Prosthetic Hip Joint Infection of Digestive Origin, Diagnosis of a Rare but Serious Condition: A Case Report.

Introduction: Prosthetic joint infection (PJI) is a relatively infrequent occurrence; however, it always poses a significant risk to the patient's functional outcome. The origin of PJI is often a topic of debate. In this case, we present a PJI that resulted from a digestive fistula passing through an iliopsoas abscess, which can be regarded as an unusual consequence of rare conditions.

Touch® double mobility arthroplasty for trapeziometacarpal osteoarthritis: outcomes for 92 prostheses.

Trapeziometacarpal prostheses have been used in the treatment of first carpometacarpal joint osteoarthritis for many years. No studies have demonstrated statistical superiority over gold-standard trapeziectomy, but they have been proved to enable shorter convalescence, better pain relief and faster functional recovery. The aims of the present study were to report functional results in a large cohort treated with the Touch® new-generation dual mobility trapeziometacarpal prosthesis, with comparison to results in the literature.

Uncommon observation of bifocal giant subchondral cysts in the hip: diagnostic role of CT arthrography and MRI, with pathological correlation.

Subchondral cysts (or geodes) are common in osteoarthritis (OA), usually in association with other typical signs, i.e., joint space narrowing, subchondral bone sclerosis, and osteophytosis.
