We present two sporadic cases of complete ulnar hemimelia, a rare congenital defect. In one case, ulnar hemimelia was associated with tridactyly and elbow malrotation with radiohumeral synostosis; in the second case, ulnar hemimelia was assciated with mono-metacarpal bidactyly and anterior cubital webbing of the elbow with fixed flexion. To the best of our knowledge, there is dearth of informat...

Anterior, subcutaneous ulnar nerve transposition decompresses the ulnar nerve and, by transposing anterior to the medial epicondyle, eliminates longitudinal traction forces applied to the nerve during elbow flexion. This article reviews the indications and contraindications of the technique and describes the surgical technique in detail.

seven patients who had intractable pain of the pelvis and lower extremities were scheduled for cordotomy of the spinothalamic tracts after preliminary investigations. in three patients laminectomy was performed, to approach the anterior portion of the spinal cord, anil in the rest anterior cordotomy was performed with anterior disectomy under direct vision of the spinal cord. it appears that an...

CONTEXT Lesions of the anterior interosseous nerve are rare and comprise less than 1% of all upper extremity nerve palsies. Traumatic causes include blunt trauma, forearm fractures, penetrating injury and local pressure from a plaster cast, but has never before been described in association with crutch use. This is the first reported case of the use of elbow crutches causing symptomatic anterio...

Ulnar nerve neuropathy at the elbow represents the second most frequent compression neuropathy of the upper extremity. Of the five different anatomical areas responsible for ulnar nerve compression at the elbow region, the epitrochlear-olecranon channel and Osborne’s arcade are the most common. An additional cause of nerve damage is a dynamic process in which the ulnar nerve dislocates anterior...

Previous studies in neurologically intact subjects have shown that motor coordination can be described by task-dependent combinations of a few muscle synergies, defined here as a fixed pattern of activation across a set of muscles. Arm function in severely impaired stroke survivors is characterized by stereotypical postural and movement patterns involving the shoulder and elbow. Accordingly, we...

INTRODUCTION In the functional range of elbow flexion (approximately 20 to 120) the anterior bundle of the Ulnar Collateral Ligament (UCL) has been shown to function as the primary stabilizer against valgus stresses [1,2]. Injuries to this ligament are common among throwing athletes. Surgical reconstruction of the UCL is frequently performed using the Docking technique [3] and has achieved succ...
