ABSTRACT
Objective: To observe value of 3D navigation assisted percutaneous vertebroplasty (PVP) combined with postoperative lower-back muscles training in treatment of osteoporotic vertebral compression fracture (OVCF). Methods: Twenty-five consecutive patients with OVCF were enrolled in observation group and treated with 3D navigation assisted PVP using O-arm scanner and postoperatively systematic back muscle exercise, while other 25 OVCF patients in control group were treated with traditional C-arm assisted PVP and postoperatively regular back muscle exercise. Intraoperative fluoroscopy time, mean dose of radiation, mean procedure time, visual analogue score (VAS) before and 2 h, 1 month, 3 months, 6 months after operation were compared between the two groups. Technical success rate was calculated, and vertebral leakages and complications were observed. Results: Technical success rate of the two groups were both 100% (25/25). The duration of fluoroscopy and operation were shorter, the radiation dose was lower in observation group (all P0.05). Conclusion: PVP guided with 3D navigation combined with postoperative lumbar and dorsal muscle training can safely and effectively treat OVCF, shorten the operation time, reduce radiation exposure and improve the medium and long-term pain symptoms after PVP.
ABSTRACT
BACKGROUND:Navigation assisted minimal y invasive posterior lumbar interbody fusion and pedicle screw fixation can precisely real-time guide a variety of operation under minimal y invasive sleeve, and implant the pedicle screws and interbody fusion cage and other implants safely and accurately, thus can determine the decompression parts. Minimal y invasive transforaminal lumbar interbody fusion is the typical approach in recent years for the successful application of minimal y invasive spine surgery techniques with the advantages of smal incision, less bleeding, slight tissue damage and faster recovery. OBJECTIVE:To evaluate the short-term effect of minimal y invasive transforaminal lumbar interbody fusion with real-time three-dimensional navigation system and open posterior transforaminal lumbar interbody fusion. METHODS:Forty cases with single-level lumbar disc herniation were retrospectively analyzed. The patients were treated with minimal y invasive transforaminal lumbar interbody fusion with real-time three-dimensional navigation system (20 cases) and open posterior transforaminal lumbar interbody fusion (20 cases) respectively for the comparative analysis. The fusion duration, intraoperative blood loss, postoperative drainage volume, the length of postoperative hospital stay and the length of hospital stay were compared between two groups. The wound pain and function were evaluated after treatment with visual analogue scale score and Japanese Orthopaedic Association score. RESULTS AND CONCLUSION:Al patients were fol owed-up for 7.7 months. The operative duration in the minimal y invasive transforaminal lumbar interbody fusion group was longer than that in the open posterior transforaminal lumbar interbody fusion group, and the difference was significant (P0.05).The results indicate that minimal y invasive transforaminal lumbar interbody fusion with real-time three-dimensional navigation system is an effective method for lumbar disc herniation with the advantages of less intraoperative blood loss, less postoperative drainage volume, smal trauma, short hospital stay and short-term efficacy.
ABSTRACT
Objective To study the work principle and key technologies of digital surgery navigation system of Stryker NavSuiteTM.Methods Applying principles which contained intelligence tracing,virtual reality,image processing,system registration and so on,surgery navigation system constructed three-dimensional virtual anatomy of the patient to realize the precise navigation in surgery.Results The navigation system could provide real-time and three-dimensional navigation safely,precisely and reliably.This system assisted doctor to complete the extremely difficult minimal invasive surgery.Conclusion The digital surgery navigation system is the most advanced and innovative technique.This system is one of the important parts of digital operating room.It is also significant for promoting the hospital to obtain the maximum economic benefit and social benefit.
