🔍 Key Findings

• 20 cats with pelvic fractures treated with SOP plates and cortical screws
• Full function reported in all patients per FMPI follow-up
• Screw loosening in 3/20 SOP cases; implant removal in 3 cats
• Median sacral index decrease at follow-up: 5.7%; mostly mild narrowing
• Complications: 5 major (3 SOP removals, 2 trochanter osteotomy issues); 20 minor
• SOP plate shown feasible even in challenging configurations; good functional outcomes

🔍 Key Findings

Incidence of BFX lateral bolt stem breakage: 2.95% (13 dogs, 14 stems)

Implant factors:

• 13/14 were BFX lateral bolt stems (sizes #5–7)
• +9 necks used in 5/11 of 17 mm heads
• 10/14 stems undersized based on radiographs
• 10/13 dogs exceeded weight limits for implanted stem size

Malalignment:

• 10/14 had varus alignment (median 3.9°)
• 8/14 had insufficient proximodistal seating

Breakage site: Proximolateral shoulder in all cases

Revision outcomes:

• 11 revised (7 CFX, 3 larger BFX, 1 collared)
• 9/10 revised dogs regained full function
• Complications: 1 rebreakage, 1 periprosthetic fracture, 1 fixation failure

Histopathology:

• Electron microscopy showed fatigue striations and incomplete bead fusion

Conclusion: Avoid small BFX lateral bolt stems if undersized or if long necks required; use weight guidelines to prevent fatigue failure.

🔍 Key Findings

• 73 elbows (52 dogs) underwent randomized medial or lateral transcondylar screw placement for HIF.
• Lateral-to-medial placement resulted in a significantly higher rate of complications (62.2%) vs medial-to-lateral (19.4%) (p = .001).
• Odds ratio for complications: 6.11 (95% CI: 2.13–17.52).
• Most common complications: seromas (n = 13), surgical site infections (n = 16).
• Implants with lower AMI/bodyweight were significantly associated with major complications (p = .037).
• Only 4 procedures (5%) required revision surgery (major type I complications), with no difference by screw direction.
• NNT = 2.3 for medial placement to prevent one complication.

🔍 Key Findings

• 97.4% of dogs returned to normal function after total hip replacement using the BFX lateral bolt.
• Mean femoral stem subsidence was 1.22 mm, with most occurring in the first month and minimal thereafter.
• Postoperative complication rate was 13.6%, with 9.2% major and 4.4% minor complications.
• Femoral fractures (3.6%) and coxofemoral luxations (3.6%) were the most common major complications.
• Increased age and higher stem size were risk factors for postoperative femoral fractures; CFI >2.0 was also associated.
• Medial calcar fractures were avoided, and fractures occurred distal to stem ingrowth zone, simplifying repairs.
• Three cases underwent prophylactic plating, all with excellent outcomes and no complications.
• Explant rate was 2.6% (5/195), with most failures involving acetabular cup rather than femoral stem.

🔍 Key Findings

From Allaith et al., 2023 – Outcomes from a multiuser canine hip replacement registry

• 2375 total hip replacements were analyzed across 1852 dogs, making this the largest multiuser canine THR dataset to date.
• Most common indications for THR were hip dysplasia (51%) and osteoarthritis (34%).
• Implants used included Kyon (46%), BioMedtrix CFX (22%), Hybrid (11%), BFX (9%), and Helica (4.5%).
• Veterinary-reported complication rate was 8.5%, while owner-reported was 23%, with moderate agreement (k=0.44).
• Most common complications: Luxation, femoral fracture, and aseptic loosening.
• BioMedtrix BFX and Helica implants had a higher risk of complications when used after femoral head and neck excision (P = .031).
• Postoperative LOAD scores significantly improved vs preoperative (21 → 11; P < .0001), supporting improved mobility.
• Owner satisfaction was high, with 88% rating outcome as very good or good.

🔍 Key Findings

• CBLO was effective for stifle stabilization in skeletally immature dogs with CrCL injuries, avoiding disruption of proximal tibial growth plates.
• Radiographic union of the osteotomy occurred in a mean of 6 weeks (range: 4–8 weeks), indicating rapid bone healing.
• Full limb function was restored in all cases by long-term follow-up (mean 23 months), including dogs with initial complications.
• Two dogs developed 19° valgus deformities due to screw interference with the proximal tibial physis; both were corrected surgically with return to function.
• One dog developed 10° recurvatum due to over-rotation of the tibial plateau, but retained full function without revision.
• CCS (countersink compression screw) caused early apophyseal closure in older dogs but had no adverse clinical effects.
• In contrast, K-wire or plate-only fixation preserved open apophysis, suggesting implant choice may influence growth.
• No meniscal injuries were observed, and all CrCL injuries were managed arthroscopically — 6 complete, 6 partial, 4 avulsions.

🔍 Key Findings Summary

• 16 dogs (18 stifles) with CrCL rupture and TPA >34° were treated using the DCTPLO
• Mean TPA correction: from 39.4° to 6.3°
• Bone union at 60 days in 17/18 stifles; remaining healed by 90 days
• Minor complications (e.g., small wedge gaps) in 2/18 stifles — no major complications
• Patellar ligament thickening seen in 16/18 stifles but no clinical signs noted
• The technique enabled safer reduction with less risk of tibial crest fracture vs. conventional TPLO

🔍 Key Findings Summary

• 89 French Bulldogs with HCF; 40.4% (36/89) had contralateral HIF
• Prophylactic transcondylar screws placed in 20/36 HIF; no complications in these
• Complication rate for HCF repair = 13.4% (6.7% minor, 6.7% major)
• Most complications occurred with Kirschner wire fixation
• Short-term outcome: Bone healing observed in all, but 14/45 had persistent intracondylar gap
• Long-term outcomes (n=27):
  • Excellent = 66.7%
  • Good = 29.6%
  • Fair = 3.7%
• Complication-free dogs significantly more likely to have excellent/good outcomes (p = 0.007)

🔍 Key Findings

• Overall closure-related complication rate was 14.1%, lower than previously reported (17–78%).
• No clinically meaningful difference in complication rate between orthopedic wire (17.4%) and suture (11.5%) closure methods.
• Dog size (≥20 kg) was the only significant risk factor associated with increased closure-related complications (p = .01).
• Type of closure (wire vs. suture) did not affect risk, even in larger dogs.
• Suture closure showed a non-significant trend toward fewer complications (mean reduction 2.3%, 95% CI: –9.1% to +4.5%).
• Most complications were mild (62%), with only 10 severe cases requiring surgical revision.
• Infection rate was low (2.7%), and not significantly different between wire and suture.
• Suture closure is a valid alternative to wire, including in large dogs, based on this large, multi-institutional study.
