Intra-articular ankle fracture (IAF) often leads to post-traumatic osteoarthritis (PTOA), resulting in significant long-term morbidity. While previous research has focused on the inflammatory cytokines and matrix metalloproteinases within the synovial fluid fracture hematoma (SFFH), the immune cell populations within SFFH that contribute to PTOA development remain underexplored. This study aimed to characterize the immune cell populations in SFFH to better understand their role in the inflammatory response and potential for inducing lasting cartilage damage.

Methods: Ankle SF from 54 patients with an acute IAF was analyzed for concentrations of 10 cytokines, 5 matrix metalloproteinases, 2 products of cartilage catabolism, and combined products of heme metabolism. All analytes were correlated with time from fracture and further analyzed for an effect of 3 time subgroups (0-2 days, 3-9 days, and ≥10 days) corresponding to timepoints for clinical ankle fracture interventions.
Background: Antibiotic-impregnated cement nails are used to treat postoperative deep infections after primary intramedullary nail insertion for the treatment of tibial fractures. Few data exist regarding the efficacy of this treatment strategy. We hypothesized that such treatment with antibiotic nails results in a high rate of infection clearance at intermediate follow-up.

The objective of this study was to characterize the acute inflammatory response, both locally and systemically, in joint synovium, synovial fluid (SF), and serum following articular fracture of the ankle. We hypothesized that intraarticular fracture would alter the synovial environment and lead to increased local and systemic inflammation.

Methods: Fifty-nine patients who presented initially with Dupuytren's nodules returned for physical examination at an average follow-up period of 8.7 years (range, 6-15 y).
