Fly Fishing-related lesser tuberosity avulsion in an adolescent.
Stress lesions of the shoulder in athletic and active adolescents are most commonly associated with overhead sports. One of the most uncommon stress lesions of the shoulder in adolescents is an avulsion of the lesser tuberosity of the proximal humerus. To our knowledge, only 2 other cases of lesser tuberosity avulsions from repetitive motion have been reported, both of which were secondary to b...
متن کاملAbnormalities of the lesser tuberosity on radiography and MRI: association with subscapularis tendon lesions.
OBJECTIVE The objective of our study was to retrospectively evaluate the association between abnormalities of the lesser tuberosity and subscapularis tendon lesions. MATERIALS AND METHODS Cortical irregularities and cysts of the lesser tuberosity were evaluated on radiographs and MR images in 70 patients: 31 with normal subscapularis tendons and 39 with subscapularis tendon tears. These imagi...
متن کاملIsolated avulsion fracture of the lesser tuberosity of the humerus.
Three cases of isolated avulsion fracture of the lesser tuberosity are described together with a review of six previously reported cases. Of the total cases, six had a well-documented mode of injury, in which a strong abducting force was applied to the medial aspect of the upper arm, causing exaggerated abduction and external rotation. The contracting subscapularis muscle displaces the avulsed ...
متن کاملSubscapularis Tears and Lesser Tuberosity Avulsion Fractures in the Pediatric Patient
BACKGROUND Pediatric subscapularis tears are known to be rare injuries. They are often associated with an avulsion fragment of the lesser tuberosity leading to dual description in the literature of either subscapularis tear or lesser tuberosity avulsion. Historically, they were managed nonoperatively; however, outcomes have improved with operative management. Nonoperative management often led t...
متن کاملEffect of lesser tuberosity osteotomy size and repair construct during total shoulder arthroplasty.
BACKGROUND Lesser tuberosity osteotomy has been shown to decrease postoperative subscapularis dysfunction. The purpose of this study was to determine the effect of osteotomy thickness and suture configuration on repair integrity. MATERIALS AND METHODS One side of 12 matched-pair cadaveric shoulders was randomly assigned to either a thick osteotomy (100% of lesser tuberosity height) or a thin ...
