寰枢椎椎弓根钉固定治疗伸直型齿状突骨折合并寰枢关节半脱位

Objective To explore the clinical outcome of atlantoaxial pedicle screw instrument in treatment of extension-type odontoid fracture combined with aflantoaxial subluxation. Methods From December 2002 to December 2006, seven patients with extension-type odontoid fracture combined with at-lantoaxial subluxation were reduced and fixed with atlantoaxial pedicle screw instrument of Vertex system under general anesthesia. There were five males and two females, at mean age of 39.2 years (range 21-59 years). All odontoid fractures were fresh type Aderson Ⅱ. JOA scores of spinal core function was 8.6-14.9 (average 10.7) preoperatively. The X-ray examination, CT scanning and skull traction were performed in all patients preoperatively. Results There found no severe complications such as injuries of vertebral artery, nerve root and spinal cord postoperatively. All patients obtained complete reduction and healing of the fracture and dislocation. The mean off-bed time was four days (3-6 days) after opera-tion. A follow-up for 12-36 months (average 22 months) in all patients showed that the clinical symptom was improved significantly six months postoperatively and that all screws were in proper position verified by X-ray and CT scanning. All patients obtained solid bony union on radiographs, with no loosing or breakage of instrument. The postoperative JOA scores was 13.5-16.9 (average 15.8). Conclusions Allantoaxial pedicle screw fixation has advantages of intraoperative reduction, reliable fixation and high fusion rate and can be used as an effective method for extension-type odontoid fracture combined with at-lantoaxial subluxation.

Effect of autocontrol micromotion intramedullary interlocking nail on fracture healing： an experimental study

Objective: To investigate the effect of autocontrol micromotion locking nail ( AMLN ) on experimental fracture healing and its mechanism. Methods: 16 goats undergoing both sides of transverse osteotomy of the femoral shafts were fixed intramedullary with AMLN and Gross-Kempf (GK) nail, respectively. The follow-up time was 7, 14, 28 and 56 days. Roentgenographic, biomechanical, histological, scanning electromicroscopic and biochemical analyses were done. Results: (1) The strength of anticompression, antiflexion and antitorsion in the fractural end in the AMLN-fixed group was higher than that of GK nail-fixed group; whereas, the rate of stress shelter in the fractured end decreased significantly (P<0.01). (2) The content of the total collagen, insoluble collagen, calcium and phosphate in the AMLN-fixed group was higher than that in the GK nail-fixed group (P<0.05). (3) Histological observation and quantitative analysis of calluses revealed that AMLN could promote the growth of bridge calluses and periosteum calluses. Hence the facture healing and remolding process achieved early, which was much better than traditional GK nail fixation. (P<0.05). (4) 7-14 days postoperation, the calluses of AMLN-fixed group was flourish and camellarly arranged and the collagen fibril formed constantly in the absorption lacuna of bone trabecula. 28-56 days postoperation, the collagen fibril was flourish around the absorption lacuna and was parallel to the bone's longitudinal axis. Active bony absorption and formation were seen, so was remolding and rebuilding. Haversian system was intact and the bony structural net was very tenacious because of the deposition of calcium salt. None of the above findings was observed in the GK nailfixed group. Conclusions: The design of AMLN accords well with the plastic fixation theory. As the geometry ametabolic system constituted by the intramedullary fixation instruments and the proximal and distal end of the fracture is very firm and stable, the disturbance to the physical stress distributed in the fractural end is light. The generation and conduct of the intermittent physical stress between the fractural parts could reach the balance between stress conduct and stress protection. The feature that the healing and remolding take place at the same time speeds up the fractural healing process.
