A 23-year-old man injured his left knee. A CT scan showed a dislocation of the proximal tibiofibular joint. Closed reduction of the dislocation was done successfully under procedural sedation and analgesia. Afterwards he was treated with a pressure bandage and immobilisation of the knee for 2 weeks.

Introduction Sudden thrombosis of an abdominal aortic aneurysm is a rare condition with a high mortality rate. Report We present a patient with acute neurological deficits in both legs based on a thrombosis of a nine centimetre infrarenal abdominal aortic aneurysm. Successful iliac thrombectomy with aortic tube graft reconstruction was performed. Discussion Sudden thrombosis of an abdominal aortic aneurysm is a rare condition, but should be taken into consideration in patients with acute neurological deficits of the lower extremities. Prompt diagnosis and surgical management can lead to a successful outcome. A review of the literature is presented.

Gastro-intestinal stromal tumour (GIST) is increasingly recognized as a distinct entity within the group of soft tissue tumours. Mostly, GIST arises from the muscular components of the stromal layer, but the tumour may also originate from the autonomic nerve system, recently designated as gastro-intestinal autonomic nerve tumour (GANT). The majority of GIST is located in the stomach and small intestine; only 4% of GIST is found in the duodenum. Clinical and pathological criteria to differentiate benign from malignant GIST are not well established. Tumour size and mitotic activity are commonly considered as important features, predicting biological behaviour and outcome. It has been suggested that the clinical course of the GANT-type tumours may be more aggressive. We present a case of a radically resected duodenal stromal tumour with benign features, in a young woman, with metastases to the liver and peritoneum occurring 8 years after the initial diagnosis.

Background Hip fracture patients often have an impaired nutritional status at the time of fracture, which can result in a higher complication rate, prolonged rehabilitation time and increased mortality. A study was designed to evaluate the effect of nutritional intervention on nutritional status, functional status, total length of stay, postoperative complications and cost-effectiveness. Methods Open-labelled, multi-centre, randomized controlled trial in hip fracture patients aged 55 years and above. The intervention group receives dietetic counselling (by regular home visits and telephone calls) and oral nutritional supplementation for three months after surgery. The control group receives usual dietetic care as provided by the hospital. Outcome assessment is performed at three and six months after hip fracture. Discussion Patient recruitment has started in July 2007 and has ended in December 2009. First results are expected in 2011. Trial registration ClinicalTrials.gov NCT00523575
