Metacarpal head fractures are rare intra-articular injuries that require anatomic fixation and may be underappreciated in children because of the complex geometry and largely cartilaginous nature of the metacarpal head. Metacarpal neck fractures account for three-fourths of all finger metacarpal fractures, and increasing acceptable alignment of the index finger through the little finger metacarpal necks (10°, 20°, 30°, and 40° across the digits, respectively) is commonly recommended. 11 fractures with minimal displacement had been immobilised in a plaster cast without reduction. Metacarpal shaft fractures can result from a simple bending moment however, they also can result from a rotational force, which may cause finger crossover that will not remodel and requires reduction. The treatment of 64 intra-articular fractures at the base of the fifth metacarpal was studied. Finger metacarpal base fractures, especially those in young children, are often the result of high-energ y injuries and should increase a physician's concern for compartment syndrome. Thumb metacarpal base fractures with lateral metaphyseal fragments and pediatric Bennett fracture variants (Salter-Harris type III and type IV fractures) are unstable and require surgical management. Thumb metacarpal base fractures that involve the physis warrant special attention. Pseudoepiphyses can be confused with metacarpal fractures however, a careful physical examination can help physicians distinguish the two. Overview What is a metacarpal fracture A metacarpal fracture is a type of bone fracture (broken bone). Understandably, fractures of the metacarpals disrupt this mechanism causing significant disability for the active or working patient and can come about from several different mechanisms. Fracture of neck of first metacarpal bone. The metacarpals form the osseous base of the complex lever system of flexor and extensor tendons of the hand. Fracture of shaft of first metacarpal bone. Other fracture of base of first metacarpal bone. Pediatric metacarpal fractures commonly occur in patients aged 13 to 16 years, with most injuries sustained during sports activities. ICD-10 code S62.2 for Fracture of first metacarpal bone is a medical classification as listed by WHO under the range -Injuries to the wrist, hand and. Metacarpal fractures account for 10% to 35% of all pediatric hand fractures.
