Background: The purpose of this study was to compare clinical and radiological results of arthrodesis performed by the anterior approach and by the transfibular approach in ankle osteoarthritis. Methods: Sixty patients underwent open arthrodesis (38 by the anterior approach and 22 by the transfibular approach). The visual analogue scale score and the American Orthopedic Foot and Ankle Society (AOFAS) score were examined clinically, and radiological examination was performed on the alignment of the lower extremity and bone union. Results: Both groups showed significant improvement in AOFAS score (from 39.8 to 58.3 in the anterior approach group and from 44.5 to 60.7 in the transfibular approach group). There was no significant difference in AOFAS score at the last follow-up in both groups. The time to fusion was 13.5 weeks in the anterior approach group and 11.8 weeks in the transfibular approach group. Nonunion occurred in four cases in the anterior approach group and in one case in the transfibular approach group. Conclusions: Ankle arthrodesis by the anterior approach and the transfibular approach showed comparably good clinical results.

Purpose: The purpose of the study was to investigate five cases with chronic Achilles tendon rupture that occurred after steroid injections. Materials and Methods: In our hospital, we experienced five cases of chronic Achilles tendon rupture from September 2010 to March 2012. All patients had got steroid injection for Achilles tendinitis at the other hospitals, and their heel pain was aggravated when they visited our outpatient department. After treatment, signs and symptoms of Achilles tendon rupture were developed and the diagnosis was confirmed by ultrasonography or magnetic resonance imaging (MRI). Surgical treatment was done for Achilles tendon rupture. Results: There was difference between intra-operative findings of Achilles tendon rupture and usual chronic Achilles tendon rupture. Unlike usual findings of chronic Achilles tendon rupture whose scar tissue or tissue attenuation are found around the defect area of Achilles tendon, there were partial necrosis of tendon severe adhesion with surrounding tissue, extensive defect and longitudinal rupture on ruptured area. Also, severe inflammation of paratenon, granulation and fibrinoid deposit were found on biopsy findings in four cases. Conclusion: Based on review of data about relative risk and benefit of local corticosteroid injection to inflammatory lesion in Achilles tendon, it requires more attention to Achilles tendon rupture following local corticosteroid injection.

만성 재발성 다발성 골수염은 비감염성 염증성 골병변으로 주로 소아와 청소년에게 발생하는 질환이다. 임상적으로 모호한 골성 동통을 호소하며, 방사선학적 소견 및 조직학적 소견이 감염성 골수염과 유사하다. 또한 비교적 드문 질환으로서 다른 질환과의 감별이 어려워 종종 오진을 할 수 있다. 본원에서 11세 남아의 원위 경골 및 비골에 발생한 만성 재발성 골수염 1예를 경험하였기에 문헌 고찰과 함께 보고하고자 한다. Chronic recurrent multifocal osteomyelitis (CRMO) is a non-infectious inflammatory bone disease that occurs mainly in children and adolescents. The clinical presentation shows imprecise bone pain, while radiologic findings and histologic exam are similar to those of infectious osteomyelitis. It is a rare disease, which is difficult to distinguish from other diseases, therefore it could be misdiagnosed. We report on a case of CRMO on the distal tibia and fibula in an 11-year-old boy.

Purpose: This study examined the factors affecting the treatment of diabetes mellitus foot patients who had undergone a Syme amputation. Materials and Methods: This study included 17 patients diagnosed with a diabetes mellitus foot and who had undergone a Syme amputation from January 2010 to January 2014. Some of the risk factors (age, body mass index [BMI], disease duration, smoking, ankle brachial index [ABI], HbA1c, serum albumin, total lymphocyte, C-reactive protein [CRP], and serum creatine) that affect the successful Syme amputation were analyzed. Results: The healing rate of a Syme amputation was significantly higher when the lymphocyte count was above $1,500mm^3$ (p=0.029). The factors affecting the surgical outcome according to multivariate analysis were HbA1c and the BMI (p=0.014, p=0.013). Regarding reamputation, there was a significant difference with HbA1c, lymphocyte, and BMI (p=0.01, p=0.03, and p=0.01). No significant differences were observed with age, disease duration of diabetes mellitus, smoking, ABI, serum albumin, CRP, and serum creatine. Conclusion: The HbA1c level, BMI and total lymphocyte count are risk factors that must be considered for successful Syme amputation in patients with diabetic foot disease.

Osteochondroma, which is an osteocartilaginous exostosis, is essentially the most common primary bone tumor. These benign neoplasms are generally asymptomatic and have a relatively small potential for adverse effects. Calcaneal osteochondroma is rare, furthermore osteochondroma accompanying with gouty arthritis is very rare. Also, the subtalar joint is not a classic site of acute gout. In this report, we report the case of a patient who experienced an unusual calcaneal osteochondroma with undiagnosed gouty arthritis of the subtalar joint.

곽희철,김전교,김정한,노상명 대한정형외과학회 2015 Clinics in Orthopedic Surgery Vol.7 No.4

Background: To compare the effectiveness of intraoperative three-dimensional (3D) image and conventional two-dimensional (2D) fluoroscopic images, which are used in the treatment of acute calcaneal fractures. Methods: We retrospectively analyzed 40 patients who suffered calcaneal fracture and underwent surgery at Inje University Busan Paik Hospital. The patients were divided into two groups. Only 2D fluoroscopy was used to evaluate 20 patients of group 1. On the other hand, 3D fluoroscopy was performed on the remaining 20 patients of group 2; 3D fluoroscopy was performed on these patients after they were extensively evaluated by 2D fluoroscopy during surgery. We reviewed the radiographic and clinical outcomes of these patients, whose average follow-up period was 42.6 months. Results: In group 2, 3D fluoroscopy detected four cases (20%) of articular incongruence and screw misplacement. All these complicated cases were corrected during surgery. At the final follow-up session, the mean American Orthopedic Foot and Ankle Society (AOFAS) hind foot score was 78.3 (range, 65 to 95) in group 1 and 82.3 (range, 68 to 95) in group 2. Conclusions: Intraoperative 3D imaging of calcaneal fractures is considered to be useful in evaluating the congruence of joints and the placement of implants.

하동준,김전교,곽희철,장의찬,Ha, Dong-Jun,Kim, Jeon-Gyo,Gwak, Heui-Chul,Jang, Yue-Chan 대한족부족관절학회 2015 대한족부족관절학회지 Vol.19 No.4

Purpose: The purpose of this study is to retrospectively analyze the clinical results of screws and Kirschner wire (K-wire) fixation in patients with fracture dislocation of Lisfranc joint and the consequence of screw breakage. Materials and Methods: Sixty patients underwent Lisfranc joint open reduction and removal of internal fixators from January 2007 to December 2011. Forty-nine cases (81.7%) underwent operations with screw alone, and 11 cases (18.3%) underwent operations with both screws and K-wires. Type of internal fixators, duration of internal fixator removal, breakage of internal fixators and satisfaction with reduction were investigated. Additionally, American Orthopaedic Foot and Ankle Society (AOFAS) midfoot scales were analyzed. Results: The internal fixator was broken in 5 cases (8.3%). The average duration of instrument removal was 154 days in the non-broken screw group and 268.6 days in the broken screw group (p<0.05). The average AOFAS midfoot scale was 77.4 in the non-broken screw group and 74.2 in the broken screw group. The most commonly damaged portion was the first tarsometatarsal (Lisfranc) joint. Conclusion: Treatment with screws and K-wires was effective in patients with fracture dislocation of Lisfranc joint. The appropriate time for screw removal should be considered.

한국인 사체에서의 정상 종골의 실측: 예비보고

Purpose: The purpose of this report is to evaluate the measured values of normal Korean calcaneus by conduct of a cadaveric study. Materials and Methods: A total of 42 calcanei were obtained from Korean cadavers. A digital goniometer was used for measurement of B$\ddot{o}$hler's angle, Gissane angle, posterior facet articular inclination angle, and Fowler-Philip angle of calcaneus. A vernier caliper was used for measurement of the maximal antero-posterior length, maximal transverse width, and maximal height of calcaneus. Results: The average B$\ddot{o}$hler's angle, Gissane angle, posterior facet articular inclination angle, and Fowler-Philip angle was $32.3^{\circ}{\pm}5.0^{\circ}$, $114.4^{\circ}{\pm}8.2^{\circ}$, $61.2^{\circ}{\pm}4.4^{\circ}$, and $60.3^{\circ}{\pm}7.6^{\circ}$. The average maximal antero-posterior length, maximal transverse width, and maximal height of calcaneus was $74.2{\pm}3.0mm$, $43.0{\pm}4.0mm$, and $42.5{\pm}3.0mm$. Conclusion: The measured values of normal Korean calcaneus were lower than the values reported in the international literature. Therefore, development of appropriate instruments reflecting the anatomical characteristics of Koreans will be needed.
