Plain-English summary
A group of 31 dogs underwent total hip replacement surgery using a new technique that involved limiting how deep the femoral canal was prepared. After following up for over a year, only one dog (about 3%) developed a femoral medullary infarction (a type of bone injury) compared to nearly 20% in previous cases using a different method. This significant reduction suggests that being careful with the depth during surgery can help prevent this complication. Overall, the new technique appears to be safer for dogs needing hip replacements.

Abstract
OBJECTIVE: To determine the incidence of femoral medullary infarction after modifying the depth of femoral reaming and filing when performing total hip replacement (THR) using the Zurich Cementless Total Hip Replacement system (ZCTHR). STUDY DESIGN: Case series. ANIMALS: Dogs (n=31) that had ZCTHR (34). METHODS: Thirty-one dogs (34 THR) had ZCTHR (May 2003-September 2006) and with >1 year radiographic (craniocaudal, mediolateral views) follow-up after THR were evaluated for the presence of femoral medullary infarcts. Incidence was compared with a previous study performed before the technique modification. RESULTS: Femoral medullary infarction occurred in 1 femur (2.9%; dog <18 months at THR) compared with 19.5% before the technique change, a significant decrease (P<.001). CONCLUSION: Limiting the depth of reaming and filing of the medullary canal resulted in a significant decrease in the incidence of femoral medullary infarction. CLINICAL RELEVANCE: Depth of reaming and filing the medullary canal should be limited when performing THR using the ZCTHR.
