Transpedicular Stabilization

Objective. To clarify indications for dynamic and rigid stabilization based on the analysis of correlation between neuroimaging parameters of facet joints (FJ) and clinical outcomes of surgical treatment of patients with degenerative diseases of the lumbar spine. Material and Methods. A total of 141 patients with degenerative diseases of the lumbar spine were surgically treated. Patients were divided into three groups: patients of Group I (n = 48) underwent surgical intervention with artificial intervertebral disc prosthesis; those of Group II (n = 42) – with interbody fusion and combined transpedicular and transfacetal stabilization; and those of Group III (n = 51) – with interbody fusion and bilateral transpedicular stabilization. The correlation between long-term clinical outcomes (pain syndrome according to VAS, functional state according to ODI, and satisfaction with surgical result according to MacNab scale) and preoperative neuroimaging parameters of FJ (degenerative changes according to Fujiwara, facet angle magnitudes, and the presence of tropism) was analyzed. Results. A direct significant nonparametric correlation of neuroimaging parameters of facet angles and FJ tropism with long-term clinical outcomes of surgical treatment according to VAS and ODI was revealed. It was established that good clinical outcomes were achieved with the following preoperative parameters: in Group I, the facet angle was less than 60°, while the presence of tropism had no correlation dependence; in Group II, the facet angle – more than 60°, in the absence of FJ tropism; and in Group III, the facet angle – more than 60°, in the presence of FJ tropism. Conclusion. Objective neuroimaging parameters of the facet angle magnitude of less than 60°, regardless of the presence of tropism, allow performing total arthroplasty. If the facet angle is more than 60°, the rigid stabilization of the operated segment is indicated; in the absence of tropism, a contralateral transfacetal fixation is possible, and in its presence – a bilateral transpedicular stabilization is reasonable.

ABSTRACT Objective: To analyze the impact of the relationship between tropism and angulation of the lower lumbar facet joints on a remote clinical outcome after dynamic and rigid surgical interventions. Methods: Patients with degenerative diseases of the lower lumbar spine were subdivided into three groups, according to the method of surgical treatment: 1) (n=48) the use of an artificial prosthesis intervertebral disc (IVD); 2) (n=42) the use of interbody fusion combined with transpedicular and transfacet stabilization; 3) (n=51) the use of interbody fusion and bilateral transpedicular stabilization. Analysis was performed of the remote clinical parameters and neuroimaging characteristics before the operation was performed. Results: When analyzing clinical and instrumental parameters, a significant correlation was found between the long-term outcomes of surgical treatment on the VAS and Oswestry scales and the neuroimaging data on angulation and tropism of the facet joints (FJ). Conclusions: The data obtained testify to the importance of preoperative diagnosis of tropism and angulation of the lower lumbar facet joint, which enables differentiated surgical tactics to be selected, and remote clinical outcomes to be optimized. In the presence of neuroimaging parameters of Facet Joint angulation of less than 600, regardless of the presence of tropism, it is possible to perform total arthroplasty of IVD. When neuroimaging parameters of Facet Joint angulation of more than 600 are detected, rigid stabilization of the operated segment is recommended, while in the absence of tropism of Facet Joints, a contralateral transfacetal fixation is possible; in the presence of tropism, it is expedient to perform bilateral transpedicular stabilization.

Background: The technique of lateral lumbar interbody fusion for the surgical treatment of patients with degenerative diseases of the lumbar spine was developed in the early 2000s. But at the same time in modern literature there is no uniform approach to the use this technique, clinical outcomes and radiological findings are contradictory. Aims: to conduct a multicenter analysis of clinical outcomes and instrumental data of direct lateral interbody fusion (DLIF) approach combined with transcutaneous pedicle fixation in patients with single-level degenerative disc diseases of the lumbar spine. Materials and methods: The study included 103 patients (63 men and 40 women, mean age 45.8±9.7 years) who underwent surgery followed by DLIF transcutaneous pedicle fixation. The surgery was performed at neurosurgical and vertebrological departments in Irkutsk (Russia), Omsk (Russia), and Astana (Kazakhstan). Dynamic observation and comprehensive clinical and instrumental evaluation of the treatment results were carried out for an 18-month period after surgery. Results: After the simultaneous decompressive-stabilizing intervention, in all patients we detected a decrease in the severity of pain syndrome on VAS — from 6.9±1.6 to 1.7±1.2 cm (p0.001), and improved quality of life index (Oswestry) — from 21.3±6.8 to 12.3±4.4% (p0.001). The instrumental methods of examination determined the effective indirect decompression: an increase in the size of interbody gap in the middle of its department compared with the preoperative value from 8.6±3.1 to 15.7±4.2 mm (p0.001) and an increase in the area of the intervertebral foramen (on the left with an average of 98.7±32.3 and 156.8±45.1 mm2, p0.001; on the right —99.7±37.3 to 153.4±38.7 mm2, p0.001). We also registered the restoration of both the segmental (from 10.2±3.8 to 13.6±6.7°, p0.001) and regional (from 32.8±5.9 to 48.2±7.3°, р0.001) lumbar lordosis. Complete interbody fusion was diagnosed in 87 (86.4%) patients. Complications were observed in 8.7% of cases. Conclusions: DLIF technique combined with transcutaneous transpedicular stabilization has high clinical efficacy confirmed by significant reduction in the severity of pain according to VAS. The studied approach improves the quality of life of patients by Oswestry index and reveals a low number of postoperative complications. The described simultaneous minimally invasive method of surgical treatment in patients with degenerative disc diseases allows to restore the sagittal profile of the lumbar spine and implement an effective stabilization of the operated vertebral-motor segments with a high degree of formation of interbody bone block.

Objective. To evaluate the relationship between the radiological and neuroimaging parameters of the spinal motion segment and the clinical outcome of surgical treatment of patients with degenerative diseases of the lumbosacral junction to clarify the indications for dynamic and rigid stabilization.Material and Methods. The study included 267 patients with degenerative diseases of the lumbosacral spine. Depending on the stabilization method, patients were divided into two groups: Group I (n = 83) with dynamic intervertebral disc (IVD) prosthesis; and Group II (n = 184) with interbody fusion and transpedicular fixation. Long-term clinical parameters and biomechanical characteristics before and after surgery were analyzed.Results. A significant nonparametric correlation of the long-term result of surgical treatment assessed by VAS and Oswestry Disability Index with radiological parameters and results of neuroimaging was revealed. It was determined that the use of artificial IVD allows achieving a minimum level of pain syndrome and good functional recovery with effective preservation of the volume of physiological movements in the operated segment and restoration of the total angle of lumbar lordosis.Conclusion. Objective neuroimaging data (grade II-IV of degeneration according to the measured diffusion coefficient) and radiological parameters (linear displacement of vertebrae not more than 4 mm, sagittal volume of movements in the spinal motion segment less than 6°, decrease in the height of intervertebral disc space no more than 2/3 of the superjacent one) make possible using total arthroplasty. It is advisable to perform interbody fusion and rigid stabilization in grade IV-V of degeneration, linear displacement of vertebrae more than 4 mm, sagittal volume of movements of at least 6°, and decrease in the interbody space height over 2/3 of the superjacent one.

Study Objective

Background. Minimally invasive technology of fusion broadly introduced in clinical practice represent one of modern trends in spinal surgery on the other hand those technical solutions lack to provide posterior fusion. As a consequence, patients treated with minimally invasive techniques are vulnerable in terms of pseudarthrosis and implant instability therefore measures focused on those complications’ prevention are still actual.The study objective is to evaluate efficacy and safety of suggested percutaneous facet joints arthrodesis technique as an auxiliary option to interbody fusion.Materials and methods. This is a prospective non-randomized study of 80 patients with degenerative diseases of the lumbar spine who were treated applying minimally invasive transforaminal lumbar interbody fusion, lateral lumbar interbody fusion and anterior lumbar interbody fusion. In 20 cases out of those enrolled interbody fusion was supplemented with percutaneous posterior facet joints arthrodesis. Computed tomography was administered at the period of 6 and 12 months after surgery to assess anterior and posterior fusion. The minimal follow-up period accounted for 12 months.Results. The suggested percutaneous facet joints arthrodesis fifty-fold increased the probability of posterior fusion formation compared to the rate of spontaneous spinal fusion (p <0.0001, logistic regression was applied). In three cases posterior fusion formed prior to interbody fusion providing stability of segment operated on. No adverse events and no complications associated with percutaneous arthrodesis were detected.Conclusion. The suggested percutaneous facet joints arthrodesis is safe and effective minimally invasive technique that facilitates additional posterior spinal fusion formation in a short-term period herewith decreasing symptomatic pseudarthrosis development in patients operated on using minimally invasive spinal fixation and fusion.

Objective To study the radiologic characteristics of facet joints at different stages of the degenerative process in the lumbar spine to determine the indications for various methods of fixing the affected segment and to evaluate the results of treatment.Material and Methods To determine the radiologic aspects of facet joints in the affected area and in  adjacent segments of the lumbar spine, two groups were formed, including 136 patients who underwent multispiral computed tomography in two-energy mode before surgery and 12 months after surgery. Group I included patients who underwent rigid fixation of the spine (360°), and group II included patients who underwent dynamic fixation using nitinol rods (180°).Results Based on a comprehensive instrumental study, it was found that the degeneration of the intervertebral disc according to Pfirrmann II and III revealed an increase in the density of the cartilaginous plate in facet joints (HU). These digital indicators confirm the preservation of joint functionality, both in the affected area and in adjacent segments. With severe degrees of disk degeneration in Pfirrmann IV and V and facet joints, deep pathological changes occurred, directed towards the loss of facet joints functionality.Conclusion The obtained digital indicators of dual-energy computed tomography for the state of facet joints  in combination with the results of magnetic resonance imaging can be used as criteria in a complex of patient studies to assess the degree of degeneration of the vertebral motion segment in the affected area and adjacent segments. We recommend using these criteria as a diagnostic component for finding optimal methods of surgical treatment.

Background: For the treatment of patients with degenerative diseases of the lumbar spine the technique of pedicle fixation is widespread, when after open decompression channel structure locking screws are introduced into the vertebral body through the back vertebra legs. We first used a fundamentally new way of fixing the rear using the facet-boards Cage «Facet Wedge», when posterior fixation is done by closing the facet joints with minimally invasive, percutaneous method. We have not found data on the clinical efficacy of facet fixation in scientific literature.Aims: To compare the clinical efficacy of facet fixation combined with interbody fusion in the treatment of patients with degenerative lumbar spine disease.Materials and methods: The study included 145 patients who were divided into 2 groups. The study group with long-term observation included patients (n=100) who underwent a new method for lumbar fixation; the method comprises unilateral or bilateral implantation of titanium Cage «facet Wedge» in the joint space facet joint in combination with the anterior, lateral, and transforaminal interbody fusion. Clinical comparison group (n=45) included retrospectively recruited patients who were performed titanium pedicle screw installation after open decompression and interbody fusion posterior lumbar fixation. Dynamic observation and comprehensive evaluation of the treatment clinical results was carried out for 18 months after surgery.Results: Cage facet installation technology is quite simple, universal for the stabilization of the rear of the complex after interbody fusion from the front, side, and rear access; and does not require the intraoperative application of expensive high-tech equipment. Comparative analysis of the main group showed significantly better results in terms of the duration of the operation [CG 125 (90; 140) min, the CCG 205 (160; 220) min; p=0.01], the volume of blood loss [CG 80 (70; 120) ml, CCG 350 (300; 550) ml; p=0.008], activation time [CG 2 (1; 2) days, 4 CCG (3; 5) days; p=0.02], length of hospitalization [CG 9 (10; 11) days, the CCG 13 (12; 15) days; p=0.03], the level of pain on a visual analog scale [CG 3 (2; 4) mm, CCG 15 (12; 18) mm; p=0.001], quality of life (by index Oswestry) [CG 8 (6; 8) points, the CCG 23 (20; 28) points, p=0.003], and labor rehabilitation [CG 3 (2; 6) months, CCG 9 (6; 12) months; p=0.0001]. The number of postoperative complications in group 1 was 13%, in the 2nd ― 31,1% (p=0,0012). The new method involves fixing the back with considerably less surgical trauma of paravertebral soft tissue that results in early activation of patients, reduction of stay in hospital period, and better functional recovery of patients.Conclusions: The application of facet fixation combined with interbody fusion in the treatment of patients with degenerative diseases of the lumbar spine allows achieving the best clinical outcomes and fewer postoperative complications during the short and long-term follow-up if compared with the traditional method of transpedicular stabilization. The combination of low-impact and reliability facet fixation techniques for posterior stabilization of the operated segment creates favorable conditions for the restoration of a functional condition of patients, full social and physical rehabilitation.
