– Surgical Anatomy of Clubfoot: – contractures of ankle, subtalar, talonavicular, & calcaneocuboid joints; – forepart of foot is adducted & hind part of the foot is in varus angulation; – talus: – lies in a position of equinus, & its head is palpable … Read more
– Discussion: – anatomic variations: of tendons in 1st extensor compartment; – APL & EPB tendons may occupy separate canals, or lie together in one osseofibrous canal; – commonly there is one EPB and multiple APL; – there is separation of first extensor compartment more often in pts w/ DeQuervain’s tenosynovitis than in those w/o … Read more
– See: anterolateral approach to the ankle – Anatomy: – peroneus brevis is anterior to peroneus longus at level of ankle joint and is closer to lateral malleolus; (brevis is muscular almost down to the ankle); – flexor hallucis longus is most lateral of deep flexor muscles … Read more
– See: – Posterior Approach: – Lateral Approach – Position: – lateral w/ the arm abducted 90 deg; – force of gravity maintains the correct position; – sterile tourniquet is applied; – for simple fractures: supine with the arm laid across the chest; – … Read more
– Incision: – although the closed reduction may require external rotation of the hip, the initial incision is facilitated w/ slight internal rotation of the leg; – make straight lateral incision two finger breadths below the vastus ridge to a point 5-7 cm distally; – typically the … Read more
– Discussion: – when viewed in cross section, shape of distal femur resembles trapezoid w/ medial side inclinded about 25 deg & lateral side about 10 deg; – both the seating chisel and the subsequent blade plate should be 1 cm to 2 cm short of medial cortex … Read more
– Discussion: – has become standard technique for stabilizing types II & type III frx; – either two lateral pins, or one lateral and one medial pin may be used and both should penetrate the cortex; – medial and lateral pin insertion provides better stabilization; … Read more
– 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
– 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
– 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
