Open Reduction and Internal Fixation of Both-Bones Forearm Fractures*
Bibliographic record
Abstract
Compared with closed reduction or older fixation methods, open reduction and compression plate fixation has dramatically improved the outcomes of displaced diaphyseal forearm fractures. However, the procedure can be technically demanding, with implant choice, surgical approach, accuracy of reduction, and sufficient fracture stability to allow early postoperative motion all having been shown to affect outcome. The procedure is performed with the following steps:The patient is positioned supine on the operating room table with the arm on a hand-table and a tourniquet applied to the upper arm.After skin preparation and draping, a longitudinal incision is made over the volar aspect of the forearm between the flexor carpi radialis tendon and the radial artery, centered over the radial fracture site.The interval between the flexor carpi radialis and the radial artery is developed, and, depending on the location, the deeper musculature is reflected from the bone adjacent to the fracture site, which is debrided of hematoma, irrigated, and cleaned.The fracture is reduced and is provisionally fixed with a Kirschner wire, or lag screw if possible. A small-fragment compression plate that provides at least three bicortical screws proximal and distal to the fracture is selected and is applied with one screw each proximally and distally.After provisional fixation of the radius, a similar process is carried out for the ulna, with use of an approach along the subcutaneous border between the flexor carpi ulnaris and extensor carpi ulnaris. Then the forearm is carefully examined clinically and radiographically to ensure accurate reduction of the fractures and motion/stability of the elbow and wrist.The remainder of the screws are inserted, the fascia of the forearm is not closed, and a standard closure of subcutaneous tissue and skin is performed.Open fractures of the forearm can typically be treated with irrigation, debridement, and immediate fixation. A volar approach is preferred over a dorsal approach for most radial fractures to minimize the risk to the posterior interosseous nerve. Anatomic reduction, especially restoration of the radial bow, is critical for restoration of motion and function. Bone-grafting is rarely indicated, even in comminuted fractures. A rapid return to function, union rates of ≥95%, restoration of forearm strength and stability, and low complication rates have been reported in multiple studies of this technique.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
