The aim of this study was to assess arthritis of the basal joint of the thumb quantitatively using bone single-photon emission CT/CT (SPECT/CT) and evaluate its relationship with patients’ pain and function. We retrospectively reviewed 30 patients (53 hands) with symptomatic basal joint arthritis of the thumb between April 2019 and March 2020. Visual analogue scale (VAS) scores for pain, grip strength, and pinch power of both hands and Patient-Rated Wrist/Hand Evaluation (PRWHE) scores were recorded for all patients. Basal joint arthritis was classified according to the modified Eaton-Glickel stage using routine radiographs and the CT scans of SPECT/CT, respectively. The maximum standardized uptake value (SUVmax) from SPECT/CT was measured in the four peritrapezial joints and the highest uptake was used for analysis.Aims
Methods
Porous coated cups have a low modulus of elasticity that enhances press-fit and a surface that promotes osseointegration as well as permitting modularity. Monoblock ceramic acetabular cups represent a subtype of uncemented cup permitting the use of large femoral heads. The aim of this study was to compare the short-term clinical and radiographic performances of both cups. This was a prospective RCT of 86 unilateral THA patients (M: 40, F: 48; mean age: 59.5 ± 10.6) randomized to either a porous-coated, modular metal-on-polyethylene (MoP) acetabular component (pore size 250µm, 45% mean volume porosity)(n=46) or a hydroxyapatite (HA) and titanium-coated monoblock shell with ceramic-on-ceramic(CoC) bearing (pore size 300µm, 48% mean volume porosity & 80nm HA coating thickness)(n=42). All sockets were under-reamed by 1 mm. Two-year radiographs and patient-reported outcomes (PROMs) were available.Introduction
