Abstract:
Objective To evaluate the clinical results of self-designed anterior cervical low-profile plate system (ACLPS). Methods The anterior cervical plate system, composed of one plate, two locking caps and two types of screws. The system was made of medical titanium alloy possessing the following characteristics: low profile, instant locking, versatile use and unicortical screw fixation. 37 patients with cervical disorders were fixed with ACLPS after anterior spinal decompression and interbody fusion. The diagnosis included spondylosis in 8 cases, cervical intervertebral disk protrusion in 12, fracture and /or dislocation with paralysis in 14 and metastatic tumor in 3. The fusion were performed with autologous iliac crest bone graft for 29 patients while the others with cages. The fixed levels ranged from C3 to T1. Results 37 cases were followed-up for an average of 9.6 months, ranging from 6 to 12 months. Postoperatively all patients felt comfortable in neck without any foreign body sensation. No obvious complications such as wound infection, hematoma, asphyxia, nerve injury, laceration of spinal cord dura, leakage of cerebrospinal fluid, bleeding and nonhealing of the wound were observed. Solid interbody fusion were achieved in all cases. According to JOA scores, the total effective rate was 94.6% while the good rate was 83.8%. The radiograph confirmed that there was no dislocation or subsidence of graft, no obvious loss of intervertebral height, no loosening or failure of implant. Conclusion In regard to the high rigidity, good bony purchasing and easy handling, ACLPS is able to provide sufficient biomechanical stability and is an optional choice for clinical use.
