Mid-Term Efficacy of Surgical Treatment for Calcaneal Fracture Combined with Die-Punch Bone Block

To discuss the surgical efficacy and experience of calcaneal fracture combined with die-punch bone block. Open reduction and internal fixation for 27 patients (27 feet) with calcaneal fracture combined with die-punch bone block were performed, the die-punch bone blocks were untreated in earlier stage, calcaneal anatomical recovery and function were evaluated during follow-up in one year after surgery. The follow-up results for the 27 patients in one year after the surgeries show the postoperative width of intraoperative die-punch bone block treatment group was significantly better than that of non-treatment group (p<0.05), the postoperative functional scores of treatment group were superior to those of non-treatment group (p<0.05), and there were no significant differences in preoperative and postoperative calcaneal height, length, Bohler angle and Gissane angle between treatment group and non-treatment group (p>0.05). According to 100-point criteria of Tieliang Zhang, there were 1 excellent case, 2 good cases, 4 medium cases and 2 poor cases in non-treatment group, and there were 5 excellent cases, 10 good cases, 2 medium cases and 1 poor case in treatment group; the scores of the treatment group were better than those of the untreated group (p<0.05). For intra-articular calcaneal fractures combined with die-punch bone block, it is necessary to pay attention to the surgical anatomical reduction. The steps of articular surface should be controlled within 1mm. The treatment for calcaneal fracture combined with die-punch bone block must be performed by open reduction and internal fixation, and meanwhile the treatment for die-punch bone block should be emphasized, in order to reduce the occurrence of dysfunction during recovery
