Fracture of the polyethylene tibial post in the posterior-stabilized total knee prosthesis: arthrographic and CT arthrographic diagnosis.

Skeletal Radiol 2019 Feb 7. Epub 2019 Feb 7.

Department of Medical Imaging, Chi Mei Medical Center, Yongkang, No. 901, Zhonghua Rd Yongkang District, Tainan City, 71004, Taiwan.

Fracture of the polyethylene tibial post in the posterior-stabilized total knee prosthesis is often delayed in diagnosis due to its nonspecific symptoms and the radiolucent characteristic of polyethylene on conventional radiography. Therefore, the diagnosis is always established by arthroscopy. Notwithstanding recent advances in imaging modalities, we are presently aware of only two related case reports on MRI and even no reports about arthrographic or CT-arthrographic diagnosis of fractured tibial post.

Magnetic resonance imaging of subchondral insufficiency fractures of the lower limb.

Skeletal Radiol 2019 Jan 31. Epub 2019 Jan 31.

Royal National Orthopaedic Hospital NHS Trust, Stanmore, UK.

Subchondral insufficiency fracture (SIF) is a non-traumatic condition that has historically been associated with elderly, osteoporotic women and patients with systemic conditions. There has been much work done to determine the pathogenesis of SIF, which has previously been regarded as idiopathic, rapid-progressive osteoarthritis or osteonecrosis of the hip, spontaneous osteonecrosis of the knee (SONK), osteochondral defect (OCD) of the talus and adult-onset Freiberg infraction of the metatarsal head. Early diagnosis and management are crucial to prevent subchondral collapse, secondary osteonecrosis and early-onset osteoarthritis. Read More

High-resolution ultrasound of the fascia lata iliac crest attachment: anatomy, pathology, and image-guided treatment.

Skeletal Radiol 2019 Jan 7. Epub 2019 Jan 7.

Northwestern Memorial Hospital/Northwestern University, Chicago, IL, 606011, USA.

Pathology of the fascia lata attachment at the iliac crest (FLAIC) is an under-recognized and often misdiagnosed cause of lateral hip pain. The fascia lata has a broad attachment at the lateral iliac crest with contributions from the tensor fascia lata muscle, the iliotibial band, and the gluteal aponeurosis. The FLAIC is susceptible to overuse injuries, acute traumatic injuries, and degeneration. Read More

Posterior dislocation of the long head biceps tendon: a case report, specific radiographic finding, and review of the literature.

Skeletal Radiol 2019 Jan 5. Epub 2019 Jan 5.

Department of Radiology, University of Illinois at Chicago, 1740 W Taylor Street Rm 2483, (MC 931), Chicago, IL, 60612, USA.

Posterior dislocation of the long head of the biceps tendon uncommonly occurs with traumatic shoulder injury. The diagnosis is almost always associated with anterior shoulder dislocation which often cannot be reduced. We present a case of traumatic posterior dislocation of the long head of the biceps tendon with no reported history of shoulder dislocation, but instead a rare and specific radiographic finding.

Giant cell reparative granuloma of the scapula: report of a case and literature review.

Skeletal Radiol 2019 Jan 4. Epub 2019 Jan 4.

Department of Orthopedics and Orthopedic Oncology, University of Padova, Via Giustiniani 3, Padova, Italy.

Giant cell reparative granulomas (GCRGs) are non-neoplastic inflammatory lesions, usually observed in the maxilla, mandible or small bones of the hands and feet. These lesions present a wide range of morphology and the misinterpretation with other giant cell lesions can often occur. We report the case of a 47-year-old woman with GCRG in the left scapula, presenting some uncommon features: the location (scapula) and age at presentation, the lack of underlying bone disease such as Paget's disease or fibrous dysplasia, the large aggressive expansile aspect of the lesion.

Adhesive capsulitis: review of imaging findings, pathophysiology, clinical presentation, and treatment options.

Skeletal Radiol 2019 Jan 3. Epub 2019 Jan 3.

Keck School of Medicine, University of Southern California, Los Angeles, CA, 90033, USA.

Adhesive capsulitis, commonly referred to as "frozen shoulder," is a debilitating condition characterized by progressive pain and limited range of motion about the glenohumeral joint. It is a condition that typically affects middle-aged women, with some evidence for an association with endocrinological, rheumatological, and autoimmune disease states. Management tends to be conservative, as most cases resolve spontaneously, although a subset of patients progress to permanent disability. Read More

Magnetic resonance imaging appearances of the capsulo-osseous layer of the iliotibial band and femoral attachments of the iliotibial band in the normal and pivot-shift ACL injured knee.

Skeletal Radiol 2018 Dec 28. Epub 2018 Dec 28.

Department of Clinical Imaging, Imperial College Healthcare NHS Trust, Praed Street, London, W2 1NY, UK.

Background: Biomechanical evidence suggests that the anterolateral structures of the knee may be important restraints against anterolateral rotatory instability (ALRI) in the setting of anterior cruciate ligament (ACL) injury.

Objective: To describe the anatomy and presence of injury of the capsule-osseous layer of the iliotibial band (CITB), the iliotibial band, and its deep distal femoral attachments in patients with a 'normal' knee (no pivot-shift bone marrow edema (BME) pattern) and patients with a pivot-shift BME pattern indicative of a pivot-shift injury associated with ACL tears.

Methods: Group 1: 20 consecutive patients with no MRI evidence of pivot-shift injury and group 2: 20 consecutive patients with a pivot-shift BME pattern on MRI were identified. Read More
