    ABSTRACT: The treatment of glenohumeral joint instability plays an important role in sports medicine. The instability of the shoulder includes various degrees of severity from symptomatic hyperlaxity, to subluxation, to dislocations. In this article, specific aspects of adequate patient selection are discussed with regard to treatment options. Certainly, the different available classifications do not describe all forms of instability as also mixed forms occur frequently. Nevertheless, they provide a vital guide and assistance during the treatment finding process. Furthermore, different treatment options are discussed and the indications and limitations of surgical treatment highlighted.

    ABSTRACT: In a retrospective questionnaire analysis 360 canoeists were asked about their sport-related complaints and injuries within the last four years. Finally 104 elite-canoeing-athletes could be included. The allocation of the injuries and overuse symptoms was carried out by body region. Shoulder problems have been reported with a frequency of 26%. Pain in the lumbar spine and the knee joint was reported in 33% and 27% of the athletes. Dysesthesia in the legs (32%) and wrist-pain (29%) were also reported in about one third of the athletes. The present paper shows that canoeing as obvious upperbody stressing sports can also lead to complaints like dysesthesia of the legs and pain in the lumbar spine, knee and wrist. These complaints occur almost as often as the expected shoulder complaints.

    ABSTRACT: Nach Knietraumen und operativer Versorgung sind die Voraussetzungen zur korrekten Propriozeption gegeben. Der peripher-afferente Schenkel, die spinale und zentrale Reizverarbeitung sowie der peripher-efferente Schenkel sind nach Kniebinnentraumen und -operationen intakt. Veränderte peripher-sensorische Wahrnehmungen (Afferenzen) sind durch das Knietrauma bedingt. Es kommt zu einer Reduktion des absoluten Krafteinsatzes und der aktiven Beweglichkeit, zu einer Veränderung der Muskelselektion sowie zu Verlängerungen neuromuskulärer Reaktionszeiten. Postoperative Übungen müssen es dem Patienten ermöglichen, alltagsnahe positive sensorische Erfahrungen zu sammeln. Despite some alterations of receptor thresholds after knee trauma and surgical treatment joint receptors provide the prerequisites for correct proprioception. The peripheral afferent pathway, the spinal and central stimulus processing and the peripheral efferent pathway are intact. Alterated peripheral sensory perception is caused by the knee trauma induced change of proprioception. A reduction of absolute torque, active range of movement, modified muscle selection and delay in neuromuscular latency time are observed. Postoperative exercise should enable the patient to gather positive sensory experience enclose to activities of daily living.

    ABSTRACT: Mild cognitive impairment, especially executive dysfunction might occur early in the course of Parkinson's disease. Cognitive training is thought to improve cognitive performance. However, transfer of improvements achieved in paper and pencil tests into daily life has been difficult. The aim of the current study was to investigate whether a multimodal cognitive rehabilitation programme including physical exercises might be more successful than cognitive training programmes without motor training. 240 PD-patients were included in the study and randomly allocated to three treatment arms, group A cognitive training, group B cognitive training and transfer training and group C cognitive training, transfer training and psychomotor and endurance training. The primary outcome measure was the ADAS-Cog. The secondary outcome measure was the SCOPA-Cog. Training was conducted for 4 weeks on a rehabilitation unit, followed by 6 months training at home. Caregivers received an education programme. The combination of cognitive training using paper and pencil and the computer, transfer training and physical training seems to have the greatest effect on cognitive function. Thus, patients of group C showed the greatest improvement on the ADAS-Cog and SCOPA-COG and were more likely to continue with the training programme after the study.

    ABSTRACT: To establish the clinical relevance of proprioceptive deficits reported after anterior cruciate ligament (ACL) injury. A literature search was done in electronic databases from January 1990 to June 2009. Inclusion criteria for studies were ACL deficient (ACL-D) and ACL reconstruction (ACL-R) articles written in English, Dutch or German and calculation of correlation(s) between proprioception tests and clinical outcome measures. Clinical outcome measures were muscle strength, laxity, hop test, balance, patient-reported outcome, objective knee score rating, patient satisfaction or return to sports. Studies included in the review were assessed on their methodological quality. In total 1161 studies were identified of which 24 met the inclusion criteria. Pooling of all data was not possible due to substantial differences in measurement techniques and data analysis. Most studies failed to perform reliability measurements of the test device used. In general, the correlation between proprioception and laxity, balance, hop tests and patient outcome was low. Four studies reported a moderate correlation between proprioception, strength, balance or hop test. There is limited evidence that proprioceptive deficits as detected by commonly used tests adversely affect function in ACL-D and ACL-R patients. Development of new tests to determine the relevant role of the sensorimotor system is needed. These tests should ideally be used as screening tests for primary and secondary prevention of ACL injury.

    ABSTRACT: Symptoms of Parkinson's disease (PD) progress despite optimized medical treatment. The present study investigated the effects of a flexibility and relaxation programme, walking, and Nordic walking (NW) on walking speed, stride length, stride length variability, Parkinson-specific disability (UPDRS), and health-related quality of life (PDQ 39). 90 PD patients were randomly allocated to the 3 treatment groups. Patients participated in a 6-month study with 3 exercise sessions per week, each lasting 70 min. Assessment after completion of the training showed that pain was reduced in all groups, and balance and health-related quality of life were improved. Furthermore, walking, and Nordic walking improved stride length, gait variability, maximal walking speed, exercise capacity at submaximal level, and PD disease-specific disability on the UPDRS in addition. Nordic walking was superior to the flexibility and relaxation programme and walking in improving postural stability, stride length, gait pattern and gait variability. No significant injuries occurred during the training. All patients of the Nordic walking group continued Nordic walking after completing the study.

    ABSTRACT: Muscle injuries are common in sports. They are usually caused by either acute (mostly eccentric mechanisms) or chronic overloading with a lack of muscle coordination. They present in clinical practice as bruises and muscle sprains. Due to the rigours of a modern society and the high economic cost of time off work, an effective treatment needs to be employed. The key to an optimised therapy rests in the appropriate timing between immobilisation and mobilisation. The interval to muscle repair might be shortened by certain adjuvant therapies. In doing so, it is important that no physiological phases of wound healing are overlooked. Muscle healing can be accelerated by externally induced higher metabolic turnover. Surgical therapy is sometimes necessary in selected cases and in serious injuries.

    ABSTRACT: Ruptures of the quadriceps or patellar tendon are uncommon but extremely relevant injuries. Early diagnosis and surgical treatment with a stable suture construction are mandatory for a good postoperative clinical outcome. The standard methods of repair for quadriceps and patellar tendon injuries include the placement of suture loops through transpatellar tunnels. Reinforcement with either a wire cerclage or a PDS cord is used in patellar tendon repair. The PDS cord can also be applied as augmentation in quadriceps tendon repair. In secondary patellar tendon repair an autologous semitendinosus graft can be used. For chronic quadriceps tendon defects a V-shaped tendon flap with a distal footing is recommended. The different methods of repair should lead to early functional postoperative treatment. The clinical outcome after surgical treatment of patellar and quadriceps tendon ruptures is mainly good.

    ABSTRACT: Ruptures of the biceps tendon account for a high percentage of tendon ruptures. The aetiology of proximal ruptures of the long head of the biceps tendon is often degenerative and they are frequently associated with lesions of the rotator cuff. The clinical findings are often not specific and long lasting. Distal ruptures of the biceps tendon mostly occur during eccentric contraction of the biceps muscle.Clinical tests, the associated haematoma and a distalisation or proximalisation of the muscle belly in combination with ultrasound or MRI to rule out combined diseases lead to the diagnosis. The possible options include conservative and operative treatment. Tenotomy and tenodesis lead to comparable results in the literature. Therefore, conservative treatment is mostly recommended in proximal ruptures. Operative treatment is preferred in distal ruptures of the biceps tendon in order to achieve an anatomical reconstruction of the muscle function. Chronic ruptures of the distal biceps tendon can be successfully treated with free autografts or allografts.

    ABSTRACT: Betrachtet man die aktuelle Literaturlage zum Thema ärztliche Spielfeldbetreuung, so finden sich nur wenige wissenschaftliche Studien, die sich mit derartigen Inhalten auseinandergesetzt haben. Erfahrungswerte werden von Experten vermittelt und münden in Empfehlungen, die von Fachgesellschaften ausgegeben werden. Grund hierfür ist sicherlich zum einen die große Variabilität hinsichtlich der Anforderungen an die medizinische Betreuung in den verschiedenen Sportarten und -disziplinen auf Grund der unterschiedlichen Verletzungssituationen und -gegebenheiten, zum anderen auch die unterschiedlichen Voraussetzungen, die verletzte Sportler mitbringen. Es ist daher unter wissenschaftlichen Gesichtspunkten nahezu unmöglich, Studien aufzulegen, die diesen Ansprüchen in allen Belangen gerecht werden und zuverlässige Daten liefern. Im Folgenden werden Verhaltensrichtlinien zusammengetragen, die anlässlich unseres Expertenmeetings führender Sportorthopäden und Sporttraumatologen der deutschsprachigen Länder vor dem Hintergrund aktueller wissenschaftlicher Daten erhoben wurden.

    ABSTRACT: Muskelverletzungen sind häufige Verletzungen im Sport und erfordern aufgrund der heutigen Gesellschaft eine effektive suffiziente Behandlung. Hervorgerufen durch akute oder chronische Überbelastung und fehlende Muskelkoordination handelt es sich dabei hauptsächlich um Prellungen und Zerrungen. Eine rechtzeitige Hämatombegrenzung und adäquate Erstbehandlung sind die Grundpfeiler einer kurzen Verletzungsausfallzeit. Im richtigen Timing zwischen Immobilisation und Remobilisation bzw. Progredienz der Remobilisation besteht der Schlüssel für eine optimierte Therapie. In ausgewählten bzw. schweren Fällen ist eine operative Therapie notwendig. Die Muskelreparatur lässt sich durch bestimmte adjuvante Therapien möglicherweise verkürzen, wobei nicht einzelne Phasen übersprungen, sondern alle physiologischen Wundheilungsphasen durch einen extern induzierten höheren Umsatz beschleunigt durchlaufen werden sollten.

    ABSTRACT: Hintergründe: Arthroskopien des Kniegelenks zählen zu den häufigsten orthopädischen Eingriffen. Postoperativ können Schmerzen und Entzündungsreaktionen eine effiziente schnelle Rehabilitation verzögern. Deshalb wurden in den letzten Jahren bereits Medikamente für die intraartikuläre Anwendung ausgetestet, um eine postoperative Analgesie und Entzündungsreduktion zu erreichen. Durch die vorliegende Studie sollten die Wirkungen mehrerer intraartikulärer Medikationen auf die postoperative Frührehabilitation untersucht werden. Methoden: 29 Patienten, die arthroskopisch an den Kniegelenkmenisken operiert wurden, wurden randomisiert und doppelblind auf vier verschiedene Gruppen verteilt. Je nach Gruppenzugehörigkeit bekamen sie nach der Meniskusoperation ein Pharmakon (Hyaluronsäure), eine der beiden Pharmakakombinationen (Morphin/Adrenalin/Dexamethason/Lidocain oder Mepivacain/ Adrenalin) oder keine Medikation injiziert. Ergebnisse: Intraartikuläre Gaben antientzündlich und/oder analgetisch wirkender Medikamente führten zu einer Verbesserung der postoperativen Frührehabilitation nach arthroskopischen Meniskuseingriffen. Die Kombinationsgabe aus Morphin/Adrenalin/Dexamethason/Lidocain führte zu einer signifikanten postoperativen Belastungsschmerzreduktion und einer Verminderung der Muskelatrophie. Die Hyaluronsäuregabe bewirkte eine postoperative Verringerung der Muskelinhibition und der Gelenkschwellung. Die Kombinationsgabe aus Mepivacain/Adrenalin hatte eine Belastungsschmerzreduktion zur Folge. Es traten keine lokalen oder systemischen Nebenwirkungen auf. Schlussfolgerungen: Intraartikuläre Gaben der in dieser Studie verwendeten Medikationen stellen sinnvolle und effektive Therapieformen zur Verbesserung der frühen postoperativen Rehabilitation dar. Die Kombination aus Morphin/Adrenalin/Dexamethason/Lidocain ergab die meisten und deutlichsten Verbesserungen hinsichtlich der postoperativen Frührehabilitation.

    ABSTRACT: Bei vorderen Kreuzbandläsionen im Kindes – und Jugendalter unterscheidet man zwischen knöchernen Ausrissen und reinen Bandläsionen. Erstere werden eher bei präpubertären Kindern beschrieben (Vaquero 2005), während ligamentäre Läsionen häufiger bei pubertären Jugendlichen auftreten (Williams 1996). Letztere betreffen etwa 3–4% aller Rupturen des VKB und ihre jährliche Inzidenz wird auf etwa 1/100.000 Einwohner geschätzt (Janarv 2000). Sie treten selten vor dem 9. Lebensjahr auf und in etwa 3 von 4 Fällen liegt der Verletzung ein Sportunfall zugrunde (Bonnard 2007). Aufgrund der verbesserten klinischen und apparativen diagnostischen Maßnahmen, bei gleichzeitiger Zunahme von Risikosportarten im Kindesalter, werden sie zunehmend diagnostiziert (Aichroth 2002; Mohtadi 2006; Seil 2000).
