The fenrou zhijian is defined as potential gap between different layers in the three-dimensional network structure formed by the twelve meridian tendons. Various pathological changes of the meridian tendons lead to the adhesion and closure of fenrou zhijian, causing abnormal mechanical conduction of the meridian tendon system, which in turn leads to painful bi syndrome of meridian tendons. As such, restarting the fenrou zhijian is the key to acupuncture treatment for painful bi syndrome of meridian tendons. Under the guidance of musculoskeletal ultrasound, the level and the angle of needle insertion of acupuncture at fenrou zhijian could be accurately controlled, the efficacy of acupuncture is improved.

4.The Ultrasonographic Features of Periarticular Diseases.
Korean Journal of Medicine 2015;89(6):620-631
Ultrasonography (US) is a cost effective diagnostic imaging tool suitable for routine clinical use. High frequency US is a well-established method for both the diagnosis and monitoring of inflammatory arthritis, capable of detecting a wide range of joint pathologies, including effusion, synovitis, and extra-articular abnormalities. However, to ensure an accurate diagnosis, it is also important to consider periarticular disorders that could clinically mimic joint pathology. Such a diagnosis requires special attention to be paid to the periarticular structures, include the tendon, ligament, muscle, and bursa. Due to the close proximity of these structures to potentially affected joints, periarticular inflammation is often clinically misdiagnosed as articular in origin. In these cases, the processes driving pathology are the result of localized inflammation that is secondary to inflammatory arthritis, such as excessive friction or direct trauma. Therefore, when using US to diagnose inflammatory arthritis, it is important to understand the causative pathology of the periarticular disorders, as well as their clinical presentation.

5.Variations and Morphometry of the Carpal Tunnel and Its Related Structures.
Journal of the Korean Academy of Rehabilitation Medicine 1999;23(2):210-223
OBJECTIVE: The purpose of this study was to find out diagnostic clue for the carpal tunnel syndrome. So we investigated the postional relationships between the structures, the degree of entrance of the muscle bellies in the carpal tunnel, the location of flexor retinaculum (FR) and the cross sectional area to the tunnel of the tendons, the median nerve and the soft tissues occupied with the wrist. METHOD: Seventy-seven wrists of Korean adults's cadavers were dissected. Fifty-three wrists were examined by posteroanterior view of X-ray. The area of each structure was measured by image analyzer (Optimas Co. WA). The upper and lower borders the FR were confirmed at the sagittal plane after sagittal section. RESULTS: Frequency of the bellies of FDS, FDP and lumbricalis observed in each finger, the length of these bellies entering into the carpal tunnel were obtained. The cases that the third and fourth FDS were located side by side, the second FDS tendon under the third FDS tendon and the fifth tendon under the fourth FDS tendon were most common. The cases that the median nerve was bordered on the third FDS and the second FDS deep inside of the median nerve were most common. Mean length of the FR was 32.1 mm. The cases that the location of the upper margin of the FR was 10 mm and 15 mm from the end of radius were most common (44%). The cases that the margin of FR was 5 mm and 10 mm from the base of the 3rd metacarpal bone were most common (52%). The cross sectional area ratios to the carpal tunnel of the tendon, median nerve and connective tissues were 30%, 4%, 66% at the level of the pisiform bone, 36%, 4%, 60% at the level of the hook of hamate and 28%, 3%, 67% at the level of the lower margin of the FR, respectively. CONCLUSION: These results could help to understand the etiology of the carpal tunnel syndrome and would be a helpful information to the diagnostic imaging of the carpal tunnel.

BACKGROUNDConventional ultrasonography or magnetic resonance (MR) imaging is commonly performed to obtain information about the severity of the disease, location of the injury, and differential diagnosis. The aim of this research was to investigate the diagnostic confidence of sonoelastography as an adjunct to greyscale ultrasonography in lateral elbow tendinopathy.
METHODSA single experienced physiatrist performed greyscale ultrasonography and sonoelastography in 28 patients (9 men, 19 women; mean age, 48.5 years; age range, 36-67 years) with unilateral symptoms of lateral elbow tendinopathy; the asymptomatic elbows were used as controls. Greyscale images were described as normal, tendinosis, partial-thickness tear, and full-thickness tear. Sonoelastographic images of the common extensor tendon were analyzed qualitatively (scoring of the elastic spectrum) and quantitatively (based on a color histogram).
RESULTSBoth the imaging methods had high sensitivity, specificity, and accuracy for diagnosing lateral elbow tendinopathy. Considering the clinical diagnosis of lateral elbow tendinopathy, sonoelastography showed significantly higher diagnostic accuracy (96.4%) than ultrasonography (89.5%, P < 0.01). Quantitative analysis showed objective interpretation of the sonoelastographic images that revealed greater intensity of green and blue pixels in symptomatic elbows (P < 0.01).
CONCLUSIONSonoelastography increases diagnostic confidence in tennis elbow pathology over greyscale ultrasonography alone and may be an additional powerful diagnostic tool in cases of lateral elbow tendinopathy with inconclusive greyscale ultrasonographic findings.

The bony naso-orbital-ethmoid (NOE) complex is a 3-dimensional delicate anatomic structure. Damages to this region may result in severe facial dysfunction and malformation. The management and optimal surgical treatment strategies of NOE fractures remain controversial. For a patient with NOE trauma, doctors should perform comprehensive clinical examination and radiographic analysis to assess the type and extent of fracture. The results of assessment will assist doctors to make a patientspecific program for the sake of reducing post-operation complications and restoring normal appearance and function as much as possible. This review focuses on the advancement of management of NOE fractures including symptoms, classifications, diagnosis, approaches, treatment and new techniques in this field.

8.Relationship between tunnel widening and different rehabilitation procedures after anterior cruciate ligament reconstruction with quadrupled hamstring tendons.
Chinese Medical Journal 2005;118(4):320-326
BACKGROUNDIt has been demonstrated that bone tunnel widening could appear after knee anterior cruciate ligament (ACL) reconstruction, especially for those patients whose ruptured ACL were reconstructed with semitendinosus and gracilis tendons. Many factors can influence the extent of tunnel widening. Few studies have investigated the relationship between bone tunnel widening and rehabilitation procedures. This research was carried out to find the rehabilitation procedures' influence on the tibial bone tunnel widening after ACL reconstruction.
METHODSSixty-five cases, whose ACL reconstructions were done using quadrupled semitendinosus and gracilis tendons, were divided into two groups. Group A had 33 cases, 19 men, 14 women, averaged (31.2 +/- 12.4) years old, only ACL reconstruction was done using Paessler's technique, and aggressive rehabilitation procedure was used for function recovery post operation. Group B had 32 cases, 20 men, 12 women, averaged (30.3 +/- 10.3) years old. Except for ACL reconstruction, every patient in group B accepted meniscus repair using re-fixation methods or cartilage repair using microfracture technique, conservative rehabilitation procedure was used post operation. Six months post operation, standard posterior-anterior radiographic plates were taken for each case, CorelDRAW 8.0 software was used to digitize all X-ray plates and measure the upper, middle and lower parts of the tibial tunnel. Magnification effect of X-ray plates was taken out after measurement.
RESULTSSix months after ACL reconstruction the tibial tunnel widening of the upper, middle and lower parts on both the posterior-anterior and lateral X-ray plates in Group A with aggressive rehabilitation procedure was much more serious than in Group B with conservative rehabilitation. KT-1000 knee stability measurement and clinical manifestation showed no difference between the two groups.
CONCLUSIONSRehabilitation procedure after ACL reconstruction is one of the reasons for tunnel widening. It not only can directly influence the function recovery of ACL reconstructed knee, but also perhaps indirectly influence the function recovery and long-term clinical result of the operated knee by influencing the tunnel widening.

10.Acquired Flat Foot due to Rupture of Posterior Tibial Tendon: Two case reports.
Journal of the Korean Academy of Rehabilitation Medicine 1997;21(5):1024-1029
The posterior tibial muscle is considered a plantar flexor as well as an invertor of the foot, which acts as a key muscle to the medial longitudinal arch by locking the talar joints in normal gait. Rupture of the posterior tibial tendon can cause a valgus deformity of the hindfoot and an abduction deformity of the forefoot which produces a typical flat foot and a talar dislocation in severe cases. The tendon of posterior tibial muscle can be ruptured spontaneously after the age of 40 from chronic stress at the ankle joint, or by sports injury and trauma. Severe foot deformity which can be prevented by early diagnosis and appropriate treatment often occurs from misdiagnosis as a chronic ankle sprain or a congenital flat foot. We report two cases of foot deformities caused by spontaneous and traumatic rupture of posterior tibial tendons with their clinical manifestations and MRI findings.
