견관절 전방 불안정성에서 관절와 및 상완골 결손이 동반된 경우 적절한 진단과 치료는 치료 결과에 직접적인 영향을 주므로 중요하다. 견관절 불안정성은 정적 및 동적 안정화 구조물의 손상으로 기인하며, 상완골 두감입 골절(Hill-Sachs 병변), 관절와 골절이나 전하방 관절와 가장자리의 소실 등 정상적인 관절의 해부학 구조물을 훼손시키는 골성 이상 소견이 동반되면 경우에 따라 견관절 불안정성에 영향을 끼칠 수 있다. 본 강좌에서는 견관절 전방 불안정성에서 동반된 관절와 및 상완골의 골 결손에 대하여 논하고자 한다.

관절와 병변은 급성 외상으로 인한 골절뿐 아니라 불안정성으로 인한 골 침윤으로 정의할 수 있으며, 이는 통상의 방사선학적 검사를 통하여 진단을 하지 못하는 경우도 있다. 전방 탈구와 동반된 전방 관절와 골절의 빈도는 5.4%에서 32%까지 보고되었다. Hovelius 등이 226명의 탈구환자를 대상으로한 연구에서 8%의 관절와 골절이 있었다고 보고하였고, 노령의 환자에서 약간의 빈도가 증가한다고 하였다. 또한 Rowe는 전방 관절와 골절이 있는 27명의 환자에서 기계적 안정성의 결함으로 62%의 재발성 탈구가 있었다고 보고하였다. 보다 최근의 방카르트 술기에 대한 보고에서 수술적 처치를 한 환자중 44%가 관절와 골절을 동반하였다고 보고하였다. Rowe 와 Zarins는 다발성 전방탈구 환자에서 관절와 병변이 잘 치료되었는지 여부에 따라 다른 결과를 낸다고 보고하였다. 전자에 따르면, 관절와 병변을 진단하는 것은 중요하며 환자의 최종적 예후는 이를 어떻게 치료했는지 여부에 따라 결정된다고 하였다. 관절와 상완관절의 불안정성에서 동반된 관절와 병변의 진단은 보존적 치료시나 수술적 치료 시 모두 중요한 인자라고 하겠다.

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: The purpose of this study was to evaluate the radiologic and clinical outcomes after operative treatment using endobuttons for unstable distal clavicle fractures. Materials and Methods: Between October 2007 and September 2009, 9 consecutive patients who were followed up for at least more than 12 months after operative treatment using a TightRope$^{(R)}$ were studied. The radiologic results on the serial plain radiographs and the clinical results according to the American Shoulder Elbow Surgeons (ASES) score were analyzed. Result: Bony union was shown in 8 cases (88.9%) and the average time to union was 12.9 (range: 9~16) weeks. The average coracoclavicular distances at the postoperative and final follow-up were 5.6 mm and 6.2 mm, respectively, with no statistically significant difference (p>0.05). The average ASES score was 90.3 (range: 78~96) and the clinical outcomes were 6 excellent, 2 good and one fair. There were no complications such as implant failure or infection except for one case of nonunion due to loss of the initial reduction. Conclusion: A major advantage of TightRope$^{(R)}$ fixation for unstable distal clavicle fractures is that no further surgery is needed to remove the implant. We suggest that this technique provides an alternative for fracture with a distal fragment, which is difficult to fix.

Purpose: Bipolar hemiarthroplasty is used as an alternative to open reduction and internal fixation for unstable intertrochanteric fractures in elderly patients. Recent advances in medical systems and technologies have resulted in increased survival rates after intertrochanteric fractures of the femur, requiring selection of the appropriate femoral stems considering the mid- to long-term duration of survival. Hemiarthroplasty was performed for unstable intertrochanteric fractures using a double tapered quadrilateral femoral stem (C2 stem), and the clinical and radiological results were evaluated as a five-year follow-up post-surgery. Materials and Methods: From January 2004 to December 2013, 43 patients (43 hips) who underwent hemiarthroplasty with a C2 stem were enrolled in this study. Their mean age was 78.6 years (range, 70-84 years), and the mean follow-up period was 85.4 months (range, 60-96 months). During the follow-up period, clinical parameters, such as the changes in pain, walking ability, and functional status, were examined. Radiologically, changes in the proximal femur, such as osteoporosis and bone resorption of cortical bone, were noted. Complications that occurred during the follow-up period, such as dislocation and prosthetic features, were also reviewed. Results: Initially, the pain was relieved postoperatively, but it increased four years after surgery. The walking ability was reduced by two steps in nine patients after 60 months, and the Harris hip score was reduced significantly postoperatively after two to three years. Radiologically, cortical osteoporosis occurred in 14 patients. Five patients developed cortical bone resorption. Four of them showed nonunion of the trochanteric fracture fragments, and three of them suffered reverse oblique fractures. Conclusion: Careful selection considering the general health condition and remaining lifespan of the patient would be necessary for primary hip hemiarthroplasty using a 3C type cementless femoral stem for unstable intertrochanteric fractures in elderly patients with osteoporosis.

Purpose: To review the clinical and radiological results after an open reduction and internal fixation with a T-shaped LCP for unstable distal clavicle fractures. Materials and Methods: From February 2005 to June 2006, ten patients with distal clavicle Neer type II fractures were treated with an open reduction and internal fixation with a T-shaped LCP. Bony union was identified by plain radiography. The clinical results were analyzed according to the UCLA scoring system. Results: The mean time to fracture union was 9weeks and union was achieved in all cases. The mean UCLA score was 33.4 (30-35); excellent in 8 cases and good in 2 cases. In one case, loosening of one distal screw was occured and mild AC joint subluxation was observed in another case. Conclusion: 3.5 mm T-shaped LCP fixation is a useful technique for treating unstable distal clavicle fractures. This procedure provide stable fixation with no further AC joint injury.

Purpose: To evaluate and report the clinical and radiological outcomes of open reduction and internal fixation with a mini-T plate for unstable distal clavicle fractures. Materials and Methods: From December 2004 to July 2007, fifteen patients who had a fracture of the distal clavicle (Neer type II fracture) were treated with an open reduction and internal fixation using a mini-T plate. They were followed up for a minimum of one year and the clinical and radiological results were analyzed. Results: The average time to fracture union was 3.1(3~4) months. There were no complications, such as deep infection or fixation loss. The mean ASES score was 97 points (85~100points) at the last follow up period, and 14 patients had a full range of motion of the shoulder. Conclusion: Open reduction and internal fixation with a mini-T plate for unstable distal clavicle fracture is a good surgical method with good clinical and radiological results.

Posterolateral rotatory instability is the most common pattern of elbow instability especially which is recurrent, and is usually post-traumatic because of inadequate soft tissue healing. The lateral ulnar collateral ligament was reconstructed by using ipsilateral palmaris longus tendon. Functionally good result was obtained. This is a case report illustrating the posterolateral rotatory instability of the elbow and its reconstruction with palmaris longus.

Background: We analyze the functional evaluation, posterior stability after surgery of acute injuries in the femoral detachment and tibial avulsion fracture of posterior cruciate ligament. Materials and Methods: Twenty two patients who underwent primary repair were followed more than one year after operation (mean follow-up 33.7 months). The patients were evaluated with KT 2000 arthrometer and posterior stress test for posterior stability. Lysholm knee score was used for knee function. Results: Lysholm score revealed 85.3 in femoral detachment group and 91.1 in tibial avulsion fracture group (P<0.05). Posterior displacement of the posterior stress test showed 17.2 mm at initial injury and 8.6 mm at last follow up in femoral detachment group, 16.8 mm at initial injury and 7.1 mm at last follow up in tibial avulsion fracture group. There revealed the tendency of the improved posterior stability of the tibial avulsion group compared with femoral detachment group, but there showed no statistical significance in KT 2000 arthrometer and posterior stress x-ray. Conclusion: Functional results of tibial avulsion fracture group revealed the better outcome compared with femoral detachment group, but the degree of posterior stability in tibial avulsion fracture group showed no statistical significance in posterior stability.
