Introduction Scapular neck fractures are mostly considered as instable fractures that result in severe non-weightbearing lameness and dysfunction of the front limb recommending surgical therapy. Material and methods 4 cats with scapular neck fractures were reviewed clinically and radiographically throughout the postoperative period. At the time of long-term re-evaluation between 6 and 44 months after surgery, additional goniometry and force-plate analysis were performed in the 4 clinical patients and in 4 cats serving as a control group. Results Clinical examination revealed no lameness in 3 of the patients whereas cat no. 3 showed a grade 1 lameness. All 4 scapular neck fractures were radiographically healed with minimal degenerative joint disease. In the patient group, mean range of motion (ROM) calculated was 94 degrees in cat 1, 100 degrees in cat 2, 40 degrees in cat 3 and 83.3 degrees in cat 4. In the control group, mean ROM ranged from 140 to 143.3 degrees. Statistical analysis resulted in significant differences between clinical patients and control group (p = 0.02). In the patient group, normalized vertical force ranged from 3.1 to 4.2 N/kg BM. In the control group, data ranged from 4.1 to 5.8 N/kg BM. No significant difference between the frontlegs was calculated in these cats. Comparison of the operated frontleg to the left frontleg of the control cats revealed significantly higher values for the controls (p = 0.04). Clinical relevance and conclusion Goniometry and force plate analysis are practicable methods to detect differences between orthopedically injured and sound cats.
