목적: Sanders 4형 관절내 종골 골절에 대한 관혈적 정복술 및 내고정술과 일차성 거골하 관절 유합술의 임상적 결과를 분석하고자 하였다. 대상 및 방법: 2003년 3월부터 2013년 11월까지 Sanders 4형 종골 골절로 진단되어 관혈적 정복술 및 내고정술을 시행한 11예와 일차성 거골하 관절 유합술을 시행한 11예를 비교 분석하였다. 평균 추시 기간은 34.6개월(18-72개월)이었다. 술 후 6, 12개월 및 최종 추시 시 American Orthopedic Foot and Ankle Society's ankle-hindfoot scale (AOFAS) 점수 및 visual analogue scale pain (VAS) 통증 점수를 측정하였고 환자 만족도, 직장 복귀 여부 및 술 후 합병증을 조사하였다. 결과: 최종 추시 시 AOFAS 점수 및 VAS 점수는 양 군 간 의미 있는 차이는 보이지 않았으나(p>0.05) 일차성 거골하 관절 유합술을 시행한 군에서 환자의 만족도가 높았다(p=0.008). 관혈적 정복술군에서 증상을 동반한 거골하 관절염으로 이차성 거골하 관절 유합술을 5예(45.5%)에서 시행하였다. 결론: 양 군 간 임상적으로 의미 있는 결과의 차이는 보이지 않았으나 일차성 거골하 관절 유합술이 술 후 만족도가 높아 빠른 일상 복귀를 필요로 하는 환자 혹은 2차 수술이 불가피할 것으로 예상되는 경우 일차성 거골하 관절 유합술을 고려해 볼 수 있을 것으로 생각된다.

Purpose: The optimal management for ankle fracture in elderly patients remains controversial. This study was undertaken to review the results of surgical treatment of ankle fracture in the elderly and to compare with other studies. Materials and Methods: The participants in this study were 33 patients over the age of 65(average 71.5 years) who underwent surgical treatment of ankle fracture from January 2004 to December 2011. The study was a retrospective review of outcomes after open reduction and internal fixation (ORIF) of ankle fractures. To measure the clinical outcomes, we assessed postoperative complications, the pre- and post-operative mobility status, fracture union status, the time of fracture union and the AOFAS (American Orthopaedic Foot and Ankle Society) Ankle-Hindfoot scale. The level of patient satisfaction was also identified. Results: Delayed wound healing occurred in three patients(9.1%) but their wounds healed with repeated dressings without additional surgical treatment. Malunion occurred in one patient(3%). One patient(3%) had postoperative infection but healed with antibiotic treatment. 24 patients(96%) returned to preoperative mobility status. VAS score was lower than 2 in all patients. Bone union occurred with the 3.8 months (average months) after the surgery in all patients. Average AOFAS score was 87.4 and these were similar results as other studies of young patients. All patients were satisfied with surgical outcomes according to interviews. Conclusion: Surgical treatment of ankle fractures in the elderly can carry a significant risk of delayed wound healing and infection but incidence is relatively low. Internal fixation of ankle fractures in the elderly can be undertaken safely and the majority of patients can expect good outcome.

The purpose of this study Is to assess the retained range of motion[RROM] of the foot after arthrodesis of the ankle joint, which might help designing the angle of arthrodesis. We reviewed the results including the RROM in 14 cases of ankle arthrodesis. Underlying causes included trauma group(six posttraumatic arthritis) and disease group(three osteoarthritis, three Charcot joints, one chronic synovitis and one pyogenic arthritis). We measured the RROM on the lateral roentgenograms of the ankle in full dorsiflexion and plantarflexion, The results were assessed by the AOFAS hindfoot scale[score]. The RROM in sagittal plane was $23.4{\pm}5.3$ degrees and the score was 71.5 points on average. The RROM and the score were $26.8^{\circ}{\pm}2.1$, 81.2 points respectively in trauma group and $20.8^{\circ}{\pm}5.6$, 64.3 points in disease group; $26.6^{\circ}{\pm}2.3$, 83.4 points in cases younger than 40 years of age and $21.6^{\circ}{\pm}5.7$, 64.9 points in the older. The mean score was 77.3 points in cases whose RROM were $24^{\circ}$ or more and 61 points in cases of less RROM; 69.6 and 73.4 points in cases with and without adjacent degenerative arthritis respectively. The score was 69.7, 73.3 and 71.5 points in cases whose angle of arthrodesis was in dorsiflexion, neutral, plantarflexion respectively. In conclusion, after ankle arthrodesis RROM of the foot was $23.4^{\circ}$, and the more the RROM, the higher the score. In cases with sufficient amount of RROM, the angle of fusion on sagittal plane might not influence the result significantly.

Purpose: We evaluated the correlation of postoperative clinical outcomes and radiologic findings using computed tomography and simple X-ray in intra-articular calcaneal fractures. Materials and Methods: The current study is based on 41 feet, 38 patients with displaced intra-articular fracture who underwent surgical treatment with at least one year of follow-up. Evaluation of clinical outcome included American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS) score, and subjective satisfaction. A simple X-ray was used in evaluation of preoperative and postoperative Gissane angle, B${\ddot{O}}$hler angle, and calcaneal fracture width. Computed tomography scan was performed for evaluation of preoperative and postoperative articular step-off and articular gap in all cases. Finally, we evaluated the correlation of the postoperative clinical outcomes and radiologic findings based on the measurement. Results: The average postoperative AOFAS score and VAS score was $84.1{\pm}8.5$ and $2.2{\pm}2.2$. Subjective satisfaction was excellent in 15 cases, good in 19 cases, and fair in seven cases. The average B${\ddot{O}}$hler angle was restored from $11.1^{\circ}$ to $24.7^{\circ}$(p<0.05), Gissane angle was changed from $121.0^{\circ}$ to $119.0^{\circ}$ (p>0.05), and the average width was restored from 45.8 to 35.0 mm (p<0.05). The average articular step-off and gap were decreased from 6.3 to 2.0 mm and from 11.1 to 4.6 mm, respectively (p<0.05). No significant correlations were observed between the clinical outcome and Gissane angle, B${\ddot{O}}$hler angle, and width, and there was no significant correlation between the clinical outcome and Sanders classification. However, postoperative articular step-off showed correlation with VAS and AOFAS score and articular gap showed correlation with VAS score. Conclusion: The clinical outcome did not show correlation with B${\ddot{O}}$hler angle and Gissane angle but did show correlation with anatomical reduction of the posterior facet joint.

Purpose: This study was designed to investigate the usefulness of extensile lateral approach for accurate reduction and rigid internal fixation in comminuted intraarticular fractures of calcaneus. Materials and Methods: From October 2002 to May 2007, we managed 55 patients (62 cases) with open reduction and internal fixation using extensile lateral approach. Among these, 38 patients (43 cases) who underwent preoperative and postoperative CT scan were enrolled. All patients were evaluated over 24 months after surgery. Bohler angle and Gissane angle on plain X-ray, displacement and step-off of articular surface of calcaneus on CT scan were measured and we compared the difference between preoperative and postoperative value of them. Clinical results were assessed by using AOFAS Ankle-Hindfoot Scale. Results: The average Bohler angle was restored from $6.8^{\circ}$ to $23.5^{\circ}$ and Gissane angle was improved from $116.4^{\circ}$ to $113.5^{\circ}$ after operation. The average distance of displacement was restored from 4.2 mm to 1.4 mm and step-off of articular surface was recovered from 5.1 mm to 1.3 mm. Clinical results were excellent in 17 cases, good in 18 cases, fair in 3 cases, and poor in 5 cases. 10 cases developed postoperative complications such as skin necrosis, heel pain, limitation of motion of ankle and subtalar arthritis. Conclusion: The extensile lateral approach is valuable for the comminuted intraarticular fractures of calcaneus that enables accurate anatomical reduction and rigid internal fixation by providing direct exposure of subtalar joint.

Purpose: To evaluate the clinical and radiological results of tibio-talo-calcaneal arthrodesis using ipsilateral distal fibula buttress which had advantages of extended operative field and release of contracted soft tissue. Materials and Methods: We retrospectively reviewed 4 postraumatic compartment syndrome, 2 residual poliomyelitis, 1 posttraumatic osteoarthritis with subtalar joint infection and 1 posttarumatic sciatic nerve palsy patients who underwent a tibio-talo-calcaneal arthrodesis from April, 1996 to March, 2002. Each of the cases was notable for a severe rigid equinovarus, persistent pus drainage of calcaneal area and paralytic foot. The mean duration of follow up was 18 months (range, $13{\sim}42$ months). The pain, function and alignment were evaluated by the modified ankle hindfoot scale of the American Orthopaedic Foot and Ankle Society (AOFAS) and patients satisfaction clinically. The radiological union were evaluated by plain AP and lateral radiographs. Results: The AOFAS score improved from 58 points (range, $47{\sim}78$) preoperatively to 82 (range, $60{\sim}89$) postoperatively. Patents satisfaction checked at 12 months after operation had favorable results (excellent and good 80%). Union rate was 100% radiographically and the mean duration of union was 12.5 weeks (range $8{\sim}22$ weeks). There was 2 cases of superficial pin tract infection and one protrusion of screw. Conclusion: Tibio-talo-calcaneal arthrodesis using ipsilateral distal fibula buttress was good modality of arthrodesis which provides wide operative field and release of contracted soft tissue in some cases of contracted foot.

Purpose: This study was performed to evaluate the clinical outcomes of operative treatment using porous hydroxyapatite for intraarticular calcaneal fracture of joint depression type. Materials and Methods: Twenty patients with intraarticular calcaneal fracture were followed up for more than 1 year. The period to union was calculated to evaluate the osteoconductivity of porous hydroxyapatite used as bone graft substitute. The measurement of Bohler angle, Gissane angle and the degree of articular surface depression was performed through preoperative and postoperative radiographs. The clinical evaluation was performed according to hindfoot score of the American Orthopaedic Foot and Ankle Society (AOFAS) and scale of the Creighton-Nebraska health foundation (CNHF). Results: Bohler angle and Gissane angle had improved significantly from preoperative average $10.4^{\circ}$, $117.8^{\circ}$ to average $22.6^{\circ}$, $113.5^{\circ}$ immediate postoperatively, and had maintained to average $21.2^{\circ}$ and $114.4^{\circ}$ at the last follow-up. The degree of articular surface depression had improved significantly from preoperative average 4.8 mm to 1.5 mm at the last follow-up. All cases achieved bone union, and the interval to union was average 12.8 weeks. AOFAS score was average 85.2 points at last follow-up. There were 7 excellent, 10 good, and 3 fair results according to the CNHF scale. Therefore, 17 cases (85%) achieved satisfactory results. Conclusion: Plate fixation using porous hydroxyapatite seems to be one of effective treatment methods for intraarticular calcaneal fracture of joint depression type, because of supporting the reduction of subtalar articulation by augmenting bony defect and facilitating bone formation. Further evaluation about long-term radiological changes and histological analysis on hydroxyapatite implantation site should be required.

Purpose: This study was performed to evaluate the clinical outcomes of operative treatment using mini-open sinus tarsi approach for displaced intraarticular calcaneal fractures. Materials and Methods: We studied 18 cases (16 patients) of intraarticular calcaneal fractures who were treated with sinus tarsi approach by same surgeon. The mean age of patients was 44.8 years, and mean follow-up period was 17.2 months. The measurement of B$\ddot{o}$hler angle, Gissane angle, the degree of articular surface depression, and the period to union were performed through preoperative and postoperative radiographs. The clinical evaluation was performed according to hindfoot score of the American Orthopaedic Foot and Ankle Society (AOFAS) and scale of the Creighton-Nebraska health foundation (CNHF). Results: B$\ddot{o}$hler angle and Gissane angle had improved significantly from preoperative average $9.8^{\circ}$, $117.6^{\circ}$to average $22.4^{\circ}$, $113.4^{\circ}$ immediate postoperatively, and had maintained to average $21.8^{\circ}$and $114.2^{\circ}$ at the last follow-up. The degree of articular surface depression had improved significantly from preoperative average 5.2 mm to 1.2 mm at the last follow-up. All cases achieved bone union, and the period to union was average 10.5 weeks. AOFAS score was average 86.2 points at the last follow-up. There were 7 excellent, 9 good, and 2 fair results according to the CNHF scale. Therefore, 16 cases (88.8%) achieved satisfactory results. Conclusion: The minimally invasive sinus tarsi approach using headless compression screw seems to be an effective surgical method for displaced intraarticular calcaneal fractures, because of the possibility of accurate restoration of articular surface and the low risk of postoperative soft tissue complications.
