Of 37 consecutive patients suffering from tuberculosis of the lumbosacral spine, 26 were reviewed after an average follow-up of 20 years. Those presenting at under 10 years of age usually had a discharging sinus or a pointing abscess and a visible kyphosis. In older patients, low back pain was the predominant presenting symptom. Neurological involvement was uncommon. Both operative and conservative treatment had resulted in fusion but all patients treated conservatively ended up with a kyphosis associated with trunk shortening. They had a higher incidence of back pain and more complications in pregnancy. Anterior debridement and fusion with a strut graft can reduce the incidence and size of kyphosis, but is technically demanding. Treatment remains difficult and requires individual consideration.

We report the results of a prospective longitudinal study of 147 athletes who had had a meniscectomy for an isolated meniscus injury. The patients were reviewed in detail after median periods of 4.5 years and 14.5 years and the results analysed. The frequency of complaints related to the operation increased from 53% at 4.5 years to 67% at 14.5 years, while demonstrable knee instability increased from 10% to 36%. The incidence of radiographic changes of degeneration rose from 40% to 89% and at late review 8% of patients had definite osteoarthritis by the criteria of Ahlback (1968). In consequence 46% had given up or reduced their sporting activity, and 6.5% had changed their occupation. Radiographic deterioration started after the 4.5-year review in 49% of the patients and was more frequent after lateral than medial meniscectomy.

One-hundred and seventy patients with 252 club feet treated by early posterior release were reviewed after a follow-up averaging 15 years 10 months. The feet were assessed both functionally and clinically and the results related to any bony deformity found radiographically; a satisfactory result was obtained in 81%. Lateral tibial torsion was examined and found to be less than in a normal population. The relationship between primary bone deformity and eventual functional result was examined, and a classification of talar dome deformity introduced. The range of ankle movement was a major factor in determining the functional result, and this in turn was influenced by the degree of talar dome flattening. It is suggested that the primary bone deformity present at birth dictates the eventual result of treatment.

Of 47 patients with spina bifida who had had transplantation of the iliopsoas more than 10 years previously, 32 (68%) were community walkers, 3 were household walkers and 12 were non-walkers. Comparison with other published reports showed that, at the very least, the patients reviewed had not had their walking ability jeopardized by the inevitable loss of hip flexor power. Furthermore, all but three of the community walkers were able to climb and descend stairs. There was a high proportion of non-walkers in those patients whose operation had been performed in the first year of life and such early surgery is no longer recommended. We also found that the pre-operative assessment of muscle power had, in some patients, been inaccurate. Finally, we found that, at review, the power of the transferred muscles was poor, suggesting that transplantation is beneficial because it achieves permanent and major reduction in hip flexor power; this usually prevents recurrent hip flexion deformity and dislocation.

1. One hundred cases of arthrodesis of first metatarso-phalangeal joint have been reviewed after a post-operative interval of at least ten years.

2. Seventy-seven per cent of patients were completely satisfied with the late results ; only 9 per cent were dissatisfied.

3. The two major factors leading to poor results were found to be malposition of the arthrodesis, and interphalangeal osteoarthritis.

4. The ideal position for fusion is considered to be in at least 20 degrees of valgus, preferably between 20 and 30 degrees ; between 20 and 40 degrees of dorsiflexion ; and most importantly, neutral rotation.

5. The precise operative technique is not important provided it maintains the position obtained at operation until the arthrodesis is sound.

We have reviewed 103 of 126 Chiari osteotomies carried out in our department between 1956 and 1987. The cases were graded radiologically, using the Japanese Orthopaedic Association (JOA) system, into a pre/early osteoarthritis (OA) group and an advanced OA group. In the pre/early group there were 86 hips. The mean follow-up was for 17.1 years (4 to 37). Preoperatively, 51 hips had an average JOA clinical score of 78.6 ± 8.4 points and the final mean JOA clinical score was 89.4 ± 12.5 points. Advanced degenerative change developed in 33.7% and one hip required a total replacement arthroplasty (TRA). Chiari osteotomy alone, without accompanying intertrochanteric osteotomy, was performed on 62 hips. For these the median survival time was 26.0 ± 2.5 years, using as the endpoint progression to advanced OA. Differences in survivorship curves related significantly to the severity of the preoperative OA, the shape of the femoral head and the level of osteotomy. In the advanced OA group, we followed up 17 hips for a mean of 16.2 years (1 to 27). Before operation, the mean JOA clinical score in 13 hips was 63.2 ± 7.9 points and the final score 84.0 ± 12.0 points. TRA was eventually carried out on four hips.

Our findings suggest that the Chiari osteotomy remains radiologically effective for about 25 years. The procedure is best suited to subluxated hips with round or flat femoral heads and early or no degenerative change. Intra-articular osteotomy can lead to osteonecrosis, and should be avoided. In hips with advanced OA, the Chiari procedure creates an acetabulum which facilitates later TRA, and may delay the need for this procedure in younger patients.

Between 1987 and 2006 we performed a modified Thompson’s quadricepsplasty on 40 fracture-related stiff knees and followed the patients for a mean of 7.9 years (2 to 11.1). The factors affecting the final gain of movement were investigated. A total of 15 knees required lengthening of the rectus femoris. The mean flexion gain was 70.2° (42.3° to 112.5°). According to Judet’s criteria, the results were excellent in 30 knees, good in seven, and fair in three. The range of movement which was achieved intra-operatively was related to the gain of knee flexion on univariate analysis. Five patients had complications: deep infection in one, recurrent patellar dislocation in one, and rupture of the extensor mechanism in three. This modified technique gives satisfactory results. Achieving maximum knee flexion intra-operatively seems to be the most important factor in enhancing the outcome in patients with stiffness of the knee following fracture.

We enrolled 98 patients (107 hips) with a mean age of 47 years (SD 8.6) into a prospective study of the Madreporic Lord THR; 34 hips had primary and 73 secondary osteoarthritis.

After ten years, the survival rate using revision as the endpoint for failure was 70% (±9) for the cup and 98% (±0.3) for the stem. The combined clinical and radiological survival rates were 46% (±11) and 81% (±10), respectively. Osteoporosis due to stress-shielding was observed in the proximal femur. Hips with radiologically dense bone postoperatively showed the most pronounced bone loss.

We recommend continued radiological follow-up of patients with this type of implant to allow revision to be performed before there is severe bony destruction of the pelvis.

We reviewed 18 hips in 17 patients at a mean of five years after performing Sugioka's transtrochanteric anterior rotational osteotomy for avascular necrosis. The results were satisfactory in only three hips (17%). Twelve hips had been revised by hip replacement, revision was pending in one and two others were unsatisfactory. Hip replacement was not compromised by the previous Sugioka osteotomy. Fifteen hips (83%) had shown further collapse of the femoral head, and we conclude from this and from isotope scans that the osteotomy may have impaired the residual blood supply of the femoral head. It seems that ethnic origin may be a factor in the outcome of this procedure; we have abandoned its use.

Radiographs of the scaphoid after injury are difficult to interpret, and bone scintigraphy is widely used to increase the accuracy of diagnosis, though many fractures suspected on scintigraphy cannot be confirmed radiologically. We have reviewed the clinical consequences, after one year, of managing suspected scaphoid fractures according to the bone-scan results. We studied 160 patients, 35 of whom had initially positive radiographs and were treated in a cast for 12 weeks. The other 125 had bone scintigraphy and were managed according to the result. After a minimum of one year 119 patients were reviewed. Scintigraphically suspected scaphoid fracture could not be confirmed radiologically in 25%. There were no cases of nonunion. The long period of immobilisation in patients with positive radiographs or positive bone scans did not influence the frequency or severity of late symptoms compared with those with a normal bone scan.

We reviewed 31 of 33 consecutive patients with intra-articular fractures of the knee at 6 to 22 years (average 14). Of these, 77% had excellent or good results; the others had various degrees of degenerative osteoarthritis. There was no significant difference between the results after surgical or conservative treatment. Secondary degeneration was not related to cause or type of fracture, but its incidence increased with the patient's age at the time of injury, though not with the length of follow-up. Early mobilisation appeared to be beneficial in preventing later degenerative changes.

We report 12 patients with infiltrating muscular lipomas of the lower limbs all treated by wide resection. During follow-up averaging seven years, the tumour recurred in five patients. Our results and those reported by others suggest that, in order to avoid recurrence, this tumour, although benign, should be treated by total excision of the muscle or by compartmental resection. Hormonal imbalance was suspected in 9 of the patients but an oestrogen receptor analysis of the histological samples proved negative.

We have reviewed a series of 94 Chiari pelvic osteotomies carried out from 1966 to 1982. In 83 hips the indication for surgery had been pain, and of these patients 73 (88%) had appreciable relief within one year of operation. The other 11 hips were all in children and were painless; in them the osteotomy had successfully stabilised progressive subluxation of the hip. At review after a mean follow-up of 10 years (range, 2 to 18 years) 68 previously painful hips were reassessed. Although function of the hips had deteriorated slowly with time, four of the seven cases with 18 years' follow-up had good function and only minor symptoms. A detailed analysis of the radiographic changes produced by the Chiari osteotomy was made, using computerised analysis of variance. The beneficial effects of the osteotomy resulted from complex changes, among which the provision of a stable fulcrum for the hip seemed to be the most important.

A subjective, objective and radiographic study of 21 patients with comminuted calcaneal fractures showing severe involvement of the subtalar joint is reported. The average follow-up was 14.6 years (range 8 to 29 years). Only patients with unilateral closed fractures and no associated injuries to either lower limb were admitted to the study. All were treated by early active mobilisation of the ankle, and the subtalar and the midtarsal joints. Seventy-six per cent of the patients achieved a good result with minor symptoms which did not interfere with their occupation or leisure requirements. Although two-thirds of the patients reached a point of maximal recovery at two to three years, 24% continued to improve for six years. None of the patients experienced any deterioration after this time. Neither the degree of clinical stiffness nor the degeneration of the subtalar joint, assessed radiographically, correlated with the severity of symptoms or functional disability. The role of the soft tissues in the aetiology of residual symptoms is discussed.

Between 1971 and 1976 eight patients underwent excision of the carpal lunate for pain from Kienbock's disease. The bone was replaced by a silicone rubber implant. An average of 84 months had elapsed when they were reviewed in December 1980. All eight were very satisfied with their operations. Objectively, the clinical results were good, but radiographs showed the presence of degenerative change in the region of the wrist and alteration of the position of the prosthesis on ulnar deviation of the hand. No implant has had to be removed.

1. The late consequences of stable fractures of the thoracic and lumbar spine have been assessed in a series of workmen. The incidence of symptoms has been recorded and an attempt made to assess the degree of associated incapacity.

2. It has been found that most patients continue to have some symptoms attributable to the back injury and that approximately one in five of the patients who attended for review was partially or completely incapacitated as a consequence of such symptoms.

3. The persistence of symptoms was found to be unrelated to the severity of fracture, to its level, to the presence of radiological evidence of degenerative change, or to the age of the patient.

4. Persistent symptoms were found more commonly in those patients who had received more treatment. The implications of this observation are discussed.
