Background: As there is substantial variation in the classification and diagnosis of lateral clavicle fractures, proper management can be challenging. Although the Neer classification system modified by Craig has been widely used, no study has assessed its validity through inter- and intrarater agreement. Purpose: To determine the inter- and intrarater agreement of the modified Neer classification system and associated treatment choice for lateral clavicle fractures and to assess whether 3-dimensional computed tomography (3D CT) improves the level of agreement. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: Nine experienced shoulder specialists and 9 orthopaedic fellows evaluated 52 patients with lateral clavicle fractures, completing fracture typing according to the modified Neer classification system and selecting a treatment choice for each case. Web-based assessment was performed using plain radiographs only, followed by the addition of 3D CT images 2 weeks later. This procedure was repeated 4 weeks later. Fleiss κ values were calculated to estimate the inter- and intrarater agreement. Results: Based on plain radiographs only, the inter- and intrarater agreement of the modified Neer classification system was regarded as fair (κ = 0.344) and moderate (κ = 0.496), respectively; the inter- and intrarater agreement of treatment choice was both regarded as moderate (κ = 0.465 and 0.555, respectively). Based on the plain radiographs and 3D CT images, the inter- and intrarater agreement of the classification system was regarded as fair (κ = 0.317) and moderate (κ = 0.508), respectively; the inter- and intrarater agreement of treatment choice was regarded as moderate (κ = 0.463) and substantial (κ = 0.623), respectively. There were no significant differences in the level of agreement between the plain radiographs only and plain radiographs plus 3D CT images for any κ values (all P > .05). Conclusion: The level of interrater agreement of the modified Neer classification system for lateral clavicle fractures was fair. Additional 3D CT did not improve the overall level of interrater or intrarater agreement of the modified Neer classification system or associated treatment choice. To eliminate a common source of disagreement among surgeons, a new classification system to focus on unclassifiable fracture types is needed. [ABSTRACT FROM AUTHOR]

Conclusion: Even though the use of TachoComb does not decrease pain after tonsillectomy, it is safe and useful to reduce bleeding after tonsillectomy. Objectives: Sealing the post-tonsillectomy wound would be expected to reduce pain and bleeding by decreasing the exposure of the traumatized tissue and sensory nerves. TachoComb is a powerful topical hemostatic agent. The objectives of this study were to evaluate the effect of TachoComb on reduction of pain and bleeding after tonsillectomy. Methods: A prospective randomized double-blind study was performed on 120 pediatric patients undergoing adenotonsillectomy. The patients were randomized into two groups: use/non-use of TachoComb. In the study group, each tonsillar bed was covered with a TachoComb strip at the end of operation. No hemostatic agents were used in the control group. After surgery, patients were monitored for pain, bleeding, oral intake, medication administration, activity, and complications using a 10-day diary. Results: In all, 110 patients returned and filled in the diary. The use of TachoComb did not decrease pain, reduce the use of analgesic drugs or speed recovery to normal everyday life. Post-surgery bleeding was not experienced by any of the TachoComb patients, but occurred in five of the control patients. The result had borderline statistical significance ( p < 0.1).
