– See: Intrinsic Muscles of the Hand; – Origin: each from the 2 metacarpal bones between which it inserts; – Insertion: – superficial belly: – inserts onto the lateral tubercle at the base of the proximal phalanx (proximal phalanges of 2nd, 3rd, and 4th digits) to function as … Read more
– See: Plantar Muscles of the Foot: Origin: there are 4 dorsal interossei which arise by double pennate fibers from the bases and sides of the bodies of adjacent bones. Insertion: base of the proximal phalanx and aponeurosis of the tendons of the Extensor digitorum longus. The first dorsal interosseus (arising from the 1st an … Read more
(See also: brachial plexus) Anatomy dorsal scapular nerve to both rhomboids is typically derived from C5 neve close to intervertebral foramen and runs downward and backward thru or across surface of middle scalene, parallel to & below accessory nerve; it then passes medial to or thru levator scapulae (to which it may give a branch) and descends on the … Read more
– See Compartments: I, II, III, IV, V,VI and approach to the distal radius; – Technique: – straight dorsal incision centered over the wrist; – because the skin is loose over the dorsum of the wrist, contractures are uncommon; – incise skin and subcutaneous tissue down to the retinaculum; – careful to preserve dorsal veins and … Read more
– See: – Plating Techniques – Radial Shaft Fractures: Discussion – Discussion: – dorsolateral approach is best suited to frxs of proximal & middle thirds of radius as well as to address injury to proximal RU joint; – advantages: – … Read more
– Discussion: – w/ arm in external rotation, upper & lower borders of subscapularis can be visualized and palpated; – rotator cuff interval (soft spot) between supraspinatus & subscapularis is identified; – subscapularis tendon is tagged just shy of insertion; – subscapularis tendon and subajacent capsule are … Read more
– See: – Q angle – Malalignment of Patella – Discussion: – distal realignment procedures are chiefly indicated in pts w/ patellar subluxation, absence of hyper-laxity, and increased Q angle; – as pointed out by Fulkerson, et al (1990), less than 2% of patients w/ patellofemoral pain will require tibial tubercle transfer; – as noted … Read more
– See: – Adult Condylar Fractures – Distal Humeral Nonunion – Humeral Fractures – Non Operative Treatment: (cast bracing); – some orthopaedists do not feel that Holestein Lewis Frx are amenable to cast bracing; – some of these fractures are amenable to cast bracing and often elbow stiffness (most feared complication) is not a problem; … Read more
