Osteoarthritis is one of the most common diseases in veterinary medicine. There are various causes for joints developing OA, with some of them being well investigated, while others are still a matter of speculation. In this retrospective study we examined the prevalence of OA in the shoulder, elbow, hip and stifle joints in a clinic population of dogs older than 8 years, which were presented mostly due to orthopaedic complaints. Dogs were included in the study if one or more of the aforementioned joints was included in the radiographs. Radiographs were reviewed by three different observers and graded by severity. Prevalence of OA was 39.2%, 57.4%, 35.9% and 36.4% for the shoulder, elbow, hip and stifle, respectively. There was no correlation between higher grades of OA and weight as well as age, but significantly higher prevalence of OA in heavier groups when grouped for weight. Sex and castration status did not affect presence of OA. As most of the examined joints were free of OA, radiographic findings suggestive of OA should not be considered normal in senescent dogs.

Anatomic total shoulder arthroplasty in the 7th decade of life demonstrates superior long-term maintenance than in older patients.
J Orthop

Department of Orthopaedic Surgery, Icahn School of Medicine at Mount Sinai, New York, NY, USA.
Background: Anatomic total shoulder arthroplasty (aTSA) is often delayed due to concerns about a more rapid loss of postoperative improvements in younger, more active patients. This retrospective study investigated the effects of patient age on activity-specific functional outcomes at a minimum of 10 years following aTSA.
Methods: A retrospective review of a shoulder arthroplasty database was performed.
Is calcification integral to enthesopathy and tendinopathy rather than a separate disease process?

Department of Surgery and Perioperative Care, Dell Medical School-The University of Texas at Austin, Austin, TX, USA.
Background: The pathophysiology of enthesopathy and tendinopathy is mucoid degeneration, which includes chondroid metaplasia. The chondroid metaplasia can be associated with calcification. Inflammation is typically absent unless calcification triggers a self-limited immune response representing acute calcific tendinitis.

Introduction: Tumoral calcinosis is a rare hereditary condition characterized by the deposition of calcium phosphate and hydroxyapatite in periarticular soft tissues. First described by Giard and Duret in 1898 and later detailed by Inclan in 1943, this condition has often been confused with other forms of periarticular calcification. Tumoral calcinosis predominantly affects young males and is typically found around major joints, such as the shoulder, elbow, hip, ankle, and wrist.

Objective: We aimed to assess the recent trends in the demographics of radial head and neck fractures and their management based on displacement.
Methods: TriNetX was queried for cases from 1 January 2017, through 31 December 2022. ICD diagnosis codes were used to define patient cohorts with radial head or neck fractures.
The lesser tuberosity C-block osteotomy for anatomical total shoulder arthroplasty has no negative impact on the volumetric ratio of the transversal force couple.

Department of Orthopaedic Surgery and Traumatology, UZ Gent, C. Heymanslaan 10, 9000 Gent, Belgium.
Background: Mobilization of the subscapularis muscle (SSC) is crucial for optimal access to the glenohumeral joint during anatomical total shoulder arthroplasty (ATSA). However, the ideal mobilization technique remains controversial. This study aimed to assess the impact of the lesser tuberosity C-block osteotomy, a modified lesser tuberosity osteotomy, on the postoperative subscapularis (SSC) volume following anatomical shoulder arthroplasty and compare it to the volume of the infraspinatus/teres minor.
