In 2012, there were 1,674 hospitalizations due to injury-related musculoskeletal conditions, roughly one-half the number of acute traumatic injuries requiring hospitalization. The most common types of injury-related musculoskeletal conditions leading to hospital admission were joint derangement (58%), followed by inflammation and pain due to overuse (23%). Joint derangement with neurological involvement accounted for another 12%. The vertebral column (including spine/back) was the most affected by injury-related musculoskeletal conditions (63%), followed by lower extremities (25%) and upper extremities (10%).

There was nearly twice the number of injury-related musculoskeletal conditions requiring outpatient visits as there were acute traumatic injuries. In 2012, there were a total of 413,466 outpatient visits for injury-related musculoskeletal conditions (710–739 ICD-9-CM series). Most outpatient visits for injury-related musculoskeletal conditions involved inflammation and pain due to overuse (87%). Lower extremities (44%) was the body region most often treated on an outpatient basis, followed by the vertebral column (including spine/back) at (34%), and upper extremities at 19%. The leading specific injury-related musculoskeletal conditions requiring outpatient treatment were inflammation and pain (overuse) to the knee and/or lower leg (20%), inflammation and pain (overuse) to the lumbar spine (18%), inflammation and pain (overuse) to the ankle and/or foot (14%), and inflammation and pain (overuse) to the shoulder (12%).
