Two patients with acute osteomyelitis of the foot caused by mixed aerobic organisms are described; sources of infection and predisposing factors are discussed. Serratia marcescens was isolated in each instance. Antimicrobial therapy which did cover this organism failed; a change to treatment directed against it succeeded

Aims

The aim of this study was to describe implant and patient-reported outcome in patients with a unilateral transfemoral amputation (TFA) treated with a bone-anchored, transcutaneous prosthesis.

Thirty patients with non-tuberculous pyogenic osteomyelitis of the spine are reported in all of whom the diagnosis was confirmed bacteriologically, histologically or serologically. The clinical and radiological features and investigations are analysed. Back pain, localised to the level involved, was the predominant symptom. The erythrocyte sedimentation rate was raised in all cases, and a characteristic sequence of radiological features is described

In the neonate, Group B beta-haemolytic streptococcal osteomyelitis presents with few inflammatory signs, a mild clinical course, extensive bony destruction, and usually single bone involvement. Onset is late (10 to 60 days after birth) and obstetric trauma appears to predispose to infection. Serotype studies suggest transmission from mother to child at the time of delivery

1. Attention is drawn to the danger of avascular necrosis developing in the capital femoral epiphysis as a complication of osteomyelitis in the intertrochanteric region. 2. This necrosis is commonly aseptic. It is believed to be caused by compression or thrombosis of the epiphysial vessels. 3. The situation will be aggravated if infection spreads to involve the joint. 4. We believe that prompt decompression of both the joint and the bone is indicated in order to reduce the incidence and severity of these complications

1. Three cases of osteomyelitis of a metatarsal sesamoid bone are described. 2. The diagnosis should be considered in patients with acute pain under the first metatarsophalangeal joint, particularly if the temperature is elevated. 3. Failure ofdiagnosis may lead to persistent disability until sinus formation and sequestration dictate operative intervention. 4. Early antibiotic therapy may lead to resolution of the infection

The localisation of acute haematogenous pyogenic osteomyelitis following a local injury is well known. Whilst there is often a history of trauma in patients developing bone and joint tuberculosis, its role is obscure. Two patients are reported who developed histologically proven tuberculosis in the vicinity of closed fractures during the healing process. These two patients make a total of four so far reported

We present three young men who sustained closed diaphyseal fracture of the tibia and later developed severe osteocutaneous necrosis induced by heat during intramedullary reaming. They all had a narrow medullary cavity and in all a tourniquet had been used. Each developed a pretibial cutaneous blister soon after operation. In the following month severe osteomyelitis ensued, requiring segmental resection and osteocutaneous reconstruction

In our practice sequestration of the shafts of long bones in children because of acute osteomyelitis continues to be a problem. Conventional procedures for bone grafting are likely to fail. Vascularised grafts with microvascular anastomosis are technically demanding with a high rate of failure. Transfer of the rib on its vascular pedicle to achieve anterior fusion in the thoracic spine is now well established and the length of the pedicle available is adequate to allow grafting of a diaphyseal defect in the humerus. We describe the successful use of this procedure in two patients

1. Three cases of metaphysial fractures in infants are described. Obstetrical trauma was probably responsible in two cases, and in the third case direct injury was admitted by the parents. 2. These fractures are associated with bone destruction and periosteal new bone formation in the metaphyses. They are important because they can be confused with syphilis, tuberculosis, scurvy, osteomyelitis and neoplasm. 3. The fractures respond to conservative treatment and usually heal rapidly in a matter of weeks

1. Five cases of Salmonella osteomyelitis in infants without red-cell sickling are reported. 2. All these cases occurred in children under eighteen months of age and within a period of five months of time, suggesting a seasonal incidence. 3. Only one strain of Salmonella was isolated–Salmonella typhimurium. 4. There was complete healing in four of the cases. 5. In one case there was destruction and complete absorption ofthe upper humeral epiphysis

1. The insertion of skull calipers is not generally known to be associated with any morbidity or mortality. 2. In the past six years the details of three fatal complications have been collected: there was one case each of cerebral abscess, subdural abscess and extradural abscess. 3. Brief notes of eleven other similar cases, five of cerebral abscess and six of osteomyelitis of the skull, have been supplied by colleagues. 4. The implications of these findings are discussed

Condensing osteitis of the clavicle was first described as a disease entity in 1974. There is painful localised swelling of the clavicle of undetermined origin, with increased radio-density, but an infective aetiology has not been excluded by previous authors. We report three children with the clinical and radiological findings of 'condensing osteitis'. Two of them had raised levels of antistaphylolysin titres and all responded to antibiotic therapy. We conclude that condensing osteitis is due to low-grade staphylococcal osteomyelitis; biopsy and treatment by antibiotics is recommended

Six different conditions of non-infective bone and joint pathology have been seen amongst 67 patients with diabetic neuropathy. The characteristics of each are described. Not all the conditions require treatment but they should be differentiated from osteomyelitis. Charcot osteoarthropathy is the most common condition seen but spontaneous fractures and dislocations generally present greater therapeutic problems. The aim of treatment should be to obtain a stable foot in which there is no undue pressure on the skin from a bony prominence

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 literature on acute osteomyelitis of the maxilla in infants is reviewed and the improvement in the prognosis since the introduction of chemotherapy is noted. 2. The clinical features, diagnosis, surgical anatomy, pathology, and bacteriology are discussed and the constant pathogenicity of the staphylococcus aureus stressed. It is suggested that the first deciduous molar tooth is the centre of the early bone infection, and that the infection begins in the mucosa overlying this tooth. 3. Two cases are reported. Both were caused by a penicillin-resistant staphylococcus aureus. 4. The early use of aureomycin in an attempt to abort the infection is advocated

Primary subacute haematogenous osteomyelitis (PSHO) of the small bones of the foot is a rare and infrequently considered cause of a limp in children. We describe 11 patients with PSHO, of whom nine were under three years of age, who had a limp with few symptoms. The talus was involved in 36%. Bone scans were positive in all patients and led to localisation of the lesion in two. The radiological features included soft-tissue swelling, an osteolytic lesion in the talus and the calcaneus and a sclerotic appearance of the cuboid and the navicular bones. All patients except one were cured with antibiotics

Gentamicin incorporated in beads of polymethylmethacrylate has been shown capable of being released over a period of several months in concentrations sufficiently high to control most pathogens. The therapeutic efficacy of such beads has been demonstrated in a model of osteomyelitis of the femur in the dog. Good tolerance has been shown, both in the animal model and in tissue cultures. In forty-one patients with infection of either bone or soft tissue, mainly of the lower limb, the findings were similar. The concentrations in serum and urine were low, which excludes side-effects. The insertion of gentamicin-PMMA beads may prove to be a valuable new form of local antibiotic therapy

1. A series of 102 cancellous strip grafts for delayed union of long bone fractures has been reviewed. 2. Half of the initial injuries were open. 3. Half of the fractures were butterfly or segmental lesions or were comminuted. 4. After strip grafting 84 per cent of the fractures were united within sixteen weeks, and only four took longer than twenty weeks. 5. Complete failure of union occurred in only one case, a tibial fracture complicated by low-grade pyocyaneus osteomyelitis. 6. A more aggressive attitude to the problem of delayed union is advocated
