文摘

Forequarter amputation (FQA) is reserved for large, multifocal, or recurrent tumors affecting the shoulder and upper extremity. Although it is performed less frequently with the advancement of limb salvage surgery, FQA remains an important treatment in select patients. The purpose of this study is to illustrate the surgical technique in a case series of 4 patients.

Methods

5">Between 2010 and 2012, 4 patients (mean age, 61 years; range, 36-78 years) presented with malignant disease of the upper extremity that was not amenable to or had failed limb salvage. All patients had FQA by the illustrated anterior clavicular osteotomy technique. Patient data were retrospectively reviewed from preoperative workup until last follow-up or death.

Results

All patients had tumors that involved major neurovascular structures of the upper extremity and shoulder girdle. One presented with neuroendocrine carcinoma and has achieved local control after FQA. Three presented with high-grade sarcoma. One of these had recurrence after prior limb salvage and neoadjuvant radiation and unfortunately succumbed to metastatic disease 6 months after FQA. An additional sarcoma patient who presented after shoulder arthroscopy for a “labral cyst” with recurrent and fulminant synovial sarcoma succumbed to her disease. The remaining sarcoma patient has had no recurrence and minimal phantom pain at last follow-up.

Discussion

5">Obtaining vascular control early in the procedure is crucial to minimize blood loss. When it is indicated, FQA is a relatively safe and reliable procedure for dealing with otherwise challenging tumors of the shoulder girdle and upper extremity.
