Abstract
Introduction
The aim of systematic review and meta-analysis was to find out whether minimally invasive plate osteosynthesis (MIPO) is better than open reduction and internal plate fixation (ORIF) in terms of functional outcome, achieving union (union time and incidence of non-union), intraoperative parameters (surgical duration, blood loss, and radiation exposure), and complications (iatrogenic radial nerve palsy and infection) for humeral shaft fractures.
Materials and Methods
We searched online databases (Pubmed, Embase, Scopus, and The Cochrane Library) from inception till 3rd September 2020 for articles comparing MIPO with ORIF for humeral shaft fractures. The methodological quality of randomized controlled trials (RCTs) was done by Cochrane Risk of Bias assessment tool 2 (RoB2) and of non-randomized studies (case–control and cohort studies) by Methodological Index for non-randomized studies (MINORS). Meta-analysis was performed using Review Manager 5.4 software.
Results
11 studies (5 RCTs and 6 non-randomized comparative studies) involving a total of 582 patients (MIPO-290, ORIF-292) meeting our inclusion criteria were included in the study. There was no statistically significant difference in pooled analysis of functional outcome scores between MIPO and ORIF. Union time was significantly lesser (mean difference = 3.12 weeks) and incidence of non-union lower (odd’s ratio = 0.27) in MIPO group. Surgical duration and intraoperative blood loss were significantly lesser in MIPO group. Iatrogenic radial nerve palsy and infection were higher in ORIF group.
Conclusions
This study showed that MIPO gives similar functional outcomes as compared to ORIF but causes significantly lesser blood loss, requires lesser operative duration and has a lesser incidence of major complications.
