Anterior glenohumeral instability with an irreparable subscapularis tear is a challenging problem for the orthopedic shoulder surgeon. Current techniques, including tendon transfers, yield inconsistent results with high rates of recurrent instability. Acellular dermal allografting has been used in young patients with massive superior rotator cuff tears with early success, but acellular dermal allografting is comparatively unstudied in anterior deficiency. We present two cases of anterior capsular reconstruction with an acellular dermal allograft in patients ages 66 and 58 years with irreparable subscapularis tendon tears. Follow-up for both patients exceeded 4 years, with forward flexion >140°, external rotation exceeding 60°, a Single Assessment Numeric Evaluation score >90 points, a visual analog scale score of 0 points, and an American Shoulder and Elbow Score of 98 points. In conclusion, acellular dermal allografting can be used to reconstruct the anterior capsule in patients with massive irreparable subscapularis tears, similar to its use in superior capsular reconstruction in patients with massive posterosuperior rotator cuff tears.

Rupture of the pectoralis major muscle typically occurs in the young, active male. Acute management of these injuries is recommended; however, what if the patient presents with a chronic tear of the pectoralis major? Physical exams and magnetic resonance imaging can help identify the injury and guide the physician with a plan for management. Nonoperative management is feasible, but is recommended for elderly, low-demand patients whose functional goals are minimal. Repair of chronic tears should be reserved for younger, healthier patients with high functional demands. Although operative management provides better functional outcomes, operative treatment of chronic pectoralis tears can be challenging. Tendon retraction, poor tendinous substance and quality of tissue, muscle atrophy, scar formation, and altered anatomy make direct repairs complicated, often necessitating auto- or allograft use. We review the various graft options and fixation methods that can be used when treating patients with chronic pectoralis major tears.

The growth and yield of Job's tears (Coix lacryma-jobi L.) under the flooded paddy and upland (dry paddy) field conditions were compared at three sowing dates and two planting densities. Job's tears grown under flooded paddy field was much shorter in plant height, but greater in number of tillers than those grown under upland. Photosynthesis rate of Job's tears grown under flooded paddy field was higher and the weight of dry roots heavier but the damages of pest and leaf blight disease smaller than those grown under upland. For the above mentioned reasons, the grain yield of Job's tears grown under flooded paddy field was higher by up to 85% than that grown under upland. There was no significant difference in grain yield between the planting densities. The earlier sowing brought about the less grain yield in upland field condition, while sowing plot on the 15th of May showed the highest grain yield in the flooded paddy field condition.

The effect of heat treatments on in vitro starch hydrolysis of proso millet, sorghum, Job's tears, and buckwheat by pancreatic ${\alpha}-amylase$ was investigated. Grain samples were tested raw, boiled in water, or steamed/roasted. Starch content of the grains varied from 59.5% in Job's tears to 65.5% in proso millet, and amylose content varied from 5.3% in Job's tears to 36.3% in buckwheat. The in vitro starch hydrolysis of raw and heat-treated grains continuously increased during 60 min of hydrolysis. The starch hydrolysis (%) of raw grains after 60 min incubation was in the order of buckwheat (5.7%), proso millet (33.0%), Job's tears (51.2%), and sorghum (57.6%). Grains treated with steaming/roasting appeared to have higher starch hydrolysis rates than those with boiling except proso millet. Hydrolysis rates of buckwheat with a high amylose content appeared to be lower, compared to proso millet, sorghum, and Job's tears containing low amylose contents.

Background: Patients with rotator cuff tears are usually afflicted with shoulder pain and disability. However, it is unclear which factors are related to shoulder pain in patients with rotator cuff tears. This study was therefore undertaken to determine the factors correlated with shoulder pain in patients with painful rotator cuff tears, but without any history of trauma. Methods: We evaluated a cohort of 745 patients with painful rotator cuff tears having no trauma history, and analyzed the relationship between pain and multiple factors including demographic data, tear characteristics, and passive range of motion. Pain was analyzed with a questionnaire concerning the visual analogue scale (VAS) for pain. Tear characteristics were determined by evaluating tear size, muscle atrophy, number of torn tendons, and presence of arthritis. Multivariate linear regression analysis and chi-squared test were applied to evaluate the relationship between the VAS for pain and variable factors. Results: Shoulder pain was associated with young age (p=0.01), male sex (p=0.01) and the presence of diabetes mellitus (p<0.001). Measurements of rotator cuff tear characteristics including tear size (p=0.53), muscle atrophy (p=0.16) and the number of torn tendons (p=0.34) did not correlate with shoulder pain. Symptom duration (p=0.60) and range of motion (p>0.05) also showed no correlation with VAS for pain. Conclusions: Young age, male sex and the presence of diabetes mellitus correlated positively with preoperative shoulder pain in patients with painful rotator cuff tears without a trauma history. Combined treatment of pain management and risk factor correction could be helpful to control preoperative shoulder pain.

Purpose : The purpose of this study was to investigate the incidence, location, type and treatment of meniscal injury associated with acute anterior cruciate ligament (ACL) tears Material and Methods: From Mar. 1997 to Feb. 2002, we reviewed 73 cases of acute ACL tear. There were 66 males and 7 females. The average age at the time of surgery was 33 year old (range, 16-62 years). The common causes of meniscal injury were sports injuries (45 cases) and traffic accidents (19 cases). In 45 sports injuries, thirty four cases were soccer injuries. All patients had undergone arthroscopic evaluation. We analyzed incidence, type, location, and treatment of meniscal injuries, especially those of soccer injuries. Results : Foully eight (57 sites) out of 73 had meniscal tears : Of these injuries, tears of lateral meniscus (26 cases, $54.2\%$) were more common than medial meniscus. Posterior horn of the meniscus was the most common location (52 cases, $91.2\%$) and radial tears were the most common type (15 cases, $26.3\%$). Thirty eight cases $(66.7\%)$ were treated by partial menisectomy. In soccer injuries, twenty eight (33 sites) out of 34 had meniscal tears. and tears of lateral meniscus (17 cases, $60.7\%$) were more common. Posterior horn of the meniscus was the most common location (30 cases, $90.9\%$) and radial tears were the most common type (9 cases, $27.3\%$). Twenty two cases $(66.7\%)$ were treated by partial menisectomy. Conclusions : Lateral meniscal tears in the setting of an acute ACL insufficiency are more common than medial meniscal tears. The findings in the this study would be helpful in clinical diagnosis and subsequent treatment decisions in patients with an acute ACL tears.

Purpose : The purpose of this study is to determine whether adding an angled oblique sagittal plane to the routine shoulder MRI improves the diagnostic performance in the evaluation of supraspinatus tendon tears with arthroscopic correlation. Materials and Methods: The study included 121 patients who had a shoulder MRI followed by arthroscopy. Two radiologists separately evaluated the supraspinatus tendon for tears on shoulder MRI either with or without the angled oblique sagittal images. Arthroscopy was used as the reference standard. The sensitivity and specificity for diagnosing supraspinatus tendon tears were calculated and compared by using McNemar test. Interobserver and intertechnique variability in the interpretation of supraspinatus tendon tears were calculated as a kappa value. Results: Adding the angled oblique sagittal images to the standard shoulder MRI showed improvement in the sensitivity for diagnosing full-thickness supraspinatus tendon tears and also in the sensitivity, specificity and accuracy for the detection of partial-thickness tears. However, there was no statistically significant difference in all of them between with and without the angled set. Interobserver agreement was substantial to almost perfect and intertechnique agreement was moderate. Conclusion: Adding an angled oblique sagittal plane image to the routine shoulder MRI showed no significantly different diagnostic performance in detecting the partial- and full-thickness supraspinatus tendon tears, compared to MRI without angled oblique sagittal plane.

Purpose: We analyzed the location and type of meniscus tear associated with ACL rupture in order to estimate and prepare whether the meniscus tear is in a repairable location. Materials and Methods: We reviewed 78 cases who had ACL reconstructive surgery due to ACL rupture. We set the period of acute injury on the basis of under 12 months after trauma. The location and type of meniscus tear was analyzed in accordance with MRI findings and arthroscopic findings. Results: The 50 cases of meniscus tear were detected out of the 78 ACL rupture;32 cases were lateral meniscus tears, 24 were medial meniscus tears and 6 cases were both menisci tears. From a total of 56 meniscus tears, 30 cases were longitudinal tears, 22 cases were red-red zone tears and 35 cases(62%) were posterior horn tears. Conclusion: The most common type of meniscus tear associated with ACL rupture war longitudinal tear at the red-red zone or meniscosynovial junction. Majority of the tears located at that place can be healed with conservative treatment, arthroscopic meniscus suture.

The study was conducted to compare the components such as proximate composition, total dietary fiber(TDF) content, acid detergent fiber(ADF) content, lignin, water binding capacity(WBC), amino acid composition and lipid components from brown Job's tears, dehulled Job's tears, brown Yeomjoo and bran of Job's tears. The results from this study are summerized as follows: Total dietary fiber(TDF) content of Job's tears, brown Job's tears, brown Yeomjoo and bran of Job's tears were 2.70%, 3.86%, 4.33% and 13.3% each. Water-binding capacity(WBC) of TDF and ADF were $2.63{\pm}0.02g\;H_2O/g$ TDF and $5.89{\pm}0.15g\;H_2O/g$ ADF each. In amono acids composition of samples, glutamic acid content was the highest and the next was leucine. Chemical score of leucine in dehulled Job's tears was very high(189), in contrast lysine was very low$(22{\sim}23)$ So lysine was a first limitting amino acid in Job's tears and Yeomjoo. Neutral lipid contents were 90.89%-96.55%, glycolipid contents were 2.35%-7.48% and phospholipid contents were very low. The major fatty acids of lipid fractions were palmitic acid. oleic acid and linoleic acid.

Background: To determine the natural progression of conservatively treated rotator cuff tears, we evaluated changes in radiologic and clinical parameters in patients whose recalcitrant tears were neglected after conservative treatment. Methods: A total of 73 patients with recalcitrant rotator cuff tears in spite of conservative treatment were included in this study. We measured changes in tear size and in the extent of fatty infiltration of the rotator cuff by comparing the initial and final follow-up magnetic resonance imagings (MRIs). To determine factors influencing the change in tear size, we collected the medical history of patients taken at the time of initial admission. Results: The average follow-up period was 20.1 months, and the average increase in tear size across this period was 6.2 mm. In terms of steroid injection, we found that the increases in tear size of the steroid injection group (p=0.049) and of the sub-group that had received more than three steroid injections (p=0.010) were significantly greater than that of the non-steroid injection group. Conclusions: We found that the increase in cuff tear size was on average 6.2 mm across the follow-up period, indicating that neglecting cuff tears may cause them to progress into more severe tears. We also observed that a history of steroid injection might be a possible risk factor for a worse prognosis of cuff tears. Therefore, we suggest that patients with rotator cuff tears and a history of steroid injection are recommended aggressive modes of treatment such as surgery.
