Three Dimensionally Printed Versus Conventional Casts in Pediatric Wrist Fractures

Area of Science:

• Orthopedic biomaterials
• Digital fabrication in medicine
• Pediatric fracture management

Background:

• Advancements in biomaterials have led to alternatives like 3D-printed orthotics.
• There is limited clinical experience reported for 3D-printed orthoses.

Purpose of the Study:

• To compare radiographic outcomes and patient satisfaction between conventional and 3D-printed casts for acute wrist/forearm fractures.
• To evaluate the efficacy and patient experience of 3D-printed orthoses in pediatric fracture care.

Main Methods:

• Randomized trial involving 23 pediatric patients (8-18 years) with nondisplaced wrist/forearm fractures.
• Comparison of outcomes including X-ray alignment, healing, cast fit, skin condition, ease of care, and patient satisfaction.
• Two treatment groups: conventional fiberglass cast versus 3D-printed orthosis.

Main Results:

• Excellent radiographic healing rates (91% for 3D, 92% for conventional) and full healing (100% for 3D, 92% for conventional).
• No significant difference in skin irritation reported by blinded hand therapists.
• Patients reported significantly better comfort, satisfaction, and ease of care with 3D casts (p<0.05).

Conclusions:

• 3D-printed orthoses provide a viable alternative to conventional casts for pediatric upper extremity fractures.
• These novel orthoses demonstrate potential for enhancing patient experience and comfort during immobilization.
• 3D orthoses ensure appropriate fracture immobilization while improving patient-reported outcomes.
