The patellar tendon is known as the strongest material for the substitution of anterior cruciate ligament. There are many technical difficulties in reconstruction of the ligament with this tendon since patellar aponeurosis is weak, and the length of the tendon is restricted, and the adquate insertion in proper place is difficult. Authors harvested the middle 1/3 of patellar tendon c bone block of tibial tubercle and patella with the superficial layer of the quadriceps tendon left attached. The large triangular tibial tubercle piece was impacted into the femoral tunnel from distally to proximally, of which the orifice is the very place of the middle of the original anterior cruciate ligament. Two bundles of 0-dexon sutures made at the tibial tubercle portion, were pulled through to different outlet of femoral condyle during this procedure and were tied over the cortical bone of lateral supracondylar region. The tendon twisted 180°(clockwise for the right knee and counter-clockwise for the left knee) to adapt to screwhome movement. The patellar piece was fixed at the isometric point in full flexion and extension, which is usually the middle point of original tibial insertion c one or two barbed staples made at the original position of tibial insertion of the ligament. We tried this methods in 26 knees (12 vascularized grafts and 14 free grafts) and was followed for more than one year and the results was compared with those of 12 knees of original McIntosh operation (follow up period: 16-72 months, average 34.3 months). The instability were evaluated c Lachman test and OSI sagittal knee tester. The knee of negative Lachman test & pivot shift test was defined as "normal" The results were as follows;l. In modified McIntosh operation group negative Lachman test was noted only in 6 knees (50.0 % ) and there were 2 knees (16.7% ) of GI, II & III, respectively. 2. In vascularized bone block patellar tendon graft group II out of 12 knees (91.7%) showed negative Lachman test and only one knee (8.3%) revealed G II. 3. In free bone block patellar tendon graft 13 out of 14 knees (92.9%) showed negative Lachman test and the other one knee (7.1%) revealed GI. 4, The overall success rate (normal) of bone block patellar tendon graft was 92.3%. The success rate of patellar tendon bone block operation was significantly higher than that of modified McIntosh operation (χ²=6.48, df=1, P=0.0109) and there was no statististical difference between vascularized and free graft group (χ²=0.39, df=l, P=0.5322).

Long segmental fixation with TSRH posterior instrumentation for 19 patients who had unstable thoracolumbar fracture was performed between October 1992 and April 1995. The patients were followed for an average of 22 months. Measurements of the deformity angle, kyphosis, vertebral height, and the intervertebral angle were made. The patients were divided into 2 groups according to configurations of instruments for lower segmental fixation. For one group, only hooks were used, and for the others group pedicular screws and lateral offset hooks were used together at the same segment. Therefore, the purpose of this study is to anlyze the correctability following long segmental fixation and to compare one segmental fixation using both screws and lateral offset hook systems with two segmental fixation using hook systems for distal fixation. There was an overall correction of kyphosis at follow-up of 6.9degrees (27.1%) after a loss of 4.3degrees from operative correction. Overall correction of deformity angle was 8.2degrees (32.2%). Loss of vertebral height at final follow-up was 4.4%. And loss of intervertebral angle was 2.0degrees at follow-up. There was no difference of overall results between the hook group and the pedicular screw with lateral offset hook group. However, there was a significant improvement of the correction of kyphosis and restoration of vertebral height in patients who underwent operation within 7 days after injury, as compared to delayed operation. Therefore, the timing of surgery is the most important factor in order to correct the deformity caused by unstable thoracolumbar fractures. There was no significant loss of correction and no metallic failure. Therefore, rodding long with the method of one segment distal fixation using screws and lateral offset hook together can provide excellent correctability, maintenance of correction, preservation of distal lumbar joints, prevention of implant failure and complication.

Between January 1994 and February 1996 lumbar fusion was carried out in eight patients who had degenerative lumbar disease by a technique of translaminar facet screw fixation. The goal of instrumentation is to confer immediate stability to unstable segments and lower the pseudarthrosis rate. However, transpedicular systems can carry a risk of neural damage and require a high standard surgical skills. Therefore, the purpose of this study was to determine the efficacy and safety, and to introduce the simple fusion technique. We usually used this technique for the patients who had been planned single level fusion without definite preoperative instability. Preoperative diagnosis were isthmic spondylolisthesis in one, spinal stenosis in three and laterally herniated lumbar discs in four in which postoperative instability was expected without performing fusion. A single-level fusion was perfomed in all patients. Fusion levels were L2-3 in two, L3-4 in one, L4-5 in four and L5-Sl in one. The average follow-up period was 20 months, ranging from 12 to 36 months. Overall clinical satisfaction including excellent and good result was obtained in all cases. The fusion rate was evaluated radiographically and all were solidly fused. The time to fusion ranged from 3 to 10 months at an average of 5.4 months. There were no significant complications including nerve root injury, and screw loosening or breakage. Although this study was retrospective and the number of cases were small, translaminar facet screw fixation for degenerative lumbar disease is simple and readily available, and provides sufficient rigid stabilization.

The frequent occurrence of hematuria in children necessitates diagnostic evaluation. Hematuria may occur with either renal or lower urinary tract disease. Clarification of the etiology of hematuria, whether microscopic or gross, is facilited by localizing the site of bleeding to the kidney (glomerular) or the lower urinary tract (non-glomerular). The mean cellular volume (MCV) of urinary red blood cells (RBCs) of pediatric patients with glomerular (group I; n=77) and non-glomerular (group II; n=34) hematuria was determined using Coulter Counter Model S plus IV. We found that re blood cells of glomerular origin had a smaller volume than non-glomerular cells(73.79 9.75 m3 vs 83.55 3.77 m3, p<0.001). If an urinary MCV equal to 80.56 m3 was taken as the cut-off value between glomerular and non-glomerular hematuria, a correct assessment of the site of bleeding was made in 89 (80%) of the 111 patients studied (sensitivity 76%, specificity 88%). The ratio of the urinary erythrocyte MCV to that in blood(Umcv/Bmcv) was compared with the diagnosis. If an Umcv/Bmcv ratio equal to 0.95 was taken as the cut-off value between glomerular and non-glomerular hematuria, a correct assessment of the site of bleeding was made in 93 (83%) of the 111 patients studied (sensitivity 79.6%, specificity 94%). Coulter counter analysis of urine provides a simple noninvasive and objective aid to the diagnosis of hematurai. This test, when used early in the management of pediatric patients with hematuria, may help to avoid invasive investigations.

Hip pain is a common but nonspecific symptom that has many etiologies. Due to the complex anatomy of the hip and pelvis, locating the exact origin of pain may be difficult. Soft tissue diseases around the hip are relatively rare and their clinical symptoms are often nonspecific. For such patients, it is necessary to understand various hip diseases, and do proper history taking and examination to correctly diagnose and treat soft tissue diseases of the hip. Advances in imaging studies such as MRI and ultrasonography can provide accurate information on soft tissues. This article reviews the soft tissue diseases of the hip that are experienced by clinics. It may be helpful in the differential diagnosis of hip pain arising from soft tissue structures and in the treatment of such diseases.

In our series with old electrical burn around the the wrist, there are several characteristics: for example, bad scarring in palm and volar aspect of wrist and distal forearm, large multiple defects of the flexor tendons, low median and ulnar nerve palsy, and occasionally insufficient blood supply. Between 1992 and 1995, we treated 8 cases of 7 patients with staged reconstruction. 4 patients with bilateral involvements had below-elbow amputee of contralateral upper extremity. The common approachs in each were soft tissue coverage, staged tendon reconstructiuon, and opponensplasty. The length of time between the injury and tendon reconstruction was 9 months on an average. Soft tissue coverage consisted of: 1. free tissue transfer (n=3), 2. abdominal (n=3) or groin (n=2). Total numbers of flexor tendon reconstruction were 26. Among them, staged reconstruction using silicone prosthesis were done in 18 tendons and primary tendon graft following tenolysis were done in 8 tendons. The time between first and second stage tendon reconstruction was 4.13 months. In all cases, opponen-splasty using extensor indicis proprius (n=4), extensor pollicis longus (n=2), and extensor digiti mini- mi (n=l), were performed. Good functional improvement of the hand were obtained in all cases. Patient s satisfaction were much better than the degree of functional improvement of the hand.

Incidence of non-contiguous multiple spine fracture was increased from 3.2%~4.5% at 1960th and 70th to 5.7% ~23.8% at 80th and 90th. But there is no reports in Korea which has high incidence of traffic and industrial accidents. In 345 consecutive patients with acute spine fracture, we found that 43 patients (12.5%) had multiple non-contiguous spine fractures. At the 43 patients studies 37 (87.4%) sustained fractures at 2 levels while 6 had more than 3 levels of injury, 26 were injured by fall from heights, 27 (62.8%) had 2.33 associated injuries on an average, and 12 (27.9%) had a neurologic deficit. There are five patterns account for 26 (50%) of the total number of patients. In 19 patients (44.2%), there was a mean 29.3 days delay (from 3 to 233 days) in diagnosis of the minor lesions. In 19 delay diagnosed minor lesions, it confirmed by bone scan in 12 patinets(63.6%). Two patients died within 24 hours after accident, and 41 patients (41 major and 50 minor fractures) were treated in our hospital. Among them, 21 (51.2%) needed modification of treatment by the presence of non-con- tiguous multiple spine fractures. According to above findings, the physician must be aware of the possible noncontiguous multiple spine fractures when examine and treat the patients with spine fracture.

The torsion of appendix testis is the second most common disease of the acute scrotal diseases in frequency. Despite recent development of diagnostic equipments, its differential diagnosis is often difficult and its treatment is controversial. We reviewed retrospectively 19 cases who were diagnosed to have torsion of appendix testis during recent 6 years. The mean age was 11.3 years. Five cases who had blue dot sign and tender mass on upper pole of testis, and one of 9 who had been examined with scrotal ultrasonography were diagnosed to have torsion of appendix testis, but other clinical finding and laboratory findings were not contributable to its diagnosis. Nine of 14 cases who were diagnosed by surgical exploration were consistent with the preoperative impression. Mean duration of scrotal pain were 1.3 days in surgical treatment group and were 3.6 days in conservative treatment group. The pathognomonic sign of torsion of appendix testis was seen only in a few cases. The diagnostic accuracy of torsion of appendix testis before exploration was low. The scrotal pain was relieved relatively more rapidly in surgical treatment group. So, we think that surgery was more desirable in diagnosis and treatment of torsion of appendix testis.

Vascularized fibular graft is one of the treatment option for avascular necrosis of femoral head (ANFH) and has been known as providing a strut mechanical support and new vascular bed. It is very important to evaluate a healing process in femoral head after vascularization procedure. But a plain radiographic finding has a problem to assess pathological changes of ANFH treated with vascularized fibular graft. Authors analyzed chronogical changes of Tc-99m-HDP bone scan in 31 cases of ANFH treated with vascularized fibular graft from April, 1991 to May, 1994 and following results were obtained. l. Until 2 months after surgery, no change in size of cold defect area and no significant change in extent of RI uptake in reactive zone were noted. 2. During 2 months and 6 months after surgery, slight decrease in size of cold defect area and minimal changes in extent of RI uptake in reactive zone were observed. 3. During 6 months and 12 months after surgery, size of cold defect area decreased to 1/2 and changes in extent and degree of RI uptake in reactive zone were observed. 4. During 1 year and 2 years after surgery, size of cold defect area were minimal and sometimes faded away. RI uptake with decreased density in reactive zone broadened and moved to subchondral area. 5. After 2 years after surgery, cold area faded away and small increased RI uptake were observed in same site. In conclusion, Tc-99m-HDP bone scan which is economic and easily applicable in a patient is very useful for follow up study in ANFH treated with vascularized fibular graft.
