Throwing injuries are a category of shoulder and elbow conditions that develop in overhead athletes from the repetitive high-velocity motion of throwing. These are not single injuries but rather a spectrum of pathology that can involve the rotator cuff, labrum, capsule, bone, and biceps tendon, often in combination. Dr. Chudik treats the full range of throwing injuries and adapts treatment to the specific pattern each athlete presents with.
What Are Throwing Injuries?
The throwing motion places the shoulder at the extremes of its range in a fraction of a second. In the late cocking phase, the arm abducts and externally rotates to near 180 degrees. In the acceleration phase, the shoulder internally rotates at an angular velocity approaching 7,000 degrees per second. In the follow-through phase, the deceleration forces eccentric load on the rotator cuff and posterior capsule.
Over years of training, this pattern produces predictable adaptations and injuries:
- Anterior capsular laxity from repeated cocking-position stretching
- Posterior capsule tightness (glenohumeral internal rotation deficit, or GIRD)
- Internal impingement of the rotator cuff undersurface against the posterior-superior glenoid
- Posterior-superior labral tears (Type II SLAP)
- Rotator cuff undersurface tears
- Little League shoulder in skeletally immature throwers
- Ulnar collateral ligament (UCL) injury at the elbow
- Biceps tendon pathology at the shoulder
These conditions often coexist, which is why evaluation and treatment of the thrower involves the whole chain from the shoulder to the elbow and back to the scapula and trunk.
Causes and Risk Factors
- High pitch counts, year-round throwing, and early sport specialization
- Inadequate rest and recovery between outings
- Throwing breaking pitches at young ages
- Poor throwing mechanics and deficient kinetic chain contribution (hip, core, scapula)
- Fatigue, which shifts load onto tissues that cannot tolerate it
- Prior throwing injury that was not fully rehabilitated
Symptoms
- Loss of velocity or command
- Pain in specific phases of the throwing motion (late cocking, acceleration, deceleration)
- Dead arm sensation during throwing
- Pain that resolves with rest and recurs with throwing
- Specific pain patterns depending on the structure involved: posterior shoulder for internal impingement, medial elbow for UCL, anterior shoulder for biceps or subscapularis
Diagnosis
Dr. Chudik’s evaluation of the thrower is detailed. It includes the sport, position, age, throwing volume, the specific pain pattern through the throwing motion, mechanical observations, and a physical examination that evaluates range of motion (with particular attention to GIRD), stability, rotator cuff strength, labral signs, scapular mechanics, and elbow stability. Imaging typically includes MRI arthrogram of the shoulder and often X-rays of the elbow. The Westmont office has on-site high-field MRI and X-ray.
Treatment
Most throwing injuries are managed non-surgically, particularly when addressed early. Treatment includes:
- Rest from throwing
- A targeted physical therapy program addressing GIRD, rotator cuff balance, scapular mechanics, and kinetic chain integration
- Mechanics review and correction
- A graduated return-to-throw program
- Evaluation of volume and rest patterns to prevent recurrence
Surgery is reserved for specific structural injuries (labral tears, rotator cuff tears, UCL tears) that fail non-surgical treatment or that are unlikely to heal without repair. Dr. Chudik performs arthroscopic labral repair, rotator cuff repair, and biceps tenodesis at the shoulder. UCL reconstruction (Tommy John surgery) addresses elbow ligament injuries.
Recovery and Outcomes
Non-surgical recovery for most throwing injuries takes three to six months from the start of rest to full return to competitive throwing, with the return-to-throw program occupying the last six to eight weeks.
Post-surgical recovery depends on the procedure. Labral repairs typically require six to nine months before return to competitive throwing. UCL reconstruction requires 12 to 18 months.
Return-to-throw outcomes depend on early recognition, adherence to rehabilitation, and attention to the mechanics and volume drivers that produced the injury. Recurrence is common in athletes who return to the same patterns that caused the original problem.
When to See Dr. Chudik
Schedule an evaluation if throwing has become painful, if velocity or command has dropped unexpectedly, or if prior treatment has not resolved symptoms. Early evaluation preserves treatment options. Call 630-324-0402 or request an appointment online.
