ABSTRACT
[Objective]To provide quantitative data of atlantoaxial pedicle for its surgical screw internal fixation by imageology measurement and improve the success rate of the surgical treatment.[Method]The examinations ofCR,DRX,MRI and 64-row CT were performed in each patient preoperatively,and the atlantoaxial pedical screw entry points and screw entry angles were then measured by PACsee system.[Result]The atlas pedicle screw entry points were localized position which its distance to the left of the atlas pedicle midline was(19.93?1.32) mm,and to the right of the atlas pedicle midline was(19.16?1.30)mm.The screw entry angles to the inside of the atlas pedicle were localized position which its distance to the left of the atlas pedicle midline was(23.72?2.09)?,and to the right of the atlas pedicle midline was(23.35?1.91)?.The screw entry angle to the head of the atlas pedicle was(9.00?1.20)?.The axis pedicle screw entry points were localized position which its distance to the left of the axis pedicle midline was(13.14+0.82) mm,and to the right of the axis pedicle midline was(13.85?0.79)mm.The screw entry angles to inside of the axis pedicle were localized position which its distance to the left of the axis pedicle midline was(24.52?1.26)?,and to the right of the axis pedicle midline was(20.42?1.42)?,The screw entry angle to the head of the axis pedicle was(25?3)?.48 patients were taken treatment with atlantoaxial pedicle surgical screw intemal fixation.Among these patients,there were 35 males and 13 females with a mean age 43.60 years old(ranged 22 to 61 years old),22 patients with type II old odontoid fracture,12 patients with odontoid nonunion and 14 patients disruption of the transverse ligament.The x-ray and CT scans of all post-surgery patients could prove the atlas were completely reduced,axis odontoid fracture had good reduction and bony fusion were achieved after 10.6 months.The JOA evaluation standards showed 31 patients were excellent,14 patients were good,2 patients were fair and a patient was poor,excellent and good ratio was 93.57%.[Conclusion]The imageology measurement quantitative data of atlantoaxial pedicle could guide effectively the screw internal fixation surgery.
ABSTRACT
<p><b>OBJECTIVE</b>To introduce a method for repairing and restoring hand function of the patients suffering from large surface area burn with scarce normal skin for reconstruction.</p><p><b>METHODS</b>Seven patients (ten hands) were treated in our department from April 1994 to February 2001. The TBSA involved with second- or third-degree burns was 85%-96%. All the hands had severe scar contracture on the dorsum and lost most of their function. A scarred skin flap, based on the ulnar border of the hand was elevated integrally on the dorsum. A random-pattern abdominal flap at a less-scarred area was designed and elevated to cover the defect of the hand while the scarred skin flap of the hand was transferred to the donor site of the abdominal flap.</p><p><b>RESULTS</b>All patients were followed for 0.5 to 4 years postoperatively. The range of motion of the metacarpophalangeal joint and the space capacity of the first web were greatly improved. All patients regained self-care ability.</p><p><b>CONCLUSIONS</b>This method is simple and has satisfactory results. Under the circumstances where normal skin was not available for reconstruction, the function of the burned hand could be greatly improved by this method.</p>
