AIm: Obstruction of superior sagittal sinus (SSS) and collateral bridging veins is a well-known reason of postoperative brain edema and brain infarct, however, morphometric anatomic studies done in the light of surgical landmarks aren't sufficient in number. Object of this study is to describe venous structures related to SSS with silicon injected cadaveric models.
mATeRIAL and meTHods:This study was on 6 silicon injected cadaveric heads at Anatomy Department. Duramater was removed and veins on parasagittal area were examined. SSS morphology, veins draining into SSS, their size, number and distance were evaluated.ResuLTs: Mean vein number draining into SSS is 2.9±1.5 at anterior to coronal suture (CS), between CS and vertex is 3.2±0.8, between vertex and lambdoid suture (LS) is 2.3±0.9, between LS and confluens sinuum 0.3±0.5. There was no statically difference between right and left sides (p=0.140, p>0.05). Diameter of veins was 2.4±1.0 mm at anterior to CS, 3.0±1.2 mm at between CS and vertex, 2.4±0.7 mm at between vertex and LS, and 2.2±0.5 mm at between LS and confluens sinuum.
CoNCLusIoN:Knowing details of anatomic structures of SSS and venous structures draining into it may protect the patients from many surgical complications. SSS and related structures with surgical landmarks are valuable for neurosurgeons.
We present a case of a 47-year-old-woman with a complaint of cervical pain with paresthetic appearance on her left arm. She was treated with analgetics. Further radiological evaluation because of the persistent pain revealed an osteolytic destruction of the fourth cervical vertebra. The patient underwent anterior cervical corpectomy with total excision of the tumor. Stabilization of the cervical spine was performed. Histology confirmed the diagnosis of Langerhans cell histiocytosis (LCH) of the cervical spine. This case report presents the histopathological evaluation, diagnostic work-up and the treatment procedures, because of rarity of cervical spinal LCH cases in the literature.
INTRODUCTIONThe uncinate process (UP) has an important role because of its relationship with the vertebral artery and spinal roots. Degenerative diseases cause osteophyte formation on the UP, leading to radiculopathy, myelopathy and vertebral vascular insufficiency, which may require surgical management. This study aimed to evaluate the morphometry of this region to shed light on the anatomy of the UP.
METHODSMorphometric data was obtained from 13 male formaldehyde-fixed cadavers. Direct measurements were obtained using a metal caliper. Computed tomography (CT) morphometry was performed with the cadavers in the supine position.RESULTS Direct cadaveric measurements showed that the height of the UP increased from C3 (5.8 ± 1.0 mm) to C7 (6.6 ± 0.5 mm). On CT, the corresponding measurements were 5.9 ± 1.2 mm at C3 and 6.9 ± 0.6 mm at C7. The distance between the left and right apex of the UP from C3 to C7 also increased on both direct cadaveric and CT measurements (C3: 20.8 ± 1.0 mm and C7: 28.1 ± 2.4 mm vs. C3: 23.7 ± 3.4 mm and C7: 29.0 ± 3.0 mm, respectively). On CT, the distance between the UP and superior articular process at the C3 to C7 levels were 9.8 ± 1.7 mm, 7.9 ± 1.8 mm, 7.9 ± 1.6 mm, 7.8 ± 1.3 mm and 8.2 ± 1.7 mm, respectively.CONCLUSION Direct cadaveric and CT measurements of the UP are useful for preoperative evaluation of the cervical spine and may lead to better surgical outcomes.
Objective: To establish any changes up to the second postoperative month in pain, disability, performance, kinesiophobia, and lower extremity motor coordination of patients operated on for lumbar disc hernia. Methods: Forty-five patients with lumbar disc hernia were included in the study preoperatively, and were followed up until the second postoperative month. Pain and disability, walking and stair-climbing performances, and kinesiophobia were measured; and motor coordination tests were practiced with the Lower Extremity MOtor COordination Test (LEMOCOT). Results: The worst scores of pain, disability, performance, kinesiophobia, and LEMOCOT measurements were in the preoperative period; while the best ones were observed in the 2 months following the surgery. Conclusion: The measurements of pain, disability, performance, kinesiophobia, and lower extremity coordination usually performed in the cases operated on with a diagnosis of lumbar disc hernia are significantly affected from the initial period until the second postoperative month.
