Danielski et al: Influence of oblique proximal ulnar osteotomy on humeral intracondylar fissures in 35 spaniel breed dogs
Veterinary Surgery 2, 2024

🔍 Key Findings Summary

  • Sample: 51 elbows from 35 spaniel dogs
  • Healing Rate: Subjective healing (complete or partial) in 80.3% of elbows; complete in 54.9%
  • Objective HU analysis: Mean HU increased from 640 (pre-op) to 835 (follow-up) (p = .001)
  • Age Effect: Dogs <14 months showed the greatest HU increase (+384 HU) and had wider fissures with less sclerosis
  • Complications:
    • Major: 5 dogs (6 limbs); 4 related to fissure healing (7.8%), 2 related to PUO healing (3.9%)
    • Minor: 3 cases (5.8%) due to IM pin migration
  • Sclerosis: Older dogs had more humeral condyle sclerosis, possibly limiting healing
  • PUO Effectiveness: Confirmed cranio-proximal displacement of anconeal process; aimed to relieve humero-anconeal incongruity
  • Control Comparison: Avoids complications associated with transcondylar screw (infection, breakage)

Multiple Choice Questions on this study

In Danielski 2024 et al., on PUO effect on HIF, what percentage of elbows demonstrated subjective partial or complete healing on follow-up CT?

A. 60.1%
B. 70.5%
C. 80.3%
D. 85.7%
E. 92.4%

Answer: 80.3%

Explanation: Subjective healing was observed in 41 out of 51 elbows, amounting to 80.3% of the cases.
In Danielski 2024 et al., on PUO effect on HIF, what was one proposed biomechanical outcome of PUO regarding the anconeal process?

A. It migrated caudally into the olecranon fossa
B. It rotated laterally into the condyle
C. It displaced cranio-proximally toward the supratrochlear foramen
D. It impinged more on the medial condyle
E. It flattened against the ulnar notch

Answer: It displaced cranio-proximally toward the supratrochlear foramen

Explanation: The study confirmed cranio-proximal displacement of the anconeal process following PUO.
In Danielski 2024 et al., on PUO effect on HIF, which group showed the largest increase in HU at the fissure site postoperatively?

A. Dogs aged 0–14 months
B. Dogs aged 15–96 months
C. Dogs >96 months
D. Dogs weighing >20kg
E. Dogs with partial fissures

Answer: Dogs aged 0–14 months

Explanation: This age group showed an average HU increase of 384.54, indicating the highest healing response.
In Danielski 2024 et al., on PUO effect on HIF, what was the mean preoperative Hounsfield unit (HU) value of the fissure ROI on CT?

A. 480
B. 550
C. 640
D. 835
E. 920

Answer: 640

Explanation: The preoperative HU for the fissure region of interest was reported as 640.
In Danielski 2024 et al., on PUO effect on HIF, which of the following postoperative complication rates was reported for major HIF-related issues?

A. 3.1%
B. 5.9%
C. 7.8%
D. 9.2%
E. 12.4%

Answer: 7.8%

Explanation: Four out of 51 elbows experienced major complications related to fissure healing (7.8%).
