BACKGROUND: Increased frequency of comminuted clavicle mid-shaft fractures and importance of functional satisfaction through early joint exercise has resulted in higher emphasis on surgical treatments. This study aimed to evaluate the clinical radiological results of treatment of clavicle mid-shaft fractures by open reduction and internal fixation using a plate with a small incision. METHODS: The subjects of this study were 80 clavicle mid-shaft fracture cases treated with internal fixation using a plate from October 2010 to July 2014. Clavicle mid-shaft fractures were internally fixated using anatomical plates or locking compression plates. Achievement of bone union, union period, and clavicle length shortening were evaluated radiologically, and clinical assessment was done by using Constant and University of California at Los Angeles (UCLA) scores. RESULTS: All 80 cases were confirmed to have achieved bone union through radiographs with an average union period of 10.9 weeks (range: 7–18 weeks). The average clavicle length of shortening in the affected side was 1.8 mm (range: 0–17 mm). The average UCLA score and Constant score were 33.6 (range: 25–35) and 92.5 (range: 65–100), respectively. Regarding complications, four cases reported skin irritation by metal plates, and one case reported a screw insertion site fracture due to minor trauma history. CONCLUSIONS: We were able to induce successful bone union and obtain clinically satisfactory results in displaced mid-shaft fractures of the clavicle without major complications such as nonunion through treatment of internal fixation using a plate.

Rotator cuff tear is a common cause of shoulder pain and disability in adults. Due to the various nature of progression of rotator cuff tears and the complex biomechanics of the shoulder joint, repair and treatment of large-to-massive tears are challenging for many surgeons. Despite the recent popularity of reverse total shoulder arthroplasty as a treatment option for large-to-massive irreparable rotator cuff tears, biological and mechanical repair augmentation has also shown promise as a viable treatment option. The purpose of this study was to briefly summarize and review current studies on the assessment and arthroscopic treatment of large-to-massive rotator cuff tears, whether repairable or irreparable, to aid in developing a consensus on future treatment directions.

Milwaukee shoulder syndrome (MSS) is a rare disease in which joints are destroyed and occurs mainly in elderly women. We describe rapidly progressive MSS with complete destruction of the shoulder joint within 2 months. An 80-year-old woman visited the outpatient clinic with shoulder pain for 2 weeks. rotator cuff tear arthropathy was diagnosed, and nonsteroidal anti-inflammatory drugs were prescribed. Two months later, her shoulder pain worsened without trauma. Shoulder swelling and tenderness, and arm lifting inability were observed. Complete humeral head disruption was observed by radiography. We diagnosed MSS based on the presence of serohematic and noninflammatory joint effusion, periarticular calcific deposits, and rapid joint destruction, and initiated conservative treatment. When initially treating elderly patients with shoulder arthropathy, it is advisable to perform short-term follow-up and to consider the possibility of crystal-induced arthropathy.

Despite the advances in total ankle replacement (TAR), TAR has emerged as a promising alternative to ankle arthrodesis, particularly in severe ankle arthritis. Restoring ankle stability and alignment is the most important technical consideration and the goal of TAR. Hence, additional procedures, such as soft tissue balancing and osteotomies, are often critical parts of surgical planning. This article reviews the basics of joint balancing, offering suggestions on procedure selection for ligamentous balancing and varus and valgus malalignment in TARs.

BACKGROUND: The Coapresta 2000 (Sekisui Medical CO., LTD, Japan) is a fully automated random-access multiparameter hemostasis coagulation analyzer, which is equipped with a photo-optical clot detection unit and a cap-piercing system. It is able to perform clotting time assays as well as colorimetric assays (synthetic substrate method and latex turbidimetric method). In this study, we evaluated the analytical performance of the Coapresta 2000 for coagulation test items and compared with that of the ACL-TOP (Instrumentation Laboratory, Lexingtion, MA, USA) analyzer, which is currently used for routine coagulation test items in our hospital. METHODS: The Coapresta 2000 was evaluated with respect to its technical characteristics in the determination of 8 routine coagulation test items: prothrombin time, activated partial thromboplastin time, fibrinogen, fibrin-degradation product (FDP) antithrombin III, D-dimer, factors VIII and IX. Analyse-it (Analyse-it Software Ltd, UK) and SigmaStat (Systat Software, Inc., USA) were used for statistical analysis between items on the Coapresta 2000 and the ACL-TOP analyzer. RESULTS: The intra-assay and inter-assay coefficients of variation (CV) were below 5% for both groups of samples having values within the reference interval and outside the reference interval. Significant interference was observed with hemolytic and icteric samples. Carryover was not detected. The results obtained by Coapresta 2000 were well correlated with those obtained by the ACL-TOP analyzer (r2 in the range from 0.781 to 0.969). CONCLUSIONS: We concluded that Coapresta 2000 analyzer was well correlated with ACL-TOP analyzer for the routine coagulation test items tested.

Approximately 80-85% of D-negative (D-) persons produce anti-D antibodies after exposure to D-positive (D+) red blood cells (RBCs). Previously, anti-D was the most commonly detected Rh antibody, but its incidence has greatly decreased due to the prophylactic use of Rh immunoglobulin (RhIG). Anti-D antibody formation may occur following RhD-incompatible organ transplantation when D- recipients are exposed to D+ RBCs that originate from a donor organ. As a large volume of donor blood may be contained within the transplanted organ, the use of a large amount of RhIG is required in RhD-incompatible liver transplantation. Here, we describe the use of a large amount of RhIG to treat a patient following RhD-incompatible liver transplantation. This patient was a 71-yr-old woman with hepatitis C virus-related liver cirrhosis, who had an A/D- blood type. The donor was her grandson, whose blood type was O/D+. The recipient's preoperative anti-D antibody test was negative. One unit of O/D- irradiated leukoreduced RBCs and three units of A/D- fresh frozen plasma were transfused during liver transplantation. An equal amount (12,000 IU) of RhIG was infused intravenously, immediately after liver transplantation and a second time on post-operation day 1. The anti-D titer was 1:64 on the first post-operation day, and had increased to 1:128 by the following day. By 1 month after the surgery, the titer had decreased to 1:4. In this case of liver transplantation, RhIG was actively used to prevent RhD sensitization and the subsequent occurrence of adverse events associated with RhD-incompatible liver transplantation.

BACKGROUND: ABO blood grouping reagent verification is essential to ascertain safe blood transfusions. However, the research use of donated blood products has been hampered in Korea by the blood transfusion law and management policies. In this study, we developed cryopreserved red blood cell (RBC) panels utilizing the high glycerol method to verify the ABO and D blood grouping reagents. In addition, we evaluated the stability of ABO and D antigenicity. METHODS: Fresh blood was frozen by the high glycerol method, aliquoted and cryopreserved in 2 mL cryotubes. Twenty-four vials of bloods with types A (n=5), B (n=5), AB (n=4) and O (n=10) for ABO RBC panels, and eleven vials of blood types D positive (n=5), D negative (n=5) and D weak (n=1) for D RBC panels were established. Potency, avidity and specificity tests were carried out with four different commercial ABO and D blood grouping reagents. RESULTS: The potency of cryopreserved RBCs after thawing showed no statistical difference compared with pre-freezing RBCs. Avidity time measurements were 5 seconds in ABO blood and 20 seconds in D positive blood. Specificity test uniformly showed 100% specificity. When thawed RBCs were stored at 4degrees C for 7 days, the potency test measured at intervals of 2 days showed no variation. CONCLUSION: Cryopreserved RBC panels produced by the high glycerol method showed excellent results in stability test with reagents produced by manufacturers in Korea. Therefore, these panels can be utilized as a reliable method of verifying blood grouping reagents.
