Case Background

Patient Duoduo ( pseudonym), 6 years old, due to a tumor perforation near the knee joint in the right lower limb, long-term immobilization is required,to prevent secondary fractures or interference with recovery caused by movement. After evaluation by the pediatric surgery team at a major Class III Grade A hospital in Zhengzhou, Henan, they innovatively adapted our company's hand brace for clinical use on the leg. By making flexible adjustments, they achieved cross-body part adaptation, ensuring both treatment efficacy and patient comfort.

Treatment Highlights

• Flexible Cross-Body Part Adaptation: Originally designed for the hand, the brace was adjusted in terms of strap length and pressure distribution by doctors to precisely fit the leg's tumor area. Imaging shows that the immobilization stability meets the standard.
• Child-Friendly Design: Ultra-light material (65% lighter than traditional plaster) + skin-friendly lining, with breathable holes to reduce skin irritation, and adapted to meet the activity needs of children.
• Dynamic Protection: The elastic straps support staged tightness adjustment, simultaneously adapting to changes in leg swelling and growth, thereby preventing joint stiffness.

Treatment Feedback

• Attending Physician：Although the brace was originally designed for the hand, it can be quickly adjusted to fit the leg, avoiding sensitive tumor areas during surgery. Postoperative immobilization effects are comparable to those of specialized leg braces, significantly improving the child's compliance.
• Feedback from Family Members: The doctor told us that this is a modified hand brace, but after the child put it on, there was no restriction on movement. It is especially quick to remove for dressing changes and examinations, and it does not affect daily wear at all.

Follow-up Results:

• Short Term: Two weeks post-surgery, there were no secondary injuries in the tumor area, and no pressure sores or infections on the skin.
• Long Term: After 7 weeks, the brace was removed, and the passive range of motion in the knee joint was fully retained. The child gradually regained the ability to run and jump, with no complications.

Summary：

This case, centered on flexible cross-body part adaptation and child-friendly design, demonstrates that a hand brace, after clinical modifications, can be safely and effectively used for special leg cases in children. It breaks the limitations of traditional devices to single scenarios and provides a low-cost, highly flexible solution for pediatric orthopedics.
