Abstract
Background: The use of 3D-printed endoprosthesis has been proposed as a viable limb-salvage procedure following total calcanectomy in patients with calcaneal malignancy. However, certain drawbacks persist concerning the prosthetic design. In this case series, we designed a modular endoprosthesis incorporating a novel drainage system, aiming to improve the functional outcomes and to promote wound healing.
Methods: We retrospectively analyzed patients with calcaneal malignancy who underwent 3D-printed modular endoprosthesis reconstruction. Clinically, we evaluated functional outcomes using the 10-cm visual analog scale (VAS) score, the 1993 version of the Musculoskeletal Tumor Society (MSTS-93) score, and the American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot score. Complications were also recorded.
Results: Five male patients met the final inclusion criteria. The median age was 20 years (range 13-47 years). The median follow-up time was 28 months (range, 13-65 months). Median postoperative functional MSTS-93, VAS, and AOFAS scores were 27 points (range, 25-29), 0 points (range, 0-1), and 86 points (range, 83-93), respectively. Wound healing was observed in all patients, and there were no complications related to the endoprosthesis at the last follow-up.
Conclusion: The use of 3D-printed modular endoprosthesis was associated with satisfactory short-term outcomes in patients undergoing calcaneal reconstruction. The incorporation of a novel design featuring an integrated draining system has the potential to enhance wound healing and expedite functional recovery.
期刊介绍:
Foot & Ankle International (FAI), in publication since 1980, is the official journal of the American Orthopaedic Foot & Ankle Society (AOFAS). This monthly medical journal emphasizes surgical and medical management as it relates to the foot and ankle with a specific focus on reconstructive, trauma, and sports-related conditions utilizing the latest technological advances. FAI offers original, clinically oriented, peer-reviewed research articles presenting new approaches to foot and ankle pathology and treatment, current case reviews, and technique tips addressing the management of complex problems. This journal is an ideal resource for highly-trained orthopaedic foot and ankle specialists and allied health care providers.
The journal’s Founding Editor, Melvin H. Jahss, MD (deceased), served from 1980-1988. He was followed by Kenneth A. Johnson, MD (deceased) from 1988-1993; Lowell D. Lutter, MD (deceased) from 1993-2004; and E. Greer Richardson, MD from 2005-2007. David B. Thordarson, MD, assumed the role of Editor-in-Chief in 2008.
The journal focuses on the following areas of interest:
• Surgery
• Wound care
• Bone healing
• Pain management
• In-office orthotic systems
• Diabetes
• Sports medicine
