The Preliminary Study Of The Operative Time Of Intra-articular Calcaneal Fractures

Objective: To explore the necessity and the best time of the operative time of thethe intra-articular calcaneal fractures.Methods:53patients (58feet) with intra-articular calcaneal fracture werecollected dating from January2005to December2011. there were38males patients and15females patients. The Age of patient between18years and58years (average35.6years). According to Sanders classification: Ⅱ17cases (19feet), III in27cases (29foot), IV9cases (10feet). All the patients were accepted open reduction and steelplate Internal fixation. The operative time were within8hours after injury,within8h~for7days, different periods of7to14days after injury respectively.Recorded andcompared the preoperative and postoperative calcaneal height, width, Bohler’s anglerespectively,and postoperative recovery evaluation, postoperative complications andperioperative period indicators.Results: All patients were followed up for5to18months, an average of11months. Reexamination after the X-ray film showed the fracture healing, no looseningor fracture, the healing time is from8weeks to11weeks, with an average of8.2weeks. Six cases with skin flap necrosis and blisters and infection, the healing rate is11.53%. According to the Maryland scoring method: Group A (8h after injury)excellent rate was86.9%, Group B (8~7d) excellent rate was63.6%, Group C (7to14days) after the injury the excellent rate was87.5%. There were significantlydifferent in groups A, C and B on the curative effect (P <0.05). There were nosignificantly different in group A and group C (P>0.05). The incidence of earlypostoperative complications (x2test)in group A, group C and group B on postoperativecomplications are significant differences (P <0.05). There were no significantlydifferent in group A and group C (P>0.05).To measure the preoperative andpostoperative calcaneal height, width, Bohler’s angle Gissan’s angle, the measurement results were compared using paired t test, there were significant differences (P <0.05).Conclusion：Select the appropriate operative time can be a certain degree to avoidthe risk of postoperative wound healing problems. Within8h after injury, or7to14days of surgery, the incision can be more effectively avoid risks, reduce postoperativecomplications and good clinical efficacy.
