[Acute and chronic overuse injuries in extreme sport-climbing].

From May to September 1994 a study on acute and chronic overuse injuries in to rockclimbing was performed. The etiology of trauma was referred to trainingforms and climbing techniques. 112 climbers participating in the study climbed at level 9+/10- (8a). This study demonstrated that the incidence of overstrain syndromes increased with the performance level. The overall predominance of finger injuries was followed by acute spinal syndromes, knee, and ankle sprains. Among the most frequent overstrain complaints epicondylopathias, chronic complaints of the finger joins and flexor tendons, and nerve compression syndromes of the upper extremities could be seen. Most notable was the fact that the frequency of certain overstrain syndromes increased in relation to the years of climbing.

[Injury risk of competitive, handicapped cross-country skiers in training nd competition].

Injuries caused by cross country skiing have been poorly investigated in handicapped athletes. The dynamic sliding shape of motion makes this sport to a suitable discipline for people with a deficit of locomotion. Visual handicapped people with a guide are able to improve their motoric skills, co-ordination, orientation and body self-consciousness in the track. Since handicapped athletes are performing in international competitions the training intensity to fulfill the requirements, but also the risk of overstrain induced injuries got increased, like in other high-performance sports. Our study examined injuries and overuse syndromes of the German National Team Ski Nordic during the Paralympics in Tignes/ Albertville (1992). Lillehammer (1994) and the training period in preparation for the Paralympics in Nagano (March 1998). The incidence and kind of injuries in the competitive handicapped cross country skier was comparable with non-handicapped athletes, but the injury pattern was different.

[Wheelchair basketball from the orthopedic viewpoint].

155 (aged 16 to 52 years) wheelchair basketball players were surveyed to determine athletic injuries and overload-syndromes. During their active participation in wheelchair basketball 60.6% of the players have suffered 272 injuries and overload-syndromes. Those were mainly localised at the upper extremity (74.6%). Acute injuries predominate with 57.7%. Strains of the finger joint and skin injuries were found to be the most common injuries. Myogelosis and tendinosis were the most common reported overload-syndromes. A significantly higher number of complaints were associated with wheelchair basketball participation at league-level and depending on the player's position. At the end of the article the means of possible additional disability and consequences to specify therapy and prevention for disabled will be discussed.

[Risk of injuries, symptoms of excessive strain and preventive possibilities in cross-country skiing. A comparison between classical technique and skating technique].

A standardised questionnaire was drawn up and submitted to 690 cross-country skiers active in popular (pastime) sports, competitive sports and high-performance sports, between 1990 and 1993, covering a total of 189 injuries and 1,281 cases of complaints caused by overstrain. Over and above this, muscular imbalance and postural characteristics (for example, signs of vestibular syndrome) were examined in 94 of these skiers. Three times as many skiers (69.3%) reported on complaints than skiers reporting on injuries (20.3%). Complaints concerned particularly the lower extremities (45.9%), whereas injuries were more frequent at the upper extremities (47.6%). Minor injuries predominated (77%) such as sprains and distortions (23.8%), contusions (25.9%), skin injuries (13.7%) and muscle injuries (13.7%) as well as mild complaints (45.1%) such as blisters at the hand and feet. High-performance sportsmen (14.4%) are significantly most frequently injured when employing the skating technique, whereas in competitive sports the "classical" technique results in a greater incidence of accidents (16.1%). Most accidents occur during downhill skiing, on rutty and icy tracks, collisions, due to inadequate technique, lack of balance and unskilled handling. Complaints are significantly reported by competitive (70.8%) and high-performance sports people (74.8%) for both techniques. Whereas complaints at the lower extremities occur more often during skating technique (56.8%) than during the classical technique (34.5%), complaints concerning the trunk are seen more often with the classical technique (29.7%) than with the skating technique (8.9%). Complaints are caused by icy, rutty tracks, inadequate equipment, deficient training, muscular imbalances and previous damage. A large number of pointers on how to avoid pitfalls when employing the skating and classical techniques can be obtained via analysis of the injuries and complaints.

[Chronic shoulder pain in the volleyball attack player].

30 competitive volleyball attackers of the German third league, 15 with shoulder pain (group I) and 15 without shoulder pain (group II) were examined clinically and sonographically. Anamnesis was also carried out. The results were compared with those of a control of 15 non-volleyball players not subject to stress caused by overhead use of their arms. On the visual analog scale the average pain was 5.1 (SD 1.4). The average history of pain was 2.7 (SD 2.7) years. Cause for the pain was "spiking without warming up" (n = 7) or "unknown" (n = 8). Spiking respectively serving caused new pain sensation in 14 (11) attackers. Players of group I stretched shorter than those of group II. Pain was located laterally to the greater tuberculum (n = 8), at the origin of the deltoid muscle (n = 3), at the bicipital groove (n = 2) or in the area of the ventral glenoid (n = 2). Pain was caused by active anteversion above 160 degrees (n = 3), active abduction above 140 degrees (n = 2) or both (n = 10). The playing shoulder was depressed in all 30 volleyball attackers. By measuring the distance from the epicondylus radii to the acromion of the other side by maximal forced horizontal adduction, the distance from the margo medialis scapula to the spine, the distance from the tip of middle finger to the lumbar spine by maximal internal rotation of the shoulder up the back showed significant differences between both sides and between the groups. The spiking arm scapula is significantly lateralised compared to the opposite side and compared to sportsmen.(ABSTRACT TRUNCATED AT 250 WORDS)

[Stress-related clinical and ultrasound changes in shoulder joints of handball players].

This prospective clinical and ultrasound study was performed to show specific overuse injuries or changes in the periarticular structures of shoulder joints. Therefore, 11 male handball players with an average age of 23 years and 6 months were evaluated via a standardised shoulder exam sheet and an ultrasound examination before, one hour after, 10-12 hours after, 16-20 hours after and 22-24 hours after specific handball training. Characteristic changes were found in respect of bursitis subacromialis and tendinitis of biceps tendon up to 16-20 hours after training, which were fully reversible 22-24 hours after the stress. The effusion was visible for more than 24 hours after the training but was reversible 60 hours after stress. This study shows characteristic pariarticular changes in the shoulder joint of handball players without any clinical finding in physical examination, so that the ultrasound changes seem to be a physiological reaction to the specific stress. These changes should therefore not be misinterpreted especially if there are no clinical symptoms.

[Overuse syndrome in ballet: study of the effect of a tape bandage of the upper ankle joint with motion analysis].

In six ballet dancers with overuse syndromes of the foot a study on the effect of taping on stabilisation, proprioception and muscular activity was performed. By using synchronous surface electromyography and 3-dimensional motion analysis three standard ballet positions without and with applied tape were performed. Muscular activities of pronator muscles (peroneus longus) and supinator muscles (tibialis posterior) were recorded. EMG measurements showed significant differences between patients with stable or unstable ankles and painful or pain-free feet. Applying tape led to significant changes of muscle activities in height and antagonist reflex patterns. These changes were highest in dancers with unstable ankle joints and metatarsalgia.

[Surgical treatment of soccer player's ankle joint].

In experienced football players spurring and calcifications of the ankle joint's capsule attachments may be found more often than in other sportsmen. Basing on functional and sometimes already established ankle joint instability pain may develop. Out of 374 football players throughout 1989-1992 with injuries to the ankle joint 49 were operated on. These showed chronical instability and radiologically visible alterations in accordance with the imaging of footballer's ankle joint. 40 of these patients could be followed up. 16 exact fibular ligament repairs and 19 reconstructions were performed, 15 tibioventral, 6 talodorsal, 12 fibular and three medial capsule calcifications and spurs were excised, 8 loose bodies removed, three cases of osteochondritis dissecans drilled. After an average follow up of 25.6 months we saw stable ankle joints in all patients with resting local pain in 15 patients, among them 7 load dependent and 6 with slight limitation of dorsiflexion. Sport activity level showed 25 patients improved, 11 equal, one worse and three with changed disciplines.

[Jogging--stress-induced damage of the musculoskeletal system].

During a period of 8 months 121 male and 99 female joggers were interviewed by a standardised questionnaire in respect of their running behaviour and problems caused by jogging. Only such runners were included who had jogged regularly on at least 2 days, regarding women on at least one day per week for at least 30 minutes during the last 2 years. Additionally a detailed orthopaedic examination was carried out in the ambulance of the Orthopaedic University clinic. The overwhelming majority of male and female joggers had a secondary education and practised easy physical activities. Only 4 per cent of the interviewed persons worked physically hard. In connection with jogging, 67 male and 44 female joggers developed signs at the locomotor system. Among the major problems with regard to running were Achilles tendinitis, calf muscle strain, shin splints and complaints referring to foot deformities. Injuries were seen only rarely. Jogging on forest grounds and cinder paths is less strenuous compared to asphalt tracks or tartan paths. Training errors were among the main causes of complaints occurring during running. Traumatic or posttraumatic influences as well as incorrect footwear were of secondary importance regarding the occurrence of complaints.

[Complex movement analysis: dynamic study of the effect of a tape bandage on pronation in high-jumping with three-dimensional movement analysis and electromyography].

Overuse syndromes in the lower extremity are a frequent problem in athletics, especially in jumping events. Athletes notice a comfortable support by using ankle taping without restriction of their performance. Up to now no objective data is available about efficiency of taping against overpronation which is frequent in high jumping. In high jumping without boots little difference of pronation between taped and untaped take off leg was found. In contrast in jumping with spikes boots a marked pronation during take off was found, which was reduced by ankle taping with a reduction of maximum medial malleolar medialisation by 77%, reduction of pronation time by 33% and time of maximum pronation by 8.2% in the take off leg. Surface electromyography showed an increased activity of M. peroneus longus by 30.7% as a plantarflector and pronator muscle with ankle taping. Activity of other jump supporting muscles of the lower extremity was little influenced.

[Changes in the skeleton of the middle foot caused by professional classical dancing].

UNLABELLED: On half and three-quarter points, the most frequent foot positions in dance, the metatarsals form an extension of the lower leg. In 54% of 56 professional male and female dancers whose feet were examined, this extraordinary stress leads to pronounced thickening of the cortex of the second metatarsal and in 6%, of the third metatarsal as well. There are no symptoms. Hypertrophy of the bone occurs in response to the additional stress imposed by dancing. Dancing on points is not the triggering factor, since male and female dancers are equally affected. COMPLICATIONS: Under intensive stress of dancing, pain can develop in the medial portion of Lisfrans joint and endanger the dancer's career. Skeletal scintigraphy in such cases reveals increased metabolism of the bone at the base of the second metatarsal as well as in the cuneiforme intermedium. The development of this overstress on the second ray is favored by the following factors: Primarily by the congenital pes cavus which makes correct stressing of the foot in dancing impossible; a relatively long second metatarsal, or possibly the third metatarsal as well; - by an excessively large antetorsion angle of the neck of the femur, which makes correct positioning of the foot in the five positions of classical dance impossible; - by overstressing the half-points position in teaching, or by unfavorable training conditions, especially floors that are too hard. No treatment of these painful complications is possible if they are caused by anatomical factors. In other cases, several month's rest, changing ballet technique, and improved conditions regarding the ballet floor can result in an improvement. Even then, relapses are not infrequent, however.

[Injuries and damage caused by excess stress in body building and power lifting].

A questionnaire, designed to elict information about training programs, experience and injury profile, was administered to 358 bodybuilders and 60 powerlifters. This was followed by a clinical orthopedic and radiological examination. The upper extremity, particulary the shoulder and elbow joint, showed the highest injury rate. More than 40% of all injuries occurred in this area. The low back region and the knee were other sites of elevated injury occurrences. Muscular injuries (muscle pulls, tendonitis, sprains) were perceived to account for 83.6% of all injury types. Powerlifting showed a twice as high injury rate as bodybuilding, probably of grounds of a more uniform training program. Weight-training should be associated with a sports-related medical care and supervised by knowledgeable people, who can instruct the athletes in proper lifting techniques and protect them from injury which can result from incorrect weight-training.

[Triathlon--continuous stress on muscles, tendons and bones?].

Injuries in triathletes are in the majority of the cases exertion injuries; trauma is rare. An athlete developed in triathlon races, after two metatarsal stress fractures and one in the distal tibia, a fourth stress fracture in the proximal tibia. The injury-provoking factors were a steep increase of the weekly mileage in combination with a pronated flat foot.

[Excessive stress damage of the lower extremity caused by sports. The value of sonographic diagnosis in stress damage of the lower extremity].

150 sportsmen with lesions and diseases of the lower extremity served as basis for demonstrating the possibilities offered by diagnosis via sonography. Main indications were articular and paraarticular diseases of the large joints (hip and knee) to demonstrate effusions, ganglia, bursae and tendon ruptures, diseases and injuries of the musculature at the thigh and lower leg, as well as the Achilles tendon with its various changes such as rupture, achillodynia and peritendinitis. Muscular and tendon ruptures can be differentiated via sonography in respect of extension, type, age and localisation. This makes differentiated treatment possible. Intraarticular lesions of the knee joint remain the domain of arthroscopy. Sonographic findings should always be supplemented by anamnesis, clinical findings and x-ray film so as not to overlook any bony injuries and damage of the capsular ligaments.

[Does excessive stress play a role in the development of osteochondrosis dissecans tali?].

At the follow-up examination of 61 patients with Osteochondrosis dissecans tali (OD) we found at 48 of them one or more injuries in the anamnesia. More than 70 percent of them had as an injury mechanism a supination trauma. In case of medial OD the possible cause of an OD is given by the ratio 34 to 12 of trauma and non-trauma. The ratio in case of a lateral OD is 14 to 1 and it almost definitely points to overstress being a cause of it. Primary reasons may be here sports, especially football.
