We report a long term experience on massive rotator cuff tears treated by the means of a nonresorbable transosseously fixed patch combined with a subacromial decompression

From December 1996 until August 2002, a total of 41 patients were treated with a synthetic interposition graft and subacromial decompression. All patients had a preoperative ultrasound evidence of a primary massive full-thickness tear that was thought to be irreparable by simple suture. All patients were evaluated pre- and postoperatively using the Constant and Murley score, DASH questionnaire, Simple Shoulder Test, VAS scale for pain, ultrasound and plain radiographs.

The patients consisted of 23 men and 18 women aged 51–80 years (mean 67 years). We had a lost of follow up of 6 patients. One patient had a total shoulder arthroplasty at 7.7 years and one patient had a redo with a new synthetic graft at 9.6 years. They were followed up for a mean of 7.2 years. Their mean preoperative Constant and Murley score improved from 25.7 preoperatively to 69.6. Similar improvements were seen with the DASH score (56.6 to 23.3), SST (1.2 to 7.9) and VAS scale (75.4 to 14.1)

Anatomically, the repair resulted in mean acromio-humeral interval of 6.6 mm. Ultrasound showed a further degeneration of the rotator cuff with tears posteriorly from the interposition graft. In 67.7% of all patients the graft was continuous present. Histology – obtained from one patient scheduled for a reversed shoulder arthroplasty- showed partial ingrowth of peri-tendinous tissue.

Despite ongoing degeneration of the cuff in nearly half our population, restoring a massive rotator cuff defect with a synthetic interposition graft and subacromial decompression can give significant and lasting pain relief with a significant improvement of ADL, range of motion and strength.

Role of ultrasonography in shoulder pathology: Consistency with clinical and operative findings K. W. Chan, G. G. McLeod Department of Trauma and Orthopaedic Surgery, Perth Royal Infirmary, Perth PH1 1NX, United Kingdom.

Shoulder disorders are common and main causes of shoulder pain with/without functional deficit include adhesive capsulitis (frozen shoulder), impingement syndrome and rotator cuff pathology. The sensitivity and specificity of ultrasonography have been reported as 80% and 100% respectively in the literature. We carried out a retrospective case note review of patients that underwent ultrasonography of shoulder, comparing the radiological findings with clinical diagnosis and operative findings. 58 patients, 36 male and 22 female attended the orthopaedic outpatient clinic with painful shoulder and underwent ultrasonography of shoulder during the period of study. Mean age of patients is 55 (range 28 to 78 years old). 33 patients had ultrasonography of right shoulder, 20 patients had ultrasonography of left shoulder while 5 patients had ultrasonography of both shoulders. 79% (50/63) of the ultrasonography findings were consistent with clinical diagnosis. 17 patients had normal findings on ultrasonography and were discharged fully. 25 patients with clinical and radiological diagnosis of biceps tendon tear, calcifying tendinosis and partial/full thickness rotator cuff tear were treated conservatively. 19% (4/21) of patients with diagnosis of calcifying tendinosis had decompression surgery. 38% (8/21) of patients with diagnosis of partial/full thickness rotator cuff tear had decompression surgery + rotator cuff repair. The degree of rotator cuff tear in operative findings for 6 out of 8 patients (75%) that underwent decompression surgery +/− rotator cuff repair were consistent with ultrasonography findings. 4 patients had inconclusive ultrasonography findings and had magnetic resonance imaging to further confirm the pathology. We conclude that ultrasonography should be used as the first line of investigation in aiding the clinical diagnosis and management of shoulder disorders as it is non-invasive and cost effective. The sensitivity of ultrasonography in detecting shoulder pathology is 75% from this study.
