Pediatric Lower Limb Lengthening Using the PRECICE Nail: Our Experience With 50 Cases

Area of Science:

• Orthopedic surgery
• Pediatric orthopedics
• Biomechanical engineering

Background:

• Intramedullary motorized devices are increasingly used for limb lengthening.
• Limited literature exists on their application in pediatric and adolescent populations.
• This study evaluates outcomes in 50 consecutive pediatric/adolescent cases.

Purpose of the Study:

• To review the outcomes of intramedullary lower limb lengthening in pediatric and adolescent patients.
• To assess the accuracy, reliability, and clinical results of motorized intramedullary nails.
• To evaluate patient-reported outcomes and complications.

Main Methods:

• Retrospective review of 50 consecutive pediatric/adolescent cases (2013-2019).
• Use of PRECICE and STRYDE intramedullary lengthening nails.
• Data collected on nail performance, bone healing, functional recovery, and complications.

Main Results:

• 50 cases performed in 42 patients (mean age 15 years) with a mean discrepancy of 49mm.
• Mean achieved lengthening was 46.5mm with 96% nail accuracy and 90% reliability.
• Favorable ASAMI scores, high patient satisfaction (PROMS), and no significant complications observed.

Conclusions:

• Intramedullary lengthening demonstrates excellent clinical outcomes and high patient satisfaction in pediatric/adolescent populations.
• Thorough preoperative planning, patient education, and a multidisciplinary approach are recommended.
• Motorized intramedullary nails are a safe and effective option for pediatric limb lengthening.
