Heterotopic bone formation in abdominal midline scars.

The heterotopic bone formation may occur in vertical upper abdominal midline scars. Fifteen such patients are reported. They all had annoying pressure symptoms and seven of them were operated due to the symptoms. The excised bone formation was located between the fascia and peritoneum fixed to the fascia. The ossification of the upper midline abdominal scar seems to be ten times more common in men than in women. The bone formation of the scar may cause problems in differential diagnosis, especially in the early phase of calcification. The radiological diagnosis is usually easy, either by plain roentgenography or if oblique views of the abdomen are taken.

Blunt injury of the radial and ulnar arteries in volley ball players. A report of three cases of the antebrachial-palmar hammer syndrome.

Three cases of the antebrachial-palmar hammer syndrome are described in volley ball players. They all suffered from a decreased blood perfusion of their right hand and fingers due to the repeated ball and floor impacts during the volley ball training and playing. The vascular lesions of the radial and ulnar arteries were reversible. The patients recovered spontaneously during the rest from excessive physical activity by their hands. The vascular lesions of this kind are rare but seem to be typical to volley ball players.

Radiographic instability of the ankle joint after Evans' repair.

Forty-two unstable ankle joints were treated surgically by Evans' operation. The clinical postoperative results were correlated with the objective radiological stress examinations. The mean age of the patients was 29 years (15-60 years). The clinical and radiological follow-up examinations were performed 6 months after the operation. In the stress X-ray examinations a modified stress frame was used. Clinical instability was noted in four patients. In the radiological examination one patient had a pathological finding in the talar tilt test and 18 patients in the anterior drawer sign test. The radiological instability correlated poorly with the subjective end results. Six patients were estimated to have a poor result of the operation. Five of these patients had a positive anterior drawer sign in the stress X-ray examination and one had degenerative changes in the ankle. Although Evans' repair is a simple and reliable method of reconstructing ruptures of the lateral ligaments of the ankle joint, it is associated with a relatively high frequency of positive anterior subluxation on radiological stress examination. This finding can be explained by the anatomical and geometrical factors on the lateral side of the ankle joint.

Osteochondroses in athletes.

Osteochondroses are disorders of primary and secondary growth centres, or lesions at the apophyseal or epiphyseal growth areas of bones. Although there are many types of osteochondroses, the history, clinical symptoms and findings as well as radiological findings are typical. Physical exercise is one of the factors that provokes symptoms. In a series of 185 osteochondroses in active young athletes, there were 18 different disorders. The commonest were Osgood-Schlatter's disease, Sever's disease, osteochondritis dissecans of the femoral condyles, various other patellar osteochondroses and Scheuermann's disease. Most of the athletes were from individual events; track and field sports (53.5%), cross-country skiing (8.1%), gymnastics (3.2%) and power events (2.7%). Of the team sports soccer produced the most (20.0%). The treatment was conservative in 84.3% and operative in 15.7%. The duration of symptoms in these athletes persisted in about 43% for less than one year and in 57% for more. The late changes of osteodhondroses do not cause serious risks for a normal life, if the treatment is active and the follow-up efficient.

Stress fractures in young athletes.

In a series of 16 cases of stress fractures in 15-year-old and younger athletes 8 fractures occurred in boys and 8 in girls. There were no differences between the sexes in the athletes' training habits. Ten of the fractures were located at the tibia, seven at its upper third and three at the lower part of the bone. Three fractures were found in the fibula, in the metatarsal bones two stress fractures and in the femur one stress fracture. Most stress fractures were caused by endurance type sports. The daily training distances were not particularly high at the time of the onset of the symptoms. In most cases the diagnosis was based on a radiological evaluation. A sufficiently long pause from all athletic activity was enough treatment. Stress fractures in children are very uncommon.

Exertion injuries in female athletes.

Because sports injuries in men form most of the available statistics, the reportage of injuries in female athletes is sparse. We describe exertion injuries and disorders in 281 women athletes, all of which hampered athletic training or performances. Sixty per cent of the injuries occurred to girls ages between 12-19 years, and about forty-eight per cent were track and field athletes. The most common sites of injury were the ankle, foot, heel and leg. Osteochondritic disorders were the most typical injuries in the series, and the chronic medical tibial syndrome was the injury that needed surgical treatment most frequently. Overuse injuries seem to differ very little from each other in the events included in this survey.

Comparison of dextranomer and streptokinase-streptodornase in the treatment of venous leg ulcers and other infected wounds.

The clinical efficacy of dextranomer (Debrisan) and streptokinase-streptodornase (Varidase) was compared in a controlled randomized in-patient study. There were two patient groups: Group A consisting of 28 patients with a total of 31 venous leg ulcers and Group B consisting of 56 patients with other infected wounds (posttraumatic and postoperative wounds, amputation stumps, burn wounds, arteriosclerotic ulcers, decubital ulcers, ulcers due to bone disease, rheumatic ulcers, ulcers due to erysipelas and wounds of mixed aetiology). Both agents have a good cleansing effect as well as a good effect on infection and wet necrosis. Dextranomer stimulates the formation of granulation tissue faster than streptokinase-streptodornase.

Heterotopic ossification in upper midline abdominal scars.

Heterotopic ossificaton of the upper midline abdominal incision scar is reported in seven patients. This disorder may follow abdominal operations via vertical incisions. The cause is unknown. All patients were men in their fifties. The calcification resembled a "rib" and occurred in upper midline incisions between the peritoneum and fascia, fixed more to the fascia. Excision of the mass was performed in six cases. Excision is recommended only in symptomatic cases, and should be wide enough to avoid recurrence. In the differential diagnosis several other wound complications as well as intra-abdominal malignancy should be considered.

Athletes' leg pains.

The frequency and nature of exertion pains of the leg in athletes were studied in 2,750 cases of overuse injuries treated at the Sports Clinic of the Deaconess Institute of Oulu, Finland, during the years 1972-1977. 465 cases of exertion pain (18%) were located in the shin. The medial tibial syndrome was the most common overuse injury among these athletes, comprising 9.5% of all exertion injuries and 60% of the leg exertion pains. Together with stress fracture of the tibia, the second most common exertion pain of the leg, it accounted for 75% of the total leg pains. There are certain difficulties in differentiating between the medial tibial syndrome and stress fracture of the tibia. They both occur at the same site with similar symptoms. Radiological examination and isotope scanning are needed. The medial tibial syndrome is an overuse injury at the medial tibial border caused by running exercises. The pain is elicited by exertional ischaemia. The pathogenesis is explained by increased pressure in the fascial compartment of the deep flexor muscles due to prolonged exercise. Similar chronic ischaemic pains from exercise are also found in other fascial compartments of the leg, especially in the anterior compartment. The only treatment needed for stress fractures is rest from training. Fascial compartment pains also usually subside. If chronic fascial syndromes prevent training, fasciotomy is recommended as a reliable method to restore the athlete to normal training without pains.

[Osteochondritis dissecans of the patella (author's transl)].

Five cases of osteochondritis dissecans patellae were seen and followed during years 1971--1978. Special interest was pointed to the site of the lesion, at which age the disease appeared, and to the physical activity of the patients. In one case only patellar subluxation could be confirmed. In two cases radioisotope (Tc99) szintigraphy was done with positive finding. The radiological finding was typical in all cases. The treatment was conservative in all cases but one. Loose body formed once in the series. Operative treatment should be directed only to the cases with persistent symptoms and/or loose bodies.

Exertion injuries in adolescent athletes.

A series of 147 cases of exertion injuries in less than or equal to 15 years old athletes is presented. All injuries occurred during training or athletic performances without trauma and caused symptoms that prevented athletic exercises. There were 67 girls (46%) and 80 boys (54%) in the material. About 90% of them had been training for more than one year before the onset of the symptoms; 65% were interested in track and field athletics, 13% in ball games, 11% in skiing, 4% in swimming, and 3% in orienteering. The rest were interested in other sports. About 33% of the injuries were growth disturbances or osteochondroses seen also in other children. About 15% were anomalies, deformities or earlier osteochondritic changes, which caused first symptoms during the physical exercise; 50% were typical overuse injuries that may bother adult athletes, too; 43% of the injuries were localized in ankle, foot and heel, 31% in knee, 8% in back and trunk, 7% in pelvic and hip region, and the rest in other parts of the body. The injuries were generally slight, no permanent disability was noticed. Rest and conservation therapy cured most cases; operative treatment was used in only eight cases.

Iliotibial tract friction syndrome in athletes--an uncommon exertion syndrome on the lateral side of the knee.

An uncommon exertion pain on the lateral side of the knee is described in 88 patients, in four of whom it was bilateral. The disorder is a result of the friction of the iliotibial tract over the lateral femoral epicondyle. The syndrome is the iliotibial tract friction syndrome of ITFS. All the patients in the material were active athletes or middle-aged joggers in regular training. The cases were seen over four years and four months. The mean age of them was approximately 25 years, and there were only nine women in the series. Th pain appeared usually after running and was localised on the outer femoral condyle, and often radiated downwards along the iliotibial tract. Conservative treatment and changes in training habits cured most cases. The disorder has not often been described in the literature, and seems to appear only in physically very active people, such as athletes or military recruits.

Stress fractures caused by physical exercise.

A series of 142 stress fractures caused by sporting activities and physical exercise is presented. 121 fractures occurred in athletes and 21 in non-competitive sportsmen. Distance runners presented with 68 fractures, skiers 12, sprinters 10, orienteering runners 9, vaulters 3, and football-players 3 fractures. Athletes engaged in other events had fewer stress fractures. 76 fractures occurred in the tibia, 26 in the metatarsal bones, 20 in the fibula, 5 in the femoral neck, 4 in the femoral shaft, and 2 in the metacapal bones, lower pubic arch and sesamoid bones of the first MTP-joint. There was one fracture of each of the following: the humeral shaft, the ulna, the vertebral arch of L 5, the tarsal navicular and the proximal phalanx of the fifth toe. The treatment was generally a pause in training for 4-6 weeks, on the average. Running caused most of the stress fractures; the rest followed jumping exercises. The athletes mostly developed stress fractures during a period of alteration from one training session to another or during the preparation period close to the competition season. Joggers usually developped stress fractures 2-4 months after the beginning of regular training.
