Background: Giant cell tumor (GCT) of the bone is a benign neoplasm with local aggressive behavior. Distal ulna is a very rare place for GCT. Published studies have mainly focused on case reports, and thus there is no consistent treatment strategy for this tumor at this location. This retrospective study was conducted to evaluate the oncological and functional results of 2 di...

PURPOSE To measure the effects of distal radius malalignment on loading at the distal ulna. METHODS Using an adjustable mechanism to simulate angulated and translated malalignments, clinically relevant distal radius deformities were simulated in a cadaveric model. A custom-built load cell was inserted just proximal to the native ulna head to measure the resultant force and torque in the dista...

We aimed to determine the normal ranges of radial and ulnar deviation of the wrist in relation to the ulnar variance. A total of 102 healthy subjects (204 wrists) were included in the study. The ranges of radial and ulnar deviation of the wrists were measured using a universal goniometer. Ulnar variance was assessed manually or radiographically, and recorded as ulna minus, ulna plus or ulna min...

We have assessed the influence of isolated and combined rotational malunion of the radius and ulna on the rotation of the forearm. Osteotomies were made in both the radius and the ulna at the mid-diaphyseal level of five cadaver forearms and stabilised with intramedullary metal implants. Malunion about the axis of the respective forearm bone was produced at intervals of 10 degrees. The ranges o...

Giant-cell tumor of bone occurred in the distal end of the ulna is extremely uncommon. A 23-year-old male had a giant-cell tumor occurred in the distal end of the ulna. After wide resection of the distal segment of the ulna including giant-cell tumor, ulnar components of the wrist joint were reconstructed with modified Sauvé-Kapandji procedure using the iliac bone graft, preserving the triangul...

Giant cell tumor (GCT) of the distal end of the ulna is an uncommon site for primary bone tumors. When it occurs, en-bloc resection of the distal part of the ulna with or without reconstruction stabilization of the ulnar stump is the recommended treatment. We present a case of a 56-year-old man with a GCT of the distal ulna treated successfully with an en-bloc resection of the distal ulna with ...

During the diagnostic investigation of a patient with ulnar wrist pain, a hot spot in the proximal ulna was revealed on the technetium scintigram, which was found on radiographs to correspond to an osteolytic lesion in the proximal ulna. The lesion was resected and the histological diagnosis was an osteoblastoma. The wrist symptoms disappeared after resection of the lesion in the proximal ulna.

Different factors like fracture location and complexity, patient characteristics and surgical intervention are involved in the development of forearm bone non union [1,2]. Radius and ulna non-unions are usually associated with complex injury, inadequate initial reduction, unstable fixation. Anatomical and functional relationships between radius and ulna are so peculiar that it represents a soph...

BACKGROUND   Assessments of nutritional status frequently incorporate a measure of height to evaluate a person's relative thinness or fatness. Because height is often difficult to quantify, it may be predicted from alternative anthropometric measurements, including ulna length. Little information is available about the accuracy of these predictions in an ethnically diverse population. The prese...
