The proximal phalanx is one of the three bones that make up your finger. It is the first bone in your finger after your palm. Fractures of this bone are particularly common in children and we treat lots of them in the clinic.

Common causes, signs & symptoms of injury

A proximal phalanx fracture often occurs during contact sports, from a ball hitting the finger or a collision with another player. A fall or an accident, such as getting the finger caught in something, can also cause this injury.

Signs & symptoms to look out for are swelling and tenderness at the base of the finger. There may also be bruising in the area. An x-ray is required to diagnose the fracture.

Common treatments

A fracture that is non-displaced or minimally displaced can usually be treated conservatively. Your hand therapist can fabricate a custom-made thermoplastic splint to immobilise the fingers and allow for appropriate healing.

Here are some photos of a splint for a ring finger proximal phalanx fracture.

If the bone is fractured in a way that there are many pieces or the bone is displaced, this may require an appointment with a surgeon. Your hand therapist can also discuss this with you.

Exercises and recovery

Range of motion exercises are included as part of the recovery process. These are usually finger flexion and extension exercises. It is important to complete your exercises within a pain-free range. Exercises should be completed regularly throughout the day and light use of the hand can also aid in recovery.

Your hand therapist can create an exercise program that is tailored to your injury and difficulties. If you have broken your finger, please don’t hesitate to book an appointment. We’d be more than happy to help.
