During the 14-year period of 1971-1985, 368 stress fractures in 324 athletes were treated. The series contained 268 fractures in males and 100 fractures in females; 32 fractures occurred in children (less than 16 years), 117 in adolescents (16-19 years), and 219 in adults. Forty-six fractures were incurred by athletes at an international level, 274 by(More)
Pre-exercise stretching and adequate warm-up are important in the prevention of hamstring injuries. A previous mild injury or fatigue may increase the risk of injury. Hamstring muscle tear is typically partial and takes place during eccentric exercise when the muscle develops tension while lengthening, but variation in injury mechanisms is possible.(More)
A new clinical scoring system, including subjective assessment of symptoms and evaluation of ankle range of motion and isokinetic measurement of ankle plantar flexion and dorsiflexion strengths, is presented in 101 patients (86 men, 15 women) who had repair of a closed Achilles tendon rupture. Twenty-one patients were competitive athletes and 70 were(More)
OBJECTIVE To determine the acute injury profile in each of six sports and compare the injury rates between the sports. DESIGN Analysis of national sports injury insurance registry data. SETTING Finland during 1987-91. SUBJECTS 621,691 person years of exposure among participants in soccer, ice hockey, volleyball, basketball, judo, or karate. MAIN(More)
BACKGROUND Hamstring injuries are common especially in athletes. Partial and complete tears of the proximal origin may cause pain and functional loss. OBJECTIVE To evaluate the results of surgical treatment for partial proximal hamstring tears. METHODS Between 1994 and 2005, 47 athletes (48 cases, 1 bilateral) with partial proximal hamstring tears were(More)
We treated eight patients who had complete rupture of the ischial origin of the hamstring muscles. This uncommon injury results from a sudden forceful flexion of the hip joint when the knee is extended and the hamstring muscles powerfully contracted. The injuries occurred during athletic exercise in six men and two women who had a mean age of 40 years(More)
We analyzed the complications after surgical treatment of Achilles tendon overuse injuries in 432 consecutive patients. The patients underwent a clinical examination 2 weeks, and 1, 2, and 5 months after the surgery. If a complication appeared, the patient was followed up clinically for at least 1 year. There were 46 (11%) complications in the 432 patients:(More)
The object was to study the relationships between calf muscle size and strength in 85 patients an average of 3.1 years after repair of achilles tendon rupture. The isokinetic calf muscle strength results were excellent or good for 73% of the patients, whereas calf muscle size was normal in only 30%. The average plantar flexion peak torque per unit muscle(More)
Ischial tuberosity pain in athletes may be caused by several clinical entities, which include acute and old bony or periosteal avulsions and apophysitis. We studied the natural course of these injuries based on our clinical case series of fourteen patients with apophysitis and twenty-one with avulsion of the ischial tuberosity. Only patients with the(More)
We determined the incidence of a total Achilles tendon rupture in the city of Oulu and changes over the 16-year period 1979-1994. During this time, 110 ruptures occurred. The incidence increased from 2 ruptures/10(5) inhabitants in 1979-1986 to 12 in 1987-1994, with a mean of 7. The peak annual incidence, 18, was recorded in 1994. The incidence was highest(More)
