🔍 Key Findings

• 42% of dogs (33/78) treated with Arthrex 3.5 mm STS during TPLO developed radiographic TCTF
• TCTFs occurred exclusively distal to the osteotomy
• 14% of screws (36/250) distal to the osteotomy were associated with TCTFs
• 6% of dogs with TCTFs developed major complications (e.g., complete tibial fracture requiring surgical revision)
• Angulation of cortical STS screws, especially in the distal plate holes, was a key contributor to complications
• Locking screws were also involved, but cortical screws angled improperly were overrepresented in serious outcomes
• Revision recommendations included preemptive fixation for large TCTFs or angulated screw placements
• Use of non-self-tapping screws (NSTS) previously showed a <1% TCTF rate, supporting higher risk with STS

🔍 Key Findings

140 laparoscopic surgeons surveyed; 37% reported at least one musculoskeletal disorder.
Women had significantly higher odds of reporting WRMD (OR = 2.59, p = .011).
Smaller glove size significantly associated with WRMD (p = .001), shoulder tendonitis (p = .01), and neck strain (p = .001).
Most common injuries: Neck strain (35%), shoulder tendonitis (31%).
WRMD was associated with greater difficulty using:

• Rotating cup biopsy forceps (p < .001)
• Vessel sealing device and endo stapler (especially in those with shoulder injuries)

No significant association with surgeon age, dominant hand, height, weight, or case volume.

🔍 Key Findings Summary

• 20 shoulders from 11 medium-to-large breed dogs evaluated
• Lateral portals used: middle arthroscopic, caudal instrument, cranial egress
• Musculotendinous lesions unavoidable, but small (18G needle); seen in deltoideus (90%), infraspinatus, teres minor, etc.
• Neurovascular safety:
  • Caudal portal was closest to axillary artery/nerve branches (as close as 7 mm)
  • Only 2/20 shoulders (10%) had omobrachial vein penetrated
• Cartilage injuries (IACI) occurred in 65%, primarily minor linear defects; use of guarded cannulas and distractors suggested for minimization
• Supports overall safety of lateral shoulder arthroscopy with portal placement awareness

🔍 Key Findings

• All dogs developed progressive osteoarthritis (OA) after surgical debridement of proximal humeral OC.
• Ipsilateral muscle atrophy and reduced shoulder range of motion were common, particularly in unilaterally affected dogs.
• Arthroscopically, lesions showed incomplete cartilage infilling even years after surgery, averaging only ~37% infilling.
• Synovitis was present in all joints, with moderate-to-severe hypertrophy and vascularity scores.
• CT identified OC lesions as deeper and wider than radiography, and all affected joints had more advanced OA than contralateral limbs (P = .001 radiograph, P = .005 CT).
• Kinetic gait analysis showed no significant differences in peak vertical force or impulse, but a subtle 4.4% asymmetric load reduction on the operated limb.
• Median LOAD score was 6, indicating mild owner-perceived disability despite measurable clinical and imaging abnormalities.
• Cartilage infilling was incomplete in all cases, with no lesion exceeding 60% restoration, raising questions about the healing potential of debridement alone.

🔍 Key Findings

• Locked facet injuries in dogs involved unilateral dorsal displacement of the cranial articular process of the caudal vertebra, most commonly at C5/6 or C6/7.
• All affected dogs were small/toy breeds, typically following trauma (most often attacks by larger dogs).
• Neurologic severity ranged from ambulatory tetraparesis to tetraplegia, often with thoracic limb deficits more severe than pelvic limbs — suggesting a central cord syndrome-like pattern.
• CT and MRI revealed axial rotation, subluxation, and articular process displacement; MRI showed T2 hyperintensity, nerve root impingement, and soft tissue changes.
• Surgical treatment included ventral fixation with screws, pins, and PMMA, and one case required dorsal facetectomy for reduction.
• Medical management, including external coaptation or rest, also resulted in functional recovery in select cases.
• All dogs with follow-up data (8/8) had functional recovery, with nonambulatory dogs regaining ambulation in a median of 4 weeks.
• No consistent differences in outcome were observed between surgical and nonsurgical management, suggesting locked facets may be biomechanically stable.

🔍 Key Findings

• This anatomical study mapped fascial planes of the canine hindlimb and pelvis to aid superficial tumor resection.
• Type I fascia (discrete sheets) was suitable for deep margins in fascia lata, lateral crus, and gluteal regions.
• Areas with poor or absent fascia included the ischiorectal fossa, femoral triangle, stifle extensor mechanism, and pes.
• Type IV fascia associated with periosteum (e.g., patella, tibial tuberosity) required partial ostectomy for inclusion in surgical margins.
• Nerves at risk during deep dissection included obturator, superficial peroneal, and tibial nerves, particularly in regions with weak fascia.
• In males, bulbospongiosus muscle could act as a fascial plane but dissection was challenging and potentially hemorrhagic.
• In females, constrictor vulvae/vestibulae muscles were tightly associated with mucosa, limiting clean resection options.
• Distal hindlimb resections often lacked a usable fascial plane, suggesting that amputation or adjuvant therapy may be more appropriate.

🔍 Key Findings

• 48% of the intra-articular biceps tendon was visible at a standing angle; this increased to 63% in flexion (p = 0.0003).
• 58% of the medial glenohumeral ligament's cranial border was within view.
• 20% of the subscapularis tendon was visualized via the standard lateral arthroscopic approach.
• Visibility was assessed using tattoo ink markers and confirmed via dissection in cadavers.
• Limitations of standard lateral portals may lead to underdiagnosis of deeper or distal pathology in these structures.

🔍 Key Findings

• Two-pin fixation had significantly greater strength (639 N) than single-pin fixation (426 N) in TTAF models (p = .003).
• Stiffness was also higher with two-pin constructs (72 N/mm vs 57 N/mm); statistically significant (p = .029).
• Both fixation types withstood loads greater than quadriceps force in dogs at a walk (240 N), indicating clinical viability.
• Failure was most commonly due to pin bending or pullout (82%), with fewer cases of ligament tearing or epiphyseal fracture.
• K-wire insertion angle (KWIA) did not significantly differ between fixation types (p = .13).
• Single larger pins delivered ~68% of the strength and ~83% of the stiffness of two smaller vertically aligned pins.
• Clinical implication: Two vertically aligned pins are biomechanically superior for TTAF fixation in canine models.
• Study used mature cadavers, which may underestimate loads and stiffness compared to immature clinical cases.

🔍 Key Findings

• Supracutaneous locking plates (SLPs) were successfully used to manage 33 diaphyseal fractures (radial–ulnar and tibial) in 30 cats and dogs.
• Median fracture healing time was 50.5 days (range: 27–88), with most patients regaining limb use within days postoperatively.
• CT-based metrics (callus area, HU, and 3D bone volume) increased significantly during healing (p < 0.05), validating CT as a quantitative tool for assessing healing.
• Complications were minimal: minor in 15/33 (e.g., screw tract discharge, edema), and major in 3/33 (e.g., implant failure, delayed union, nonunion).
• Minimally invasive osteosynthesis required longer surgery times than closed reduction (p < 0.05), but both techniques were viable.
• SLPs enabled successful bilateral fracture management without inter-plate interference due to their compact design.
• Screw orientation challenges were noted in cats, especially with cranial application to the radius due to narrow anatomy.
• Polyaxial locking screws were used safely and did not dislodge, allowing for angular insertion (≤10°) to avoid neurovascular structures.
