Of the humerus. A four-part displaced proximal humerus fracture in a 70-year-old, active, healthy female with osteoporosis should be treated with: a. Which of the following is true regarding minimally displaced proximal humerus fractures Mechanisms of injury include tumor, surgical procedures to the posterior triangle, and stretch and whiplash injuries. The most common mechanism of injury to the accessory nerve is iatrogenic during lymph node biopsy in the posterior triangle of the neck. Describe the typical presentation of a patient with a spinal accessory nerve injury. The patient�s symptoms may include a drooping shoulder girdle and/or flat upper trapezius muscle on the involved side. Shoulder pain is a major disabling factor, often attributed to traction at the brachial plexus. Winging of the scapula caused by trapezius weakness increases with abduction, whereas winging caused by serratus anterior weakness increases with forward elevation. If the level of injury is above the innervation of the sternocleidomastoid, the patient also may demonstrate weakness in rotating the face toward the opposite shoulder. Symptoms may seem to mimic shoulder dysfunction, with pseudo weakness of the rotator cuff secondary to decreased stability of the scapula, which, in turn, can contribute to rotator cuff pathology. Delayed diagnosis of a spinal accessory nerve injury as the cause of shoulder pain remains a common problem, particularly in iatrogenic injuries. An electrophysiologic evaluationis requiredto precisely identify the level of the lesion and assess for the potential for regeneration. Electrophysiologic testing will also reveal the degree of damage and, in particular, whether
