Die Gefahr einer solchen Verletzung besteht vor allem w\u00e4hrend der exzentrischen Phase der Muskelbelastung. Ein Zusammenhang mit dem Missbrauch von anabolen Steroiden wird beschrieben, die Datenlage hierzu ist allerdings inkoh\u00e4rent. Wir berichten \u00fcber den besonderen Fall eines jungen Patienten mit normalem Habitus, der sich im Rahmen des Breitensports eine humerale Ruptur des M. pectoralis major zugezogen hat. Anamnestisch bestand weder eine exzessive Kraftsportaus\u00fcbung noch ein Anhalt f\u00fcr die Einnahme anaboler Steroide.<\/jats:p><jats:p>\n          Kasuistik Der 33-j\u00e4hrige Patient berichtete \u00fcber pl\u00f6tzlich einschie\u00dfende Schmerzen links pektoral beim Training am Butterfly-Ger\u00e4t sowie ein peitschenartiges Knallger\u00e4usch, danach h\u00e4tte initial eine schmerzhafte Bewegungseinschr\u00e4nkung des linken Arms bestanden. Klinisch zeigten sich eine leichte H\u00e4matomverf\u00e4rbung am linksseitigen medialen Oberarm mit lokalem Druckschmerz sowie eine diskrete Asymmetrie der Kontur der Brustmuskulatur. Aufgrund der typischen Anamnese stellten wir trotz eher diskreter Klinik und laut MRT-Befundung inkompletter Ruptur die Indikation zur operativen Exploration. Intraoperativ fand sich eine vollst\u00e4ndige Ruptur der Pars sternocostalis des M. pectoralis major mit deutlicher Retraktion und H\u00e4matomeinblutung. Es erfolgte die Armierung und Reinsertion am Footprint mittels Titan-Ankern (2x 5,5mm Corkscrew FT Fa. Arthrex, Florida). Nach Abschluss der Rekonvaleszenzphase konnte der Patient seine sportlichen Aktivit\u00e4ten auf pr\u00e4traumatischem Niveau wieder aufnehmen.<\/jats:p><jats:p>\n          Schlussfolgerung Auch bei Breitensportlern muss bei typischer Anamnese an eine Ruptur des Ansatzes des M. pectoralis major gedacht werden. Die in der Literatur beschriebene typische klinische Symptomatik bezieht sich vorwiegend auf Leistungssportler und Bodybuilder; auch beim Breitensportler kann jedoch mittels subtiler Untersuchung eine korrekte Diagnose gestellt werden. Es besteht dennoch eine erhebliche Gefahr, das Ausma\u00df der Verletzung zu untersch\u00e4tzen. Im Zweifel sollte auch beim Breitensportler eine zeitnahe operative Exploration erfolgen. Die operative Refixierung der humeralen Ruptur des M. pectoralis major stellt den Goldstandard dar und sollte nicht nur Hochleistungsathleten vorbehalten bleiben.<\/jats:p>","DOI":"10.1055\/a-1754-4524","type":"journal-article","created":{"date-parts":[[2022,4,12]],"date-time":"2022-04-12T23:29:33Z","timestamp":1649806173000},"page":"155-159","source":"Crossref","is-referenced-by-count":1,"title":["Die
