Abstract
Background and aims
Proximal humerus is a common site of fracture in elderly patients, mainly related to bone fragility. Comorbidities are often present in these patients and may limit the surgical options. Not or minimal invasive treatments are commonly indicated however with variable results. The authors present their experience with conservative approach and percutaneous fixation by K-wires, focusing on their indications and main advantages on this population: mini-invasivity, acceptable reduction and recovery, and low costs.Methods
A study group of 51 consecutive patients with a mean age of 75.5 and affected by severe comorbidities (mainly cardiac, circulatory, pneumologic, neurologic, metabolic, and nephrologic pathologies) were evaluated clinically (ASA score, VAS, muscular strength, Constant-Murley score), and with radiologic analysis: 28 patients were treated by percutaneous fixation, while 23 subjects were treated conservatively.Results
Fractures treated by K-wires fixation healed after a mean interval of 8.2 weeks in all fractures but one, with improvements in mean Constant-Murley score (up to 80.6 points), in mean VAS (2.9), in muscular strength (4.1), and in range of motion. Fractures treated by brace healed in a mean time of 10.2 weeks. Mean Constant-Murley score improved to 76.4 points, VAS to 3.0, muscular strength to 3.8 points, and significant recovery of range of motion.Conclusions
Results of the study confirm that both percutaneous fixation and conservative treatment may represent suitable options for proximal humerus fragility fractures in elderly patients, not candidated to open surgery for severe associated comorbidities.Level of evidence
IV (case series study).
