Is Compressive Intramedullary Nailing an Effective Method in Aseptic Humerus Nonunions without Bone Defects?

Area of Science:

• Orthopedic Surgery
• Traumatology
• Bone Healing

Background:

• Nonunion of humerus fractures presents a significant clinical challenge.
• Various surgical techniques exist, but optimal treatment remains debated.
• Aseptic nonunions without bone defects require effective fixation and biological enhancement.

Purpose of the Study:

• To evaluate the efficacy of compressive intramedullary nailing for aseptic humeral nonunions.
• To assess radiological union and functional outcomes after revision surgery.
• To analyze results in patients without bone defects treated with a single technique.

Main Methods:

• Retrospective cohort study of 15 patients with humeral nonunion.
• Treatment involved compressive intramedullary nailing with maximal bone contact.
• Radiological union assessed by RUSHU criteria; functional outcomes by Constant-Murley score.

Main Results:

• Radiological union achieved in 14 of 15 patients within 16.6 weeks.
• Excellent or good functional outcomes reported in 13 patients.
• Bone grafting utilized in 12 patients; no implant failures observed.

Conclusions:

• Compressive intramedullary nailing is a valuable technique for aseptic humeral nonunion.
• The method demonstrates high union rates and positive functional results.
• It offers a reliable solution for nonunions without bone defects.
