Hallux valgus is a deformity that causes pain in the first metatarsophalangeal joint. Surgical methods are quite diverse and a range of osteotomies are used at the proximal and distal part of the metatarsal bone and proximal phalange. Fixation methods, such as plate, screw, K-wire, and others have been used in various ways. The fixation device is often removed with various side effects due to the fixation devices. In the case of instruments that are absorbed in vivo, these procedures are not necessary to remove and there is an advantage of not performing the second operation. Three patients were treated, in which a proximal chevron osteotomy was used with a bioabsorbable screw (K-$MET^{TM}$; U&I Corporation).

Isolated fracture dislocation of the tarsal navicular bone is extremely rare. The mechanism of injury of this fracture dislocation is known as a horizontal or axial load on plantar flexed foot. Closed or open reduction is recommended for displaced navicular fracture. We report one case of isolated fracture dislocation of the tarsal navicular which was treated with closed reduction and percutaneous K-wire fixation.

Secondary soft tissue injuries can occur from the pressure of the displaced fragment of posterior calcaneal tuberosity in calcaneal tongue-type fractures and calcaneal tuberosity avulsion fractures. The soft tissue injury can be prevented by immediate reduction of the displaced fragments. Various techniques can be used to fix the fracture fragments, but the stability of fixation and minimal invasiveness to soft tissue should be considered. This paper reports the successful outcomes of patients with soft tissue compromises in calcaneal tongue-type fractures and calcaneal tuberosity avulsion fractures. The fixation technique of a large cannulated screw and simple cerclage wiring is believed to be a useful surgical option for the treatment of secondary soft tissue compromised calcaneal fractures.

The purpose of this study is to analyze the early results by the operative methods in 36 patients with pectus excavatum during the period August 1989 to August 1993. We underwent Ravitch`s operation in 15 patients [mean age : 11.0], which consists of subperichondral resection of all deformed cartilages, anterior wedge osteotomy and fixation in place with wire sutures of the sternum, and sternal eversion operation in 21 patients[mean age : 5.3], which consists of en-bloc resection of deformed sternum and cartilages, tailoring of the costal cartilages and shaping of the sternum and fixation of sternum and cartilages. Early results were satisfactory in 93% [Excellent 93%] for Ravitch`s operations and in 100% [Excellent 90% and Good 10%] for sternal eversion operations. But late results by sternal growth will be necessary longer follow-up.

Periprosthetic fracture after total elbow replacement surgery is a difficult complication to manage, especially when it comes together with implant loosening. If stem revision and internal fixation of the periprosthetic fracture are performed simultaneously, this would be a very challenging procedure. Most of total elbow replacement implants are cemented type. Cement usage at periprosthetic fracture site may interfere healing of fractured site. Authors underwent internal fixation with use of locking plate and cerclage wire for periprosthetic fracture, allogenous fibular strut bone inserted into the humerus intramedullary canal allowing the fractured site to be more stable without cement usage. At 10-month follow-up, the complete union and good clinical outcome was achieved. We present a novel technique for treating periprosthetic fracture with implant loosening after total elbow replacement surgery, using intramedullary allogenous fibula strut bone graft.

Meniscectomy is indicated for the internal derangement of disk with perforation and gross morphological changes, nonreactive to conservative treatment procedures. After the meniscectomy, permanent disk replacement can be followed. Variable materials have been introduced for disk replacement. Of them, relatively harder replacing materials should have been fixed with surgical wire only. This poor fixation method provide inadequate retentive force and conclusively can be attributed to postoperative noise, poor prognosis. We tried to use biocompatible fibrin adhesive in order to obtain additional fixation force in the method above mentioned and treated two patients with the late stage of internal derangement of disk In both cases, satisfactory results were obtained.

Purpose: The authors evaluated the differences between K-wires and Cannulated screw, plate for fixing the proximal metatarsal chevron osteotomy of moderate and severe hallux valgus. Materials and Methods: There were 62 patients (79 feetz) who were moderate and severe degree hallux valgus according to the classification of Mann. They all got the proximal chevron osteotomy when correcting the deformity. We divided the patients into 4 groups, Two K-wire fixed group as A, one cannulated screw fixed group as B. Two cannulated screw fixed group as C, Plate fixed group as D, Group A were patients (26 feet) and Group B were patients z(9 feet), Group C were patients (31 feet) and Group D were patients (13 feet). Preoperative, postoperative and follow-up hallux valgus angle (HVA) and intermetatarsal angle (IMA) were measured for each patient. ANOVA test and Student t-test were done for statistical analysis. Results: Mean follow up period was 43.8 months (range: 12~82 months). Preoperative mean IMA was $16.4{\pm}3.5$, $17.7{\pm}11.3$, $17.3{\pm}5.9$ and $16.6{\pm}2.3$ degrees in respectively group A, B, C, D. Immediate postoperative mean IMA was $5.6{\pm}3.4$, $7.3{\pm}4.4$, $7.6{\pm}4.4$ and $6.7{\pm}2.8$ degrees in respectively group A, B, C, D. The final mean IMA was $8.9{\pm}4.5$, $15.2{\pm}7.5$, $10.3{\pm}4.4$ and D $7.7{\pm}3.5$ degrees in respectively group A, B, C, D. There were significant statistical increase in final mean IMA of group B and C (p<0.05). Conclusion: The IMA was significantly increased in the group which used one or two cannulated screw for fixation on follow up, therefore more caution should be needed when using one or two cannulated screw fixation technique after proximal chevron osteotomy.

In an open reduction of the mandibular angle fracture, it is crucial to approximate each fracture segment as closer as possible for the reduction of the healing period. In this case report, we proposed a new technique for the mandibular angle fracture. This was designed to minimize the gap between two separated segments using mini-implants and surgical wires. Mini-implants were placed around the fracture line, followed by wire ligation to minimize the fracture gap. And then internal fixation was easily employed with plates and screws. The advantages of this technique were reduced time for operation, the promotion of healing, rapid functional recovery, and few complications.

Background: The zygoma is the most prominent portion of the face. Almost all simple zygomatic arch fractures are treated in a closed fashion with a Dingman elevator. However, the open approach should be considered for unstable zygomatic arch fractures. The coronal approach for a zygomatic arch fracture has complications. In this study, we introduce our method to reduce a special type of unstable zygomatic fracture. Methods: We retrospectively reviewed zygomatic arch view and facial bone computed tomography scans of 424 patients who visited the Wonju Severance Christian Hospital from 2007 to 2010 with zygomaticomaxillary fractures, among whom 15 patients met the inclusion criteria. Results: We used a Dingman elevator and K-wire simultaneously to manage this type of zygomatic arch fracture. Simple medial rotation force usually collapses the posterior fractured segment, and the fracture becomes unstable. Thus, the posterior fracture segment must be concurrently elevated with a Dingman elevator through Keen's approach with rotation force applied through the K-wire. All fractures were reduced without any instability using this method. Conclusion: We were able to reduce unstable and difficult zygomatic arch fractures without an open incision or any external fixation device.

Purpose: The purpose of this study was to document the results of fixation with ethibond suture in akin osteotomy and its advantages. Materials and Methods: From May 2001 to January 2004, Akin osteotomy was performed in 218 patients. We reviewed 110 patients (114 feet) who were possible radiographic evaluation more than 6 months after operation. 110 feet had hallux valgus and 4 feet had hallux valgus interphalangeus. 105 patients were female and 5 were male. The average age was 43.8 years old (18 to 68 years old). The average follow up was 9 months (6 to 23 months). After performing the Akin osteotomy at 7 mm from the proximal articular surface of the proximal phalanx, one hole is made on either side of the osteotomy site with a K-wire. The passer was passed through the both holes and the ethibond was passed. And then, the ethibond was tied tightly. 2 sutures in 66 feet and 1 suture in 48 feet were made. Radiographic bone union at 6 months follow up was regarded as success and loss of the reduction, nonunion was regarded as failed. Results: In the radiographic evaluation, bony union were made at 6 months follow up in all feet. There was no difference between 2 sutures and 1 suture, and the knots were removed in 3 feet because of skin irritation. Conclusion: The fixation of the osteotomy site using suture material was an effective method in Akin osteotomy. The advantage of this procedure was unnecessity of the material removal.
