Dr. Guten uses his experience as medical director of the Sports Medicine Institute at Sinai Samaritan Medical Center in Milwaukee and as an orthopaedic surgeon to provide readers with an easy-to-follow guide to use in conjunction with their doctor for understanding, preventing, and treating injuries sustained during activity. His Stop, Caution, Go system summarizes ten recommendations for each of the common injuries suffered in outdoor recreation, from herniated neck disks to stress fractures of the foot. Recommendations are given for: activity level, alternative activities, rehabilitation exercises, appropriate support, use of ice or heat, medication, equipment, nutrition, fluids, and surfaces used for exercise. Forty injuries common to participants in hiking, backpacking, bicycling, trail running, rock climbing, mountaineering, paddling, skiing, and surfing are discussed and analyzed. This guide covers common injuries associated with outdoor adventure activities, such as: Ulnar nueritis (biking) Anterior cruciate ligament tear (skiing) Osteoarthritis of the knee and lumbar back strain (hiking) Finger tendonitis (climbing) Shoulder rotator cuff tendonitis (kayaking) Knee-torn meniscus (surfing)
