Abstract
e20634 Background: Axillary lymph node dissection is an inevitable part of breast cancer surgery in certain cases. Definitive data regarding the incidence of postoperative winged scapula remains inconsistent. Ignorance of its diagnosis may lead to under-treatment and result in physical morbidity. Methods: All breast cancer patients who underwent axillary lymph node dissection procedures were recruited. In the early postoperative period, within 24 hours after surgery, the physiotherapy staff performed physical examinations to evaluate and identify the physical signs of long thoracic nerve injury by means of two specific orthopedic evaluation tests. The factors that may relate to winged scapula were recorded and analyzed. Results: From July to October 2012, 51 out of 187 patients were diagnosed with winged scapula (27.2%). The median age was 49.0 years old. 130 patients had undergone mastectomy and 100 cases had immediate breast reconstruction. Age, BMI, history of shoulder joint morbidity and previous breast surgery were not significantly associated with winged scapula. Administration of neoadjuvant treatment, mastectomy or breast conservative surgery, immediate reconstruction and its type, tumor size and nodal involvement also did not show any correlation. Conclusions: The winged scapula is not an infrequent sequela after axillary lymph node dissection in the breast cancer patient. It is usually underestimated and overlooked. There is no association between age, BMI, neoadjuvant treatment, type of breast surgery, tumor size or nodal stage. As breast reconstruction plats an ever-increasing role in current breast surgery practice it is interesting to note that reconstruction with prosthesis, even with serratus muscle dissection does not increase the incidence of winged scapula. Post reconstruction morbidity could interfere with the physical evaluation and outcome, but the result of our subgroup analysis showed no significant correlation among them. In our clinical experience, this sequela is not irreversible, being a transitory problem. Our series show only immediate 24 hr result that lack of long term follow-up and still need physical therapy proctocols to evaluate the recovery.
