  • Introduction: The placement of a single miniplate is not sufficient to achieve rigid fixation in mandibular angle fractures. It often causes difficulties in reducing the intermaxillary fixation (IMF) period. Consequently, the placement of 2 miniplates is preferable. The intraoral approach in an open reduction and internal fixation (ORIF) of a mandibular angle fracture with 2 miniplates is often challenging. Accordingly, an alternative of transbuccal approach is performed. However, this method leaves a scar on the face and can result in facial nerve injury. This clinical study suggests a protocol that can maintain rigid fixation without a transbuccal approach in mandibular angle fractures. Materials and Methods: The subjects were 7 patients who sustained fractures of the mandibular angle and treated at Department of Oral and maxillofacial surgery, Sacred Heart Hospital, Hallym University. ORIF under general anesthesia was done using the intraoral approach. One miniplate was inserted on external oblique ridge of the mandible, and the other was placed on lateral surface of the mandibular body with contra-angle drill and driver. A radiographic assessment and occlusal contact point examination was carried out before surgery, and 2, 4 and 6 weeks after surgery. Results: The mean operation time was 80 minutes. Regarding the occlusion state, the number of contact points increased after surgery. Paresthesia and infection were reported to be complications before surgery. Conclusion: The placement of 2 miniplates using contra-angle drill for ORIF of mandibular angle fractures allows early movement of the mandible without IMF. We propose this approach to reduce the patients’discomfort and simplify the surgical procedure.

  • Purpose: It is very important to evaluate and fix coronoid process fractures because they are a critical element for a stable, effective elbow function. The lateral view of the elbow joint is used for a radiographic evaluation of the coronoid but an understanding of the fracture pattern is often difficult because of overlap of the radial head and obliquity of the fracture line. We developed the coronoid view, which is a new radiograph for an evaluation of the coronoid process fracture, and discuss its advantages for a postoperative follow-up. Materials and Methods: The coronoid view was designed for an evaluation of the anteromedial fragment of the coronoid process. After the patient sat on his side, the shoulder was abducted $45^{\circ}$ and the elbow was flexed $90^{\circ}$. The X-ray beam was shot perpendicular to the table. Since shoulder was abducted $45^{\circ}$ the fracture line of the coronoid process can be parallel to the X-ray beam, and the radial head can be cleared. Conclusion: The coronoid view can be a good alternative radiograph for an evaluation of a coronoid process fracture because the beam is parallel to the fracture line. The coronoid view can be particularly useful in postoperative patient follow-up where computed tomography is impractical due to metal implants and cost.

  • Purpose: To evaluate the usefulness of minimally invasive arthroscopy-assisted plate removal of a laterally inserted periarticular distal femur plate used for the treatment of AO type-C distal femur fractures. Materials and Methods: From October 2002 to November 2005, we evaluated 17 patients whose plates were removed through minimally invasive arthroscopy-assisted plate-removal technique and 15 patients who got their plates removed through conventional method without using arthroscopy, 32 patients in total. All these patients included in this study initially underwent open reduction and internal fixation of the distal femoral fractures with a lateral plate, and complained of continued pain over the lateral femoral condyle after the fracture fixation. The average age was 42.6 (ranges: 20~66) and initial fracture types included 16 cases of C1, 11 cases of C2, and 5 cases of C3 following AO/ASIF classification guidelines. Measured outcomes included: associated intra-articular pathologies, time needed to return to activities of daily living, patients' overall satisfaction, complications following the removal of hardware, and pain before and 6 months after the operation. Results: The distal-most end of the plate was placed in the knee joint in all cases and damage of the lateral articular capsule was found in 23 cases. Continuous wound discharge after surgery was found in one case who underwent arthroscopy-assisted plate removal, and it was treated by irrigation and re-suture. Average time needed to return to activities of daily living was 7 days in arthroscopy assisted group and 7.6 days in conventionally removed group. Fourteen patients (82.4%) who underwent arthroscopyassisted plate-removal reported above 'fair' satisfaction and the Visual analog scale pain score decreased from 4.9 to 1.9, six months after the plate removal. Thirteen patients(86.7%) who underwent conventional plate removal reported above 'fair' satisfaction and the Visual analog scale pain score decreased from 5.2 to 2.5, six months after the operation. Conclusion: Through minimally invasive arthroscopic-assisted plate removal, intrarticular pathology of the knee joint was able to be simultaneously identified and treated at the time of hardware removal. Damage of lateral capsule of the knee joint caused by the inserted plate for the treatment of type C distal femoral fracture was very frequently found and following the plate removal, patients experienced an improvement in pain score. We therefore recommend routine lateral distal femoral plate removal if the bony union is attained in such cases as type C distal femoral fractures whose distal most end of the plates are located in the joint.

  • Purpose: To evaluate and compare the results of children with displaced supracondylar fractures of humerus treated with open reduction and pinning with closed reduction and pinning. Materials and Methods: From March 2002, we treated 17 patients with completely displaced supracondylar fractures under the age of 7 with a minimal follow up period of 6 months. 9 patients were treated with closed reduction and pinning and 8 patients were treated with open reduction and pinning. The clinical results were evaluated with Flynn's criteria. Time to bone union was also analyzed for these two set of patients. Results: The group treated with open reduction had 6 excellent and 2 good results for change in carrying angles, 5 excellent, 2 good and 1 fair results for motion loss evaluated by Flynn's criteria. The average time to bony union for this group was 5.8 weeks. The group treated with closed reduction had 6 excellent, 2 good, and 1 fair results for change in carrying angles and 7 excellent, 1 good and 1 fair results for motion loss. The average time to bony uinon for this group was 3.7 weeks. Conclusion: In treating completely displaced supracondylar fractures of humerus in children, the closed reduction method and open reduction method all showed good results. But the operation time, duration of hospital stay and time to union was somewhat shorter for the patients treated with closed redution and pinning.

  • Purpose: Primary bone tumors of hindfoot are uncommon compared with other locations, and there have been few large-group studies. This study was designed to analyze the characteristics and the clinical results of the primary bone tumors of hindfoot. Materials and Methods: Forty five cases in 44 patients who have been diagnosed from 1989 to 2011 were reviewed. The minimum follow-up period was 1 year. We retrospectively reviewed the medical records and images. Results: Twenty six cases were male and 18 cases were female. Mean follow-up period was 33.1 months and mean age was 25.1 years. Forty four cases were benign and 1 case was malignant. Thirty six cases occurred in calcaneus and 9 cases were in talus. The most common benign bone tumor was simple bone cyst (20 cases), followed by intraosseous lipoma (12 cases), and chondroblastoma (4 cases). In calcaneus, there were 18 cases of simple bone cyst, and 12 cases of intrasosseous lipoma. In talus, there were 3 cases of chondroblastoma, 2 cases of simple bone cyst, and 2 cases of intraossesous ganglion. Many patients with hindfoot bone tumors presented with pain, but some were found accidentally. Patients received surgical procedures, such as curettage and bone graft, open reduction and internal fixation, tumor resection, and below knee amputation. Conclusion: Primary bone tumors of hindfoot are rare and can be misdiagnosed as ankle sprain or contusion. Although most are benign, malignant tumors cannot be ruled out, so early diagnosis and appropriate treatment is important.

  • Purpose: Bipolar hemiarthroplasty is used as an alternative to open reduction and internal fixation for unstable intertrochanteric fractures in elderly patients. Recent advances in medical systems and technologies have resulted in increased survival rates after intertrochanteric fractures of the femur, requiring selection of the appropriate femoral stems considering the mid- to long-term duration of survival. Hemiarthroplasty was performed for unstable intertrochanteric fractures using a double tapered quadrilateral femoral stem (C2 stem), and the clinical and radiological results were evaluated as a five-year follow-up post-surgery. Materials and Methods: From January 2004 to December 2013, 43 patients (43 hips) who underwent hemiarthroplasty with a C2 stem were enrolled in this study. Their mean age was 78.6 years (range, 70-84 years), and the mean follow-up period was 85.4 months (range, 60-96 months). During the follow-up period, clinical parameters, such as the changes in pain, walking ability, and functional status, were examined. Radiologically, changes in the proximal femur, such as osteoporosis and bone resorption of cortical bone, were noted. Complications that occurred during the follow-up period, such as dislocation and prosthetic features, were also reviewed. Results: Initially, the pain was relieved postoperatively, but it increased four years after surgery. The walking ability was reduced by two steps in nine patients after 60 months, and the Harris hip score was reduced significantly postoperatively after two to three years. Radiologically, cortical osteoporosis occurred in 14 patients. Five patients developed cortical bone resorption. Four of them showed nonunion of the trochanteric fracture fragments, and three of them suffered reverse oblique fractures. Conclusion: Careful selection considering the general health condition and remaining lifespan of the patient would be necessary for primary hip hemiarthroplasty using a 3C type cementless femoral stem for unstable intertrochanteric fractures in elderly patients with osteoporosis.

  • Purpose: The aim of this study is to evaluate the clinical result of intra-articular fractures of the distal humerus (AO type C) in elderly osteoporotic patients treated with double tension band osteosynthesis. Materials and Methods: From January 2006 to December 2010, 10 elderly osteoporotic patients(1 male, 9 females) with intra-articular fractures of the distal humerus (AO type C) were treated with double tension band osteosynthesis. The mean age of patients at the time of surgery was 74.6(66~84) years and the mean follow-up period was 39.2(20~74) months. The fracture union and complications were assessed and the functional result was evaluated by the rating system of Jupiter et al. and the Mayo elbow performance index. Results: Bone union was achieved in all patients with no secondary displacement. The mean time for union was 16.6(13~22) weeks. The average postoperative arc of elbow flexion was 119(100~140) degrees with a mean flexion contracture of 8.5(0~15) degrees. The recovery in two patients was rated as excellent, in 7 as good, and in 1 as fair in terms of the Mayo elbow performance index with average value of 82(70~90) points. Seven patients were rated as excellent, 1 as good, and 2 as fair in terms of the rating system of Jupiter et al. Changing tension band wiring was performed in one patient as skin irritation was noticed due to tension band knots. Heterotopic ossification developed in one patient but had no symptom. Conclusion: Double tension band osteosynthesis in intra-articular fractures of distal humerus (AO type C) in elderly osteoporotic patients can provide sufficient and secure stability to allow early rehabilitation.
