We evaluated the long-term benefits of steroid injection in 20 consecutive patients (25 shoulders) with primary acromioclavicular arthritis using the Constant score. All patients were followed up for a minimum of 5 years. The average age of the patients was 55 years. The mean pre-injection Constant score was 61 points. At six months this improved to 81 points, (mean difference – 19.36) which was highly statistically significant (p<
0.01). There was further improvement at 12 months, on the 6-month score, mean 86 points that also showed a significant improvement on the 6-month score (p = 0.001). At 5 years the mean score was 81 points and this was a significant detoriation compared with the 12-month score (p=0.01) but still a significant improvement when compared to the preinjection scores (p<
0.0005). In addition, the younger the patients, the greater the improvement in the objective score which measures range of movement and power (r= − 0.47; p= 0.01). Female patients also had a greater improvement (r=0.405; p=0.05). We conclude that local steroid injection is an effective method of treatment for primary isolated acromioclavicular arthritis and improvement continues for at least 12 months and the benefit is felt up to 5 years though the pain relief tends to tail off long-term.
Periarticular fractures of the proximal tibia are some of the most difficult fractures to manage as open reduction and internal fixation of the fractures is plagued with complications such as non-union, delayed union, infection and post-traumatic osteoarthritis. We evaluated the results of 16 consecutive periarticular tibial fractures stabilised with the AO hybrid fixator using the Oxford Knee Score, American Orthopaedic Foot and Ankle Score (AOFAS) and X-rays of the tibia. Two patients were lost to follow up and 1 patient refused to take part in the study whose latest radiographs showed grade 4 degenerative changes. The mean follow up was 34 months (range 12 to 57 months) and the mean age was 50 years. All fractures were closed and were graded as either Schatzker 5 or 6. The fixator was applied for an average of 12 weeks. The mean Oxford Knee score was 27.2/60 (mild to moderate knee arthritis) and the mean AOFAS was 71.9/100. There was no significant malunion however 37.5% had developed radiological evidence of grade 3 or 4 post-traumatic osteoarthritis with one requiring a total knee replacement. Forty four percent of patients developed a complication with pin site infection being the commonest complication and 25% required further surgery. There were 2 nonunions with one requiring a fibular osteotomy, which subsequently united. Eighty eight percent of patients were satisfied with the procedure while 80% would recommend the procedure if required in future. From our study we feel that hybrid fixation of proximal periarticular tibial fractures is satisfactory however preoperative counselling regarding complications and the possible need for further surgery must be emphasised to the patient prior to embarking on this type of fixation.
The use of targeted ultrasound screening for ‘at risk’ hips in order to reduce the rate of surgery in developmental dysplasia of the hip (DDH) are unproven. A prospective trial was undertaken in an attempt to clarify this matter. Over an 8-year period, there were 28,676 live births. Unstable and ‘at risk’ hips were routinely targeted for ultrasound examination. One thousand eight hundred and six infants were ultrasounded, 6.3% of the birth population. Twenty-five children (18 dislocations and 7 dysplasias) required surgical intervention (0.87 per 1000 births for DDH / 0.63 per 1000 births for dislocation). Targeted ultrasound screening does not reduce the overall rate of surgery compared with the best conventional clinical screening programmes. The development of a national targeted ultrasound screening programme for ‘at risk’ hips cannot be justified on a cost or result basis.
Knee arthroscopy is probably the most common procedure performed in orthopaedic practice. A number of patients who undergo this procedure do not have any abnormality detected. Is negative arthroscopy really such an unnecessary procedure? We evaluated the outcome of patients in whom knee arthroscopy proved to be normal. Hospital records of patients who had had knee arthroscopy were retrospectively studied and all patients with a normal knee arthroscopy were selected. Fifty-three patients (55 knees) with a normal arthroscopy were included into the study. Patients were then interviewed either by telephone or questionnaire to ascertain current symptoms, job changes and patient perception of the procedure. The mean follow up was 43 months. Fifty percent of the patients had had a history of injury, and the preoperative diagnosis was thought to be a meniscal lesion or ACL rupture in 38% of patients. Sixty eight percent of the patients felt they were better and there were no complications. The incidence of all symptoms was significantly reduced after arthroscopy. A significant number of patients felt that they were better after the knee arthroscopy. The reason for this is no entirely clear. It may well be due to a placebo effect, the fact that patients now know that there is no abnormality and learn to live with the symptoms or there may be an additional benefit of the procedure itself.

A prospective trial was undertaken in an attempt to clarify this matter. Over an 8-year period, there were 28, 676 live births. Unstable and ‘at risk’ hips were routinely targeted for ultrasound examination. One thousand eight hundred and six infants were ultrasounded, 6. 3% of the birth population. Twenty-six children (19 dislocations and 7 dysplasia) required surgical intervention (0. 91 per 1000 births for DDH/0. 66 per 1000 births for dislocation) Targeted ultrasound screening does not reduce the overall rate of surgery compared with the best conventional clinical screening programmes.

Myerson and Shereff described an anatomical basis for the correction of hammertoe deformity. Based on this model we added a metatarsophalangeal soft tissue release to a proximal interphalangeal arthroplasty as our routine method of correction of hammertoes with fixed PIP joint flexion and flexible MTP joint hyperextension. Patients operated between March 1995 and January 2000 were retrospectively reviewed using the American Orthopaedic Foot and Ankle Society Scores (AOFAS) by independent assessors. There were 84 patients with 99 feet and 179 hammertoes with a median follow-up of 28 months. The median AOFAS score was 83. Eighty-three percent of patients were satisfied while 19% were dissatisfied with the procedure. Pain at the metatarsophalangeal joint was the commonest cause of dissatisfaction with 14% having moderate or severe pain. Nine percent had callus formation and 4% of toes were over-corrected. There was no statistical difference in results related to the age and sex of the patient, number of toes operated on, associated hallux valgus surgery and follow-up of less than or greater than two years. This study is based on an anatomical model and shows results comparable with other series with no recurrence of hammertoe deformity.
The effectiveness of steroid injection in the treatment of primary osteoarthritis of the acromioclavicular joint (ACJ) has been questioned. We prospectively evaluated the outcome of 20 consecutive patients (25 shoulders) with clinical and radiological evidence of primary ACJ arthritis after steroid injections. All patients were evaluated using the Constant score after a minimum of 12 months follow up. Only patients with a negative provocative test after injection of 2ml of depomedrone and lignocaine were included in the study. Eleven females (14 shoulders) and 9 males (11 shoulders) were included. The average age was 53.9 years. The mean preinjection score was 61.6 points (SD 13.12) and at 6 months this improved to 81 points, mean difference of 19.36 (CI = 14.19 – 24.53), p<
0.01, which was highly statistically significant. There was further improvement at 12 months, on the 6 month score, mean 88.4 points, mean difference of 7.4 (CI = 3.55 – 11.25), p = 0.001 which was also statistically significant. In addition, the younger the patient, the greater the improvement in the objective score which measures the range of movement and power (r = −0.47; p = 0.01). We conclude that local steroid injection is an effective method of treatment for primary isolated acromioclavicular arthritis and improvement continues for at least 12 months, but may require more than one injection.
We present the mid term results of 267, 3M Capital hip replacement performed in a single institution from 1991 to 1994. Patients were recalled back to clinic in April 1998 after the reported high failure rate of 3M hips. Fifty- nine hips were excluded from this study for various reasons. Average follow-up was 68.8 months. Nine (4.2%) have been revised for aseptic loosening at the time of review and further 10(4.8%) of the stems are radiologically loose. There was no statistical significant difference between hips that failed, regarding grade of the operating surgeon, surgical approach: trochanteric osteotomy or Hardinge, or type of prosthesis used: monoblock (stainless steel) or modular (titanium). Acetabular wear rate, width of medial cement mantle or cancellous bone at level of neck at Gruen zone7, or stems with canal fill index less than 50%, 7 cm below the level of the collar also showed no statistical difference. Male patients had higher incidence of loosening (p=0.001) which was statistically significant. Both varus and valgus alignment of the stem had higher failure rate which was significant. We could no find any obvious reason for failure in 10 of the 18 patients. The stem was either in varus or there was an inadequate cement mantle in 8 of the failed hips on the initial postoperative radiograph. A feature of this study was high incidence of endosteolysis and debonding of prosthesis from cement in the failed cases. The present series showed considerably lower revision and loosening rate of 3M stems compared to the published series, the reason for which is not clear. Only Palacos cement was used in this series, which may partly account for the lower failure rate. Surface finish of the stem leading to debonding of the prosthesis from cement along with different modulus of elasticity probably accounts for the higher rate. Technical failure is partly to blame for the higher failure rate.
Between March 1995 and January 2000 we reviewed retrospectively 84 patients with hammer-toe deformity (99 feet; 179 toes) who had undergone metatarsophalangeal soft-tissue release and proximal interphalangeal arthroplasty. The median follow-up was 28 months. Patients were assessed by the American Orthopaedic Foot and Ankle Society Scores (AOFAS) and reviewed by independent assessors. The median AOFAS score was 83, with 87% of patients having a score of more than 60 points; 83% were satisfied and 17% were dissatisfied with the procedure. Pain at the metatarsophalangeal joint was the commonest cause of dissatisfaction, with 14% having moderate or severe pain. Only 2.5% had instability and 9% had formation of callus. There was no statistical difference for the age and gender of the patients, the number of toes operated on, associated surgery for hallux valgus or length of follow-up. Our study was based on an anatomical model and shows good results with no recurrence of deformity.
