Analysis of lumbosacral sagittal balance parameter variation in minimally invasive transforaminal lumbar interbody fusion with real-time 3D navigation techniques / 中国骨伤

OBJECTIVE@#To explore the dynamic changes of lumbosacral sagittal parameters after real-time three-dimensional navigation assisted minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and traditional open TLIF for treatment of lumbar degenerative disease.@*METHODS@#The clinical data of 61 patients with lumbar degenerative disease underwent single-segment surgery from September 2017 to September 2019 were retrospectively analyzed. Among them, 31 cases underwent MIS-TLIF with 3D navigation techniques (MIS-TLIF group) and another 30 cases underwent conventional open TLIF (traditional open TLIF group). The basic information, operative time and intraoperative blood loss were collected. The sagittal radiologic parameters were measured before surgery and 3 months after surgery, including lumbar lordosis (LL), segmental lordosis (SL), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), anterior disc height (ADH), posterior disc height(PDH).And the average disc height(DH) and pelvic incidence to lumbar lordosis mismatch (PI-LL) were calculated.@*RESULTS@#Operative time and intraoperative blood loss in MIS-TLIF group were significantly less than in traditional open TLIF group(@*CONCLUSION@#Real-time navigation-assisted MIS-TLIF and traditional open TLIF can recover DH in a short term for lumbar degenerative diseases, improve LL and PI-LL, and make the arrangement of the sagittal plane of the lumbosacral region more coordinated after surgery. But only the navigation assisted MIS -TLIF can significantly improve SL. Compared with traditional open TLIF, real-time navigation assisted MIS-TLIF in the treatment of degenerative lumbar diseases has the advantages of short operation time and less intraoperative bleeding.

Supraorbital keyhole approach for microsurgical treatment of aneurysms in the anterior circulation / 中华外科杂志

<p><b>OBJECTIVE</b>To study the method with endoscope-assisted microsurgical technique through the supraorbital keyhole approach to treat aneurysms in the anterior circulation.</p><p><b>METHODS</b>According to preoperative diagnostic imagings, to work out of the individual operation planning. Skin incision was made in the eyebrow, and the diameter of supraorbital craniotomy was about 2 cm, endoscope-assisted microsurgical technique was used to clip aneurysm. The technique was used in the most recent 12 consecutive patients.</p><p><b>RESULTS</b>Five different kinds of aneurysms in the anterior circulation were clipped through this method and 12 patients were cured. One patient, intraoperative accidental aneurysm rupture occurred. There were no approach-related complications.</p><p><b>CONCLUSIONS</b>This endoscope-assisted microsurgical technique via supraorbital keyhole approach is a safe, minimal invasive and effective way for the treatment of aneurysms in the anterior circulation, and there is more sufficient operating space.</p>

Endoscope-assisted supraorbital keyhole approach for excision of suprasellar region tumor / 中华外科杂志

<p><b>OBJECTIVE</b>To study endoscope-assisted microsurgical technique with supraorbital keyhole approach for the treatment of suprasellar region tumor so as to maximize tumor removal and minimize operative-trauma.</p><p><b>METHODS</b>According to high resolution CT and MR images before operation, individual operation schemes were worked out. Skin incision was made in the eyebrow, and the diameter of supraorbital craniotomy was approximately 2 cm. Endoscope-assisted microsurgical technique was used to resect lesions in 16 consecutive patients.</p><p><b>RESULTS</b>Total Tumors were removed in all of the 16 patients via the supraorbital keyhole approach. No postoperative complications occurred.</p><p><b>CONCLUSIONS</b>Supraorbital keyhole approach may diminish tissue injury considerably and has proven to provide sufficient operating space in the suprasellar region for tumor removal.</p>
