Insights

Double plating offers good stability for complex proximal humeral fractures (PHF). This study found favorable radiological and functional outcomes, with a complication rate comparable to existing literature, making it a viable option for younger patients.

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Biomedical Engineering

Background:

  • Proximal humeral fractures (PHF) pose treatment challenges, with limited data on double plating techniques.
  • Assessing the clinical and radiological outcomes of double plating for PHF is crucial for surgical decision-making.

Purpose of the Study:

  • To evaluate the clinical and radiological outcomes and complication rates of double plating in patients with proximal humeral fractures.
  • To determine the effectiveness of double plating as a treatment option for complex PHF.

Main Methods:

  • Retrospective study of 35 patients with unilateral PHF treated with double plating between 2013 and 2019.
  • Radiological assessment of neck shaft angle (NSA) and clinical assessment using Constant-score, Simple Shoulder Test (SST), and Subjective Shoulder Value (SSV).
  • Follow-up periods: radiological (21 ± 16.6 months) and clinical (29.5 ± 15.3 months).

Main Results:

  • No significant difference in NSA between intraoperative and follow-up measurements (p = 0.267).
  • Good functional outcomes: Constant-score (78.5 ± 17), SST (9.3 ± 3.2), SSV (78.8 ± 19.5%).
  • Overall complication rate was 31.4% (14.3% excluding stiffness); avascular necrosis occurred in 5.7%.

Conclusions:

  • Double plating demonstrates good radiological and functional outcomes for complex proximal humeral fractures.
  • The complication rate is comparable to existing literature, suggesting it's a viable alternative to fracture arthroplasty, particularly for younger patients.
