1-which shoulder dislocation has the MC incidence of neurovascular injury?2-inferior dislocation of the glenohumeral joint aka
A 35-year-old male injured his right shoulder while playing basketball. He presents emergently with significant pain and his shoulder abducted at 140 degree. He is unable to lower his arm. Radiographs will most likely show that his glenohumeral joint has dislocated in what direction?1. Anterior2. Posterior3. Superior4. Inferior5. Lateral
A 26-year-old right hand dominant male is involved in a motor vehicle collision and sustains the left humerus injury demonstrated in Figure A. The brachial artery is disrupted and requires urgent attention in the operating room. The patient's preoperative nerve evaluation demonstrates that the patient is unable to initiate extensor carpi radialis longus, extensor carpi radialis brevis, extensor pollicis brevis, extensor indicis proprius, and extensor pollicis longus motor activity. What is the most likely etiology for this observed neurologic examination?1. Neurapraxia of the median nerve2. Axonotmesis of the radial nerve3. Neurotmesis of the ulnar nerve4. Neurotmesis of the radial nerve5. Axonotmesis of the ulnar nerve
MCC radial nerve palsy in a high energy open hum fx is laceration or complete disruption of the radial nerve (Neurotmesis). Neurotmesis is complete disruption of nerve and is assoc w/ no spontaneous recovery w/out intervention. Axonotmesis constitutes axon disruption, but the surrounding neural connective tissue is intact & nerve regeneration can occur(Wallerian or antegrade degeneration). Neurapraxias occur often by compression & axon maintains continuity but local demyelination and ischemia occur. All 6 patients with a transected radial nerve had an open humerus fracture also. The results of primary nerve repair in this circumstance found that there was no recovery in any of the pts.Incorrect Answers:Answer 1,3,5: The radial nerve provides distal motor activity to the ECRL, ECRB, EPB, EIP, and EPL.Answer 2: Axonotmesis of the radial nerve is not the most common form of injury associated with closed or open humerus fractures.Ans4
A 45-year-old male sustains a Gustilo and Anderson Type II open transverse humeral shaft fracture. He undergoes the treatment shown in Figures A and B. What is the advantage of this treatment choice as compared to antegrade intramedullary nailing?1. Decreased risk of post-operative elbow pain2. Decreased risk of radial nerve injury3. Decreased risk of reoperation4. Decreased risk of infection5. Decreased risk of blood loss
During an open reduction internal fixation of a humerus fracture using the posterior approach, a surgeon can identify the posterior antebrachial cutaneous nerve and trace it proximally to which of the following nerves?1. Ulnar2. Musculocutaneous3. Radial4. Median5. Axillary
Which of the following is a known risk factor for the development of adhesive capsulitis of the shoulder?1. Menopause2. Steroid use3. Diabetes mellitus4. Renal disease5. All of the above
