3-h drain clamping is not effective to reduce total blood loss after primary total knowledge

Purpose@#Total knee arthroplasty (TKA) is a clinically efficacious surgical option for end-stage knee osteoarthritis.However, TKA increases the risk of serious bleeding and blood transfusion. The objective of this study was to evaluate the difference in postoperative blood loss in groups subjected to 3 h of clamping and non-clamping and determine the variations in rate and amount of transfusion after TKA between the two groups. @*Materials and methods@#Propensity score matching of the group subjected to 3-h drain clamping (43 patients;September 2015 to April 2016) and the control group (43 patients; before initiating the clamping method) was performed in patients undergoing unilateral primary posterior stabilized TKA. The two groups were compared. We measured the total drained blood volume until the drain was removed 48 h after surgery, and we compared the preoperative levels of hemoglobin and hematocrit with levels observed on days 1 and 2 after surgery. We also determined the blood transfusion rate and volume as well as the occurrence of clamping-associated complications. @*Results@#In the group subjected to 3-h drain clamping, the mean volume of total drained blood was significantly lower than in the control group (333.8 ± 190.2 mL vs. 839.9 ± 339.8 mL, P <0.001). There was no significant difference in total blood loss between the two groups (1226.9 ± 488.1 mL vs. 1127.1 ± 424.5 mL,P = 0.315), but the hidden blood loss was significantly higher in the 3-h drain clamping group than in the control group (893.1 ± 487.7 mL vs.294.7 ± 531.8 mL, P <0.001). Both the transfusion rate and amount in the 3-h drain clamped group were higher than in the control group but were not statistically significant (30.2% vs. 37.2%, P = 0.494 and 269.8 ± 483.8 mL vs.316.3 ± 158.2 mL,P = 0.648, respectively). No significant differences in complications, including deep vein thrombosis, pulmonary thromboembolism, and oozing, were noted between the two groups (all,P = 1.000). @*Conclusions@#The 3-h drain clamping method after primary TKA using posterior stabilized implant reduced the loss of postoperative drained blood. However, hidden blood loss was significantly higher in the 3-h drain clamping group; as a result, there were no differences in total blood loss and transfusion rate. The clamping method did not significantly alter the complication rate.

Osteoporotic Spinal Compression Fracture and Degree of Vitamin D Deficiency

PURPOSE: The aim of the present study was to evaluate the degree of serum vitamin D deficiency in patients with osteoporotic spinal compression fracture and correlation of serum vitamin D level with several variables. MATERIALS AND METHODS: The medical records of 134 patients with osteoporotic spinal compression fracture, diagnosed at our hospital between October 2008 and June 2011, were reviewed. Serum 25(OH)vitamin D3 was used to evaluate the status of vitamin D level. Serum 25(OH)vitamin D3 level was compared and analyzed according to sex, the number of fractured vertebral body, living environment, and the season of injury. The correlation between vitamin D level and age, bone mineral density, and bone turnover marker were evaluated. RESULTS: In the serum 25(OH)vitamin D3, 87 patients (65%) associated with osteoporotic spinal compression fracture had an insufficient level. Vitamin D level was the lowest in winter, the highest in summer, and significantly higher in the living home than nursing home. Vitamin D level was negatively correlated with age (r=-0.201, p=0.02) and positively correlated with bone mineral density (r=0.217, p=0.012). CONCLUSION: Evaluation of vitamin D level in osteoporotic vertebral compression fracture patients may be helpful in planning the treatment of the patients. For insufficient vitamin D level, the adequate sun exposure and supplement of vitamin D may be used.

Reverse Shoulder Arthroplasty with Tendon Transfer Using Single Incision for Massive Rotator Cuff Tear with Loss of External Rotation / 대한정형외과학회잡지

In patients with massive rotator cuff tears, operative treatment is considered if there is no improvement after conservative treatment. Reverse shoulder arthroplasty is an option among several treatments. However, in cases of massive rotator cuff tears that extend to the teres minor with combined loss of active elevation and external rotation, reverse shoulder arthroplasty alone might not restore the active external rotation. As a consequence, patients continue to feel inconvenienced in performing activities of daily living. Reverse shoulder arthroplasty, with latissimus dorsi and teres major transfer, can restore functional range of motion in forward flexion and in external rotation. Herein, we report a case of massive rotator cuff tear with literature review.

Humerus Shaft Fractures in Leisure Sport 'Flyfish Riding': 4 Cases Report

A fracture of the humeral shaft can occur by direct or indirect injury. Most occur as a result of direct injury mechanisms such as falls from a height, direct blows, and traffic accidents. Recently, the population enjoying watersports for leisure is increasing and 'flyfish riding', in which passengers ride an inflatable raft drawn by a motorboat, may cause humeral shaft fracture as twisting and axial compression forces occur on the humeral shaft while boarding. Accordingly, the incidence of humeral shaft fracture is expected to increase as more people are expected to enjoy leisure sport activities such as 'flyfish riding'. We report 4 cases of humeral fracture that occurred during this activity in the year 2011.
