“…Most current studies suggest that the older the operation age, the greater the risk suffering from the ASD [15,23,24], and not only was there a greater likelihood of postoperative ASD but also the risk of the ASD increased. The natural age-related degeneration has more affects than the fusion itself on the development of ASD [25].…”

BackgroundTo explore the related influencing factors of adjacent segment degeneration (ASD) after cervical discectomy and fusion (ACDF).Material/MethodsA retrospective analysis of 263 patients who underwent ACDF was carried out. Cervical x-ray and magnetic resonance imaging (MRI) were required before operation, after operation, and at the last follow-up. General information and some radiographic parameters of all patients were measured and recorded. According to the imaging data, patients were put into one of two groups: non-ASD group and ASD group. The differences between the two groups were compared by t-test and χ2-test, and the related influencing factors of ASD were analyzed by logistic regression.ResultsIn all, 138 patients had imaging ASD. Comparing the age, the postoperative cervical arc chord distance (po-CACD), and the plate to disc distance (PDD) of the two groups, differences were statistically significant (p<0.05). The gender, the fusion segment number, the pre-CACD, the pre-and-po CACD, the preoperative cervical spinal canal ratio, and the upper and lower disc height (DH) showed no statistical difference between the two groups (p>0.05). The results of logistic regression analysis showed that there were significant correlations in the following characteristics: age, postoperative po-CACD, and the PDD (p<0.05). Of all these characteristics, the correlation of age was the highest (R=1.820).ConclusionsAge, po-CACD, and PDD were risk factors for ASD after ACDF. The older the operation age, the worse the recovery was of postoperative physiological curvature of cervical spine, and a PDD < 5 mm was more likely to lead to ASD.

Background/Aim: Anterior tension band injuries are usually the result of high impact hyperextension trauma. Current surgical treatment includes anterior cervical discectomy and fusion bearing the risk of soft tissue irritation, degeneration of adjacent cervical segments, implant failure or iatrogenic spondylodesis. This study examined the biomechanical properties of tape suture constructs reenforcing ligamental stability for the treatment of Association of Osteosynthesis (AO) type B3 injuries compared to anterior fusion. Materials and Methods: After creation of an AO type B3 injury in synthetic cervical segments (C5/6, Sawbone ® ), seven segments were treated with anterior fusion and seven with a tape suture construct, similar to the SpeedBridge™ (Arthrex ® ). Biomechanical testing was performed, simulating extension, flexion, lateral bending, and rotation. Dislocation (˚) and corresponding force (N) were measured and compared. Results: Anterior fusion displayed a mean range of extension, lateral bending, and rotation of 3.60˚(SD 1.87˚), 2.28˚(SD 1.55˚), and 2.81˚(SD 0.78˚), respectively. The tape suture showed a mean range of extension, lateral bending, and rotation of 4.24˚(SD 0.81˚) (p=0.146), 5.44˚(SD 1.56˚) (p=0.013), and 5.29˚(SD 1.44˚) (p<0.01), respectively. No specimen suffered from implant failure. Conclusion: The tape suture construct provides sufficient biomechanical stability for the treatment of AO type B3 injuries compared to anterior fusion. Regarding cervical extension, whose limitation is crucial for ligamental healing, the tape suture shows no significant inferiority. Yet, the tape suture approaches physiological mobility in the planes not affected by the injury. Consequently, the tape suture is a promising alternative preventing an iatrogenic spondylodesis.

“…In the long term, degenerative disc disease frequently develops on either side of the fused segment. The potential role for interbody fusion in this outcome deserves evaluation (6) . Adjacent-segment disease is defined as radiographic deterioration of a mobile spinal segment adjacent to a fused segment.…”

Objective: To assess the clinico-radiological outcome of the fusion in anterior cervical decompression and fusion surgeries. Methods: This was a prospective cross-sectional study. Patients operated through anterior approach for cervical spine disease were included in the study. Patients were operated through anterior approach by employing Smith Robinson's technique or Cloward technique (on the basis of surgeon's preference). Inter body grafts used were iliac crest autograft, artificial G graft from Surgiwear Company. Subjective clinical evaluation was assessed by axial pain and Odom's criteria. Nurick grade was used to evaluate improvement in neurological myelopathic status. Results: A total of 62 patients were included in the study. Majority of them were males (80.6%). Majority of them were males (80.6%). Most common age group was 31-40 years. Of the three main group of disease features, degenerative was most common (64.5%). C5/6 disc space was the commonest operated level (64.5%). Iliac crest bone graft was used primarily (46/62=74%) for fusion purpose. Partial anterior graft migration (19.4%) was the most common post-op complication. The subjective assessment of improvement was excellent in 16.1% patients and good was in 45.2%. Conclusion:Best clinico-radiological improvement was found in degenerative group followed by inflammatory and traumatic.
