Abstract Purpose To evaluate the diagnostic accuracy of SPECT/CT arthrography in patients with suspected aseptic prosthesis loosening following hip and knee arthroplasty. Methods A retrospective review 63 arthrogram studies (36 knees 27 hips) between February 1, 2013, July 2018, was conducted. All underwent clinical radiologic evaluation as part their assessment for persistent pain The detectio...

BACKGROUND A study was designed to quantify the extent of porous osseointegration at the prosthesis-bone interface in the Prestige LP prosthesis containing a plasma-sprayed titanium coating. METHODS Using an anterior surgical approach, cervical disc arthroplasty was performed in 8 mature male goats at the C3-C4 segment, followed by implantation of the Prestige LP prosthesis. The vertebral spe...

Based on the thermo elasticity, using finite element method to analyze the stress of femur-prosthesis system when the hip joint has been replaced, a reference for the selection of prosthesis material is presented after discussing the thermo physical property of material which has an effect on the stress of femur-prosthesis system. We assume that prosthesis, bone cement and femur are linear elas...

The reverse shoulder prosthesis is designed for the treatment of glenohumeral arthritis with irreparable cuff arthropathy. Although it has given good short term results the prosthesis is not free of complications. In this case report we describe an implant-related complication.

Numerical studies were performed to investigate bone cement polymerization, temperature history and thermal osteonecrosis in cemented hip replacements with finite element methods. In this paper, the effects of pre-cooling and pre-heating of the prosthesis and/or the cement prior to implantation were simulated. It was found that the cement polymerization initiated near the bone-cement interface ...

Introduction Total elbow design has evolved dramatically over the last century. Prior to 1947, resection and interposition arthroplasty were the primary surgical procedures for the treatment of severe posttraumatic deformity, trauma, and rheumatoid arthritis. In 1947, surgeons began performing partial elbow replacements of the distal part of the humerus and proximal part of the ulna as well as ...

Hip resurfacing is an established treatment for osteoarthritis in young active patients. Failure modes include femoral neck fracture and prosthesis loosening, which may be associated with medium-term bone adaptation, including femoral neck narrowing and densification around the prosthesis stem. Finite element modelling was used to indicate the effects of prosthesis sizing and positioning on the...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2013-201090 DESCRIPTION A 78-year-old woman with diabetes, hypertension and severe omarthrosis, had a left total shoulder arthroplasty in May 2010. In September 2010, the patient developed axillar abscess, without fever or pain, which was incised. Propionibacterium ac...

Vibration analysis can be used as a more sensitive alternative to conventional techniques for the detection of loosening of total hip replacement (THR) components. The vibration modes of the human femur and of selected THR prosthetic stems were studied by experimental modal analysis using a CADA-X system and by finite element simulation using MARC/Mentat software. Two hypotheses were formulated...
