Insights

Femoral intramedullary nailing in children can cause hip abnormalities, particularly in those under 13. Damage to the trochanterocervical growth plate is a concern, especially with piriform fossa insertion.

Area of Science:

  • Orthopedic surgery
  • Pediatric orthopedics
  • Biomedical engineering

Background:

  • Femoral intramedullary nailing is a common orthopedic procedure for pediatric fractures.
  • Potential complications, especially concerning growth plate integrity, require thorough investigation.
  • Long-term outcomes of this surgical technique in children are not fully elucidated.

Purpose of the Study:

  • To evaluate the medium- and long-term effects of femoral intramedullary nailing in pediatric patients.
  • To identify specific complications related to the procedure and their influencing factors.
  • To provide recommendations for optimizing surgical techniques and patient selection.

Main Methods:

  • Retrospective study of 34 children undergoing femoral intramedullary nailing.
  • Assessment of medium- and long-term radiographic outcomes, focusing on proximal femur abnormalities.
  • Analysis of potential risk factors including patient age, insertion technique, and implant characteristics.

Main Results:

  • A high incidence of proximal femur abnormalities was observed, including coxa valga and growth arrest of the greater trochanter.
  • These growth plate-related disorders affected 30% of patients, predominantly those under 13 years old.
  • Piriform fossa insertion was associated with a higher frequency of these abnormalities.

Conclusions:

  • Femoral intramedullary nailing in children under 13 is associated with significant risks of trochanterocervical growth plate damage.
  • Alternative management strategies should be considered for younger pediatric patients to mitigate these risks.
  • Surgeons should exercise caution with piriform fossa insertion in pediatric femoral nailing.
