Physical Therapy Nest

Diagnosis of jersey finger typically involves:

• Medical history review (sports injury, sudden trauma to the finger).

• Physical exam:

  • Inability to flex the fingertip at the distal interphalangeal (DIP) joint.

  • Tenderness and swelling along the finger.

• Imaging:

  • X-rays may be ordered to check for associated fractures.

  • MRI or ultrasound can confirm tendon injury and location of retraction.

Jersey finger almost always requires surgical repair, followed by an extensive course of physical therapy. Therapy focuses on regaining mobility, strength, and hand function. Treatment may include:

• Post-surgical care with protective splinting or bracing

• Gentle range of motion exercises once cleared by the surgeon

• Manual therapy to reduce stiffness and scar tissue

• Strengthening exercises for finger flexion and grip strength

• Scar management to ensure tendon glide and prevent adhesions

• Functional retraining for fine motor skills and athletic movements

• Education on safe return to sports or daily activities

Common signs of jersey finger include:

• Sudden pain at the fingertip during injury

• Swelling and bruising along the finger

• Inability to bend the fingertip (DIP joint)

• Tenderness at the site of tendon injury

• Weakness in grip or inability to grasp objects properly

Because jersey finger is usually a traumatic injury, prevention is limited, but risks can be reduced by:

• Using proper grip techniques during sports

• Wearing protective gloves in contact sports when possible

• Strengthening finger flexors and hand muscles for better resilience

• Seeking immediate treatment after finger injuries to avoid complications
