Abstract

Objective

To report the successful implantation of an osseointegrated transcutaneous amputation prosthesis (OTAP) device following the correction of a distal tibia recurvatum with an intramedullary interlocking nail (ILN) in a 5-year-old Dachshund dog.

Study Design

Case report.

Results

A straight medullary canal was achieved with the opening wedge and stem impaction was performed with relative ease. Radiographic evidence (X-rays and computed tomography scan) 5 months postoperatively showed appropriate callus formation and osseointegration of the endoprosthetic stem, despite visible fissure lines remaining. Force-plate data showed symmetry in gait between prosthetic limb and the contralateral limb. A healthy stoma was achieved during the follow-up period, despite self-limiting skin retraction.

Conclusion

The usage of ILN to correct extreme limb deformity prior to OTAP placement led to greater ease of endoprosthesis impaction. Limb straightening preceding OTAP placement in a chondrodystrophic dog is feasible and no significant lameness was detected despite no surgical intervention to address tibial fissures.
