Spontaneous displacement of olecranon fracture through geode salvaged by elbow replacement

Tocilizumab Was Effective in Repairing the Large Geode in a Patient with Rheumatoid Arthritis

Rheumatoid arthritis is characterized by multiple chronic arthritis subsequently inducing joint destruction. Although subchondral geode is a well-known feature of high-disease activity, a large geode is rare. Moreover, the treatment effect of biologic agents in the repair of large geode has not been reported. The present report shows the significant effect of interleukin-6 receptor blocker, tocilizumab, in repairing the large geode in the left humeral lateral epicondyle. This case implies that tocilizumab might be an effective treatment in patients with rheumatoid arthritis even with large geode.

Tumours and tumour mimics in the olecranon

Lesions in the olecranon are rare and may be identified during the investigation of a clinically suspected abnormality or as an incidental finding. This review describes the spectrum of tumours and tumour-like lesions that can involve the olecranon and illustrates the radiographic, CT, and MRI appearances that may facilitate diagnosis. A variety of pathological processes affecting the olecranon are presented and discussed including the epidemiology and imaging features.

Spontaneous talar and calcaneal fracture in rheumatoid arthritis: a case report

Rheumatoid arthritis (RA) leads to a progressive weakening of the skeleton which may result in bone fractures. However, spontaneous fractures (exclusive of stress fractures, vertebral collapse, and superficial articular fragmentation) in patients with rheumatoid arthritis have been only occasionally reported in the medical literature. A case of spontaneous talar and calcaneal fracture in rheumatoid arthritis is described. Bone lesions were identified on radiographs, MR images and scintigraphy in a patient with right ankle pain. The absence of episodes of acute trauma, and the presence of acute clinical manifestations should guide the clinical suspicion.
