The purpose of this study was to assess the stability of a developmental pelvic reconstruction system which extends the concept of triangular osteosynthesis with fixation anterior to the lumbosacral pivot point. An unstable Tile type-C fracture, associated with a sacral transforaminal fracture, was created in synthetic pelves. The new concept was compared(More)
We describe 22 cases of bizarre parosteal osteochondromatous proliferation, or Nora's lesion. These are surface-based osteocartilaginous lesions typically affecting the hands and feet. All patients were identified from the records of a regional bone tumour unit and were treated between 1985 and 2009. Nine lesions involved the metacarpals, seven the(More)
The treatment of a congenital venous malformation using endovenous radiofrequency ablation in a patient is described. The patient initially underwent two treatments of foam sclerotherapy with moderate success. Later the main feeding vessel of the venous malformation became evident on examination with venous duplex and was identified as the great saphenous(More)
OBJECTIVES Otitis media with effusion (OME) is the most common disease after viral infections of upper respiratory tract (URTI) in children. Studies indicate the important role of nitric oxide (NO) in the etiology of hearing loss. However, there is no study that focuses on the role of nitric oxide synthase (eNOS) polymorphisms in the cases with OME. The aim(More)
The aim of acetabular fracture fixation is to restore joint congruity with restoration of the articular surface. Poor outcomes are seen where this has not been achieved. Letournel reported a collarette osteophyte seen postoperatively in a proportion of patients, which he suggested was an early precursor to the development of osteoarthritis. This is a(More)
The safety of treating low-grade chondral tumours by primary surgery without a pre- operative diagnostic needle biopsy was assessed by looking at the concordance between radiological and histological diagnoses. A retrospective review of the departmental histopathology registry from 2005 to 2009 was performed to identify cases of intramedullary chondral(More)
This case report describes the successful use of a novel "conservative hip replacement" in conditions precluding the use of a standard total hip arthroplasty in a 70-year-old man. The femoral canal was occluded because of previous surgery for a bone tumor in the subtrochanteric region. The patient continues to do well at 4 years with minimal discomfort. At(More)
The aim of this study was to establish whether the proximity of significant neurovascular structures around the surgical excision results in higher rates of recurrence and poorer survival outcomes. A retrospective study of all patients treated at a regional bone tumour unit for proximal fibula Ewing's tumours and osteosarcomas was conducted, and in total 17(More)
