“…While an ex vivo mechanical study of pancarpal arthrodesis (PCA) constructs provided evidence that the use of a cast significantly reduced plate strain, the strain magnitude was low and considered unlikely to be clinically significant. 11 This ex vivo finding would appear to be supported by the results of a retrospective study on PCA in which it was concluded that external coaptation had no measurable benefit. 12 From a mechanical perspective in PTA, medial plating allows "edge" loading of the implant, and, compared to dorsal plating, increases the dorsoplantar bending stiffness of the construct.…”

“…External coaptation has been advocated to provide adjunctive stability after arthrodesis with internal fixation, 18,19 although the effectiveness of coaptation in reducing loading of the implants remains unclear. In an ex vivo study on PCA, Woods et al 11 found that, although the application of a cast to the distal portion of the limb significantly reduced strain in a 2.7/3.5-mm hybrid PCA plate, the magnitude of the measured strain was low. This provided evidence that fatigue damage was unlikely to accumulate as a result of this type of loading and that external coaptation may not be required to prevent fatigue failure of the plate.…”

Objective To report long‐term outcomes of dogs treated with pantarsal arthrodesis (PTA) with medial plate fixation without external coaptation. Study design Retrospective case series. Animals Client‐owned dogs (n = 30). Methods Medical records of dogs that had undergone a PTA with a medially applied plate without adjunctive rigid external coaptation were reviewed. Data collected included signalment, complications, and assessment of function at last physical examination. Follow‐up information was obtained by phone conversations with owners. Complications were classified as minor, major II, major I, and catastrophic. Results Thirty‐six PTA were performed in 30 dogs. Recorded complications included eight (22.2%) minor complications, 11 (30.6%) major II complications and 11 (30.6%) major I complications. One (2.8%) dog required amputation because of catastrophic complication. Owners provided follow‐up for 26 dogs at a median duration of 1215 days (range, 325‐3495) after surgery. The outcome was reported as full function in 12 dogs and acceptable function in 14 dogs, with no owners reporting unacceptable function. The owner of the dog in which amputation was required was not contacted. Incorrect contact details prevented owner follow‐up in the other three dogs, but all had acceptable function at last veterinary follow up. Conclusion Dogs treated with PTA by medially applied plate had a high incidence of complications requiring surgical or medical management, although full or acceptable function was achieved in 29 of 30 dogs. Clinical significance: Pantarsal arthrodesis offers a predictably good medium to long‐term outcome in spite of a high risk of complications.

Objective The aim of this study was to evaluate outcomes and complications of dogs that had pancarpal arthrodesis (PCA) using a titanium hybrid advanced locking plate system (ALPS) and stainless steel hybrid dynamic compression plate (HDCP). Study Design Retrospective observational study. Methods Medical records (2007–2020) were reviewed for cases that had PCA performed using ALPS or HDCP. Implant characteristics including metacarpal coverage (MCov), metacarpal width occupied by screw diameter percentage and carpal arthrodesis angle (CAA), complications and outcomes were recorded. Results Pancarpal arthrodesis was performed with ALPS on 15 limbs from 12 dogs, and HDCP on 14 limbs from 11dogs. Median follow-up time was 1,157 days (range: 62–1,902 days) for ALPS group and 340 days (range: 43–1,465 days) for HDCP. Median MCov for ALPS group was 74% (range: 60–87.5%) compared with 56.5% (range: 49.7–91.3%) for HDCP (p = 0.001). There was no difference in CAA and metacarpal width to screw diameter percentage between ALPS and HDCP group. Major and minor complications and surgical site infection rates were not statistically different between the two groups. Plate fracture occurred in 2/15 ALPS PCA and screw loosening occurred in 4/14 HDCP PCA. Full function was achieved in 8/12 and 8/11 of ALPS and HDCP cases, respectively, which was not statistically different (p = 0.76). Conclusion The use of ALPS offers comparable performance to HDCP for PCA
