  • PURPOSES : The purpose of this study is to suggest the construction and quality control method for the re-repair of a deteriorated partial depth repair for sections of Portland cement concrete pavement. METHODS : An experimental construction was conducted to extend the repair width for removing an existing repair section. A removal method was used to ensure early performance for a deteriorated partial depth repair section. Bond strength and split tensile strength were measured at the near vertical interface layer between the existing pavement and repair material. The area was analyzed for various conditions such as the extended repair area and the removing method of the existing repair section. RESULTS : As a result of analysis of bond strength and split tensile strength, the bonding performance of a milling removed section was improved over a cutting and hand breaker removed section. The bond strength was analyzed to increase slightly as the extended repair width for removing the existing repair section increased. The split tensile strength did not show a clear relationship to an increased extended repair width of an existing removed repair section. CONCLUSIONS : The milling removal method should be applied in the removal of existing deteriorated partial depth repair sections. The extended repair width for a re-repair section should be wider than the existing partial depth repair with at least a 75-mm length and width for the bond strength and the split tensile strength.

  • Typically, massive rotator cuff tears have stiff and retracted tendon with poor muscle quality, in such cases orthopaedic surgeons are confronted with big challenging to restore the cuff to its native footprint. Furthermore, even with some restoration of the footprint, it is related with a high re-tear rate due to less tension free repair and less tendon coverage. In this tough circumstance, the partial repair has yielded satisfactory outcomes at relatively short follow-up by re-creating the transverse force couple of the rotator cuff. Through this partial repair, the massive rotator cuff tear can be converted to the "functional rotator cuff tear" and provide improvement in pain and functional outcomes in patient's shoulder.

  • Successful correction of the partial form of atrioventricular[AV] canal is now readily achievable. The most challenging technical features of this anomaly are the associated mitral valvular deformity and the frequent inability to obtain mitral competence. Residual mitral incompetence after repair of mitral cleft figures importantly in the causes of early and late failure. So, accurate and complete repair of the mitral valve cleft might be important. Determination of residual severe mitral regurgitation after repair is desirable to permit mitral valve replacement at the time. We have experienced one case of severe mitral regurgitation which was occurred 6 months after repair of partial form of A-V canal [ASD primum] in 22 years old virgin. Pre-op. left ventriculogram revealed severe mitral regurgitation in this patient. We preferred to perform mitral valve replacement with St. Jude valve in this patient at March 1984. Post-op. course was uneventful to now for 5 months and we report this case, review and discuss the literatures.

  • Fifty seven patients underwent repair of a partial atrioventricular septal defect from January 1980 to December 1986. The ostium primum atrial septal defect was closed with autologous or bovine pericardium. The cleft in the anterior mitral leaflet was present in 53 cases, absent in 4 cases. Of the 53 cases with a cleft in the anterior mitral leaflet, 48 received suture repair of the cleft, 3 received mitral valve replacement. There was no hospital death and all the patients were followed-up for a mean period of 26.4 months. Four required permanent pacemaker implantation due to complete heart block, and one of them died of sudden malfunction of pacemaker. Two received reoperation due to significant residual mitral insufficiency. Suture repair of the cleft in the anterior mitral leaflet resulted in significant decrease in degree of mitral regurgitation. During follow-up period 49 patients were in NYHA class I, 7 patients were in NYHA class II. This report suggests that excellent result can be achieved from repair of the partial atrioventricular septal defect by managing the left A-V valve as a bileaflet structure.

  • 내측으로 퇴축된 대범위 이상의 회전근 개 파열은 대범위 파열과 광범위 파열, 봉합이 불가능한 파열을 포함한다. 봉합 이 가능한 경우 일반적으로 사용되는 관절경 하 봉합술이나 개방적 봉합술을 시행할 수 있다. 그러나 관절경 감시하의 봉 합법은 무척 인내를 요하며 장기간의 긴 학습곡선을 필요로 한다. 봉합이 불가능할 경우에는 관절경 하에서 변연절제술(debridement)이나 부분 봉합술(partial repair)을 시행할 수 있고, 때로 광배근 이전술이나 역형 인공관절술을 시행할 수 도 있다. 관절경 하에서 변연절제술(debridement)은 국소 마취제의 견봉하 주사후에 통증의 완화와 운동범위의 향상을 경험한 환자들에게 일시적인 호전을 얻을 수 있다. 역시 봉합이 불가능 할 경우에 관절경하에서의 부분 봉합술(partial repair)을 시행하여 좋은 결과를 얻을 수 있다. 상견갑 신경의 신연에 의한 생리적 신경차단(suprascapular nerve traction neurapraxia)이 있는 경우에 특히 좋은 결과를 얻을 수 있다. 건 이식은 수평까지 어깨를 들어 올릴 수 있을 정도의 경도에 서 중등도 근력 약화의 경우에 장기적인 치료로 사용될 수 있다. 전상방 회전근 개 파열에 대하여 대흉근(Pectoralis major sternal head)의 근 이전술이 사용될 수 있으며, 후상방 회전근 개 파열의 경우에는 광배근(Latissimus dorsi) 근 이전술이 사용되고 있다. 역 견관절 치환술(Reverse Shoulder Prosthesis)은 어깨 관절의 근력이 극도로 약화된 가성 마비 (pseudoparalysis)에서 유용한 치료로 사용될 수 있다. 저자들은 내측으로 퇴축된 대범위 이상의 회전근 개 파열에서 관절경하 봉합법의 시행에 대하여 고찰하고자 하였으며, 봉합이 불가능한 파열의 경우에 변연절제술, 부분 봉합 및 건 이전술과 역 견관절 치환술의 이용에 대하여 고찰하고자 하였다.

  • Purpose : To compare and analyze the results of arthroscopic subacromial decompression and rotator cuff repair between partial rotator cuff tear and complete rotator cuff tear. Material and Methods : The authors studied 42 patients of rotator cuff tear with operation and followed over one year at Dankook university hospital from September, 1998 to March, 2001 The patient average age is 53 years and follow up period is 23 months (12-42mon1hs). We obtained 22 cases in the partial rotator cuff tear group and 20 cases in the complete rotator cuff tear group. In all cases, we used ASES methods to evaluated pain scale and function. Result : In the last follow up patients, the pain scale is decreased from 7.2 to 0.9 (ASES method : 34 to 91) in the partial rotator cuff tear group and from 7.6 to 1.2 (ASES method . 29 to 88) in the complete rotator cuff tear group, but there was no evidence of statistical difference between two groups (P>0.05). The range of motion after operation were increased in two groups. Excellent to good results were obtained 93% and 95% patients had pain relief and satisfied function. Conclusion : Arthroscopic subacromial decompression and arthroscopic rotator cuff repair showed good results for both of (ult-thickness and partial thickness rotator cuff tear patients in pain relief and improving the function.
