In De Moya 2023 et al., on femoral physeal/neck fracture repair, which factor was most associated with the development of complications following FGPP?
š Key Findings
- FGPP (fluoroscopic-guided percutaneous pinning) resulted in successful healing in 10/13 fractures, with good limb function.
- Complications occurred in 5 of 11 cases, including intra-articular implants, malunion, implant failure/nonunion, and implant migration.
- Cases with delayed surgery (>15 days) or radiographic remodeling were more likely to experience major complications.
- Most fractures (10/13) were classified as Salter-Harris type I with mild displacement.
- Median surgical time was 60 minutes, and no conversions to open surgery were needed.
- Postoperative femoral neck resorption was minimal, suggesting possible benefits of the minimally invasive approach for preserving vascular supply.
- One intra-articular pin led to progressive joint disease and required femoral head ostectomy.
- FGPP appears best suited for acute, minimally displaced fractures in young dogs (<8 months) with planned elective explant to avoid growth disturbance.

In Turner 2025 et al., on TPA changes after SH-1/2 fracture repair, what surgical feature may contribute to the dynamic reduction in TPA over time?
š Key Findings
- TPA decreased significantly from preoperative to follow-up (mean 5.89°; p < 0.001), and from immediate postoperative to follow-up (mean 2.2°; p = 0.018)
- Use of tension band in addition to K-wires did not significantly improve TPA reduction compared to K-wires alone
- Cranial K-wire positioning may attenuate growth at the cranial tibial physis, allowing relative caudal growth to reduce TPA over time
- Dynamic TPA reduction may reduce risk of cranial cruciate ligament rupture even when initial TPA is high
- Small breeds (e.g., French Bulldogs) were overrepresented; further research is needed in larger breeds with more growth potential
- Surgical reduction is difficult, but perfect alignment may not be essential if TPA reduces postoperatively
- Radiographic TPA measurement was reliably performed with low interobserver variability
- K-wire removal at 3ā8 weeks may facilitate continued growth in growing dogs

In Carrera 2024 et al., what was the observed long-term effect on aLDFA and tibial torsion at 1-year postoperatively?
š Key Findings Summary
- 5 juvenile dogs (mean age 7.2 months) with grade IIIāIV MPL were treated surgically.
- Most had femoral varus + external tibial torsion; some had shallow trochlear grooves.
- Distal femoral osteotomy was performed in 4/5 dogs; Tibial tuberosity transposition (TTT) in 3/5; Sulcoplasty in 2/5.
- Mean time to weight bearing: 9.8 ± 5.5 days; healing: 55 ± 24 days
- No reluxations, and final radiographic values for aLDFA and torsion were maintained at 1 year.
- One complication due to domestic trauma, not surgical failure.
- Early surgery appeared to preserve alignment and prevent deformity progression.

In Forzisi 2025 et al., on femoral growth post-THR, what was the relationship between age at surgery and femoral length difference?
š Key Findings
Population: 24 dogs (<8.5 months) undergoing unilateral cementless THR.
Growth Impact:
- Operated femurs showed ~11.5% less trochanteric growth than controls (p = .002).
- No significant difference in femoral diaphyseal + epiphyseal length (p = .712) or femur overall (p = .465).
Cortical Width:
- Increased significantly at 10 mm distal to trochanter (4.6% increase, p = .037) and at 50% femoral length (8.5% increase, p = .030).
Clinical relevance: Despite measurable changes, no clinically significant impairment to femoral length occurred.
Effect Sizes:
- Moderate negative for trochanteric growth.
- Moderate positive for proximal femoral width.

In Isono 2025 et al., on tibial malalignment in MPL, which statistical trend was observed in toy poodles with grade 3 MPL?
š Key Findings
- Proximal Tibia Metatarsal Angle (PTMTA) was significantly increased in dogs with grade 3 and 4 MPL, making it a useful marker for severity.
- PTMTA strongly correlated with Tibial Torsion Angle (TTA) (r = 0.733) and Crural Rotation Angle (CRA) (r = 0.643), integrating multiple morphological deformities.
- Grade 4 MPL cases showed significant internal tibial torsion, increased mMPTA, and decreased MDTT/PTWāindicating both rotation and medial displacement.
- DTMTA was significantly more negative in grade 4, indicating a consistent pattern of internal foot rotation with disease severity.
- PTMTA can be visually assessed during palpation, offering preoperative utility without CT.
- Among toy poodles, PTMTA showed significant differences even between grades 3 and normal, suggesting breed-specific severity patterns.
- Corrective osteotomy may need to address tibial as well as femoral deformities in severe MPL cases with high PTMTA.
- Younger dogs with grade 4 MPL had more severe deformities, possibly due to early onset or developmental progression.
