Boxer's Fracture

A boxer’s fracture is a break in the 5th metacarpal bone of the hand, located just below the pinky finger. It usually happens from a direct impact with a closed fist, such as punching a hard object, but can also occur from accidental trauma like falls. While often stable, boxer’s fractures can cause significant pain, swelling, and reduced grip strength. Proper rehabilitation is essential to regain hand function and prevent long-term stiffness or deformity.
Diagnosis of Boxer's Fracture
Diagnosis typically includes:
-
Medical history review (mechanism of injury, type of impact).
-
Physical exam to check for tenderness, swelling, or knuckle deformity.
-
Imaging:
-
X-rays to confirm the fracture and measure angulation.
-
CT or MRI is rarely needed unless complications are suspected.
-
Treatment for Boxer's Fracture
Most boxer’s fractures heal with immobilization, but physical therapy is vital after casting or splinting. Therapy may include:
-
Edema control with compression, elevation, and massage
-
Manual therapy to restore mobility in the hand and fingers
-
Range of motion exercises for the fingers and wrist to prevent stiffness
-
Strengthening exercises for grip, pinch, and forearm muscles
-
Scar management if surgery is performed for severe displacement
-
Functional retraining to restore daily activities and fine motor skills
-
Education on protecting the hand and avoiding reinjury
Symptoms of Boxer's Fracture
Common signs of a boxer’s fracture include:
-
Pain and swelling on the pinky side of the hand
-
Bruising and tenderness around the knuckle
-
Reduced grip strength
-
Inability to fully straighten the pinky finger
-
Visible knuckle deformity or depressed knuckle appearance
-
Stiffness and weakness if left untreated
Prevention of Boxer's Fracture
To reduce the risk of boxer’s fractures and complications:
-
Use proper technique and protective gear during contact sports or martial arts
-
Avoid punching hard objects with a closed fist
-
Strengthen hand and forearm muscles for better support
-
Practice safe falls to reduce hand trauma
-
Address hand pain early to prevent worsening damage
