[Design and Application of Distal Radius Anatomical Shape Bracket Splints].

Area of Science:

• Orthopedic surgery
• Biomedical engineering
• Radiology

Background:

• Distal radius fractures are common injuries requiring effective immobilization.
• Traditional splints may lack precise anatomical fit, potentially leading to suboptimal outcomes.
• 3D-MAX software offers advanced design capabilities for patient-specific medical devices.

Purpose of the Study:

• To evaluate the clinical efficacy of 3D-MAX software-designed anatomic shape bracket splints for distal radius fractures.
• To compare the outcomes of anatomic splints with conventional splints in fracture management.

Main Methods:

• Anatomic splints were designed using 3D-MAX software based on healthy volunteer forearm and wrist data.
• Sixty patients with distal radius fractures were randomized into test (anatomic splints) and control (conventional splints) groups.
• Radiographic parameters (palmar dip angle, ulnar fleet angle, radius height) and complication rates were assessed post-treatment.

Main Results:

• The test group showed significantly improved palmar dip and ulnar fleet angles after one week.
• Radius height was significantly greater in the test group at one, three, and six weeks post-treatment.
• The incidence of complications was significantly lower in the test group compared to the control group.

Conclusions:

• 3D-MAX software-designed anatomic splints conform to local anatomy, simplifying the application process.
• These splints provide superior fracture stability and result in fewer complications.
• Anatomic shape bracket splints represent an advancement in distal radius fracture treatment.
