In Payne 2024 et al., on HIF propagation pattern, which finding was significantly associated with higher %HIF?
🔍 Key Findings Summary
- HIF typically originates 57° caudal to the supratrochlear foramen and propagates cranially in a segmental pattern.
- %HIF correlated significantly with both fissure depth and length:
- %DHIF increased linearly (r = 0.989, p < 0.001)
- %LHIF followed a sigmoidal relationship with %HIF (p < 0.001)
- Higher %HIF was significantly associated with:
- Clinical lameness (p = 0.004)
- Distal shift in the fissure center (CHIF)
- Implant complications in 5/17 elbows treated with transcondylar screws

In De Moya 2025 et al., on antebrachial deformity correction, what was the mean total radial lengthening achieved after distraction osteogenesis?
🔍 Key Findings
- CESF with distraction osteogenesis restored elbow congruity and normalized aLDRA in skeletally immature dogs with PCDRP.
- Radial head subluxation was eliminated in all dogs, and elbow incongruity reduced significantly (from 6.1 mm to 0.3 mm, p <.01).
- Mean radial lengthening of 22.6 mm (∼11% of normal length) was achieved, but only 80% of recorded distraction translated to length gain.
- Major complications occurred in 2/12 dogs: one with permanent carpal contracture, one with radial fracture at wire tract.
- Minor complications (e.g., carpal pain, restricted extension, synostosis, pin tract issues) were noted in 10/12 dogs but generally resolved.
- Owner surveys (8/12 dogs) reported good to excellent long-term function, even up to 6 years post-op.
- Radial valgus deformities were moderate (mean 15°) and less severe than deformities from ulnar physeal closure.
- Surgical strategy included staged distraction, with radial or combined radius/ulna distraction guided by fluoroscopy and adjusted per case.

In Picavet 2026 et al., on sesamoid displacement radiography, what was the reported prevalence of popliteal sesamoid displacement in dogs with cranial cruciate ligament disease on preoperative 90° flexion radiographs?
🔍 Key Findings
- Popliteal sesamoid displacement (PSD) was identified in 14.4% of dogs with CCLD on preoperative 90° flexion radiographs, indicating it is an uncommon but notable radiographic finding.
- Dogs with PSD had significantly greater cranial tibial subluxation (CTS) preoperatively compared with dogs without PSD.
- Popliteal sesamoid reduction occurred in 100% of cases after TPLO, suggesting that proper TPLO mechanics restore normal sesamoid position.
- Postoperative CTS persisted in all dogs that had preoperative CTS (50.3%), although the magnitude of subluxation was significantly reduced after TPLO.
- Osteotomy positioning (centered vs distally centered) did not significantly influence postoperative CTS, indicating residual translation is not strongly affected by osteotomy placement.
- Postoperative tibial plateau angle (TPA) showed a weak negative correlation with residual CTS, suggesting lower TPAs may slightly reduce postoperative tibial translation.
- PSD appears to be associated with more pronounced stifle instability prior to surgery, serving as a radiographic indicator of more severe CCLD biomechanics.
- Radiographic evaluation of popliteal sesamoid reduction may provide an additional objective indicator of residual cranio-caudal instability following TPLO.

In Petchell 2025 et al., on CORA-based CCWO, which parameter was defined preoperatively to enable CORA-based planning?
🔍 Key Findings
- The CORA-based cranial closing wedge ostectomy (CCWOCORA) consistently achieved the target postoperative TPA of 5° across all tibial morphologies.
- CCWOCORA produced significantly less variability in postoperative TPA compared to other methods (TPA range: 5.00–5.00°; p < .001).
- Mechanical axis advancement (MAA) was precisely controlled at 3° in CCWOCORA, leading to greater surgical predictability.
- Other techniques (e.g., CCWOTPA, CCWOTPA–5, CCWOISO) showed greater variance in TPA, MAA, and tibial length.
- In small-breed dogs, increasing the MAA from 3° to 5° did not affect TPA outcomes, but increased proximal bone stock, improving feasibility.
- Wedge angles and tibial length changes varied by method, but CCWOCORA maintained length better than TPA-based methods.
- The technique allows preoperative planning of both desired MAA and TPA, enhancing predictability and customization.
- CORA methodology enables precise geometric correction and alignment of mechanical axes, reducing reliance on trial-and-error alignment.
