Background

There are a few good options for restoring bone defects in the hand and foot.

Purpose

(1) What are the functional outcomes of patients with hand or foot tumors who were treated with tumor resection and reconstruction with a 3D-printed custom prosthesis?

Methods

Based on this, 93 patients were eligible; a further 77 were excluded because they received nonoperative treatment such as chemoradiation, resection without reconstruction, reconstruction using other materials, or ray amputation; another three were lost before the minimum study follow-up of 2 years and two had incomplete datasets, leaving 11 for analysis in this retrospective study.

Results

of 30

median function score was near the top of the scale, so function was good

n = 276 patients

More results

Seven of 11 patients experienced postoperative complications, primarily including hyperextension deformity and joint stiffness (three patients), joint subluxation (two), aseptic loosening (one), broken stem (one), and broken plate (one), but no infection or local recurrence occurred.

More results

These prostheses were revised to a second-generation prosthesis with joint and stem, leading to improved dexterity.

The cumulative incidence of implant breakage and reoperation in the Kaplan-Meier analysis was 35% (95% CI 6% to 69%) and 29% (95% CI 3% to 66%) at 5 years, respectively.

Conclusion · 1 of 3

These preliminary findings suggest that 3D implants may be an option for reconstruction after resections that leave large bone and joint defects in the hand and foot.

Conclusion · 2 of 3

Although the functional results generally appeared to be good to excellent, complications and reoperations were frequent; thus, we believe this approach could be considered when patients have few or no alternatives other than amputation.

Conclusion · 3 of 3

Future studies will need to compare this approach to bone grafting or bone cementation. LEVEL OF EVIDENCE: Level IV, therapeutic study.
