Medical and Economic Parameters of Motorcycle-induced Trauma.BRIED JAMES M. M.D.; CORDASCO, FRANK A. M.D.; VOLZ, ROBERT G. M.D., F.A.C.S.Clinical Orthopaedics and Related Research (1976-2007): October 1987 Buy Abstract A retrospective study was conducted on all patients injured in a motorcycle accident who were admitted to the authors' institution during a oneyear period. The 71 patients evaluated averaged 26 years of age; 79% were men, 75% were not wearing a helmet, and 24% were legally intoxicated. Sixty-six percent required surgical intervention and 36% a second procedure. There were 167 fractures, with an average of 2.4 per patient. The 27 patients requiring a blood transfusion averaged 10.5 units per patient. Motorcyclists not wearing a helmet had an increased risk of head injury (p < .01). Those with head injuries had an increased need for intensive care (p < .0001) and a ventilator (p < .001). Patients with head injuries more commonly sustained fractures about the shoulder (p < .015) than fractures to the lower extremity (p < .005). The average hospital stay was 13 days, with a cost of $16,408 per patient. The cost was significantly higher in patients with a head injury ($21,945) than in patients without a head injury ($11,941). Patients sustaining a head injury were less likely to return to baseline functioning (p < .001). (C) Lippincott-Raven Publishers.
