PURPOSE This study estimated the incidence and cost of both acute and overuse pectoralis major muscle or tendon PMMPMT injuries among Active Duty Army Soldiers. WHY Though relatively rare, an increase in PMMPMT ruptures has been attributed to the growing popularity in weight training since these injuries are primarily caused by the bench press. Less severe PMMPMT strains and overuse injuries are also expected to be increasing. To assess future injury prevention initiatives, a standard method for monitoring these injuries was needed. HOW CY 2016 PMMPMT injury visits were estimated by identifying medical diagnosis codes compatible with a PMMPMT diagnosis in Soldiers medical records. Based on a clinical review of medical records 100 percent of hospitalizations, 10 percent of outpatient, code-specific probabilities were used to assign weight factors to all diagnoses to estimate injury frequencies and direct medical costs. Indirect costs were estimated using Soldier average pay rates. RESULTS Five male Soldiers ages 20 to 25 were hospitalized, and an estimated 2,763 Soldiers 87 percent male ages 25 to 44 had outpatient visits for a PMMPMT. Soldiers averaged five medical visits per injury. Direct hospitalization cost 70,962 was less than 4 percent of the estimated outpatient cost 1,818,144. Total cost direct and indirect based on estimated 166,380 days of lost or restricted worktime was 57 million. CONCLUSION PMMPMT injuries include not only ruptures requiring surgical repair, but an even greater number of injuries treated through outpatient services. These preventable musculoskeletal injuries are costly and can result in long durations of lost or restricted worktime. Since PMMPMT injuries are primarily attributed to the bench press, which is not a required soldier training activity, prevention includes avoidance through alternative weight-training exercises and adherence to proper technique.
