We prospectively compared hemiarthroplasty (HA) and total shoulder replacement (TSR) in cuff intact osteoarthritis. The 2 years postoperative review, which has been presented previously, showed an advantage of TSR over HA. This study reviewed the longer term outcome in the same patients at a minimum of 10 years to assess the longer term durability of the glenoid components. Patients with Osteoarthritis and an intact rotator cuff were intraoperatively randomisation to HA or TSR using the Global™ Shoulder Arthroplasty system after glenoid exposure. Post-operative mobilisation for the two groups was identical, and up until two years, patients were assessed using the UCLA and Constant Score, as well as analog pain scales and functional questionnaire. At the 10 year review patients were assessed using a similar range of subjective evaluations by telephone, or reviewed in the clinic as was possible Thirty-three shoulders in thirty-two patients were entered into the trial (14 HA and 19 TSR). At six months and one year, function scores and motion were similar, but the TSR group had less pain than the HA patients (p <
0.05) and this became more apparent at two years postoperatively (p<
0.02). Apart from those who died, no patients were lost to follow-up. At the two year mark postoperatively one patient in the HA group had undergone revision to TSR due to severe pain secondary to glenoid erosion, and three further HA were subsequently revised (2 at 3 years, and one at 4 years). Two shoulders in the TSR group have been revised (at 5 years and 7 years). At 10 years from the initial arthroplasty, 5 of the 14 HA and 6 of the 19 TSR had died. 10 of the 14 HA (71%) and 17 of the 19 TSR (89%) remained in situ at the time of death or at the 10 year review. Overall outcomes in each group were similar with respect to pain, function, daily activities. Based on this longer term review, our recommendation remains that TSR has advantages over HA with respect to pain and function at two years, and there has not been a reversal of the outcomes on prolonged follow-up. Revision from HA to TSR is made difficult due to glenoid erosion. Overall 89% of TSR remain insitu at death or 10 year, whereas 71% of HA were intact at the same times. The contention that HA will avoid later arthroplasty complications and, in particular, an unacceptable rate of late glenoid failure is not supported by this longer term review.
We prospectively reviewed 14 patients with deficiency of the proximal pole of the scaphoid who were treated by rib osteochondral replacement arthroplasty. Improvement in wrist function occurred in all except one patient with enhanced grip strength, less pain and maintenance of wrist movement. In 13 patients wrist function was rated as good or excellent according to the modified wrist function score of Green and O’Brien. The mean pre-operative score of 54 (35 to 80) rose to 79 (50 to 90) at review at a mean of 64 months (27 to 103). Carpal alignment did not deteriorate in any patient and there were no cases of nonunion or significant complications. This procedure can restore the mechanical integrity of the proximal pole of the scaphoid satisfactorily and maintain wrist movement while avoiding the potential complications of alternative replacement arthroplasty techniques and problems associated with vascularised grafts and salvage techniques.
Eight fractures were fixed with a single AO screw; 5 with Herbert screws; 4 with a steel wire loop and 8 with absorbable stitch.
In 2 out of the 5 patients where Herbert screws had been used there was significant migration of the screws. Additional articular damage was observed in 3 patients who were pedestrians hit by a car. All 3 ended up with restricted knee movements and poor results. Three individuals who had their knee immobilised in 250–500 of flexion developed flexion deformities, which took 12–18 months to recover.
Sickle-cell disease (SCD) is probably the commonest cause of avascular necrosis worldwide, and its prevalence appears to be rising in developed countries. Avascular necrosis of the humeral head is a common complication but has not been previously studied in detail. We have reviewed 138 patients with SCD for clinical, radiological and functional abnormalities of the shoulder, using a radiological classification designed for avascular necrosis of the shoulder. Radiographic lesions, frequently bilateral, were found in 28% and only 53% of patients had normal shoulder function. The management of this relatively common complication is difficult. Joint replacement is likely to fail and early diagnosis is important.
