Coracoclavicular ligament is main restraint to superior instability of the distal clavicle. Coracoacromial ligament, extensor tendon of toe, palmaris longus tendon, and Dacron tape have been used to reconstruct coracoclavicular ligament. We used semitedinosus tendon to reconstruct coracoclavicular ligament. The semitendinosus tendon was harvested as a usual fashion. After the distal clavicle and coracoid process were exposed, a hole of six millimeter diameter was made on the center of whole thickness of the distal clavicle. A malleolar screw was fixed from distal clavicle to coracoid process to maintain the reduced position of the acromioclavicular joint. The leading suture of tendon graft was passed through the hole of the distal clavicle and looped under the coracoid process. After leading portion of ten­don graft was looped over the clavicle, sutures were made between each end of the tendon graft with nonabsorbable suture materials.

This study was designed to investigate the effect of Bee Venom Acupuncture on Ligament Relaxation. The patient was treated with Bee Venom Acupuncture Therapy, Acupuncture and Microwave. Bee Venom Acupuncture Therapy was administered at fibroosseous junction of the relaxed ligament. We evaluated the patient through Visual Analogue Scale(VAS) and Range of Motion(ROM), tenderness. Atter treatment, the patients showed that clinical symptoms was disappeared, VAS changed from 10 to 1 and there was no limitation of ROM. According to the result, Bee Venom Acupuncture Therapy may have rapid effects on the Ligament Relaxation. But further studies are required to prove the effect of Bee Venom Acupuncture Therapy of Ligament Relaxation

Objectives : Primo vascular system is known to new circulatory system and suggested as a anatomical structure of meridian system. Primo-vessels are present throughout the whole body. The purpose of this study is to identify primo tissues taken from falciform ligament and to compare with organ surface primo tissue, blood vessel and lymph vessel. Methods : Male Sprague-Dawley rats (8weeks old, 250~320g) used for this study. The medial line of the abdomen was dissected and searched for primo tissues in falciform ligament and on the internal organs using stereomicroscope. We performed serial cross section and histological investigations. The tissues were stained with hematoxylin-eosin and Masson's trichrome. Results : 1. The primo tissues attached on the falciform ligament had white color and length of 5~8mm. 2. We could observe primo tissues are classified with ligament tissues. 3. Histologically, primo tissue on falciform ligament and organ surface primo tissue could be considered same tissue. Conclusions : In this study, we observed primo tissue discovered on the falciform ligament. And we also histologically compared such discovered primo tissue with organ surface primo tissue. Consequently, we could consider that two tissues have histological similarity and possibility of connection in one network system.

Purpose: Rupture of a collateral ligament of the metacarpophalangeal joint is rare except in the thumb. The injured digit became flexed and deviated toward ulna side by the hypothenar intrinsic musculature. Incomplete rupture of a collateral ligament of the metacarpophalangeal joint can be often managed by splinting the affected digit in flexion position, however, in the case of complete tears that distraction of the ends of the ruptured collateral ligament is too great to allow repositioning by splinting. Primary repair of the ruptured collateral ligament or reattachment to bone by a pull-out wire, or tendon graft technique appears to be adequate. Methods: We report a case of instability of fifth metacarpophalangeal joint due to complete rupture of radial collateral ligament. This 18-year-old male presented pain in his right outstretched hand after trauma. The diagnosis was obtained by physical examination and simple radiography. Because of persistent instability after the initial conservative treatment, open reduction and repair surgical treatment was required. Results: The fifth metacarpophalangeal joint became free of pain and stable under forced lateral deviation. Postoperative results showed good metacarpophalangeal joint function and stability during 8 months follow-up period. Conclusion: Because of the interposition of the sagittal band between the ruptured ends of radial collateral ligament such as Stener-like lesion of the thumb, surgical repair of metacarpophalangeal joint collateral ligament of the finger was justified in case of complete laxity in full flexion.

As the periodontal ligament cells show similar phenotype with osteoblasts, periodontal ligament cells are thought to play an important role in alveolar bone remodeling. According to recent studies, receptor activation of nuclear factor $^{\kappa}B$ ligand (RANKL) and osteoprotegerin (OPG) are expressed in periodontal ligament cells during tooth movement. Also periodontal ligament cells is known to play an important role in the progression of periodontal disease. This study was designed how the expression of RANKL and OPG in periodontal ligament cells was regulated by IL-1 ${\beta}in$ the concentration of $0.01{\sim}10$ ng/ml. The results are as follows; 1. Periodontal ligament cells which stimulated by 1L-1 ${\beta}$ increased soluble RANKL synthesis by dose-dependent pattern in the concentration of $0.01{\sim}10$ ng/ml. 2. 1L-1 ${\beta}$ induced mRANKL expression in dose-dependent manner in the concentration of $0.01{\sim}5$ ng/ml. 3. mOPG expression was not to be influenced by 1L-1 ${\beta}$. These results suggested that rat periodontal ligament cells could regulate osteoclastogenesis by stimulation of production of RANKL.

Purpose: The purpose of this study was to assess the prevalence and radiographic characteristics of the nuchal ligament ossification on lateral cephalometric radiographs in Koreans. Subjects and Method: I review and interpreted the lateral cephalometric radiographs from 4,558 patients (1,857 males and 2,701 females, age range from 2 to 79 years) who visited the Kyungpook National University Dental Hospital from January 1, 2008 to February 3, 2009. I grouped the shapes of nuchal ligament ossification as round, rod-like, and segmented shape. And localized the ossification as the involvement of anterior cervical vertebral body. The data were analyzed by using chi-squared test with two-tailed and at a 5% significance level. Results: Among those who showed the nuchal ligament ossification, he mean age of the 143 males was 51.1 and that of the 97 females was 48.0 years. It as not observed completely below teens, and was observed 1% in twenties, 6.1% in thirties, 18.6% in forties, and 26.3% over fifties. It was significantly prevalent in older age group (P<0.01) and in males than females among the same age group (P<0.05). The shapes of nuchal ligament ossification were as follows in order of frequency: rod-like (49.2%), round (30.4%), and segmented (20.4%). The highest involvement of ossification as found at the level of C5 (67.9%), C4 (29.2%), C6 (22.9%), C3 (3.3%), C7 (2.9%), C2 (0.8%), and C1 (0.4%). Conclusion: The nuchal ligament ossifications on lateral cephalometric radiographs were showed as round, rod-like, or segmented shape. The nuchal ligament ossification is often observed after the age of 40 and is observed more frequently in males than females. The highest shape of nuchal ligament ossification was rod-like shape and the highest involvement of cervical spine was C5.

Background: The purpose of this study was to investigate the usefulness of quadriceps exercise for improvement of knee extensor muscular function after cruciate ligament reconstruction. Methods: Participate in 18 of patients with cruciate ligament reconstruction, ACL & PCL reconstruction was 9 of patients, respectively. All subjects instructed that quadriceps exercise repeated daily, composed to QSE(quadriceps femoris setting exercise) and SLR(straight leg raises). Knee extensor muscular function was measured before and after quadriceps exercise. Initial test was measured before cruciate ligament reconstruction, and retest was measured 6month after cruciate ligament reconstruction. Results: Knee extensor muscular function significantly increased in both ACL and PCL reconstruction(P<0.05). Conclusion: The results of this study indicated that quadriceps exercise useful for improve knee extensor muscular function in patients with cruciate ligament reconstruction.

Ganglion cysts of the cruciate ligaments of the knee are rare and their pathogenesis is uncertain. A few cases of the cyst of the posterior cruciate ligament were reported in the literature. We have arthroscopically treated sucessfully the ganglion cysts of the posterior cruciate ligament through the anteromedial portal. We reported three cases of ganglion cyst of the posterior cruciate ligament with brief of literatures.
