Suspected Hypersensitivity Reaction to Titanium Screws Following Kalish Osteotomy for Hallux Valgus.

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
Titanium implants are generally regarded as biocompatible and inert; however, hypersensitivity reactions, although uncommon, have been increasingly recognized in orthopedic surgery. We report a case of chronic inflammatory reaction following a Kalish osteotomy for hallux valgus, ultimately attributed to titanium hypersensitivity. A 58-year-old woman underwent fixation of the first metatarsal with two titanium screws. The postoperative course was complicated by wound dehiscence, delayed healing, recurrent granulomatous tissue, and persistent swelling, despite antibiotic therapy. Over the months, two additional surgical procedures were performed, including the removal of a floating bone fragment, followed by biopsy and complete hardware removal. Histopathologic analysis demonstrated reactive bone changes without signs of inflammation or infection, ruling out osteomyelitis. After the removal of the titanium screws, symptoms gradually resolved. At four-year follow-up, the patient remained pain-free with stable bone alignment. This case emphasizes the importance of recognizing titanium hypersensitivity as a potential cause of chronic sterile wound dehiscence and inflammation following orthopedic implant surgery.
