Diagnosis > Sports Injuries > Throwing Injuries

Throwing injuries occur in throwing sports, such as cricket, baseball, softball, water polo, javelin and American football (quarterbacks). These injuries are typically due to overuse, presenting gradually overtime and are often associated with poor throwing technique. Throwing injuries tend to occur in the upper limb of the throwing arm, with pain most commonly occurring in the shoulder or elbow.

Most Common Throwing Injuries


Rotator Cuff Tear

Tearing of one or more rotator cuff muscles or their respective tendons (figure 1), typically following a forceful throw or a fall onto the shoulder or outstretched arm. Associated with pain in the shoulder that may radiate into the upper arm and sometimes pain on firmly touching the affected rotator cuff muscle or tendon (figure 1). Pain may also increase during throwing, lifting activities (especially with the arm outstretched or above the head), certain other shoulder movements (often overhead activities), when weight bearing through the affected arm or when lying on the affected side.

SLAP Lesion

Damage to the cartilage lining the shoulder joint (labrum – figure 2) sometimes following overuse (such as excessive throwing), but often in association with a dislocated shoulder, a fall onto the arm or following a forceful throw. Pain is usually deep, although may present as vague shoulder pain. A clicking or catching sensation is often present during certain movements. Symptoms may increase with certain, often very specific movements or activities using the shoulder, such as cocking, acceleration or the release phase of throwing, during arm elevation or lifting (especially overhead), weight bearing through the affected arm (e.g. push ups) or sometimes lying on the affected side.

Medial Collateral Ligament Sprain

Tearing of the medial collateral ligament of the elbow (figure 3) typically following an excessive or repetitive sideways force to the elbow (valgus force – figure 4), such as throwing (particularly with poor technique). Associated with pain on firmly touching the affected ligament (at the inner aspect of the elbow) and often swelling. A snap or tear may be audible during injury.

Upper Back & Chest

Stress Fracture of the 1st Rib

Stress fracture of the first rib bone typically due to overuse associated with excessive muscle traction on the ribs during activities such as throwing. Typically associated with a dull ache in the shoulder, upper back, chest or lower neck (often near the collar bone) and tenderness on firmly touching the localised area of bone. Pain is usually worse with activity (e.g. throwing) and eases with rest.

Contributing Factors to Throwing Injuries Contributing Factors to Throwing Injuries

A number of factors may contribute to the development of throwing injuries, including:

  • Overuse (excessive or inappropriate training, i.e. throwing too often or for too long)
  • Poor throwing biomechanics (i.e. poor technique)
  • Inadequate upper limb and shoulder flexibility (particularly shoulder flexion, abduction, external or internal rotation)
  • Muscle tightness (particularly the latissimus dorsi, pectorals, rotator cuff, abdominals & hip flexors)
  • Inadequate thoracic spine flexibility (particularly into extension and rotation)
  • Joint stiffness (particularly the shoulder, elbow, upper back, lower back and hips)

Injury Prevention Tips for Throwing Athletes Injury Prevention Tips for Throwing Athletes

Correct Throwing Technique

Ensure your throwing technique is safe and efficient, minimising the risk of injury to the shoulder and elbow. Make sure you use the whole body, including the legs and hips rather than confining the throwing motion to the upper body.

Warm Up the Shoulder

One of the best ways to prevent throwing related shoulder injuries is with an effective warm up before sport. Shoulder exercises using resistance band helps activate the important stabilizing muscles, such as the rotator cuff and scapular stabilizers, and helps improve proprioception in preparation for throwing (see Upper Limb Resistance Band Exercises). Once you start throwing, ease into it. Avoid going straight into hard and fast or long throws. Gradually increase the distance and speed of the throws to allow your shoulder and elbow to warm up.


Ensuring adequate flexibility is important to improve your throwing technique and thus reduce the risk of injury. Key joints which require adequate range of motion for throwing include:

  • Shoulder
  • Elbow
  • Upper Back
  • Lower Back
  • Hips

Flexibility exercises for these body parts, and the muscles surrounding them, are an important aspect of injury prevention for throwers. Massage Therapy to these areas can also play a key role in maintaining adequate range of movement (see Upper Body and Lower Body Massage Ball Exercises).

Upper back (thoracic) flexibility (particularly extension and rotation) is extremely important for throwing athletes. Not only does this help with injury prevention to the shoulder, but it also assists in enhanced throwing performance. Exercises using a foam roller can help improve upper back flexibility (see Upper Back Flexibility Exercises).

Core Stability & Conditioning

In land based throwing sports, a stable pelvis, trunk and shoulder blade are essential to minimize stress on the shoulder and elbow, and, to improve throwing performance. Many throwing injuries can be attributed to poor strength or activation of the core stabilisers, such as the gluteals, scapular stabilisers, rotator cuff, transverses abdominis, obliques, multifidus and pelvic floor. As part of your training, ensure you spend enough time working on improving your gluteal strength, core stability, rotator cuff strength and scapular stability (see Core Stability Exercises, Pilates Exercises, Rotator Cuff Exercises, Gluteal Strengthening Exercises, and Scapular Stability Exercises).
