Aims

Aneurysmal bone cysts (ABCs) are locally aggressive lesions typically found in the long bones of children and adolescents. A variety of management strategies have been reported to be effective in the treatment of these lesions. The purpose of this review was to assess the effectiveness of current strategies for the management of primary ABCs of the long bones.

Aims

There is an increased risk of dislocation of the hip after the resection of a periacetabular tumour and endoprosthetic reconstruction of the defect in the hemipelvis. The aim of this study was to determine the rate and timing of dislocation and to identify its risk factors.

Aims

We present the development of a day-case total hip arthroplasty (THA) pathway in a UK National Health Service institution in conjunction with an extensive evidence-based summary of the interventions used to achieve successful day-case THA to which the protocol is founded upon.

Aims

Use of molecular sequencing methods in periprosthetic joint infection (PJI) diagnosis and organism identification have gained popularity. Next-generation sequencing (NGS) is a potentially powerful tool that is now commercially available. The purpose of this study was to compare the diagnostic accuracy of NGS, polymerase chain reaction (PCR), conventional culture, the Musculoskeletal Infection Society (MSIS) criteria, and the recently proposed criteria by Parvizi et al in the diagnosis of PJI.

A case is reported in which an epithelioid sarcoma developed in an apparently benign enchondroma or bone infarct at the site of a chrome-cobalt total knee replacement

1. Sixty-seven patients with subacute haematogenous osteomyelitis are reported. 2. The benign nature of the disease is noted. 3. The clinical types of infection are reported, with regard to the site of the lesion. 4. The treatment is described

The hand-foot syndrome is a benign self-limiting condition seen in young children with sickle-cell haemoglobinopathy, usually at the time of a crisis. The authors have observed 36 cases among 4920 patients. The features and management of the condition are discussed and the published literature is reviewed

1. A case of intraosseous lipoma is reported. 2. The literature on this tumour is reviewed and possible theories as to its pathogenesis are discussed. 3. It is concluded that the lesion is a true benign tumour which cannot be recognised with certainty without operation

Lipoma arborescens is a rare intra-articular lesion, characterised by diffuse replacement of the subsynovial tissue by mature fat cells, producing prominent villous transformation of the synovium. The aetiology of this benign condition is unknown. We describe six cases involving the knee discussing the symptoms, diagnosis and treatment

The problems of diagnosis and treatment of osteoclastoma are considered. The importance of full investigation, and the advantages of drill biopsy in confirming the diagnosis, are discussed. Treatment by radiation is believed to be better than treatment by surgical measures. Curettage and excision are unnecessary. Amputation for benign osteoclastoma is unjustifiable

1. Eight cases of solitary eosinophilic granuloma of bone are described, along with two possible complications. 2. The main pathological, clinical, and radiographic features of the condition, and its treatment, are discussed. 3. The essentially benign course of the solitary lesion, even in the presence of complications, is confirmed

Giant-cell tumour of the tendon sheath, also called pigmented villonodular synovitis, is a benign tumour with a high incidence of recurrence. We have tried to identify risk factors for recurrence. Of the 48 patients included in the study, 14 received radiotherapy after surgery. Only two (4%) had a recurrence. This compares favourably with previously reported incidences of between 25% and 45%

Glomus tumours are rare and benign, arising from a neuromyoarterial glomus body, most commonly in the hand. We report a patient with such a tumour in an atypical site, the right vastus lateralis. Pain was aggravated by muscle contraction, and ultrasonography and MRI were required to locate the lesion accurately. Surgical excision gave immediate pain relief

We describe three sisters in a family who presented with a clinical form of osteomesopycnosis which is a rare, benign osteosclerotic bone disorder limited to the axial skeleton. It must be distinguished from other osteosclerotic conditions which carry a worse prognosis. This is the first report of the condition in a Japanese family, and we believe it to be the first to be identified in Asian races

1. The clinical features in twenty cases of osteoid osteoma have been analysed and compared with other cases reported in the literature. 2. The lesion is regarded as a benign neoplasm and its unusual clinical behaviour is attributed to its vascular nature. 3. The frequency with which an erroneous diagnosis of "neurosis" is made is stressed

Two cases of benign osteoblastic tumours of the spine, occurring in young patients, and presenting as expanding osteolytic lesions with some central calcification and ossification, are described. It is suggested that they represent a condition allied to, but usefully separated from, osteoid osteoma of bone. The name osteogenic fibroma of bone, proposed by Lichtenstein for this type of case, is accepted

1. Clinical and histological features in ten patients with smooth muscle tumours of the limbs are described. 2. Severe pain and tenderness and the radiographic demonstration of calcification are useful pointers to the diagnosis. 3. Local recurrence of the tumour occurred in four patients despite apparently adequate excision. In three of these the tumours were shown histologically to be benign

1 . A case of parosteal osteoma with histologically low-grade sarcomatous areas is described. 2. Arteriography revealed abnormal arteries, the histological appearances of which are described. 3. Vascular shunts indicative of low-grade malignancy were also seen. 4. Reasons are given for accepting the view that this lesion is a tumour, originally benign, but liable to the development of low-grade malignancy
