Introduction: A novel angle-stable nail (I-Loc) was recently designed, in part to address acute perioperative instability documented with standard veterinary nails. While experimental studies demonstrated biomechanical efficacy, clinical evaluation of the I-Loc is lacking. Our objective was to describe the use of the 6, 7 and 8-mm I-Loc nails and provide clinically relevant recommendations.

Materials and Methods: Medical records of patients with traumatic femoral, tibial and humeral fractures treated with an I-Loc were reviewed. Data collected included affected bone, fracture pattern, body weight in relation to nail size; surgical technique, number of missed bolts and complications.

Results: One hundred fractures affected the femur (64%), tibia (28%) and humerus (8%); most were diaphyseal (81%) and complex (59%). The 6, 7 and 8-mm nails were used in 18, 36 and 56 patients weighing an average of 24.6, 29.7, 37.9 kg, respectively. Missed bolts (6%) were successfully reoriented intraoperatively in all but two cases (final missed rate 1.3%). All complications (10%) occurred in tibial fractures and required revision surgery in 3 cases. Complete or on going follow up, available in 80 cases showed appropriate bone healing and function in all cases. Twenty cases were lost to follow-up.

Discussion/Conclusion: This study suggests that diaphyseal, metaphyseal and juxta-articular fractures can be successfully treated using an I-Loc. Additionally, the rate of missed cannulations and complications were substantially lower than that reported for standard nails. Our results also suggest that 6, 7 and 8-mm nails can be safely recommended for dogs with mean body weights of 25, 30 and 38 kg, respectively.
