Objective evaluations of resident performance can be difficult to simulate. A novel competency based surgical OSCE was developed to evaluate surgical skill. The goal of this study was to test the construct validity comparing previously validated Ottawa scores (O-scores) and Orthopaedic in-training evaluation scores (OITE).

An OSCE designed to simulate typical general orthopaedic surgical cases was developed to evaluate resident surgical performance. Post-graduate year (PGY) 3–5 trainees have an encounter (interview and physical exam) with a standardized patient and perform a correlating surgery on a cadaver. Examiners evaluate all components of the treatment plan and provide an overall score on the OSCE and also provide an O-score on overall surgical performance. Convergent and divergent validity was assessed comparing OSCE scores to O-scores and OITE scores. SPSS was used for statistical analysis. ANOVA was used to compare PGY averages and Pearson correlation coefficients were calculated to compare OSCE versus O-score and OITE scores.

A total of 96 simulated surgical cases were evaluated over a 3 year period for 24 trainees. There was a significant difference in OSCE scores based on year of training. (PGY3 − 6.06/15, PGY4 − 8.16/15 and PGY5 − 11.14/15, p < 0 .001). OSCE and O-scores demonstrated a strong positive correlation of +0.89 while OSCE and OITE scores demonstrated a moderate positive correlation of 0.68.

OSCE scores demonstrated strong convergent and moderate divergent correlation. A positive trajectory based on level of training and stronger correlations with established, validated scores supports the construct validity of the novel surgical OSCE.

It is well recognised that patients with diabetes mellitus have a predisposition towards stenosing flexor tenosynovitis (FTS). However, recent research has suggested an association between the development of FTS and haemoglobin A1c (HbA1c) level which is used as a marker of glycaemic control. National guidelines on management of diabetes suggest treatment should aim to maintain HbA1c at <6.5%.

The aim of our study is to quantify glycaemic control in patients undergoing surgical A1 pulley release.

We retrospectively reviewed the blood results of 78 patients who underwent FTS surgery. 27 of these had an HbA1c checked within 6 months of their surgery and we therefore presumed these patients were diabetic. For diabetic patients the average HbA1c was 7.9% (range 5.3–11.4) and only 7 of the 27 patients had an HbA1c within the recommended range.

In this cohort 33% of patients were presumed diabetic and 74% of these had a documented HbA1c above the national target suggesting a significant number presenting for surgery have poor glycaemic control. Therefore it may be of benefit to screen for this in patients undergoing FTS surgery.

Post-operative pain is well recognised in patients undergoing shoulder surgery. With the recent advances in arthroscopic shoulder surgery over the last decade, a larger number of cases are being performed in day surgery units. These procedures are generally performed under general anaesthetic with either an interscalene or suprascapular nerve block or local anaesthetic infiltration.

The aim of our prospective audit was to investigate the adequacy of analgesia provided for patients, undergoing day case arthroscopic shoulder procedures in a rural district general hospital, to ensure best medical care and to tailor certain procedures to appropriate analgesic pathways in the future.

Fifty consecutive patients, who underwent day case arthroscopic shoulder surgery, were contacted by telephone one week post surgery, to assess their post-operative pain scores and analgesic requirements.

Patients who received a nerve block were found to have a significantly longer duration of pain relief (p < 0.001). These patients also had significantly less pain performing their usual activities of daily living in the immediate post-operative period (p = 0.05), compared to patients who only had local anaesthetic infiltration. There was no trend found between the type of procedure and post-operative pain scores.

Our audit has confirmed that nerve blocks provide longer pain relief, but has also highlighted the need to take into consideration pre-operative pain and pain perception to enable analgesia to be tailored.

Surgical reconstruction of the injured Anterior Cruciate Ligament (ACL) is an effective solution to knee instability, but not all grafts incorporate well. The biological environment in the knee that controls graft integration is not well understood, and this study aims to fill that gap as the first step towards a translational approach to optimise outcomes.

Over two stages, tissue samples and knee fluid samples were harvested from patients undergoing ACL reconstruction. These samples were cultured and stored to allow batch analysis for a variety of cytokines, growth factors and collagenases.

Stage 1 (n=14) identified the presence of specific pro-inflammatory cytokines, growth factors and latent collagenase. Information gathered allowed a more targeted approach to be used in stage 2 (n=18). Stage 2 data from tissue cultures suggest that collagenase activity peaks later than 6 hours post-op. The relationships between collagenase activity and levels of TNF-alpha, IL-1beta and bFGF are of potential interest, and the profiles of patients will be compared with longer term follow-up data to determine any effects on outcomes.

Further detailed assessment of the biology of ACL graft incorporation is required, but these preliminary data have clarified some of the details worthy of further study.
