Endoprosthetic reconstruction following resection of 31 tumours of the proximal femur in 30 patients was performed using a Wagner SL femoral revision stem. The mean follow-up was 25.6 months (0.6 to 130.0). Of the 28 patients with a metastasis, 27 died within a mean follow-up period of 18.1 months (0.6 to 56.3) after the operation, and the remaining patient was excluded from the study 44.4 months post-operatively when the stem was removed. The two patients with primary bone tumours were still alive at the latest follow-up of 81.0 and 130.0 months, respectively. One stem only was removed for suspected low-grade infection 44.4 months post-operatively. The worst-case survival rate with removal of the stem for any cause and/or loss to follow-up was 80.0% (95% confidence interval 44.9 to 100) at 130.0 months. The mean Karnofsky index increased from 44.2% (20% to 70%) pre-operatively to 59.7% (0% to 100%) post-operatively, and the mean Merle d’Aubigné score improved from 4.5 (0 to 15) to 12.0 (0 to 18). The mean post-operative Musculoskeletal Tumour Society score was 62.4% (3.3% to 100%). The Wagner SL femoral revision stem offers an alternative to special tumour prostheses for the treatment of primary and secondary tumours of the proximal femur. The mid-term results are very promising, but long-term experience is necessary

Corticosteroid use has been implicated in the development of osteonecrosis of the femoral head (ONFH). The exact mechanism and predisposing factors such as age, gender, dosage, type and combination of steroid treatment remain controversial. Between March and July 2003, a total of 539 patients with severe acute respiratory syndrome (SARS) were treated with five different types of steroid. There were 129 men (24%) and 410 women (76%) with a mean age of 33.7 years (21 to 59). Routine screening was undertaken with radiographs, MRI and/or CT to determine the incidence of ONFH. Of the 129 male patients with SARS, 51 (39.5%) were diagnosed as suffering from ONFH, compared with only 79 of 410 female patients (19.3%). The incidence of ONFH in the patients aged between 20 and 49 years was much higher than that of the group aged between 50 and 59 years (25.9% (127 of 491) versus 6.3% (3 of 48); p = 0.018). The incidence of ONFH in patients receiving one type of steroid was 12.5% (21 of 168), which was much lower than patients receiving two different types (28.6%; 96 of 336) or three different types of steroid (37.1%; 13 of 35).

In a prospective, randomised trial of 81 patients with fractures of the ankle of AO types A, B and C we compared two regimes of postoperative management after internal fixation. The patients were mobilised either non-weight-bearing with crutches or weight-bearing in a below-knee walking plaster. We found a temporary benefit in subjective evaluation only (65 v 50 points, Mann-Whitney test, cft, p = 0.02) for those with a below-knee walking plaster. There were no significant differences between the groups in the loaded dorsal range of movement (25° v 23°, Mann-Whitney test, cft, p = 0.16) or in the overall clinical result. Both treatments were considered to be satisfactory and their choice depends on the ability to mobilise non-weight-bearing, wound healing, the type of work and personal preference

Seventeen patients, with an average age of nine years 11 months, underwent 18 Chiari osteotomies for the treatment of painful subluxation of the hips following Perthes' disease. The average follow-up period was four years three months. The 13 patients reviewed clinically all did well and none complained of pain or instability. The radiographs were examined in all 17 cases. The average centre-edge angle and percentage femoral head cover were definitely improved by the operation. No significant medical displacement of the femoral head was achieved. The clinical success may result from improved femoral head coverage and diminished eccentricity. Chiari's osteotomy is recommended for adolescent patients with painful subluxation of the hip as a consequence of Perthes' disease

In order to compare the outcome from surgical repair and physiotherapy, 103 patients with symptomatic small and medium-sized tears of the rotator cuff were randomly allocated to one of the two approaches. The primary outcome measure was the Constant score, and secondary outcome measures included the self-report section of the American Shoulder and Elbow Surgeons score, the Short Form 36 Health Survey and subscores for shoulder movement, pain, strength and patient satisfaction. Scores were taken at baseline and after six and 12 months by a blinded assessor. Nine patients (18%) with insufficient benefit from physiotherapy after at least 15 treatment sessions underwent secondary surgical treatment. Analysis of between-group differences showed better results for the surgery group on the Constant scale (difference 13.0 points, p − 0.002), on the American Shoulder and Elbow surgeons scale (difference 16.1 points, p < 0.0005), for pain-free abduction (difference 28.8°, p = 0.003) and for reduction in pain (difference on a visual analogue scale −1.7 cm, p < 0.0005)

We report the results of a prospective study of 23 patients in which interstitial laser photocoagulation (ILP) was used to treat an osteoid osteoma. ILP is a technique in which tumour tissue is destroyed by direct heating using low-power laser light energy delivered by thin (400 μm) optical fibres which are introduced percutaneously into the tumour under image guidance. Pain was evaluated before operation and at the latest follow-up using a visual analogue scale with 0 denoting no pain and 10 the worst pain imaginable. The mean follow-up was for 15 months. The results showed that the mean pain score decreased from 7.5 before operation to 0.95 at the latest follow-up. Fourteen patients had no pain and eight had minor discomfort, not requiring analgesia. One patient required a second procedure because placement of the fibre had not been accurate enough and one developed recurrent symptoms eight months after treatment. All patients were satisfied with the operation because of the rapid resolution of pain, the minimally invasive nature of the procedure, and the fact that there was no postoperative restriction of activity

In a retrospective study we compared the results of 31 Wilson and 31 Hohmann osteotomies of the first metatarsal in the treatment of hallux valgus. There were no differences between the two operations in terms of patient satisfaction, pain relief, appearance, footwear and walking ability. First metatarsal shortening was the same after both operations, and the degree of shortening was unrelated to either the clinical or the pedobarographic findings. Although the long-term radiographic changes after the Hohmann osteotomy were more worrying, the pedobarographic patterns tended to be worse after the Wilson osteotomy. There were no poor results and the numbers of feet with the same final grade were identical in each group. However, there was abnormal loading of the lateral metatarsal heads after both osteotomies when compared with the normal foot, and hallux-contact time during the stance phase was also significantly reduced after osteotomy

We performed a prospective, randomised trial comparing three treatments for displaced intracapsular fractures of the hip in 280 patients aged 65 to 79 years. The mean patient survival was significantly higher in the group undergoing reduction and internal fixation (79 months) compared with that with a cemented Thompson hemiarthroplasty or a cemented Monk bipolar hemiarthroplasty (61 months and 68 months, respectively). After three years, 32 of 93 patients (34.4%) who had undergone fixation had local complications, necessitating further intervention in 28 (30%). There were no significant differences in the functional outcome in survivors, who were reviewed annually to five years. Either reduction and internal fixation or cemented hemiarthroplasty may be offered as alternative treatments for a displaced intracapsular fracture in a mobile and mentally competent patient under the age of 80 years. The choice of procedure by the patient and the surgeon should be determined by the realisation that the use of internal fixation is associated with a 30% risk of failure requiring further surgery. If this is accepted, however, hemiarthroplasty is avoided, which, in our study has a significantly shorter mean survival time. The use of a bipolar prosthesis has no significant advantage

In a randomised trial involving 598 patients with 600 trochanteric fractures of the hip, the fractures were treated with either a sliding hip screw (n = 300) or a Targon PF intramedullary nail (n = 300). The mean age of the patients was 82 years (26 to 104). All surviving patients were reviewed at one year with functional outcome assessed by a research nurse blinded to the treatment used. The intramedullary nail was found to have a slightly increased mean operative time (46 minutes (. sd. 12.3) versus 49 minutes (. sd. 12.7), p < 0.001) and an increased mean radiological screening time (0.3 minutes (. sd. 0.2) versus 0.5 minutes (. sd. 0.3), p <  0.001). Operative difficulties were more common with the intramedullary nail. There was no statistically significant difference between implants for wound healing complications (p = 1), or need for post-operative blood transfusion (p = 1), and medical complications were similarly distributed in both groups. There was a tendency to fewer revisions of fixation or conversion to an arthroplasty in the nail group, although the difference was not statistically significant (nine versus three cases, p = 0.14). The extent of shortening, loss of hip flexion, mortality and degree of residual pain were similar in both groups. The recovery of mobility was superior for those treated with the intramedullary nails (p = 0.01 at one year from injury). In summary, both implants produced comparable results but there was a tendency to better return of mobility for those treated with the intramedullary nail

1. A simple test more sensitive than Ortolani's for the diagnosis of instability of the hip in the new-born is described. It takes only a few seconds to perform and can be quickly taught to doctors, nurses and midwives. 2. About one infant in sixty is born with instability of one or both hips. Over 60 per cent of these recover in the first week of life, and 88 per cent in the first two months. The remaining 12 per cent are true congenital dislocations and persist unless treated, giving an incidence of 1·55 per thousand. 3. Treatment with the type of splint described begun within the first week is simple and effective, and gives a hip clinically normal long before the child begins to walk. 4. The concept of a pre-dislocation phase should be abandoned

This is a prospective study of 105 knees in 91 patients with idiopathic osteonecrosis of the femoral condyles, with an average follow-up of five years in 101 knees. Forty-eight of the 75 patients in whom the body weight was studied were obese and four of the 33 patients in whom a densitometry study was done showed decreased bone density. Prognosis is unfavourable if the lesion is larger than five square centimetres and if its width is more than 40 per cent of that of the condyle. Of the 22 patients followed up after conservative treatment 80 per cent were satisfactory. Of the 11 knees treated by arthrotomy alone 55 per cent were satisfactory. Of the 31 knees treated by osteotomy (21 with associated arthrotomy) 87 per cent were satisfactory. Arthrotomy did not significantly improve the results of osteotomies. The ideal correction was to 10 degrees of valgus. Of the 37 knees treated with replacement 95 per cent were satisfactory, and the best results were obtained with the total-condylar prosthesis

The efficacy of modern drugs in the treatment of tuberculosis of the spine has been evaluated by a personal follow-up for three to ten years. Operation on the vertebral lesion was done only for those patients with or without neural complications who failed to respond favourably to drug therapy and rest. Thus absolute indications for operation were present in only 6 per cent of cases without neural involvement and in 60 per cent of patients with neural deficit. Of the patients who responded to drug therapy alone, only 19 per cent revealed increase of kyphosis by more than 10 degrees. The diseased area showed radiological evidence of osseous replacement in 29.6 per cent of cases, of fibro-osseous union in 50 per cent and of fibrous replacement in 202 per cent. The overall results of this regime compare favourably with those of radical operation. It is suggested that freatment should in the first place be by modern antitubercular drugs

We carried out the Bernese periacetabular osteotomy for the treatment of 13 dysplastic hips in 11 skeletally mature patients with an underlying neurological diagnosis. Seven hips had flaccid paralysis and six were spastic. The mean age at the time of surgery was 23 years and the mean length of follow-up was 6.4 years. Preoperatively, 11 hips had pain and two had progressive subluxation. Before operation the mean Tönnis angle was 33°, the mean centre-edge angle was −10°, and the mean extrusion index was 53%. Postoperatively, they were 8°, 25° and 15%, respectively. Pain was eliminated in 7 patients and reduced in four in those who had preoperative pain. One patient developed pain secondary to anterior impingement from excessive retroversion of the acetabulum. Four required a varus proximal femoral osteotomy at the time of the pelvic procedure and one a late varus proximal femoral osteotomy for progressive subluxation. Before operation no patient had arthritis. At the most recent follow-up one had early arthritis of the hip (Tönnis grade I) and one had advanced arthritis (Tönnis grade III). Our results suggest that the Bernese periacetabular osteotomy can be used successfully to treat neurogenic acetabular dysplasia in skeletally mature patients

Fifty-five cases of osteosarcoma of the extremities were treated between 1972 and 1976 by combined surgery and chemotherapy (vincristine, adriamycin and methotrexate in medium doses) for 18 months. The follow-up ranges from 30 to 80 months (mean = 48 months). Twenty-six patients remained free from any evidence of disease, two had local recurrences but no metastases and 27 had metastases (four of these also had local recurrences). In 12 patients, the metastases appeared after the end of chemotherapy. Both metastases and local recurrences were more frequent in patients who had segmental bone resection (7/8) than in those treated by more radical surgery (22/47). Comparison with an "historical" group (94 osteosarcoma patients treated by operation alone in our Institute between 1960 and 1971) showed that the percentage of patients free from evidence of disease was higher in the group who receiving chemotherapy. In addition, the appearance of metastases in this group was delayed (mean = 16 months) as compared with the historical controls (mean = 8 months). On the other hand, after the same kind of operative treatment, the rate of local recurrences and the time of their appearance was almost identical in both groups

1 . In the common type of Volkmann's ischaemic contracture affecting the forearm flexors, the infarct takes the form of an ellipsoid with its axis in the line of the anterior interosseous artery and with its central point a little above the middle of the forearm. The greatest damage is at the centre and usually falls most heavily on flexor digitorum profundus and flexor pollicis longus, which are often necrotic. Those muscles more superficially placed, and sometimes the deep extensors, are more likely to exhibit fibrosis. 2. The median nerve runs near the centre of the ellipsoid and may exhibit profound ischaemia. The ulnar nerve, lying at the edge of the ischaemic zone, tends to be less severely affected. 3. The treatment for this condition is excision of all tissues irreparably damaged by ischaemia. If this operation is performed within twelve months from the time of injury, correction of the contracture should be almost complete. The tendons of shortened but active muscles are lengthened or transplanted. 4. After such excision it is possible to carry out reconstructive procedures commonly used in the surgery of lower motor neurone disorders and of trauma. A wide variety of tendon transplantations is available. The median nerve may be repaired either by a free graft or, in cases where both nerves have been extensively damaged by ischaemia, by an ulnar to median nerve-pedicle graft

Hinged casts and roller traction were used in two developing countries to treat fractured femora, most of which were due to road traffic accidents or civil violence. This method of treatment, developed by Neufeld, is particularly useful in the Third World because it uses local materials, adapted in a hospital workshop, and circumvents the difficulties and complications of standard traction and of operative treatment. The results are reported from 11 patients treated in Uganda in 1979 and from 110 treated in the Dominican Republic in 1981 and 1982. All but one fracture united without complication or significant shortening after a brief period in hospital. The method was easily taught to hospital staff and is strongly recommended

A method of treatment of Volkmann's ischaemic contracture is described which retains wrist movement and restores reasonably good function to the hand in suitable cases

The case histories of 361 subcapital fractures of the femoral neck in 354 patients treated by primary replacement with the cemented Thompson prosthesis were reviewed, and 156 survivors were seen at follow-up. The average age was eighty-one years. Three hundred and thirty fractures occurred in women and thirty-one in men. The antero-lateral approach to the hip was used at all operations because it allows immediate and unrestricted mobilisation after operation. It is considered that this method is the best treatment in the rehabilitation of elderly patients after high femoral neck fractures, because of its low morbidity and high success rate in returning the geriatric orthopaedic patient to independence. The results after an average of just over three years were available for 161 hips in 156 patients studied at follow-up. Of these, 132 (82 per cent) were satisfactory. Most of the unsatisfactory results were in patients under seventy-five years of age. Out of the whole group of 361 hips treated the important early complications were wound infections in seventeen hips 4-7 per cent), all of which resolved, and dislocation in seven hips (2 per cent). Forty-six patients (12-9 per cent) died during the first four weeks after operation, their average age being eighty-five. One hundred and seventy-one patients (47-4 per cent) were discharged from hospital within under four weeks of the operation. Acetabular erosion and loosening are shown to be the important later complications. Three patients had late sepsis

1. The results of fifty-three operations in forty adults with a persistent congenital dislocation of the hip have been reviewed. 2. Arthrodesis as a primary operation was successful in five of six patients, giving a pain-free hip and good function. After an arthroplasty or an osteotomy that had failed to relieve symptoms it was successful in only one patient. 3. Cup arthroplasty on one hip relieved pain in five of nine patients, giving an increase in functional activity, although the range of hip movement was often disappointing. Bilateral cup arthroplasty, performed in four patients, gave partial relief in three, but did not permit an increase in activity. 4. High osteotomy of the femur was undertaken in eleven patients with a unilateral dislocation; pain was rarely relieved, and a stiff hip resulted in seven. 5. Low osteotomy in nine patients gave some relief from pain with a good range of hip movement. 6. In unilateral dislocation arthrodesis appeared to be the operation of choice, although cup arthroplasty was capable of giving a good functional result. 7. In bilateral dislocation, when only one hip was painful, the results of both these operations were on the whole good. When both hips were painful the operations that had been performed seldom gave clinical improvement. 8. High osteotomy of the femur appeared to have little place in the treatment of the painful dislocated hip. Low osteotomy, either of the Schanz or Batchelor type, appeared to be of value mainly as a salvage procedure when other measures had failed to give relief

Aims

The aim of this large registry-based study was to compare mid-term survival rates of cemented femoral stems of different designs used in hemiarthroplasty for a fracture of the femoral neck.
