To report patient characteristics, fracture types, treatment methods, early clinical outcomes and complications of children and adolescents treated for tibial tubercle fractures. Retrospective case series of patients 18 years old and younger treated for tibial tubercle fractures at a single institution from 1995 to 2015. Clinical and radiographic outcomes were reported at minimum six-month follow-up. In 228 patients, 236 tibial tubercle fractures were identified, of whom, 198 (87%) were males. Mean age and BMI was 14.3 years and 25.0, respectively. Pre-existing Osgood-Schlatter disease was identified in 31% cases and was most commonly associated with type I fractures (P < 0.001). Most fractures occurred while participating in athletics (86%). Initial treatment was surgical for 67% fractures. Type III fractures were most common (41%), followed by type I (29%). Type I fractures were most commonly treated nonoperatively (91%) and types II-V fractures were most commonly treated surgically (89%, P < 0.001). Compartment syndrome was identified in 4 (2%) patients, 3 of which had type IV fractures. Most patients returned to sports (88%). Tibial tubercle fractures are sports-related injuries and occur most commonly in adolescent males. They can be associated with pre-existing Osgood-Schlatter disease, a higher than average BMI, and a small but relevant risk of compartment syndrome. Following treatment, most patients return to sports participation.

Interest in the therapeutic potential of bone marrow aspirate concentrate (BMAC) has grown exponentially. However, comparisons among studies and their processing methods are challenging because of inconsistent reporting of protocols, as well as poor characterization of the composition of the initial bone marrow aspirate and of the final products delivered. The purpose of this study was to perform a systematic review of the literature to evaluate the level of reporting related to the protocols used for BMAC preparation and the composition of BMAC utilized in the treatment of musculoskeletal diseases in published clinical studies.A systematic review of the literature was performed by searching PubMed, MEDLINE, the Cochrane Database of Systematic Reviews, and the Cochrane Central Register of Controlled Trials from 1980 to 2016. Inclusion criteria were human clinical trials, English language, and manuscripts that reported on the use of BMAC in musculoskeletal conditions.After a comprehensive review of the 986 identified articles, 46 articles met the inclusion criteria for analysis. No study provided comprehensive reporting that included a clear description of the preparation protocol that could be used by subsequent investigators to repeat the method. Only 14 (30%) of the studies provided quantitative metrics of the composition of the BMAC final product.The reporting of BMAC preparation protocols in clinical studies was highly inconsistent and studies did not provide sufficient information to allow the protocol to be reproduced. Moreover, comparison of the efficacy and yield of BMAC products is precluded by deficiencies in the reporting of preparation methods and composition. Future studies should contain standardized and stepwise descriptions of the BMAC preparation protocol, and the composition of the BMAC delivered, to permit validating and rationally optimizing the role of BMAC in musculoskeletal care.

Clavicle fractures are among the most common fractures occurring in the general population, and the vast majority are localized in the midshaft portion of the bone. Management of midshaft clavicle fractures remains controversial. Although many can be managed nonoperatively, certain patient populations and fracture patterns, such as completely displaced and shortened fractures, are at risk of less optimal outcomes with nonoperative management; surgical intervention should be considered in such cases. The purpose of this article is to demonstrate our technique of midshaft clavicle fixation using minimally invasive intramedullary fixation.
