Abstract Background: To analyze risk factors of titanium mesh cage (TMC) subsidence in single-level anterior cervical corpectomy and fusion (ACCF) for cervical ossification of the posterior longitudinal ligament (OPLL). Methods: Patients with cervical OPLL who were treated with single-level ACCF between January 2019 to December 2019 were retrospectively analyzed in two groups: patients with TMC subsidence as Group S, and patients with no TMC subsidence as Group N during the one-year follow-up period. The degree of distraction between decompression of the vertebral bodies and correction of the cervical curvature was measured to analyze their relationship with TMC subsidence. Results: There was no significant difference in patient demographics and complications between the two groups. The degree of distraction in Group S was significantly higher than that in Group N. The change of C2 to C7 Cobb angle (α) in Group S was significantly greater than that in Group N, and the interspinous process distance (SPD) in Group S was also significantly greater than that in Group N. The JOA score and JOA recovery rate were not statistically different between the two groups.Conclusions: Intraoperative selection of overlength TMC in single-level ACCF for OPLL, over-distraction, and excessive correction of the cervical curvature may cause TMC subsidence after surgery. No significant impact of TMC subsidence on the surgical outcome was observed during the 1-year follow-up period.

Anterior Cervical Corpectomy

AbstractFusion with a titanium mesh cage (TMC) has become popular as a conventional method after cervical anterior corpectomy, but postoperative TMC subsidence has often been reported in the literature. We designed a novel anatomic cervical TMC to reduce the postoperative subsidence rate. According to the test process specified in the American Society of Testing Materials (ASTM) F2267 standard, three-dimensional finite element analysis was used to compare the anti-subsidence characteristics of a traditional TMC (TTMC) and novel TMC (NTMC). Through analysis, the relative propensity values of a device to subside (Kp) of the TTMC and NTMC were 665.5 N/mm and 1007.2 N/mm, respectively. A higher Kp measurement is generally expected to indicate that the device is more resistant to subsidence into a vertebral body. The results showed that the novel anatomic titanium mesh cage (NTMC) significantly improved the anti-subsidence performance after anterior cervical corpectomy and fusion (ACCF), which was approximately 51.3% higher than that of the traditional titanium mesh cage.

Comminuted Fractures

SummaryIn this case report, we describe the use of a cylindrical titanium mesh cage combined with cancellous bone graft to surgically manage large segmental bone defects in a dog. A seven-year-old, neutered male cross-breed dog, with highly comminuted fractures of the right femur and the left radius and ulna, was referred for treatment. Previous open reduction and internal fixation of these fractures had failed. Following implant removal and debridement of each bone, a 71 mm segmental femoral defect and a 27 mm segmental radial defect were present. A commercially available cylindrical titanium mesh cage was filled with ß-tricalcium phosphate crystals mixed with an equal volume of autogenous cancellous bone graft. The mesh cage was aligned with the proximal and distal parts of each bone using an intramedullary pin passing through the cage, and a locking plate was applied to the proximal and distal fracture fragments to produce compression against the titanium cage. The dog had a successful long-term clinical outcome, and radiographic examination at 22 and 63 weeks after surgery showed the formation of remodelling bridging callus that was continuous across the titanium cage in each of the fractures. Due to the relative simplicity of the technique and the favourable outcome in this case, it should be considered an option when managing comminuted fractures with large bone defects.
