Over the last 2 decades, the incidence of prosthetic shoulder replacements has increased considerably, leading to a rising number of complications and reoperations. In this article, we review how SPECT/CT can be of significant clinical value for shoulder surgeons. Bone SPECT/CT can provide the correct diagnosis for different types of mechanical complications: glenoiditis after hemiarthroplasty, glenoidal loosening after total shoulder arthroplasty, and scapular notching after reverse shoulder arthroplasty. Various nuclear medicine methods are available for detecting prosthesis infection. In our experience, labeled white blood cell scintigraphy combined with bone marrow scintigraphy is the reference standard. FDG-PET may be useful in case of discordance between the white blood cell scan and the clinical context and complementary test results.

The humeral head is the second most common anatomical site of osteonecrosis after the femoral head. Studies have reported satisfactory clinical outcomes after shoulder arthroplasty to treat osteonecrosis of the humeral head (ONHH). However, there are concerns regarding implant longevity in relatively young patients.

Objective: We present long-term results for the Pyrocardan®, a pyrocarbon trapeziometacarpal interposition implant used for the treatment of osteoarthritis of the thumb.
Methods: Between March 2009 and May 2013, 199 arthroplasties were performed in a single hand center, in 184 patients by 6 hand surgeons. 107 implants were followed up for a mean 137 months (range, 120 to 168 months).

Objectives: Rheumatoid arthritis often leads to debilitating damage in the elbow joint, which may require total elbow arthroplasty (TEA). The Kudo TEA is one of the unlinked type prostheses with reportedly favorable outcomes. However, there is limited information available regarding its long-term performance.

Background: Proximal humerus fractures (PHF) are common with approximately 30% requiring surgical intervention. This ranges from open reduction internal fixation (ORIF) to shoulder arthroplasty (including hemiarthroplasty, total shoulder arthroplasty (TSA), reverse total shoulder arthroplasty (RTSA)). The aim of this study was to assess trends in operative interventions for PHF in an Australian population.

Objective: This study evaluated the effect of three-dimensional (3D) volumetric humeral canal fill ratios (VFR) of reverse shoulder arthroplasty (RSA) short and standard stems on biomechanical stability and bone deformations in the proximal humerus.
Methods: Forty cadaveric shoulder specimens were analyzed in a clinical computed tomography (CT) scanner allowing for segmentation of the humeral canal to calculate volumetric measures which were verified postoperatively with plain radiographs. Virtual implant positioning allowed for group assignment (VFR < 0.
