We hypothesized that PSG is more accurate (i.e., positioning and orientation closer to the optimal trajectory) and safer (reduced incidence of joint violation) than the AD.Methods: A total of seven pairs of forelimbs were allocated to PSG and AD groups. After CT scanning, the optimal TCS orientation was planned in silico by a surgical specialist, and guides were printed. Using the PSG or AD, a 2.5-mm drill hole was drilled from medial to lateral across the humeral condyle. The positioning of the \"planned\" and \"achieved\" drill holes was defined on postoperative CT. The accuracy of TCS positioning and the risk of joint penetration were then calculated for the two groups.Results: Positioning of the entry and exit holes was significantly more accurate in the PSG group. Differences in screw angulation were not significantly different between groups. Despite the presence of an outlier (caused by incomplete seating of the PSG against the bone), 7 out of 7 screws positioned with PSG were \"safe,\" while 3 out of 7 from the AD group would have violated the joint.Conclusion: Our data confirm the technical superiority of PSG over the AD for placement of a TCS in the humeral condyle.","PeriodicalId":51204,"journal":{"name":"Veterinary and Comparative Orthopaedics and Traumatology","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143400721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Collected data included signalment, racing history, and laterality of tarsal injury. Central tarsal bone fractures were characterized using a previously described grading system, and concomitant tarsal injuries were recorded.Results: Of 67 central tarsal bone fractures, 59 showed moderate to severe comminution. Six fractures were dorsal slab fractures, one was a combined dorsal and medial slab fracture, and one was a luxation. Consistent with the findings of prior studies, the majority of central tarsal bone fractures affected the right limb (58/67 limbs). The most common concomitant tarsal injuries were fractures of the fourth tarsal bone (30/67 limbs), fractures of the calcaneus (25/67 limbs), and proximal intertarsal instability or luxation (6/67 limbs).Conclusion: CT reveals a substantially higher number of highly comminuted fractures than have been reported in prior studies that characterized central tarsal bone fractures using orthogonal radiography. Concurrent injury to other tarsal structures is a common finding and is an accurate predictor of severe comminution of the central tarsal bone.","PeriodicalId":51204,"journal":{"name":"Veterinary and Comparative Orthopaedics and Traumatology","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143400718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Surgical planning utilized CAD-based techniques, and 3D-printed guides were created for precise osteotomies and implant placement. Follow-ups included radiographic assessments, re-examinations, and owner-reported outcomes.Results: Four feline cases with distinct shoulder issues were successfully treated using PSG. Postoperative management, radiographic evaluations, and long-term follow-ups revealed positive outcomes in terms of limb function and patient activity. The study demonstrates the potential of PSG in achieving accurate humeroscapular alignment in feline shoulder arthrodesis.Clinical significance: This case series highlights the clinical significance of PSG in enhancing the precision of humeroscapular alignment during feline shoulder arthrodesis.

Signalment, body weight, fracture aetiology, fracture location and configuration, radius diameter, plate-bone ratio, repair method, clinical and radiographic outcomes, complications, and time to last follow-up were recorded.Results: Thirty fractures in 28 dogs were included. Median body weight was 2.4 kg (range 1.3-5.5 kg). The mean length of the proximal segment relative to the total length of the radius was 67% (range 33-93%). The mean diameter of the radius at its isthmus was 4.9 mm (range 3.1-6.1 mm). The mean plate-bone ratio was 64% (range 48-89%). Radiographic union was documented in 29/30 fractures at a median of 8 weeks postoperatively.

Medical records from 2017 to 2022 were reviewed to identify dogs with SH-1 or SH-2 fractures of the proximal tibial physis that had undergone surgical repair with Kirschner wires (K-wires), with or without a tibial tuberosity tension band. The TPA of the affected limb was measured by four investigators on radiographs taken prior to surgery, immediately postoperatively and at 4-8 weeks follow-up, with the average values recorded.Results: A total of 32 dogs, 22 fractures repaired with K-wires and a tension band, and 10 with K-wires only. There was a mean decrease in TPA from injury to first reevaluation of 5.89 degrees (p < 0.001) and from immediately postoperatively to first reevaluation of 2.2 degrees (p = 0.018); however, no significant decrease in TPA was observed when comparing fractures repaired with or without a tension band.Conclusion: The TPA of dogs with SH-1 and SH-2 fractures of the proximal tibial physis decreased in the reevaluation interim following repair with K-wires with or without a tension band. Despite initial imperfect reduction, the risk of cranial cruciate ligament rupture may not be increased, potentially reducing the need for additional surgery if high TPA is observed postoperatively. This study was overrepresented by small breeds, and future studies on large and giant breeds with extended follow-up would be indicated.","PeriodicalId":51204,"journal":{"name":"Veterinary and Comparative Orthopaedics and Traumatology","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143015871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patient history, fracture etiology, preoperative diagnostics, and intraoperative findings were documented. Postoperative performance data were collected using Thoroughbred Racing database or a telephone questionnaire.Results: All cases had wounds with concurrent synovial sepsis of the tarsocrural joint. Standard weight-bearing radiographs were performed preoperatively (n = 15), but most (n = 13) failed to identify PMTR pathology. When acquired (n = 8), flexed radiographs (including a uniquely described flexed plantaroproximolateral dorsodistomedial Pl30Pr45Lat-DoDiM oblique) identified PMTR lesions. PMTR TOCF were removed during the initial surgery (n = 15) or subsequent (n = 3) arthroscopy, performed due to unresolved synovial sepsis. Fifteen out of 16 horses with >6-month follow-up resumed full exercise.Conclusion: Flexed tarsal radiographs should be performed as part of a standard protocol for traumatic wounds involving the medial tarsus.

Two peripheral locking screws were placed in each segment, with the remaining screw holes left unfilled. Three strain gauges were glued to each LCP at anticipated regions of maximum strain. Constructs underwent cyclic uniaxial loading at a rate of 20 mm/min to 400 N in three different configurations (Configuration 1: no LHI, Configuration 2: 3 LHI, Configuration 3: 9 LHI). LHI were tightened to 4 Nm of torque. A data acquisition system was used to collect implant strain during testing. Construct stiffness and deformation were recorded by the biomechanical testing machine.Results: Maximum implant strain was recorded at the central screw hole directly over the simulated fracture gap in all configurations (Mdn 1,837.3 µε [interquartile range: 1,805.1-1,862.0]). There was no difference in implant peak-to-peak strain with addition of LHI at all three gauges (Gauge 1 [p = 0.847], Gauge 2 [p = 0.847], Gauge 3 [p = 0.311]).
