If the amount of bone displacement is great then it will need to be surgically repaired and pinned to avoid future complications. This fracture typically results in a dorsally and radially displaced metacarpal shaft relative to the well-anchored volar ulnar fragment. A CT scan is best for confirming the diagnosis. A Bennett fracture is a common injury that involves an intra-articular fracture at the base of the first metacarpal. However, it often accompanies Bennett’s fracture. It is a rare injury, occurring in less than 5% of carpal fractures. This is a break of the trapezius bone in the wrist. A Bennetts fracture usually occurs when there is a force applied upon a flexed metacarpal, such as punching a hard object or falling on an outstretched hand. Surgery will be required to ensure minimal or no long-term disability.Įxpert interview: Mr Elliot Sorene MBBS FRCS (Tr & Orth) EDHS Consultant Orthopaedic, Hand & Upper Limb Surgeon talks about surgery for Bennett’s Fracture.If you suspect a fracture of any bones in your hand then seek urgent medical attention immediately.In particular, problems, when bringing the thumb across the palm of the hand and pinching with the index or middle fingers are common if the fracture does not heal properly. It is similar to a Rolando fracture which is also a fracture to the base of the thumb, but with more serious fragmenting of bones.Ī Bennett fracture is a serious injury which if not treated correctly can cause permanent disability. With Bennett’s fracture, a small part of the metacarpal bone will remain attached to the volar ligament, whilst the main part of the bone is dislocated. This is known as the first carpometacarpal joint, where the carpal bone of the hand connects to the metacarpal bone of the thumb. It is a fracture and dislocation of the joint at the base of the thumb. In more serious cases the thumb may appear deformed.Ī Rolando fracture is also a fracture to the base of the 1st metacarpal where it joins the carpal bones between the thumb and the wrist, although a little more complex to treat as the metacarpal is fractured into several pieces.The patient will find it very difficult to move the wrist and thumb.There will be rapid swelling and bruising may develop.Immediate and severe pain over the thumb side of the wrist.Untreated or malreduced fractures can lead to post-traumatic osteoarthritis, which can cause significant pain and functional decline.Symptoms will be similar to other wrist and hand fractures: The treatment algorithm is also influenced by the age and profession/hobbies of the patient. While open reduction and internal fixation with a screw or K-wire are both common practice, screws are often preferred as K-wires must be removed after union. Bennett fracture is an intra-articular fracture of the base of the first metacarpal with resultant dislocation of the first carpometacarpal joint.1 It was. Operative treatment is recommended for unstable fracture patterns and intra-articular displacement of >1 mm. Non-operative treatment in a thumb spica cast for 3-4 weeks can be considered in stable, non-displaced fractures. When an intra-articular fracture of the 1 st metacarpal is comminuted, producing at least three parts, it is referred to as a Rolando fracture which has a worse prognosis. lateral retraction of the first metacarpal shaft by abductor pollicis longus.This is the American ICD-10-CM version of S62. small fragment of 1 st metacarpal, attached to anterior oblique ligament, continues to articulate with trapezium, Short description: Bennetts fracture, left hand, init encntr for open fracture The 2023 edition of ICD-10-CM S62.212B became effective on October 1, 2022.two piece fracture of the base of the thumb metacarpal.
