To evaluate owner adherence to recommendations for follow-up examination of dogs and cats following orthopedic procedures and identify factors associated with adherence versus nonadherence.
Medical records of 485 dogs and cats that underwent orthopedic surgery.
Cases were categorized as urgent or elective. Information obtained from the medical records consisted of species, age, body weight, proximity to the hospital, procedure cost, recommendations for coaptation, use of financial aid, and number of owners. Cases were considered adherent to follow-up recommendations if, at the latest visit or communication, no further visits were recommended. Cases were considered nonadherent if owners did not return for recommended follow-up visits.
Overall adherence to follow-up recommendations was 65.8% (319/485). Elective cases were 1.6 times as likely to be adherent to follow-up recommendations as were urgent cases, dog cases were 2.4 times as likely to be adherent as were cat cases, and cases with multiple owners listed were 2.1 times as likely to be adherent as were cases with 1 owner listed. Distance from the hospital had a statistically significant association with adherence, but the effect was not clinically important. Age, weight, coaptation, procedure cost, and use of financial aid were not significantly associated with adherence.
CONCLUSIONS AND CLINICAL RELEVANCE
The percentage of dogs and cats lost to follow-up following orthopedic surgery at an academic veterinary teaching hospital was substantial (166/485 [34.2%]). Efforts to improve follow-up adherence are especially indicated for animals undergoing urgent procedures, animals with single owners, and cats.
To assess the feasibility and accuracy of using 2 methods for reduction and alignment of simulated comminuted diaphyseal tibial fractures in conjunction with 3-D–printed patient-specific pin guides.
Paired pelvic limbs from 8 skeletally mature dogs weighing 20 to 35 kg.
CT images of both tibiae were obtained, and 3-D reconstructions of the tibiae were used to create proximal and distal patient-specific pin guides. These guides were printed and used to facilitate fracture reduction and alignment in conjunction with either a 3-D–printed reduction guide or a linear type 1A external fixator. Postreduction CT images were used to assess the accuracy of pin guide placement and the accuracy of fracture reduction and alignment.
The 3-D–printed guides were applied with acceptable ease. Guides for both groups were placed with minor but detectable deviations from the planned location (P = .01), but deviations were not significantly different between groups. Fracture reduction resulted in similar minor but detectable morphological differences from the intact tibiae (P = .01). In both groups, fracture reduction and alignment were within clinically acceptable parameters for fracture stabilization by means of minimally invasive plate osteosynthesis.
Virtual surgical planning and fabrication of patient-specific 3-D–printed pin guides have the potential to facilitate fracture reduction and alignment during use of minimally invasive plate osteosynthesis for fracture stabilization.
