Treatment - Metacarpal Shaft Fractures• Nonoperative

– Immobilization • indications

– nondisplaced metacarpal neck fractures– acceptable angulation (see above table)– no malrotation– shortening (aesthetic problem only)

• immobilize MCP joints in 70-90 degrees of flexion• Immobilization for 4 weeks

Finger Acceptable Shaft Angulation (degrees)

Acceptable Shaft Shortening (mm)

Index & Long Finger 10-20 2-5

Ring Finger 30 2-5

Little Finger 40 2-5

Page 14: Case conference Orthopedics I

Nonoperative treatment

• Reduction

Page 15: Case conference Orthopedics I

• Technique–Option 1: Immobilization with palmar splint

–Option 2: Immobilization with a forearm cast and finger splint

–Option 3: Attelle fonctionelle (Functional cast)

–Option 4: Ulnar Gutter Splinting

Page 16: Case conference Orthopedics I

Operative treatment

• indications– open fractures

– unacceptable angulation (see table)

– any malrotation

– multiple fractures

Finger Acceptable Shaft Angulation (degrees)

Acceptable Shaft Shortening (mm)

Index & Long Finger 10-20 2-5

Ring Finger 30 2-5

Little Finger 40 2-5

Page 17: Case conference Orthopedics I

Techniques of Operation

• closed reduction percutaneous pinning

• open reductions with lag screw– can use multiple lag screws for long spiral fractures

• try to get at least two lag screws

• open reduction with dorsal plating– works best for transverse fractures

– try to cover plate with periosteum to prevent tendon irritation

– begin early motion to prevent tendon irritations
