Introduction The value of collecting continuous prospective patient data, including operation records and outcome scores, is well known. In 1994, a systematic prospective patient data collection was initiated on all patients attending the Reading Shoulder Unit (RSU). Initially this was done with hand written records. In 1995 a Windows Access ® database was formulated on a portable laptop. This was used continuously through until September 2005 when an Internet web-based database was introduced. We present this collective data and trends in practice from a busy shoulder unit over this decade. Results Between 1995 and 2005, 10005 entries were made to the Reading Shoulder Unit database. 3233 patient visits to outpatient clinics were recorded. 6772 operations were recorded – this includes: arthroscopic decompressions (ASD) + AC joint excisions − 3514, MUA for frozen shoulder 842, shoulder arthroplasty 432, open stabilisation 356, arthroscopic stabilisation 192, arthroscopic rotator cuff repair (RCR) 402, open cuff repair 290, arthroscopic capsular release 78 and 248 trauma cases. Changes in the unit practice include the move from open to arthroscopic reconstructive surgery (RC and stabilisation), RCR rather than ASD alone in elderly patients with impingement and cuff weakness, and repairing partial rotator cuff tears when previously we did not. Conclusions With over 10000 continuous and prospective entries – the RSU database is invaluable for continuous audit of practice and assessment of outcomes of the different procedures. Several practices have changed through the decade; most notably from predominately open reconstructive surgery through to arthroscopic reconstructive surgery. We would recommend to every surgeon and unit to collect his own data prospectively to enable him to analyse and assess his results.

We describe the results of Copeland surface replacement shoulder arthroplasty using the mark III prosthesis in patients over 80 years of age. End-stage arthritis of the shoulder is a source of significant pain and debilitating functional loss in the elderly. An arthroplasty offers good relief of pain and may allow the patient to maintain independence. The risk-benefit ratio of shoulder replacement may be felt to be too high in an elderly age group, but there is no published evidence to support this theory. We have assessed whether the procedure was as reliable and safe as previously seen in a younger cohort of patients. Between 1993 and 2003, 213 Copeland surface replacement arthroplasty procedures were performed in our unit, of which 29 (13.6%) were undertaken in patients over the age of 80. This group of patients was followed up for a mean of 4.5 years (2.1 to 9.3). Their mean age was 84.3 years (81 to 93), the mean operating time was 40 minutes (30 to 45) and the mean in-patient stay was five days (2 to 21). There were no peri-operative deaths or significant complications. The mean Constant score adjusted for age and gender, improved from 15.1% to 77%. Copeland surface replacement shoulder arthroplasty may be performed with minimal morbidity and rapid rehabilitation in the elderly.

To report the results of the vertical apical suture Bankart lesion repair.

Fifty-nine patients (52 men and 7 women) with a mean age of twenty-seven years (range, 16 to 53 years) were studied. The mean duration of instability was 4. 1 years and mean follow-up was 42 months (range 24 to 58 months).

A laterally based T-shape capsular incision was performed with the horizontal component directed towards the glenoid neck and into the Bankart lesion. A vertical apical suture through the superior and inferior flaps of the Bankart lesion, tightens the anterior structures to allow them to snug onto the convex decorticated surface of the anterior glenoid. The inferior flap of the capsule was then shifted superiorly and the superior flap shifted inferiorly to augment the anterior capsule, with the shoulder in 20 degrees of abduction and 30 degrees of external rotation.

At final review, according to the system of Rowe et al., 94. 9% (56 patients) had a rating of good or excellent. Three patients had a recurrent dislocation due to further trauma.

The mean loss of forward elevation was 1 degree, external rotation with the arm at the side was 2. 4 degrees and external rotation in 90 degrees abduction was 2. 2 degrees. Of forty-four patients participating in sport, thirty-five (79. 5%) returned to the same sport at the same level of activity, seven returned to the same sport at a reduced level of activity and two patients did not return to sport.

The vertical apical suture repair offers a 94. 9% stability rate, a maintained range of motion and a 79. 5% return to pre-injury level of sporting activity. It is technically less demanding than the Bankart procedure. All sutures used are absorbable. Complications related to non-absorbable implants and absorbable anchors and tacks are avoided.

We report the results of arthroscopic subacromial decompression and debridement of the rotator cuff for chronic small- and medium-sized tears in 114 patients (118 shoulders) between two and five years after surgery.

The mean Constant score was improved to 69.8, and 88 shoulders (74.6%) had a satisfactory outcome. Of patients under the age of 60 years the outcome was satisfactory in 59.3%, and in those over 60 years, in 87.5% (p < 0.001). An unsatisfactory outcome was related to manual work (p < 0.001) and a duration of symptoms of more than 12 months (p < 0.05). The outcome was not related to the size of the tear, the muscles involved or biceps pathology. Further surgery was required in 25 patients after a mean of 13.7 months (3 to 35); ten tears had progressed in size, but none became irreparable. There was no relationship between the increase in the size of the tear and its initial size, the muscles involved or the presence of biceps pathology. No tear became smaller with time.

Cementless surface replacement arthroplasty of the shoulder is designed to replace the damaged joint surfaces and restore normal anatomy with minimal resection of bone. We have used the Copeland shoulder arthroplasty for 14 years. Between 1986 and 2000, 285 surface replacement arthroplasties were implanted in our unit. The prosthesis has evolved during this time, but the principle of minimal bone resection has remained the same. Between 1990 and 1994, 103 Mark-2 prostheses were inserted into 94 patients (9 bilateral). The operations were carried out for the treatment of osteoarthritis, rheumatoid arthritis, avascular necrosis, instability arthropathy, post-traumatic arthropathy and cuff arthropathy. The mean follow-up was for 6.8 years (5 to 10).

The best results were achieved in primary osteoarthritis, with Constant scores of 93.7% for total shoulder replacement and 73.5% for hemiarthroplasty. The poorest results were seen in patients with cuff arthropathy and post-traumatic arthropathy with adjusted Constant scores of 61.3% and 62.7%, respectively. Most patients (93.9%) considered their shoulder to be much better or better than before the operation. Of the 88 humeral implants available for radiological review, 61 (69.3%) showed no evidence of radiolucency, nor did 21 (35.6%) of the 59 glenoid prostheses. Three were definitely loose, and eight shoulders required revision (7.7%), two (1.9%) for primary loosening. The results of this series are comparable with those for stemmed prostheses with a similar follow-up and case mix. The cementless surface replacement arthroplasty diminishes the risk of complications involving the humeral shaft and periprosthetic fractures. Revision or arthrodesis can be undertaken easily since the bone stock has been maintained with no loss of length.
