Purpose: To analyze the risk of tooth loss and complications in periodontal ligament (PDL) healing following extrusive and lateral luxation in the permanent dentition.
Materials And Methods: Eighty-two permanent teeth (78 patients) with extrusive luxation and 179 teeth (149 patients) with lateral luxation were included in the study. All teeth were examined according to a standardized protocol including clinical, photographic, and radiographic registration. Follow-up controls were performed at regular intervals (3, 6 weeks, 6 months, 1, 5, and 10 years).
Statistics: The risk of repair-related resorption (surface resorption), infection-related resorption (inflammatory resorption), ankylosis-related resorption (replacement resorption), marginal bone loss, and tooth loss was analyzed with the Kaplan-Meier method. Differences among subgroups were analyzed with log-rank test and Cox regression.
Results: The risk of periodontal healing complications was estimated after 3 years. Extrusive luxation: For immature root development, infection-related resorption was 2.4% (95% confidence interval (CI): 0-6.9%). For mature root development, repair-related resorption was 15.6% (95% CI: 4.4-26.7%), infection-related resorption was 5.1% (95% CI: 0-11.7%), and marginal bone loss was 17.5% (95% CI: 6.2-28.8%). No teeth showed ankylosis-related resorption, and no teeth were lost in the observation period. Lateral luxation: For immature root development, repair-related resorption was 2.1% (95% CI: 0-6.1%), infection-related resorption was 2.1% (95% CI: 0-6.1%). For mature root development, repair-related resorption was 29.5% (95% CI: 20.5-38.5%), infection-related resorption was 2.6% (95% CI: 0-6.4%), ankylosis-related resorption was 0.8% (95% CI: 0-2.3%), marginal bone loss was 6.9% (95% CI: 2.2-11.6%).
Conclusion: The risk of severe periodontal healing complications in teeth with extrusive and lateral luxation injuries is generally low. Marginal bone loss and repair-related resorption occurred significantly more often in teeth with mature rather than immature root development. Marginal bone loss was associated with injuries involving multiple teeth.

Abnormal trochlear morphology is one of the most important factors for patellar luxation occurrence in dogs, yet no studies have investigated its prevalence in the general population. This retrospective computed tomography study was designed to evaluate the trochlear groove morphology in four small dog breeds and the prevalence of trochlear dysplasia types according to Déjour's classification depending on the breed, sex, and medial patellar luxation (MPL) presence and grade. A total of 174 joints (68 healthy, 96 grade II MPL, and 10 grade III MPL) from Mini-Pinschers, Yorkshire Terriers, Pomeranians, and Chihuahuas were included in the study.

Objective: To assess the influence of conservative or invasive treatments on the appearance of sequelae in permanent successor teeth (SPT) after injuries in the support tissues of anterior deciduous teeth (ISTDT).
Methods: This cohort study accompanied 52 children with ISTDT up to the complete eruption of the permanent successor to investigate the presence or not of SPT. Trauma was clinically evaluated according to the International Association for Dental Traumatology.
Synovial lipomatosis is an uncommon, intra-articular, fat-containing, proliferative lesion with unknown etiology that is rarely reported in dogs. A retrospective study spanning 13 years was conducted to search for cases of canine synovial lipomatosis. Among 188 synovial biopsies of major diarthrodial joints (ie, shoulder, elbow, carpus, hip, stifle, and tarsus) from 186 dogs, 4 cases (2.

The present case report is an observational study with a literature review. This case is significant because the injury is rare regarding location and clinical manifestation. A middle-aged male patient sustained a fracture at the acromial end of the clavicle with lateral fragment dislocation after falling from a bicycle.

Objectives: The aim of this study was to assess the complication rates and long-term outcomes, as well as to refine case selection criteria for cats undergoing trochlear ridge augmentation (TRA) using an ultra-high molecular weight polyethylene implant (UHMWPEI) for the treatment of patellar luxation (PL).
Methods: The clinical records from two referral veterinary hospitals were searched for cases that fitted defined inclusion criteria. A short-term assessment was based on examination and radiography at 8 weeks postoperatively.
