Abstract

There has been an increase in thrower-specific elbow injuries in recent years. High valgus stresses during the late cocking and acceleration phases of throwing need to be compensated by the flexor pronator muscles as these can exceed the tensile strength of the medial collateral ligament complex. Prevention of injuries is the priority, with a focus on strengthening, reducing throwing frequency, decreasing force, and promoting a technique. The spectrum of thrower injuries ranges from a simple sprain to complete failure of the valgus stabilizing factors. The medial collateral ligament can stretch, leading to posteromedial impingement and radiocapitellar compression forces. This in turn can result in arthrosis and the formation of osteophytes. Ligament failure may eventually occur, making it impossible for the athlete to continue their throwing activities. The outcome of conservative treatment with strengthening, improvement of technique, and relative rest is often disappointing. Direct repair may no longer be possible in these acute-on-chronic injuries and a reconstruction with a tendon graft may be necessary.

肘关节外翻不稳定:急性和慢性形式。

近年来，投掷运动员特有的肘部损伤有所增加。高外翻应力在投掷的后期翘起和加速阶段需要由屈肌前旋肌来补偿，因为这些肌肉可能超过内侧副韧带复合体的拉伸强度。预防伤害是优先考虑的，重点是加强，减少投掷频率，减少力量，并促进技术。投掷者受伤的范围从简单的扭伤到外翻稳定因素的完全失效。内侧副韧带可以拉伸，导致内侧后撞击和桡肱压迫力。这反过来又会导致关节病和骨赘的形成。最终可能会发生韧带损伤，使运动员无法继续进行投掷活动。采用强化、技术改进和相对休息等保守治疗的结果往往令人失望。在这些急性慢性损伤中，直接修复可能不再可能，可能需要用肌腱移植重建。

期刊介绍： Zielsetzung der Zeitschrift Die Zeitschrift Obere Extremität widmet sich der Versorgung von Verletzungen, Verletzungsfolgen und Erkrankungen im Bereich des Schulter- und des Ellenbogengelenks. Frei eingereichte Originalien präsentieren Forschungsergebnisse aktueller Studien im Bereich der Schulter- und Ellenbogenchirurgie und fördern den wissenschaftlichen Austausch. Vielversprechende Studien, die derzeit durchgeführt werden, sind ebenso willkommen, wie Langzeitstudien, die bewährte Verfahren auf den Prüfstand stellen. Fallberichte beleuchten seltene Indikationen und schildern ungewöhnliche Behandlungsverläufe. Umfassende Übersichtsarbeiten zu einem aktuellen Schwerpunktthema sind das Kernstück jeder Ausgabe. Im Mittelpunkt steht gesichertes Wissen mit hoher Relevanz für die tägliche Arbeit in der Schulter- und Ellenbogenchirurgie. Zusätzlich wird in speziellen Rubriken über innovative Behandlungsmaßnahmen, Probleme in der Begutachtung, berufspolitische Entwicklungen und Kongressaktivitäten berichtet. Als gemeinsames Kommunikations- und Weiterbildungsforum für alle Chirurg*innen und Orthopäd*innen mit entsprechender Spezialisierung ist die Zeitschrift Obere Extremität zukunftsorientiert und schließt eine wichtige Lücke im orthopädisch-unfallchirurgischen Informationsangebot. Aims & scope The journal Obere Extremität (Upper Extremity) is dedicated to the treatment of injuries, consequences of injuries and diseases in the area of the shoulder and elbow joint. Freely submitted originals present research results of current studies in the field of shoulder and elbow surgery and promote scientific exchange. Promising studies that are currently being carried out are welcome, as are long-term studies that put proven procedures to the test. Case reports illuminate rare indications and describe unusual courses of treatment. Comprehensive reviews on a current focus topic are the core of each issue. The focus is on secured knowledge with high relevance for the daily work in shoulder and elbow surgery. In addition, special sections report on innovative treatment measures, problems in assessment, professional policy developments and congress activities. As a joint communication and further education forum for all surgeons and orthopaedic surgeons with appropriate specialisation, the journal Obere Extremität is future-oriented and closes an important gap in the orthopaedic trauma surgery information offer. Begutachtung / Peer Review Alle Beiträge, die bei der Zeitschrift Obere Extremität eingereicht werden (einschließlich der eingeladenen Manuskripte) durchlaufen ein Doppelblind-Peer-Review-Verfahren, an dem mindestens zwei unabhängige Experten beteiligt sind.--- All manuscripts submitted to the journal Obere Extremität (including invited manuscripts) undergo a double-blind peer review process involving at least two independent experts. Ethische Richtlinien / Best Practice Guidelines and Publication Ethics Die Zeitschrift Obere Extremität folgt den Richtlinien des Komitees für Publikationsethik (COPE). Autoren wird empfohlen, klinische Studien, die sie zur Veröffentlichung in Betracht ziehen, vor der Veröffentlichung in kostenlosen, öffentlichen Registern für klinische Studien (z.B. www.clinicaltrials.gov, http://clinicaltrials.ifpma.org, http://isrctn.org, www.germanctr.de/online-Register_de.html) zu registrieren. Die Register sind nach den Richtlinien des International Committee of Medical Journal Editors (ICMJE) zu genehmigen. Die Autor*innen sollten am Ende ihres Abstracts den Namen des Studienregisters und ihre Registriernummer für klinische Studien angeben. The journal Obere Extremität (Upper Extremity) follows the Committee of Publications Ethics (COPE) - Guidelines. Authors are recommended to register clinical trials they consider for publication in free, public clinical trial registries (e.g., www.clinicaltrials.gov, http://clinicaltrials.ifpma.org, http://isrctn.org, www.germanctr.de/online-Register_de.html) before publication. The registries are to be approved by the guidelines of the International Committee of Medical Journal Editors (ICMJE). Authors should include the name of the trial register and their clinical trial registration number at the end of their abstract. Deklaration von Helsinki / Declaration of Helsinki Alle zur Veröffentlichung eingereichten Manuskripte, die Ergebnisse von Studien an Proband*innen oder Patient*innen präsentieren, müssen gemäß den Autorenrichtlinien für Originalarbeiten der Deklaration von Helsinki entsprechen. All Manuscripts submitted for publication presenting results from studies on probands or patients must comply with the Declaration of Helsinki according to the author guidelines for original papers.
