Abstrakt: | This meta-analysis demonstrated that a greater prevalence of delayed union and nonunion and a longer time to fracture healing in the group that did not receive TPTD treatment after AFFs than in the group that received TPTD treatment. Purpose: To date, there is no hard evidence for medical management after atypical femoral fracture (AFF), even though weak data indicate faster healing with teriparatide (TPTD). Herein, we aimed to investigate the effect of postfracture TPTD treatment on AFF healing using a pairwise meta-analysis focusing on delayed union, nonunion, and fracture healing time. Methods: A systematic search of the MEDLINE (PUBMED), Embase, and Cochrane Library databases was performed for studies investigating the effect of TPTD after AFF up to October 11, 2022. We compared the incidence of delayed union and nonunion and the time of fracture healing between the TPTD ( +) and TPTD (-) groups. Results: The 6 studies analyzed a total of 214 AFF patients, including 93 who received TPTD therapy after AFF and 121 who did not. The pooled analysis showed a significantly higher rate of delayed union in the TPTD (-) group than in the TPTD ( +) group (OR, 0.24; 95% CI, 0.11-0.52; P < 0.01; I 2 = 0%), and a higher nonunion rate was observed in the TPTD (-) group than in the TPTD ( +) group with low heterogeneity (OR, 0.21; 95% CI, 0.06-0.78; P = 0.02; I 2 = 0%). The TPTD (-) group required 1.69 months longer to achieve fracture union than the TPTD ( +) group, with statistical significance (MD = - 1.69, 95% CI: - 2.44 to - 0.95, P < 0.01; I 2 = 13%). Subgroup analysis for patients with complete AFF showed that the TPTD (-) group had a higher rate of delayed union with low heterogeneity (OR, 0.22; 95% CI, 0.10-0.51; P < 0.01; I 2 = 0%), but there was no significant difference in the nonunion rate between TPTD ( +) and TPTD (-) groups (OR, 0.35; 95% CI, 0.06-2.21; P = 0.25; I 2 = 0%). Fracture healing took significantly longer in the TPTD (-) group (MD = - 1.81, 95% CI: - 2.55 to - 1.08; P < 0.01; I 2 = 48%). The reoperation rate showed no significant difference between the two groups (OR, 0.29; 95% CI, 0.07-1.20; P = 0.09; I 2 = 0%). Conclusions: The current meta-analysis supported the hypothesis that TPTD treatment following AFF might benefit fracture healing, lowering the rate of delayed union and nonunion and shortening the fracture healing time.
