Objective To evaluate the effectiveness of reamed versus nonreamed intramedullary nailing for femoral fractures. Methods Randomized controlled trials (RCTs) and clinical controlled trials (CCTs) were identified from MEDLINE (1966-2004.5), EMBASE (1966-2004.5), Cochrane Library (Issue 2, 2004), Cochrane Musculoskeletal Injuries Group Database (2004.5), and CBM disc (1979-2004.5). We handsearched Chinese Journal of Orthopaedy (from establishment to May 2004) and Orthopaedic Journal of China (from establishment to May 2004) . RCTs and CCTs were included. Data were extracted by two reviewers with designed extraction form. RevMan 4.2.3 software was used for data analysis. Results Five RCTs and two CCTs were included. The combined results of meta-analysis showed that reamed intramedullary nailing for femoral fractures can reduce the rate of nonunion (RR=0.38, 95%CI 0.17 to 0.83, P=0.01) and the rate of implant failure (RR=0.42, 95%CI 0.20 to 0.89, P=0.02). Conclusions Compared with nonreamed intramedullary nailing for femoral fractures, reamed intramedullary nailing can reduce the rates of nonunion and implant failure. However, the relation between reaming or pulmonary complications, the time of union, infection, malunion, operative time, and blood loss needs further study.
Objective To explore the clinical effect and complications of lumbar plexus block through different approaches on perioperative analgesia in aged proximal femur surgery, and find the best method for analgesia in these patients. Methods From January to December 2015, 150 elderly patients scheduled for proximal femur surgery were randomly divided into three groups: psoas compartment block (PCB group, n=50), Winnie " 3 in 1” block (Winnie group, n=50), and fascia iliaca compartment block (FICB group, n=50). Twelve hours before surgery, guided by ultrasound and nerve stimulator, lumbar plexus blocks were performed in all the patients, then patient-controlled analgesia (the formula and the usage were the same) was done. All patients received epidural anesthesia, and were maintained postoperative analgesia for 72 hours. If Rest Visual Analogue Scale>3 or Initiative Movement Visual Analogue Scale>4, sufentanyl 10 μgi.m. was given. Muscle strength grades and complications were recorded. Anesthetic effect of sensory block of femoral, lateral femoral cutaneous, and obturator nerves were measured and recorded too. Results There were two cases of epidural block, and one case of puncture point bleeding in group PCB; no complication in the other groups was found. There was no remedy for inadequate analgesia in the three groups. Compared with group PCB, the muscle strength grades during postoperative 24–72 hours in group FICB were higher (P<0.05). The successful rate of the block of lateral femoral cutaneous nerves was 64%, 91% and 96% in group Winnie, group PCB and group FICB, respectively, and the differences between the three groups were all statistically significant (P<0.05). The successful rate of the block of obturator nerves in group FICB (62%) was lower than that in group PCB (89%) and Winnie group (84%) (P<0.05). Conclusion Continuous fascia iliaca compartment block on perioperative analgesia in aged proximal femur surgery, with exact effect, less complications and simple operation, is better than the psoas compartment block and Winne " 3 in 1” nerve block.
