- Abstract
Although many studies have investigated iatrogenic radial nerve palsy (RNP) in humerus shaft fracture, there is inconsistent evidence on which approach leads to iatrogenic RNP. Moreover, no meta-analysis has directly compared the anterolateral and posterior approaches regarding iatrogenic RNP. In this systematic review and meta-analysis, the MEDLINE, Embase, and Cochrane Library databases were searched systematically for studies published before March 30, 2021. We included studies that (1) assessed the RNP in the surgical treatment of humerus shaft fracture and (2) directly compared the anterolateral and posterior approaches regarding the RNP. We performed synthetic analyses of the incidence of iatrogenic RNP and the recovery rate of iatrogenic RNP in humerus shaft fracture between the anterolateral and posterior approaches. Our study enrolled nine studies, representing 1303 patients who underwent surgery for humerus shaft fracture. After exclusion of traumatic RNP, iatrogenic RNP was reported in 35 out of 678 patients in the anterolateral approach and in 69 out of 497 patients in the posterior approach. Pooled analysis revealed that the incidence of iatrogenic RNP was significantly higher in the posterior approach than in the anterolateral approach (OR = 2.72; 95% confidence interval (CI), 1.70–4.35; P < 0.0001, I2 = 0%), but there was no significant difference in the recovery rates of iatrogenic RNP between the two approaches (OR = 1.55; 95% CI, 0.26–9.18; P = 0.63, I2 = 0%). In this meta-analysis, the posterior approach showed a higher incidence of iatrogenic RNP than the anterolateral approach in the surgical treatment of humerus shaft fracture. With limited studies, it is difficult to anticipate if any particular approach favors the recovery of iatrogenic RNP.
