Innovative modified light bulb technique with custom offset curettes for treating precollapsed femoral head osteonecrosis.

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
Osteonecrosis of the femoral head is a devastating disease that accounts for 10-15% of all hip arthroplasty cases in the USA, eventually leading to femoral head collapse and joint destruction. Even the current forms of treatment only slightly slow down the progression of the disease itself. This article describes a modified lightbulb technique, which perfects the method, the instrument, and the flap used in order to ensure hip musculature preservation and improved outcomes. With the direct anterior approach, there is no need to perform surgical dislocation, so the time of the surgery is reduced, as well as the risk of vascular injury. The necrotic bone can be precisely removed using custom-made offset curettes, and a bone graft substitute and autograft can be placed under C-arm guidance. This technique may be beneficial in treating early osteonecrosis of the femoral head by reducing operative time and reducing the risk of complications related to surgical dislocation.
