Without clear reference, the precision of syndesmotic screw placement cannot be guaranteed and malposition of these screws leads to poor results. Therefore, to prevent malpositioning of syndesmotic screws, an improved understanding of the orientation of tibiofibular syndesmosis is essential. We analyzed cross-sectional computed tomography (CT) scans of the foot and ankle to identify precise screw positions for the treatment of syndesmotic injuries. ⋯ The second toe was used as the reference for clarity and applicability. The ideal angle of syndesmotic screw placement in cross-sectional CT images was 18.8±5.6° (mean±standard deviation) and did not differ according to independent variables (P>0.05). In neutral ankle joints with the second toe positioned anteriorly, the ideal angle of syndesmotic screw placement is 18.8°, which is less than that currently in used in conventional methods.

Humeral periprosthetic fractures are a challenging problem and their occurrence has increased, particularly over the last decade. The role of cerclage wires or cables in these fractures includes revisions with longer stems, and augmentation of a plate osteosynthesis in which the stem does not allow additional screw placement or structural bone grafts as supplementary fixation. ⋯ Placing a cerclage wire or cable around the fractured fragments offers a simple and safe procedure to avoid radial nerve injury or palsy in the treatment of complex humeral shaft fractures. This new technique is a simple and safe procedure to place a cerclage wire or cable around the humeral shaft.

Percutaneous scaphoid fixation through either a volar or dorsal approach has the advantage of minor soft tissue damage compared with ORIF, and faster fracture union compared with conservative treatment. However, this technique demands highly intraoperative reliance on X-ray control, including increased radiation exposure and all associated side effects. ⋯ Our results indicate that percutaneous scaphoid fixation with the guide wire placed in a 45° horizontal and vertical angle enables primary moderate positioning, which may lead to quicker adjustment to the ideal position and a decrease of radiation exposure.

Currently Minimally Invasive Plate Osteosynthesis (MIPO) technique for tibial shaft fracture management has gained wide attention. However, an increased intracompartmental pressure after the plate insertion may result in postoperative acute compartment syndrome. We reported the difference of immediate effect of percutaneous plate insertion using 2 approaches of MIPO technique on anterior compartment pressure of the legs. ⋯ When both approaches were compared to each other, the anterolateral plate insertion resulted in higher intracompartmental pressure elevation of the anterior compartment than the anteromedial approach. Surgeon should be more aware of acute compartment syndrome when considering the anterolateral approach in treating close tibial fracture. However, in patients with suspected acute compartment syndrome, close observation and continuous monitoring of the intracompartmental pressure is still imperative for all healthcare provider.
