Fracture of Radius, Ulna, and Humerus Elizabeth Travis Michael Snyder AH 322 10-22-03 Causes of Radius and Ulna Fractures Falling on outstretched arm Direct blow Mountain biking Skateboarding Trauma Automobile accidents Child abuse Types of Fractures Nightstick fracture Monteggia fracture Defined as an isolated midshaft ulnar fracture Defined as a fracture of the ulna (usually proximal one third) with dislocation of the radial head. Galeazzi fracture Defined as a fracture of the distal one third of the radius with dislocation of the distal radioulnar joint (DRUJ). Types Cont. It is also known as a reverse Monteggia fracture. Essex-Lopresti fracture This is defined as a fracture of the radial head and dislocation of DRUJ, with partial or complete disruption of radioulnar interosseous membrane. Types Cont. Closed The bone is broken, but the skin is not lacerated. Open or simple fracture or compound fracture The skin may be pierced by the bone or by a blow that breaks the skin at the time of the fracture The bone may or may not be visible in the wound. Types Cont. Transverse The fracture is at right angles to the long axis of the bone. Greenstick fracture fracture Fracture on one side of the bone, causing a bend on the other side of the bone. Comminuted fracture A fracture that results in three or more bone fragments. Types Cont. Signs and Symptoms Most of the time you will know if you have a broken arm Snap or cracking sound Area will be tender and swollen Obvious deformity Decreased sensation or inability to move the limb, which may indicate nerve damage Treatment External plaster and fiberglass casts cast-braces splints Internal fixation methods fixation methods metal plates Pins screws VOLAR ELBOW Treatment Cont’ Keep your splint or cast clean and dry If possible, apply ice 2-3 times a day Keep your arm elevated above the heart as much as possible to decrease swelling Take pain medicine as prescribed Prognosis Earlier treatment usually improves results Fractures in younger children and adolescents tend to heal better Fractures that have multiple breaks, involve a joint, have open wounds, or become infected could have healing complications. Prognosis Cont’ Older adults have increased chance of losing some ability or movement in the broken arm. Chronic diseases such as osteoporosis and diabetes may slow the healing process. Prevention Wear appropriate personal safety equipment as protection. Wear car seat belts Use wrist guards for in-line skating and skateboarding Wear appropriate pads for contact sports Prevent and treat osteoporosis References http://orthoinfo.aaos.org/fact/thr_report.cfm ?Thread_ID=326&topcategory=Arm Huang, Enoch MD, MPH, Grims, Peter MD “Forearm Fractures” Baniukiewied, Andrew P.
