Suprascapular Nerve
– Anatomy: – suprascapular nerve is derived from upper trunk of brachial plexus, typically receiving fibers from C5 and C6; – it contains both motor and sensory components, and sends sensory branches to both the glenohumeral and AC joints, but does not innervate the skin; – it passes downward, laterally (deep to the omohyoid and … Read more
Supraspinatus Muscle
– See: – Abductors of the Shoulder: – Rotator cuff; – Anatomy: – origin: medial 2/3 of supraspinatus fossa above spine of scapula; – insertion: superior surface of greater tuberosity of humerus and capsule of shoulder joint; – demensions: supraspinatus averages 25 mm wide and has … Read more
Sural Artery
– See: Sural nerve: – Anatomy: – arises from popliteal artery or from sural artery; – it runs adjacent to Sural Nerve, & regularly giving off small branches to it; – it gives off a branch to skin that supplies upper part of the calf, which corresponds to the … Read more
Supination and Pronation of Foot
– Supination: – supination of foot is a combination of inward rotation at the ankle, adduction of the hindfoot, inversion of the forefoot, and medial arch elevation; – subtalar joint supination is 3 planes of motion simultaneously: – adduction – inversion … Read more
Supination External Rotation Ankle Frx (Weber B)
– Discussion: – supination external rotation fractures are the equivalent of Weber B frx; – it is the most common type of frx of fibula is caused by supination and external rotation, resulting in oblique frx at level of sydesmosis – supination of foot is combination … Read more
Supination External Rotation Frx in Children
– See: Adult SER Frx – Stage I: – SH II frx of distal tibial physes w/ long spiral frx of distal tibia, which starts laterally at the growth plate, and progresses medially, proximally, and posteriorly; – metaphyseal fragment is localized posterio-medially; – on lateral radiographs, … Read more
Supracondylar Femoral Fractures
– See: – Distal Femoral Shaft Fractures – Distal Femoral Phyeal Frx – Supracondylar Fractures following TKR – Discussion: – work up for femur fracture – mechanism: axial load to a flexed knee; – Bimodal distribution: – low energy fractures involving older females (often have severe osteoporosis); – high energy fractures involving younger males; – associated … Read more
Supracondylar Femoral Frx: Operative Treatment
– Pertinent Surgical Anatomy – Operative Treatment: Choice of Hardware: – 95 deg. condylar blade plate: – dynamic screw and side plate: – condylar buttress plate: – IM nails for supracondylar fractures: – zickel nail: – may be used for extra-articular … Read more
