Followed by a paper on the Pig and Bone orthopedic prosthetic, this experiment using Phantom and Bone MRI imaging I, II of orthopedic prosthetic metal effect combines magnetic resonance imaging on metal signal-to-noise ratio(Signal to noise : SNR) and CNR(Contrast to noise: CNR), fat signal suppression(Fat-suppression) images was compared. Specimen trees to measure the reliability of the experimental reproducibility tests and statistical analysis using the SPSS statistical package was applied program SPSS(IBM SPSS Statistice 19) by * P = 0.000 < significance level $({\alpha})$ = 0.01 as a significant there was a correlation(** P < 0.01). SNR and CNR results did not directly proportional to the Titanium, Stainless, Clip CNR and fat signal suppression of the order of images of blood specimens was found to be close to the image. The impact of orthopedic prosthetic metals on magnetic resonance imaging in the diagnostic value of Titanium is relatively high and are meant more.

연골육종은 조직학적 소견에 따라 grade I, II, III로 나누어지며 예후와도 깊은 관련이 있다. Grade II 및 III의 연골육종의 수술 시 광범위 절제를 주로 시행하나 grade I 연골육종의 경우에는 소파술과 광범위 절제술 사이에 이견이 많다. 저자들은 상완골의 근위부에 grade I, 원위부에 grade II의 연골육종이 발생한 경우에 grade I은 소파술을, grade II는 광범위 절제술을 시행한 경험을 하였기에 보고하는 바이다.

Although osteochondromas are common bone lesions, extraosseous osteochondromas are rare. The most common sites of involvement are the hand, knee, and foot. The authors experienced a case of soft tissue osteochondroma in the plantar aspect of the left foot. The patient complained of a palpable mass for 5 years. The mass grew slowly and had been asymptomatic until 5 months prior to admission when the patient developed slight pain on ambulation and numbness distal to the mid foot. Radiologic studies demonstrated well-circumscribed, lobulated, ossified mass in the plantar aspect of the mid foot. Histological examination confirmed a osteochondroma of soft tissue origin.

Purpose: Chronic subtalar instability is not common and similar to chronic ankle instability and the incidence and cause chronic subtalar instability are not well known. Recently we have experienced chronic subtalar instability without chronic ankle instability which was treated with modified Brostrom procedures. Materials and Methods: The patient is 46 year old man who has suffered from left ankle sprain for 30 years and recently aggravated more than twice a day. On subtalar stress view, 14 degree angulation of subtalar joint was noted and on anterior drawer view, 8 mm anterior displacement of left ankle was seen. Results: In operation, there was no anterior talofibular ligament abnormility but calcaneofibular ligament loosening was found. Ligament reconstruction was performed using modified Brostrom procedure. At 12 months after operation, the patient complains no pain and no limit of motion and no instability. Conclusion: We experienced chronic subtalar instability without ankle instability treated with modified Brostrom procedures. No instability was found after treatment without complication.

결절종은 수부나 손목 관절의 관절막 혹은 건초에서 흔히 발생하는 연부 조직 양성 종양으로 초음파상 경계가 명확한 저 에코성의 낭성 종괴로 보여 비교적 정확하게 진단할 수 있다. 저자들은 손목 관절의 수장부 요측에서 촉지되는 종괴에 대하여, 술전에 시행한 초음파 검사 상 고 에코성 소견을 보여서 고형성 종괴로 추정하였으나, 수술 소견 및 조직학적 검사에서 결절종으로 진단되었던 예를 경험하였기에 고 에코를 보이는 결절종에 대한 문헌 고찰과 함께 보고하고자 한다.

Purpose: Body mass index (BMI) is often used to predict surgical difficulty in patients receiving total knee arthroplasty (TKA); however, BMI neglects variation in the central versus peripheral distribution of adipose tissue. We sought to examine whether anthropometric factors, rather than BMI alone, may serve as a more effective indication of surgical difficulty in TKA. Materials and Methods: We prospectively enrolled 67 patients undergoing primary TKA. Correlation coefficients were used to evaluate the associations of tourniquet time, a surrogate of surgical difficulty, with BMI, pre- and intraoperative anthropometric measurements, and radiographic knee alignment. Similarly, Knee Injury and Osteoarthritis Outcome Score (KOOS) was compared to BMI. Results: Tourniquet time was significantly associated with preoperative inferior knee circumference (p=0.025) and ankle circumference (p=0.003) as well as the intraoperative depth of incision at the quadriceps (p=0.014). BMI was not significantly associated with tourniquet time or any of the radiographic parameters or KOOS scores. Conclusions: Inferior knee circumference, ankle circumference, and depth of incision at the quadriceps (measures of peripheral obesity) are likely better predictors of surgical difficulty than BMI. Further study of alternative surgical indicators should investigate patients that may be deterred from TKA for high BMI, despite relatively low peripheral obesity.

Rare cases of a congenital absence of the long head of the biceps tendon (LHBT) have been reported, and its incidence is unknown. In a literature review of the congenital absence of the LHBT, only 1 case was associated with posterior shoulder instability and severe posterior glenoid dysplasia. This paper reports the first case of a patient with a bilateral congenital absence of the LHBT with posterior shoulder instability without glenoid dysplasia or posterior glenoid tilt. The patient experienced a traffic accident while holding the gear stick with his right hand. After the accident, a posteroinferior labral tear with paralabral cysts was detected on the magnetic resonance images. The congenital absence of the LHBT was assumed to have affected the posterior instability that possibly increased the susceptibility to a subsequent traumatic posterior inferior labral tear. This case was identified as a posterior inferior tear caused by a traumatic 'gear stick injury'.

A 51-year-old male who is right-handed visited the outpatient for right fingers-drop. The patient's fingers, including thumb, were not extended on metacarpophalangeal joint. The active motion of the right wrist was available. The electromyography and nerve conduction velocity study were consistent with the posterior interosseous neuropathy. Further evaluation was done with the magnetic resonance imaging for finding the space-occupying lesion or any possible soft tissue lesion around the radial nerve pathway. On magnetic resonance imaging, the ganglion cyst, which was about 1.8 cm in diameter, was observed on the proximal part of the superficial layer of the supinator muscle (Arcade of Frohse). The surgical excision was done on the base of ganglion cyst at the base of stalk of cyst which looked to be connected with proximal radioulnar joint capsule. The palsy had completely resolved when the patient was observed on the outpatient department a month after the operation.

Gout occurs mainly in monoarthritis and is found in more than 50% of cases in hallux of the foot. In addition, symptoms sometimes begin in the hand, wrist, and elbow, but they are rarely observed in the spine. The patient was referred for tuberculous polyarthritis due to antituberculosis drug failure. Inflammatory findings were observed in the lumbar, elbow, wrist, hand and foot areas. Surgery was performed on the foot area and a pathology diagnosis revealed gouty arthritis. We report this case with a review of the relevant literature.
