Scapular Winging and Multi-Directional Shoulder 
Instability in a Collegiate Women’s Gymnast
Abstract
A 20-year-old Caucasian collegiate women’s gym-
nast presented with a previous history of shoulder 
instability. A specialist in the uneven bars event, the 
gymnast required increased mobility to perform 
specific skills. The athlete presented with an inferior 
shoulder dislocation event after warming up at a 
competition. After clinical evaluation, the differential 
diagnoses included chronic subluxation, severe 
scapular winging, and multi-directional instability. 
The athlete underwent rehabilitation and diagnostic 
imaging which demonstrated labral tearing. An 
electromyography (EMG) test was performed which 
was normal. Continued physical therapy was 
performed.  The patient had significant disability with 
daily activities and did not progress with a dedicated 
therapy program. Surgery was performed and the 
athlete demonstrated significant improvements in 
function but decided not to return to gymnastics.
Introduction 
Shoulder injury occurrence is common in college 
sport participation. The National Collegiate Athletic 
Association (NCAA) works with college athletic 
trainers to monitor injury rates and occurrences in 
NCAA sports. This program is known as the Injury 
Surveillance Program (ISP) and started in 1982.10 
Hootman et al. noted upper extremity injuries were 
around 20% of all injuries reported over 15 sports in 
16 years. In the gymnastics injury surveillance report 
from 2014-2019, out of all injuries accounted for, 
9.2% were shoulder injuries.9 Commonly noted 
shoulder pathologies in the sport of college gymnas-
tics include rotator cuff tendinitis/tendinopathy, labral 
and biceps tendon pathology, instability/subluxation, 
multidirectional instability (MDI), and sprain/strain 
injuries.11 While most may not consider gymnastics 
when thinking of an upper extremity sport, the 
incidence of shoulder injuries is still prevalent. In 
women’s gymnastics, there is increased torque placed 
through the shoulder complex and arms in all events, 
including the uneven bars. Due to the repetitive 
nature of the sport, upper extremity injuries are 
typically from overuse. 
Circumferential labral lesions represent about 2.4% 
of all labral lesions, thus underlining the rarity of this 
clinical case report.5-6 A detailed history and clinical 
evaluation is important in the diagnosis of any injury. 
Overuse injuries can often be managed with rest, 
rehabilitation, and non-steroidal anti-inflammatory 
drugs (NSAIDs). If conservative treatment of an 
injury does not provide a patient with relief, then 
referral to an orthopedic physician for further evalua-
tion and diagnostic imaging is warranted. This 
clinical case report provides evidence of a rare 
shoulder diagnosis in the athletic training and sports 
medicine worlds.
Case Presentation
A 20-year-old Caucasian collegiate women’s gym-
nast presented with a previous history of shoulder 
instability. She noted that she had previously gone 
through general rehabilitation for her shoulder, but it 
had not helped much. At the time of evaluation, the 
patient was in the beginning of her junior season. The 
athletic trainer’s evaluation revealed severe scapular 
winging, multi-directional instability, and the patient 
could actively self-sublux her shoulder. (Figures 1 
and 2). There was mild instability present on the 
contralateral side as well, but the patient had not 
experienced decreased function like the affected side. 
Key Points:    
 1. Multidirectional instability can lead to severe scapular winging 
 2. Conservative treatment may not work for chronic shoulder subluxation with multi-directional instability.
 3. Circumferential labral tears are rare, but should be included in differential diagnoses.
