Data Trace Editor Foot Ankle Int. 1994 Jun;15(6):293-296 Dohm M, Purdy BA, Benjamin J ABSTRACT BACKGROUND: A review of 37 ankle arthrodesis procedures done over a 12-year period by multiple surgeons at a single institution was performed. METHODS: Six different techniques were used during the study period. RESULTS: The initial success rate, defined … Read more
– Discussion: – posterior talofibular ligament arises from the nonarticular surface of posteromedial Fibula & inserts onto lateral tubercle of talus; – it is strongest of the lateral ligaments; – prevents posterior and rotatory subluxation of the talus; – fibers are oriented horizontally, & tensed only in … Read more
– See: Anterior Tibial Artery – Discussion: – posterior tibial artery enters posterior compartment of leg lying posterior to tibialis posterior & enters plantar foot after passing behind medial malleolus; – largest branch is peroneal artery arising high in leg and coursing downward in posterior compartment, lying just medial to fibula; – gives off branches to … Read more
– See: Lateral Approach – Discussion: – allows exposure of the entire distal humerus as well as radial head, radial neck, and biceps tuberosity; – indications for this approach include frxs of distal humerus, old posterior elbow dislocations, radial head frx, radial head excisions, arthroplasties, fixation of distal biceps tendon rupture, and … Read more
– Discussion: – allows access for ORIF of fractures of ankle w/ frx of posterior tibial lip; – allows access for removal of osteochondritis dissecans fragments from lateral part of dome of talus and for osteochondromatosis of ankle; – Incision: – begin incision about 12 cm proximal to tip of … Read more
– See: – tibial component – proximal tibial cut – extra-medullary cutting guide; – Discussion: – viewed in saggital plane, line drawn between anterior & posterior rims of the tibial plateaus is approx 10 deg posteriorly; – this radiographic tilt does not take the menisci into … Read more
– See: – Biomechanics of TKR – Joint Line Position – PCL Retaining TKR – Discussion: – cruciate ligaments are needed for running atheletes, but are not as important to resist forces in thesagittal plane in reconstructed arthritic knee; – theoretically, PCL-substituting TKR allow exposure & ligament correction of PCL-sacrificing prosthesis while reproducing kinematic effects of PCL; … Read more
– See: Kocher Langenbock for Acetabular Frx – Discussion: – position pt prone, on a radiolucent table; – vertical incision placed 2 cm lateral to posterosuperior spine; – mobilize gluteal muscles from their origins on iliac wing & sacrum; – mobilize piriformis from greater sciatic notch to … 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
