In 2012, there were 3,093 acute traumatic injuries (coded in the 800–900 ICD-9-CM code series) requiring hospitalization. Leading specific reasons for hospitalizations included fractures of the lower leg and/or ankle (13 %), facial fracture (6%), and fracture of the foot/toes (3%). Comparing all body regions, the lower extremity accounted for 30%, the upper extremity for 19%, and the head for 16%. Within the head region, traumatic brain injury, including skull fracture, accounted for 15%, and other specified head injuries accounted for less than 1%. (Reference Table 6D.1 PDF [1] CSV [2])

During the same year, US Army active duty, nondeployed soldiers incurred 240,299 acute traumatic injuries (coded in the 800–900 ICD-9-CM code series) for which outpatient care was required. Leading specific reasons for outpatient visits included strains/sprains to the lower leg and/or ankle (9%) and strains/sprains of the shoulder/upper arm (7%). Body regions most affected were lower extremities (38%), upper extremities (26%), and the head and neck region (TBI and other head, face, and neck) (11%). (Reference Table 6D.2 PDF [3] CSV [4])

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%). (Reference Table 6D.3 PDF [5] CSV [6])

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%).
