Purpose; Delayed presentation of lateral condylar fractures of the humerus is relatively common in the developing regions of the world. These fractures are difficult to manage because of the displacement and fibrosis around the condylar fragment secondary to the delay. There is a paucity of literature concerning the management of these fractures. An oft repeated finding is the requirement of extensive dissection around the fragment for proper reduction. The purpose of this study was to assess the efficacy of surgical management of lateral condylar fractures with delayed presentation. Methods; We assessed the results of lateral condylar fracture fixation in 20 cases with delayed presentation. Results; The lateral condylar fractures in patients with a delayed presentation can be managed surgically with good results. Conclusions; Open reduction and internal fixation should continue to be the method of choice for the management of lateral condylar fractures which report late for management.

BACKGROUND: Major orthopedic surgical procedures, including spinal fusions, require 2 or 3 units of transfusion. In this study, we evaluated the usefulness of autologous transfusion by comparing the postoperative infections, the pre- and postoperative serological changes, the amount of transfusion during the operation and the segmented estimated blood loss of the patients who received spinal fusion surgery. METHODS: We analyzed 106 patients who were undergoing spinal fusion surgery and among them, 69 patients were operated on with using autologous transfusion, while 37 cases were operated on with using homologous transfusion. RESULTS: The segmental estimated blood loss was approximately 574.4+/-131.8 mL in group 1 and 635.3+/-250.1 mL in group 2. The mean number of transfused units in the autologous transfusion group was 2.1+/-0.3 units and this was 3.5+/-0.6 units in the homologous transfusion group. There was no significant statistical difference in the hemoglobin level or the complications between the two groups, yet the duration of fever in the group with homologous transfusion was 3.0+/-0.4 days, which was increased compared to that of group 1 (1.4+/-1.3 days). CONCLUSION: The total amount of transfusion and blood loss for the patients who were operated on using autologous transfusion were less, as compared to those for the patients who were operated on with homologous transfusion, and the patients with homologous transfusion showed a significantly decreased duration of fever. It seems that autologous transfusion is a way to shorten the duration of fever and increase the satisfaction of the patients.

Ultrasonic scalpel has the advantages of less bleeding, less damage to surrounding tissue, early healing, etc. The applications of ultrasound in medical surgery include incision and hemostasis, phacoemulsification, tumor aspiration, fat aspiration, and bone cutting. In this paper, the principles, development, characteristic, key technology and clinical application of different ultrasonic scalpel in the world are introduced, and the domestic application and future development of ultrasonic scalpel are prospected.

BACKGROUNDFor partial-thickness tears of the rotator cuff, double-row fixation and transtendon single-row fixation restore insertion site anatomy, with excellent results. We compared the biomechanical properties of double-row and transtendon single-row suture anchor techniques for repair of grade III partial articular-sided rotator cuff tears.

METHODSIn 10 matched pairs of fresh-frozen sheep shoulders, the infraspinatus tendon from 1 shoulder was repaired with a double-row suture anchor technique. This comprised placement of 2 medial anchors with horizontal mattress sutures at an angle of ≤ 45° into the medial margin of the infraspinatus footprint, just lateral to the articular surface, and 2 lateral anchors with horizontal mattress sutures. Standardized, 50% partial, articular-sided infraspinatus lesions were created in the contralateral shoulder. The infraspinatus tendon from the contralateral shoulder was repaired using two anchors with transtendon single-row mattress sutures. Each specimen underwent cyclic loading from 10 to 100 N for 50 cycles, followed by tensile testing to failure. Gap formation and strain over the footprint area were measured using a motion capture system; stiffness and failure load were determined from testing data.

RESULTSGap formation for the transtendon single-row repair was significantly smaller (P < 0.05) when compared with the double-row repair for the first cycle ((1.74 ± 0.38) mm vs. (2.86 ± 0.46) mm, respectively) and the last cycle ((3.77 ± 0.45) mm vs. (5.89 ± 0.61) mm, respectively). The strain over the footprint area for the transtendon single-row repair was significantly smaller (P < 0.05) when compared with the double-row repair. Also, it had a higher mean ultimate tensile load and stiffness.

CONCLUSIONSFor grade III partial articular-sided rotator cuff tears, transtendon single-row fixation exhibited superior biomechanical properties when compared with double-row fixation.
