We aimed to analyse the clinical outcomes and survivorship of anatomic total shoulder arthroplasty using a stemless humeral component with cemented pegged polyethylene glenoid performed with the technique of eccentric reaming to partially correct retroversion. These results were then compared with TSA using the same implant for end-stage shoulder arthritis with a normal version of the native glenoid. A retrospective case series was performed using a prospectively collected database of anatomic TSA patients operated at Woodend General Hospital, Aberdeen, UK. Between 2010 and 2019, 107 total shoulder arthroplasties (TSA) were done using standard anatomic stemless TSA implants (Affinis Short, Mathys Ltd, Bettlach, Switzerland) in 98 patients. Standardized preoperative and postoperative shoulder radiological imaging for glenoid retroversion was collected. Depending on the angle of native glenoid version, patients were divided into retroverted and non-retroverted glenoid as per the Walch Classification. To assess the radiological outcome at the final follow-up, radiolucency was assessed on the glenoid and humeral side using the Lazarus grading. The final clinical and radiologic outcome from the retroverted group was compared with the population with a non-retroverted glenoid. Five TSAs were excluded from the analysis as they did not have satisfactory postoperative radiographs. Hence, a total of 102 shoulders were available for analysis.Objective
Design and methods
Excessive glenoid retroversion and posterior wear leads to technical challenges when performing anatomic shoulder replacement. Various techniques have been described to correct glenoid version, including eccentric reaming, bone graft, posterior augmentation and custom prosthesis. Clinical outcomes and survivorship of a Stemless humeral component with cemented pegged polyethylene glenoid with eccentric reaming to partially correct retroversion are presented. Between 2010– 2019, 115 Mathys Affinis Stemless Shoulder Replacements were performed. 50 patients with significant posterior wear and retroversion (Walch type B1, B2, B3 and C) were identified. Measurement of Pre-operative glenoid retroversion and Glenoid component version on a post op axillary view was performed by method as described by Matsen FA. Relative correction was correlated with clinical and radiological outcome.Abstract
Aim
Patients and Methods
The purpose of this study was to compare outcome of arthroscopic stabilization of the shoulder using knotted and knotless anchors and two rehabilitation regimes. This is a retrospective study of 58 patients who underwent arthroscopic shoulder stabilization over a five year period (2005–2009). There were two groups of patients. In group A stabilization was performed using absorbable anchors with a knotted technique using No.1 PDS suture. This group had an early mobilization regime. In group B a knotless anchor technique was used with PEEK anchors and nonabsorbable sutures. The patients in this group were immobilised in a sling for 6 weeks. There were a total of 58 patients, 37 in group A and 21 in group B. The mean age of patients undergoing the procedure was 35.7. There were a total of 23 males and 14 females in group A and 15 males and 6 females in group B. The number of dislocations prior to surgery ranged from 0 to multiple times a day. Patients had a mean follow up of 5 years (three to seven years - 2005 to 2009) and subjective shoulder function was evaluated using Oxford instability score and self-assessment questionnaire.Objective
Method
The administration of prophylactic antibiotics is essential in the prevention of surgical site infection, particularly when metalwork is implanted. Intravenous Cefuroxime has been the antibiotic of choice for prophylaxis in our unit over the last few years. Unfortunately this has been linked to an increased rate of Clostridium Difficile infection. Our departmental antibiotic prophylaxis guidelines, based on the Scottish Intercollegiate Guidelines Network (SIGN), were therefore revised, such that intravenous Flucloxacillin and Gentamicin became the first line agents. We primarily aimed to assess whether prophylactic antibiotics were being administered according to our revised local guidelines. Steps were then taken to improve adherence to the guidelines, and the audit repeated. Data was collected prospectively between 1st November 2010 and 28th November 2010 (cycle 1). Demographic data, type of surgery, details of choice, dose and timing of antibiotic administration were compiled. The quality of documentation was also reviewed. Interventions to improve adherence to the guidelines were commenced between 1st January 2011 and 28th February 2011. This included a departmental presentation, supplementary distribution of the guidelines and email communication to all orthopaedic surgeons and anaesthetists to increase awareness. A repeat audit cycle was performed between 1st March 2011 and 28th March 2011 (cycle 2). All data was stored and statistically analysed using SPSS for Windows 17.0. A total of 130 patients were included, with 65 patients in each cycle. Demographic data and type of surgery were reasonably similar in both cycles. Intravenous antibiotics, when required, were administered within 30 minutes of the surgical incision in most cases in both cycles of the audit. In the first cycle of the audit only 9 out of 65 patients (14%) received the correct antibiotics as suggested by our updated guidelines. This improved significantly to 46 out of 57 patients (81%) in the second cycle. Documentation of antibiotic prescribing in the anaesthetic record, operation note and drug charts also improved in the second cycle. We observed poor initial adherence to our updated guidelines as most patients received incorrect antibiotic prophylaxis. However, following our audit interventions to increase awareness of the new guidelines, we witnessed a significant improvement in compliance. Our next step will be to ensure that the new policy of using intravenous Flucloxacillin and Gentamicin does indeed reduce the rate of Clostridium Difficile infection while maintaining a low rate of deep and superficial wound infection.
Late presentation and rapid progression of Dupuytren's contracture significantly increases operating time, complications and likelihood of incomplete correction; however, surgical timing is usually more a function of waiting list length than of clinical criteria. We sought to measure the rate of progress of Dupuytren's contracture. All patients with Dupuytren's contracture referred to the sole Consultant Hand Surgeon for Highland Region between June 1997 and February 2003 were prospectively included. Fixed flexion deformities at each finger joint and thumb-index angle to the point of firm resistance to extension were recorded by a single observer (QGNC) at presentation and immediately pre-operatively. Of 151 participants 37% had a family history. There was a male predominance of 5:1, with bilaterality in 77% at presentation. Five percent had diabetes, 3% had epilepsy, 52% acknowledged tobacco habits and 24% regular alcohol in excess of recommended limits. Angular deterioration was observed in 52% of digits, over one quarter of this occurred at the small finger joints, where 58% of PIPJs progressed. Mean delay from presentation to surgery was 11 months (2-55.5). Mean age at presentation of 62 (16-86) years did not correlate with angular deformity at presentation or with velocity of deterioration or with manual/non-manual employment. Mean severity of deformity at presentation for manual (34°) was double non-manual workers (17°) although angular deterioration was faster in the non-manual group (3.8 cf 0.7°/month respectively). Similar speeds of deterioration were seen at MCPJ and PIPJ, speed of deterioration was 2.2°/month for each of the three ulnar digits. Speed of deterioration correlated (r=0.7) with severity of deformity at presentation for ring and small fingers. This study offers the first quantification of rate of deterioration in Dupuytren's contracture. This could be used as a waiting list tool to predict the delay before a digit is likely to pose increased surgical risk.
