The problems of L / 대한정형외과학회잡지

Owing to the advancement of imaging techniques which include the CT scan, it became easier to evaluate fracture patterns of calcaneal fractures accurately. Moreover, it is possible to obtain good results with operative treatment as a consequence of the development of good operative equipment and new operative technique. In 1988, Regazzoni and Benirschke in 1990, recommended L-shaped extensive lateral approach for calcaneus which provide extensive exposure of calcaneus and so allow easier reduction and fixation. We carried out L-shaped extensive lateral approach in 11 cases from June, 1993 to April, 1994. This approach did not produce any skin problems and allowed excellent anatomical reduction and fixation. But we experienced some severe causalgia on the heel region in several cases. We tried to analyse the cause of pain and concluded that it was the damage to the lateral calcaneal branch of the sural nerve. We are reporting the problems of tbis approach.

Arthroscopy-assisted Reduction and Fixation in Fracture of Proximal tibial Condyle / 대한정형외과학회잡지

In the treatment of proximal tibial condyle fracture, it should be considered that it can often accompany injuries of the collateral ligament, both cruciate ligament, and the menisci of the knee. Moreover it is necessary to restore anatomical congruity of the articular surface accurately. We performed reduction of the depressed articular fragment under monitoring of arthroscopy and fixed with cannulated cancellous screws and accompanied by bone graft under the control of image intensifier in 2 cases of Type I(Pure cleavage) and 3 cases of type II(cleavage with depression) fractures. The results were very satisfactory. Arthroscopy assisted reduction and fixation are very useful method in the treatment of proximal tibial condyle fracture because of (1) the minimized operative morbidity, (2) the ability to evaluate and manage associated intraarticular pathology simultaneously, (3) the rapid rehabilitation, (4) the achievement of good reduction comparable to open reduction.

The Effect of Augmentation with The Synthetic Polyester Ligament in Aculte Tear of The Anterior Cruciate Ligament Preliminary report / 대한정형외과학회잡지

The development of the arthroscopic surgery technique presented a great method in the reconstruction of anterior cruciate ligament. There were many debates about the timing of reconstruction in the acute anterior cruciate ligament injury. However, it was regarded true that primary reconstruction in the acute phase have higher complication rate of arthrofibrosis than in the chronic phase. Many authors recommended delay of reconstruction at least 3 weeks in acute tear of anterior cruciate ligament. In contrast, some surgeons have tried to suture the ruptured anterior cruciate ligament accompanied by 'over-the-top' augmentation with the hamstring tendon or the artificial ligament arthroscopically. Since Jan. 1992, the authors have implanted the synthetic polyester ligament(ABC ligament; Surgicraft, U.K.) into the substance of ruptured ligament proper and fixed at the 'over-the-top' position without any procedure for repair of the ruptured anterior cruciate ligament. Our indication for this surgery is only acute rupture of anterior cruciate ligament with good stump condition. We report the clinical results of 22 cases at 20.3 months follow-up(mean) preliminarily. l. On measurement of pre-operative and post-operative differences between the normal and the affected side by Telos stress X-ray study and KT-2000 arthrometer. Differences were markedly improved from 5.6mm(mean: pre-op) to 1.9mm(mean: post-op) on Telos stress X-ray study(on 15 Kp stress) and both knee showed minimal differences on KT-2000 study(2.2mm on 9Kp, 2.5mm on maximum stress) at the time of follow-up. 2. The average Lysholm score was 82. By Clancy criteria, the 20 cases(91%) showed good and excellent results. 3. Second look arthroscopy was available in three cases. In two cases, there were marked fibrous proliferation around the ligament. The stability felt good on probing. We could observe healing-like appearance of ruptured ACL with minimal fibrous tissue proliferation in one another case.
