Purpose: The purpose of this study was to figure out the appropriate and systemic insurance charge for the hallux valgus operations. Materials and Methods: 5 Hospitals for hallux valgus operations were analyzed how they have been charging the national health insurance corporation for their operation fees and how to use the estimated guide and authoritive interpretation through the guide book of health insurance medical treatment grant expense and the guide book of Health insurance medical treatment. Results: There are nothing for guiding principle of hallux valgus operations in both books but a guide of Mcbride operation which is approved 'JA-93-KA and JA-31' for operation fee. So majority of hospitals have charged operation fee depending on their own interpretations they like. According to the guide books, there was a authoritive interpretation that simultaneous operation of osteotomy and tendon transfer for cerebral palsy and flat foot can be eatimated as 'osteotomy+JA-93-NA'. Conclusion: Distal soft tissue procedure should be approved as 'JA-93-NAx100%+JA-31x50%' according to the the estimated guide and authoritive interpretation if transected adductor hllucis is transfered to first metatarsal head. So distal chevron osteotomy could be 'JA-30-1-RAx100%+JA-31x50%', proximal metatarsal osteotomy could be 'JA- 93-NAx100%+JA-31-50%+JA-30-1-RAx50%', first metatarsocuneiform joint arthrodesis could be 'JA-93-NAx100%+ JA-31x50%+JA-73-RAx50%'.

Background: The aim of this study was to analyze the questions in the shoulder and elbow section of the Korean Orthopaedic In-Training Examination (KOITE) and compare them with those of the US Orthopaedic In-Training Examination (US OITE). Methods: Twenty-nine questions in the shoulder and elbow section of the KOITE from 2010 to 2014 were analyzed and compared with those of the US OITE (80 questions) by literature review. A thorough analysis of the contents was performed after categorizing as topics, diagnostic tools, treatment modalities, taxonomic classification, and references. Results: The shoulder and elbow section of the KOITE was 5.8% weight which was similar to the US OITE (5.9%). The most commonly appearing topic was anterior labral injury (17.2%) on the KOITE compared to instability and arthritis (21.3%, each) on the US OITE. Magnetic resonance imaging was most frequently appeared imaging modality on the KOITE (41.0%) compared to the radiograph on the US OITE (43.0%). The Latarjet procedure was the most commonly asked treatment modality (22.2%) on the KOITE, whereas arthroplasty (33.3%) on the US OITE. The KOITE showed an even taxonomic classification distribution compared to the US OITE. Campbell's operative orthopaedics covered 96.6% questions as a reference on the KOITE compared to the Journal of Bone and Joint Surgery, American Volume on the US OITE, which covered 45.0%. Conclusions: This specific analysis shows us current trends of the shoulder and elbow section of the KOITE and it might be developed for use in the educational curricula for the trainee.

Background: Recent studies have reported high rates of recurrence of shoulder instability in patients with glenoid bone defects greater than 20% after capsulolabral reconstruction. The purpose of the present study was to evaluate the failure rate of arthroscopic capsulolabral reconstruction for the treatment of anterior instability in the presence of glenoid bone deficits >20%. Methods: Retrospective analyses were conducted among cases with anterior shoulder instability and glenoid bone defects of >20% that were treated by arthroscopic capsulolabral reconstruction with a minimum 2-year follow-up (30 cases). We included the following variables: age, bone defect size, instability severity index score (ISIS), on-/off-track assessment, incidence recurrent instability, and return to sports. Results: The mean glenoid bone defect size was 25.8%±4.2% (range, 20.4%-37.2%), and 18 cases (60%) had defects of >25%. Bony Bankart lesions were identified in 11 cases (36.7%). Eleven cases (36.7%) had ISIS scores >6 points and 21 cases (70%) had off-track lesions. No cases of recurrent instability were identified over a mean follow-up of 39.9 months (range, 24-86 months), but a sense of subluxation was reported by three patients. Return to sports at the preinjury level was possible in 24 cases (80%), and the average satisfaction rating was 92%. Conclusions: Arthroscopic soft tissue reconstruction was successful for treating anterior shoulder instability among patients with glenoid bone defects >20%, even enabling return to sports. Future studies should focus on determining the range of bone defect sizes that can be successfully managed by soft tissue repair.

Purpose : To report a short-term clinical results and technical method of thermal shrinkage with radiofrequency device for anterior and posterior cruciate ligament laxity which is not suitable to indications of reconstructive surgery. Materials and Methods : Nine cases of anterior cruciate ligament injuries (ACL), 5 cases of posterior cruciate ligament (PCL) injuries and 3 cases of combined anterior and posterior cruciate ligament injuries, in which the condition is not indicated as reconstructive surgery, are investigated. The follow-up period averaged 6 months. Results : Instability in living activity, limping and pain were improved with excellent results. But, posterior cruciate ligament thermal shrinkage revealed as recurrent knee laxity progressively Conclusions : The result of thermal shrinkage for partial tear of cruciated ligament was excellent. We believe this procedure is applicable to partial tear of the ACL or PCL which reconstructive surgery is not indicated. Long-term follow-up results were needed.

Purpose: The objective of this study was to confirm the results of the modified Lapidus procedure on moderate to severe hallux valgus patients with first tarso-metatarsal joint hypermobility. Materials and Methods: A retrospective study was conducted on 42 cases of 35 patients who underwent the modified Lapidus procedure between March 2006 and December 2014. A comparative analysis was performed on the preoperative and postoperative subjective satisfaction of patients and radiologic index. Moreover, the correlation between the follow-up time and patient's operative satisfaction, as well as between the proficiency of the operator and patient's operative satisfaction was analyzed. Complications were also evaluated. Results: Out of the total of 35 patients, 3 were male and 32 were female. The mean age was 61.3 years (range, 34~79 years), and the mean follow-up time was 22.1 months (range, 6~90 months). The overall satisfaction level was 67.6% and the mean hallux valgus angle improved from preoperative $40.5^{\circ}$ to postoperative $12.2^{\circ}$ (p<0.001). The mean 1, 2 intermetatarsal angle improved from preoperative mean of $16.9^{\circ}$ to postoperative mean of $7.6^{\circ}$ (p<0.001), and the sesamoid position improved significantly, from preoperative 2.7 to postoperative 0.9 (p<0.001). Furthermore, there was no correlation between the follow-up time and the American Orthopaedic Foot and Ankle Society (AOFAS) hallux scale; also no correlation between the year the operation took place and the AOFAS hallux scale. In terms of complications, we observed screw irritation in 6 cases, hallux varus in 2 cases, and recurrence of hallux valgus and nonunion in one case. Conclusion: Contrary to our concerns, the level of complications was not high; however, the satisfaction level of patients was also not very high. Therefore, careful selecting of patients and sufficient consultation time is needed before surgery. In addition, since the causes of postoperative dissatisfaction still remain unclear, further studies are necessary.

Purpose: The purpose of this study is to report the preliminarily result of the radiologic disappearance of the calcific material, regardless of the size, type or location, on one-time ultrasonographic (US) assisted needling for calcific tendinitis of the shoulder. Materials and Methods: From March to August 2011, 46 patients (47 shoulders) with symptomatic calcific tendinitis were treated by one-time US assisted needling. Initially, a diagnostic US was performed with patient to determine the locations, numbers and sizes of calcific deposits. After 1% lidocaine local anesthesia, the calcific material was punctured with an 18-gauge needle under US monitoring. If no calcific material was aspirated after 2 or 3 additional attempts, the deposits was performed multiple puncture to achieve decompression. And then all patients were performed subacromial corticosteroid injection. All patients were followed up 4 weeks after procedure. To assess the radiologic disappearance after one-time US assisted needling, simple radiographs of the treated shoulder were performed and size, dense, and morphology of the calcific deposits were compared with those in baseline radiographs. For clinical evaluations, visual analogue scale for pain and function (PVAS and FVAS), and American Shoulder and Elbow Surgeons (ASES) score were assessed. Results: There were 11 male and 35 female patients with the mean age of 53.8 years (28-71). The morphology of the calcific deposits were 31 type A and 16 type B by French Arthroscopic Society classification and mean size was $2.9{\pm}6.7$ mm before the procedure. At 4 weeks after the index procedure, the radiographic unchanged group was included in 10 cases and changed group was 37 cases. No intergroup difference for the clinical results after the procedure was evident, but group FAS classification before the procedure was significantly different (p=0.011). Conclusion: At 4 weeks after one-time US assisted needling for calcific tendinitis of the shoulder, the radiographic size- or dense-changed cases were showed in 79%, regardless of the size, type or location of the calcific material. But the radiographic nearly or complete disappearance were showed in only 21%.

Lesions of the long head biceps tendon pulley are frequent causes of shoulder dysfunction and pain. These lesions cause instability of the long head of the biceps tendon (LHB), and intra-articular tear of the subscapularis and the supraspinatus tendon might result from them. The arthroscopic repair of these lesions has not gained widespread acceptance as an effective procedure. Predictable results can be obtained by treating these lesions more definitively with tenotomy or tenodesis. The purpose of this article is to review the anatomy and properties of the LHB pulley and to provide treatment strategies for alleviating pulley lesions.

Purpose: We had proceeded seven iIpsilateral dorsalis pedis vascularized pedicle flaps in the distal leg and foot to cover the restricted size defects and followed-up average for 5 years and 9 months to evaluate the survival rate, neurosensory function and cosmesis in final results. Materials and Methods: From January 1999 through October 2012, we have performed iIpsilateral dorsalis pedis vascularized pedicle flaps in the distal leg and foot to cover the restricted size defect (average around $3.6{\times}2.4cm$) in 7 cases and average age was 41.6 years (21.5 to 59.0 years). Lesion site was posterior heel in 4 cases, distal anterior leg in 3 cases. Donor structure was the dorsalis pedis artery and the first dorsal metatarsal vessel and deep peroneal nerve in 3 cases and the dorsalis pedis artery and the first dorsal metatarsal vessel in 4 cases. Results: Seven cases (100%) were survived and defect area was healed with continuous dressing without skin graft. The sensory function in the neurovascular flap was restored to normal in 3 cases. Cosmesis was good and fair in 7 cases (85.7%). Conclusion: Ipsilateral dorsalis pedis vascularized pedicle flap in the distal leg and foot is one of the choice to cover the exposed bone and soft tissues without microsurgical procedure.

Arthroscopic anterior cruciate ligament reconstructions using bone-patella tendon-bone have been considered the best method by which others are compared. The notchyplasty is one of the important steps of this procedure and it is emphasized recently to prevent retear of the reconstructed ACL caused by impingement. However, until now, there is controversy about adequate amount of notchyplasty. Also, it is hard to examine the adequacy of notchyplasty even in the arthroscopic field, The purpose of this paper is to describe the surgical technique of notchyplasty, using the flexible reamer and preliminary result of its operation. In this study the results of ACL reconstruction with notchyplasty which is made by us were analized from January. 1994 to December, 1995. The results were as follows: 1. The notchyplasty with flexible reamer is the method that can be obtained adequate amount of removal, perfectly smooth notchyplasty. 2. The range of motion of the affected knee joint was normal ROM after post operation 6 month. 3. In the last follow up, 2 cases were positive in anterior drawer test 4 cases were positive in Lachmann's test and 1 knee was positive in Pivot shift test 4. Average Lysholm knee scoring scale was 70 points at preoperative and 92 points at the last follow up.
