Purpose: We evaluated the correlation of postoperative clinical outcomes and radiologic findings using computed tomography and simple X-ray in intra-articular calcaneal fractures. Materials and Methods: The current study is based on 41 feet, 38 patients with displaced intra-articular fracture who underwent surgical treatment with at least one year of follow-up. Evaluation of clinical outcome included American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS) score, and subjective satisfaction. A simple X-ray was used in evaluation of preoperative and postoperative Gissane angle, B${\ddot{O}}$hler angle, and calcaneal fracture width. Computed tomography scan was performed for evaluation of preoperative and postoperative articular step-off and articular gap in all cases. Finally, we evaluated the correlation of the postoperative clinical outcomes and radiologic findings based on the measurement. Results: The average postoperative AOFAS score and VAS score was $84.1{\pm}8.5$ and $2.2{\pm}2.2$. Subjective satisfaction was excellent in 15 cases, good in 19 cases, and fair in seven cases. The average B${\ddot{O}}$hler angle was restored from $11.1^{\circ}$ to $24.7^{\circ}$(p<0.05), Gissane angle was changed from $121.0^{\circ}$ to $119.0^{\circ}$ (p>0.05), and the average width was restored from 45.8 to 35.0 mm (p<0.05). The average articular step-off and gap were decreased from 6.3 to 2.0 mm and from 11.1 to 4.6 mm, respectively (p<0.05). No significant correlations were observed between the clinical outcome and Gissane angle, B${\ddot{O}}$hler angle, and width, and there was no significant correlation between the clinical outcome and Sanders classification. However, postoperative articular step-off showed correlation with VAS and AOFAS score and articular gap showed correlation with VAS score. Conclusion: The clinical outcome did not show correlation with B${\ddot{O}}$hler angle and Gissane angle but did show correlation with anatomical reduction of the posterior facet joint.

We treated 10 cases of the medial malleolar fracture of the ankle by open reduction and internal fixation from June 1997 to December 1997. After the rigid internal fixation, we measured the gap of the fracture site and the step off of the articular surface by special instrument under the ankle arthroscopy whether it was reduced anatomically or not. And we tried to know the necessity of the arthroscopically assisted reduction and fixation in the medial malleolar fracture of the ankle. Under the arthroscopic view, all 10 cases were anatomically reduced as less than 1 mm of gap of the fracture site and less than 1mm of step off of the articular surface after open reduction and internal fixation in the medial malleolar fractures. In conclusion, through the arthroscopic management, it has advantage in finding and treating the accompanying intraarticular lesion, but also has disadvantage in setting the arthroscope and prolonging the operation time.

Purpose: The purpose of this study is to evaluate the effectiveness and indications of the modified Essex-Lopresti reduction in calcaneal fractures. Materials and Methods: We reviewed retrospectively 41 cases of displaced intraarticular calcaneal fractures. The fracture was reduced with Essex-Lopresti technique with modification in compression of the lateral wall with the specially designed compression device instead of the operator's hands. We evaluated the results of treatment by AOFAS scale and the radiographic parameters including the Bohler's angle, calcaneal width, calcaneofibular distance and the congruency of the posterior facet. Results: Boler's angle was restored from 11 to 29.6 degrees on average, heel width was reduced to 112% of contralateral value, the calcaneofibular gap was restored up to 87.9% of contralateral side, and the articular surface of the posterior facet was restored less than 2 mm of step off and less than 2 mm of gap. AOFAS scale averaged 87 points. The quality of reduction was best in Sander's type II fractures. Small sized fragments in type III fractures could not be reduced. The results were better when the reductions were performed within 24 hours of injury. Conclusion: The modified Essex-Lopresti reduction was less invasive, easy to perform, and the results of treatment were similar to those of open reduction; it seemed to be a reasonable alternative for the selected intraarticular calcaneal fractures.

Purpose: To report the clinical result of the intraarticular calcaneus fracture after open reduction and internal fixation with plate by lateral approach. Materials and Methods: Thirty-six calcaneal fractures of 33 patients(29 men and 4 women) were treated by open reduction and internal fixation using an lateral approach from March, 1997 to May, 2002 and were followed more than one year. The autogenous iliac bone graft was done in 2 cases but the others didn't. Radiographically B?hler angle and Gissane angle on simple lateral radiograph were measured and in the 15 cases, the step-off(gap) of posterior facet joint on post-operative CT images were followed. The Salama method was used for evaluation of clinical results. Results: According to Sanders classification, 19 cases of the 36 cases were classified as type II. Type III fracture were found in 12 cases and type IV in 5 cases. The following results were obtained: twenty-two cases(61.1%) out of 36 cases were estimated as good or excellent. The good results or more were obtained in 15 cases(78.9%) in type II and 7 cases(58.3%) in type ill, but no case in type IV. B?hler angles were improved from preoperative average 1.6?to postoperative average 23.4?, Gissane angle was improved from preoperative 107.2?to postoperative 122.8?, respectively. Among 36 cases, Computed tomography was carried out in 15 cases. The postoperative step-off (gap) of posterior facet joint on computed tomography was filled with cancellous bone. Satifactory results was obtained in 7 cases with 2mm gap or less and in 6 cases of 2-5mm. There were no satifactory results in 2 cases with 5mm gap or more. Conclusion: Open reduction and internal fixation for intra-articular fracture of calcaneus was thought to be a good treatment modality. It is thought that the lateral approach is one of the good one for surgical treatment, and that accurate reduction of the posterior facet, acceptable recovery of B?hler angle are more important to obtain best results.

Purpose: This study was performed to analyze the characteristics of calcaneocuboid joint involvement in intraarticular calcaneal fractures. Materials and Methods: Total number of 92 patients (111 cases) who underwent operation for intraarticular calcaneal fractures between Jan. 2000 and Oct. 2005 were included in this study. The preoperative computed tomographs of the subjects were retrospectively reviewed to analyze calcaneocuboid joint involvement. Results: It was revealed that 63 cases (56.8%) involved calcaneocuboid joint; 29cases (46.0%) showed type 1 (undisplaced or minimally displaced type, articular gap ${\le}1\;mm$), 16 cases (25.4%) exhibited type 2 (moderately displaced type, articular gap ${\ge}2\;mm$), 7 cases (11.1%) were included in type 3 (comminuted type) and 11 cases (17.5%) belonged to type 4 (fracture and dislocation). 48 out of 63 cases belonged to Sanders classification II and III that involved calcaneocuboid joint and included 25 cases (52.1%) of type 1 and 14 cases (29.2%) of type 2. Among 15 out of 63 cases included in Sanders classification IV, 4 (26.7%) showed type 1 and 6 (40.0%) belonged to type 4. According to our results, Sanders classification allowed to predict pattern of the involvement of calcaneocuboid joint (P<0.05). However, there was no statistically significant relationship between degree of posterior facet joint injuries and calcaneocuboid joint involvement (P>0.05). Conclusion: Calcaneocuboid joint involvement in intraarticular calcaneal fractures was common and more than half showed severe injuries. We concluded that further studies on the involvement of calcaneocuboid joint should be performed prior to surgical treatment of intraarticular calcaneal fractures.

The sacrum fused with ilium in a chinese water deer (Hydropotes inermis) was observed. The sacrum consists of four sacral vertebrae which was fused each other. In the ventral part of the fused pelvis, on the left, there was a 20.19 mm gap at the dorsolateral part of the sacroiliac articular part which is in between the promontory and the cranial border of the first ventral sacral foramen. On the right, there was a 14.34 mm gap at the dorsal part of sacroiliac articulation. In the dorsal view of the fused pelvis, the wing of sacrum and the wing of ilium were fused tightly, so that the boundary of the two bones was not recognizable. The left and right second dorsal sacral foramina and the third dorsal sacral foramen on the left were small. The third dorsal and ventral sacral foramina on the right were not formed.

In order to improve static stability and healing of reattached labrum, we combined the advantages of suture bridge and transosseous technique. Using the conventional 3 portal for anterior instability, check stability of bony Bankart and preparation of glenoid bed in 3 way including removal, reshaping or mobilization of bony fragment. Two anchors were inserted to the superior and inferior portion and medial edge of bony Bankart lesion. It usually corresponded to the area of IGHL. Medial mattress sutures were applied around IGHL complex to get enough depth of glenoid coverage using suture hook. Make 3.5mm pushlock anchor hole to the articular edge of glenoid cartilage. Proximal suture bridge was applied at first and then distal suture bridge was inserted to mobilize the labrum in proximal direction. These construction can provide more stable labral repair with wide contact and compression in case of deficient bony stability. It not only avoids technical disadvantage of point contact with anchor fixation, but also decreasing gap formation through cross compression of labrum that couldn't gain even with the transosseous fixation which affords linear compression effect. Additional bony stability could be gained if the the bony fragment was mobilized to the glenoid margin with potential healing bed or reshaped for the good contact with reattached labrum.

목적: 슬관절의 연골 결손에 대한 미세골절술 후 병변을 덮는 생체막을 이용한 환자들의 치료 결과를 비교, 분석하고자 한다. 대상 및 방법: 2008년 1월부터 2010년 1월까지 관절경 검사로 확인된 슬관절 연골의 국소적 전층 결손이 있으며, 골관절염을 보이지 않는 53명(총 59례)의 환자를 대상으로 하였다. 무작위로 선정된 36명(42례)은 미세골절술 후 생체막으로 병변을 덮어주었고(실험군), 나머지 17명(17례)은 고식적인 미세골절술만을 시행받았다(대조군). 모든 환자는 수술 후 6개월째에 임상적 결과를 IKDC 설문지와 통증, 만족도에 대한 VAS 점수를 이용하여 비교하였고, 자기공명영상 촬영을 통해 골연골 병변의 회복 상태를 비교하였다. 결과: 임상 결과(IKDC, 통증 VAS, 만족도 VAS)에서 실험군이 대체로 더 우수하였으며 IKDC에서는 두 군 간의 통계적으로 유의한 차이를 보였다. (IKDC, p=0.047, 통증 VAS, p=0.074; 만족도 VAS, p=0.001). MRI 추시결과에서 실험군의 33명(78.6%)에서 우수한 결손 치유(67~100%)를 보이고, 5명(11.9%)만이 불량한 치유 소견을 보인 반면, 대조군에서는 4명(23.5%)의 환자에서 양호한 결손 치유가 관찰되고 9명(52.9%)의 환자들에서 결손 치유가 불량하였다(p=0.001). 실험군에서 35명(83.3%), 대조군 중 6명(35.3%)에서 변연부 결합부에서 간격이 관찰되지 않았다(p=0.001). 생체막 사용과 관련하여 심각한 부작용은 발견되지 않았다. 결론: 슬관절의 연골 결손 병변에 대해 미세골절술 후 생체막으로 도포한 군에서 단기 추시 임상적 결과 및 MRI를 이용한 영상학적 결과에서 결손부의 연골재생이 잘 된 것을 확인하였고, 미세골절술 후 ArtiFilm$^{TM}$을 함께 사용했던 군에서 연골 치유가 더 잘되는 경향이 있음을 시사한다.
