An automated percutaneous lumbar discectomy(APLD) have been apphed for contained lumbar disc herniation. But suggested that more exclusion criteria than disc containment was needed to improve success rate. The purposes of this study are to evaluate cIinical outcome of more than 4 years follow up of APLD, to analysis the cause of failure for longer follow up period, and to define prognostic factor of APLD. The l04 patients with contained lumbar disc herniation were treated with APLD from March 1990 to November 1992 in National Medical Center. The surgical candidates were contained focal disc herniation in MRI, sciatica than back pain, failure to conservative management at least 6 weeks and clinical and radiological correlation. And patient were excluded from this data if they had history of previous lumbar surgery and compensation claims. Among them 74 cases were followed up for over 4 years (Mean: 5.3 years). The results were accessed by questionnaire using telephone or OPD follow up. The overall success rate was 84% on 3 months follow up, but 68.9% on more than 4 years follow up by four subjective criterias (Onik, 1987). Causes of decreasing success rate were reoperation, recurrence without specific cause or after sprain and heavy work. 76% of failed cases occurred within 1 year and 40% of them underwent open discectomy. The patient sex, treated level, duration of symptom were not influenced on success rate, but age was factor related to success rate. In this study we can assess the effectiveness of APLD within 3 months in most cases and then change treatment option according to patients status, and it seems that we need more exclusion criteria than disc containment in MRI and refined patient selection in order to decrease the failures.

The transpedicular screw fixation is known to be capable of providing more secure correctional, force and rigid fixation to the spine. But it is often accompanied by various complications, including stress shield effects, loosening in osteoporotic spine, pseudoarthrosis, hardware problems and long-term change in motion behaviors at the adjacent motion segment and etc. The purpose of this study is to compare the flexible and rigid rods system in terms of complications and problems for various degenerative lumbar diseases. From September 1991 to November 1994, 41 patients were operated with the flexible rods system (group A) and 39 patients with the rigid rods system (group B). They were followed up for more than 4 years. The flexible rods system was composed of 41 cases of Wiltse system and the rigid rods system was composed of 29 cases of Diapason, 8 cases of TSRH and 2 cases of CD instrument. The resuits of the study were as follows: 1. By standard Cobb lateral measurement, 7 cases in group A and 10 cases in group B showed significant loss of sagittal angle (>4), post-operatively. 2. Hardware failure was noted in 7 cases in group A and 10 cases in group B. In group A, rod bending was seen in 4 cases, rod breakage in 2 and screw loosening in one. In group B, screw loosening was observed in 5 and screw-rod locking mechanism failure in 5 cases. 3. In spondylolisthesis patients, 10 cases in group A and 14 in group B, there was no statistically significant differences between the two groups in the reduction rate immediately after surgery and loss of reduction at the last follow up. 4. Clinical results were good to excellent in 85.4% of patients in group A and 82.1% of group B. No statistically significant differences between the two groups were found, 5. No statistically significant differences between the two groups were found with respect to degenerative changes at the adjacent motion segment to the fused level and pseudoarthrosis.

The first metacarpal base fracture is classified as extra-articular fracture, intra-articular fracture and epiphyseal injury. Intra-articular fracture was firstly described in 1882 by Bennett and Rolando described about Y shape comminuted fracture in the first metacarpal base in 1910. In 1938, Robert wrote about oblique fracture injured by first metacarpal base fracture. First metacarpal base fracture can be adjusted easily by C/R, but it is difficult to maintain the good axis. In case of fail of reduction, malunion, joint stiffness and traumatic arthritis can be shown as complications and finally some problems in grasping and pinching are resulted. Therefore, firstly the most accurate reduction, secondarily effective method to maintain the condition and thirdly the protection of limitation of motion are goal of treatment. Authors reviewed 17 cases treated by 0/R & C/R for the past 5 years from 1975 to 1980 at National Medical Center, especially reviewed the cases of which observation more than 1 year was possible. The results were as followings: 1. The incidence of first metacarpal base fracture was 1.0% of all fractures & dislocations. 2. Out of 17 cases, there were 14 male and right side 9 cases and left side was 8 cases. 3. The most common case of fracture was injury at work and traffic accident, sports injury, slipping down and falling down. 4. The method of treatment were C/R & percutaneous pinning in 10 cases and 0/R & K-wire fixation were 7 cases. 5. The result of treatment showed 8 excellent, 1 good, 1 fair, out of 10 cases of C/R and percutaneous pinning. In 0/R and K-wire fixation, 4 excellent, 2 good, and 1 fair showed out of 7 cases. 6. Soft tissue infection was appeared from 1 case of open fracture which accompanied second metacarpal fracture as complication and it caused adduction contracture in first web space.
