– See – Cubitbal Tunnel Syndrome – Differential Dx: Ulnar Nerve Dysfunction: – Martin Gruber Anastomosis – Ulnar Nerve Blocks: – Ulnar Nerve in Condylar Fractures: – Anatomy: – brachial plexus: – C8 and T1 nerve roots give rise to the medial cord which in turn, forms the ulnar nerve; – ulnar nerve passes distally, … Read more
– Discussion: – ulnar nerve blocks are used for frxs of little finger ray & in along w/ median and radial sensory blocks for ring finger ray fractures; – Anatomy: – ulnar nerve has two sensory branches that provide sensory innervation to ulnar side of the hand; – palmar … Read more
– Discussion: – see: elbow flexion contracture; – indicated for patients w/ loss of motion (out of functional range from 30 to 130 deg) due to anterior and posterior osteophytes; – PreOp Planning and Positioning: – patient is supine w/ bump placed under shoulder, and arm folded across chest; … Read more
(see also: Both Bone Forearm Fracture: / Ulnar Styloid Process) Anatomy radius & ulna lie parallel to each other when forearm is supinated; during pronation radius crosses ulna, rotating on axis that passes from capitulum through the distal end of ulna; ular side of wrist is supported by TFCC, which articulates w/ both lunate and triquetrium; … Read more
– See: – Vascular Problems of the Wrist and Hand: – Ulnar Artery in Forearm: – about 1 inch below the antecubital fossa, brachial artery divides into radial & ulnar arteries, w/ latter being larger; – paired venae comitantes accompany both radial & ulnar arteries; … Read more
– Discussion: – posterior cortex is disrupted w/ no cortical contact; – distal fragment is displaced posteriorly and proximally (by pull of triceps); – w/ medial displacement, the medial periosteal hinge is intact; – w/ lateral displacement, the lateral periosteal hinge is intact; – Physical Exam: … Read more
– See: – Tibial Plateau Frx Menu: Bicondylar Fractures and Type V Frx, Type IV Fractures, Total Depression Fracture – Discussion: – frx of medial tibial plateau (see total depression frx): – carries worst prognosis of all tibial plateau fractures; – 2 subsets of injury: … Read more
– Discussion: – if the frx needs a reduction, then the frx is not a type I but a type II; – posterior cortex remains intact, making it a greenstick frx; – technically a type II frx implies posterior displacement, but frequently there will also be medial impaction w/ … Read more
– Discussion: – frx is displaced & forearm is unstable in relation to humerus; – this injury is really a fracture-dislocation; – Avulsion Fracture – Comminuted Fractures – Distal Olecranon Fracture: … Read more
– Discussion: – displaced, stable frx; – frx fragments are displaced > 2-3 mm, but collateral ligaments are intact; – frx may be non-comminuted (Type IIA) or comminuted (Type IIB). – no sign of subluxation; – Non Operative Treatment: – immobilized in mid flexion, these … Read more
