The fibrous dysplasia is a progressive and disabling condition that lead to deformity, especially weight bearing bones. The morbidity that is associated with the polyostotic fibrous dysplasia is the recurrent fracture and deformity. Various methods of treatment had been failed to control this problem. We used osteotomy and reconstruction nailing for polyostotic fibrous dysplasia occured in the proximal part of right femur with varus deformity and reconstruction nailing in left femur without osteotomy, and interlocking intramedullary nailing in right tibia to prevent pathologic fracture. These methods brought a good result of bone union and full weight bearing ambulation after 1 year and 6 month follow up. We think these methods are useful methods to control refracture and deformity, so we reported this case with bibliographic reviews.

Although first generation total ankle replacement (TAR) had high failure rates, recent investigations have reported good results of the newer generations of TAR due to advances in implant designs and techniques. Patient selection is critical to performing TAR to obtain promising outcomes and to decrease complication rate. As the current concepts of correcting the accompanying deformity have been established, TAR in moderate to severe varus deformity of the ankle result in favorable outcomes and indications for TAR are expanding. Correction of deformity and hindfoot fusion should be performed in conjunction with TAR if needed. If radiolucency around components or osteolysis is progressive during follow-up, CT should be carried out as a confirmative diagnostic method. TAR is an effective treatment modality alternative to ankle fusion. However, we should recognize that TAR is a demanding procedure, which requires accurate techniques, enough experience, and preoperative plan for a concomitant deformity.

The cavus foot is a deformity characterized by an elevated medial longitudinal arch and a hindfoot varus with plantarflexed 1st ray. The etiology of cavus foot is usually related to neuromuscular disease or idiopathic cause. Thorough clinical and radiographic evaluation is required for differentiating etiology of the cavus. Most cases of cavus foot are stable and slowly progressive deformities which can initially be managed with conservative treatment including orthoses and physical therapies. Determining whether the deformity is flexible or rigid, the apex of the deformity and any muscle imbalances in foot and ankle is important for achievement of an adequately balanced plantigrade foot. Treatment should include systematic preoperative planning for selection of appropriate procedures for maintaining a functional and flexible foot with combinations of soft-tissue release, osteotomy, tendon transfer, and arthrodesis.

The purpose of this study was to report the reliability and validity of oblique single-cut rotation osteotomy (OSCRO) in 3D-reconstructed canine bone models with femoral varus and torsional deformities. A healthy adult male beagle was recruited to create a 3D bone model, and this bone model was modified by using a 3D program. Fifteen bone models were constructed for this study. OSCRO simulation was performed in accordance with the plan after printing using a 3D printing machine. The anatomical lateral distal femoral angle (aLDFA), anteversion angle (AA), anatomical caudo-distal femoral angle (aCdDFA), mechanical caudo-distal femoral angle (mCdDFA) and pre- and postoperative bone length were calculated. There were no significant differences between the target values and postoperative values. In addition, the difference between pre- and postoperative bone length was small (p = 0.001). Our findings suggest that OSCRO could be an effective surgical option for MPL with bone deformities in small-breed dogs that often undergo conventional distal femoral osteotomy.

목적: 내측 반월상 연골 후각부 뿌리 파열의 치료에 있어서 수정된 Pull-Out 봉합술을 시행한 후 임상결과를 알아보고자 하였다. 대상 및 방법: 2006년 3월부터 2011년 2월까지 내측 반월상 연골 후각부 뿌리 파열의 치료에 있어서 수정된 Pull-Out 봉합술을 시행 받은 환자 74예 중 최소 12개월 이상 추시가 가능하였고 동반 질환이 있는 환자를 제외한 40예를 대상으로 하였다. 평균 연령은 49.5세 였다. 체중 부하 단순 방사선 사진에서 Kellgren과 Lawrence분류상 정상이나 초기 퇴행성 관절염(1-2군)이며, 체중 부하 방사선 하지 scanogram검사에서 역학적 축을 측정하였을 때 내반 변형이 없거나 5도 이내의 경도의 내반 변형 환자를 대상으로 하였으며, 연골 손상의 정도는 수술 중에 Outerbridge 분류를 사용하였으며, 임상적 결과는 Lysholm knee score를 사용하였다. 결과: 최종 추시상 Lysholm Knee Score는 술전 63.9점(범위; 53~78점)에서 술후 86.3점(범위; 72~94점)으로 향상 되었다 (p>0.05). 봉합술이 완전 실패한 경우는 40예 중 3예였다. 이는 현재 경과 관찰중에 있다. 관절연골 병변은 20예에서 내측 대퇴골 체중 부하 부위에 있었고, Outerbridge 분류상 1기 12예, 2기 5예, 3기 3예였다. 결론: 내측 반월상 연골 후각부 뿌리 파열의 치료에 있어서는 먼저 환자의 관절염이나 내반 변형 같은 동반 질환 여부를 가려내는 것이 중요하며, 경도의 관절염이나 내반 변형이 있는 40~60대 중년의 환자에서 수정된 Pull-Out 봉합술을 시행할 경우 비교적 양호한 임상적 결과를 얻을 수 있을 것으로 사료된다.

대퇴 근위부에 발생한 섬유성 골이형성증의 임상 증상으로는 동통, 파행, 하지 부등등이 유발되며 때로는 shepherd's crook 변형과 같은 심한 변형을 초래한다. 수술적 치료는 보존적 치료에 반응하지 않는 지속적인 동통이 있거나, 변형이 진행하는 경우에 시행하며 병변의 크기나 침범 부위, 변형 정도에 따라 다양한 치료가 시행되고 있다. 이에 저자들은 섬유성 골이 형성증으로 중증의 양측성 shepherd's crook 변형을 일으킨 환자 1례에 대해 전자부 교정 절골술과 Huckstep정을 이용하여 치료한 결과를 보고하고자 한다.

Purpose: Reconstructive surgeries for equinocavovarus foot deformities are quite variable, including hind-midfoot osteotomy or arthrodesis, soft tissue procedure, tendon transfers, etc. Comprehensive evaluation of the deformity and its etiology is mandatory for achievement of successful deformity correction. Few studies in this field have been reported. We report on the clinical and radiographic outcome of reconstruction for cavovarus foot deformities. Materials and Methods: The study is based on 16 feet with cavovarus foot deformities that underwent bony and soft tissue reconstructive surgery from 2004 to 2008. We evaluated the etiologies, varieties of surgical procedures performed, pain score, functional scores, and patient satisfaction and measured the radiographic parameters. Results: The average age at the time of surgery was 39.4 years old, with a male/female ratio of 9/4 and an average follow-up period of 23.9 months (range, 12~49 months). The etiologies of the cavovarus deformity were idiopathic 7 feet, residual poliomyelitis 5 feet, Charcot-Marie-Tooth disease 2 feet, and Guillain-Barre syndrome and hemiplegia due to cerebrovascular accident sequela 1 foot each. Lateral sliding calcaneal osteotomies were performed in 12 feet (75%), followed by Achilles tendon lengthening and plantar fascia release in 11 feet (69%), and first metatarsal dorsiflexion osteotomy/arthrodesis and tendon transfer in 10 feet (63%). Visual analogue scale pain score showed improvement, from an average of 4.2 to 0.5 points. American Orthopaedic Foot and Ankle Society ankle-hindfoot score showed significant improvement, from 47.8 to 90.0 points (p<0.05). All patients were satisfied. Ankle range of motion improved from $27.5^{\circ}$ to $46.7^{\circ}$. In radiographic measurements, calcaneal pitch angle improved from $19.1^{\circ}$ to $15.8^{\circ}$, Meary angle from $13.0^{\circ}$ to $9.3^{\circ}$, Hibb's angle from $44.3^{\circ}$ to $37.0^{\circ}$, and tibio-calcaneal axis angle from varus $17.5^{\circ}$ to varus $1.5^{\circ}$ Conclusion: We achieved successful correction of cavovarus foot deformities by performing appropriate comprehensive reconstructive procedures with improved functional, radiographic measures and high patient satisfaction.

The goal of surgical correction for hallux valgus is to achieve a painless, shoe-wearable, and relatively straight toe with a balanced joint motion that results in aesthetically and functionally satisfactory toe. To date, there has not been a consensus on the ultimate surgical procedure for hallux valgus correction. Unfortunately, such a consensus may be difficult since it is not uncommon to encounter complications after hallux valgus correction. Postoperative soft tissue complications include difficult wound healing, infection, hypertrophy, or pain of the scar, joint stiffness, and tendon or sensory nerve damage. Postoperative bony complications include malunion, nonunion, failure of fixation, failure of angle correction, recurred deformity, osteomyelitis, and failure of balance between the metatarsal heads. Herein, we review common complications after surgical correction of hallux valgus, such as stiff joint, bony complications, recurrence of the deformity, and hallux varus.
