Upper extremity injuries associated with strength training.

Most injuries sustained during strength training are mild strains that resolve with appropriate rest. More severe injuries include traumatic shoulder dislocations, tendon ruptures of the pectoralis major, biceps, and triceps; stress fractures of the distal clavicle, humerus, radius, and ulna; traumatic fractures of the distal radius and ulna in adolescent weightlifters; and compressive and stretch neuropathies. These more severe injuries are usually the result of improperly performing a strength training exercise. Educating athletes regarding proper strength-training techniques serves to reverse established injury patterns and to prevent these injuries in the first place. Recognizing the association of anabolic steroid use to several of the injury patterns further reinforces the need for medical specialists to counsel athletes against their use. With the increasing use of supplements such as creatine, the incidence and nature of strength-training injuries may change further. Greater emphasis on the competitive performance of younger athletes undoubtedly will generate enthusiasm for strength training at earlier ages in both sexes. The importance of proper supervision of these young athletes by knowledgeable persons will increase. As the popularity of strength training grows, there will be ample opportunity to continue to catalog the injury patterns associated with this activity.

Drugs in athletics.

Athletes are as likely as nonathletes to abuse recreational drugs. They are certainly more inclined to abuse drugs considered ergogenic aids. Accurate information is required when educating athletes regarding these drugs. Sports medicine specialists are being called on more frequently to provide this information. This article provides the basic information required to present accurate facts regarding drug abuse by athletes.

Electrical stimulation of osteogenesis.

The three electrical stimulation systems available for treating nonunion of long bones are successful in approximately 85% of cases. The percutaneous direct current bone growth stimulator is partially invasive, allows patient mobility, can be used with magnetic fixation devices, and can be monitored for proper function, but it requires an operation, cannot be used where infection exists, and is subject to breakage. The implantable direct current bone growth stimulator is similar, but is totally invasive. The external pulsing electromagnetic field bone growth stimulator is noninvasive and can be used where infection exists, but it requires long, exact patient compliance and cannot be used with magnetic fixation devices or at certain sites. None of the systems can be used where synovial pseudarthrosis or a sizeable gap between bone ends exists, nor are they more effective than bone grafting. Whether their use might evoke malignant transformation or might accelerate or retard epiphyseal growth patterns is not known. Many controlled studies are needed before it is clear how commonly electrical stimulation should be used to treat bony ununion.

Erdheim-Chester disease. A case report.

In a 57-year-old woman dizziness, staggering, altered mental status, and bilateral pain and cramping in the lower extremities developed. Extensive investigation yielded evidence of renal and long-bone lesions, with the latter being primarily metaphyseal and diaphyseal. Needle biopsy of the tibial marrow revealed the presence of lipid-laden histiocytes, osteosclerosis, and osteoclasts. A diagnosis of Erdheim-Chester disease was made; this is the 16th known case of the disease. The patient responded well to steroid therapy but later was readmitted and ultimately died of extensive infiltrates in the kidneys and pancreas. Erdheim-Chester disease, an extremely rare multisystem histiocytic disorder, has been characterized as a lipid (cholesterol) granulomatosis. Renal, cardiac, and pulmonary involvement are noted in most cases; the roentgenographic signs of skeletal involvement, when present, are pathognomonic.

Anabolic steroids: a review of the literature.

The use of anabolic steroids by athletes is controversial. On the one hand, many athletes believe that steroids improve athletic performance and thus provide an advantage to those who use them. On the other hand, the medical and scientific communities believe that inadequate scientific data exist to support the claim that anabolic steroids can improve athletic performance while overwhelming scientific data demonstrate their deleterious effects. Therefore, a large information and credibility gap concerning anabolic steroids exists between the athletes and the medical and scientific communities. We believe that this gap can be closed if both groups are better informed about anabolic steroids. We provide a detailed review of the literature on anabolic steroids that provides to the reader the information needed to make an informed decision on the relative risks and benefits of anabolic steroids to the athlete.

Prophylactic knee bracing in college football.

We report on the number of knee injuries sustained by a major college football team during 2 full years when all players were required to wear laterally placed prophylactic knee braces during all practice sessions and all games. We found that the incidence rates of knee injuries were higher when the braces were worn compared to a similar period when the braces were not worn. There was also an increased number of ACL injuries during the brace period. Several indices characterizing the nature of the injuries were analyzed and were found not to be altered significantly when the prophylactic braces were used. These facts lead us to question the efficacy of prophylactic knee braces in preventing knee injuries in college football. The use of the braces was associated with increased episodes of muscle cramping in the triceps surae muscle group, required the constant attention of coaches and trainers to remind the players to wear the braces and to apply them correctly, and was costly. These findings indicate the need for other carefully controlled clinical and biomechanical studies of these devices before their routine use can be advocated.

Anabolic steroids and growth hormone.

Athletes are generally well educated regarding substances that they may use as ergogenic aids. This includes anabolic steroids and growth hormone. Fortunately, the abuse of growth hormone is limited by its cost and the fact that anabolic steroids are simply more enticing to the athlete. There are, however, significant potential adverse effects regarding its use that can be best understood by studying known growth hormone excess, as demonstrated in the acromegalic syndrome. Many athletes are unfamiliar with this syndrome and education of the potential consequences of growth hormone excess is important in counseling athletes considering its use. While athletes contemplating the use of anabolic steroids may correctly perceive their risks for significant physiologic effects to be small if they use the steroids for brief periods of time, many of these same athletes are unaware of the potential for habituation to the use of anabolic steroids. The result may be incessant use of steroids by an athlete who previously considered only short-term use. As we see athletes taking anabolic steroids for more prolonged periods, we are likely to see more severe medical consequences. Those who eventually do discontinue the steroids are dismayed to find that the improvements made with the steroids generally disappear and they have little to show for hours or even years of intense training beyond the psychological scars inherent with steroid use. Counseling of these athletes should focus on the potential adverse psychological consequences of anabolic steroid use and the significant risk for habituation.
