摘要:

To determine whether closed metacarpal fractures (MCFs) without evidence of shortening, displacement, rotational deformity, or unacceptable angulation could be successfully treated with a modified functional casting technique (glove cast).Retrospective chart review with a follow-up telephone survey to determine long-term outcome.Outpatient sport medicine clinic.24 patients (22 male, 2 female, average age 15 ± 1.7 years) with 25 MCFs resulting from sports participation.The casting technique consisted of either a fiberglass cast (22 patients) or orthoplast splint (2 patients), allowing full range of motion of the wrist. Patients were allowed to return to modified actividy after initial evaluation and immobilization and full athletic activity upon radiographic demonstration of circumferential callus at the fracture site.Fracture healing, return to participation, complications, reinjury rates, residual symptoms, functional status, and patient satisfaction.Duration of immobilization was 4–5 weeks. All patients demonstrated radiographic evidence of union of the fracture site. All patients had returned to limited sports participation by 2 weeks and full participation by 4 weeks, with no complications, and no reinjuries occurred during the treatment period. Long-term follow-up at an average of 17.2 months showed no functional restrictions and good overall patient satisfaction.This method of immobilization demonstrates an acceptable alternative for specific, stable MCFs in athletes. Advantages include maintenance of wrist and forearm function during the period of immobilization, protection from reinjury, maximization of sports participation, and a high patient satisfaction rate.

摘要:

To assess the prevalence of use of anabolic-androgenic steroids and other presumed performance-enhancing drugs and the associated knowledge, attitudes, and behavior of school-aged Canadians.A national survey was conducted using a self-report questionnaire distributed randomly to schools within each of five Canadian regions.Canada.The subjects were 16,119 Canadian students, in the sixth grade and above, from 107 schools drawn randomly from five Canadian regions.The number of students reporting the use of anabolic-androgenic steroids and other performance-enhancing drugs in the year before the survey, the nature of such drug-taking activities, and the atitudes underlying the decision to take anabolic-androgenic steroids.More than 83,000 young Canadians (2.8% of the respondents) are estimated to have used anabolic-androgenic steroids in the year before the survey. Of those taking such drugs, 29.4% reported that they injected them; of the latter group, 29.2% reported sharing needles in the course of injecting anabolic-androgenic steroids. Significant numbers of respondents reported using other substances (caffeine, 27%; extra protein, 27%; alcohol, 8.6%; painkillers, 9%; stimulants, 3.1%; “doping methods,” 2.3%; β-blockers, 1%) in attempts to improve sport performance.The use of anabolic-androgenic steroids is more widespread than may have been assumed and is often accompanied by high-risk needle-sharing. Anabolic-androgenic steroid use is often intended to alter body build as opposed to accentuating sport performance. Many young Canadians use a variety of other substances in attempts to improve sport performance. Drug-taking of this kind represents a special challenge for educators, health professionals, and sport authorities.

摘要:

To examine the nature and incidence of injuries suffered by a sample of recreational and old-timer ice hockey players.Random sample of teams followed prospectively.Various hockey rinks in the Greater Edmonton Region.Four hundred and thirty-one subjects—287 adult male recreational (AMRL) and 144 male old-timer (OTL) from five leagues were followed over the 1992–93 hockey season.Injuries sustained during the duration of a hockey season.A total of 151 injuries (100 AMRL and 51 OTL) were reported. The aggregate injury rate was 12.2/1000 player-exposures (12.3 AMRL and 12.0 OTL). The anatomic region most often injured by AMRL players was the head/neck/facial area (32%) while OTL players reported a greater proportion of lower extremity injuries (40%). Both groups reported sprains/strains as the most common diagnosis (35% AMRL and 47% OTL). The predominant injury mechanism for AMRL players was stick contact (24%) and for OTL players was puck contact (23%). No significant differences were detected between the anatomic, diagnostic, and mechanistic distributions of injury between AMRL and OTL players. Seventy-five percent of injuries occurred during league games, 10% during playoff games, 5% during tournament games, and 10% during practices. Penalties were assessed in 31% of injury instances. Forty-two percent of head/neck/facial injuries, 32% of upper extremity injuries, 13% of torso injuries, and 15% of lower extremity occurred as a result of penalizable behavior (p = 0.01). Three percent of players wearing full or half face protectors suffered facial injuries while 9% of players not wearing facial protection reported facial injuries (p = 0.03; Relative Risk = 2.56).The injury rates observed were lower than reported rates for major/elite hockey. The proportion of players injured through body contact was lower than that observed in adult major/elite hockey while the diagnostic and anatomic distribution of injury was similar. Studies such as this are useful in the development of injury prevention strategies.

摘要:

To evaluate the long-term results in patients with patello-femoral pain syndrome after expectant management.Retrospective, case-control study.Community study in Sweden from 1981 to 1994.Forty-eight patients with patello-femoral pain syndrome were followed for a mean period of 11 years.Patello-femoral joint evaluation scale (0–100 points) was used to evaluate the functional results. Arthroscopy for evaluation of cartilage damage according to Outerbridge, and clinical assessment of knee stability and, range of motion and Q-angle.The functional results were excellent or good in 41 of 48 (85%) and poor in seven (15%). There was no correlation between the degree of cartilage damage and the level of knee function. Retropatellar cartilage damage was found in 28 patients during arthroscopy. There was no correlation between the degree of cartilage damage and the level of knee function. No patient has Outer-bridge frade IV cartilage damage. The Q-angle was 2–23°. There was no significant difference in Q-angle between patients with excellent/good results compared to those with poor.Patients with patello-femoral pain syndrome should be managed nonsurgically as the natural course is benign in most cases. Surgical intervention should be used only if correction of anatomical malalignment is necessary and if the surgical methods have proven successful in well-controlled studies with a long follow-up period.

摘要:

Compression neuropathies are common injuries about the wrist in wheelchair athletes. Thirty-three world-class wheelchair basketball players were studied electrodiagnostically to determine the prevalence and severity of median neuropathy at the wrist in these athletes.Thirty percent of these athletes had symptoms consistent with carpal tunnel syndrome (CTS), and 70% of these had electrodiagnostic confirmation of this injury. Overall, 52% of the 33 athletes had electrodiagnostic findings of median neuropathy at the wrist with nine athletes (27%) exhibiting bilateral abnormalities. Four athletes (12%) had abnormal electrodiagnostic findings involving the ulnar nerve at the wrist.This prevalence of CTS in wheelchair basketball players appears to be similar to that found in the general paraplegic population. Early recognition and treatment of CTS in these athletes are recommended to avoid chronic problems.

摘要:

To examine the hypotheses that anterior cruciate ligament (ACL) reconstruction improves the proprioception of the knee beyond the level of ACL-deficient knees, and that proprioception of the knee correlates well with knee function after ACL reconstruction.Fifty-three patients with ACL-reconstructed knees (22 men and 31 women), 30 physically active healthy volunteers with normal knees (15 men and 15 women), and 30 patients with chronic ACL-deficient knees (15 men and 15 women).A stabilometric assessment, which is considered to be a useful method for evaluating proprioception objectively, was used to compare the one-leg standing balance among three groups; and the relationship between subjective knee function, satisfaction, hop index, knee laxity, isokinetic thigh muscle strength, and one-leg standing balance in the ACL-reconstructed patients was also analyzed.The one-leg standing balance of the patients with ACL-reconstructed knees was still impaired compared with that of healthy volunteers (men, p < 0.05; women, p < 0.01), but significantly better than that of the patients with ACL-deficient knees (men, p < 0.001; women, p < 0.001). The one-leg standing balance of the patients with ACL-reconstructed knees correlated well with their functional outcomes such as subjective knee function (men, p < 0.001; women, p < 0.01), satisfaction (men, p < 0.01; women, p < 0.001), and hop index (men, p < 0.001; women, p < 0.001), whereas poor correlation was seen between functional outcomes and mechanical stability.The results suggest that knee function after ACL-reconstruction should be closely related with knee proprioception, and indicate that the usefulness of stabilometric assessment in the evaluation of the function of ACL-reconstructed knees.

摘要:

To investigate whether glenohumeral joint (GHJ) hyperlaxity is related to swimming training volume, we evaluated elite and recreational swimmers for differences in GHJ laxity and general joint hypermobility (GJH).Thirty male and female elite swimmers, aged 15–25 years, were compared with 30 recreational swimmers on five clinical GHJ laxity tests. GJH was assessed based on evaluation of hypermobility in four other joints or joint combinations.Group differences in both GHJ laxity and GJH were analyzed using X2analysis.Compared with the recreational swimmers, the elite swimmers demonstrated significantly greater GJH, as well as significantly greater GHJ laxity on three of five laxity tests. The specific patterns of greater GHJ laxity demonstrated by the elite swimmers versus the recreational swimmers favour an acquired origin for these laxity differences, while the results of the GJH assessment suggest that these laxity differences are inherent.It was concluded that a combination of acquired and inherent factors contributes to the greater GHJ laxity demonstrated in elite swimmers. We discuss the implications of this study for the prevention of shoulder overuse dysfunction (SOD) in elite swimmers.
