Fatigue strength of common tibial intramedullary nail distal locking screws.

Background: Premature failure of either the nail and/or locking screws with unstable fracture patterns may lead to angulation, shortening, malunion, and IM nail migration. Up to thirty percent of all unreamed nail locking screws can break after initial weight bearing is allowed at 8-10 weeks if union has not occurred. The primary problem this presents is hardware removal during revision surgery.

Rhabdomyolysis attributable to severe overuse of the supraspinatus muscle: a report of two cases.

Rhabdomyolysis can occur after overuse of or injury to any muscle. This results in cell membrane compromise and the escape of cellular contents into the extracellular fluid. After strenuous exercise, a small amount of rhabdomyolysis normally occurs but is usually self-limited and does not progress to compartment syndrome.
