Arthroplasty of the shoulder is a common procedure. Although there are many studies of the results of individual arthroplasty concepts, there is little published on the results of all shoulder replacements (with no exclusions) from a single centre.

We analysed 120 elective shoulder replacements in 106 patients performed over a 5 year period in our unit. 77 were female and average age was 70 years. 85 procedures were for osteoarthritis, 10 cuff arthropathy, 8 post-traumatic arthritis. 65 patients underwent a resurfacing hemiarthroplasty, 25 stemmed hemiarthroplasty and 30 had total shoulder replacements (5 reverse polarity). Mean follow up was 1.6 years.

There was a move away from resurfacing hemiarthroplasty towards stemmed total shoulder replacement over the study period.

The overall incidence of complications was 25.8%, 19.2% occurring within 12 months of surgery: 4 replacements dislocated, there were 5 periprosthetic fractures, 2 patients developed deep infection (treated by debridement), 2 patients aseptic loosening, 11 developed subacromial/biceps pain and 2 had glenoid erosions. The overall revision rate was 5.8%, the re-operation rate 10%.

The complication and re-operation rate in our unit is comparable with individual arthroplasty studies and may be useful as a reference for audits in centres across the UK.

There has been a trend towards operative management of pelvic injuries. Posterior pelvic integrity is more important for functional recovery. Percutaneous iliosacral screw fixation is being increasingly preferred for posterior pelvic stabilisation. Outcome reporting for this procedure remains inconsistent and un-standardised.

Retrospectively, all percutaneous iliosacral screw fixations done at this institute during a 5-year period (2008–2012) were reviewed. 28 patients, who had had at least 12 months follow-up, were contacted and clinical scoring was done by postal correspondence. Radiographs were measured for displacements and leg-length discrepancy. Possible factorial associations and correlations were investigated.

Mean Majeed score was 83 (median 87), mean EQ-Visual Analog Score (EQ-VAS) was 75.5 (median 80) and the two scores were correlated with statistical significance. Tile AO type C injuries produced worse outcomes and patients who'd anterior pelvic fixation did better.

Our results show high patient-reported outcomes, excellent radiologically measured reductions and unions. The incidence of complications is very low. There is a significant correlation between the EQ-VAS arm of the EQ5D instrument and the Majeed score in this patient population. Incidence of non-pelvic surgical procedures in these patients was significantly associated with worse outcomes. Leg length discrepancies appeared to increase after patients were fully weight bearing.
