Shoulder Injuries in the Throwing Athlete
Treatment by Dr. Senthilvelan – Shoulder, Elbow & Wrist Specialist
Overhead throwing is one of the most demanding movements in sports. Whether you are a cricketer, volleyball player, tennis athlete, swimmer, or javelin thrower, repetitive high-velocity motion places enormous stress on the shoulder joint.
Over time, this can lead to pain, loss of performance, and structural injury. Early diagnosis and the right treatment approach can help athletes return safely to their sport.
Why the Throwing Shoulder Is Vulnerable
The shoulder is a highly mobile ball-and-socket joint made up of:
- Humerus (upper arm bone)
- Scapula (shoulder blade)
- Clavicle (collarbone)
Key stabilizing structures:
- Labrum – deepens the socket and stabilizes the joint
- Shoulder capsule & ligaments – prevent dislocation
- Rotator cuff muscles – dynamically control movement
- Scapular stabilizers – provide the foundation for overhead motion
In throwing athletes, extreme external rotation during the cocking phase and rapid deceleration during follow-through create repetitive micro-stress. Over time, this may lead to instability and tissue damage.
Common Shoulder Injuries in Throwing Athletes
1. SLAP Tear (Superior Labrum Tear)
A SLAP tear affects the top part of the labrum where the biceps tendon attaches.
Symptoms:
- Deep shoulder pain
- Catching or locking sensation
- Pain during overhead throwing
- Loss of throwing velocity
2. Biceps Tendinitis
Repetitive throwing can inflame the long head of the biceps tendon.
Symptoms:
- Pain in the front of the shoulder
- Weakness
- Occasionally a popping sensation
3. Rotator Cuff Injury
The rotator cuff is commonly affected in overhead athletes.
Early Signs:
- Shoulder pain while throwing
- Night pain
- Reduced strength
Untreated inflammation may progress to partial or full tendon tears.
4. Internal Impingement
During extreme rotation, rotator cuff tendons may get pinched between the humeral head and glenoid.
This condition is common in competitive throwers and may lead to partial cuff tears or labral damage.
5. Shoulder Instability (“Dead Arm Syndrome”)
During extreme rotation, rotator cuff tendons m
Chronic stretching of the capsule from repeated throwing may lead to subtle instability.
Athletes may notice:
- Sudden loss of power
- Arm fatigue
- Reduced accuracy
- Drop in performance
ay get pinched between the humeral head and glenoid.
This condition is common in competitive throwers and may lead to partial cuff tears or labral damage.
6. GIRD (Glenohumeral Internal Rotation Deficit)
Loss of internal rotation due to posterior shoulder tightness.
This significantly increases the risk of labral and rotator cuff injuries.
7. Scapular Dyskinesis (SICK Scapula)
Abnormal scapular positioning affects throwing mechanics.
Symptoms:
- Pain near the collarbone
- Shoulder drooping
- Weakness during overhead motion
Evaluation at Our Clinic
At Dr. Senthilvelan’s Shoulder & Elbow Clinic, evaluation includes:
- Detailed sports history
- Range of motion testing
- Stability assessment
- Strength evaluation
- Advanced imaging (if required):
- X-ray
- MRI
- MR arthrogram
- Ultrasound
Early diagnosis helps prevent progression to complex injuries.
Treatment Approach
Non-Surgical Management (First Line)
Most throwing injuries can be treated without surgery.
- Activity modification
- Ice therapy
- Anti-inflammatory medication
- Structured physiotherapy program:
- Posterior capsule stretching
- Rotator cuff strengthening
- Scapular stabilization
- Core conditioning
- Biomechanical correction of throwing technique
Cortisone injections may be used selectively in certain cases.
Arthroscopic Shoulder Surgery
If symptoms persist despite conservative treatment, minimally invasive arthroscopic surgery may be recommended.
Procedures include:
- SLAP repair
- Rotator cuff repair
- Capsular stabilization
- Debridement of damaged tissue
Rehabilitation Timeline:
- Sling protection (2–4 weeks)
- Gradual physiotherapy
- Strength phase at 4–6 weeks
- Return to throwing at 4–6 months
- Full competitive return may take up to 12 months
Prevention for Throwing Athletes
To reduce injury risk:
✔ Maintain flexibility
✔ Strengthen rotator cuff & scapular muscles
✔ Improve core stability
✔ Follow structured throwing programs
✔ Allow adequate recovery between sessions
