– Discussion: – coronoid helps to resist varus stress and posterior elbow subluxation (radial head also resists posterior subluxation); – pivotal role as an anterior buttress; – at least 50% of the coronoid must be present for the ulno-humeral joint to have normal function (i.e., for joint to be stable); … Read more
– Hematoma: – Infection associated with hematoma formation after shoulder arthroplasty – Fractures – fractures may occur at the tip of the prosthesis; – long oblique and spiral fractures can be treated non operatively as long as good alignment is maintained; – transverse or short oblique fractures may not … Read more
– Discussion: – dislocations of the elbow associated with fracture are termed complex; – comprimise 49% of elbow dislocations; – most of these fractures are inherently unstable and require surgery; – prolonged elbow immobilization produces poor results. – surgery must achieve sufficient stability to allow … Read more
