Mallet Finger Lattice Casts Using 3D Printing.

Area of Science:

• Orthopedics
• Biomedical Engineering
• Materials Science

Background:

• Traditional plaster of Paris casts for mallet finger can lead to complications like skin necrosis if improperly fitted.
• Existing cast options may present inconveniences for timely patient treatment and comfort.

Purpose of the Study:

• To compare the wearability and patient satisfaction of custom 3D-printed mallet finger casts versus traditional plaster casts.
• To evaluate the advantages and disadvantages of 3D printing technology in orthopedic cast fabrication for mallet finger treatment.

Main Methods:

• Production of custom mallet finger casts using both plaster of Paris and 3D printing technology.
• Conducting a wearability assessment to evaluate patient-reported outcomes and comfort.

Main Results:

• 3D-printed casts mitigate risks associated with ill-fitting plaster casts, such as skin necrosis.
• 3D-printed casts are custom-made, smaller, and can be rapidly produced and applied, increasing patient satisfaction.
• Wearability assessment indicated improved patient outcomes with 3D-printed cast solutions.

Conclusions:

• 3D printing technology presents a viable and advantageous alternative for fabricating orthopedic casts for mallet finger treatment.
• Customized, rapidly produced 3D-printed casts enhance patient treatment, comfort, and overall satisfaction compared to traditional methods.
• Additive manufacturing holds significant potential for improving orthopedic device fabrication and patient care in clinical practice.
