Regional anesthesia strategies for proximal humerus fracture surgery: anatomical considerations, diaphragm-sparing techniques, and expert perspectives-a narrative review.
Review in Langenbeck's archives of 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
backgroundProximal Humerus Fractures (PHFs) are increasingly common, particularly in elderly patients with osteoporotic bone. Surgical and anesthetic management significantly influence outcomes, yet evidence guiding optimal strategies remains limited. Regional Anesthesia (RA) offers effective analgesia, opioid sparing, and the potential to avoid general anesthesia in frail or high-risk patients. This narrative review summarizes current knowledge, highlights diaphragm-sparing approaches, and integrates expert clinical insights to provide practical recommendations for anesthesiologists managing PHF surgery.
methodsA narrative review was conducted using a structured non-systematic search of PubMed, Embase, and Scopus (January 2000–November 2025). Eligible studies included adults undergoing PHFs surgery with RA and reporting clinical outcomes; case reports, purely anatomical studies, non-surgical analgesia, and non-PHF procedures were excluded. Nine studies met inclusion criteria. Additional references provided anatomical, surgical, and anesthetic context. Orthopedic data were reviewed to contextualize anesthetic strategies, and an “Expert Opinion” section integrated multidisciplinary insights.
resultsAmong the nine PHF-specific studies, evidence was limited and heterogeneous, focusing mainly on analgesic efficacy, technical feasibility, and respiratory safety rather than long-term outcomes. Interscalene Brachial Plexus Block (ISBPB) provided effective analgesia but was frequently associated with phrenic nerve involvement. Diaphragm-sparing approaches—such as Superior Trunk Block (STB), infraclavicular techniques, and selective suprascapular and axillary nerve blocks—may reduce respiratory impairment while maintaining acceptable analgesia. Only a minority of studies evaluated continuous RA, reporting prolonged postoperative pain control and opioid sparing in small cohorts. Additional literature supported tailoring block selection to fracture pattern, surgical approach, and patient comorbidities. Expert perspectives emphasized pragmatic, patient-centered strategies, particularly for high-risk or frail patients.
conclusionsRA is an important component of PHFs surgery, although PHF-specific evidence remains limited. Integrating available data, contextual literature, and expert experience supports an individualized approach balancing analgesic efficacy with safety. Diaphragm-sparing and selected continuous techniques may be considered in patients at increased respiratory risk. Further well-designed studies are needed to refine patient selection and evaluate functional and long-term outcomes.
