Cysts of the meniscus are rare lesion of the knee. They may present as a local tumor or mimic signs of an internal derangement of the knee. So it is difficult to diagnose and apt to overlook in physical examination. Also they almost always have combined pathology of the involved meniscus, such as, meniscal tear or discoid meniscus. The pathologic basis of the meniscal cyst is controversial, but rece 2. Most of the patients had tear of the involved meniscus, but the patients with discoid meniscus did not have gross tears or previous trauma history. nt works suggest the etiology is infiltration of joint fluid through micro and macro tears in the meniscus. In the past, complete excision of the meniscus as well as cyst was thought to be the treatment of choice to prevent recurrences. But nowadays, the trend is changed as preserving the involved meniscus, when no tear of the meniscus is found to prevent enevitable degenerative changes after total meniscectomy. We experienced 6 cases of meniscal cyst during recent 2 years and obtained following results. 1. Precise joint line evaluation is much more important in the diagnosis of the meniscal cyst before making special study. 2. Most of the patients had tears of the involved meniscus, but the patients with discoid meniscus did not have gross tears or previous trauma history. 3. When the cyst is located anteriorly in the joint line, it is prominent in flexed position of the knee; and when located posteriorly, prominent in extended position of the knee. 4. Excision of the cyst and reattachment of the meniscus were thought to be good method when the cyst was located in the parameinscal area without gross tear of the involved meniscus.

Opposition of the thumb is necessary for pinch-one of the three most important functions of the hand. Frequently, opposition is either partially or totally lost in poliomyelitis or median nerve palsy. Several types of operations have been devised for restoration of opposition, and in 1973, Burkhalter et al. announced extensor indicis proprius opponensplasty: the tendon of extensor indicis proprius is brought out in the area of the pisiform and then passed against subcutaneously across the palm to the thumb, being attached to the abductor pollicis brevis and extensor pollicis longus tendon. It is useful in the case of loss of opposition without available finger flexor or wrist motors. Of nine patients who underwent operation-one with Riordan and eight with Burkhalter type of opponensplasty-at National Medical Center, seven had excellent results: one had a fair, and another one had a poor result. Six patients were with low combined median and ulnar nerve injury: one with high combined median and ulnar nerve injury: one with brachial plexus injury: and one with myotmesis of the thenar muscles. From the results, we conclude that Burkhalter type of opponensplasty makes satisfactory result for the hand without opposition movement; it is indicated in high median nerve injury and any combined median and ulnar nerve injury6; early restoration of opposition to the thumb in median nerve injury and in those limbs with multiple tissue trauma adds immeasurably to the over-all early rehabilitative effort.

Ganglia are the most common soft tissue tumors of the hand. Ganglia found on the dorsum of the wrist usually arise from the scapholunate ligament and are usually located between the extensor digitorum communis tendon of the index finger and extensor pollicis longus tendon. Intratendinous ganglion is a very rare lesion of unknown etiology and natural history that originates within the tendon. A patient is described who presented with a painful mass on the dorsolateral aspect of the wrist due to an intratendinous ganglion of the extensor pollicis longus tendon. Treatment consisted of excision of the extensor pollicis longus tendon with ganglion followed by mini free tendon graft using palmaris longus tendon.

Injuries of the cervical spine from C3 down to C7 are complex and potentially devastating injuries. The treatment of this condition is complicated and controversial. However, there is an increasing tendency to stabilize unstsble cervical spine injuries surgically with the benefit of good stability of the spine, easy nursing care, early mobilization and rehabilotation. We analysed clinically the 26 patients with unstable lower cervical spine injuries st the department of orthopaedics, National Medical Center from Jan. 1979 to Dec. 1988. The results obtained were as follows:1. The prevalent age distribution was between 20 and 50 years of age(71%), and the ratio between male and female was 6: l. 2. The most common cause of the injury was traffic accident(42%), and the most frequent mechanism of injury was distractive-flexion type(42%). 3. In the overall clinical evaluation, 73% of the patients were judged to have had excellent and good results, and the range of the motion was more limited in the patient who underwent posterior fusion due to wide level of fusion. 4. The patients with distractive-flexion injuries with minimal neurologic deficit were at risk of late instability following conservative treatment, and therefore open reduction and posterior fusion may be advisable. 5. The patients who were given posterior fusion were noted to have a few significant late changes, but the patient with anterior fusion carried a high incidence of progressive kyphotic deformity and persisting, pain. 6. When anterior fusion is used in the patient with posterior instability for the purpose of cord decompression, anterior cervical plate is valuable than the fusion with graft only in view of preventing progressive kyphotic deformity.

Radiographic measurement of cervical spine is very important in cervical spine injury especially those without fracture. Authors measured the retropharyngeal space, retrotracheal space, lordortic curve and sagittal diameter of cervical spinal canal in 148 cases of normal adult male. The results are as follows: 1 . In normal Korean adult male maximum retropharyngeal space is 7mm in C, level and Smm in Cs level. Maximum retrotracheal space is 16mm in C, level. 3. Loss of normal lordotic curve is shown in 21 cases(14.2%), 4. Average sagittal diameter of C, level is 21.27mm-it's the largest of all the cervical spinal cana1s, and that of C, level is 16.15mm-it's the smallest.

BACKGROUND AND OBJECTIVES: The myogenic response was originally described as a contraction of a blood vessel that occurred following an increase in intravascular distending pressure. Conversely, a reduction in intravascular pressure produces myogenic vascular relaxation. Recent attention has focused on the potential role of this myogenic mechanism in the control of tone in the resistance vasculature, and in particular on how this mechanism may contribute to the increased vascular resistance seen in hypertension. Therefore, in the present study, we investigated the role of myogenic tone in the generation and/or maintenance of hypertension. MATERICAL AND METHODS: Myogenic tone was developed by stretching of the basilar arteries of WKY (istar Kyoto rat) and SHR (spontaneously hypertensive rats). Contractile responses, PKC (protein kinase C) immunoblots and translocation of PKC and RhoA were measured. In the presence of extracellular Ca2+ the stretching of the resting vessel evoked a myogenic contraction in the basilar arteries of SHR and WKY. Myogenic tone was significantly greater in SHR than in WKY. However, in the absence of extracellular Ca2+, stretching evoked a myogenic contraction in SHR, but not in WKY. The stretch-induced myogenic tone was inhibited by nifedipine. The effect of nifedipine was similar in both SHR and WKY rats. H-7, calphostin C and Y-27632, also inhibited stretch-induced myogenic tone in both SHR and WKY. The inhibitory effects of these drugs were greater in SHR than in WKY. Immunoblotting showed rho A and PKC alpha were translocated from the cytosol to the cell membrane with stretching in both SHR and WKY. PKC beta, however, was translocated to the cell membrane with stretching in SHR, but not in WKY. CONCLUSION: These results suggest that stretch-induced myogenic tone is significantly greater in SHR than in WKY. Furthermore, the increase in amount and/or activity of PKC beta and ROK (rhoA-associated kinase) may be a key mechanism accounting for the enhanced myogenic tone in SHR.

An isolated aneurysm of the iliac artery is a very rare disease that can occur as the result of atherosclerotic degeneration, mycosis, trauma, medial necrosis, fibrodysplasia, or Marfan syndrome. This abnormality is often asymptomatic, and it has a potential risk of rupture. Since patients with chronic renal failure on hemodialysis have many comorbid conditions, the risk of rupture is increased. Here, we report the case of an isolated common iliac artery aneurysm that was caused by atherosclerosis in a patient on hemodialysis, and we review the relevant literature.
