Sixteen cases under the age of 19 were underwent surgical treatment for hernlated lumbar intervertebral disc over 10 years of period in the Department of Orthopaedic Surgery,Catholic Medical College. The results were obtained as follows: 1. The incidence was 5.2% of all herniated lumbar intervertebral disc patients who treated surgically, but no sexual predilection. 2. Nine cases (56.3%) had a definite previous history of injuries. 3. Average intervals between the onset of clinical symptoms and the operation were 9.2 months. 4. Neurologic deficits are less severe and frequent (8 cases, 50%) but the clinical symptoms do not differ from than that of the adult. 5. 7 cases (43.8%) revealed definite reptured lumbar intervertebral discs and 5 cases (31.3%) are diffuse buldging of annular fibers in operative findings. 6. According to histopathological study, 8 cases show degenerative fibrocartilagenous changes in surgical specimen. 7. The radiological abnormalities of lumbar spine are less common than that of the adult. 8. Excellent or good results were found in 12 cases (75%) but two cases required a further surgical procedure. 9. In generally, hernlated Iumbar intervertebral disc in teenagers show better results and more rapid recovery of clinical symptoms by surgical treatment, and less residual symptoms than that of the adult.

423 cases were underwent surgical treatment for herniated lumbar intervertebral disc during 12 years, and for these cases clinical analysis was done. The result were obtained as follows: 1. Among 423 surgically treated patients 20 are teenagers and male to female ratio was 309 (73.0%) to 114 (27.0%). 184 cases (43.2%) had a definite trauma histories, the types of injuries were lifting weight, direct trauma and slip down in order of frequency. 2. The teenagers had more severe tension sign and stiff back, while neurological dificits were less common in teenagers (45%) than the one in adult(55.2%). Average interval between the onset of clinical symptoms and time of operation were 3.4 months. 3. The definite discal rupture was found in 292 cases (69.0%) and the annular discal bulging were faund in 89 cases (21.0%). The most common site of lesions were between L 4-5 vertebrae (76.8%) and the next between L5-51 and L3-4 vertebrae. 4. The majority of surgically removed discs showed degenerative changes histopathologically. 5. Intervertebral discal space changes on X-ray after surgery were the narrowing of space, eburnation of end plate, spur formation and segmental instability, etc. 6. In this series of disc surgery were persistent backache, tingling and/or numbness in the leg, stiffback and limited S.L.R., etc., and the post-operative complications were subcutaneous hematoma, soft tissue infection, drop foot and diskitis, etc..

Two collateral ligaments, accessory collateral ligaments, volar plate which prevent hyperextension of digital joints, fibrous flexor sheath which attached to volar plate, intrinsic and extrinsic muscles were contribute to the stability of the digital joints. Among them, two collateral ligaments were most important as a static stabilizer. Especially, the instability of fingers due to the rupture of ulnar collateral ligament of metacarpophalangeal joint of thumb and radial collateral ligament of index will attenuate the pinch power and maybe a cause of chronic painful limited finger motions. So, they should be repaired if ruptured completely. During the period of May 1980 to Oct. 1985, 17 cases of ruptured collateral ligaments 5 cases in thumb, 12 cases in fingers were treated surgically and followed up for average 8 weeks. The results were that normal range of digital joint motion were obtained in 14 cases and instabilities were disappeared in 16 cases and pain free in 12 cases. Therefore, careful clinical evaluation to detact therupture of collateral ligament of dig.ital joint after hand injury and then appropriate management could restore the best function of hand.

The potential for nerve regeneration and recovery of its function exists in the presence of a suitable pathway for regenerating axon and endoneurial tube can serve as nerve conduit for regenerating axon in fresh nerve graft. But value of degenerated nerve as donor nerve has not been established till now. This experiment assessed the chronologic influence of fresh and degenerated nerve graft on axonal growth for 10mm gap of sciatic nerve in rabbit and how long degenerated nerve was ahle to serve as a nerve conduit microscopically. Electromicroscopically, the regenerating axons which were ohserved in the degenerated nerve graft had more abundant unmyelinated fibers and revealed abundant collagen fibers in the endoneurium. And these regenerating axons became gradually surrounded with newly developed basal lamina and decreased the collagen fibers at l2 week of degenerated nerve graft. Histologically, myelinated axons which were observed in central area of the degenerated nerve graft at 8 week of degenerated nerve graft were relatively thinner, but a definite structural difference of regenerating axons was not found except reduction of number compared with those of tresh nerve graft. The numher of myelinated axons was 6,072+/-l42 in normal sciatic nerve, 4,479+/- 157 in fresh nerve graft group, and 2,968+/-168 in the degenerated nerve graft group. Difference of the number of myelinated axons between fresh and degenerated nerve graft group was significant stati stically(P<0.05). These results showed that the ability of a degenerated nerve graft as a passage for the regenerating axons and it can be employed as one of the favorable nerve conduits.
