    Leg length inequality (LLI) following total hip replacement is a complication which features increasingly in the recent literature. The definition of LLI is complicated by lack of consensus regarding radiological measurement, clinical measurement and the incomplete relationship between LLI and associated symptoms. This paper reviews 79 reports relating to LLI post hip replacement, detailing definitions and classification and highlighting patient populations prone to symptomatic LLI. While there is no universal definition of LLI, there is a broad consensus that less than 10 mm of difference on AP view plain radiographs is clinically acceptable. There are few techniques described that consistently produce a postoperative LLI of less than this magnitude. Where postoperative LLI exists, lengthening appears to cause more problems than shortening. In cases of mild LLI, non-surgical management produces adequate outcomes in the majority of cases, with functional LLI cases doing better than those with true LLI. Operative correction is effective in half of cases, even where nerve palsy is present, and remains an important option of last resort. Poor outcomes in patients with LLI may be minimised if individuals at risk are identified and counselled appropriately

    Metaphyseal tantalum cones in primary total knee arthroplasty and their functional outcome is described using 3 case reports over 6 years. 3 knees in 3 individuals (mean age of 70.4 years) were operated on. Ambulation with walking frame was achieved from post-operation day 1, with weight-bearing as tolerated. Mean range of motion was 122° and Mean Knee Society Score was 88. All showed improvement in pre-operative limb alignment. Radiological fracture union was achieved on an average of 3 months. All were independent ambulators and pain-free at the latest follow-up. Our case series shows that tantalum cones are associated with significant improvements in clinical scores, patient symptoms, range of movement, early weight-bearing and low rates of complications in complex proximal tibial fractures with poor bone stock
