Cephalometric prediction tracing is the preoperative double checking procedure which can predict bony and soft tissue change. Soft tissue profile prediction is routinely performed according to the known ratios of the soft to hard tissue movement which can vary considerably in each individual. Besides interindividual variation of the ratios of the soft to hard tissue change, actual results of the postoperative soft tissue profile can reflect other important modifying factors if it is compared with prediction tracing used. The purpose of this study is to compare soft tissue prediction tracing used with postoperative tracing and to find intervening modifying factor via serial tracing. Review of 30 prediction tracing showed that the most important factor contributing to prodiction tracing inaccuracy was the skeletal and dental relapse. And, some factors which may be responsible for prediction tracing inaccuracy were discussed.

Purpose: We evaluated the result of the degree of reduction and anterior instability after arthroscopic treatment of tibial spine fractures. Materials and Methods: Thirty-two cases of tibial spine fractures treated with arthroscopic procedure could be evaluated and the mean follow-up period was $18\;(12{\sim}48)$ months. Evaluations included Lachman test, rotatory instability examination and side to side difference (SSD) using KT-2000 arthrometer. The degree of radiologic reduction was classified as accurate reduction, anterior elevation and reduction failure, according to which the degree of anterior instability was measured. Results: There were twenty three cases (71%) of accurate duction, eight cases (25%) of anterior elevation and one case (4%) of education failure. Eight (29%) of twenty eight cases with pull-out method showed anterior elevation. The SSDs of the accurate reduction and the anterior elevation group were 2.0 mm and 2.8 mm, respectively showing no significant difference. However, the percent age of grade 0 Lachman test and SSD less than 3 mm of the accurate reduction group were significantly higher. Conclusion: Accurate reduction is important in reducing anterior instability especially in unstable fractures. Therefore, arthroscopic pull-out method should be performed with great caution to avoid anterior elevation of the fracture fragment.

Purpose: An osseous defect in the glenoid and humeral head is closely associated with recurrence of anterior shoulder instability. The purpose of this article is to describe the open surgical techniques and introduce our experiences with anterior instability with a significant osseous defect. Materials and Methods: We reviewed the articles that have focused on and/or mentioned the affect of osseous defects on anterior shoulder instability. The open surgical techniques and its related pearls are summarized in this review. Results: Accurate evaluation for the size and location of the osseous defect is critical for preventing recurrence after restoration of the anterior capsulolabral structure. The glenoid bone restoration techniques include the coracoids transfer (the Bristow procedure and the Latarjet procedure) and a structural iliac bone graft. Rotational humeral osteotomy and an osteoarticular allograft could be used for repairing a significant posterosuperior humeral defect (Hill-Sachs lesion). Shoulder arthroplasty may be tried for treating a humeral bone defect, but more study on this is needed. Conclusion: Open surgical restoration decreases the risk of recurrence anterior shoulder instability that is combined with a significant osseous defect. Arthroscopic surgery currently has limitations for treating an osseous defect, but it will become useful in proportion to the development of arthroscopic instruments and techniques in the future.

Purpose: The aim of this study was to evaluate the usefulness of arthroscopic Bony Bankart repair using a One Anchor Double Fixation Technique. Materials and Method: Seventeen patients with a Bony Bankart lesion were treated using the One Anchor Double Fixation Technique (OADF Technique). There were 13 males and 4 females. The average age was 24 years (range 17-42). The average follow-up period was 22.3 months. One 3.0 mm suture anchor with doubly loaded sutures was inserted into the glenoid rim. One suture strand was passed the around the small bony fragment and tied first. Another suture strand was passed through the capsule and tied over the bony fragment. The result was measured using Rowe's evaluation index & KSS score. The glenoid defect & bony fragment were measured by 3D-CT scan. Results: Rowe's evaluation index on the final follow-up showed an overall improvement from an average of 54 (range, 23-71) to 83.4 (range 71-90). Of the 17 cases, 13 were excellent, 3 were good, and 1 was fair. KSS scores showed improvement from an average of 71 (range 49-82) to 92.5 (range 82-94). There were no cases where pain continued to the final follow-up, and no cases being re-dislocated during the follow-up period. For six cases, we confirmed the bony healing of the bony Bankart lesion by CT. Conclusion: Bony Bankart lesion repair using this new method achieves excellent clinical results with low recurrence rates and is considered another choice for bony Bankart lesions.

At present trend 3D Printing technology has been using more efficiently than conventional subtractive manufacturing method in various medical fields, in particular this technology superior in saving production time, cost and process than conventional. Especially in orthopedics, an attractive attention has been paid by adopting this technology because of improving operation, operation accuracy, and reducing the patient's pain. Though 3D printing technology has enormous applications still in some hospitals have not been using due to having the problem of technical utilization of hardware, software & chiefly financial availability and etc. In order to solve these problems by reducing the cost and time, we have used CT images in pre-operative planning by directly making the pelvic fracture model with open source DICOM viewer and STL file conversion program, assembly 3D printer of FDM wire additive manufacturing. After having the customized bone model of six patients who underwent unstable pelvic fracture surgery, we have operated our system in orthopedic section of University Hospital through the clinician. Later, we have received better reviews and comments on utilization availability, results, and precision and now our system considered to be useful in surgical planning.

Recurrence is the most common complication after shoulder instability surgery, and the main causes of the postoperative recurrence of instability are trauma, misdiagnosis, and technical errors. The risk factors of recurrence may be classified as patient related, anatomical or technical. Causes of failure should be thoroughly evaluated by meticulous history taking, physical examination, and imaging studies, and followed by proper treatment of pathologic lesions. Nonoperative treatment should be considered initially in cases of recurred instability after shoulder instability surgery, but if this fails, repeated recurrence is prevented by performing appropriate anatomical reconstruction of ruptured Bankart lesions, capsular laxities, glenoid deficiencies and humeral head bone defects.

투구운동은 견관절에 반복적인 압박력 및 신장력을 가하게 되며 이는 견관절의 정적 안정력의 약화를 유발하게 된다. 초기의 경도의 불안정성은 근육 등 동적 안정력의 작용으로 안정적인 운동상태를 유지할 수 있으나 반복적인 운동이 지속될 경우 근육이 피로해 져서 동적 안정력의 보상작용을 통한 안정성을 얻을 수 없게 된다. 이는 일차적으로 견관절의 불안정성을 유발할 뿐만 아니라, 이차적으로 견봉하 충돌증후 및 내적 충돌증후 등의 증상을 나타내기도 한다. 과 투구로 인한 대부분의 운동손상은 보존적 치료로 좋은 결과를 볼 수 있으며, 이는 일차적으로 투구를 중지하여 관절을 안정시키며 진통 소염제나 물리치료 등을 통한 항 염증치료, 그리고 회전근개 및 견갑골 주위근육의 강화운동 등의 단계로 진행된다. 적절한 보존적 치료에도 불구하고 증상이 지속될 경우 정확한 진단에 근거한 수술적 치료 및 조절된 재활운동 프로그램을 통해 조기 운동 복귀를 기대할 수 있다.

Persistent instability following an acute lateral ankle sprain eventually require ligamentous reconstruction in some cases. Over 50 surgical procedures have been described to reestablish lateral ankle stability varying from direct in situ repair of the anterior talofibular ligament and the calcaneofibular ligament to augmented reconstructions with either autograft or allograft tissue. The author describes the rationale and the technique of anatomic ankle ligament reconstruction with the 4th extensor digitorum longus tendon.
