Pedicle screw surface coatings improve fixation in nonfusion spinal constructs.
STUDY DESIGN Biomechanical and histologic analysis. OBJECTIVE To compare the strength of the bone-screw interface of standard uncoated pedicle screws with screws treated with hydroxyapatite (HA), titanium plasma spray (TPS), and a composite HA-TPS coating. SUMMARY OF BACKGROUND DATA Transpedicular screw fixation has become the gold standard in the treatment of various thoracolumbar spinal c...
متن کاملDecompressive cervical laminectomy and lateral mass screw-rod arthrodesis. Surgical analysis and outcome
BACKGROUND This study evaluates the outcome and complications of decompressive cervical Laminectomy and lateral mass screw fixation in 110 cases treated for variable cervical spine pathologies that included; degenerative disease, trauma, neoplasms, metabolic-inflammatory disorders and congenital anomalies. METHODS A retrospective review of total 785 lateral mass screws were placed in patients...
متن کاملComparison of Outcomes after Atlantoaxial Fusion with Transarticular Screws and Screw-Rod Constructs
OBJECTIVE The purpose of this study was to compare the radiological and neurological outcomes between two atlantoaxial fusion method for atlantoaxial stabilization; C1 lateral mass-C2 pedicle screws (screw-rod constructs, SRC) versus C1-2 transarticular screws (TAS). METHODS Forty-one patients in whom atlantoaxial instability was treated with atlantoaxial fixation by SRC group (27 patients, f...
متن کاملThe effect of different screw-rod design on the anti-rotational torque: a biomechanical comparison of three conventional screw-rod constructs
BACKGROUND Screw-rod constructs have been widely used to correct spinal deformities, but the effects of different screw-rod systems on anti-rotational torque have not been determined. This study aimed to analyze the biomechanical effect of different rod-screw constructs on anti-rotational torque. METHODS Three conventional spinal screw-rod systems (Legacy, RF-F-10 and USSII) were used to test...
متن کاملGallie technique versus atlantoaxial screw-rod constructs in the treatment of atlantoaxial sagittal instability: a retrospective study of 49 patients
BACKGROUND The objectives of this study are to investigate the clinical curative effect of Gallie technique and atlantoaxial screw-rod constructs (SRC) on atlantoaxial sagittal instability and determine the indication of Gallie technique. METHODS Data of 49 patients with atlantoaxial sagittal instability from February 2008 to May 2015 were analyzed retrospectively. The visual analog scale (VA...
