Reported female breast injuries from 3-point lap-diagonal seat belts have ranged from mild avulsion, recovering completely with conservative breast care, to moderate injuries associated with intramammary hematoma and fat necrosis as seen in our patient, to complete separation of the breast from the chest wall requiring emergency mastectomy. His range of motion had improved, but he complained of some restricted range of motion, particularly with arm abduction.į, front R, rear RFQ, relative frequency of particular injury in comparison to spectrum of injuries noted across several studies. (Fig.2B), 2B), he described a significant reduction in pain from a 6–7 to a 3 out of 10 (10 being severe). Following muscle repair, the remaining glandular and subcutaneous tissues were then repaired in a layered fashion and drains were placed. The muscle repair was completed with interrupted figure-of-eight 0 Ethibond sutures placed at 1 cm intervals and temporarily tensioned with hemostats. Nonviable muscle was debrided and 2 planes of dissection both anterior and posterior to the muscle were completed to allow adequate advancement and approximation of the PM edges as well as overlying breast tissue. A thick capsule containing approximately 50 mL of seroma consistent with the previous magnetic resonance imaging findings of Morel-Lavallee lesion and laterally retracted scarred PM muscle were encountered and excised completely to free the remaining healthy muscle. The rupture was approached through an inframammary incision. Magnetic resonance imaging findings completed in the subacute period were consistent, with scarred soft tissue overlying a rupture through the majority of the medial muscular belly of the left PM sternal head, with lateral retraction and associated Morel-Lavallee lesion consistent with residual hematoma of the chest wall.įor our repair, a left PM muscle block was performed under ultrasound guidance. A computed tomographic scan done at the time of the initial injury showed a complete left medial PM tear with muscle remnant retracted laterally. B, Results at 4 months postoperative.Īpproximately 4 months following the injury, he presented to plastic surgery for an attempted repair of the muscle laceration. A, Preoperative picture showing deformity following traumatic left PM muscle tear resulting from a seat belt injury during motor vehicle collision. ![]() A male passenger presented with severe left chest wall injury. ![]()
