Surgical Treatment of the Patients with Cervical Disc Herniation at Clinical Center of University of Sarajevo, Bosnia and Herzegovina

Backgroud: Intervertebral disc herniations are caused by rupture of the fibrous ring and migration of one part of the nucleus pulposus towards the spinal canal. The most commonly affected levels are C5-C6 and C6-C7. Surgical treatment of cervicobrachialgia is indicated in the presence of long-term intense pain syndrome with or without radicular sensory-motor deficit and magnetic resonance (MRI) verified disc herniation with a compressive effect. Objective: The most common surgical treatment is anterior lateral microdiscectomy with or without the use of implants. In addition to this method, dorsolateral microsurgical treatment can be used for foraminal hernias. Methods: This retrospective study included 110 (58 / 52.7% male and 52 / 47.3% female) patients with cervical disc herniations who were surgically treated at the Neurosurgery clinic of Clinical Center of Sarajevo University (CCUS) in a five-year period. Stability, postoperative curvature, arthrodesis, implants, and changes in adjacent segments were radiographically analyzed. In the outcome assessment, functional outcome and patient satisfaction were analyzed using the Pain Self-Evaluation Scale (VAS), Prolo functional and economic score, and White’s classification of treatment outcomes. Results: The dominant prevalence of changes was recorded at the levels of C5-C6 (58%) and C4-C5 (28%) with a ventrolateral approach performed in 90% of patients. The largest representation is hard dorsolateral discs (n = 77). In the group of patients with placed implant, hard discs were present in 96 (90%) cases (p <0.001), while soft discs were dominant in patients without implant placement (p <0.001). In the group of subjects with implant, the most common are hard dorsolateral discs and those of mixed localization in 41 of 55 patients (65.5%; p = 0.001). The most common implant is PEEK cage (74.5%). From complications, we had partial vertebral body fractures in 4.5% of patients. Furtehr, the most common are sensory disturbances in 2.73% of respondents. Reduction of symptoms and improvement of preoperative neurological status were observed in over 95% of patients. Conclusion: Surgical treatment of cervical disc herniation is a safe method with a minimal percentage of complications. Microsurgical discectomy significantly contributes to the improvement of the functional status of patients, the reduction of pain, and the improvement of neurological deficit and overall mobility.
