Atlantoaxial subluxation caused by Brucella infection is rarely seen in children. ⋯ Atlantoaxial dislocation and instability develops secondarily to paravertebral abscesses, only rarely. Like brucellosis of childhood, granulomatous infectious diseases rarely cause atlantoaxial subluxation or dislocation. Torticollis and neck pains should be taken seriously for the purpose of early diagnosis of patients at risk in endemic regions. Stabilization and fusion should be performed when instability is detected, and these patients should be assessed with both pediatric infectious diseases and neurosurgery clinics. Our case is the first one in the literature in which atlantoaxial instability developed due to Brucella infection and stabilization was performed.

Anterolateral ligament injury has a synergic impact on the anterolateral rotatory laxity in acute anterior cruciate ligament-injured knees.
To investigate the prevalence of the anterolateral ligament (ALL) injuries and its role in rotatory laxity in acute anterior cruciate ligament (ACL)-injured knees. ⋯ Retrospective prognostic study, Level IV.

Anatomic Risk Factors for Focal Cartilage Lesions in the Patella and Trochlea: A Case-Control Study.
Focal cartilage lesions in the patellofemoral (PF) joint are common. Several studies correlated PF risk factors with PF instability, anterior knee pain, and PF arthritis; however, there is a lack of evidence correlating those factors to PF focal cartilage lesions. ⋯ PF anatomic abnormalities are significantly more common in patients with full-thickness PF cartilage lesions. Trochlear dysplasia, patella alta, and excessive lateral patellar tilt are the most common correlated factors, especially in patellar lesions.

Role of Hip Injury and Giving Way in Pain Exacerbation in Hip Osteoarthritis: An Internet-Based Case-Crossover Study.
To evaluate the association between hip injury/giving way and hip pain exacerbations in patients with symptomatic hip osteoarthritis (OA). ⋯ Hip injury and episodes of the hip giving way were significantly related to pain exacerbation in patients with symptomatic hip OA. Methods to prevent exposure to injury may help to reduce the burden of pain in patients with hip OA.

Recurrence of glenohumeral joint instability after primary traumatic anterior instability is not rare, and bipolar bone loss is one of the most critical factors for recurrent instability, but the development process of bipolar bone defects is still unclear. ⋯ In most shoulders with recurrent instability, a Hill-Sachs lesion developed first, followed by a glenoid defect, leading to bipolar bone loss. Off-track Hill-Sachs lesions were detected only after recurrence.
