Abstract：
UNASSIGNED: To explore the effectiveness of interlocking intramedullary nail fixation system for Sanders type Ⅱ and Ⅲ calcaneal fractures by comparing with open surgery.
UNASSIGNED: Forty patients (40 feet) with Sanders type Ⅱ and Ⅲ calcaneal fractures, who were admitted between May 2020 and December 2022 and met the selection criteria, were included in the study. They were randomly allocated into control group and minimally invasive group using a random number table method, with 20 cases in each group. The patients were treated with the interlocking intramedullary nail fixation system in the minimally invasive group and with steel plate internal fixation via a lateral L-shaped incision in the control group. There was no significant difference between the two groups ( P>0.05) in terms of gender, age, fracture classification and side, cause of injury, time from injury to admission, and preoperative width, length, height, Böhler angle, and Gissane angle of the calcaneus. The operation time, intraoperative blood loss, incision length, hospital stay, fracture healing time, incidence of complications, as well as pre- and post-operative imaging indicators (Böhler angle, Gissane angle, width, height, and length of the calcaneus) and American Orthopaedic Foot and Ankle Society (AOFAS) score of foot were recorded and compared between the two groups.
UNASSIGNED: The incision length, operation time, and hospital stay of the minimally invasive group were significantly shorter than those of the control group, and the intraoperative blood loss significantly reduced ( P<0.05). All patients of the two groups were followed up, with the follow-up time of 8-12 months (mean, 10.2 months) in the minimally invasive group and 8-12 months (mean, 10.4 months) in the control group. No complication occurred in the minimally invasive group after operation. One case of incision epidermal necrosis and 1 case of traumatic arthritis occurred in the control group after operation. However, there was no significant difference in the incidence of complications between the two groups ( P>0.05). At last follow-up, the AOFAS score was significantly higher in the minimally invasive group than in the control group ( P<0.05). Imaging examination showed that the calcaneal fractures of the two groups healed, and there was no significant difference in healing time between the two groups ( P>0.05). Compared with preoperative conditions, the Böhler angle and Gissane angle of the calcaneus in the two groups significantly increased, the width narrowed, and the height and length increased at 3 days after operation and the last follow-up, with significant differences ( P<0.05). There was no significant difference between 3 days after operation and last follow-up ( P>0.05). There was no significant difference between the two groups at each time point ( P>0.05).
UNASSIGNED: The interlocking intramedullary nail fixation system in treatment of Sanders type Ⅱ and Ⅲ calcaneal fractures has the advantages of minimal trauma, shortened hospital stay, reliable fracture reduction and fixation, and satisfactory foot function recovery.
UNASSIGNED: 通过与开放手术比较，探讨使用跟骨交锁髓内钉内固定系统治疗Sanders Ⅱ、Ⅲ型跟骨骨折的疗效。.
UNASSIGNED: 将2020年5月—2022年12月收治且符合选择标准的40例（40足）SandersⅡ、Ⅲ型跟骨骨折患者纳入研究，采用随机数字表法分为常规组及微创组，每组20例。微创组患者采用跟骨交锁髓内钉内固定系统治疗，常规组采用外侧L形切口联合钢板内固定治疗。两组患者性别、年龄、骨折分型及侧别、致伤原因、受伤至入院时间以及术前跟骨宽度、长度、高度、Böhler角、Gissane角等基线资料比较，差异均无统计学意义（ P>0.05）。比较两组手术时间、术中出血量、切口长度、住院时间、骨折愈合时间、并发症发生情况，以及手术前后影像学指标（跟骨Böhler角、Gissane角、宽度、高度及长度）、美国矫形足踝外科协会（AOFAS）评分。.
UNASSIGNED: 与常规组比较，微创组切口长度、手术时间及住院时间均缩短，术中出血量减少，差异均有统计学意义（ P<0.05）。两组患者均获随访，其中微创组随访时间8～12个月，平均10.2个月；常规组8～12个月，平均10.4个月。微创组术后无并发症发生；常规组术后发生切口表皮坏死1例、创伤性关节炎1例；但两组并发症发生率比较，差异无统计学意义（ P>0.05）。末次随访时，微创组AOFAS评分高于常规组（ P<0.05）。影像学复查示，两组跟骨骨折均愈合，且愈合时间差异无统计学意义（ P>0.05）。与术前相比，两组患者术后3 d及末次随访时跟骨Böhler角、Gissane角变大，宽度变窄，高度及长度增大，差异有统计学意义（ P<0.05）；末次随访时影像学评价指标与术后3 d比较，差异均无统计学意义（ P>0.05）。各时间点两组间影像学评价指标差异亦无统计学意义（ P>0.05）。.
