Observational StudyIs it time to revisit the AO classification of fractures of the distal radius? Inter- and intra-observer reliability of the AO classification.
We conducted an observational radiographic study to determine the inter- and intra-observer reliability of the AO classification of fractures of the distal radius. Plain posteroanterior and lateral radiographs of 456 patients with an acute fracture of the distal radius were classified by a consultant orthopaedic hand specialist and two specialist trainees, and the k coefficient for the inter- and intra-observer reliability of the type, group and subgroup classification was calculated. ⋯ The inclusion of 'group' and 'subgroup' into the classification reduced the inter-observer reliability to fair (kgroup 0.29, ksubgroup = 0.28) and the intra-observer reliability to moderate (kgroup 0.53, ksubgroup 0.49). Disagreement was found to arise between specific subgroups, which may be amenable to clarification.

Randomized Controlled TrialNo effect of the infiltration of local anaesthetic for total hip arthroplasty using an anterior approach: a randomised placebo controlled trial.
Only limited data are available regarding the infiltration of local anaesthetic for total hip arthroplasty (THA), and no studies were performed for THA using the anterior approach. In this prospective, randomised placebo-controlled study we investigated the effect of both standard and reverse infiltration of local anaesthetic in combination with the anterior approach for THA. The primary endpoint was the mean numeric rating score for pain four hours post-operatively. ⋯ There were significantly more side effects at one and eight hours post-operatively in the placebo group (p = 0.02; p = 0.03), but this did not influence the mobilisation of the patients. There were no differences in all other outcomes between the groups. We found no clinically relevant effect when the infiltration of local anaesthetic with ropivacaine and epinephrine was used in a multimodal pain protocol for THA using the anterior approach.

Multicenter StudyThe vascularised fibular graft for limb salvage after bone tumour surgery: a multicentre study.
Vascularised fibular grafts (VFGs ) are a valuable surgical technique in limb salvage after resection of a tumour. The primary objective of this multicentre study was to assess the risk factors for failure and complications for using a VFG after resection of a tumour. The study involved 74 consecutive patients (45 men and 29 women with mean age of 23 years (1 to 64) from four tertiary centres for orthopaedic oncology who underwent reconstruction using a VFG after resection of a tumour between 1996 and 2011. ⋯ VFG is a successful and durable technique for reconstruction of a defect in bone after resection of a tumour, but is accompanied by a significant risk of complications, that often require revision surgery. Union was not markedly influenced by the need for chemo- or radiotherapy, but should not be expected during chemotherapy. Therefore, restricted weight-bearing within this period is advocated.

Comparative StudyPatient-reported outcomes after total and unicompartmental knee arthroplasty: a study of 14,076 matched patients from the National Joint Registry for England and Wales.
Whether to use total or unicompartmental knee replacement (TKA/UKA) for end-stage knee osteoarthritis remains controversial. Although UKA results in a faster recovery, lower rates of morbidity and mortality and fewer complications, the long-term revision rate is substantially higher than that for TKA. The effect of each intervention on patient-reported outcome remains unclear. ⋯ Complications and readmission are more likely after TKA. Although the data presented reflect the short-term outcome, they suggest that the high revision rate for UKA may not be because of poorer clinical outcomes. These factors should inform decision-making in patients eligible for either procedure.

The medial column Synthes Midfoot Fusion Bolt is associated with unacceptable rates of failure in corrective fusion for Charcot deformity: Results from a consecutive case series.
Charcot neuro-osteoarthropathy (CN) of the midfoot presents a major reconstructive challenge for the foot and ankle surgeon. The Synthes 6 mm Midfoot Fusion Bolt is both designed and recommended for patients who have a deformity of the medial column of the foot due to CN. We present the results from the first nine patients (ten feet) on which we attempted to perform fusion of the medial column using this bolt. ⋯ Four of these feet have undergone a revision procedure, with good radiological evidence of fusion. The medial column bolt provided satisfactory correction of the deformity but failed to provide adequate fixation for fusion in CN deformities in the foot. In its present form, we cannot recommend the routine use of this bolt.
