Aims

The aim of this study was to compare the pain caused by the application of a tourniquet after exsanguination of the upper limb with that occurring after simple elevation.

Patients and Methods

We used 26 healthy volunteers (52 arms), each of whom acted as their own matched control.

The primary outcome measure was the total pain experienced by each volunteer while the tourniquet was inflated for 20 minutes. This was calculated as the area under the pain curve for each individual subject. Secondary outcomes were pain at each time point; the total pain experienced during the recovery phase; the ability to tolerate the tourniquet and the time for full recovery after deflation of the tourniquet.

The purpose of this study was to compare the outcome and complications of endoscopic versus open release for the treatment of de Quervain’s tenosynovitis. Patients with this condition were randomised to undergo either endoscopic (n = 27) or open release (n = 25). Visual Analogue Scale (VAS) pain and Disabilities of Arm, Shoulder, and Hand (DASH) scores were measured at 12 and 24 weeks after surgery. Scar satisfaction was measured using a VAS scale. The mean pain and DASH scores improved significantly at 12 weeks and 24 weeks (p <  0.001) in both groups. The scores were marginally lower in the endoscopic group compared to the open group at 12 weeks (p = 0.012 and p = 0.002, respectively); however, only the DASH score showed a clinically important difference. There were no differences between the groups at 24 weeks. The mean VAS scar satisfaction score was higher in the endoscopic group at 24 weeks (p < 0.001). Transient superficial radial nerve injury occurred in three patients in the endoscopic group compared with nine in the open release group (p = 0.033).

We conclude that endoscopic release for de Quervain’s tenosynovitis seems to provide earlier improvement after surgery, with fewer superficial radial nerve complications and greater scar satisfaction, when compared with open release.

Objectives

Local corticosteroid infiltration is a common practice of treatment for lateral epicondylitis. In recent studies no statistically significant or clinically relevant results in favour of corticosteroid injections were found. The injection of autologous blood has been reported to be effective for both intermediate and long-term outcomes. It is hypothesised that blood contains growth factors, which induce the healing cascade.

Methods

A total of 60 patients were included in this prospective randomised study: 30 patients received 2 ml autologous blood drawn from contralateral upper limb vein + 1 ml 0.5% bupivacaine, and 30 patients received 2 ml local corticosteroid + 1 ml 0.5% bupivacaine at the lateral epicondyle. Outcome was measured using a pain score and Nirschl staging of lateral epicondylitis. Follow-up was continued for total of six months, with assessment at one week, four weeks, 12 weeks and six months.

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.

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

A suspected fracture of the scaphoid remains difficult to manage despite advances in knowledge and imaging methods. Immobilisation and restriction of activities in a young and active patient must be balanced against the risks of nonunion associated with an undiagnosed and undertreated fracture of the scaphoid.

The assessment of diagnostic tests for a suspected fracture of the scaphoid must take into account two important factors. First, the prevalence of true fractures among suspected fractures is low, which greatly reduces the probability that a positive test will correspond with a true fracture, as false positives are nearly as common as true positives. This situation is accounted for by Bayesian statistics. Secondly, there is no agreed reference standard for a true fracture, which necessitates the need for an alternative method of calculating diagnostic performance characteristics, based upon a statistical method which identifies clinical factors tending to associate (latent classes) in patients with a high probability of fracture.

The most successful diagnostic test to date is MRI, but in low-prevalence situations the positive predictive value of MRI is only 88%, and new data have documented the potential for false positive scans. The best strategy for improving the diagnosis of true fractures among suspected fractures of the scaphoid may well be to develop a clinical prediction rule incorporating a set of demographic and clinical factors which together increase the pre-test probability of a fracture of the scaphoid, in addition to developing increasingly sophisticated radiological tests.

A prospective series of 32 cases with tuberculosis of the hand and wrist is presented. The mean age of the patients was 23.9 years (3 to 65), 12 had bony disease and 20 primarily soft-tissue involvement. The metacarpal of the little finger was the most commonly involved bone. Pain and swelling were the usual presenting features and discharging sinuses were seen in three cases.

All patients were given anti-tubercular chemotherapy with four drugs. Operative treatment in the form of open or arthroscopic debridement, or incision and drainage of abscesses, was performed in those cases where no response was seen after eight weeks of ATT. Hand function was evaluated by the modified score of Green and O’Brien. The mean was 58.3 (25 to 80) before treatment and 90.5 (80 to 95) at the end. The mean follow-up was for 22.4 months (6 to 43). Conservative treatment was successful in 24 patients (75%). Eight who did not respond to chemotherapy within eight weeks required surgery.

Although tuberculosis of hand has a varied presentation, the majority of lesions respond to conservative treatment.

We undertook clinical and ultrasonographic examination of the shoulders of 420 asymptomatic volunteers aged between 50 and 79 years. MRI was performed in selected cases. Full-thickness tears of the rotator cuff were detected in 32 subjects (7.6%). The prevalence increased with age as follows: 50 to 59 years, 2.1%; 60 to 69 years, 5.7%; and 70 to 79 years, 15%. The mean size of the tear was less than 3 cm and tear localisation was limited to the supraspinatus tendon in most cases (78%). The strength of flexion was reduced significantly in the group with tears (p = 0.01).

Asymptomatic tears of the rotator cuff should be regarded as part of the normal ageing process in the elderly but may be less common than hitherto believed.

Locognosia, the ability to localise touch, is one aspect of tactile spatial discrimination which relies on the integrity of peripheral end-organs as well as the somatosensory representation of the surface of the body in the brain. The test presented here is a standardised assessment which uses a protocol for testing locognosia in the zones of the hand supplied by the median and/or ulnar nerves.

The test-retest reliability and discriminant validity were investigated in 39 patients with injuries to the median or ulnar nerve. Intraclass correlation coefficients were used to calculate the test-retest reliability. Discriminant validity was assessed by comparing the injured with the unaffected hand.

Excellent test-retest reliability was demonstrated for the injuries to the median (intraclass correlation coefficient 0.924, 95% confidence interval 0.848 to 1.00) and the ulnar nerves (intraclass correlation coefficient 0.859, 95% confidence interval 0.693 to 1.00). The magnitude of the difference in scores between affected and unaffected hands showed good discriminant validity. For injuries to the median nerve the mean difference was 11.1 points (1 to 33; sd 7.4), which was statistically significant (p < 0.0001, paired t-test) and for those of the ulnar nerve it was 4.75 points (1 to 13.5; sd 3.16), which was also statistically significant (paired t-test, p < 0.0001).

The locognosia test has excellent test-retest reliability, is a valid test of tactile spatial discrimination and should be included in the evaluation of outcome after injury to peripheral nerves.

In a prospective study, we have evaluated the impact of psychological disturbance on symptoms, self-reported disability and the surgical outcome in a series of 110 patients with carpal tunnel syndrome. Self-reported severity of symptoms and disability were assessed using the patient evaluation measure and the Boston carpal tunnel questionnaire. Psychological distress was assessed using the hospital anxiety and depression scale. There was a significant association between psychological disturbance and the pre-operative symptoms and disability. However, there was no significant association between pre-operative psychological disturbance and the outcome of surgery at six months. We concluded that patients with carpal tunnel syndrome should not be denied surgery because of pre-operative psychological disturbance since it does not adversely affect the surgical outcome

Our aim was to determine if a tourniquet placed on the forearm has any advantage in clinical practice over the usual position on the upper arm. We randomised 50 patients who were undergoing an open operation for carpal tunnel syndrome under local anaesthesia into two groups. One had a tourniquet on the upper arm and the other on the forearm. The blood pressure, pulse, and level of pain were recorded at intervals of five minutes during the operation. The surgeons were also asked to evaluate the quality of the anaesthesia, the bloodless field, and the site of the tourniquet. The patients tolerated the tourniquet on the upper arm and forearm equally well. The surgeons had some difficulties when it was placed on the forearm. We therefore recommend placement of a tourniquet on the upper arm for operations on the hand and wrist which are carried out under local anaesthesia

We studied, retrospectively, 131 patients who had undergone an open operation for the carpal tunnel syndrome (CTS) in 229 hands. The symptoms were present on both sides in 59% of patients when first seen. Neurophysiological impairment of the median nerve was observed in 66% of the asymptomatic hands, and 73% of patients in this group developed symptoms of CTS after the opposite side had been operated on. Follow-up of patients with unilateral CTS showed that the subsequent development of disease in the unaffected hand is very common. We conclude that CTS is a bilateral disorder and that it becomes more evident as time passes. There is a correlation between the duration of symptoms and bilateral occurrence

Both idiopathic carpal tunnel syndrome (CTS) and Raynaud’s phenomenon (RP) are common, and may have similar clinical symptoms. The degree of their coexistence is uncertain. We have examined 30 patients, who were diagnosed clinically and electromyographically as having idiopathic CTS, for the presence of RP using a cold provocation test with photoplethysmography. The patients’ hands were exposed in water at 10°C for five minutes. A total of 18 patients (60%) was found to have RP; this is much greater than would be expected from the prevalence in the general population. Raynaud’s phenomenon should be considered when treating patients with CTS because of the possibility of coexistence and the similar symptoms of these two disorders

We studied 58 women of employable age with the carpal tunnel syndrome in order to determine whether the histological appearances of the carpal tunnel, tenosynovium and flexor retinaculum are influenced by work practices. Age, body mass index and the duration of symptoms did not correlate with the extent of oedema or fibrosis within the tenosynovium. The incidence of abnormality on histological examination of the tenosynovium was the same in employed and unemployed patients (p = 1.0), and was not influenced by the level of repetition (p = 0.89) or force (p = 0.29) of work. Myxoid degeneration within the flexor retinaculum was, however, more common in women undertaking ‘high-force’ work. Apart from this finding, the results suggest that work practices do not affect tenosynovial thickening, fibrosis or oedema in patients with carpal tunnel syndrome
