Background: Hip fracture is a serious injury mainly affecting the elderly population. The injury has a high mortality of 30% at 1 year and also has a major impact on the quality of life of the survivors. The Scottish Hip Fracture Audit has identified significant difference in the level of care provided in hip fractures between different hospitals and regions. The study aims to assess the impact of the experience of the operating surgeon on the long term outcome of hip fractures taking a cemented bipolar hip arthroplasty as an index procedure.

Materials and Methods: All patients who had the index procedure carried out over an eight year period at the Dumfries and Galloway Royal Infirmary were included in the study. Their preoperative mobility and health status along with the experience of the surgeon performing the procedure were determined. The outcome assessment was carried out using a modified Harris hip score.

Results: 46 patients were followed up at a mean of 45 months (range 16 to 109). One patient required a revision for aseptic loosening. Of the remaining, 18 procedures were carried out by consultant surgeons and 27 by trainees unsupervised. There was no statistical difference in the age, sex, ASA grade, preoperative mobility level or duration of follow up between the two groups of patients. The mean hip score at the time of follow up for the consultant group was 67.2 and 52.6 for the trainee group. This was statistically significant with a P value < 0.05.

Conclusion: The proportion of hip fracture surgeries done by, or under the direct supervision of a consultant orthopaedic surgeon vary widely between various Scottish hospitals (20% to 90%). The significant difference in long term out come of the procedure based on the surgeon’s experience calls for greater supervision and training of juniors.

Background: After Jules-Emile Pean and Neer, unconstrained prosthetic arthroplasty of the shoulder is widely used for glenohumeral osteoarthritis (OA), rheumatoid arthritis (RA) and trauma. While the debate continues over whether humeral head replacement (HHR) or total shoulder arthroplasty (TSR) is better for OA and RA, hemiarthroplasty is preferred in the trauma situation.

Aims: A retrospective review (1993–2000) of 54 patients with the DePuy Global second generation modular shoulder hemiarthroplasty is presented. We highlight the various complications encountered in the longer term and attempt to use our experience to rationalize treatment choice.

Methods: 49 shoulders in 41 patients were available for review. Case records and radiographs were reviewed and clinical assessment carried out. Functional assessment was done using the Constant (CM) and the American Shoulder and Elbow Society systems (ASES). Patients were also asked to complete a shoulder self assessment questionnaire (Insalata, Hospital for Special Surgery).

Results: The pre-op diagnosis was 20 RA, 12 OA, 11 trauma. The mean age was 63.4Yrs. The mean follow up was 6.8Yrs (4–11 Yrs). The mean Constant scores for the 3 groups were 48.1 RA, 46.3 OA, and 56.6 trauma. The mean ASES functional scores were 39.6 RA, 37.5 OA and 32.9 trauma. Active elevation in the RA group was a mean of 83.5°, and 69.5° for OA and 79° for the trauma group. 65% of the RA group was completely pain free compared to 50% and 54% in the OA and trauma groups respectively. Patient satisfaction was high in the RA and OA groups but poor in the trauma group. 90% of RA patients had evidence of superior migration of the prosthesis (ASM), with the majority of them developing cuff dysfunction. 36% of trauma patients had tuberosity escape/nonunion. 100% of OA patients developed late glenoid erosion. Presence of secondary glenoid arthrosis and ASM co-related with poor function (r =0.5, p< 0.05).

Discussion. Second generation prosthesis can prejudice the shoulder biomechanics. Over-tensioning the joint can lead to both glenoid wear and cuff rupture.

In OA patients, satisfaction was highest, but function was poor. Patients with out cuff tear pre-operatively did not develop it later. They may thus benefit from a TSR compared to HHR. RA patients had the least pain, best function and high satisfaction. Most had evidence of either primary or secondary cuff dysfunction. In them patients HHR may be the preferred option. Trauma patients did poorly in all respects. More anatomical reconstruction and greater emphasis on salvage of the humeral head is required in this group.
