EMG in Cubital Tunnel Syndrome
– EMG – General Discussion: – conduction velocity in the ulnar nerve across the elbow is slowed compared with the velocity in the forearm segment; – as noted by Kaempffe and Farbach (1998), abnormal EMG results are associated w/ poor surgical outcome; – position of elbow during EMG/NCS: … Read more
Electrical Burns
– See: Burn Management: – Discussion: – these burns are always much worse than they appear, and the big mistake is to underestimate their severity; – deeper tissues receive more damage and burn injury than superficial tissues; – consider using arteriography to help … Read more
Electrodiagnosis for CTS
– See: – Electromyography – Nerve Entrapment – Discussion: – it is difficult to determine which patients require preoperative EMG/NCS prior to carpal tunnel release; – consider applying this study in any patient involved in litigation, who falls under worker’s compensation, … Read more
Electromyography
– See: – Nerve Injury: – Nerve Menu – outside links: – The Expert Electromyographer – EMG Table of Contents – EMG Findings in Specific Conditions: – Normal Study: … Read more
Elbow Condylar Fractures
– Adult Condylar Fractures: (surgical technique) – capitellar and coronal shear frx – distal humerus frx: – lateral condyle frx: – medial condyle frx: – distal humeral non union: … Read more
Elbow Dislocations in Children
– See: Elbow Dislocations in Adults: – Discussion: – elbow dislocations in children are a relatively uncommon; – peak incidence occurs in adolescence between 11-15 years. – posterior dislocations are most common type; – posterior dislocation usually results from fall on outstretched hand w/ forarm supinated & … Read more
Elbow in RA Patient
– Discussion: – RA manifests itself in many ways in elbow joint, including nodules and bursae, synovitis, progressive joint destruction, antecubital cysts, & ulnar or, rarely posterior interosseous palsy; – note that involvement of the RA elbow is infrequently an isolated and therefore it is important to consider possible involvement in the wrist … Read more
Elbow Joint
– ROM: – normal flexion is from 0 to 150 deg of motion and 80 deg of pronation and supination; – functional range of motion is from 30-130 deg flexion and 50 deg of pronation-supination; – no tenderness, synovitis, swelling, subcutaneous nodules along the olecranon border (bursa), lateral/medial epicondyle; … Read more
Elbow Arthroscopy
– See Elbow Arthritis – Equipement: – 30 deg, 4 mm arthroscope; – arthroscopic pump; – Positioning: – patient is usually prone with sandbag placed under antecubital fossa; – TV monitor is positioned opposite of the patient; – ulnar nerve is palpated to pinpoint its location and to ensure that it does not subluxate with … Read more
