Objective
To compare the clinical efficacy of the minimally invasive locking plate technique (Philos plate) and interlocking intramedullary nailing technique (TRIGEN intramedullary nail) in the treatment of Neer two-part and three-part proximal humeral fractures.
Methods and materials
The clinical data of 60 patients with Neer two-part and three-part proximal humerus fractures admitted to the hospital from April 2017 to April 2021 were retrospectively analyzed. Thirty-two patients were treated with the minimally invasive locking plate technique (minimally invasive plate group), and 28 patients were treated with the interlocking intramedullary nailing technique (intramedullary nail group). The operation time, intraoperative blood loss, incision length, fracture healing time, and postoperative complications were compared between the two groups. The ASES score and Constant–Murley score were used to evaluate the shoulder joint function of the two groups one year after surgery.
Results
All 60 patients were followed up for 12 to 24 months, with an average of 16 months. There was no significant difference in operation time, intraoperative blood loss, incision length, or fracture healing time between the two groups (P > 0.05). The incidence of postoperative complications in the intramedullary nail group was significantly lower than that in the minimally invasive steel plate group, and the difference between the groups was statistically significant (P < 0.05). There was no significant difference in the ASES score or Constant–Murley score between the two groups one year after surgery (P > 0.05).
Conclusion
The use of the minimally invasive locking plate technique and interlocking intramedullary nailing technique in the treatment of Neer two-part and three-part proximal humerus fractures has the advantages of a small incision, less blood loss, and a high fracture healing rate, and both can achieve satisfactory clinical effects. The internal nail technique is more convenient than the minimally invasive locking plate technique in controlling postoperative complications.
