Abstract

OBJECTIVE: The main purpose of this study was toevaluate the relationship between indications andcomplications of implant removal surgery.MATERIAL AND METHODS: The data of patients whounderwent implant removal surgery between 2011 and2014 were evaluated from our medical records. Patients’age, gender, anatomical site of implant and the type ofthe implant were evaluated. The interval between thefracture treatment and implant removal were recorded forall patients. The indications for implant removal surgerywere analyzed and their relationships with complicationswere evaluated by Pearson Chi-Square test.RESULTS: 276 patients (116 female, 160 male) with themean age of 36.2 ± 18.4 (range, 5 to 79 years) years underwentremoval of 279 implants. The mean interval frominitial operation to implant removal operation 27.9 ± 33months (range, 0.25 to 240 months). The most commonanatomical sites of implants were tibia in 93 patients (33.6%), femur in 63 patients (22.8 %) and fibula in 39 patients(14.1 %). Implant removal was indicated for implant failurein 54 patients (20%), for deep infection in 21 patients(8%), for implant irritation in 167 patients (60%), for pseudoarthrosisin 9 patients (3%), for only patient’s demandin 44 patients (16%) and for only surgeon’s demand in40 patients (14%). Overall complication rate was 17%.There was a significant correlation between the implantremoval due to infection and postoperative refractureand infection (r=0.101 p<0.001 and r=0.273 p<0.001, respectively).Significant correlation was obtained betweenimplant removal due to implant failure and pseudoarthrosisand the need of new implant as expected (r=0.375p<0.001 and r=0.639 p<0.001, respectively).CONCLUSIONS: Complications related to implantremoval surgery has a relationship with implant removalindications such as infection, pseudoarthrosis, andimplant failure.
