Mechanism of injury
- Distal phalanx tuft fractures are caused by crush injuries and often involve injury to the nail bed and nail plate.
- Avulsion fractures such as mallet finger and volar plate injuries are caused by hyperflexion or hyperextension of the finger.
- Phalangeal and metacarpal fractures are caused by direct trauma or rotational forces.
- Thumb ulnar collateral ligament injury (Gamekeeper’s thumb) is caused by hyper-abduction of the thumb.
Examination
- Compare both hands and look for bruising, erythema, swelling and deformity.
- Palpate for obvious areas of tenderness.
- Passive and active range of movement of all joints in hand and wrist should be examined. Testing against resistance may identify ligamentous injury.
- Assess for rotational deformity by asking the patient to make a fist. Look for “scissoring” or crossing over of the fingers.
- Assess for ulnar collateral ligament injury (Gamekeeper’s Thumb) by palpating for tenderness on the ulnar side at the base of the proximal phalanx and looking for pain / laxity on abduction of the thumb.
- Test sensation and motor function of the median, radial, and ulnar nerves.
Imaging
- Request a finger X-ray if the injury is localised to one digit. This should have PA, oblique, and lateral views and include the metacarpal and carpometacarpal joint.
- A hand X-ray should have PA, oblique, and fan lateral views and will include all bones of the hand, carpus, and distal radio-ulnar joint.
Specific management
Complicated Hand and Finger Fractures
Refer any complicated fractures to the Plastic Surgery team.
- Open fractures
- Amputations
- Associated tendon injury
- Neurovascular compromise.
Resting Volar Slab
The resting volar slab can be used to immobilise most acute hand fractures. It is a position of safe immobilisation with minimal strain on hand ligaments.
- Plaster backslab on volar (palmar) aspect of hand and forearm.
- Wrist in 30º extension.
- Metacarpophalangeal (MCP) joints flexed to 60º – 90º.
- Inter-phalangeal (IP) joints at 180º (fingers fully extended).
Distal Phalanx Tuft Fractures
![Distal tuft fractures](/~/media/Images/Hospitals/PCH/Page-Images/Health-professionals/ED-Guidelines/Fractures/Hand/Tuft-140x150.jpg)
- Simple tuft fractures are managed with buddy strapping or aluminium splint with GP follow up.
- If associated pulp laceration, antibiotics may be required.
- If associated nail bed injury, refer to Plastic Surgery.
Mallet finger

Volar plate injury
![A volar plate injury](/~/media/Images/Hospitals/PCH/Page-Images/Health-professionals/ED-Guidelines/Fractures/Hand/Volar-plate-150x150.jpg)
- Dorsal blocking splint and follow up with plastic surgery clinic in 1-2 days
Other phalangeal fractures
![Undisplaced stable shaft fracture](/~/media/Images/Hospitals/PCH/Page-Images/Health-professionals/ED-Guidelines/Fractures/Hand/Middle-phalanx-SH2-150x150.jpg?h=346&w=150&hash=484E94F36DE46F47A94445A6319983C0)
Undisplaced extra-articular fractures with NO rotational deformity
- Buddy strap and resting volar slab with follow up in Plastic Surgery clinic in 1-2 days.
Displaced, angulated, intra-articular fractures or rotational deformity
- Reduce fracture under ring block +/- sedation if appropriate. Otherwise refer to the Plastic Surgery team.
- Buddy strap and resting volar slab with follow up in Plastic Surgery clinic in 1-2 days.
Finger amputations
![Partial amputation](/~/media/Images/Hospitals/PCH/Page-Images/Health-professionals/ED-Guidelines/Fractures/Hand/Partial-amputation-150x150.jpg?h=154&w=200&hash=F270A273BC4245EFD6036BBFCAAAC205)
- All finger amputations should be referred urgently to Plastic Surgery.
- Irrigate stump with sodium chloride 0.9% and cover with sodium chloride 0.9% soaked gauze.
- Irrigate amputated part with sodium chloride 0.9%, wrap in sodium chloride 0.9% soaked gauze, place in a watertight plastic bag, and place the closed bag in an ice slurry.
- Treat as an open fracture (nil by mouth, intravenous antibiotics, tetanus booster if required).
Metacarpal fractures (2nd to 5th)
![Undisplaced stable fractures of neck or shaft (2nd-5th metacarpal)](/~/media/Images/Hospitals/PCH/Page-Images/Health-professionals/ED-Guidelines/Fractures/Hand/Metacarpal-150x150.jpg)
Undisplaced extra-articular fractures with NO rotational deformity
- Resting volar slab and follow up with Plastic Surgery clinic in 1-2 days.
![Plastic deformity of radius and ulna with volar tilt](/~/media/Images/Hospitals/PCH/Page-Images/Health-professionals/ED-Guidelines/Fractures/Hand/5th-metacarpal-150x150.jpg)
Displaced, angulated, intra-articular fractures or rotational deformity
- Most common is 5th "Boxer's Fracture".
- Reduce fracture under nerve block +/- sedation if appropriate. Otherwise refer to Plastic Surgery team.
- Resting volar slab and follow up with Plastic Surgery clinic in 1-2 days.
