Purpose: This study presents radiographic and laboratory analysis and comparison of bone resorption rate of grafted endochondral bone and intramembranous bone on the aspect of height and volumetric change. Patients and Methods: 18 partially edentulous patients who needed alveolar ridge augmentation for implant placement during the years 2002 to 2004 were selected for this study. Group A consisted of 5 males & 3 females who were treated with intraoral(intramembranous) bone and Group B consisted of 8 males & 2 females who were treated with iliac(endochondral) bone. Non-standard periapical X-ray was taken at day 1, 2 month, 4 months, 8 months after the surgery. Resorption rate of grafted bone were measured on these X-rays and compared. Also we calculated volume of grafted bone with models which was fabricated at 1.5 months, 6 months. Results: There was bone resorption in both groups. Group B showed more bone resorption than Group A. In Group A, the resorption rate according to the radiographic measurements was 9.81 %, and resorption rate according to volumetric measurement was 16.5 %. In group B, the resorption rate according to the radiographic measurements was 15.9 %, and resorption rate according to volumetric measurement was 30.6 %. Significant difference is on radiographic resorption of post-op 2, 4, 8 months on two groups (P < 0.05). Also significant difference is on volume resorption on two groups (P < 0.05). Conclusion: We found that more bone resorption occurred with iliac(endochondral) bone and when we use intraoral bone, that bone can maintain their vitality for alveolar ridge augmentation.

Leriche 증후군 환자에서 병변이 신동맥 상방까지 진행된 양상을 보일 경우, 직접적인 대동맥-대퇴동맥 우회술이 불가능 할 수 있어 현재까지 비해부학적 우회술 등이 많이 행해지고 있다. 그러나 장기간의 혈관 개통율 측면에서 볼 때 그리 매우 좋은 결과를 보이지 않고 있어, 여러 가지 수술 방법이 시도되고 있다. 통증으로 인해 보행에 제약을 받고 있던 48세 Leriche 증후군 환자에서 14 mm 인조혈관과 14-7-7 mm Y자형 인조혈관을 이용하여 흉부하행대동맥-양측 대퇴동맥 우회술을 시행하였다. 수술은 좌측 후측방 개흉술, 개복술 및 양측 대퇴부위 절개를 이용하여 흉부 하행 대동맥 및 대퇴동맥에 측단문합으로 인조혈관을 연결하였고, 두 인조혈관을 단단문합하여 수술을 진행하였다. 수술 후 환자는 별다른 문제없이 회복하여 퇴원하였다. 퇴원 후 6개월째 경과 양호한 상태로 외래 통해 관찰 중이다. 흉부하행대동맥-양측 대퇴동맥 우회술은 직접적인 대동맥-대퇴동맥 우회술이 어려운 경우 충분히 고려해 볼 수 있는 방법으로 생각된다.

Objective: The authors reviewed clinical and radiological outcomes in patients with three column injury of the cervical spine who had undergone posterior cervical fixation using Nitinol shape memory alloy loop in the anterior-posterior combined approach. Materials: Nine patients were surgically treated with anterior cervical fusion using an iliac bone graft and dynamic plate-screw system, and the posterior cervical fixation using Nitinol shape memory loop ($Davydov^{TM}$) at the same time. A retrospective review was performed. Clinical outcomes were assessed using the Frankel grading method. We reviewed the radiological parameters such as bony fusion rate, height of iliac bone graft strut, graft subsidence, cervical lordotic angle, and instrument related complication. Results: Single-level fusion was performed in five patients, and two-level fusion in four. Solid bone fusion was presented in all cases after surgery. The mean height of graft strut was significantly decreased from $20.46{\pm}9.97mm$ at immediate postoperative state to $18.87{\pm}8.60mm$ at the final follow-up period (p<0.05). The mean cervical lordotic angle decreased from $13.83{\pm}11.84^{\circ}$ to $11.37{\pm}6.03^{\circ}$ at the immediate postoperative state but then, increased to $24.39{\pm}9.83^{\circ}$ at the final follow-up period (p<0.05). There were no instrument related complications. Conclusion: We suggest that the posterior cervical fixation using Nitinol shape memory alloy loop may be a simple and useful method, and be one of treatment options in anterior-posterior combined approach for the patients with the three column injury of the cervical spine.

Objectives : Thoracolumbar burst fractures(TBLF) result in not only compressive deformity of vertebral body but also spinal cord compression by bony fragments. Many thoracolumbar burst fractures demand both anterior decompression and intervertebral fusion. Most of spinal surgeons use anterior instrumentation for anteior intervertebral bony fusion. The use of Z-plate has been increased recently, however there has been only a few reports regarding its clinical long-term strength. We studied nineteen patients with TBLF to find out the long-term stability of Z-plate. Methods : We have operated 19 patients from March 1996 to August 1998. They were treated with anterior decompression through either a transthoracic, retroperitoneal extrapleural or retroperitoneal approach. Retropulsed bony fragments were removed completely by corpectomy. Iliac bone graft was used for interbody fusion in all of the cases. They were evaluated by plain X-ray films including flexion and extention lateral films. Cobbs angle was used to evaluate kyphotic and lateral wedging deformity. Results : Burst fractured sites were T11 in two, three T12, nine L1, and five L2. Mean follow-up duration was fifteen months. Preoperative average kyphotic angle was 23.7 degree. Immediate postoperative kyphotic angle was 10.2 degree. Follow-up resluts of average kyphotic angles revealed 14 degrees. Four patients(21%), including two spinal 3-column injury, showed increasement of kyphotic angle more than 5 degree or breakage of intrumentation. Two patients showed the difference of kyphotic angle more than 3 degree. Five patients(26%) revealed lateral wedging deformity more than 3 degrees. Postoperative complications were two meralgia parestheticas, one pulmonary atelectasis and two donor site infections. Four of the eight patients, who initially showed incomplete spinal cord deficits, were nerologically improved by Frankel's grade. Conclusion : Z-plate fixation and iliac bone graft after anterior decompression in thoracolumbar burst fractures is a safe and easy method. Immediate postoperative results revealed excellent correction of posttraumatic kyphosis, but long-term follow-up evalution showed insufficient strength. Therefore we believe that use of Z-plate should be carefully decided, especially in the case of large lumbar fracture or 3-column injury.

Objectives This study analyzed the correlation between body parameters measured using X-ray and Chuna posture analysis system to determine their clinical value in diagnosing and evaluating skeletomuscular diseases. Methods X-ray and Chuna posture analysis system were performed for 105 patients to measure physical characteristics such as Interacromial angle, Pelvic obliquity angle, Structural leg length discrepancy (SLLD), Midpatella-midtalus angle (MMA) and Q-angle, Anterior head translation (AHT), Anterior superior iliac spine to posterior superior iliac spine angle (ASIS-PSIS angle), Interscapular angle, Scoliotic angle and Cobb's angle. Statistical analysis using statistical analysis techniques and Pearson correlation coefficients was performed to assess the body parameters obtained by X-ray and Chuna posture analysis system. Results Significant correlations were observed between the values for Interacromial angle, Pelvic obliquity angle, SLLD, MMA and Q-angle, AHT, ASIS-PSIS angle, Interscapular angle, Scoliotic angle and Cobb's angle obtained by X-ray and Chuna posture analysis system. Significant correlations were also observed between right MMA and left Q-angle as well as between left MMA and right Q-angle. Conclusions Chuna posture analysis system can be used instead of X-ray measure body parameters and perform posture analysis in clinical practice. This study's findings are expected to serve as a basis for further research on the clinical application of Chuna posture analysis system.

Objectives: The requirement for overnight hospital stay should be considered preoperatively according to patient-related factors, type of surgery, and anesthetic management plan. In this study, we aimed to define the major factors that influence consideration of overnight hospital stay in patients undergoing oral and maxillofacial (OMF) surgery in an operating room (OR) of a dental hospital in an outpatient setting. Materials and Methods: The records of patients who underwent oral procedures under general anesthesia between 2014-2017 were reviewed. Results: A total of 821 patients underwent oral procedures under general anesthesia; 631 of them underwent OMF surgery in the OR of a dental hospital, and 174 of these patients were hospitalized for overnight stay. There was no significant difference in the number of patients with comorbidities between the outpatient and hospitalized patient groups (P=0.389). The duration of surgery was longer in the hospitalized patient group (105.25±57.48 vs 189.62±82.03 minutes; P<0.001). Double-jaw (n=15; 310.00±54.21 minutes) and iliac crest grafting surgeries (n=59; 211.86±61.02 minutes) had the longest durations. Patients who underwent iliac crest grafting had the highest rates of hospitalization (79%). The overall recovery period was longer in outpatients (119.40±41.60 vs 149.83±52.04; P<0.001). Conclusion: Duration of surgery was the main determinant in considering whether a patient required overnight hospital stay. However, patients with an American Society of Anesthesiology physical status score <3 may be scheduled for OMF surgery in the OR of a dental hospital in an outpatient setting regardless of duration of surgery if overnight hospital stay is planned or an extended recovery period is provided until patients meet the discharge criteria.
