This case report describes a 17-month-old Pudelpointer with recurring motor impairment localized to the left thoracic limb. A neurological exam highlighted lameness in that limb, accompanied by pre-scapular swelling. Radiographs and magnetic resonance imaging detected an osseous structure in soft tissues close to the fifth cervical vertebra, and subsequent surgery uncovered adjacent cervical spinal nerve impingement. Histology of the bony structure revealed heterotopic ossification in paravertebral muscles. Mild bone re-formation at the operating site was detected after a 2-year period, but the patient was asymptomatic. This article reports the first case of heterotopic ossification with spinal nerve entrapment in a dog and adds a new differential diagnosis to the causes of neurogenic lameness in dogs.

Purpose: To compare the long-term clinical outcomes and radiographic findings between hybrid surgery (HS) and anterior cervical discectomy and fusion (ACDF) for three-level cervical degenerative disc disease (CDDD). And the incidence, prognosis, and potential risk factors of heterotopic ossification (HO) more than 10 years after Bryan prosthesis replacement in HS has been explored.
Methods: From January 2007 to December 2014, a total of 46 patients who underwent either HS (n = 26) or ACDF (n = 20) for consecutive three-level CDDD were retrospectively analyzed.

Background: Heterotopic ossification (HO) is a common complication following hip arthroplasty that can limit hip range of motion (ROM). Oral direct factor Xa (FXa) inhibitors are commonly used anticoagulants after arthroplasty; however, they have a high risk of local bleeding and hematoma formation, which are significant triggers for HO formation. To our knowledge, there is no evidence regarding whether FXa inhibitors will increase HO incidence following hip arthroplasty.

Case: Fibrodysplasia ossificans progressiva (FOP) is a rare autosomal dominant musculoskeletal disorder with progressive heterotopic ossification within soft connective tissues causing ankyloses and unique skeletal malformations of the big toes, which represent a birth hallmark for the disease. The classic variant is c.617G>A (p.

Introduction: Complex proximal ulna fractures (including comminuted olecranon fractures and fracture-dislocations of the elbow) pose challenging management due to concomitant injuries to key stabilizers (radial head, coronoid process, and collateral ligaments). This study evaluates functional and radiographic outcomes following surgical treatment and explores the prognostic value of associated injuries, age stratification, and a new coronoid-centric classification system.
Methods: We retrospectively reviewed 43 patients with complex proximal ulna fractures treated between 2019 and 2024, with a minimum of 12 months follow-up (mean, 28 months).

Hip arthroscopy has become an increasingly common and effective surgical technique for the diagnosis and treatment of various intra-articular hip disorders. While generally considered safe and minimally invasive, the procedure is not without risks. The increasing volume and complexity of hip arthroscopies has led to a rise in reported complications, highlighting the importance of understanding potential adverse events and their management.
