Carpal tunnel decompression in patients with normal nerve conduction studies.

Some patients present with typical clinical features of carpal tunnel syndrome despite normal nerve conduction studies. This study compared the preoperative and 1-year postoperative QuickDASH scores in patients with normal and abnormal nerve conduction studies, who underwent carpal tunnel decompression. Of the 637 patients included in the study, 19 had clinical features of carpal tunnel syndrome but normal nerve conduction studies, and underwent decompression after failure of conservative management. Preoperative QuickDASH scores were comparable in both groups (58 vs 54.8). However, there were significant differences between the normal and abnormal nerve conduction study groups in the QuickDASH at 1 year (34.9 vs 21.5) and change in QuickDASH postoperatively (23.1 vs 33.4). Patients with normal nerve conduction studies had comparable preoperative disability scores compared with those with abnormal studies. Although they had a significant improvement in QuickDASH at 1 year, this was significantly less than those with abnormal nerve conduction studies. Level of evidence: III.

Long-Term Follow-up of Arthrodesis vs Total Joint Arthroplasty for Hallux Rigidus.

BACKGROUND: The optimal operative management of hallux rigidus is still a matter for debate among surgeons. Despite arthrodesis widely considered to be the gold standard treatment, many surgeons advocate arthroplasty as a suitable alternative. There are, however, few long-term or high-quality studies evaluating these modalities. We present the 15-year follow-up of a randomized controlled trial. METHODS: This data is the follow-up to the original study published in 2005. In the original study, 63 patients (77 toes) were recruited to and randomized to have either metatarsophalangeal joint (MTPJ) arthrodesis or arthroplasty. The primary outcome measure was a decrease in pain on a visual analog scale (VAS) at 24 months. In the present study, data were available for all surviving patients (52 patients, 66 toes). Data were collected in the form of satisfaction scores, VAS for pain, the VAS foot and ankle and survivorship data. RESULTS: The results of the original study demonstrated that pain relief was greater following arthrodesis at 2 years. At 15 years, patients with an arthrodesis experienced less pain and were more satisfied compared to those with an arthroplasty. No functional differences were seen between these 2 groups. There were more revisions in the arthroplasty group. CONCLUSION: Despite the hope of better function, less pain, and greater satisfaction from MTPJ replacement, this was not found in our patient population. The long-term results of our study showed that arthrodesis outperformed arthroplasty. If an arthroplasty failed, then salvage was likely to be technically difficult, with significant potential for complications. LEVEL OF EVIDENCE: Level I, randomized controlled trial.

A Cross-sectional Study of Current Doctors' Performance in a Modified Version of a Medical School Admission Aptitude Test: The UKCAT.

The 2-hour long United Kingdom Clinical Aptitude Test (UKCAT) is used by many universities in the United Kingdom as part of their selection process for undergraduate medical and dentistry degrees. We aimed to compare the performance of senior doctors in primary and secondary care and across a range of specialties, in a modified version of the medical school entrance examination-the mUKCAT. Lay people were also included in the study. Despite its widespread use, this is the first study that examines the performance of senior clinicians in the UKCAT.The study used a prospective cross-sectional design. It used mock questions from the UKCAT website to generate an mUKCAT that was anticipated to take 15 minutes to complete. In all, 167 doctors at consultant, general practitioner (GP), or specialty trainee grade and 26 lay people took part.The overall mean mUKCAT score of all participants was 2486 (69.1%). Of the total cohort, 126 (65.3%) scored above our designated threshold of 2368 and were deemed to have passed the mUKCAT. Excluding lay people, 113 (67.7%) of the 167 doctors scored above that threshold. Medical specialty was associated with overall score (P = 0.003), with anesthetists/intensive care physicians scoring highest (n = 20, mean score 2660) and GPs scoring lowest (n = 38, mean score 2302). Academics outperformed nonacademics (mean score of academics, n = 44 vs nonacademics, n = 123: 2750 vs 2406; P < 0.001). Those clinicians in senior management positions scored lower than those in "standard" roles (mean score of senior management, n = 31 vs standard roles, n = 136: 2332 vs 2534, mean difference 202, 95% confidence interval 67-337, P = 0.004).In the situational judgement section, there was no evidence that specialty was associated with score (P = 0.15). Academics exhibited greater situational judgement than their nonacademic colleagues (academics vs nonacademics: 69.8 vs 63.6%; P = 0.01).The majority of senior clinicians passed our mUKCAT. Academics and anesthetists were found to be the best performers, with GPs and those in senior management positions performing the worst.

An unusual complication after shoulder hemiarthroplasty.

Hemiarthroplasty of the shoulder can be a safe and an effective treatment for pain in patients with rheumatoid arthritis. Many complications have been previously described in the literature; the most common of which are dislocation, loosening, periprosthetic fractures, and infection. We report a patient who presented with a discharging sinus over the tip of the acromium which was created by the displacement of the prosthesis and erosion of the AC joint and distal clavicle. The erosion of the distal clavicle and AC joint caused the remaining proximal clavicle to become mobile and displaced posteriorly; this spike of clavicle was then able to penetrate the trapezius muscle and eventually the skin causing an aseptic sinus. This was successfully treated with the exploration and excision of the distal 2 cm of the clavicle.
