In patients over 60, both Paget's disease and metastatic carcinoma are not uncommon, but it is rare for both to occur in the same patient and in the same bone. One such patient is reported; she had primary carcinoma of the vulva which metastasised to a femur already affected by Paget's disease.

Seven cases of massive osteolysis are presented. The aetiology of this disease is as yet unknown; neither age nor sex seems to be a factor in its incidence, nor are standard bone grafts or radiotherapy successful methods of treatment. However, in this series, operation produced a satisfactory outcome for five patients at a mean follow-up of 17 years; in three of these patients a custom-built prosthesis was inserted, and in one a conventional bone graft was combined with intramedullary nailing.

Allografts of intact cartilage, isolated chondrocytes and cultured chondrocytes taken from the epiphysial growth-plate and from the articular surface of immature rabbits were inserted into full thickness defects in the tibial articular surface of 160 mature rabbits. In the contralateral knees, which were used as controls, similar defects were made but no grafts were inserted. Grafts were followed up for periods of up to one year after transplantation. Both intact articular and intact growth-plate grafts produced significantly better repair than that seen in control ungrafted defects in normal joints (P less than 0.01 and P less than 0.05 respectively) and in arthritic joints (P less than 0.01). Cultured chondrocytes cut to a precise fit also produced significantly better repair than ungrafted defects in arthritic joints (P less than 0.05).

One hundred and thirty-nine discs from cadaveric lumbar spines were injected with a mixture of radio-opaque fluid and dye. Discograms were taken and the discs were then sectioned in the sagittal plane. Examination of the sections revealed that injected fluid did not at first mix with the disc matrix but pushed it aside to form pools of injected fluid. The location of these pools, and hence the appearance of a discogram, depended on the stage of degeneration of the disc. It is concluded that useful clinical information can be obtained from discograms.

Pain in front of the knee is common in athletes and is often called patellofemoral arthralgia, but it is difficult to prove that the pain arises in that joint. Thermograms of 30 athletes clinically considered to have patellofemoral arthralgia were compared with those of a similar number of unaffected athletes matched for age and sex. A comparison was also made with thermograms of two older groups of 30 patients with knee involvement from either rheumatoid arthritis or osteoarthritis. Twenty-eight of the athletes with patellofemoral arthralgia had a diagnostic pattern on thermography. The anterior knee view showed a rise in temperature on the medial side of the patella and the medialis knee view showed that this temperature rise radiated from the patellar insertion of the vastus medialis into the muscle itself. The possible aetiological role of quadriceps muscle imbalance in athletes with patellofemoral arthralgia is discussed in relation to these findings.

The results are reported of 44 consecutive Chiari innominate osteotomies performed on 39 adult patients aged between 18 and 55 years for symptoms arising from disproportion between the acetabulum and the femoral head. Predisposing causes included congenital dysplasia of the acetabulum, congenital subluxation of the hip, and Perthes' disease. Follow-up averaged 5 years 2 months. Four pre-operative categories of dysplasia and degeneration were recognised. The analysis of the results from each category made possible the recognition of clinical and radiological features likely to provide a satisfactory result. Of 32 cases now considered to have been selected appropriately, 29 (90%) achieved a significant and apparently lasting improvement. In the other 12 cases there were 9 failures--an unacceptable proportion. The features predisposing to these poor results are discussed. The operation is not difficult. It is safe, and is less demanding than the complex alternative "double", "triple" and "dial" osteotomies. In successful cases there is reduction in symptoms and in limp, and improvement of radiological appearances beginning six months after surgery and progressing to a maximum recovery two to three years later.

Tectoplasty is a new acetabuloplasty which aims to provide an extra-articular weight-bearing surface in cases of dysplastic acetabulum, hip subluxation or dislocation with a false acetabulum. The lateral wall of the iliac bone at the lateral edge of the affected acetabulum is raised as a proximally-based flap and massive bone grafts are inserted to provide a congruous, non-absorbable roof for the capsule and femoral head. An advantage is that the weight-bearing surface can be formed away from the original acetabulum, wherever the dislocated or subluxated femoral head may lie. Of 34 hips with congenital dislocation or severe subluxation treated by this method, 27 were evaluated after an average follow-up of 12 years. At review the patients averaged 35 years of age and satisfactory results with good relief of pain had been obtained in 78%. The results were unsatisfactory when degenerative changes had already developed before operation. Tectoplasty is indicated for pain due to congenital subluxation or dislocation of the hip under the age of thirty, in the absence of advanced osteoarthritis.

Hinge abduction is an abnormal movement of the hip which occurs when a femoral head, deformed as a result of avascular necrosis or Perthes' disease, fails to slide within the acetabulum. Patients with this condition present with pain and shortening and in some cases arthrodesis has been recommended. We report 27 cases in which the diagnosis had been established by arthrography. The satisfactory results of abduction-extension osteotomy of the femur in 26 hips with this condition are reported.

Four military recruits with complete distraction-type stress fractures of the femoral neck were treated conservatively. The radiographic diagnosis was made within two weeks of the onset of symptoms and the activities of the patients were matched to the clinical and radiographic progress of fracture healing. None of the fractures displaced and union occurred uneventfully. Our experience suggests that prophylactic internal fixation of these fractures is not necessary.

Arthroplasty of the hip using an interposed multi-layered cap of amniotic membrane is reported in 28 patients with tuberculous arthritis. The disease had been present from one to seven years, and five patients had multiple discharging sinuses. Follow-up was from 30 to 46 months. Amniotic tissue caused no inflammatory reaction, or obvious rejection, and 25 patients were free of symptoms, with a good range of movement and a stable joint. The three failures were caused by dislocation, fracture of the femoral neck and extra-articular bone formation respectively. Amniotic arthroplasty seems to be capable of providing a painless, mobile and stable joint in patients with tuberculosis of the hip.

Operation on the hips of patients with myelomeningocele is often followed by stiffness or ankylosis. Excision of the upper end of the femur for this condition frequently fails because of extensive new bone formation. Twelve excisions in eight patients are reported. Six of these patients had recently had spinal fusion operations; the consequent loss of ability to compensate for hip stiffness by spinal flexion had made sitting difficult or impossible. Excision or even re-excision of the upper femur failed in most cases. Careful assessment of hip mobility before spinal operations in these patients is essential and osteotomy rather than excision of the upper femur is advised.

We report a prospective study of 198 cases of subcapital fracture of the femur treated by closed reduction and fixation with a sliding compression screw-plate. This was done without regard to the patient's age or the Garden stage of the fracture. Early weight-bearing was encouraged. Of the displaced fractures 23% failed in the first year because of non-union or infection. Of the fractures which united 27% had developed avascular necrosis after three years. Despite this we believe that the sliding compression screw-plate, of proven value in the treatment of intertrochanteric fractures, is also useful for the fixation of subcapital fractures.

Seventeen patients with pathological fractures of the thoracolumbar spine which had not responded to conservative treatment are reported. All had compression of the spinal cord and/or severe pain. All (except one treated by lateral rhachotomy) were treated by anterior decompression followed by stabilisation; when the lesion was below T2 the spine was stabilised anteriorly, and when it was higher posterior instrumentation was used. Sixteen of the 17 patients benefited from the procedure.

Preliminary costectomy before Harrington instrumentation and fusion for idiopathic scoliosis allows direct excision of the rib prominence and better correction at the second-stage operation. The excised rib fragments are used as grafts, thus avoiding the need for a separate pelvic incision. The management regime and the technique of costectomy are described. The results in 42 children, most suffering from adolescent idiopathic scoliosis and all treated by this method, have been reviewed. Respiratory function in a group of these children has been compared with that of a group treated by Harrington instrumentation alone. Costectomy produced a significantly greater reduction in total lung capacity and peak expiratory flow rate but, providing the preliminary lung function tests were reasonably normal, the cosmetic and psychological effects of costectomy were very rewarding.

Four children are described, each with spontaneous osteonecrosis affecting nearly one-third of the lateral femoral condyle. All the children had a motor and a sensory deficit in the affected limb: two had been previously treated for neuroblastoma of the spine, one for an infected lumbar dermoid cyst and one had spina bifida. We consider that these disorders, singly or in combination, may lead to repeated excessive loading of the lateral femoral condyle, which cannot be appreciated in a knee that is not protected by normal sensation.

Of a consecutive series of 144 Attenborough knee replacements, 107 were re-examined between two and six years after operation and revealed a high incidence of complications. Wound problems were common and led to deep infection in four knees. When a patellar implant was used fracture of the patella followed in 17.5% of knees, but when the patella was not resurfaced 16% of knees developed patellofemoral pain of sufficient severity to require a further operation. In 10% of knees, definite loosening of one or both of the major components occurred.

A longitudinal incision resembling a bucket-handle tear was made in the menisci of 8 rabbits, 6 dogs, 11 pigs and 12 sheep. In some of the animals of each species the cut was repaired by suturing, and in others it was not. Gross inspection, as well as examination by light and electron microscopy, showed that no healing had occurred after six months in the sutured or the unsutured wounds and that the meniscus was incapable of significant intrinsic repair. In a second experiment longitudinal, transverse and T-shaped cuts were made in the menisci of 12 sheep, and a flap of synovium was sutured into the wound. Three months later there was clear evidence of healing by the formation of cartilaginous tissue. Examination by light and electron microscopy showed that the newly formed repair tissue, possibly derived by metaplasia from the synovium, had a morphology intermediate between hyaline cartilage and fibrocartilage. Synovial implantation may therefore be considered as an alternative to meniscectomy in the management of the torn meniscus.

We have reviewed 105 Liverpool Mark II knee replacements in 71 patients to assess survival and long-term results. Assessment was both clinical and radiological, using a modification of the British Orthopaedic Association knee function assessment chart, and analysis was by the survivorship method as advocated by Tew and Waugh. The follow-up period was between 13 and 113 months with 42 prostheses being in situ for over six years. Eight knees (7.6%) have been revised or arthrodesed because of infection or loosening, giving a cumulative success rate of 89% after seven years based on prosthesis survival alone. Of the remaining knees, 71.1% were either free of pain or caused only minimal pain. The cumulative success rate as judged by the stricter criteria of the prosthesis being in situ and causing little or no pain suggested a 50% survival between 73 and 96 months. Most patients (77.3%) were enthusiastic or satisfied with their results. Complications included deep wound infection (8.6%), and loosening which needed further surgery (11.4%).

Nuclear magnetic resonance imaging (MRI) was used to study the normal knee. As well as revealing bone quality, MRI provided useful information on intra-articular and extra-articular soft tissues. Midsagittal views gave clear images of the cruciate ligaments, and of the patellar and quadriceps tendons. Parasagittal views were the best for delineating the menisci which, like ligaments and tendons, are of low intensity; the semimembranosus tendon and its insertion to the proximal tibia were also seen clearly in these views. The cruciate ligaments and menisci, though visible in the coronal view also, were better seen in the sagittal view. Axial views provided information on the structure of the patella, its cartilage, the patellofemoral joint and posterior soft-tissue structures.

Thirteen patients with ruptures of the calcaneal tendon diagnosed more than four weeks after injury were reviewed. Eleven patients had operative reconstruction with tendon shortening and the postoperative follow-up ranged from one to seven years. Isometric and isokinetic measurements, as well as the strength of the triceps surae, all compared favourably with the normal contralateral leg. Only one tendon re-ruptured. Eight of the eleven patients were satisfied with the results and the two patients who had refused reconstruction had worse functional results. Late reconstruction of a ruptured calcaneal tendon is thus a worthwhile procedure.

A new technique is described for extra-articular subtalar arthrodesis; it combines the main elements of the Batchelor and the Grice procedures. Results were reviewed after a minimum of three years. Of the 25 feet treated 24 had solid fusion and had maintained the operative correction of the valgus deformity; the one non-union was due to deep infection.

Eleven patients were reviewed an average of 23 years after they had been treated by excision of a symptomatic calcaneonavicular bar in 16 of their feet. Of these feet 69% (11 feet) had a good or excellent result. Of the five failures, three feet had good results after subsequent triple arthrodesis, but two treated by repeated excision of the bar were still unsatisfactory. Beaking of the talus seen before operation correlated with poor results.

A prospective trial is reported which compares distal osteotomy of the first metatarsal with Keller's arthroplasty in the treatment of adult hallux valgus. A total of 33 patients attended for review at least three years after operation. Symptomatic improvement, as assessed by patient satisfaction, pain relief, cosmetic improvement and restoration of function, was similar in the two groups. Objective measurement showed that the range of movement of the metatarsophalangeal joint was better maintained after osteotomy, as was the relationship of the sesamoid bones to the head of the first metatarsal. Correction of the valgus deformity also was significantly better in the patients who underwent osteotomy and in these patients the first intermetatarsal angle was reduced to within normal limits. There was no evidence that initial degenerative changes or subluxation at the metatarsophalangeal joint compromised a successful result from osteotomy.

Therapeutic injection of facet joints is now widely practised, but British experience has been infrequently reported. We studied the results of injecting facet joints with a corticosteroid preparation in 50 patients suffering from the "facet syndrome". Our series included a number of extra-articular injections and these "failed injections" provide a useful control group. Results indicate that only intra-articular injections are effective; certainty of joint penetration can be ensured only by the routine use of joint arthrography.

Persistent back pain in the presence of an intact posterior fusion is commonly seen and is often regarded as being psychogenic in origin. This paper discusses five patients, all of whom were chronically disabled by such pain; all five had a confirmed posterior and/or lateral fusion. In each case lateral discography identified the disc within the fused segment as the source of symptoms and pain relief was obtained with an anterior interbody fusion. This source of pain should be considered as a possibility in similar cases of failed back surgery.

A patient with polyostotic fibrous dysplasia had several fractures of the right lower limb. An above-knee amputation was eventually performed, followed by arthrodesis of the hip. Five years later the stump became painful and swelled with dramatic rapidity. Biopsy showed that this was not due to malignant change, but that an aneurysmal bone cyst had developed in association with the fibrous dysplasia.

Double-contrast shoulder arthrograms were performed in 20 patients at an average of 30 months after operative repair of a torn rotator cuff. In 18 out of 20 shoulders the contrast medium leaked into the subacromial bursa indicating a defect in the rotator cuff. Despite this, 17 patients had complete relief of pain and 15 had a full range of shoulder elevation. The results suggest that a completely watertight closure is not essential for a good functional result, and that arthrography may not be helpful in the investigation of failure of repair.

A study of the contamination of suckers used during total hip replacement has been undertaken. Thirty suckers used throughout the operation had their tips cultured: from 11 of these bacteria were grown. The organisms found were those which have previously been implicated in deep infection of total hip replacements. In subsequent operations a further 31 suckers were used for cleaning only the femoral shaft; of these only one was contaminated. This suggests that sucker contamination is related to how long the sucker is in use; consequently it is recommended that a new sucker be used for the preparation of the femoral shaft.
