2

Proximal phalanx growth assessment

Regular clinical and radiographic evaluation of proximal phalanges in the hand to track epiphyseal development and identify need for intervention. Essential during periods of active skeletal growth.

monitoring
3

Hand grip and pinch strengthening

Progressive resistance exercises targeting grip strength and pinch mechanics to compensate for proximal phalanx abnormalities. Includes therapy putty, grip strengtheners, and functional task practice.

Additional treatment options

Corticosteroid injection therapy

Local injection of anti-inflammatory medication around affected proximal phalanges to reduce inflammation and pain. May provide temporary relief and facilitate participation in physical therapy.

procedure

Activity pacing and joint protection

Education on joint protection techniques including avoiding repetitive gripping, using both hands for heavy tasks, and pacing activities to prevent overuse of affected fingers.

lifestyle

Epiphysiodesis procedure

Surgical arrest of abnormal epiphyseal growth to prevent progressive deformity in affected proximal phalanges. Performed in growing children when growth modulation can correct the deformity.
