Disseminated amyloidosis presenting with right proximal femur pathological fracture in a haemodialysis end-stage renal failure patient.

Osteoarticular amyloidosis can be one of the musculoskeletal system manifestations related to dialysis. We share our experience in dealing with a case of disseminated haemodialysis-associated amyloidosis in a 74-year-old end-stage renal failure patient. This patient suffered from a serious complication, namely an unprovoked pathological fracture at the basal neck region of the right femur. Polyarticular cystic and lytic lesions over the contralateral proximal femur, bilateral proximal humerus and the right lunate were noted on further imaging. In view of extensive amyloidotic infiltration into the proximal femur as well as the acetabulum, a cemented total hip arthroplasty operation was performed for pain relief and restoration of function. The radiological investigations, diagnostic challenges, operative as well as histopathological findings are discussed. This disease should be considered in the differential diagnosis of pathological juxta-articular fracture in patients undergoing haemodialysis.

Robot-assisted excision of ectopic mediastinal parathyroid adenoma.

Robot-assisted excision of an ectopic parathyroid adenoma in the superior mediastinum was performed in a 57-year-old man. The mass was located by methoxyisobutylisonitrile scan and computed tomography. Identification of the ectopic parathyroid adenoma was facilitated by the 3-dimensional images of the da Vinci robotic system, and resection was achieved using EndoWrist instruments. Robot-assisted excision of parathyroid adenoma located in the relatively inaccessible superior mediastinum proved to be feasible.

Video-assisted thoracic surgery excision of mediastinal hemangioma.

A 62-year-old woman with a middle mediastinal hemangioma was successfully treated using a video-assisted thoracic surgery approach facilitated by segmental rib resection, despite an initial radiological study that showed encasement by the surrounding great vessels. Pathological examination confirmed a cavernous hemangioma. This approach offers potential resection in difficult cases of mediastinal tumor.

Unusual traumatic triceps tendon avulsion rupture: a word of caution.

Triceps tendon rupture is a rare condition. The usual mechanism of injury is a fall on an outstretched hand, although direct contact injuries have also been reported to cause this injury. A 67-year-old woman presented with injuries caused by direct impact to her right elbow after a fall. X-rays of the elbow demonstrated the cardinal clinical 'gap' and 'flake' signs. It is necessary to be aware of this injury and perform a careful examination at the time of the initial presentation, as the signs of this injury are usually subtle. Most reported primary repairs have been performed with non-absorbable transosseous sutures. In this case report, we show how using suture anchors for reattachment is a technically feasible alternative operative method providing a good surgical outcome.
