Successful Revision with INTERTAN for a Blade Cut Through in PFNA Fixation: A Case Report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundImplant cut-out or cut-through remains a common cause of cephalomedullary nail failure and patient morbidity following surgical treatment of intertrochanteric femur fractures. In patients not suitable for conversion to total hip arthroplasty, which can involve long operation times and substantial blood loss, as well as a higher risk of periprosthetic fracture and dislocation postoperatively, revision with another internal fixation is an alternative option. If the femoral head can be preserved as much as possible to avoid eventual joint replacement while the internal fixation failure is solved, the quality of life of patients will be significantly improved. CASE PRESENTATION: This current case describes a successful clinical use of a salvage procedure that allows the surgeon to avoid joint arthroplasty using INTERTAN to solve internal fixation failure caused by cut-through of Proximal Femoral Nail Antirotation-II (PFNA-II). Four years after closed reduction and internal fixation of the right femur, the patient had immobilizing right hip pain and mobility disorder. X-ray examination revealed contraction of the neck of the right femur and cut-through of the helical blade of the PFNA-II. After the revision operation, he recovered well and presented no grown pain or discomfort in weight-bearing. Conventional radiographs at 1-year follow-up showed a healed fracture, with no implant migration.
conclusionMain nail exchange and revision with INTERTAN can be considered a salvage procedure in selected cases to revise a failed fixation with PFNA, which solves internal fixation failure as well as preserves the femoral head.
