“…[27][28][29][30][31] Many of the recently introduced technologies for distal interlocking aim to reduce radiation exposure by decreasing the number of radiographic images required to perform the procedure. 7,[32][33][34][35] In the current study, we found that both the mean and the variance of the number of fluoroscopic images acquired were lower when using VAF for distal interlocking. This may be a sign of increased reproducibility for the surgeons when using the technique.…”

Background We aimed to assess the feasibility of a video‐augmented fluoroscopy (VAF) technique using a camera‐augmented mobile C‐arm (CamC) for distal interlocking of intramedullary nails. Methods Three surgeons performed distal interlocking on seven pairs of cadaveric bovine carpal bones using the VAF system and conventional fluoroscopy. We compared radiation exposure, procedure time, and drilling quality between the VAF system and conventional fluoroscopic guidance. Results Distal interlocking using VAF significantly reduced the number of fluoroscopic images compared with conventional fluoroscopy (P < 0.05). No significant difference in overall procedure time (P = 0.96) or drilling quality (P = 0.12) was detected. VAF demonstrated improvement in radiation exposure when used by a less experienced surgeon (P < 0.05). Conclusion VAF is a feasible technique for distal interlocking. Overlaid visualization of the osseous anatomy in relation to the surgical field of view appears to improve surgeons' perception of relevant structures and their spatial orientation for the use of surgical instruments.

“…Rotational deformities can be reduced by rotating the traction bow inward or outward. Ciftdemir et al applied the electromagnetic-manual guided distal locking technique to prevent malrotation in femoral shaft fractures treated using IM nails [13]. Using the rapid reductor, all 22 displaced femoral shaft fractures exhibited anatomical or nearly anatomical reduction.…”

“…3 The rapid reductor is connected to the ASIS via its proximal end and to the proximal tibia via its traction bow at the distal end, and a mechanical closed-loop traction system is formed clinical evaluation was performed at each follow up. The alignment of the lower extremity was assessed using a cord which was stretched straight from the ASIS to second metatarsal to observe whether the cord passed through the midpoint of the patella [13].…”

Background:Although the method has been used widely, one of the greatest challenges for intramedullary nailing is to position the distal locking screw. A new technology, the electromagnetic navigation system, is a radiation-free way to locate the position of the drill bit and provide 3-dimensional real-time feedback of location and orientation of the drill bit relative to the locking holes. The purpose of our study was to evaluate the reliability and efficiency of the free-hand technique compared to the new electromagnetic navigation system.Methods:Fifty-four patients with femoral fracture who needed treatment with intramedullary nails were divided into 2 groups. One group including 26 patients underwent distal locking using the standard free-hand method, whereas the electromagnetic navigation system was used with the other 29 patients. Intraoperative fluoroscopy exposure times, screw insertion times, and healing times were recorded; these parameters were used for comparison between the 2 groups.Results:There were 17 males and 9 females who had femoral intramedullary nails using the free-hand technique, whereas 21 males and 8 females received intramedullary nails using the electromagnetic navigation system. The mean time of distal locking was 19.5 ± 6.0 minutes in the free-hand (FH) group, whereas the time was 6.1 ± 1.4 minutes in the electromagnetic (ET) group. The exposure time for the FH group was 26.8 ± 13.3 seconds and 2.2 ± 1.1 seconds for the ET group. Healing time proved to be comparable in the FH and ET groups (16.4 ± 3.7 weeks vs 15.1 ± 2.8 weeks).Conclusion:Under the premise of achieving the same effect, the electromagnetic navigation system has the advantage of less distal locking time and less radiation dose.

Does electromagnetic-manual guided distal locking influence rotational alignment in antegrade femoral nailing?

Abstract: Although there is no significant effect on malrotation, previously known advantages lead us to state that electromagnetic-manual guided distal interlocking is an advantageous treatment option in femoral shaft fractures.
