We treated a patient with tetraplegia who had paralysis of thumb and finger extension by transferring supinator motor branches to the posterior interosseous nerve. Surgery was performed bilaterally, 7 months after a spinal cord injury. Six months after surgery, with the wrist in neutral, extension of the thumb and finger were almost full, bilaterally. In(More)
OBJECT In C7-T1 palsies of the brachial plexus, shoulder and elbow function is preserved, but finger motion is absent. Finger flexion has been reconstructed using tendon or nerve transfers. Finger extension has been restored ineffectively by attaching the extensor tendons to the distal side of the dorsal radius (that is, tenodesis). In these types of nerve(More)
OBJECTIVE The pattern of triceps innervation is complex and, as yet, has not been fully elucidated. The purposes of this study were 1) to clarify the anatomy of the triceps motor branches, and 2) to evaluate their possible uses as a donor or receiver for nerve transfer. METHODS The radial nerve and its motor and cutaneous branches were bilaterally(More)
BACKGROUND The Mean Heart Rate (MHR) tends to decrease with age. When adjusted for gender and diseases, the magnitude of this effect is unclear. OBJECTIVES To analyze the MHR in a stratified sample of active and functionally independent individuals. METHODS A total of 1,172 patients aged > 40 years underwent Holter monitoring and were stratified by age(More)
OBJECT Grafting or nerve transfers to the axillary nerve have been performed using a deltopectoral approach and/or a posterior arm approach. In this report, the surgical anatomy of the axillary nerve was studied with the goal of repairing the nerve through an axillary access. METHODS The axillary nerve was bilaterally dissected in 10 embalmed cadavers to(More)
BACKGROUND Acute coronary syndrome (ACS) is one of the main causes of morbidity and mortality in the modern world. A sedentary lifestyle, present in 85% of the Brazilian population, is considered a risk factor for the development of coronary artery disease. However, the correlation of a sedentary lifestyle with cardiovascular events (CVE) during(More)
BACKGROUND According to some international studies, patients with acute coronary syndrome (ACS) and increased left atrial volume index (LAVI) have worse long-term prognosis. However, national Brazilian studies confirming this prediction are still lacking. OBJECTIVE To evaluate LAVI as a predictor of major cardiovascular events (MCE) in patients with ACS(More)
