Data Trace Editor – Discussion: – thickening of the medial capsular ligament attached proximally to adductor tubercle of femur and distally to tibia & posterior aspect of the capsule; – anatomically this is the third (deep) layer of the medial compartment; – parts of the distal arm: … Read more
– See: – Malgaigne Fracture – Sacral Fractures – Sacroiliac Fracture Dislocations – cresent fracture – Evaluation of Stability: – as noted by Kellam, et al. (1987), a stable injury is one that can withstand normal physiologic forces w/o excessive deformation; – it … Read more
– Discussion: – performed to correct equinus deformity at the ankle: – calcaneal (achilles) tendon is lengthened; – ankle joint capsule and all posterior tibiotalar, talofibular, & calcaneofibular ligaments are severed; – tibiofibular syndesmosis is released posteriorly; … Read more
– See: Autograft Discussion – PreOp Planning: – if patient has undergone previous bone graft harvests, consider CT scan to determine amount of remaining bone left in the crest; – Technique: – ensure that appropriately sized self retaining retractors are available; – straight longitudinal incision is made over posterior superior … Read more
Discussion: – the hyperextension phase of throwing may be the most important component of internal impingement; – in the late cocking position (abduction, external rotation, extension) may cause the postero-superior edge of the glenoid labrum to become caught between the humeral head and rotator cuff (surface of the infraspinatus and posterior fibers of supraspinatus tendon); – … Read more
– Anatomy: – this nerve is deep motor branch of radial nerve & supplies all of extrinsic wrist extensors except for the ECRL; – radial nerve enters the anterior compartment of the arm lying deeply between brachialis medially & BR & ECRL laterally; – PIN passes thru supinator muscle in its course from anterior to … Read more
Discussion trimalleolar fractures involve frx of the medial and lateral malleoli along w/ a frx of the posterior lip of tibial plafond; frx fragment results from avulsion by the posterior tibiofibular ligament at its site of attachment to the tibia; clinical results triamalleolar frxs are generally worse w/ larger fragments involving a larger portion of … Read more
– is derived from the Lumbrosacral Plexus – arises from posterior branches of S1, S2 & anterior branches of S2, S3; – travels thru greater sciatic foramen; – accompanies Sciatic Nerve in gluteal region; – continues downward in midline deep to the fascia lata, giving off branches that supply the skin of the posterior thigh.
– Discussion: – diagnosis: limb is shortened, internally rotated, and adducted; – Thompson and Epstein Classification: – Type I: w/ or w/o a minor fracture – Type II: w/ large single frx of post. acetabular rim; … Read more
– Associated with Inferior infarction – R.A.D. – usually associatted with an MI – Normal or Slightly widened QRS – S1 (small R in I), small Q3 – Note: Post HemiB may be associatted w/ R.B.B.B.; (may lead to AV blocks: Mobitz II) – Note: Lateral Infarction may cause R.A.D. – Must r/o: – Slender … Read more
