Humeral lesser tuberosity avulsion fractures (LTAF) are rare injuries in children. Limited information is available describing MRI characteristics. We aim to describe demographics, mechanism of injury, and MRI findings of LTAF. Read More

This is a case report of a 15-year-old boy with chronic intermittent left shoulder pain due to an undiagnosed lesser tuberosity avulsion fracture, an associated biceps pulley injury and intra-articular dislocation of the long head of the biceps tendon. Also presented is a companion case of a 13-year-old boy with an acute lesser tuberosity avulsion with an intact biceps pulley. Avulsion fractures of the lesser tuberosity are rare injuries which can be difficult to diagnose clinically and on radiographs. Even more rare are reported cases of biceps pulley injuries in children and adolescents with lesser tuberosity avulsions. Utilizing the imaging from these two cases we review lesser tuberosity avulsions in children and also review the complex anatomy of the biceps pulley, which due to its close association with the lesser tuberosity, may be involved in these injuries. These cases emphasize the importance of MR in the diagnosis and treatment planning of lesser tuberosity avulsions. Read More

Recombinant human growth hormone (rhGH) accelerates linear growth but may predispose to physeal stress and injury through accelerated chondrocyte hypertrophy and transient physeal widening. A multitude of musculoskeletal complications include slipped capital femoral epiphysis (SCFE), tibial tubercle avulsion, Osgood–Schlatter disease, Little League shoulder, osteochondritis dissecans, scoliosis, and Sever’s disease. However, sequential multi-physeal injuries in a single patient receiving rhGH are exceedingly rare and not well documented.

We present a 14-year-old male, a baseball player, receiving GH therapy for Idiopathic Short Stature who develops multiple, temporally distinct physeal injuries during two years of active therapy (April 2023 to July 2025).
April 2023: Patient starts GH therapy
July 2023: Left shoulder injury: Radiograph shows widening of the proximal humeral physis consistent with Little League shoulder (Salter–Harris I).
August 2023: Left proximal thigh pain: Radiograph of pelvis demonstrates left inferior pubic ramus fracture and right anterior inferior iliac spine (AIIS) avulsion fracture.
Nov 2023: Left elbow pain with pitching: Radiographs of the elbow consistent with healing lateral epicondyle fracture, with confirmation of capitellar osteochondral lesion on MRI.
April 2024: Right knee injury with x-ray findings consistent with Osgood-Schlatter’s disease.
July 2025: 1.5 months of left hip pain: Pelvic radiograph demonstrates healing of right ischial tuberosity avulsion fracture and right lesser trochanter avulsion fracture.
Notably, the patient has a history of medial epicondyle avulsion fracture (2020) and left AIIS avulsion fracture (March 2023), suggesting pre-existing physeal susceptibility or higher physical exhaustion prior to GH initiation.

This case underscores the importance of potential additive effects of rapid growth (with GH therapy) and repetitive stress. Radiologists should maintain high suspicion for additional or contralateral physeal injuries in GH-treated adolescents, especially those engaged in high-impact sports, and communicate these risks to referring clinicians for coordinated management.
