The complications related to surgery to treat VEO are similar to any open or arthroscopic procedure on the elbow: damage to neurovascular structures either by direct injury or by the compressive phenomenon of fluid extravasation, damage to articular surfaces from instrumentation, infection, breakage of instruments, or tourniquet-related problems. The other complication is formation of early heterotopic bone or scar tissue in the posterior compartment in a small percentage (less than 10%) of patients. This complication often occurs when the recovery period is accelerated and early throwing is pushed. Damage to neurovascular structures is the most common complication of elbow arthroscopy.28 Thus, the surgeon must have a thorough knowledge of the technique and of elbow anatomy as seen during arthroscopic surgery.
