Patients managed non-operatively, with closed reduction percutaneous fixation, acute total hip arthroplasty, staged ORIF and patients with operations with any blood loss prior to acetabular ORIF were excluded.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Outcome measures and comparisons: &lt;/strong&gt;The primary outcome was differences in transfusion requirements between patients who had early fixation (within 48 hours) and those who had delayed fixation (after 48 hours).

Fourteen (17%) patients had no MRI ITE, 11 (14%) patients had &lt;50% MRI ITE, and 56 (69%) patients had ≥50% MRI ITE. The presence of CL on CT corresponded to any MRI ITE (&lt;50% and ≥50%) with sensitivity of 55.2%, specificity 100%, positive predictive value (PPV) 100%, and negative predictive value (NPV) 31.8%. In patients with MRI ITE 50% or greater only and CL presence, specificity was 92%, and sensitivity was 62.5%. Presence of ST on CT was associated with any MRI ITE with sensitivity of 34.3%, specificity 100%, PPV 100%, and NPV 24.1%. Patients with MRI ITE 50% or greater and ST presence, specificity was 96% and sensitivity was 39%.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;In patients with apparent isolated greater trochanteric fractures, the presence of curvilinear IT and subtrochanteric density in the medullary bone in the injured femur on pelvis CT was highly predictive of ITE. Patients with these CT findings in the injured femur on pelvis CT can be assumed to have ITE and treated accordingly, obviating the need for MRI. The absence of the curvilinear IT and subtrochanteric densities did not rule out possible ITE, and MRI can be further considered in this population.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Level of evidence: &lt;/strong&gt;Diagnostic Level III.

Failure to accurately restore tibial alignment may lead to malrotation, poor functional outcomes, and reoperation to correct rotational deformity. No consensus currently exists regarding the optimal technique for intraoperative measurement of tibial torsion in patients undergoing tibial fracture fixation. This article describes a technique using a mobile C-arm fluoroscope to intraoperatively measure torsion of the contralateral uninjured leg to guide surgical fixation of the fractured tibia. The rotational profile of the uninjured leg is produced by obtaining a perfect lateral of the knee followed by an ankle mortise view. A series of patients is also presented that demonstrates the reproducibility of the technique and demonstrates the range of tibia torsion in patients with tibia fractures.</p>","PeriodicalId":16644,"journal":{"name":"Journal of Orthopaedic Trauma","volume":" ","pages":"302-307"},"PeriodicalIF":1.6,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143468077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients treated with anterior internal fixation also experienced fewer mean ICU days (6.0 ± 8.8 vs. 9.8 ± 16.3, P = 0.0213), ventilator days (3.5 ± 8.2 vs. 6.9 ± 15.9, P &lt; 0.0081), and hospital days (18.7 ± 16.2 vs. 31.2 ± 26.7, P &lt; 0.01) and incurred less hospital charges ($278,563.29±$261,602.35 vs. $580,625.98±$503,067.98, P &lt; 0.01).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;Patients who received anterior and posterior internal fixation of their unstable pelvis fractures were more likely to discharge to home than patients treated with anterior definitive external fixation and posterior internal fixation.
