title: [Considerations of biomechanics after clavicular resection. Case report of rower with Ewing sarcoma].
abstract: Because of poorly compartmentalized paraclavicular soft tissues, total extraperiostal claviculectomy in cases of malignoma with cortical destruction is always marginal. Due to different muscular compensation in the patients examined, literature disagrees on the biomechanical consequences of claviculectomy for the shoulder girdle. We present a case of total clavicula resection including chemotherapy and radiation in an 18-year-old rower with Ewing's sarcoma. Sixteen-month postoperative radiological and clinical examination revealed an excellent result. Thirty-six months postoperatively the patients is able to row symptom-free without any evidence of the disease. Biomechanical reflections on the significance of the trapezius muscle in compensating thoracoscapular instability provide information for rehabilitation.
