– 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
– 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
– 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
– 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
– Discusison: – traditionally used for the inflow cannula; – note that with modern pump equipment, the inflow canula is generally no necessary; – technique: – place this cannula under direct visualization so that the cannula will not be placed under a plicae or into a thick wad of … Read more
– See: – Lateral Compartment – Anterior Compart – Deep Posterior Compartment – Discussion: – superficial posterior compartment contians gastrocnemius, soleus, popliteus, & plantaris muscles. – sural nerve, short & long saphenous veins are also w/in this compartment, but there are no … 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
– See: Bone Healing w/ Plates – Discussion: – useful in subtrochanteric frxs since it permits insertion of at least two cortical screws into proximal fragment (calcar); – having multiple points of fixation above and below the fracture prevents varus or rotational migration; … Read more
