Traumatic rupture of the extensor tendons at the musculotendinous junction.

Ten cases of closed extensor tendon rupture at the musculotendinous junction are reported. In five patients the rupture occurred at work, and in five during athletic activities. In each instance, indirect tendon injury resulted from a strong stretching force applied to a contracting muscle. In one case, rupture of the extensor pollicis longus tendon occurred proximal to the extensor retinaculum. In eight cases of complete tendon rupture direct repair was impossible. Of these eight patients, five were treated by side-to-side juncture and three by tendon transfer. Two patients with incomplete rupture were treated by splinting. All patients improved after treatment.

The effect of calisthenic home exercises on postmenopausal fractures--a long-term observational study.

OBJECTIVES: To evaluate the long-term effects of calisthenic home exercises on the incidence of fractures in postmenopausal women. DESIGN: Controlled long-term observational study. METHODS: Postmenopausal women between 45 and 75 years of age who had been randomly assigned to an exercise or control group in the course of a previous study conducted 5-10 years ago, were invited for follow-up. The number of fractures before and during the observation time were recorded by means of a questionnaire. Vertebral deformities due to fractures were diagnosed by X-rays at entry and at follow-up. Walking speed, muscle strength, static posturography, and maximum oxygen uptake were measured in addition. RESULTS: After an average follow-up time of 7.6+/-1.1 years, 73 women of the exercise group and 64 subjects of the control group were investigated. Thirty-three per cent (n=24) of the exercise group reported to have exercised continuously at least three times a week for 20 min. No intergroup differences between the compliant and non-compliant exercisers and the control group were seen in the number of fractures. However, the incidence of fracture was lowest in women with a baseline bone mass less than one standard deviation (SD) below the mean for young adults (high BMC) and highest in those with more than 2.5 SD below the mean for young adults (low BMC) (P<0.001, odds ratio 2.9 [95% CI, 1.59-5.39]). CONCLUSION: This long-term follow-up did not produce any evidence that prescription of a calisthenic home exercise program may prevent fractures in postmenopausal women aged between 61+/-6.4 and 68+/-6.5 years.

Failure of heat shrinkage for treatment of a posterior cruciate ligament tear.

Incomplete tears or traumatic elongations of either the native cruciate ligaments or cruciate ligament reconstructions represent a therapeutic dilemma for orthopaedic surgeons. We report a case of a partially torn posterior cruciate ligament that was treated unsuccessfully with an electrothermal shrinkage procedure. Although the use of thermal energy to selectively shrink tissues may ultimately prove to be an invaluable tool, the lack of well-designed, randomized controlled studies to firmly establish its efficacy in the treatment of partial cruciate injuries mandates cautious use of this technique at this time.

Sex-linked differences in equilibrium reactions among adolescents performing complex sensorimotor tasks.

Equilibrium reactions were compared between male and female adolescents (prepuberal and puberal), classified into two groups: those who had previously learned complex motor tasks (dance or acrobatics) and those with no particular training. Subjects stood (eyes open or eyes closed) on a free seesaw platform, the displacements of which were calculated from accelerometer measures. They were instructed to maintain a vertical position with their frontal plane either parallel (to measure antero-posterior oscillations) or perpendicular to the axis of the platform (to measure lateral oscillations). Girls had a better stability than boys as shown by the smaller displacement of their center of gravity. Untrained subjects, irrespective of sex, were the least stable. Subjects trained in acrobatics were more stable than dancers. Differences related to sex can be attenuated by physical training involving equilibrium exercises which suggests that moderate sustained training could reduce the incidence of falls in aged persons and in professionally exposed workers.

How do somersaulters land on their feet?

Body movements of trampolinists landing upright from forward somersaults, with eyes open and closed, were analyzed to test a theory of how braking and timing of actions are conjointly controlled. In regulating landing, rotation has to be slowed by extending the body so that it reaches the upright just as the feet hit the trampoline. Extending a theory of visual control of linear braking, it was hypothesized that upright landing is achieved by perceptually regulating body extension so as to keep the ratio angle of body to upright: rate of change of angle (the tau function of the angle) proportional to time-to-landing. The data support the hypothesis, indicate that vision improves precision of control, and argue further for the value of the tau function in the perceptual regulation of action.

[The influence of permanent cerebellar stimulation on senso-motor disorders in cerebral palsy (author's transl)].

Based on Cooper's good results implantation of a bilateral cerebellar stimulator was performed in 2 children with cerebral palsy. The patients suffered from marked hypertonia of all limbs and involuntary movements. The follow-up study of 8 months revealed a decrease of spasticity and a progressive improvement of fine motor control. Our preliminary results justify the clinical application of cerebellar stimulation for functional treatment of sensory-motor disorders.

Adolescent ACL injury: treatment considerations.

Anterior cruciate ligament (ACL) injury in a skeletally immature patient presents unique treatment challenges. In many cases, conservative treatment with bracing and physical therapy fails, resulting in recurrent instability, pain, swelling, and meniscal and chondral injury. The goal of surgical reconstruction is to recreate ACL stability without causing growth plate arrest, leg-length discrepancy, or angular deformity. Patient characteristics such as skeletal age, Tanner stage, onset of menses, family member height, growth spurt, recent change in foot size, and growth charts can help the surgeon approximate the degree of skeletal maturity and aid in selecting the timing and safest type of reconstruction. Numerous surgical techniques, ranging from an extra-articular reconstruction to intra-articular graft passage without physeal violation to standard transtibial and transfemoral tunnel placement with physeal violation, have been popularized. The majority of existing studies are retrospective case series, describing a particular author's specific technique experience. This article reviews the basic science and clinical literature, presents a treatment algorithm, and provides several case studies.

Correlations between aerobic capacity, pulmonary and cognitive functioning in the older women.

Regular aerobic exercise improves aerobic capacity and increases brain blood flow and oxygenation. Exercise also stimulates the reticular activating system and leads to a centrally excited state thereby makes the brain active and alert. In the present study, an aerobic exercise program consisting of submaximal level calisthenic exercises was devised for relatively healthy women between 60 and 80 years old, attending a solidarity center for the aged for daily activities. The effects of exercise on aerobic fitness, and the correlations between aerobic capacities, pulmonary functions and cognition were evaluated. Following a general health examination, 45 female volunteers fulfilling the international criteria of exercising standards for the aged were included in the program. The rhythmic and entertaining calisthenic exercises were performed by the older women for four months, three days a week, 40 or 50 minutes a day. Tests for aerobic capacities, pulmonary functions, and some neuropsychologic performances were carried out during the sedentary period and after the exercise program. The results revealed significant improvements in aerobic capacity, pulmonary functions, and some of the cognitive functions after the 4-month exercise program. We found strong relationships between aerobic capacities and cognitive functioning. Overall, the subjects expressed their happiness and well being on every occasion, during and after the exercise program.

Indications of prevalence, practice and effects of anabolic steroid use in Great Britain.

A growing number of reports of anabolic-androgenic streroid (AS) use in Great Britain (GB) among non-competitive groups have emerged since the beginning of 1990s. A study was commissioned by the Departments of Health for England, Scotland and Wales, to explore the extent and uses of AS from the public health point of view. As a part of a wider investigation into AS use, 21 gymnasia in England, Scotland and Wales were surveyed by questionnaire. The response rate was 59%. We found that of the 1667 participants, 9.1% of the men and 2.3% of the women had taken AS at some time and 6% of the men and 1.4% of the women were current users. Considerable variation in the prevalence of use was found, ranging from no reports in three of the gymnasia, up to 46%. We also investigated patterns of AS use and perceived side-effects in a wide-ranging group of AS users (n = 110), who were recruited through social networks. In-depth interviews with the users revealed that the 97 men (27+/-7 years) and 13 women (25+/-5 years) had been using AS regularly for 2.05+/-1.7 years and 1.9+/-2 years, respectively. Seventy-two injected AS. While most injected themselves, 25% were mainly injected by their friend. Up to 16 different drugs were taken by interviewees during the present or last cycle. Polydrug use was common and dosage taken exceeded therapeutic recommendations. Sixteen interviewees did not report side-effects, while the majority reported two or more. Many of these were cosmetic. Of the 97 men interviewed, 56% reported testicular atrophy, 52% gynaecomastia, 36% elevated blood pressure, 56% fluid retention, 26% injuries to tendons, 22% nosebleeds and 16% more frequent colds. Six men reported problems with kidney function and five with liver function. Problems with sleep were reported by 37%. Of the 13 women interviewed, eight reported menstrual irregularities, eight fluid retention, four clitoral enlargement, three decreased breast size and two elevated blood pressure. Four reported sleeplessness.

[Traumatology and sports injuries in equestrian acrobatics in the adolescent].

The objective of this study was to compile knowledge of athletic injuries and complaint patterns related specifically to equestrian acrobatics (e.a.). A 20-page standardized questionnaire was sent to 114 e.a. participants. The mean age of the participants in e.a. groups was 15 +/- 3 years, that of independent participants 21 +/- 3 years. A total of 489 injuries was reported, mainly to muscles and tendons (35%), skin (33%) and joints and ligaments (25%). Bone injuries (6%) and head injuries (2%) were infrequent. Analysis of the localization showed that the head-face-neck region was involved in the injury in 3.9%, the torso in 5.5%, the upper extremities in 28%, pelvis and hip region in 3.9%, and the lower extremities in 52%. More than half the injuries were categorized in severity grade I (55%) (not requiring medical attention), 25% were grade II (single medical treatment), 15% grade III (several outpatient medical treatments) and 5% grade IV (requiring hospitalization). Nearly half of the injuries to the lower extremities resulted from jumping exercises, while the cause in upper-extremity injuries was mostly falling (37%). The importance of fall training and limitation of difficulty as well as the number and height of the jumps is discussed. Regular medical examination and improved education of the trainers are demanded.
