Lastly, fractures at the wrist-end of the bone are called fractures of the base of the metacarpal. Open reduction and internal fixation (ORIF) is indicated for displaced intra-articular injuries.

Conservative treatment Conservative treatment used to be proposed [19], but recent studies reported poor results with closed reduction of thumb metacarpal fractures [20]. metacarpal bones. pal fractures occur in the thumb metacarpal, with 80% of those occurring at the base. Fractures at the base are known as Bennett fractures or Rolando fractures. If the fracture involves either the joint at the base of the thumb (the carpometacarpal joint) or the joint at where the thumb joins the proximal phalanx (the metacarpophalangeal joint), surgery may be required to repair the joint. It can be described as a Y- or T-shaped fracture line that runs longitudinally through the metaphyseal area, with an intra-articular fracture splitting the metacarpal base fragment into a volar and a dorsal fragment.

Many thumb metacarpal fractures do not require surgery. However, both conservative and operative management of fractures of the hand can result in stiffness. 1. A Rolando fracture is similar to a Bennett fracture but is a comminuted intra-articular fracture of the thumb metacarpal base and is a less common injury . The thumb CMC joint is vital to the function of the hand, and injuries can result in pain, weakness, and loss of grip or pinch strength.… We aimed to describe the treatment of comminuted fractures of the base of the thumb metacarpal using a cemented bone-K-wire frame. Metacarpal neck fractures are common. Bennet Fractures (Figure B) are oblique intra-articular fractures at the base of the thumb in which ligamentous insertion holds the fracture fragment while the metacarpal itself displaces. Gamekeeper's thumb, also known as skier's thumb or break-dancer's thumb is avulsion or rupture of the ulnar collateral ligament (UCL) of the first metacarpophalangeal joint. The Bennett fracture is the most common.1 Historically, the treatment of extra-articular fractures has occa-sioned little debate. There is a lack of strong evidence guiding the treatment of non-thumb isolated closed metacarpal shaft fractures towards operative fixation versus conservative management. Abstract: Fracture of the base of the thumb metacarpal (M1) is a common finding in hand trauma. Most metacarpal neck fractures are the result of striking a hard object with a fist, and the most commonly fractured digit is the small finger. He has a closed small finger metacarpal neck fracture with radiographs showing 45° of apex dorsal angulation. Each hand has five metacarpals, one for the thumb and each finger. If the fracture is open, meaning there is a . Pediatric variants include Salter-Harris type III and IV fractures . Fractures of the metacarpal bones account for 10% of all fractures and 40% of all hand fractures 1). flexion-extension motion.

Sometimes "buddy-taping" to the uninjured, neighboring finger can be used in stable fractures. As the name suggests, the "neck" is the area between the long shaft of the bone and the round knobby end (the "head") that helps form the joint. Proximal; Middle; Distal; Treatment General Fracture Management. Follow-up x-rays are obtained to see how the fracture is healing, and to evaluate for displacement.

Conservative treatment Conservative treatment used to be proposed [19], but recent studies reported poor results with closed reduction of thumb metacarpal fractures [20]. Most metacarpal fractures have a good outcome with nonoperative treatment because there is substantial tolerance to angulation and shortening, particularly fractures of the small finger metacarpal shaft and neck. Comparison of short-term outcomes and final fracture alignments. Christina Ward MD. Metacarpal fracture can be termed as broken hand. The treatment goals are to reposition the first metacarpal in the carpo-metacarpal joint, and to restore the articular surface. 2 Occasionally, if stiffness becomes a problem after cast treatment, a hand therapist will be recommended to work with you. With a neck fracture, the metacarpal head can poke out into the palm of . They can occur from a variety of injuries such as a fall, a motor vehicle collision, or punching a wall.
