Purpose: To compare clinical outcome of Sanders type IV intra-articular calcaneal fracture treated with open reduction and internal fixation (ORIF) versus ORIF and primary subtalar arthrodesis (PSTA). Materials and Methods: Between March 2003 and November 2013, 22 patients with 22 Sanders type 4 intra-articular calcaneal fractures were included in this study. Of these, 11 were treated with ORIF (ORIF group), and 11 were treated with ORIF and PSTA (PSTA group). The mean follow-up period was 34.6 months (range, 18-72 months). Clinical outcomes were assessed along with the American Orthopedic Foot and Ankle Society's ankle-hindfoot scale (AOFAS score), and the visual analogue scale pain score (VAS score) at 6-month, 12-month, and last follow-up. Patient satisfaction, return to previous occupation and postoperative complications were also investigated. Results: The results for ORIF did not differ from those for PSTA based on the last follow-up AOFAS scores or the VAS scores (p>0.05). However, patient satisfaction was significantly higher in the PSTA group (p=0.008). Secondary subtalar arthrodesis was conducted in five patients (45.5%) of the ORIF group within 2 years postoperatively. Conclusion: We were unable to demonstrate a significant difference in clinical outcomes between ORIF and PSTA; however, the patient satisfaction was higher in the PSTA group. PSTA may be a suitable choice for patients who need fast recovery to daily activity and to prevent the need for secondary subtalar arthrodesis.

79 surgically managed mandibular condylar fracture patients included the 25 patients treated with Dr, Nam's method were analysed the postoperative resluts in Oral and Maxillofcial Surgery, School of Dentistry, Wonkwang University since 1993 to 1995. Mean patient's age is 32.5 years (range, 8 to 65 years), and follow-up periods were a minimum of 3 months to 28 months. 19% condylar fractures were associated with mostly symphysis portion. According to the patient's age, severity of condylar fractures, clinical signs and symptoms, radiographic findings, treatmenet plans had been performed. Rigid fixation have performed greatly, and then fragment removal of fractured mesial pole of proximal segment of the condylar and little cases of reshaping and eminoplasty and lag screw have been applied. Two cases of the both condylar resorption and deviated condyle posteriorly in Dr. Nam's method. None of infection or necrosis signs of treated condyle surgically. In my opinion, whenever possible, displaced condylar fracture can be managed surgically with rigid fixation, but not Dr. Nam's method. Usually if perform the surgical management of condylar fractures you should maintain maxillomandibular fixation for 2 weeks, or more and has to follow-up functional mandibular exercise should be kept continuously.

Isolated navicular fracture and dislocation of talonavicular joint is extremely rare. It is recommended closed or open reduction for displaced fracture. We reported one case of isolated tarsal navicular fracture and dislocation of the talonavicular joint, treated with open reduction and internal fixation using K-wires.

In 1974, Casson et. al. reported midfacial degloving approach to repair the midfacial bone fracture. After then, this approach has been used frequently to treat the lesions on nasal cavity, nasopharynx, facial plastic surgery and midfacial trauma. Midfacial degloving approach consists of 1) bilateral sublabial incision 2) complete transfixion incision/ septocolumellar incision 3) bilateral intercartilaginous incision 4) bilateral pyriform aperature incision. This approach provides proper access for midfacial bone structure without facial scar but has post-operative complications such as transient epistaxis, infraorbital nerve paresthesia and nasal crust. We treated three patients using midfacial degloving approach to correct traumatic deformity in midface area. In two patients, rhinoplasty with autogenous rib graft was done simultaneously. So we report these cases with review of literatures.

Irreducible knee dislocation is a rare injury and often need an open procedure with ligaments reconstruction. This report describes a case of arthroscopic treatment of a patient with traumatic knee dislocation unable to reduce in a closed method. MRI revealed incarceration of the medial collateral ligament and capsule in the medial compartment. And arthroscopic examination confirmed incarcerated medial capsuloligamentous structures which prevented the knee from reduction. Arthroscopic procedure without ligaments reconstruction was complete when the medial condyle was well visualized and the knee reduced. After 4 weeks of immobilization in extension, range of motion exercise and gradual increases in weight bearing was allowed. At the 3- year follow-up, mild laxity was remained but the patient did not have any discomfort of doing ADL activity and showed full range of motion of the knee.

Purpose: To evaluate and report the clinical outcome after surgical treatment of intra-articular comminuted fracture of distal humerus in the elderly with osteoporosis. Materials and Methods: From January 2007 to October 2009, 24 patients aged older than 65 years with intra-articular comminuted fracture of distal humerus underwent surgical treatment. 18 patients (Group I) were managed using primary open reduction and internal fixation (OR IF) through the modified posterior approach and 6 patients (Group II) were taken primary total elbow arthroplasty. The average follow up period was 17.2 months. According to the AO classification, there were 8 C2, 16 C3 type fractures. All enrolled patients were evaluated radiographically and clinically. Clinical outcomes were assessed with the Mayo Elbow Performance, Disabilities of Arm and Shoulder and Hand, and Musculoskeletal Functional Assessment functional questionnaires. Results: The bony union was observed in 18 patients in group I at average 14 weeks. There were 2 patients with neurapraxia of whom the ulnar nerve symptom did not improve despite of anterior transposition. And non-union at osteotomy sites was seen in 2 patients. The mean Mayo Elbow Performance score was 87.0. The mean DASH score was 32.4. The average arc of elbow flexion was $121.0^{\circ}$ (range, $95{\sim}145^{\circ}$) with mean flexion-contracture of $12.0^{\circ}$ (range, 0 to 35). 6 patients in Group II showed no complication during follow up periods. The mean Mayo Elbow Performance score was 89.1. The mean DASH score was 44.3. The average arc of elbow flexion was $125.1^{\circ}$ (range, $100{\sim}145^{\circ}$) with mean flexion-contracture of $12.6^{\circ}$ (range, 0 to 30). Conclusions: With careful patient selection, Total elbow arthroplasty as well as OR IF could achieve good outcomes in elderly of comminuted intra-articular distal humerus fracture with osteoporosis.
