Anterior Cruciate Ligament Femoral Socket Preparation Using a Cannulated, Calibrated Drill With Adjustable Stop and Slotted Cannula.

ABSTRACT: Anteromedial portal-guided femoral tunnel preparation during anterior cruciate ligament reconstruction can be difficult owing to poor visualization. This may cause iatrogenic damage to the medial femoral condyle cartilage and the posterior cruciate ligament fibers or overdrilling through the lateral femoral cortex, creating difficulties in the use of femoral suspensory devices during anterior cruciate ligament reconstruction. We describe an accurate and safe technique for femoral graft socket preparation using a cannulated, calibrated drill with an adjustable stop and slotted cannula. This easy and reproducible technique uses simple additional instruments and effectively addresses concerns related to femoral graft socket preparation, without requiring additional surgical time.

Project description:ObjectiveTo compare the effects between computer-assisted and traditional cannulated screw internal fixation on treating femoral neck fracture.MethodsThe search was conducted in Embase, Pubmed, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI) and Wanfang Database from the beginning to August 2020. RevMan5.4 software, which was provided by the International Cochrane Group, was used for the meta-analysis comparing the differences in operation time, intraoperative bleeding volume, fluoroscopy frequency, fracture healing time, total drilling times, Harris score, fracture healing rate, and femoral head necrosis rate between computer-assisted and traditional methods groups.ResultsA total of 1028 patients were included in 16 studies. Primary outcome indicators: Compared with the traditional method group, the computer-assisted group had less operative time (2RCTs, P < 0.00001; 8 non-RCTs, P = 0.009; Overall, P < 0.00001), intraoperative bleeding (1 RCTs, P < 0.00001; 9non-RCTs, P < 0.00001; Overall, P < 0.00001), femoral head necrosis rate (1 RCT, P = 0.11;7 non-RCTs, P = 0.09; Overall, P = 0.02) and higher Harris scores (1 RCT, P < 0.0001; 9 non-RCTs, P = 0.0002; Overall, P < 0.0001), and there were no significant differences in fracture healing rate between the two groups (5 non-RCTs, P = 0.17). Secondary outcomes indicators: The computer-assisted group had a lower frequency of intraoperative fluoroscopy and total number of drills compared with the traditional method group, while there was no significant difference in fracture healing time.ConclusionCompared with the traditional hollow screw internal fixation on the treatment of femoral neck fracture, computer-assisted percutaneous cannulated screw fixation can shorten the operation time and improve the operation efficiency and reduce the X-ray injury of medical staff and help patients obtain a better prognosis. Therefore, computer-assisted percutaneous cannulated screw fixation is a better choice for the treatment of femoral neck fracture. Study registration PROSPERO registration number CRD42020214493.
