Diabetes mellitus is recognised as a risk factor for carpal tunnel syndrome. The response to treatment is unclear, and may be poorer than in non-diabetic patients. Previous randomised studies of interventions for carpal tunnel syndrome have specifically excluded diabetic patients. The aim of this study was to investigate the epidemiology of carpal tunnel syndrome in diabetic patients, and compare the outcome of carpal tunnel decompression with non-diabetic patients. The primary endpoint was improvement in the QuickDASH score. The prevalence of diabetes mellitus was 11.3% (176 of 1564). Diabetic patients were more likely to have severe neurophysiological findings at presentation. Patients with diabetes had poorer QuickDASH scores at one year post-operatively (p = 0.028), although the mean difference was lower than the minimal clinically important difference for this score. After controlling for underlying differences in age and gender, there was no difference between groups in the magnitude of improvement after decompression (p = 0.481). Patients with diabetes mellitus can therefore be expected to enjoy a similar improvement in function

There is conflicting evidence about the functional outcome and rate of satisfaction of super-elderly patients (≥ 80 years of age) after carpal tunnel decompression. We compiled outcome data for 756 patients who underwent a carpal tunnel decompression over an eight-year study period, 97 of whom were super-elderly, and 659 patients who formed a younger control group (< 80 years old). There was no significant difference between the super-elderly patients and the younger control group in terms of functional outcome according to the mean (0 to 100) QuickDASH score (adjusted mean difference at one year 1.8; 95% confidence interval (CI) -3.4 to 7.0) and satisfaction rate (odds ratio (OR) 0.78; 95% CI 0.34 to 1.58). Super-elderly patients were, however, more likely to have thenar muscle atrophy at presentation (OR 9.2, 95% CI 5.8 to 14.6). When nerve conduction studies were obtained, super-elderly patients were more likely to have a severe conduction deficit (OR 12.4, 95% CI 3.0 to 51.3). Super-elderly patients report functional outcome and satisfaction rates equal to those of their younger counterparts. They are more likely to have thenar muscle atrophy and a severe nerve conduction deficit at presentation, and may therefore warrant earlier decompression.

We present the electromyographic (EMG) results ten years after open decompression of the median nerve at the wrist and compare them with the clinical and functional outcomes as judged by Levine’s Questionnaire. This retrospective study evaluated 115 patients who had undergone carpal tunnel decompression at a mean of 10.47 years (9.24 to 11.36) previously. A positive EMG diagnosis was found in 77 patients (67%), including those who were asymptomatic at ten years. It is necessary to include both clinical and functional results as well as electromyographic testing in the long-term evaluation of patients who have undergone carpal tunnel decompression particularly in those in whom revision surgery is being considered. In doubtful cases or when there are differing outcomes, self-administered scales such as Levine’s Questionnaire should prevail over EMG results when deciding on the need for revision surgery

The April 2015 Wrist & Hand Roundup360 looks at: Non-operative hand fracture management; From the sublime to the ridiculous?; A novel approach to carpal tunnel decompression; Osteoporosis and functional scores in the distal radius; Ulnar variance and force distribution; Tourniquets in carpal tunnel under the spotlight; Scaphoid fractures reclassified; Osteoporosis and distal radial fracture fixation; PROMISing results in the upper limb

A variation of the motor branch of the median nerve is described in which this branch arose more proximally and pierced the flexor retinaculum. Its significance during a carpal tunnel decompression is pointed out

Children with a mucopolysaccharidosis or mucolipidosis suffer progressive disability of the hands, particularly in relation to dysfunction of the median nerve. This is an increasing problem because bone-marrow transplantation has dramatically improved survival without apparently changing the musculoskeletal manifestations. We have reviewed 48 children with these syndromes who required carpal tunnel decompression, recording symptoms, signs, radiological, electrophysiological and operative findings, histology and upper-limb function. In these children the carpal tunnel syndrome differs from that seen in adults. Symptoms are rare but signs such as decreased sweating, pulp atrophy, thenar wasting and manual clumsiness are much more common. At operation, the flexor retinaculum was thickened and a mass of white tenosynovium engulfed the flexor tendons. Most patients had some definite nerve constriction with a thickened epineurium. Functional improvement was seen after early decompression, with some benefit from simultaneous tendon release. Regular physiotherapy helped to maintain increased hand movement. We describe our assessment protocol, the physiotherapy and operative regime and the standard functional review which helps to maximise function in the hands and upper limbs of these children

We investigated the response of chronic neck and shoulder pain to decompression of the carpal tunnel in 38 patients with whiplash injury. We also determined the plasma levels of substance P (SP) and calcitonin gene-related peptide (CGRP), which are inflammatory peptides that sensitise nociceptors. Compared with normal control subjects, the mean concentrations of SP (220 v 28 ng/l; p < 0.0001) and CGRP (400 v 85 ng/l; p < 0.0005) were high in patients with chronic shoulder and neck pain before surgery. After operation their levels fell to normal. There was resolution of neurological symptoms with improvement of pain in 90% of patients. Only two of the 30 with chronic neck and shoulder pain who had been treated conservatively showed improvement when followed up at two years. In spite of having neuropathic pain arising from the median nerve, all these patients had normal electromyographic and nerve-conduction studies. Chronic pain in whiplash injury may be caused by ‘atypical’ carpal tunnel syndrome and responds favourably to surgery which is indicated in patients with neck, shoulder and arm pain but not in those with mild symptoms in the hand. Previously, the presence of persistent neurological symptoms has been accepted as a sign of a poor outcome after a whiplash injury, but our study suggests that it may be possible to treat chronic pain by carpal tunnel decompression

Dupuytren’s disease is a chronic inflammatory process which produces contractures of the fingers. The nodules present in Dupuytren’s tissue contain inflammatory cells, mainly lymphocytes and macrophages. These express a common integrin known as VLA4. The corresponding binding ligands to VLA4 are vascular cell adhesion molecule-1 (VCAM-1) present on the endothelial cells and the CS1 sequence of the fibronectin present in the extracellular matrix. Transforming growth factor-beta (TGF-ß) is a peptide hormone which has a crucial role in the process of fibrosis. We studied tissue from 20 patients with Dupuytren’s disease, four samples of normal palmar fascia from patients undergoing carpal tunnel decompression and tissue from ten patients who had received perinodular injections of depomedrone into the palm five days before operation. The distribution of VLA4, VCAM-1, CS1 fibronectin and TGF-ß was shown by immunohistochemistry using an alkaline phosphorylase method for light microscopy. In untreated Dupuytren’s tissue CS1 fibronectin stained positively around the endothelial cells of blood vessels and also around the surrounding myofibroblasts, principally at the periphery of many of the active areas of the Dupuytren’s nodule. VCAM-1 stained very positively for the endothelial cells of blood vessels surrounding and penetrating the areas of high nodular activity. VCAM-1 was more rarely expressed outside the blood vessels. VLA4 was expressed by inflammatory cells principally in and around the blood vessels expressing VCAM-1 and CS1 but also on some cells spreading into the nodule. TGF-ß stained positively around the inflammatory cells principally at the perivascular periphery of nodules. These cells often showed VLA4 expression and co-localised with areas of strong production of CS1 fibronectin. Normal palmar fascia contained only scanty amounts of CS1 fibronectin, almost no VCAM-1 and only an occasional cell staining positively for VLA4 or TGF-ß. In the steroid-treated group, VCAM-1 expression was downregulated in the endothelium of perinodular blood vessels and only occasional inflammatory cell expression remained. Expression of CS1 fibronectin was also much reduced but still occurred in the blood vessels and around the myofibroblast stroma. VLA4-expressing cells were also reduced in numbers. A similar but reduced distribution of production of TGF-ß was also noted. Our findings show that adherence of inflammatory cells to the endothelial wall and the extravasation into the periphery of the nodule may be affected by steroids, which reduce expression of VCAM-1 in vivo. This indicates that therapeutic intervention to prevent the recommencement of the chronic inflammatory process and subsequent fibrosis necessitating further surgery may be possible

Aims

We introduced a self-care pathway for minimally displaced distal radius fractures, which involved the patient being discharged from a Virtual Fracture Clinic (VFC) without a physical review and being provided with written instructions on how to remove their own cast or splint at home, plus advice on exercises and return to function.

Aims

Displaced distal radius fractures were investigated at a level 1 major trauma centre during the COVID-19 2020 lockdown due to the implementation of temporary changes in practice. The primary aim was to establish if follow-up at one week in place of the 72-hour British Orthopaedic Association Standards for Trauma & Orthopaedics (BOAST) guidance was safe following manipulation under anaesthetic. A parallel adaptation during lockdown was the non-expectation of Bier’s block. The secondary aim was to compare clinical outcomes with respect to block type.

Aims

The aim of this study was to compare the efficacy of a corticosteroid injection for the treatment of carpal tunnel syndrome (CTS) in patients with and without Raynaud’s phenomenon.

Aims

The primary aim of this study was to describe patient satisfaction and health-related quality of life (HRQoL) following corrective osteotomy for a symptomatic malunion of the distal radius.

Aims

Plate and screw fixation has been the standard treatment for painful conditions of the wrist in non-rheumatoid patients in recent decades. We investigated the complications, re-operations, and final outcome in a consecutive series of patients who underwent wrist arthrodesis for non-inflammatory arthritis.

Aims

To evaluate safety outcomes and patient satisfaction of the re-introduction of elective orthopaedic surgery on ‘green’ (non-COVID-19) sites during the COVID-19 pandemic.
