[Prefabricated curvature internal fixation with Kirschner needle for forearm fracture in children]

To explore clinical effect of precast curvature internal fixation with Kirschner needle in treating forearm fracture in children.

From October 2019 to December 2022,32 children with forearm fractures were treated with precast curvature internal fixation with Kirkler's needles,including 25 males and 7 females,aged from 3 to 15 years old with an average of (8.0±0.5) years old,18 patients on the left side and 14 on the right side,24 patients with double fractures of radial and ulna,3 patients with Monteggia fractures,and 4 patients with Galeazzi fractures,and 1 patient with radial neck fracture of crooked cap. Operation time,intraoperative blood loss,C-arm fluoroscopy,fracture healing time and complications were recorded,and disabilities of arm,shoulder and hand (DASH) scale and Grace-Eversman forearm double fracture evaluation system were used to evaluate clinical efficacy of precast curvature internal fixation with Kirschner's needle for forearm fracture in children.

All 32 patients were followed up for 2 to 12 months with an average of (7.16±2.51) months. Intraoperative blood loss was (20.68±5.50) ml,C-arm fluoroscopy was(5.80±2.50),and operation time was (24.34±5.10) min,fracture healing time was (8.82±1.62) weeks. Two patients occurred complications,including postoperative rupture of extensor pollicis longus tendon in 1 patient and obvious displacement of fracture caused by rotation of prefabricated curvature Kirschler needle on bone marrow cavity in 1 patient. DASH scores ranged from 0 to 16 scores with an average of (8.32±1.50) scores. According to Grace-Eversman double fracture evaluation system,28 patients got excellent result,2 good and 2 fair.

The treatment of forearm fracture with Kirschner's needle prefabricated curvature internal fixation has advantages of less trauma,less bleeding,good reduction,stable fixation,fast fracture healing and good functional recovery.
