Tear-drop fracture of the axis are rare. It is characterized by a fracture of the anterior-inferior corner of the C2 body. The mechanism is usually in extension which is different from the tear-drop of lower cervical spine. We report two cases of adults who sustained a road traffic accident. They did not have any neurological deficit. The diagnosis was made on radiological examination. They both were treated conservatively with rigid immobilization and recovered well. Tear-drop fracture of the axis are usually stable. Imagery is the key of the diagnosis. Neurological deficit is rare. Conservative management usually give good outcome for non-complicated cases.
Abstractcontext: Prosthetic joint infection due to Mycobacterium tuberculosis (MTB) with no previous history of pulmonary or extra pulmonary tuberculosis is a rare complication.Aims: To report the case of a patient with tuberculous mycobacterial prosthetic hip infection, 14 years after surgery for post traumatic osteoarthritis, with no previous history of tuberculosis.methods: A 46-year-old male presented with acetabular loosening of a cemented total hip arthroplasty with normal biologic parameters. A one stage revision surgery was planned. Intraoperative findings suggested mycobacterial tuberculous infection with presence of periacetabular yellowish rice-shaped granules.results: A one-stage prosthesis exchange was performed; Culture on Löwenstein-Jensen medium grew MTB days after inoculation and histological examination confirmed tuberculous infection. Patient was treated with antituberculous agents for 12 months with optimal clinical and biological response and no prosthetic loosening signs at two year follow up.conclusions: Total hip arthroplasty loosening due to mycobacterium tuberculosis is a rare entity, which should be considered even when no inflammatory signs are shown. Discovery of yellowish riceshaped granules is suggestive of periprosthetic tuberculosis. Management of prosthetic joint infection due to M.tuberculosis must involve both medical and surgical therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
