Abstract：Objective To explore the effect of calcaneal Z osteotomy in treatment of lfexible lfatfoot.Methods Retrospective analysis was conducted for 18 patients with lfexible lfatfoot treated with calcaneal Z osteotomy in Ruijin Hospital from October 2011 to December 2014. We measured the hindfoot valgus angles, talar decline angles and talar-ifrst metatarsal angles on lateral iflms and so on to compare the condition after surgery and before surgery. The AOFAS-AH score was adopted to evaluate the preoperative and postoperative status.Results All patients were followed up for an average of 17.6 months ( range, 12 to 28 months ). The preoperative hindfoot valgus angle, talar coverage angle, talo-first metatarsal angle in lateral view, talar decline angle and AOFAS-AH score were ( 12.9 ± 5.5 ) °, ( 24.4 ± 11.0 ) °, ( 17.1 ± 6.4 ) °, ( 32.4 ± 5.7 ) ° and ( 58.2 ± 17.5 ). The postoperative hindfoot valgus angle, , talar coverage angle, talo-ifrst metatarsal angle in lateral view, talar decline angle and AOFAS-AH scores were ( 2.0 ± 2.8 ) °, ( 11.3 ± 8.8 ) °, ( 3.3 ± 3.6 ) °, ( 23.0 ± 3.7 ) ° and ( 95.0 ± 4.4 ). The differences were statistically sigifnicant (P= 0.0002 ). Conclusions Calcaneal Z osteotomy is a sound method to deal with the lfexible lfatfoot. The procedure can relieve pain of patients and get normal alignment of foot. But it is worthy of further study because of insuifcient practice.
