- Abstract:
- Introduction: Tumors of the clavicle are extremely rare. Therapy involves wide resection of the lesion or even the entire clavicle. The shoulder joint is considered to be the most complex joint in the human body, as all its components are in close interaction. The aim of this diploma thesis was to analyze the influence of a tumor resection of the clavicle and thus a disturbance of the biomechanics of the shoulder joint on the clinical, oncological and functional outcome of the patients. Materials and Methods: Between 2000 and 2018, a total of seven patients (n=7) were treated at the Department of Orthopaedics and Trauma at the Medical University of Graz, Austria, because of a tumor affecting the clavicle. Six of these patients were included in the retrospective analysis because a wide resection of the tumor was performed. (n=6) Patient-, tumor- and treatment-associated factors, as well as patient survival were investigated. In the prospective part two of the patients could be reexamined. The functional outcome in the prospective part was assessed and described by clinical examination, the common tests for the assessment of shoulder function and by the two questionnaires Quick-DASH- and MSTS-Score. Results: One of the patients had the lateral part of the clavicle removed because of spindle cell sarcoma. The other five patients underwent resection of the entire clavicle, two patients due to Ewing sarcoma, two due to osteosarcoma, and one due to Merkel cell carcinoma metastasis. At a mean follow-up time of 5.3 years, four patients were alive and mostly symptom-free with good upper limb mobility. One patient complained of pain in the surgical area and of problems lifting heavy objects. The two patients in the prospective part were free of complaints with good shoulder functionality, and Quick-DASH- Scores of 2.27 and 34.09, and MSTS-Scores of 100 and 86.67, respectively. Conclusion: Although the clavicle is a component of the complex interaction of upper extremity joints and movements, resection of the clavicle can be accomplished with satisfactory results and without serious loss of function.
