MS. A 58-year-old female patient had a 6-month history of left leg pain (S1) and no skin lesions. Magnetic resonance imaging reported a possible schwannoma with CT-guided biopsy, indicating a metastatic malignant melanoma. 18F-FDG PET/CT scan revealed only sacral destruction and an SUV score of 3.6. Histopathology results confirmed a malignant melanotic peripheral nerve sheath tumour (schwannoma). In MS, the 18F-FDG PET/CT scan SUV cut-off point can be used to distinguish between benign and malignant lesions, whereas (SUVmax) can predict the histologic response and therefore useful as a ‘screening test’. Our case highlights the increased uptake on PET/CT by melanocytic variant of neurogenic tumours and clinicians need to be aware of this.
