Femoroacetabular impingement (FAI) is the result of abnormal contact/impingement of the femoral head-neck junction and acetabulum during motion. This can be corrected by surgical dislocation (using Ganz's trochanteric osteotomy) and femoral osteochondroplasty +/− acetabular rim resection. Our study aimed to assess the improvement in hip scores following open osteochondroplasty to predict outcomes based on patient characteristics. This was a retrospective case note analysis of a single surgeon case series over a 4 year period. Inclusion criteria were open osteochondroplasty, complete pre- and post-op hip scores available), Tonnis osteoarthritis grade 0 or 1, with 1 year followup. Data was extracted from electronic and paper case notes for pre- and post-op Modified Harris Hip Scores (MHHS), Non-arthritis Hip Scores (NAHS) and SF-12 general satisfaction scores, as well as baseline patient demographics. Two independent observers used the PACS radiology system to examine x-rays and MRI. SPSS version 19 was used for statistical analysis. 42 patients met the inclusion criteria. There was an overall improvement in hip scores after the procedure. Mean pre-op scores were MHHS 52.5, NAHS 44.0, SF-12 32.1. Mean post-op scores were MHHS 66.1, NAHS 58.7, SF-12 36.4. Therefore mean improvements were seen in MHHS (13.6), NAHS (14.7) and SF-12 (4.3), all significant at p<0.005 when paired t-test was used for analysis. Pearson correlation for subgroup analysis showed no significant correlation of scores with age, centre-edge angle or alpha angles. Furthermore, no significant difference was seen between males and females (independent t test). Open osteochondroplasty improves symptoms and function based on patient reported outcome measures. Although the mean scores improved, some patients’ scores deteriorated. We have not identified any statistically significant predictors of outcome, and therefore patient selection remains unclear.
Wrist arthrodesis is a common surgical procedure that provides a high level of functional outcome and pain relief among patients.[1] Upon partial arthrodesis, the wrist experiences changes in load transmission that are influenced by the type of arthrodesis performed. Measuring the load through the wrist joint is difficult, however, combined with computational models [2], it is possible to obtain data regarding the load mechanics of the wrist joint. Although successful fusion rates among patients have been reported, it remains unclear what the biomechanical consequences are. The aim of the study is to quantify pre and post operative load transmission through a cadaveric wrist which has undergone simulated arthrodesis of the radiolunate(RL) joint. An embalmed human wrist was dissected dorsally exposing distal radius, radiocarpal and carpometacarpal joints, and dorsal ligaments. The radioscaphoid(RS) ligament was sacrificed to accommodate insertion of a PPSEN-09375 force sensitive resistor (FSR) into the RS joint. The FSR was calibrated prior to measuring the contact force on the RS joint. The wrist was aligned in the neutral position in cardboard piping, and secured proximally and distally with Dental Plaster (OthoBock Healthcare Plc, Surrey, UK). The midsection of piping was windowed to permit placement of the FSR in the RS joint, and fixation of the RL joint using 2 Kirschner wires. The window was completed circumferentially and the specimen was placed in the Instron where a graduated axial compression was applied at 20 N/min. The results showed that when the radiolunate joint is fused, and a total axial load of 100N is applied, the load transmitted through the RS joint was approx 65N. i.e. 65% of the force. This is greater than the 56% measured experimentally by Blevens et al (1989) in an unfused specimen[3]. We plan to repeat our measurements and compare to an untreated cadaveric wrist.
The Dumfries and Galloway Royal Infirmary (DGRI) catchment area encompasses 5 of the “7 Stanes” mountain bike trails which had approximately 165000 visitors in 2010. Using our hospital coding system we identified potential mountain bike injuries in 2010. Patient postcode, injuries, operating theatre time and number of clinic appointments was recorded. We confirmed mountain bike related hospital admissions in 29 patients. 13 patients had local (DG) postcodes and 16 had non-DG post codes. The DG postcode patients required 41 bed days, 8 operations, 400 minutes theatre time, and 35 DGRI clinic appointments. The non-DG postcodes required 50 bed days, 11 operations, 730 minutes theatre time, 3 DGRI clinic appointments and 8 outpatient referrals to other hospitals. Totals for all postcodes were 91 bed days, 19 operations, 1130 minutes theatre time and 38 DGRI clinic appointments. The surgeries comprised: 2 ankle ORIF; 1 subsequent removal of syndesmosis screw; 5 wrist/forearm manipulations (+/−kwires); 2 distal radius ORIF; 1 DHS; 2 shoulder MUA, 1 calcaneus ORIF, 4 wound debridements, 1 facial wound closure. Other noteworthy admissions were 5 head injuries including 2 cervical spine fractures. We anticipate this is an underestimate and suggest a new code is created to specifically identify mountain bike injuries for A&E and inpatient care. This would allow a more accurate assessment of the impact on all healthcare providers in the county.
Low molecular weight heparin (LMWH) is frequently used as thromboprophylaxis after major orthopaedic surgery. Varying levels of non-adherence (5% to 45%) with outpatient LMWH has been reported. Oral direct thrombin inhibitors have been recommended by industry due to ease of administration. We aim to audit the compliance rate with outpatient LMWH treatment following primary total hip arthroplasties (THA) in our district general hospital (DGH). Using the ORMIS computer system, we identified all primary THA performed in Monklands Hospital between July 2011 and August 2012. Patients’ case notes were analysed retrospectively, looking at operating surgeon's postoperative thromboprophylaxis instructions. We then conducted a telephone interview on patients discharged with outpatient LMWH to assess compliance. There were 58 primary THAs performed during the audit period. 33 patients were discharged on outpatient LMWH, whilst 15 patients and 3 patients were discharged on aspirin and warfarin respectively. Seven patients were excluded as their discharge prescriptions were missing. We successfully contacted 20 of the 33 patients discharged with outpatient LMWH. All respondents showed 100% compliance to the full course of treatment. 50% of patients self-administered; 30% were administered by district nurses and 20% by family members. 35% of patients preferred an oral tablet alternative, for its perceived ease of administration. Bruising and skin irritation were the reported problems in some patients, but these did not affect compliance. Contrary to the previous published non-adherence rates, the compliance rate with outpatient LMWH after THA was high in our DGH. The patient counseling, and family/district nurse involvement in may have contributed to this. However, our numbers of patients are low but data collection continues.
This project began as an audit of performance against the 18-week referral to treatment time (RTT) target but became an interesting development in clinical training. The electronic documents and PACS images for 50 consecutive routine GP referrals to an orthopaedic clinic were traced using the UCPN (Unique Care Pathway Number). The average time from referral to 1st clinic appointment was 57 days (range 29–117). 16 were discharged at 1st visit. 26 were listed for surgery: 20 at the 1st clinic, 3 at the 2nd clinic, 2 at the 3rd clinic, 1 after test results without clinic review. Average time from referral to listing was 68 days (range 28–177). For 25 patients who had surgery, average RTT was 164 days (61–394). 14 patients breached the target. The UCPN allows an overview of the diagnostic work-up for the whole care pathway. Time constraints and less opportunity for continuity of care have hampered effective training in the outpatient clinic. Using the UCPN in this way allows detailed case-based discussions to develop the non-technical surgical skills (NOTSS) of situation awareness and decision-making. In a system where 57 days are typically wasted waiting for a new clinic appointment, clinical reasoning skills must be scalpel sharp to meet the 18-week RTT target. This study hints that better characterising the third of patients discharged and the third directly listed for surgery at the first visit might help with demand management. Better characterising the third of patients needing further tests might allow those test results to be available by the first visit. The next step is to test if, indeed, the UCPN is an effective tool to hone mental dissection.
The Ionising Radiation (Medical Exposure) Regulations 2000 is concerned with: “the making of safety measures in regard to radioactive substances and the emission of ionising radiation”. Responsibility is placed upon the Practitioner, Operator, Referrer and employer. A clinical evaluation of the outcome of each medical exposure must be recorded.” In Ayr Hospital Radiologist report A&E radiographs but not those in fracture clinic unless a specific request was made. Therefore the Surgeon/Trainee must record their interpretation. An audit was completed to review the rate of documentation of the interpretation of radiographs in the clinical records of consecutive patients attending fracture clinics Notes and radiographs were reviewed from 6 separate fracture clinics. 106 patients attended during the time period and were seen by 9 different surgeons; 5 consultants and 4 training grade surgeons. 46 out of 106 patients were x-rayed and interpretation recorded in 38 cases. No interpretation was found in 8 cases, giving an overall compliance of 82.6% with no difference between different grades of surgeon: Consultants 79.2% (19/24); Trainees 86.4% (19/22). These finding were presented at a departmental audit meeting and the audit loop was then closed by a second period of audit with an improvement in the consultants compliance to 100% (22/22) p=0.05 and no significant change in the trainees performance 75% (18/24).
