Minimally invasive endoscopic treatment for unicameral bone cysts: technique and outcomes in a series of 33 pediatric and adolescent patients.
Article in Journal of orthopaedic surgery and research, 2025. 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
objectiveTo evaluate the clinical efficacy and safety of a minimally invasive endoscopic protocol-combining curettage, sclerotherapy, and injectable bone grafting-in the treatment of unicameral bone cysts (UBCs).
methodsFrom March 2019 to August 2024, 33 pediatric and adolescent patients with UBCs were treated using a standardized minimally invasive endoscopic curettage combined with sclerotherapy and injectable bone grafting at our institution. The cohort included 24 males and 9 females, with a mean age of 10.1 years (range 4-20 years). Patients were followed for an average of 48.4 months (range 12-76 months). Radiographic healing rates, functional score, and complications were assessed.
resultsAccording to the modified Neer classification, complete or partial radiographic healing was achieved in 30 cases (90.9%), while 3 cases experienced persistent or recurrent cyst (9.1%). Almost all patients recovered excellent function. No postoperative pathological fractures or growth plate disturbances were observed during a mean follow-up of 48.4 months. Complications were limited to one episode of transient pain and one case of mild swelling, both self-limiting without intervention. Postoperative hospitalization was brief (mean, 1.2 days), and cosmetic outcomes were excellent, with minimal portal scars, far less conspicuous than those from traditional open procedures.
conclusionEndoscopic minimally invasive surgery combining curettage, sclerotherapy, and injectable bone grafting appears to be a safe and effective option for the management of UBCs in children and adolescents, achieving high healing rates and low complication risks. Nevertheless, given the single-arm design and limited sample size, larger controlled studies with long-term follow-up are needed to confirm these findings.
