The average BMI of the G3 group was 24 kg/m2 (15-35 kg/m2) compared to 27 kg/m2 in the G4 group (17-41 kg/m2) (p = 0.004). There were no significant differences when comparing diabetes, smoking status, or mechanism of injury between groups (p>0.05). There was no significant difference when comparing the average TAD between the G3 (10 mm) and G4 (9.5 mm) (p = 0.39). There was no significant difference in reduction quality between the G3 (46 good reductions) and the G4 (42 good reductions) groups (p = 0,85).At 6 weeks, the G4 (5 mm) had significantly greater lag screw slide compared to the G3 (3 mm) (p = 0.016). At 12 weeks, the G4 (7 mm) also had significantly greater lag screw slide when compared to the G3 (4 mm) (p = 0.004). There was no significant difference in lag screw slide for the 125° implant between the G3 and G4 groups at 6-weeks (3 mm versus 5 mm, p = 0.44) or 12 weeks (4mm versus 6 mm, p = 0.14). Regarding the 130° implant, the G4 had significantly greater slide compared to the G3 at both at 6-weeks (5 mm versus 3mm, p =0.03; 95% CI -6.07 to -0.41) and 12-weeks (8 mm versus 4 mm, p = 0.03; 95% CI -5.65 to -0.26). The G4 group had 7 revision procedures performed (3 lag screw exchanges for iliotibial band irritation and 4 revision arthroplasties for lag screw slide, fracture shortening, iliotibial band irritation, abductor malfunction, and leg length discrepancy) compared to 1 revision procedure (lag screw exchange for iliotibial band irritation) in the G3 group (p = 0.04).</p><p><strong>Conclusions","PeriodicalId":16644,"journal":{"name":"Journal of Orthopaedic Trauma","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142950498","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}

In addition, it is becoming clear that rib nonunions are not rare, likely more than 5% of rib fractures. No subspecialty is better equipped to address such painful conditions than orthopaedic surgery. Likewise, there are a plethora of other posttraumatic problems that patients face, from intercostal neuralgia, pleural herniation, rib synostosis, and costal margin and sternal injuries that do not heal properly, which require treatment solutions. This emerging new field of surgery is optimized by an interdisciplinary approach, between general and orthopaedic trauma surgeons, and between thoracic, anesthesia, and rehabilitation specialists. This article emphasizes the workup and operative treatment of painful rib and sternal nonunions, in particular, and familiarizes the orthopaedist with other cold skeletal trauma in general.

Although blocking screws are described to facilitate reduction, they risk impeding subsequent implant fixation. This article introduces an innovative Temporary Reduction Assisting Corridor Constraint Wires (TRACC-wires) technique to safely correct multiplanar deformities without limiting fixation options. A retrospective case series of 22 patients showed that TRACC-wires effectively facilitated anatomic alignment intraoperatively that was maintained after wire removal. Compared with other methods, advantages include (1) the ability to easily redirect, reposition, or remove (given instant access to the blocking device), (2) malleability of the wires during nail insertion, (3) small bony footprint, and (4) versatility for patient-specific correction.

The latter function is accomplished through various muscular attachments and rib articulations with both the axial spine posteriorly and the sternum anteriorly. The accessory muscles of inspiration rely on the downward slope and outward curve of each rib, which when contracted move the ribs upward and outward, in turn forcing the sternum anterior and increasing the thoracic volume. Ribs are also classified as true, false, or floating based on their attachment anteriorly to the costal cartilage and sternum. Ribs 1-7 are considered true ribs as their costal cartilage directly articulates with the manubrium and sternum. Ribs 8-10 are considered false ribs because their costal cartilage connects to the cartilage of the immediately superior rib instead of the sternum itself. This complex cartilaginous structure is referred to as the costal margin, which provides attachments for the diaphragm and various abdominal muscles. Although historically thought to be a consistent structure, its variable nature has recently been defined in cadaveric studies. Ribs 11 and 12 are considered floating ribs because they have rudimentary cartilage caps and are not attached to the sternum at all. The sternum comprises the manubrium, body, and xiphoid process.
