Sixty closed fractures of the tibia were treated by open reduction and internal fixation with plates and screws. Half the operations were performed with a thigh tourniquet and half without. In the tourniquet group, there were six cases with erythema and induration of the wound; in the other group there were no such complications. Despite negative bacterial cultures, superficial infection of the inflamed wounds was suspected. It is suggested that a tourniquet may predispose tissues to infection, and its use is not recommended during operations for internal fixation of the tibia

We reviewed 55 patients (78 feet) who had undergone silicone hemiarthroplasty of the first metatarsophalangeal joint for hallux valgus (40) or hallux rigidus (38). At a mean period of 4.5 years (1 to 11), 56 feet had radiological evidence suggestive of silicone granulomatous disease. The frequency and severity of the changes increased with time from the operation. Histological material from three revisions confirmed the presence of silicone granulomata. We recommend that the operation of silicone hemiarthroplasty for hallux valgus and hallux rigidus be abandoned

The history of surgery is to a large extent written around the record of its technical advances. A pneumatic tourniquet is a humble instrument, when compared with many of the more complicated mechanical devices in the modern operation theatre. Nevertheless, it has played a significant role in making possible the precise operations of present-day orthopaedics. Simple tool though the tourniquet may be, its application carries many potential dangers, and it should only he entrusted to skilled hands

The aim of this study was to analyse the functional outcome after a displaced intracapsular fracture of the femoral neck in active patients aged over 70 years without osteoarthritis or rheumatoid arthritis of the hip, randomised to receive either a hemiarthroplasty or a total hip replacement (THR). We studied 252 patients of whom 47 (19%) were men, with a mean age of 81.1 years (70.2 to 95.6). They were randomly allocated to be treated with either a cemented hemiarthroplasty (137 patients) or cemented THR (115 patients). At one- and five-year follow-up no differences were observed in the modified Harris hip score, revision rate of the prosthesis, local and general complications, or mortality. The intra-operative blood loss was lower in the hemiarthroplasty group (7% > 500 ml) than in the THR group (26% > 500 ml) and the duration of surgery was longer in the THR group (28% > 1.5 hours versus 12% > 1.5 hours). There were no dislocations of any bipolar hemiarthroplasty and eight dislocations of a THR during follow-up. Because of a higher intra-operative blood loss (p < 0.001), an increased duration of the operation (p < 0.001) and a higher number of early and late dislocations (p = 0.002), we do not recommend THR as the treatment of choice in patients aged ≥ 70 years with a fracture of the femoral neck in the absence of advanced radiological osteoarthritis or rheumatoid arthritis of the hip

Three cases of severe osteogenesis imperfecta are reported. Each was treated by closed intramedullary rodding, combined with osteoclasis to correct deformity. Operation was performed within a few months of birth. Both tibiae and both femora were stabilised in one operation, using x-ray image intensification to monitor placement of the rods. The technique used to insert the rods is described. The procedure appeared to be entirely satisfactory in reducing the incidence of fractures and it allowed the affected infants to be handled much more easily

Reimplantation is a well-established procedure in reconstructive surgery. This is especially so after amputation of the upper limb since prostheses provide limited function. In unilateral amputation of the lower leg orthotopic reimplantation is the treatment of choice. With bilateral amputation, in which orthotopic reimplantation is not possible because of the complexity of the trauma, heterotopic reimplantation is an option. We report five patients who received orthotopic and two who received heterotopic reimplantations of the lower leg. We assessed the functional outcome with reference to cutaneous sensation, mobility, pain, and the cosmetic result. The functional outcome was good, as was the patients’ satisfaction. Their mobility, stability, and psychological state were satisfactory. Patients with heterotopic reimplantations preferred the reimplanted leg to a prosthesis. Although reimplantation of the lower leg requires prolonged hospitalisation, delayed mobilisation and secondary operations, we conclude that there is an indication for this operation in order to improve the patient’s quality of life

At operation for the correction of cubitus varus by removal of a wedge based laterally, the radial nerve fortunately was first explored and found to run through a transverse bony tunnel at the posterior level of a supracondylar fracture sustained eight years previously. After elevation of the bony tunnel and nerve en bloc the osteotomy was completed; neurapraxia of the radial nerve soon recovered. With hindsight, the entrance and exit foramina of the tunnel could be clearly seen in the antero-posterior radiograph taken before the operation

1. Three patients with enchondromata of the metacarpal bones are described. 2. The nature of the enchondromata in all three patients was confirmed by histological examination. 3. Treatment was by radical excision and bridging of the gap by a cortical bone graft. 4. There has been no impairment of function in the hands. No patient complained of pain after the operation. 5. Radiographs taken one year after operation in two patients showed that the flat bone grafts had become cylindrical and that medullary canals had appeared

Aims

The aims of this study were to assess the exposure and preservation of the abductor mechanism during primary total hip arthroplasty (THA) using the posterior approach, and to evaluate gluteus maximus transfer to restore abductor function of chronically avulsed gluteus medius and minimus.

An alternative to Syme's amputation for congenital absence of the fibula is described in this paper. Nine children have had the ankle reconstructed using the Gruca technique with a very satisfactory result in eight. This procedure is not suitable for every patient and in most unilateral cases the operation can only be regarded as an interim procedure because of progressive leg-length inequality. The decision to remove the foot may be delayed and it allows childhood to be spent without resort to prostheses. However, the procedure can be considered as the definitive operation in cases of bilateral deformity

An unusually wide pneumatic tourniquet has recently become available; we provide a simple formula for its use with a low but effective inflation pressure. A prospective, randomised and controlled trial in 600 lower limb and 150 upper limb operations is reported. The wide tourniquet (12.5 cm) was as effective at low pressure as was a conventional tourniquet (9 cm) inflated to significantly higher pressures. Fewer patients suffered from painful paraesthesiae after operation using the broad, low-pressure tourniquet

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

An electromyographic investigation of patients with subluxation of the patella has been carried out on the parts of the extensor apparatus which actively contribute to the alignment of the patella, both before and after the operation to correct this disorder. The electromyographic pictures have revealed a sharp fall in the activity of the vastus medialis, with full recovery to normal values after a corrective operation. Even if the aligning function of the patella is altered by a variety of factors, the present study confirms the importance of the vastus medialis in the pathogenesis of malalignment of the extensor mechanism

Simple decompression of the extensor tendons at the wrist was carried out on fifty-four wrists in a total of forty-one patients with rheumatoid disease. This procedure was combined with excision of the ulnar head in forty-five wrists. Complete resolution of the synovitis occurred in 81.5 per cent of the wrists. In two patients the tendons ruptured soon after operation and in both cases this was due to prolapse of the ulnar stump after an associated Darrach procedure. The clinical results of decompression compare favourably with those of the widely accepted operation of dorsal tenosynovectomy

We report the results of a new surgical procedure for spastic equinovarus deformity due to cerebral palsy. This is the transfer of the anterior half of the split tibialis posterior to the dorsum of the foot through the interosseous membrane. We performed the operation on 23 feet in 18 children. All patients were assessed before operation and at follow-up at a mean of 8.4 years postoperatively. Using the criteria of Kling et al (1985), excellent results were obtained in 14 feet, good results in eight, and a poor result in only one

1. A review of nineteen cases of malignant spinal tumour treated surgically is presented. 2. Four cases are presented in detail. 3. The results in terms of survival are not assessed, because the effect of operation on survival cannot be estimated in a small series without controls. However, if the patient does survive for a considerable time, the value of operation can be assessed in terms of its contribution to the quality of survival, in relieving pain or improving or protecting neurological function. 4. The limitations of laminectomy are compared with the possible advantages of anterior approaches

1. In chronic osteomyelitis grafting a cavity with split skin is a reliable method of treatment. The skin cover so obtained is durable. 2. The method may be used with good prospects of success even when the cavity is large and there is extensive disease of bone. 3. Operation is indicated for the relief of pain, to close a sinus or sinuses, to obtain healing of an ulcer or to prevent recurrent episodes of acute infection. 4. The technique of operation employed in eleven cases is described and illustrative case reports are given

1. The cases of six Chinese children affected by so-called congenital fibrosis of the vastus intermedius muscle are described. The reasons for the choice of name are discussed. 2. Reasons for early operation are put forward: in young children simple division of the tendon of the vastus intermedius is adequate. 3. With increasing age severe changes in all the joint tissues occur, notably in the articular cartilage of the patella. These changes are likely to vitiate the result after operation. 4. The importance of getting as much flexion as possible in children of Asiatic race is stressed

The results of Charnley stabilisation of the hip in forty-three patients observed for one to four and a half years are reported. The operation readily produced a bony fusion in young patients and also in some of the older ones. Fibrous ankylosis, with or without some movement in the joint, gave an excellent result. Even when a pseudarthrosis or a stress fracture occurred, the clinical result often showed a definite improvement. Only three patients did not benefit from the operation, though none of these showed any significant increase in their disability

We compared the dynamic instability of 25 dysplastic hips in 25 patients using triaxial accelerometry before and one year after periacetabular osteotomy. We also evaluated the hips clinically using the Harris hip score and assessed acetabular orientation by radiography before surgery and after one year. The mean overall magnitude of acceleration was significantly reduced from 2.30 m/s. 2. (. sd. 0.57) before operation to 1.55 m/s. 2. (. sd. 0.31) afterwards. The mean Harris hip score improved from 78.08 (47 to 96) to 95.36 points (88 to 100). The radiographic parameters all showed significant improvements. This study suggests that periacetabular osteotomy provides pain relief, improves acetabular cover and reduces the dynamic instability in patients with dysplastic hips
