Injectable collagenase is an alternative to surgical
treatment for Dupuytren’s disease. Previous studies have reported
on the effectiveness of collagenase in finger contractures. This

Operative release for entrapment of the suprascapular nerve was carried out in 35 patients. They were assessed at an average of 30 months (12 to 98) after operation using the functional shoulder score devised by Constant and Murley. The average age at the time of surgery was 40 years (17 to 67). Entrapment was due to injury in ten patients and no cause was found in three; 34 had diffuse posterolateral shoulder pain. The strength of abduction was reduced in all the patients. The average Constant score, unadjusted for age or gender, before operative release was 47% (28 to 53). In 25 of the patients both the supraspinatus and infraspinatus muscles were atrophied and seven had isolated atrophy of the infraspinatus muscle. The average conduction time from Erb’s point to the supraspinatus muscle and to the infraspinatus muscle was 5.7 ms (2.8 to 12.8) and 7.4 ms (3.4 to 13.4), respectively. In two patients MRI revealed a ganglion in the infraspinatus fossa and, in another, a complete rupture of the rotator cuff. The average time from the onset of symptoms to operation was ten months (3 to 36). A posterior approach was advocated. The average Constant score, after operative release, unadjusted for age or gender was 77% (35 to 91). The overall result was excellent in ten of the patients, very good in seven, good in 14, fair in two, and poor in two. The symptomatic and functional outcome in our series confirmed the usefulness and
We present a review of claims made to the NHS
Litigation Authority (NHSLA) by patients with conditions affecting the
shoulder and elbow, and identify areas of dissatisfaction and potential
improvement. Between 1995 and 2012, the NHSLA recorded 811 claims
related to the shoulder and elbow, 581 of which were settled. This
comprised 364 shoulder (64%), and 217 elbow (36%) claims. A total
of £18.2 million was paid out in settled claims. Overall diagnosis,
mismanagement and intra-operative nerve injury were the most common
reasons for litigation. The highest cost paid out resulted from
claims dealing with incorrect, missed or delayed diagnosis, with
just under £6 million paid out overall. Fractures and dislocations
around the shoulder and elbow were common injuries in this category.
All 11 claims following wrong-site surgery that were settled led
to successful payouts. This study highlights the diagnoses and procedures that need
to be treated with particular vigilance. Having an awareness of
the areas that lead to litigation in shoulder and elbow surgery
will help to reduce inadvertent risks to patients and prevent dissatisfaction
and possible litigation. Cite this article:
Despite the expansion of arthroscopic surgery
of the shoulder, the open deltopectoral approach to the shoulder
is still frequently used, for example in fracture fixation and shoulder
replacement. However, it is sometimes accompanied by unexpected
bleeding. The cephalic vein is the landmark for the deltopectoral
interval, yet its intimate relationship with the deltoid artery,
and the anatomical variations in that structure, have not previously been
documented. In this study the vascular anatomy encountered during 100 consecutive
elective deltopectoral approaches was recorded and the common variants
described. Two common variants of the deltoid artery were encountered.
In type I (71%) it crosses the interval and tunnels into the deltoid
muscle without encountering the cephalic vein. However, in type
II (21%) it crosses the interval, reaches the cephalic vein and
then runs down, medial to and behind it, giving off several small
arterial branches that return back across the interval to the pectoralis
major. Several minor variations were also seen (8%). These variations in the deltoid artery have not previously been
described and may lead to confusion and unexpected bleeding during
this standard anterior surgical approach to the shoulder. Cite this article:
We have examined the accuracy of 143 consecutive ultrasound scans of patients who subsequently underwent shoulder arthroscopy for rotator-cuff disease. All the scans and subsequent surgery were performed by an orthopaedic surgeon using a portable ultrasound scanner in a one-stop clinic. There were 78 full thickness tears which we confirmed by surgery or MRI. Three moderate-size tears were assessed as partial-thickness at ultrasound scan (false negative) giving a sensitivity of 96.2%. One partially torn and two intact cuffs were over-diagnosed as small full-thickness tears by ultrasound scan (false positive) giving a specificity of 95.4%. This gave a positive predictive value of 96.2% and a negative predictive value of 95.4%. Estimation of tear size was more accurate for large and massive tears at 96.5% than for moderate (88.8%) and small tears (91.6%). These results are equivalent to those obtained by several studies undertaken by experienced radiologists. We conclude that ultrasound imaging of the shoulder performed by a sufficiently-trained orthopaedic surgeon is a reliable time-saving practice to identify rotator-cuff integrity.
Between 1998 and 2007, 22 patients with fractures of the scapula had operative treatment more than three weeks after injury. The indications for operation included displaced intra-articular fractures, medialisation of the glenohumeral joint, angular deformity, or displaced double lesions of the superior shoulder suspensory complex. Radiological and functional outcomes were obtained for 16 of 22 patients. Disabilities of the Arm, Shoulder, Hand (DASH) and Short form-36 scores were collected for 14 patients who were operated on after March 2002. The mean delay from injury to surgery was 30 days (21 to 57). The mean follow-up was for 27 months (12 to 72). At the last review the mean DASH score was 14 (0 to 41). Of the 16 patients with follow-up, 13 returned to their previous employment and recreational activities without restrictions. No wound complications, infection or nonunion occurred. Malunion of the scapula can be prevented by surgical treatment of fractures in patients with delayed presentation. Surgery is safe, effective, and gives acceptable functional results.
In a prospective randomised trial of calcifying tendinitis of the rotator cuff, we compared the efficacy of dual treatment sessions delivering 2500 extracorporeal shock waves at either high- or low-energy, via an electromagnetic generator under fluoroscopic guidance. Patients were eligible for the study if they had more than a three-month history of calcifying tendinitis of the rotator cuff, with calcification measuring 10 mm or more in maximum dimension. The primary outcome measure was the change in the Constant and Murley Score. A total of 80 patients were enrolled (40 in each group), and were re-evaluated at a mean of 110 (41 to 255) days after treatment when the increase in Constant and Murley score was significantly greater ( High-energy shock-wave therapy significantly improves symptoms in refractory calcifying tendinitis of the shoulder after three months of follow-up, but the calcific deposit remains unchanged in size in the majority of patients.
Ulnar nerve function, during and after open reduction and internal fixation of fractures of the distal humerus with subperiosteal elevation of the nerve, was assessed by intra-operative neurophysiological monitoring. Intermittent recording of the compound muscle action potentials was taken from the hypothenar muscles in 18 neurologically asymptomatic patients. The mean amplitude of the compound muscle action potential after surgery was 98.1% (
