W P Metsaars, M Biegstraaten, R G H H Nelissen
Study Design Retrospective cohort study. Objective Supination deformity in obstetric brachial plexus injury can have debilitating consequences for the functionality of the hand. Surgical treatment by a forearm osteotomy has a recurrence rate of 20 to 42%. As a complement to forearm osteotomy, a biceps rerouting may improve outcome. Methods Children with residual brachial plexus injury, who had a forearm osteotomy for a supination contracture and had a postoperative decrease of pronation to 50 degrees or less, were indicated for a biceps rerouting...

BACKGROUND: Incarcerated medial epicondyle fractures in association with elbow trauma are rare and an absolute indication for intervention. Because of the infrequent nature, outcomes following this injury are not well documented. We studied a large cohort of these injuries to determine factors associated with functional outcomes. It was hypothesized that a greater duration between initial presentation and time of surgery would lead to poorer outcomes. METHODS: A total of 32 patients aged 18 and under who underwent surgical treatment for an incarcerated medical epicondyle fracture at a level-1 pediatric trauma center from 2003 to 2015 were identified...

Pronator teres muscle strain is a rare sporting injury reported thus far only in cricket and golf players. The injury appears to occur when the sporting club or racket strikes the ground during a forceful swing and causes the elbow to experience an eccentric force during resisted elbow flexion and pronation. On initial presentation, this injury can be mistaken for injury to the medial ulnar collateral ligament, or exacerbation of medial epicondylitis. On examination, bruising and tenderness distal to the elbow over the course of the pronator teres are often present...

Hoverboards burst onto the scene with wide popularity only to be quickly deemed unsafe and banned in many arenas. We conducted a retrospective cohort study of 35 patients seen in our outpatient pediatric orthopedic office over a 1-year period. The mean age of injured patients was 11.14 years; 18 patients were male (51.4%), and 17 were female (48.5%). The highest number of injuries occurred in children 10 to 14 years old who had 57.1% of the injuries. There were a total of 31 fractures in 27 patients. Most of the fractures were in the upper extremities (93...

Traumatic elbow dislocations in children are rare but most of them are complex dislocations, and in such dislocations, medial humerus epicondyle fractureis the most common associated injury. Fracture incarceration in the elbow joint occurs in 5-18% of medial humerus epicondyle fractures but ulnar neuropraxia is very rare. Open reduction internal fixation is indicated in medial humerus epicondyle fracture with fracture incarceration, ulnar neuropraxia, marked instability or open fracture. Operative treatment options include fragment excision and sutures, closed or open reduction and Kirschner wire fixation, open reduction and suture fixation, open reduction and smooth pin fixation, and open reduction and screw fixation...

Avulsion fracture of the brachioradialis origin at its proximal attachment on the lateral supracondylar ridge of the distal humerus is exceedingly rare, and only two cases have been reported in the literature so far. In this article, we present a 38 years old patient who sustained a closed avulsion fracture of the lateral supracondylar ridge of left humerus at the proximal attachment of brachioradialis following a fall backwards on outstretched hand after being struck by a lorry from behind while riding on a two-wheeler (motorcycle)...

OBJECTIVE: Competitive bass angling involves sport fishing against other anglers while targeting a species of fish known as the black basses. Due to the rapidly growing popularity of high school competitive bass angling in Alabama and the nature of the casting motion similar to that of overhead athletes, we sought to examine the prevalence of sports type injuries in this population. METHODS: In spring 2016, an anonymous survey was distributed across two large scale competitive high school fishing tournaments, allowing for a broad sampling of anglers throughout the state of Alabama...

PURPOSE: Magnetic resonance imaging (MRI) of medial collateral ligament (MCL) injury of the elbow was often observed in asymptomatic adolescent baseball players. We aimed to clarify the clinical interpretation of "asymptomatic MCL injury observed on MRI" by comparing MRI, ultrasonography (US), and physical findings. MATERIALS AND METHODS: Sixty-four asymptomatic adolescent baseball players (mean 11.2 years) were enrolled. An open-type 0.2T MRI was used. MCL function was evaluated by measuring the opening of the ulnohumeral joint using US...

The elbow joint is highly susceptible to joint contracture, and treating elbow contracture is a challenging clinical problem. Previously, we established an animal model to study elbow contracture that exhibited features similar to the human condition including persistent decreased range of motion (ROM) in flexion-extension and increased capsule thickness/adhesions. The objective of this study was to mechanically quantify pronation-supination in different injury models to determine if significant differences compared to control or contralateral persist long-term in our animal elbow contracture model...

INTRODUCTION: The median and radial nerves are two important neural structures found in the cubital fossa. The trajectory and landmarks used to identify their location are important when procedures are done in this area. METHODS AND MATERIALS: Ten fresh-frozen cadavers were dissected (20 upper limbs) and measurements were taken from the medial epicondyle to the median and radial nerves as well as to the lateral epicondyle of each limb. RESULTS: The distance between the medial epicondyle and the median nerve was found to be three centimeters with a range of 2...

OBJECTIVE: Clinical and functional assessment of the surgical treatment for acute injury of the distal insertion of the biceps brachial performed with a surgical technique using a single incision in proximal forearm and fixation with suture anchors in the radial tuberosity. METHODS: This study reviewed the medical records of patients who underwent surgical treatment of distal biceps injury during the period between January 2008 and July 2014. In a mean follow-up of 12 months, 22 patients with complete and acute injury, diagnosed through physical examination and imaging studies, were functionally assessed in the postoperative period regarding the range of motion (degrees of flexion-extension and pronation-supination), the presence of pain (VAS), the Andrews Carson-score, and the Mayo Elbow Performance Score (MEPS)...

Andrew M Choo, Patrick C Schottel, Andrew R Burgess
Scapulothoracic dissociation is a rare, potentially limb- and life-threatening injury of the shoulder girdle. The injury is characterized by lateral displacement of the scapula resulting from traumatic disruption of the scapulothoracic articulation. The typical physical examination findings consist of substantial swelling of the shoulder girdle, along with weakness, numbness, and pulselessness in the ipsilateral upper extremity. Radiographic evaluation includes measurement of the scapular index on a nonrotated chest radiograph and assessment for either a distracted clavicle fracture or a disrupted acromioclavicular or sternoclavicular joint...

BACKGROUND: Isolated coronoid, isolated radial head, and combined coronoid and radial head fractures are common elbow fractures, and specific ligamentous injury of each fracture configuration has been reported. However, the osseous injury mechanism related to ligament status remains unclear. QUESTIONS/PURPOSES: The objectives of this study were: (1) to determine what ligamentous injury patterns (medial or lateral collateral) and bone contusion patterns (medial or lateral) are associated with isolated coronoid, isolated radial head, and combined coronoid and radial head fractures; (2) to correlate the osseous injury mechanism based on these findings with isolated coronoid, isolated radial head, and combined coronoid and radial head fractures; and (3) to determine whether isolated and combined coronoid fractures have different fracture lines through the coronoid (tip or anteromedial facet), speculated to be caused by different injury mechanisms...

Humeral cement removal in revision shoulder arthroplasty can be challenging. Secondary damage to the bone and neighbouring structures can be extensive and compromise later reconstruction. We present a technique that employs flexible reamers from elbow arthroplasty instrumentation, which aids cement removal at the same time as minimizing the risk of iatrogenic injury.

BACKGROUND: Injury rates among professional baseball players may reach as high as 5.8 per 1000 encounters, with pitchers being most vulnerable on account of the excessive biomechanical load on the upper extremity during the throwing motion. Anatomically, the shoulder is the most common site of pitching-related injury, accounting for 30.7% of injuries, closely followed by the elbow at 26.3%. Characteristic valgus loading imparts a predictable constellation of stresses on the joint, including medial tension, lateral compression, and posterior medial shearing...
