Os acromiale is the rare shoulder disease and its treatment is controversial. Despite conservative treatments for 6 months include medication, exercise, physical therapy and subacromial steroid injections, operative treatment for uncontrolled symptomatic Os acromiale is considered the treatment of choice. Operative treatment includes excision, arthroscopic or open reduction and internal fixation with a bone graft. Open reduction with tension band wiring and a bone graft is now the preferred treatment. We experienced 8 patients with symptomatic Os acromiale from March, 2001 to March, 2006. The average patient's age was 45 years and the man and women ratio were 2: 6. All 8 cases of symptomatic Os acromiale of the mesoacromion were treated with open reduction and internal fixation using tension-band wiring. The preoperative ASES($47.3\pm24.4$) and UCLA ($16.6\pm5.8$)scores were improved to $88.8\pm7.3$ and $31.5\pm1.9$, respectively, at the 2 year follow up. The overall UCLA score showed 1 excellent result and 7 good results. We think that symptomatic Os acromiale is a specific disease entity, and open reduction and internal fixation using tension-band wiring with K-wire is a good treatment modality.

Midshaft clavicle fractures are the most common fracture of the clavicle accounting for 80% of all clavicle fractures. Traditionally, midshaft clavicle fractures are treated with conservative treatment even when prominent displacement is observed; however, recent studies revealed that nonunion or malunion rate may be higher with conservative treatment. Moreover, recent studies have shown better functional results and patient satisfaction with surgical treatment. This review article provides a review of clavicle anatomy, describes the current clavicle fracture classification system, and outlines various treatment options including current surgical options for clavicle fracture in adults.

The purpose of this case report was to introduce the concept of orthodontic and orthopedic treatment for a growing patient with Tessier number 0 cleft. A 5-year-old boy patient with Tessier number 0 cleft presented congenitally missing maxillary central incisors (MXCI), a bony defect at the premaxilla, a constricted maxillary arch, an anterior openbite, and maxillary hypoplasia. His treatment was divided into three stages: management of the bony defect at the premaxilla and the congenitally missing MXCIs using a fan-type expansion plate, iliac bone grafting, and eruption guidance of the maxillary lateral incisors into the graft area for substitution of MXCIs; management of the maxillary hypoplasia using sequential facemask therapy with conventional and skeletal anchorage; and management of the remaining occlusal problems using fixed orthodontic treatment. The total treatment duration was 15 years and 10 months. Class I canine and Class II molar relationships and normal overbite and overjet were achieved at the end of treatment. Although the long-term use of facemask therapy resulted in significant protraction of the retrusive maxilla, the patient exhibited Class III profile because of continued mandibular growth. However, the treatment result was well maintained after 2 years of retention. The findings from this case suggest that interdisciplinary and customized approaches are mandatory for successful management of maxillary hypoplasia, bony defect, and dental problems in Tessier number 0 cleft. Moreover, considering the potential of orthognathic surgery or distraction osteogenesis, meticulous monitoring of mandibular growth until growth completion is important.

Purpose: We report a case that iatrogenic dorsiflexion deformity after hallux valgus surgery treated successfully with crescenteric plantar flexion metatarsal osteotomy. Materials and Methods: 43 years old female who suffered from left fore foot pain and deformity after hallux valgus surgery was evaluated. Results: Preoperatively she did not put on ordinary shoes and had had persistent pain and discomfort on 1st metatarsal area. She also had a callus on plantar surface of 2nd metatarsal head. Simple AP and Lateral x-ray identified that 1st metatarsal bone had a 23 degree dorsiflexion deformity. For correction of deformity, plantarflexion crescenteric osteotomy was performed on proximal 1st metatarsal area. After operation, All of symptom eliciting patient was gone and 43 points of AOFAS scale preoperatively improve 100 points and the patient very satisfied. Post operative x-ray was showing complete correction of deformity. Conclusion: As a treatment of iatrogenic dorsiflexion deformity after hallux valgus surgery, the crescenteric plantar flexion osteotomy can be good and safe modality for correction.

The treatment of tibial shaft fracture has become one of the most controversial subjects in orthopedic surgery. Comminuted, segmental and rotationally unstable fractures or bone defect at fracture site have problems of the fixation. The interlocking nail solve these problems. We have experienced 8 cases of the tibial shaft fractures treated with interlocking nail from 1986 to 1988. Authors analysed these cases and our own clinical study. The results were as follows. 1. The average bone union rate was about 15 weeks. 2. The interval between operation and crutch walking was 4:3 weeks. 3. The merits of this operation were the short hospitalization and early adaptation of social activity. 4. The advantage is be able to do early ambulation without following muscular atrophy or joint stiffness. 5. The results were assessed on clinical examination and radiographic appearance by Hamza et al. An excellent results were 7 cases and good result was 1 case.

Purpose: We tried to evaluate the usefulness of the arthroscopy in the operative treatment of intra-articular calcaneal fracture. Materials and Methods: Between March 2005 and May 2008, 9 patients with intra-articular calcaneal fractures（Tongue type or Sanders type IIC) were treated with arthroscopically assisted percutaneous reduction and screw fixation. American orthopedic foot and ankle society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS), preoperative and postoperative Bohler's angle and the rate of complication were evaluated. Results: AOFAS score at postoperative 1 year was 88.2 (range, 71-92), and mean VAS score was 2.8 (range, 1-4). Bohler angle was improved from preoperative mean $16.2^{\circ}$ to postoperative mean $29.7^{\circ}$. There were no complications such as wound problem, infection or nerve injury. Conclusion: Subtalar arthroscopy provides precise view of posterior facet during the operation. Therefore, it can be a useful tool in treating intra-articular calcaneus fractures, especially tongue type and Sanders type IIC fractures.

Purpose: The diabetic foot lesions are intractable, and aggravation often leads to amputation. None or minor amputation group was treated debridement or toe amputation and major amputation group was treated Ray, Lisfranc, Chopart, Below Knee and Above Knee amputation. We investigate the risk factors for major limb amputations among patients with diabetic foot lesion. Materials and Methods: The subjects were 73 diabetic foot lesion patients (83 diabetic foot lesions) treated at our department from January 2006 to December 2010. Non or Minor amputation group of 44 cases were treated with debridement or toe amputation. Major amputation group of 39 cases were treated with Ray, Lisfranc, Chopart, below or above Knee amputation. We investigated socioeconomic factors, diabetes mellitus related factors and wound related factors and laboratory factors. Statistical analysis was done by Students t-test, Chi-square test, Mann-Whitney's U test. Results: In our analysis, wound size, wound classification (Wagner classification, Brodsky classification), white blood cell counts, polymorphoneuclear neutrophil percentage, hemoglobin, C-reactive protein and albumin were risk factors for major amputation (p<0.05). Conclusion: Low education level, nutritional condition, premorbid activity level and progressed wound condition were observed in major amputation group compared with non or minor amputation group. In the major amputation group, higher white blood cell count, C-reactive protein level and lower albumin level were observed. Together with maintenance of adequate nutritional condition, early detection of lesions and foot care for early treatment is important. Therefore, active investigation with full risk evaluation of vascular complication is also important.

Between 1992 and 1996, 5 patients with the giant-cell tumor of the spine were treated. Four were female and one was male. The mean age was 34 years old, and the mean follow-up time was 36 months. The locations of the lesions were the cervical spine in 1, the thoracic spine in 3, and the lumbar spine in 1. Pain was the predominant presenting symptom in all cases and four had a neurological deficit. A combined anterior and posterior surgical approach wds as performed in all cases, which were also treated with AIF(anterior interbody fusion) and anterior and/or posterior instrumentation. Adjuvant radiation therapy was performed in 1 case of cervical spine. At the final follow-up, the pain and neurologic symptoms were improved. Radiologic examination showed no evidence of local recurrence and no failure of instrumentation of the spine.

Melorheostosis is a rare disease, belonging to the sclerotic bone dysplasia group. Initially described by Leri and Joanny in 1922, its etiology remains unknown. Onset is usually insidious, with deformity of the extremity, pain, limb stiffness, and limitation of motion in the joints. The typical radiographic appearance consists of irregular hyperostotic changes of the cortex, resembling melted wax dripping down one side of a candle. Treatment is usually symptomatic and conservative; however, conservative treatment is unsatisfactory due to functional issues when involving the distal extremity. We report on two cases of melorheostosis with synovial chondromatosis of the foot treated by mass excision.
