Abstract:

BACKGROUND: In the treatment of radial head fractures, complications such as nonunion and internal fixation are inevitable in open reduction and internal fixation, resulting in chronic pain and dysfunction of the elbow joint. In order to reduce surgical complications and improve the success rate of surgery, radial head replacement surgery came into being.

OBJECTIVE: To systematically compare the effects of radial head arthroplasty and open reduction and internal fixation in the treatment of Mason type III and IV radial head fractures by meta-analysis.

METHODS: The search included clinical controlled studies published at home and abroad between 1999 and March 2019, with or without randomization and blinding. The databases included Embase, PubMed, Central, Cinahl, PQDT, CNKI, VIP, WanFang, Cochrane Library, and CBM. Magazine contents and references were manually retrieved to find grey references such as unpublished academic papers, and chapters in monographs. The language was not limited. All relevant articles were searched. If necessary, the articles were translated. The forearm rotation motion, forearm flexion mobility, postoperative joint function score, postoperative imaging evaluation results, postoperative complications and reversion cases were used as measurement outcomes so as to sufficiently compare the curative effects of arthroplasty and open reduction and internal fixation for treating Mason III type and IV of radial capitulum fracture.

RESULTS AND CONCLUSION: (1) According to the above search strategy, 301 related articles were retrieved. (2) By reading the title and abstract, 146 irrelevant articles were excluded, and 155 related articles were screened initially. The full text was further read and screened strictly according to the inclusion criteria and exclusion criteria, and finally seven foreign articles were included. (3) In the Beoberg-Morrey scoring system [95%CI (7.96, 23.14), P < 0.000 1], flexion and extension range [95%CI (3.72, 13.13), P=0.000 4], forearm pronation activity [95%CI (2.09, 3.18), P < 0.000 01], rotation range of motion [95%CI (2.80, 17.45), P=0.007], radial head arthroplasty was superior to open reduction and internal fixation. The number of postoperative complications in the radial head arthroplasty was less than that in the open reduction and internal fixation group [95%CI (0.15, 0.57), P=0.000 3]. (4) In summary, in the treatment of Mason type III and IV radial head fractures, radial head arthroplasty is superior to open reduction and internal fixation.
