Management and Treatment of Elbow and Forearm Injuries
Emergency Medicine Clinics of North America, 2010
Orthopedic injuries to the upper extremity are frequently seen in the emergency department (ED). The emergency medicine practitioner (EP) must be proficient in recognizing these injuries and their associated complications, and be able to provide appropriate orthopedic management. This article highlights the most frequent forearm and elbow injuries seen in the ED. FOREARM ANATOMY Two bones form the forearm, the radius (lateral) and ulna (medial). The elbow capsule holds both bones together proximally while the anterior and posterior radioulnar ligaments carry out the same task in the distal radioulnar joint (DRUJ). The forearm muscles, pronator quadratus, pronator teres, and supinator also help maintain the unified movement of bones. The interosseous membrane further stabilizes both bones, while dividing the forearm into the flexor and extensor muscle compartments. The median nerve or its anterior interosseous branch innervates all the flexor muscles except for the flexor carpi ulnaris and the ulnar aspect of the flexor digitorum profundus, which are innervated by the ulnar nerve. The anterior interosseous nerve

Supracondylar humerus fractures are very common types of elbow fractures in children between the ages of three and ten years. Totally displaced supracondylar humerus fractures can be associated with neurovascular injuries, and treatment can be complicated by iatrogenic neurovascular injury, compartment syndrome, malunion, and elbow stiffness. The aim of this study was to describe the clinical outcome of nerve injuries associated with supracondylar humerus fractures in children observed over a period of seven years. Children with displaced supracondylar humerus fracture who were treated with closed reduction and percutaneous cross K-wire fixation were reviewed retrospectively at the Medical School Hospital of Yuzuncu Yil University from May 2004 to October 2012. There were 91 patients available for follow-up. Nerve injury was observed in 11 (12.1%) of 91 patients with supracondylar humerus fractures. In 10 (90.1%) of these 11 cases, nerve functions recovered completely (excellent out...
Total elbow anthroplasty and distal humerus elbow fractures
Hand Clinics, 2004
The indications for total elbow arthroplasty (TEA) have expanded over the last few decades. The initial primary indication for TEA was inflammatory arthritis of the elbow; however, more recently there have been reports on the successful use of TEA for other clinical situations, such as post-traumatic or primary osteoarthritis, nonunion or malunion of the distal humerus, and comminuted distal humerus fractures in elderly patients. As the indications for TEA have expanded, unfortunately the incidence of complications and implant failure also has increased. In 1994 Kraay et al reported their cumulative survival of TEA for post-traumatic arthritis, fractures, or supracondylar nonunion at 3 and 5 years compared with a second group of TEA in patients with inflammatory arthritis. The cumulative survival in the first group was 73% and 53% at 3 and 5 years, respectively, compared with 92% and 90% for the inflammatory group. This has raised concerns for expanding indications of TEA beyond patients with inflammatory arthritis. This article addresses the issues around TEA in the setting of comminuted distal humerus fractures in elderly patients and provides a review of the recent literature on this subject.

According to the AO classification, five fractures were type A, five type B, and 33 type C. The average flexion arc at follow-up was 24–131°, the Mayo Elbow Performance Score averaged 93. Data of complications were obtained from records in all 49 patients. 32 of the 49 elbows had neither a complication nor any further surgery from the time of the index arthroplasty to the most recent follow-up evaluation. Ten additional operative procedures, including five revision arthroplasties, were required. The retrospective review supports recommendation for TER for the treatment of an acute distal humeral fracture, when strict inclusion criteria are observed.
Open Elbow Arthrolysis for Post-traumatic Elbow Contracture
Upsala Journal of Medical Sciences, 2008
Background: Post-traumatic contracture is a common complication after elbow trauma. If conservative therapy fails to restore adequate elbow motion, arthrolysis is indicated. The purposes of this study were to evaluate the clinical outcome of open arthrolysis for post-traumatic elbow contracture and to determine factors influencing the outcome. Methods: Twenty-seven patients with post-traumatic elbow contracture were followed-up after open arthrolysis for at least 12 months. Before surgery, the mean limitation in extension was 30° and the mean maximum flexion was 83°. A posterior surgical approach was used in 18 patients, and a lateral approach was employed in nine patients. Using the posterior approach, the fibrotic posterior capsule was excised and the ulnar collateral ligament was split. Both the anterior and posterior capsules were released with a lateral approach. Results: The mean flexion increased from 83° to 121°, but the mean extension improved little from-30° to-26°. The mean flexion-extension arc increased from 53° to 95°. According to the elbow evaluation score by the Japanese Orthopaedic Association, both pain and function scales improved significantly. By Hertel's subjective evaluation, the results were good in 13 patients, fair in ten patients, and poor in four patients. Twenty-three patients (85 percent) were satisfied with the results, but four were not satisfied because of residual contracture. These poor results were related to severe soft tissue trauma, residual displacement of intra-articular fragments, and recurrence of heterotopic bone formation. Conclusions: Tendon lengthening of stiff triceps, accurate reduction of intra-articular fragmens, and sharp epiperiosteal resection around the heterotopic bones are essential procedures of open arthrolysis to restore adequate motion in post-traumatic elbow contracture.
