전 세계적으로 노인 인구는 급증하는 추세이며 노인 척추 변형 환자에 대한 변형 교정 수술도 점점 증가하고 있다. 그러나 노인 환자들을 대상으로 척추 변형 교정 수술 시 합병증을 줄이기 위해 고려해야 할 사항들, 그리고 수술 후 좋은 임상적인 결과를 예측하기 위한 객관적인 인자들에 대해 아직 많은 논의가 되지 않았다. 노인 척추 변형 환자에서 수술 전 고려해야 될 사항으로 Cumulative Illness Rating Scale for Geriatrics 및 Charlson Comorbidity Index scores 등의 지표를 이용하여 내과적 동반 질환을 확인해야 한다. 이들 지표는 술 후 합병증의 발생률과 연관이 있으며 수술 전 내과적인 질환을 조절하여 이 지표 수치를 낮춘 이후 수술을 시행할 경우 합병증을 줄일 수 있다. 두 번째, 수술 전 골밀도 검사를 시행하여 골다공증의 정도를 확인해야 한다. 심한 골다공증이 동반된 노인 척추 변형 환자의 경우 기기술과 관련된 합병증을 줄이기 위한 여러 가지 수술적인 기법들이 알려져 있으며 수술 전 골형성 유도제를 사용하여 골밀도를 교정하는 방법도 시도해볼 수 있다. 세 번째, 전 신체 시상학 정렬을 고려해야 한다. 노인 척추 변형 환자에서 고관절, 슬관절 등의 하지 관절의 퇴행성 변화와 변형을 동반하고 있는 경우가 흔하며 또한 척추의 변형이 보상작용으로 하지 관절의 변형을 일으키기도 한다. 최근 전 신체 시상학 정렬이 이전 사용되었던 척추나 골반에 국한된 지표보다 임상적인 상태를 더 잘 예측할 수 있는 것으로 보고되어 변형 교정 수술 시 전 신체 시상학 정렬을 고려하여야 하겠다. 결론으로 노인 척추 변형 환자에서 변형 교정 수술을 시행할 경우 내과적인 동반 질환, 골다공증의 정도를 확인하여 합병증을 줄이기 위해 수술 전 미리 교정하는 것이 필요하다. 또한 교정 수술 시 골반이나 척추에 국한된 지표에 비하여 임상적인 상태를 더 잘 예측할 수 있는 전 신체 시상학 정렬을 고려해야 한다.

The traffic accident was one of most common cause for the facial bone fracture. When it involved the midfacial structures, the nasal bone fracture was usually shown. If the reduction was not done in time, it would result in facial deformity. Simple case could be corrected by simple rhinoplasty. However, severe cases would require more invasive technique. We used triangular osteotomy included the nasal bones, the vomer, and the medial wall of maxilla for the correction of post-traumatic nasal deformity and reported the result with the review of literatures.

Objectives : The purpose of this study was to evaluate surgical outcomes and complications of spinal deformity associated with neurofibromatosis type-1 (NF-1). Methods : From 2012 to 2018, patients suffering from spinal deformity associated with NF-1 who underwent surgical correction were identified. Demographic data and radiographic measures were retrospectively reviewed. Pre- and postoperative whole spine radiograph images were used to determine both coronal and sagittal Cobb angles. All of patients underwent 3-dimentional computed tomographic scan and magnetic resonance imaging scan to confirm dystrophic features. For evaluation of clinical outcomes, we surveyed the pre- and postoperative scoliosis research society-22r (SRS-22r) score. Results : Seven patients with spinal deformity associated with NF-1 were enrolled in this study. The mean age of patients was 29.5±1.2 years old. The mean follow-up period was 2.8±1.4 years. The apex of the deformity was located in cervicothoracic (n=1), thoracic (n=4), and lumbar region (n=2). Most patients have poor bone quality and decreased bone mineral density with average T-score of -3.5±1.0. All patients underwent surgical correction via posterior approach. The pre- and postoperative mean coronal and sagittal Cobb angle was 61.6±22.6° and 34.6±38.1°, 56.8±18.5° and 40.2±9.1°, respectively. Mean correction rate of coronal and sagittal angle was 44.7% and 23.1%. Ultimate follow-up SRS-22r score (average score, 3.9±0.4) improved comparing to preoperative score (average score, 3.3±0.9). Only one patient received revision surgery due to rod fracture. No serious complication occurred, such as neurological deficit, and viscerovascular injury. Conclusion : The surgical correction of patients having spinal deformity associated with NF-1 is challenging, however the radiographic and clinical outcomes are satisfactory. The all posterior approach can be a safe and effective surgical option for patients having dystrophic curves associated with NF-1.

Objective : The maintenance of the correction of kyphotic deformity is one of the difficult problem in tuberculous spondylitis after anterior debriment and fusion with tricortical bone graft. The goal of this study is to find out the efficacy of titanium mesh cage impacted with autogenous bone chip in tuberculous spondylitis treated with anterior intervertebral fusion. Materials and Method : Twelve patients were treated with anterior intervertebral fusion using titanium mesh cage for tuberculous spondylitis from January 1996 to June 1999. We analized the changes in the correction of kyphotic deformity, changes of ESR and CRP, fusion state and recurrence after anterior intervertebral fusion with titanium mesh cage. Results : Clinical symptoms were improved in all twelve patients without any neurologic complications. The mean kyphotic angle corrected was 7.3 degrees immediately after operation, but the loss of correction of kyphotic angle was 2.2 degrees after 3 months and 2.6 degrees after 6 months. We found that the loss of correction of kyphotic deformity occurred mainly within the first 3 months after surgery. Only one patient, suffered from acute hepatic failure after first operation and had an insufficient anti-tuberculous medication therapy, showed recurrence of tuberculous spondylitis after 6 months. The patient underwent a second operation with posterior fixation procedure with good outcome. The changes of ESR and CRP were not specifically important factor to reveal recurrence of tuberculosis of the spine in our series. Conclusion : The surgical procedure of tuberculous spondylitis using titanium mesh cage with bone chip seems to be an effective procedure to minimize loss of the correction of kyphotic deformity without any aggravating inflammatory change and recurrence with titanium mesh cage, when sufficient debridement and anti-tuberculous chemotherapy are achieved.

Purpose: A lot of surgical techniques were tried to correct extension lag of distal interphalangeal joint. Spiral oblique retinacular ligament reconstruction is the one of correction techniques. Methods: From January 2004 to January 2005, a total of 13 extension lag of distal interphalangeal joint corrections were performed using spiral oblique retinacular ligament reconstruction for 11 patients. After dorsal incision exposing from base of distal phalanx to proximal phalanx, the new ligament(half of lateral band or graft tendon) lies distally at the dorsum of the distal phalanx and passes volarly and proximally along the side of the middle phalanx and anterior and obliquely across the front of the proximal interphalangeal joint to the opposite side of the digit at the proximal phalanx. Results: 5 of 6 mallet finger deformities and 7 swan neck deformities were corrected, which were both extension lag of distal interphalangeal joint and hyperextension of proximal interphalangeal joint. Conclusion: As a result, spiral oblique retinacular ligament reconstruction is an effective and recommendable method for correction of mallet finger deformity and swan neck deformity.

Purpose: Most unilateral secondary cleft lip nose deformities have depressed nostril base and sill on the cleft side. To obtain a symmetric nose, correction of the recession on nostril is critical. The authors have worked out effective methods to elevate the nostril of the cleft side according to the extent of the depression. Methods: A total of 115 unilateral secondary cleft lip nose deformity patients with nostril depression were evaluated. Data were acquired from patients' charts and photography with special reference to the height difference of the nostrils between the cleft side and the non - cleft side. Patients were divided into three groups based on the difference and operated with various techniques : (1) mild degree(< 1 mm) with graft, (2) moderate degree(1 ~ 3 mm) with C - flap or suspension suture of septal cartilage (3) severe degree(> 3 mm) with graft, C - flap and suspension suture. Follow - up period averaged 21.3 months. Results: Forty - six patients(40 percent) were in mild group, and forty - two(37 percent) were in moderate. In twenty - seven patients(23 percent), nostril recession was more than 3 mm. The elevated nostril base and sill were maintained without height alteration during follow - up. Conclusion: The symmetry of the nostril base, especially projection of nostril sill influences successful correction of unilateral cleft lip nose deformity. Our tolerable techniques can be applied to most deformities with nostril depression and can present a new guideline.

Purpose: In this study, we tried to develop the technique of osteotomy for hallux valgus. The new modified technique of osteotomy was accomplished with even more greater stability, accurate correction of the deformity and more effective than 'chevron' osteotomy in terms of correction of the deformity. Materials and Methods: Between March 1998 and December 2001, 55 cases of new modified osteotomy for hallux valgus were performed for 39 patients, 16 of whom underwent operation of both feet. Operations were made for 34 women and 5 men whose average age was 46 years old (range, $20{\sim}71$ years). Average follow up period was three years (range, $2{\sim}5$ years), and during the follow up, the patients underwent physical examination and assessment with use of the American Orthpaedic Foot and Ankle Society's hallux-metatarso-phalangealinterphalangeal scale and standard foot radiographic measurements. Results: 37 patients (53 cases) out of 39 patients (55 cases) had no pain, good cosmesis, and all of the patients were satisfied with the results of the operation. Two had occasional mild discomfort. The average score according to the hallux-metatarso-phallangeal-interphalangeal scale was 93.2 points (range, $78{\sim}100$ points). The average preoperative intermetatarsal angle was $14.4^{\circ}$, which was decreased to $7.9^{\circ}$ after the osteotomy with an average correction of $6.5^{\circ}$ and The average preoperative hallux valgus angle was $34.1^{\circ}$, which was decreased to $11.1^{\circ}$ after the osteotomy with an average correction of $23^{\circ}$. This new modified technique would prevent the angulation or shortening at the osteotomy site and it was also even more stable at osteotomy site, and could do even more effective and accurate correction of the deformity than conventional Chevron osteotomy. Conclusion: New modified chevron osteotomy for the treatment of symptomatic hallux valgus was done in 55 cases, and the results were satisfactory in all cases. This method was more stable at the osteotomy site than conventional Chevron osteotomy and was also possible to do more accurate and more effective correction of the deformity. It was also easy to control the distal fragment of first metatarsal bone.
