SURGICAL TREATMENT OF DEGENERATIVE DISEASES OF THE LUMBAR SPINE IN PATIENTS WITH OVERWEIGHT AND OBESITY

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.

Background: The provision of surgical care in the treatment of degenerative diseases of the lumbar spine in patients with obesity and obesity is associated with significant risks of anesthesia and the development of perioperative complications. Aims: to analyze the results of the introduction of a combination of surgical procedures and anesthesia in the treatment of multilevel degenerative diseases of the lumbar spine in patients with excessive body weight and obesity.Materials and methods: The results of surgical treatment of 86 patients were studied, 2 groups were identified. In the study group (SG, n=37), minimally invasive surgical techniques and original surgical approach, paravertebral musculature infiltration with bupivacaine with epinephrine, and multimodal anesthesia with dexmedetomidine were used. The comparison group (CG, n=49) consisted of patients who used the technique of traditional open transpedicular fixation in combination with the posterior interbody fusion without the above combination of surgical procedures and anesthesia. Observation and clinical evaluation was performed in the early (during hospitalization) and in the distant (on average 36 months) postoperative periods.Results: In SG there were no changes in hemodynamics and better results were obtained on the speed of recovery of psychomotor functions. The use of local anesthetics significantly reduced the local pain syndrome (p0.05) and the need for analgesics (p=0.002). Comparative analysis in the main group revealed significantly better results in indices of the duration of the operation [SG 145 (105; 155) min, CG 185 (100; 205) min; p=0.02], the volume of blood loss [SG 110 (90; 140) ml, CG 510 (390; 640) ml; p0.001], the activation time [SG 1 (1; 2) days, CG 3 (3; 4) days; p=0.01], the length of hospitalization [SG 10 (9; 11) days, CG 13 (12; 15) days; p=0,03], remote clinical parameters of the pain syndrome level from the visual analogue scale in the lower extremities [SG 3 (1; 4) mm, CG 9 (6; 14) mm; p=0.006] and the lumbar spine [SG 6 (4; 9) mm, CG 16 (11; 21) mm; p=0.001], functional state according to ODI [SG 8 (6; 10) points, CG 16 (12; 24) points; p=0.008], subjective satisfaction with the operation performed on the Macnab scale (p=0.01). The number of postoperative complications in SG was 8%, in CG ― 18% (p=0.006).Conclusions: Analysis of the results of the introduction of a combination of surgical and anesthetic support methods in the treatment of multilevel degenerative diseases of the lumbar spine in patients with overweight and obesity, including minimally invasive surgical techniques, infiltration of paravertebral muscles with bupivacaine and epinephrine, multimodal anesthesia with dexmedetomidine showed its high perioperative safety, low number of complications, as well as better and clinical outcomes in the early and late postoperative periods.
