Applying appropriate upper limb regional-specific and joint-specific tools along with suitable psychologic tools provides an effective assessment of supportive, interventional, and treatment strategies in TE. Tennis elbow (TE) is a painful pathologic condition with its origin in the common wrist extensor muscles at the lateral epicondyle. As the second most frequently diagnosed musculoskeletal disorder in the neck and upper limb in a primary care setting, with an annual incidence of 4 to 7 cases per 1000 patients in general practice (with a peak at 35 to 54 yrs of age), TE has considerable socioeconomic costs. As pain relief and improvement in functional performance are the 2 common aims of all treatment strategies, the importance of using appropriate tools for the assessment of pain and functional disability in TE is evident. In view of the high prevalence of TE, uncertainties about its treatment, and its substantial socioeconomic consequences, using more specific, patient-centred assessment tools is essential for providing more useful information on the level of pain and functional disability in TE. The Study aimed to: 1) compare pain and functional disability in tennis elbow (TE) patients with healthy controls; and 2) evaluate the relationship between the 2 major psychologic factors (anxiety and depression) and TE.Summary Statement
Background
Shoulder motion results from a complex interaction between the interconnected segments of the shoulder girdle. Coordination is necessary for normal shoulder function and is achieved by synchronous and coordinated muscle activity. During rotational movements, the humeral head translates on the glenoid fossa in the anterior-posterior plane. Tension developed by the rotator cuff muscles compresses the humeral head into the glenoid fossa. This acts to limit the degree of humeral head translation and establishes a stable GH fulcrum about which the arm can be moved. Previous studies have been limited by the use of contrived movement protocols and muscular coordination has not been previously considered with regard to shoulder rotation movements. This study reports the activation profile and coordination of 13 muscles and 4 muscle groups during a dynamic rotational movement task based on activities of daily living. Eleven healthy male volunteers were included in the study. Electromyography (EMG) was recorded from 13 muscles (10 surface and 3 fine-wire intramuscular electrodes) using a wireless EMG system. EMG was recorded during a movement task in which the shoulder was consecutively rotated internally (phase 1) and externally (phase 2) with a weight in the hand. Muscle group data was calculated by ensemble averaging the activity of the individual component muscles. Mean signal amplitude and Pearson correlation coefficient (PCC) analysed muscle activation and coordination, respectively.Introduction
Methods
The aim of this study was to evaluate prospectively the outcome following arthroscopic Bankart repair using two types of suture anchors, absorbable and non-absorbable. Patients with a diagnosis of recurrent traumatic anterior instability of the shoulder, seen between April 2000 and June 2003 in a single unit, were considered for inclusion in the study. Patients were assessed pre-operatively and post-operatively using a subjective patient related outcome measurement tool (Oxford instability score), a visual analogue scale for pain and instability (VAS Pain and VAS instability) and a quality of life questionnaire (SF-12). The incidence of recurrent instability and the level of sporting ability were recorded. Patients were randomised to undergo surgical repair with either non-absorbable or absorbable anchors. 130 patients were included in the study. 6 patients were lost to follow-up and 124 patients (95%) completed the study. Both types of anchors were highly effective. There were no differences in the rate of recurrence or any of the scores between the two. Four patients in the non-absorbable group and 3 in the absorbable group experienced further episodes of dislocation after a traumatic event. The rate of redislocation in the whole series was therefore, 5.6%. In addition, 4 patients, all of them in the absorbable group (4%) described ongoing symptoms of instability but no true dislocations. 85% of the patients have returned to their previous level of sporting activity. There are no differences in the outcome of Arthroscopic Bankart repair using either absorbable or non-absorbable anchors. Both are highly effective, showing a redislocation rate of 5.6%.
Review of the literature involving the use of viscoseal in shoulder surgery revealed no direct comparison with diamorphine, but only to bupivacaine alone. Many methods of post-arthroscopic pain relief are available. In our hospital diamorphine with bupivacaine is standard, at £2.57 per treatment. In the present study nausea was significantly lower in the Vicoseal group, but no significant intervention was required and oral anti-emetics sufficed. Pain was not significantly different, and there were no significant differences in supplementary analgesia or in early discharge. In our opinion, the significant improvement in nausea alone is not enough to justify the high price of £52.88 per Vicoseal treatment. We believe that the benefits for routine use have not been demonstrated.
