Isolated Traumatic Brachialis Muscle Tear: A Case Report and Review of Literature

Abstract

Isolated traumatic brachialis muscle tears are uncommonly reported -leading to occasional misdiagnosis and misdirected treatment. The rarity of brachialis muscle tear may promote misdiagnosis or mistreatment of this injury. We report an isolated brachialis muscle tear in a young female, possibly caused by strenuous exercise in the gymnasium. The diagnosis was made clinically and confirmed by magnetic resonance imaging. The patient was subsequently managed adequately with conservative treatment. We herein present a 35-year-old woman who was diagnosed with an acute brachialis muscle tear being diagnosed with a combination of clinical signs and imaging and successfully managed non-operatively. A chronologically arranged review of literature is also presented.

Brachialis Muscle Rupture in a Pediatric Patient Followed Up by Ultrasound Examinations: A Rare Case Report

“…To the best of our knowledge, there have been 10 case reports of this injury in physically active individuals such as athletes, with ages ranging from 8 to 67 years; additionally, the patients were predominantly male [1][2][3][4][5][6][7][8][9][10]. Reportedly, this injury was commonly caused by an external force forcing the extension of the elbow joint and when the elbow joint was bent due to lifting an object or was forced to extend when performing actions such as tackling in contact sports.…”

“…Conservative and surgical treatments are reported as treatment options; however, there is no standard treatment policy. Among the 10 case reports, 9 were treated conservatively [1][2][3][4][5][6][7][8][9][10]. Surgical treatment was considered in only one patient who was a rugby player.…”

“…A closed rupture of the brachialis muscle is a rare injury [1][2][3][4]. Although some studies have reported this condition in adults, only a few studies have reported it in children [5].…”

Biceps, Brachialis, and Triceps

“…Isolated tears of the brachialis muscle are rare injuries with < 10 cases reported in the literature. 28 Most of the traumatic rupture of the brachialis occurs in elbow hyperextension injuries during which the distal humerus is displaced anteriorly, such as elbow posterior dislocation. 29,30 The brachialis might try to counterbalance the forced elbow extension by contracting in an eccentric way, making it prone to injuries.…”
