Article Abstract
Introduction: Rotational thromboelastometry (ROTEM) is a method for real-time detection of clotting derangements allowing for targeted blood product resuscitation. We sought to determine if coagulopathy profiles differed based on fracture location (comparing pelvic versus tibia and femur fractures), if ROTEM profiles correlated between both total hospital and intensive care unit length of stay (LOS), and if ROTEM profiles correlated with patients undergoing an immediate definitive fixation versus an early damage control approach to care.
Materials And Methods: A retrospective cohort study was performed using data from a level 1 trauma registry database. ICD codes were used to isolate operative lower extremity fractures that had a ROTEM on admission. Two cohorts were created: (1) stratification by fracture location including pelvis, femur, and tibia (n = 498) and (2) stratification by fixation method including external fixation versus early definitive fixation (n = 154). The fracture location cohort assessed length of stay parameters while the fixation cohort assessed fixation approaches with ROTEM profiles.
Results: The majority of fracture location patients with ROTEM APTEM and ROTEM EXTEM profiles were physiologically coagulable with all three fracture locations. Most patients with ROTEM INTEM profiles showed hypocoagulable derangements with femur (75.2%), tibia (68.1%), and pelvic fractures (68.8%). Fractures classified as ROTEM APTEM hypocoagulable indicated a longer hospital LOS (r = 0.282) and ICU LOS (r = 0.510). No correlation was found between coagulopathy profiles and fixation approaches.
Conclusions: ROTEM studies on fracture types showed little consensus on ROTEM profiles correlating to a specific fracture location. ROTEM profiles collected showed limited predictive ability of a patient's hospital and ICU LOS. Early definitive fixation versus external fixation did not correlate between specific ROTEM profiles. Overall, there did not appear to be utility in routine use of ROTEM in fracture patients and this should be limited to those with severe multisystem injuries.

Osteochondromas are the most common benign bone tumors and are frequently discovered incidentally in the metaphyseal regions of long bones during growth. While typically asymptomatic, they may occasionally lead to complications such as neurovascular impingement, mechanical irritation, or pathological fractures. Salter-Harris type II fractures represent the most frequent physeal injuries in pediatric populations, particularly in rapidly growing regions like the distal femur.

Introduction: Tumour-induced osteomalacia (TIO) is rare. At our referral centre, we see a substantial number of TIO. Therefore, we planned to study their profile and treatment outcomes to provide insight in management.

Background: Lateral-sided tibial plateau fractures are most common and can range from minor to very extensive injuries of the lateral plateau. The impact of fracture location and extent on functional outcomes remains unclear. This study aimed to investigate this relationship.

Bedrock fault dislocations significantly influence the rupture instability of rock and soil slopes adjacent to fault zones. Understanding the dynamic processes, kinematic characteristics, and genesis mechanisms of landslides induced by strong seismic fault dislocations is crucial for advancing the theoretical framework of landslide studies. This paper presents a representative experiment simulating the emergence of seismic faults (internal rupture belts within the soil mass) at the shoulders and toes of slopes due to bedrock fault dislocations.

Background: The objective of this study was to evaluate whether dosimetric sparing of uninvolved normal tissues, including skin/subcutaneous flaps, affects acute and late toxicities in preoperative image-guided intensity-modulated radiation therapy (IG-IMRT) for lower extremity soft tissue sarcomas (LE-STS).
Methods: Patients with LE-STS from a phase 2 preoperative IG-IMRT trial (flap-sparing-IMRT, 2005-2009) and a prospectively maintained institutional database (standard-IMRT, 2005-2020) were propensity matched by age, sex, tumor size, grade, location, wound closure, and interval from IG-IMRT to surgery; all received 50 Gy in 25 fractions preoperatively. The primary outcome was major wound complication (MWC).
