Osteoid Osteoma of the Quadrilateral plate of acetabulum: A case report on an unusual cause of hip pain

Osteoid Osteomas are uncommon and painful benign bone tumors, according to the author. Osteoid Osteomas are common in the limbs, with Proximal femur/Hi hip area and Tibial diaphysis being the most typical locations. Osteid osteoma patients are extremely unusual in literature, and no cases have been published or reported in literature. Case Summary 2013 The case presented u2013 A young female with long-standing hip pain was diagnosed with osteoid osteoma in an extremely rare region of her pelvic bone. The lesion was discovered to be in the Quadrilateral plate/Medial wall of acetabulum after careful examination of the imaging. For the past two years of follow-up, the patient reported complete relief of her symptoms and has been disease-free. Conclusion: - A high degree of clinical suspicion is required to keep osteoid osteoma as a differential diagnosis in a patient with the relevant signs.

Evaluation results of using GAP II acetabular cage for acetabulum in revision total hip arthroplasty

One of the most difficult procedures in hip arthroplasty is Acetabular revision arthroplasty with significant bone loss. The graft augmentation prosthesis has been developed specifically as an implant for revision acetabular reconstruction. In a revision of acetabular cage in total hip arthroplasty, we evaluated the use of a GAP II acetabular cage. According to the American Academy of Orthopedic Surgeons' database, we included all patients in class 3a and 3b of Paprosky bone loss classification and type III bone loss in class 3a and 3b. Our results revealed that using a GAP II acetabular cage in the reconstruction of acetabulum in hip revision surgery is highly recommended.

Cryptococcal osteomyelitis of the left acetabulum: A case report.

In this case, we describe a case of cryptococcal osteomyelitis in a Chinese patient with persistent hepatitis B. Case Report The case of a female with left acetabulum pain and limited mobility was reviewed retrospectively by a researcher with fever during the outbreak who presented to the Fifth Affiliated Hospital of Zunyi Medical University. Upon imaging, we found osteolytic bone decay in the left acetabular tissue, as well as absces formation.

Insufficiency fracture of the supra-acetabulum that required differentiation from a pathological fracture secondary to a malignant bone tumor: a case report.

Case study The hospitalization of a 74-year-old Japanese man was admitted to the hospital due to right hip joint pain. In the immediate region of the T2-weighted picture, a linear, low-signal region and its immediate region were visible at the same location in the T1-weighted image, as well as a high signal region and a linear low-signal region and a wide sign zone. The bone density in the lumbar spine was 66%, and blood analysis revealed an increase in alkaline phosphatase and total type I procollagen N-terminal propeptide. By biopsy results, this case was identified as an insufficiency fracture of the supra-acetabulum in a male patient with primary osteoporosis. This is expected to be bone marrow edema related to the stress fracture, and we believe this to be a useful finding that may help distinguish a stress fracture from a pathological fracture secondary to a malignant lesion.
