Introduction Congenital dislocation of radial head can bedifferentiated from a traumatic dislocation by: bilateral involvement hypoplastic capitellum convex radial head other congenital anomalies lack of history of trauma difficult to reduce Pathoanatomy almost always posterior dislocation of radial head often combined with bowing and shortening of radius Associated conditions may have concurrent congenital anomalies Anatomy Elbow Anatomy & Biomechanics Presentation Symptoms patients often asymptomatic limited elbow ROM Physical exam radial head prominence can have limited elbow ROM especially in extension and supination usually painless Imaging Radiographs radial head posterior to capitellum radial head can be large and convex radius is short and bowed Treatment Nonoperative observation indications first line of treatment Operative radial head resection indications usually done in adulthood if patient has significant pain restricted motion cosmetic concern of elbow outcomes reduces pain may improve some elbow ROM
QUESTIONS 1 of 3 1 2 3 Previous Next (OBQ13.143) A 17-year-old boy presents with pain in his right elbow for 2 years and limitation in elbow motion bilaterally. He denies any pain or discomfort in his left elbow. He reports no history of trauma to either elbow. He has had two courses of physical therapy, but has noted no noticeable improvement in pain or motion. Examination demonstrates no elbow tenderness on palpation, and there are no neurological deficits. Manual reduction is unsuccessful. The range of motion of both elbows is shown in Figure A. Radiographs of left and right elbow are shown in Figure B and C respectively. What is the most appropriate treatment plan for the right and left elbow? Review Topic QID: 4778 FIGURES: A B C 1 Bilateral open reduction and application of a hinged external fixator to both elbows 3% (72/2567) 2 Radial head resection of the right elbow and non-operative management of the left elbow. 82% (2096/2567) 3 Bilateral radial head arthroplasty 3% (80/2567) 4 Physical therapy and splinting to both elbows 7% (174/2567) 5 Radial head resection and interposition arthroplasty for the right elbow and radial head resection alone for the left elbow 5% (135/2567) ML 2 Select Answer to see Preferred Response PREFERRED RESPONSE 2 Sorry, this question is for PEAK Premium Subscribers only Upgrade to PEAK Sorry, this question is for PEAK Premium Subscribers only Upgrade to PEAK
