We sought to establish whether carpal and cubital tunnel syndrome requiring surgery is associated with deprivation in England. Data from 10,496 adult patients who were treated in our hand unit over a 20-year period were reviewed. The Index of Multiple Deprivation was used to measure deprivation from the patients' postcode. The mean age at surgery in the most deprived three quintiles was significantly lower than in the least deprived two quintiles for carpal tunnel release (55 vs 59 years, respectively) and cubital tunnel release (52 vs 57 years, respectively). The incidence rate was significantly lower for the three least deprived quintiles when compared with the most deprived quintile for both conditions. The incidence rate ratio of the least deprived quintile compared with the most deprived quintile for carpal tunnel release was 0.70 for men and 0.76 for women. The incidence rate ratio of the least deprived quintile compared with the most deprived quintile for cubital tunnel release was 0.79 for men and 0.49 for women. Carpal tunnel and cubital tunnel syndrome requiring surgery is more common in deprived patients and occurs at an earlier age. Level of evidence: IV.

Introduction: We integrated two factors, demographic population shifts and changes in prevalence of disease, to predict future trends in demand for hand surgery in England, to facilitate workforce planning., Methods: We analysed Hospital Episode Statistics data for Dupuytren's disease, carpal tunnel syndrome, cubital tunnel syndrome, and trigger finger from 1998 to 2011. Using linear regression, we estimated trends in both diagnosis and surgery until 2030. We integrated this regression with age specific population data from the Office for National Statistics in order to estimate how this will contribute to a change in workload over time., Results: There has been a significant increase in both absolute numbers of diagnoses and surgery for all four conditions. Combined with future population data, we calculate that the total operative burden for these four conditions will increase from 87,582 in 2011 to 170,166 (95% confidence interval 144,517-195,353) in 2030., Discussion: The prevalence of these diseases in the ageing population, and increasing prevalence of predisposing factors such as obesity and diabetes, may account for the predicted increase in workload. The most cost effective treatments must be sought, which requires high quality clinical trials. Our methodology can be applied to other sub-specialties to help anticipate the need for future service provision., (Copyright © 2014 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

This article presents the history of the discovery of compression of the median nerve in the carpal tunnel without an identifiable cause as a distinct clinical entity. By analyzing primary sources, we show that, at the beginning of the twentieth century, physicians described patients with paresthesias and numbness in the hands, most prominent at night, accompanied by bilateral symmetrical atrophy along the radial side of thenar eminence. At the time, the 2 most influential hypotheses regarding etiology were, first, compression of the lower trunk of the brachial plexus by a cervical or first rib, and second, compression of the thenar branch of the median nerve as it passes beneath the anterior annular ligament of the wrist. The condition was named syndrome of partial thenar atrophy and was considered a distinct clinical entity. In 1946, after extensive analysis, neurologist Walter Russell Brain concluded that both sensory and motor symptoms of the syndrome were caused by "compression neuritis" of the median nerve in the carpal tunnel. At his suggestion, surgeon Arthur Dickson Wright performed decompression of the nerve by "an incision of the carpal ligament," with excellent results. Brain presented this work at the Royal Society of Medicine in London in 1946 and published his landmark paper in Lancet the following year. In so doing, he established the basis for the disease we know today as idiopathic carpal tunnel syndrome. Unfortunately, in 1947, Brain did not realize that another "condition" with the same clinical picture but without atrophy of the thenar muscles, known as acroparesthesia at the time, was actually the same disease as syndrome of partial thenar atrophy, but of lesser severity. As a result of Brain's influence, 7 other papers were published by 1950. Between 1946 and 1950, there were at least 10 papers that presented, in total, 31 patients (26 women) who exhibited symptoms of compression of the median nerve without an identifiable cause and underwent section of the transverse carpal ligament., (Copyright © 2014 American Society for Surgery of the Hand.

Chronic hemodialysis patients are susceptible to median nerve compression. The clinical symptoms, surgical results and prognosis of chronic hemodialysis-related carpal tunnel syndrome have different results from those of idiopathic carpal tunnel syndrome. The aim of this study was to evaluate the clinical results of extended open carpal tunnel release in chronic hemodialysis-related carpal tunnel syndrome. A review of 31 open-extended carpal tunnel decompressions in 27 chronic dialysis patients was performed. The surgical technique is detailed and the clinical results analyzed. There was an improvement in symptoms and strength in all patients. There were no instances of recurrence of nerve compression during the one year follow-up period. Extended open carpal tunnel decompression improves symptoms and enhances hand function in patients receiving chronic hemodialysis.

Introduction: Carpal tunnel decompression is the most commonly performed surgical procedure within a hand unit. Although very effective, the complications following the procedure can be significant. In an attempt to identify the causes of such complications, we assessed whether seniority of the surgeon impacts on outcome for open carpal tunnel decompression., Patients and Methods: Data were jointly and prospectively gathered from two units from either side of the Atlantic - the Pulvertaft Hand Center, UK and the Curtis Hand Center, USA. The aim of the study was to assess outcome following carpal tunnel decompression. Completed data were gathered following open carpal tunnel decompression on 352 hands. Surgeons of a consultant grade had performed 123 of these procedures whilst surgical trainees had performed 229 of the procedures. Assessment was by Levine Katz questionnaire results, Semmes-Weinstein testing, grip strength and pinch grip strength testing performed both pre-operatively and 6 months' postoperatively. Complications following the procedure were also recorded., Results: Mean results were found to be better in those patients where the surgeon was of a consultant grade. However, this was only found to be of statistical significance on Semmes-Weinstein testing. Complications following the procedure were also noted to be higher in the group of patients operated on by trainee grades., Conclusions: Our results show the carpal tunnel decompression performed by a surgeon of consultant grade offers slightly better results in objective neurological testing when compared with those performed by a more junior grade.

Introduction: Two prospective audits of activity in a hand unit were performed, in 1989-1990 and during 2000-2001, to identify trends in elective hand surgery referrals from primary care., Patients and Methods: Two 6-month prospective audits of activity in a hand unit were performed, including elective referrals from primary care. Data were collected on all in-district referrals with elective hand disorders. Cross boundary flow was identified to permit assessment of changes in referrals by diagnosis over a decade., Results: There was a 36% increase in health authority referrals for elective hand surgery over the decade (from 289 to 392 per 100,000 of population per year). The number of elective hand surgery operations rose 34% over the decade (from 149 to 199 operations per 100,000 of population per year). Carpal tunnel syndrome (the commonest reason for elective referral) almost doubled (from 59.7 to 112 per 100,000 of population per year). Referrals for ganglion, the second most common elective referral, rose modestly. Referrals for osteoarthritis (commonly basal thumb arthritis) almost trebled over the decade to become the fourth commonest condition referred to the hand unit (from 12.7 to 34 per 100,000 of population per year). Referrals for Dupuytrens disease, trigger finger and rheumatoid arthritis were relatively unchanged over the decade. Congenital hand referrals are uncommon but doubled during the decade., Conclusions: Hand surgery referrals rose by 36% over the decade. Analysis of the commoner conditions referred reveal a high prevalence within the community with the possibility of increased referrals in years to come.

Objective: There is insufficient evidence regarding the clinical and cost-effectiveness of surgical interventions for carpal tunnel syndrome. This study evaluates the cost, effectiveness and cost-effectiveness of minimally invasive surgery compared with conventional open surgery., Patients and Methods: 194 sufferers (208 hands) of carpal tunnel syndrome were randomly assigned to each treatment option. A self-administered questionnaire assessed the severity of patients' symptoms and functional status pre- and postoperatively. Treatment costs were estimated from resource use and hospital financial data., Results: Minimally invasive carpal tunnel decompression is marginally more effective than open surgery in terms of functional status, but not significantly so. Little improvement in symptom severity was recorded for either intervention. Minimally invasive surgery was found to be significantly more costly than open surgery. The incremental cost effectiveness ratio for functional status was estimated to be 197 UK pounds, such that a one percentage point improvement in functioning costs 197 UK pounds when using the minimally invasive technique., Conclusions: Minimally invasive carpal tunnel decompression appears to be more effective but more costly. Initial analysis suggests that the additional expense for such a small improvement in function and no improvement in symptoms would not be regarded as value-for-money, such that minimally invasive carpal tunnel release is unlikely to be considered a cost-effective alternative to the traditional open surgery procedure.
