OBJECTIVE@#To summarize the complications of core drilling intramedullary nail in the treatment of femoral shaft closed fracture and explore the treatment strategy.@*METHODS@#From August 2014 to June 2018, a total of 215 patients with closed femoral shaft fractures were treated with closed reduction core drill intramedullary nail, including 129 males and 86 females, aged from 18 to 62 years, with an average of (44.2±10.6) years old. The time from injury to operation was 3 to 21 days. There were 102 cases of AO type A fracture, 82 cases of AO type B fracture and 31 cases of AO type C fracture. The time of operation, the amount of blood loss during operation, the duration of hospitalization, the time of fracture healing and the HSS score of knee joint function at the last follow-up were recorded. The observation of complications included:iatrogenic fracture, core drill broken, core drill twist, postoperative infection, and fracture nonunion.@*RESULTS@#The average operation time was (63.2± 15.6) min and intraoperative blood loss was (150.0±34.5) ml. All the incisions reached grade A healing. Patients were follow up for a mean of (18.5±3.2) months, the average hospital stay was (4.3±1.2) days, and the average fracture healing time was (5.6±2.3) months. At the final follow-up, the average HSS score of knee joint was 90.3±4.7. Related complications occurred in 37 cases (17.2%). The core drill related complications occurred in 13 cases (6.0%), including core drill broken in 5 cases (2.3%), core removal in 1 case and slotting in 4 cases;core drill twist in 8 cases (3.7%). After the core was cut, the core was removed. Similar complicationsof conventional intramedullary nail:iatrogenic fracture was performed in 12 cases (5.6%), including 10 cases of fracture end split and 2 cases of distal perimedullary fracture of intramedullary nail. The patients with cleavage at the fracture end were not treated after judging their stability, and the patients with fracture around the distal end of the intramedullary nail were fixed with auxiliary steel plate during operation;1 case(0.4%) with delayed infection after operation, debridement and external fixation was replaced and healed after bone transfer; fracture nonunion occurred in 11 cases (5.1%), of which 7 cases (3.3%) were hypertrophic nonunion and healed with additional plate. Atrophic nonunion occurred in 4 cases (1.9%), which healed after additional steel plate and bone graft.@*CONCLUSION@#Core drilling intramedullary nail is an effective method for the treatment of closed femoral shaft fracture, and the complications include core drill related complications and conventional intramedullary nail similar complications. Accurate preoperative evaluation, careful operation during operation and early postoperative symptomatic treatment can effectively reduce the occurrence of related complications.

Objective:To observe the effect of early weight-bearing on the appropriate population with intertrochanteric fracture after surgery. Methods:From April, 2017 to December, 2018, a total of 45 patients with Evans-Jensen type II intertrochanteric fracture and fracture reduction as positive medial cortex support (PMCS) after proximal femoral nail anti-rotation (PFNA) fixation were randomly divided into control group (n = 22) and experimental group (n = 23). Weight-bearing as tolerated (WBAT) was initiated from six weeks after surgery in the control group, and within 48 h after surgery in the experimental group. The frequency of WBAT in two groups increased gradually from three times a day for ten minutes a time to five times a day for 20 minutes a time until clinical healing of fracture. The length of stay, hospital cost, the fracture healing time and the complication incidence were compared between two groups, as well as the scores of Visual Analogue Scale (VAS) and Harris Hip Score at six weeks, three months and six months after surgery. Results:Compared with the control group, the length of stay was shorter (t = 3.716, P < 0.01), the hospital cost was lower, but no significant difference was found (t = 1.540, P > 0.05), and the fracture healing time was shorter (t = 6.248, P < 0.001) in the experimental group. The complication incidence was lower in the experimental group, but there was no significant difference (χ2= 2.198, P > 0.05). Six weeks, three months and six months after surgery, there was no significant difference in the score of VAS between two groups (t < 1.330, P > 0.05). The score of Harris Hip Score was significantly higher in the experimental group than in the control group six weeks after surgery (t = -5.115, P < 0.001), however, no significant difference was found in other time points (|t| < 1.799, P > 0.05). Conclusion:Early weight-bearing within 48 h after PFNA fixation for Evans-Jensen type II intertrochanteric fractures and reduction with PMCS could shorten the length of stay, shorten the bony healing time and promote early recovery of hip function.
