1/3. Archery-related injuries of the hand, forearm, and elbow.The five patients reported herein had various archery-related injuries of the upper extremities. Acute injuries included arrow laceration of a digital nerve and artery, contusion of forearm skin and subcutaneous tissue, and compression neuropathy of digital nerves from the bowstring. Chronic injuries included bilateral medial epicondylitis and median nerve compression at the wrist, de Quervain's tenosynovitis, and median nerve compression at the elbow. Essential measures for archery safety include use of archery protective gear, use of a light-weight bow, conditioning of the forearm flexor muscles, and modifications in drawing the bowstring.- - - - - - - - - - ranking = 1keywords = safety (Clic here for more details about this article) |
2/3. Automotive airbag-related upper extremity injuries: a report of three cases.Automotive airbag technology has reduced the number of injuries and fatalities resulting from motor vehicle crashes. With the increasingly frequent application of this safety feature in automobiles, recent reports of airbag-associated injuries have emerged, including ocular and non-lethal cardiac trauma. We report three cases of airbag-related upper extremity injuries seen at a level-I trauma center over a 6-month period. A heightened awareness of this type of injury in patients injured in motor vehicle crashes with airbag deployment is recommended. The awareness, identification, and management of these high energy injuries will take on added meaning as the airbag technology becomes universally applied.- - - - - - - - - - ranking = 1keywords = safety (Clic here for more details about this article) |
3/3. safety belt restraints and compartment intrusions in frontal and lateral motor vehicle crashes: mechanisms of injuries, complications, and acute care costs.A 3-year prospective study examined 76 frontal (F) and 45 lateral (L) motor vehicle crash (MVC) patients with regard to seatbelt restraint use and occupant compartment contact and intrusion injuries. These 121 MVC victims with multiple injuries (39 belted [B] and 82 non-belted [NB]), admitted to a level I trauma center, were studied by accident reconstruction and medical data analysis. They had a MVC mean impact velocity (delta V) of 30 /- 11 mph and an injury Severity Score of 29 /- 12. Proper restraint use reduced brain injury in F MVCs (30% FB vs. 47% FNB) but had no effect in L MVCs (63% LB vs. 30% FB [p < 0.06]). Belt use did not protect against lung, liver, spleen, pelvis, or lower extremity (LE) injury. These appeared to be more a function of crash direction, with LE injuries higher in F crashes (p < 0.04) and pelvis injuries (p < 0.001) higher in L crashes. In FB crashes, however, properly used safety restraints were the primary cause of bowel or colon injuries (p < 0.006). Belts did not prevent thoracic or abdominal solid organ injuries in L crashes. Contact-intrusions (CI) of the car occupant compartment in F crashes were the main cause of brain (A-pillar), lung and liver (steering wheel and instrument panel), and LE (toepan) injuries; but in L crashes, side-door CI caused lung, aorta, liver, and pelvic injuries. In contrast, contact-only (CO) injuries of the steering assembly were mainly responsible for injuries to the lung, heart, and liver in F crashes, and side-door CO for lung, liver, and spleen injuries in L crashes. Deaths and complications after injury were higher among F MVC occupants, or when delta V was > or = 30 mph. Hospital and professional costs reflect the complex care needed for victims of multiple injuries: FB, $99,000; FNB, $95,000; LB, $75,000; LNB, $79,000; total, $10.7 million. Present vehicle safety standards are not adequate, and structural design changes are needed to improve restraints and protect occupants from intrusion-related injuries.- - - - - - - - - - ranking = 2keywords = safety (Clic here for more details about this article) |
