– See: – Phalangeal Injury – Thumb Swan Neck Deformity – Transverse Retinacular Ligament – Discussion: – deformity involves hyperextension of PIP Joint w/ flexion of DIP joint; – deformity may start at either the PIP or DIP; – at PIP joint, there … Read more
– See: – Incision: – skin incision begins on mid-lateral aspect of the ulnar side of the thumb, is curved over the MP joint, and extends proximally just ulnar to the EPL tendon; – take care to identify branches of the superfical radial nerve at the proximal aspect of … Read more
– See: Anterior Approach to Shoulder and Synthes Proximal Humerus Products – Operative Treatment Options: – Lateral Plating (Locking Plating): – Percutaneous Pinning – Screw Tension Band Technique: – reduction: – in some cases cancellous bone from the … Read more
– Main Menu: – PreOp Planning – radiographs and templating – Surgical Exposure: – Patient Positioning, Preping, Draping – Anterior Longitudinal Midline Approach – Deep Articular Exposure – Patellar Eversion: – Patella: – patellar resurfacing – prior to patellar resurfacing, determine the propensity for the native patella to subluxate; – if subluxation is present (tibial component … Read more
– Preoperative Considerations: – radiographs – open ankle fractures – fracture dislocations of the ankle – trimalleolar frx: – in these fractures, consider a posterior approach using an antiglide plate which allows for direct fixation of the posterior mallleolar frx (w/ screws inserted from posterior … Read more
– Position: – beach chair position; – position should allows full shouler extension, exernal and internal rotation (note that the posterior cuff will be brought into the operative field by extending and internally rotating the shoulder – which is acomplished by pinning the patient’s arm between the OR table … Read more
– See: – Discussion: – consider 90 deg of flexion in splint for 4 days, then begin CPM; – need to start early motion; – look for late varus collapse of knee; – attempt to ambulate at 2-4 days, & consider FWB at 3-6 months; … 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: Deep Palmar Arch – Discussion: – superficial arch is much larger & important than the deep arch – classical complete arch present in only 34% (from radial & ulnar) – variations: – entirely from the ulnar artery in … Read more
– See: proximal femoral shaft fractures / – Discussion: – definition: – between lesser trochanter and 5 cm distal, even as far as center of isthmus of the femoral shaft; – technically starts below the lesser tuberosity; – medial and posteromedial cortex is a site of high compressive forces, while lateral cortex experiences high tensile stresses (forces … Read more
