A key theme of the GIRFT project is centralisation of complex orthopaedic procedures to “Specialist Units” and minimum surgeon volumes. We aimed to estimate the effects of implementing minimum unit and surgeon specific volumes upon orthopaedic units within the Severn region.

Practice profiles for surgeons and units were generated using the NJR Surgeon and Hospital Profile Database. Minimum volume thresholds were set at 13 procedures/year for surgeons and 30 procedures/year for units.

Median surgeon volumes were 33 (range 2–180) for primary TKR, 10 (range 2 – 64) for UKR, 2 (range 2 – 41) for PFJR and 5 (range 2–57) for Revision TKR. Amongst 48 surgeons performing UKR, 26 (54%) performed less than 13 procedures per year accounting for 108 (14%) procedures. Amongst 20 surgeons performing PFJR, 19 (95%) performed <13/year, accounting for 56 (58%) of cases. 49 Surgeons performed revision TKR with 24 (49%) performing <13 revisions per annum, accounting 151 (36%) procedures.

Amongst 16 units performing UKR, 8 (50%) performed <30/year, accounting for 16% overall. Revision TKR was performed in 15 units whilst 8 (53%) performed <30/year, accounting for 62 (15%) cases. We invite discussion of the ramifications of minimum surgeon and unit volumes for Orthopaedic services in the Severn Region.

The Royal College of Surgeons of England (RCS) recently issued guidance regarding the use of re-operation rates in the re-validation of UK based orthopaedic surgeons. Currently, little has been published concerning acceptable rates of re-operation following primary surgical management of orthopaedic trauma, particularly with reference to re-validation.

We conducted a retrospective review of patients undergoing a clearly defined re-operation following primary surgical management of trauma between 1^st January 2010 and 31^st December 2011. 3688 patients underwent primary procedures while 83 (2.25%; 99%CI = 1.69 to 2.96%) required an unplanned re-operation. The mean age of patients was 46 years (range 2–98) with 46 (55%) males and a median time to re-operation of 34 days (IQR 12–134). Potentially avoidable re-operations occurred in 47 patients (56.6%; 99%CI = 42.6 to 69.8%) largely due to technical errors (46 patients; 55.4%; 99%CI = 41.4 to 68.7%), representing 1.27% (99%CI = 0.87 to 1.83%) of the total trauma workload. Within RCS guidelines 28 day re-operation rates for hip fractures, wrist fractures and ankle fractures were 1.4% (99%CI = 0.5 to 3.3%), 3.5% (99%CI = 0.8% to 12.1%) and 2.48% (99%CI = 0.7 to 7.6%) respectively.

We present novel work that has established baseline re-operation rates for index procedures required for revalidation of orthopaedic surgeons.

Background

Evidence concerning the management of dorsal fracture dislocation (DFD) of the proximal interphalangeal joint (PIPJ) in the hand has been limited by small sample size and case heterogeneity within studies. This retrospective case control study examined clinical outcome of this specific subgroup managed by three different methods.

Introduction

Despite the multiple patho-aetiological basis of Hallux valgus (HV), corrective osteotomy is a common and globally performed orthopaedic procedure. Over-correction of the inter-metatarsal angle (IMA), however, is not without consequence. Through increased joint pressures, over-correction may predispose to joint degeneration. Hypothesizing that over-correction leads to an increase in intra-articular joint pressures, we constructed a mechanical simulation of the 1^st metatarsal-phalangeal joint.

Background

Gram stain microscopy is a routinely requested investigation in the evaluation of septic arthritis in both paediatric and adult patients. Recent evidence suggests that gram stain microscopy has poor diagnostic accuracy in adults with a sensitivity of only 45%, however the diagnostic accuracy remains unknown in children. We sought to establish the diagnostic utility of gram stain microscopy in the diagnosis of septic arthritis in children.
