Replantation of the interphalangeal joint with reserving joint in children

Objective To discuss the treatment method and clinical efficacy of replantation of the interphalangeal joint with non-section osteotomy and reserving joint in children. Methods From January 2008 to January 2016, 19 children with completely severed interphalangeal joint were treated with distal middle 1/3 plane osteotomy shortening 0.3 to 0.5 cm, and the injured interphalangeal joints were reserved and replanted. Results All the replanted fingers survived uneventfully. The follow-up time ranged from 6 to 36 months with an average of 17 months. According to the upper extremity function evaluation criteria issued by Hand Surgery Society of the Chinese Medical Association, the results were graded as excellent in 14 cases, good in 4 cases and poor in 1 case. The replanted fingers were well developed with good interphalangeal joint motion. X-ray showed that the articular surface was intact without obvious degeneration. Conclusion For the children with completely severed interphalangeal joint, the replantation of interphalangeal joint with osteotomy and shortening of the proximal phalanx can reserve joint and epiphysis. The joint flexibility is restored and the normal development of the injured finger is observed. Key words: Replantation; Child; Osteotomy; Reserve joint
