Fractures located at the metaphyseal/diaphyseal junction at the base of the fifth metatarsal were first described by Sir Robert Jones in 1902. However, ever since, there has been disagreement and debate regarding the diagnosis, classification, pathomechanics, the incidences, and potential causes of delayed unions and nonunions, and the optimal method of treatment. It appears to be widely agreed that proximal fractures of the metaphyseal/diaphyseal region of the fifth metatarsal are prone to delayed union or even nonunion. Several classifications of proximal fifth metatarsal stress fractures have been devised. Torg et al. classified fractures involving the proximal part of the diaphysis of the fifth metatarsal into three types. The Torg classification is a good grading system that can be used to determine the type of surgery needed as well as for the prediction of prognosis. The ''plantar gap'' might add to the decision-making process for surgery and improve the prediction of patient prognosis. In addition, the new classification using 'plantar gap' might be used for classification of fifth metatarsal stress fracture. Fifth metatarsal stress fractures can be treated conservatively or surgically, and excellent results have been reported for surgery with rapid recovery in athletes. Intramedullary screw fixation has become a popular form of fixation for fifth metatarsal stress fractures. Bone grafting presents the problems of a longer recovery time and additional skin incision for harvesting. The modified tension band wiring is an useful and simple option for surgical treatment of challenging fifth metatarsal stress fractures.
Purpose: The authors intended to analyze the operative results of tarsal tunnel syndrome. Materials and Methods: Twenty-one patients with tarsal tunnel syndrome were followed for more than 1 year after operation. The mean age was 44 years, and the mean follow up period was 2 years and 9 months. Clinically preoperative and postoperative AOFAS ankle-hindfoot score and visual analogue scale for pain were analyzed. Radiologically the cause of disease was investigated, and the size of mass was measured, if possible. The duration of symptom, the presence of space occupying lesion (SOL), the effect of epineurolysis were statistically analyzed to see the relation with the operative results. Results: Operative release of tarsal tunnel was done in all cases, and epineurolysis was done in 11 cases. The causes of the disease were 10 soft tissue masses, 7 talocalcaneal coalitions, 1 nonunion of medial talar process fracture, and 1 pes planovalgus, and 3 idiopathic cases. The masses were subdivided into 7 ganglions, 2 neurilemmomas, and 1 lipoma. There was 1 case of combined talocalcaneal coalition and ganglion. Clinically AOFAS ankle-hindfoot score was increased from 62.7 points preoperatively to 84.3 points postoperatively. Visual analogue scale was improved from 6.5 preoperatively to 2.2 postoperatively. Two cases were graded as unsatisfactory. One was severe pes planovalgus, and the other was idiopathic case. The duration of symptom and the epineurolysis were not related with the results. However the presence of space occupying lesion was significantly related with the good results. Conclusion: Early operative release of tarsal tunnel appears to be important for the improvement of symptom. However the prognosis is limited in case that there is no SOL.
Purpose: The authors intended to analyze the operative results of moderate hallux valgus with proximal chevron metatarsal osteotomy and distal soft tissue procedure. Materials and Methods: Seventy feet of fifty-seven patients were followed for more than 1 year after the proximal chevron metatarsal osteotomy. The mean age was 47.2 years, and the mean follow up period was 2 years and 3 months. Clinically preoperative and postoperative AOFAS MP-IP scale and satisfaction after the surgery were analyzed. Radiologically hallux valgus angle, hallux valgus interphalangeal angle, the intermetatarsal angle and sesamoid position before and after the operation were analyzed. Results: Additional Akin osteotomy was performed 48 out of 70 feet. Clinically AOFAS MP-IP scale was increased from 60.4 points preoperatively to 89.8 points postoperatively. Ninety-four percents of the patients were satisfied with the results. Radiologically hallux valgus angle was decreased from $34.8^{\circ}$ preoperatively to $12.8^{\circ}$ postoperatively. The intermetatarsal angle was decreased from $15.7^{\circ}$ preoperatively to $8.0^{\circ}$ postoperatively. Hallux valgus interphalangeal angle was increased from $7.4^{\circ}$ preoperatively to $9.8^{\circ}$ postoperatively. There were 3 recurrences, 1 hallux varus and 3 minor wound infections. There were no nonunion or malunion of the 1st metatarsal. Conclusion: Proximal chevron metatarsal osteotomy with distal soft tissue procedure and additional Akin osteotomy appears to be safe and satisfactory procedure.

Objectives: The aim of this study was to evaluate the implication of third molars in postoperative complications of mandibular angle fracture with open reduction and internal fixation (ORIF). Materials and Methods: Data were collected on patients who presented with mandibular angle fracture at our Department of Oral and Maxillofacial Surgery between January 2011 and December 2015. Of the 63 total patients who underwent ORIF and perioperative intermaxillary fixation (IMF) with an arch bar, 49 patients were identified as having third molars in the fracture line and were followed up with until plate removal. The complications of postoperative infection, postoperative nerve injury, bone healing, and changes in occlusion and temporomandibular joint were evaluated and analyzed using statistical methods. Results: In total, 49 patients had third molars in the fracture line and underwent ORIF surgery and perioperative IMF with an arch bar. The third molar in the fracture line was retained during ORIF in 39 patients. Several patients complained of nerve injury, temporomandibular disorder (TMD), change of occlusion, and postoperative infection around the retained third molar. The third molars were removed during ORIF surgery in 10 patients. Some of these patients complained of nerve injury, but no other complications, such as TMD, change in occlusion, or postoperative infection, were observed. There was no delayed union or nonunion in either of the groups. No statistically significant difference was found between the non-extraction group and the retained teeth group regarding complications after ORIF. Conclusion: If the third molar is partially impacted or completely nonfunctional, likely to be involved in pathologic conditions later in life, or possible to remove with the plate simultaneously, extraction of the third molar in the fracture line should be considered during ORIF surgery of the mandible angle fracture.
The fractures of lateral end of clavicle can be treated by conservative or operative treatment, but many authors report the higher rate of non-union with conservative treatment and that the operative treatment is more effective for the type II fractures. The authors reviewed and analysed 15 cases of lateral end fracture of clavicle which had been treated at Department of Orthopedic Surgery, Kyungpook National University Hospital from 1991 to 1996. The results were as follows; 1. Among the 15 patients, male was 6,female 9 and the average age was 46.2 years ranged from 21 to 72 years. 2. According to the classification by Rockwood, type II a was 8 cases and II b was 7 cases. 3. We treated operatively 12 cases, 9 cases with tension band wiring and 3 cases with intramedul-Iary K-wire fixation. And we treated conservatively 3 cases with Velpeau cast, but I case of nonunion was treated with tension band wiring. 4. The average follow-up was 3.2 years ranged from 2.1 to 4.7 years. 5. The functional results were evaluated with Weitzman's classification. 6. In the operatively treated cases, there were 4 cases(30.7%) in excellent, 7 cases(53.8%) in good and 2 cases(15.3%) in fair result. But, in the conservatively treated cases, there were 2 cases in good and I case in poor result, and the poor case did not united and had open reduction and internal fixation. 7. In conclusion, the operative treatment revealed good functional results in most cases (10/12) and early open reduction and internal fixation was better method than conservative treatment.
Introduction : The goal in the management of soft tissue injuries of the lower extremity is to obtain a closed stable wound as soon as possible. Recently, An anatomic study that has shown the role of the vascular axis that follows the superficial sensory nerves in supplying the skin developed the concept of a neuroskin island flap. It has been suggested that skin island flaps supplied by the vascular network of the saphenous nerve is one of the most reliable treatment to skin defect below the knee joint. Purpose : The aim of this article is to present a clinical experience of neuroskin island flaps based on the saphenous nerve and to estimate the clinical utilities of distally based saphenous neuroskin flap. Materials and Methods : From September 1995 to May 2000, a total 12 distally based neuroskin island flaps supplied by the vascular axis of the saphenous nerve were performed to cover defects in pretibial area below the knee. Result : flap necrosis due to reactivation of existing infection developed in a case that skin defect had been on infected nonunion site of tibia. But other 11 cases survived completely without any specific complications. Conclusion : The distally based neuroskin pedicled island flap using the vascular network of the saphenous nerve are versatile and reliable and especially indicated for limited defects in pretibial area below the knee joint which are not good indications for other better-known flaps.
Background: For Neer type IIB fracture of distal clavicle with coracoclavicular ligament injury, various surgical treatments have been used in literatures. However, there was no consensus on the optimal treatment. The aim of this study is to report the clinical and radiological results of open reduction and internal fixation of unstable distal clavicle fracture and suture augmentation of disrupted coracoclavicular ligament. Methods: A prospective study was performed in 23 patients with Neer type IIB distal clavicle fracture in Seoul Medical Center, Eulji Hospital, and National Medical Center. Firstly, suture anchors are inserted in the base of coracoid process and preliminary reduction was achieved by tie-off of three suture limbs around the clavicle. Then, the final fixation was completed with anatomical locking plate. Bony union and the distance between coracoclavicular ligaments were evaluated. Clinical results and complications including stiffness and secondary procedures were evaluated. Results: Bony union was achieved in all cases except one (22 of 23). At mean 14.9 months, no significant difference in the mean coracoclavicular distance was observed compared to uninjured shoulder ($8.2{\pm}7.9mm$ versus $7.3{\pm}3.4mm$, p=0.14). Pain visual analogue scale, American Shoulder and Elbow Surgeons score, Constant score, and Disabilities of the Arm, Shoulder and Hand score were 0.5, 83.4, 78.5, and 6.2, respectively. Revision surgery was performed in one case of nonunion. Four patients who complained of skin irritation underwent implant removal. Conclusions: In cases of an unstable distal clavicle fracture with coracoclavicular ligament disruption, satisfactory clinical results were obtained by locking plate fixation and coracoclavicular ligament suture augmentation concurrently.

The traditional methodology in Ewing's sarcoma was chemotherapy and radiotherapy. Recently surgery is reemerging as an important therapeutic tool and some paper report increased survival with it. The purpose of this nonrandomized study is to evaluate our result of Ewing's sarcoma with surgery, retrospectively. We experienced 30 cases for seven years and among them 6 were extraskeletal. In location, axial was 10 cases and peripheral was 20. By Enneking's classification, state IIB was 26 cases and IIIB was 4. Eighteen patients took operation, chemotherapy and/or radiotherapy, and remaining twelve took chemotherapy and/or radiotherapy only. Type of operation was limb salvage in 16 cases and amputation 2. Average dosage of radiation was 45.1Gy. Six kinds of chemotherapeutic regimen were used, but among them main protocols were Ifosfamide-Adriamycin(17 cases) and IESS(Cytoxan, Adriamycin, Methotrexate, Vincristine:8 cases). Complications were as follows. In operation group, there were 3 local recurrence and one case of nonunion. In nonoperated group, one local recurrence and one pancytopenia resulting in death. Average follow up was 29.7 months. Kaplan-Meier's ten year actuarial survival rate for the whole 30 cases was 26.8%. Significant difference in survival exists between central and peripheral lesions(p=0.05, by log rank test). Types of chemotherapy and surgery itself showed no significance. But surgery is important in function and local control. More intensive chemotherapeutic regimen to prevent distant metastasis and combined surgery and radiotherapy may be needed in Ewing's sarcoma.
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.
Purpose: The aim of this study was to retrospectively evaluate the clinical and radiological results of the first metatarsophalangeal joint arthrodesis with two crossed screws fixation. Materials and Methods: We treated 23 patients (24 cases) with arthrodesis of the first metatarsophalangeal joint using two crossed screws fixation between December 2000 and May 2005. There were 3 male patients and 20 female patients. Ages ranged from 28 to 74 years (mean, 50 years). Follow-up ranged from 4.1 to 8.2 years (mean, 6.5 years). The American Orthopaedic Foot and Ankle Society (AOFAS) score and their satisfaction was evaluated clinically, foot anteroposterior and lateral radiograph, radiologically. Results: Of the 24 cases, 6 had surgery for dorsal plate and screws fixation because of failure to acquire firm fixation with two crossed screws fixation. All 6 cases acquired bony union. Fusion of the hallux first metatarsophalangeal joint occurred in 16/18 cases (89%). Nonunion occurred in 2 cases (11%) and was asymptomatic. At last follow-up, hallux valgus angle ranged from 11 to 25 degrees(mean, 17.7 degrees), dorsiflexion ranged from 15 to 25 degrees (mean, 22 degrees).The mean preoperative AOFAS score of 37 points(range, 28 to 45 points) improved to a mean of 77 points (range, 65~90 points) postoperatively. The result of the procedure as rated subjectively by the patient was excellent for 5 cases, good for 11 cases and fair for 2. Conclusion: Comparatively, the arthrodesis of the first metatarsophalangeal joint with crossed screws fixation showed a satisfactory clinical results, we thought that require technical attention for firm fixation in operation.
