Comparison between Minimally Invasive Plate Osteosynthesis and Conventional Open Plating for Midshaft Clavicle Fractures: A Systematic Review and Meta-Analysis

Abstract EN

Objective.

The aim of this study was to compare the functional outcome and complications in midshaft clavicle fractures receiving minimally invasive plate osteosynthesis and conventional open plating.

Methods.

Relevant studies were searched in the databases of Medline, EMBASE, Cochrane Library, Ovid, and Web of Science from inception to March 1, 2019.

Pooled data were analyzed with Cochrane Collaboration’s Review Manager 5.3.

Results.

A total of 7 studies were included, of which 2 were randomized controlled trials, 3 were retrospective cohort studies, and 2 were prospective cohort studies including 316 patients.

No statistical differences in functional outcome (weighted mean difference [WMD] = 0.99, P=0.12), operation time (WMD = −10.44, P=0.07) and time to bone union (WMD = −0.23, P=0.70) were observed between the two groups.

However, minimally invasive plate osteosynthesis reduced rates of skin numbness (odds ratio (OR) = 0.25, 95% CI : 0.13 to 0.48; P<0.0001) and complications (OR = 0.33, 95% CI : 0.16 to 0.71; P=0.005) compared with conventional open plating.

Conclusion.

This systematic review and meta-analysis found no differences in terms of functional outcomes, operation time, and fracture healing time between minimally invasive plate osteosynthesis and conventional open plating.

However, minimally invasive plate osteosynthesis had apparent advantages in rates of skin numbness and complications.
