The spondylolysis is a defective ossification in the pars interarticularis of the neural arches without displacement of the vertebral body. The authors analysed 810 lumbar spines of adult Korean laborers on the basis examined to determine the anatomic characteristics of spondylolysis. The following results were obtained. 1. The overall incidence in laborer was 6.8%. 2. The most frequent site of the involvement was the fifth lumbar vertebra. of radiologic study and 3. Spina bifida in spodylolysis was approximately 1.7 times as frequent as is normally expected. 4. Lumbarization in spondylolysis was approximately 5.8 times as frequent as is normally expected. 5. Sacralization was not found in 55 cases of spondylolysis.

The term juxta-facet cyst has been used to characterize two types of periarticular cystic alterations, synovial and ganglion, that can occur in the paraspinal region. Synovial cysts arise from synovial outpouchings through the weakened or destroyed capsular tissue.Ganglion cysts are commonly found about the wrist and hand.But theoretically they can occur at any site in the body where periarticular connective tissue is present. In spinal canal these cysts may cause pressure on adjacent nerve root to produce a variety of neurological symptoms. The clinical features indicated an acute onset of symptoms favoring a diagnosis of disc herniation, so differential diagnosis is important.We have experienced two cases of the intraspinal extradural cysts connected to posterior longitudinal ligament by a sheath, causing nerve root compression. those were managed with excision of the cyst, and no recurrence has been identified during follow up evaluation.

Chronic cavities of the dorsum of the foot often have bare bone and are unsuitable for free skin grafting. Local Flaps are often impossible because of surrounding scar tissue and dead space. A simple method is presented; it consists of the excision of the lesion, filling the cavity by a two staged random-pattern de-epithelialised turn over flap, and skin graft.

The aim of this study was to compare widely used quantitative sensory tests to evaluate the diabetic neuropathy(DN). We tested plantar sensation of 40 patients with diabetes mellitus(Group I: 20 with neuropathic symtom, Group II: 20 without symptom) using Semmes-Weinstein monofilament(touch sensation), Biothesiometer(vibration sensation) and EMG. This result was also compared with that of the control group. Eighty percent of Group I and thirty percent of Group II had abnormal EMG findings. Group I had decreased vibration and touch sensation. Comparison of vibration perception threshold(Biothesiometer) with touch pressure sensation(Semmes-Weinstein monofilament) showed that the test with Biothesiometer was relatively accurate, however it was complicated, time consuming and that the test with monofilament was simple and easily performed in the field even though it was relatively crude. 5.07 monofilament could be very effective in the eearly detection of diabetic neumpathy. In conclusion, we recommend 5.07 monofilament as a screening method of diabetic neuropathy and biothesiometer as its follow-up method.

The standard treatment of adult femoral shaft fractures is the closed intramedullary nailing using a fracture table, but in polytraumatized patients, this method may be difficult due to concomitant adjacent injury. So, we report on the technique of closed intramedullary nailing without a fracture table for adult femoral shaft fracture using "joystick" technique on radiolucent table in supine position. Among 15 cases, two were open fractures, three were proximal 1/3, seven were middle 1/3, two were distal 1/3, and theree were segmental fractures. According to the Winquist Hansen classification, five type I, four type II, three type III, three were type IV. The eleven patients out of the fifteen were operated within 48 hours. The average operation time was 105 minutes, and the amount of bleeding was below 300cc. Forty-seven percent was anatomically reduced, forty percent had below five degree of angular deformity or below five milimeter of shortening, thirteen percent had above five degree of angular deformity of above five milimeter of shortening. The closed intramedullary nailing of femoral shaft fractures without fracture table using radiolucent table and "joy stick" technique is an effective and safe method in multiple injuries. And it reduced the operation time by reducing the preoperation time including preparing of a fracture table.

graft as a successful procedure that provides functional stabiIity. Complications reported include arthro5brosis, patellofemoral joint pain, patellar tendinitis, patellar tendon rupture, recurrent laxity, posterolateral instabi5ty, medial subluxation of the patella, chronic knee pain and painful neuroma. Among them, anterior knee pain was the rnost frequent eomplication. Authors performed arthroscopy assisted one tunnel technique for reconsction of the ACL using autogenous Bone Patellar tendon-Rone (BPTB) in 87 patients. Patients were divid@d into two groups based on the harvested side (knee) of the BPTB. Group 1 consisted of 45 cases of ipsilateral side and group 2 consisted of 42 cases of contralsteral side in harvesting the BPTB. The patients were foll4wed up for at least 12 months to determine whether using the BPTB harvested from the contralateral knee wguld reduce the anterior knee pain at the ACL reconstructed knee. Althaugh there were no statistically signifiqant differences between group 1 and 2 with regard to anterior knee pain, the prevalence of the anterior knee pain was less frequent in group 2 than group 1. This study showed that using the contralateral side harvested autogenous patellar tendon would be a possible protector for anterior knee pain and assists for early rehabilitation.

Chondrocytes isolated from the articular cartilage of rabbit knee joint were cultured in vitro within fibrin glue carrier for 2 weeks. Histochemical and electromicroscopical approaches were used to study chondrocytes behavior and phenotypic expression. In vitro study, chondrocyte assumed a rounded morphology, accumulated metachromatic matrix and took on the cytological characteristics of in vivo cartilage cells. Allogenic cultured chondrocyte in fibrin glue was transplanted into osteochondral defect in rabbit joint. The contralateral knee joint served as a control in which the defect was left empty. This in vivo study was performed for the investigation of the chondrogenic potential of cultured chondrocytes embedded in fibrin glue. Grafted defects was filled with cartilage in gross finding, repaired tissue consisted of differentiated chondrocytes and matrix resumed that of hyaline cartilage. At sixteen week after transplantation, subchondral region was partially transformed into bone without loss of overlying articular cartilage, but in control group, defect did not heal successfully. Repaired articular cartilage was thicker than host cartilage and tide mark was not shown up to 24 weeks. Some of repaired tissue was degraded partially. These results suggest that fibrin glue provides suitable environment for differentiation of chondrocyte and allograft of cultured chondrocyte in fibrin glue transplanted into large osteochondral defect improves cartilage repair.
