Abstract:

BACKGROUND: There are various open reduction internal fixation methods and materials, such as specific plate, type U fixation, quadruple-feet nails or tension band fixation. Due to the complex anatomic structures of calcaneus, how to select an internal material that both has good internal strength and can avoid long-term complications need to be explored. 
OBJECTIVE: To evaluate the clinical value of plastic titanic plate for intra-articular fracture of calcaneus and its biocompatibility.
METHODS: Plastic titanic plates were used in 30 cases (34 feet) with Sanders classificationⅡ-Ⅳ calcaneal fractures approached via lateral L and oblique incision. Autogenous iliac bone-grafting was used in all cases. Postoperative therapeutic effects were evaluated by X-ray film. Based on Maryland foot score, subjective pain assessment, functional recovery, and motion situations were observed. The healing conditions in two groups were compared. 
RESULTS AND CONCLUSION: Totally 26 cases were followed up for 9-18 months, compared with the preoperative group, Bohler angle and Gissane angle were significantly satisfactorily after operation (P < 0.001). According to Maryland foot scores, the excellent and good rate was 88.5%, and the oblique lateral incision can be considered as a good alterative of lateral approach for intra-articular fracture of calcaneus. The open reduction and internal fixation with plastic titanic plate is reliable to treat displaced intra-articular fracture of calcaneus. Effective preparation before operation, surgery familiarity of fracture of calcaneus and basic anatomic of calcaneus are the key factors of successful operation.
