Deformity that most often results from an injury to the tendons in back of the finger that are responsible for straightening the middle joint of the finger. May also be caused by Rheumatoid Arthritis.
Commonly sees finger swelling with the middle joint of the injured finger not able to straighten and the fingertip bending back. Deformity may develop immediately or may develop up to three weeks later. Unless promptly treated the deformity may progress resulting in permanent deformity and impaired function.
Deformity must be treated early to help retain full range of motion in the finger.
Nonsurgical: Preferred treatment includes splint for up to six weeks to straighten middle finger and allow the fingertip to bend. In the longer term exercises to improve strength and flexibility in the fingers and a protective splint for participation in sports to prevent re-injury are advised. If the deformity is caused by arthritis then medications and steroid injections are used along with splinting.
Surgery: Surgery is an option in certain cases where the tendon is severed, there is bone displacement, rheumatoid arthritis causes or the condition does not improve with splinting. Surgery may not be able to fully correct the condition but will reduce pain and improve functioning.
A splint is applied during recovery in conjunction with rehabilitation therapy which can take four to six months.
