Giant cell tumor (GCT) involving distal ulna being rare with reported rate of 0.45-3% of all GCT cases; the literature has only sporadic cases reported. Various treatment options have been proposed, and dilemma exist whether to do resection alone or resection combined with stabilization or reconstruction. Also, there is no conclusive evidence regarding the method of stabilization or reconstruct...

Pulmonary thromboembolism after distal ulna and radius fractures surgery: A case report a literature review

The sulcus of the extensor carpi ulnaris (ECU) tendon is located in the posterolateral aspect of the ulna in the groove between the head of the ulna and the ulnar styloid process. 6 This is well demonstrated in a crosssection through the cadaver wrist at the level of the distal radioulnar joint (Fig. 1). The ulnar styloid process of the ulna is always posterior to the head of the ulna. To evalu...

Height is fundamental to assessing growth and nutrition, calculating body surface area, and predicting pulmonary function in childhood. Its measurement is hindered by muscle weakness, joint, or spinal deformity. Arm span has been used as a substitute, but is inaccurate. The objective of the study was to identify a limb measurement that precisely and reproducibly predicts height in childhood. Ma...

Distal ulna fractures often concomitantly occur with distal radius fractures, and their treatment method is still controversial. We hypothesized that osteosynthesis is not necessary for distal radius fracture-associated distal ulna fracture without DRUJ surface fracture. In this study, non-operative treatment was selected for fractures not extending to the distal end of the ulna of the DRUJ bas...

OBJECTIVE To compare the biomechanical properties of cortical bone and surgical steel endoprosthesis for limb-sparing surgery of the distal radius in dogs and evaluate the role of the ulna in providing stability to the reconstructed limb. STUDY DESIGN Cadaveric biomechanical study. ANIMALS Twelve pairs of normal canine thoracic limbs. METHODS Paired limbs were divided into 4 groups: endop...

BACKGROUND AND OBJECTIVES Height is an essential measurement in clinical medicine. It allows the calculation of body mass index, ideal body weight, basic energy requirements and tidal volumes. In many patient groups, such as the critically ill, height cannot be measured easily and surrogate anthropometric measures are used. Regression equations estimating height are specific to ethnicity. We ai...

OBJECTIVE Identify radiographic risk factors for development of elbow dysplasia in giant breed dogs less than one year of age. METHODS Twenty-five giant breed puppies (Bernese Mountain dogs, English Mastiff, and Newfoundland) were studied. Both elbows of each dog were radiographed monthly from two to six months of age, then every other month until radial and ulnar physeal closure, followed tw...

This report describes a 6 year-old boy who was treated with one-bone forearm procedure for acquired pseudoarthrosis of the ulna combined with radial head dislocation after radical ulna debridement for osteomyelitis. At more than 20 years of follow-up, the patient had a nearly full range of elbow movements with a few additional surgical procedures. Pronation and supination was restricted by 45°,...

In this paper, based on the finite element method, stresses of radius and ulna are analyzed at different flexion angles elbow when playing tennis. The model is presented for position with 0°, 25°, 60°, 80° according to normal human arm bone. model, whole metacarpals, radius, ulna, humerus scapula considered. calculation simplified by setting metacarpals as rigid bodies using Tie binding constra...
