Surgeon Referral for Extraction of Inadvertent Deep and Nonpalpable Contraceptive Implants That Place Major Peripheral Nerves at Risk: A Systematic Review of Case Reports and Case Series.
Review in The archives of bone and joint surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objectives: Implantable contraceptive implants placed at the medial arm are often misapplied relatively deep, sometimes in muscle or adjacent to neurovascular structures. We reviewed the available evidence regarding non-palpable medial arm implants and factors associated with deep application to help inform specialists who may be asked to assist with removal in order protect nearby nerves. Methods: Following PRISMA guidelines, the authors systematically reviewed PubMed, Embase, and Cochrane Library for case series and reports of complications associated with the removal of nonpalpable contraceptive implants in September of 2025. Rates and features of routine and problematic implant removal were studied. Factors potentially related to deep placement were identified. The NIH tool for case series (2021) was used to assess study quality. Results: We identified 16 case series and 10 case reports related to problematic implant removal from an initial search of 219 publications. In a series of routine insertions and removals, nonpalpable surgical implant removal was uncommon. Compared to routine removal, problematic removal was associated with subfascial implants, intramuscular implants, and previous attempts. A subset of implants was removed in the operating room. Transient paresthesia of the ulnar, median, and medial antebrachial cutaneous nerves was common after surgical removal of deep nonpalpable implants. Factors potentially associated with non-palpable implants included provider training, time since insertion, greater BMI, and weight gain during implant use. Among the 10 case reports, 6 orthopedic surgeons and one plastic surgeon performed removal. Conclusion: Hand surgeons may receive requests for assistance removing deep, nonpalpable contraceptive implants in order to limit the potential for neurovascular damage given that the medial arm insertion site is associate with the possibility of injury to adjacent to major nerves.
