Grading scale of radiographic findings in the pubic bone and symphysis in athletes.

PURPOSE: Radiographic abnormalities in the pubic bone and symphysis are often seen in athletes with groin pain. The aim was to create a grading scale of such radiologic changes. MATERIAL AND METHODS: Plain radiography of the pelvic ring including the pubic bone and the symphysis was performed in 20 male athletes, age 19-35, with long-standing uni- or bilateral groin pain. We used two control groups: Control group 1: 20 healthy age-matched men who had undergone radiologic examination of the pelvis due to trauma. Control group 2: 120 adults (66 men and 54 women) in 9 age groups between 15 and 90 years of age. These examinations were also evaluated for interobserver variance. RESULTS AND CONCLUSION: The grading scale was based on the type and the amount of the different changes, which were classified as follows: No bone changes (grade 0), slight bone changes (grade 1), intermediate changes (grade 2), and advanced changes (grade 3). The grading scale is easy to interpret and an otherwise troublesome communication between the radiologist and the physician was avoided. There was a high interobserver agreement with a high kappa value (0.8707). Male athletes with long-standing groin pain had abnormal bone changes in the symphysis significantly more frequently and more severely (p>0.001) than their age-matched references. In asymptomatic individuals such abnormalities increased in frequency with age both in men and women.

Longstanding groin pain in athletes. A multidisciplinary approach.

In 21 male athletes (age 20 to 40 years) with longstanding unexplained groin pain, a multidisciplinary investigation was performed in order to reveal the underlying cause. These examinations included general surgery for detection of inguinal hernia and neuralgia, orthopaedic surgery for detection of adductor tenoperiostitis and symphysitis, urology for detection of prostatitis, radiology for performing herniography and plain film of the pelvic bones, nuclear medicine for isotope studies of the pubic bone and symphysis. In 19 patients there was a positive diagnosis for 2 or more of the diseases (10 patients had 2 diseases, 6 patients had 3 diseases, 3 patients had 4 diseases). Two patients had only signs of symphysitis. Our results show the complexity of longstanding groin pain in athletes. It also explains why therapy for one specific disease entity may fail. We conclude that this clinical setting demands the recruitment of a team with experience of different aspects of groin pain.

Alkaline phosphatase in women with osteoporosis.

Altogether 15 partially independent measurements of bone mass in 100 women with clinical and roentgenological signs of osteoporosis were correlated to the alkaline phosphatase activities of the same individuals. There was a slight but significant negative correlation indicating an increasing alkaline phosphatase activity with decreasing bone mass. This correlation was not caused by interaction of age. There was no correlation or morphological signs of osteomalacia. The changes could not be explained by fractures. It is suggested that a slight increase in the alkaline phosphatase activity in women with a more severe osteoporosis is related to bone resorption.

Bone biopsy in women with spinal osteoporosis.

Iliac crest biopsies were obtained from 110 women, 62 of whom had been clinically and radiologically classified as osteoporotics. The amount of osteoid surface was measured by a histological planimetrical method. It was demonstrated that the amount of osteoid does not differ between osteoporotic women and control women and that osteomalacia is rare in both groups.

Bone mass in primary coxarthrosis.

The bone mineral content was measured by gamma absorptiometry at two levels on the forearms, proximally on the shafts and distally close to the wrist, in 53 cases of primary coxarthrosis. The bone mineral content at the distal measuring site, representing trabecular bone, was increased in coxarthrosis cases as compared with normal controls; the difference was significant only in women. At the proximal measuring site, representing cortical bone, there was no significant difference. The findings support the concept of impairment of the resilience of the juxta-articular trabecular bone as one factor contributing to the pathogenesis of arthrosis.

Bone mineral content in the forearm after fracture of the upper limb.

The bone mineral content was measured by gamma absorptiometry in patients who had sustained fractures of the upper limb. Measurements were taken on the shafts of the forearm and in the trabecular bone immediately proximal to the wrist. Fractures of the surgical neck of the humerus and fractures of the shaft of the humerus did not significantly influence the bone mineral content of the ipsilateral forearm. Fracture of the radius and the ulna, however, caused a 15% loss of the bone mineral content in the trabecular bone proximal to the wrist, whereas the mineral content on the shafts of the fractured forearms increased or decreased depending on the fracture site. The findings suggest that measurements of bone mineral content of the forearm are not necessarily invalidated if there has been a fracture of the same limb. Only if the forearm itself is fractured should measurements on this site be avoided.

Bone mineral content and fragility fractures.

In 249 patients with fractures characteristic of bone fragility, i.e. femoral neck fracture, vertebral crush fracture, fracture of the upper end of the humerus, Colles' fracture, fracture of the lateral condyle of the tibia and various ankle fractures, and forearm bone mineral content was measured by gamma absorptiometry. Vertebral crush fracture, fracture of the upper end of the femur and fracture of the distal end of the forearm are associated with a generally decreased bone mineral mass. In young women with femoral neck fracture the difference between fracture cases and control cases was greater than in older women. In Colles' fracture, the difference from normal controls was the greatest in the youngest and the oldest women. Bone mass in the forearms is low also in cases of fracture in the upper end of the humerus, of the ankle and of the lateral tibial condyle. In each of the above groups, however, there was so much over-lap between fracture cases and control cases that the measurement of mineral in the forearm cannot be recommended as a very good tool for determination of fracture susceptability in individual subjects.

The incidence of Achilles tendon rupture.

During the years 1950-1973, 229 cases of Achilles tendon rupture were diagnosed in the city of Malmö. More than half of the injuries were caused by sporting activities, the most common being badminton and football (soccer). Ruptures caused by injuries other than sports injuries were found in considerably older subjects. During the period investigated the incidence of Achilles tendon rupture increased in the city more than could be accounted for by changes in the population. This increase could only be partly explained by the increasing interest in sporting activities in the population at risk.

Factors contributing to the production of skiing injuries.

The cause of the accident was analyzed in 981 individuals sustaining skiing injuries. Exhaustion, poor physical condition, and poor skiing technique were the most frequent causes, but poorly prepared slopes also were an important factor.

Injuries in long distance, cross country, and downhill skiing.

In 981 skiing accidents the type of injury resulting was studied in relation to the skiing activity (long distance, cross country, and downhill) and to the type of boots used. From the patterns of injuries it appears that in downhill skiing not only the velocity but also the particular type of equipment used is responsible for the increased incidence and for the characteristic types of injuries. The alpine ski boot used in downhill skiing, however, seems to protect the ankle joint and the foot from injuries that are more common in cross country and long distance skiing.

Long-term observations on the loss of bone mineral following colles' fracture.

Seventy-four women were studied at various points in time between 1 month and 12 years after a fracture of the distal end of the radius--Colles' fracture. In 50 cases the maximum loss of bone after fracture was considered to have taken place in that more than 4 months had elapsed since the accident. The bone mineral content was measured in both forearms with gamma absorptiometry. It was demonstrated that the degree of post-traumatic osteoporosis, calculated as the difference between the values obtained for the injured and the uninjured arms, decreased with time. The difference between the arms was greater in peri- and early postmenopausal and in very old women suggesting that these groups had lost more bone and/or been less able to restore lost mineral with time.
