Ertao Jia, Junqing Zhu, Wenhui Huang, Xiaoguang Chen, Juan Li
The aim of this study was to discuss the diagnostic value of dual-energy computed tomography (DECT) in patients with gout during different disease phases. Two hundred twenty-one patients (136 with gout and 85 with other arthritic diseases) were recruited to the study. Arthrosis pain was evaluated in all patients by DECT scans. We calculated the sensitivity and specificity of DECT for the diagnosis of gout, including the first onset period, less than 24 months period, and more than 24 months period. We then investigated the related risk factors of urate crystals volume in the foot...

REVIEW
Anish R Kadakia, Armen S Kelikian, Mauricio Barbosa, Milap S Patel
Medial column instability is a primary deforming force in the setting of pes planovalgus deformity. Consideration for medial column stabilization only after correction of the hindfoot deformity may result in creating a rigid hindfoot, compromising clinical outcomes. Careful analysis of the lateral radiograph to determine whether the deformity is secondary to the medial column or true peritalar subluxation may allow superior outcomes. Iatrogenic creation of an excessively rigid medial column may lead to significant instability of the remaining joints in the short term and arthrosis in the long term...

BACKGROUND AND AIMS: Many kinds of insoles and pads are commonly used as a conservative treatment of metatarsalgia. However, earlier studies of insole treatment provide contradictory results, and the natural progression of metatarsalgia is still unknown. The aims of this study were to (1) determine whether simple custom-made metatarsal pad insoles reduce pain and improve functional ability, (2) find out patients' satisfaction with padding treatment, and (3) investigate predisposing factors for metatarsalgia...

The histopathological synovitis score evaluates the immunological and inflammatory changes of synovitis in a graduated manner generally customary for diagnostic histopathological scores. The score results from semiquantitative evaluation of the width of the synovial surface cell layer, the cell density of the stroma and the density of the inflammatory infiltration into 4 semiquantitative levels (normal 0, mild 1, moderate 2, severe 3). The addition of these values results in a final score of 0-9 out of 9. On the basis of this summation the condition is divided into low-grade synovitis and high-grade synovitis: A synovitis score of 1 to≤4 is called low-grade synovitis (arthrosis-associated/OA synovitis, posttraumatic synovitis, meniscopathy-associated synovitis and synovitis with haemochromatosis)...

Trapeziometacarpal joint prosthesis revision has been widely reported, mainly due to loosening of the trapezium cup. Our hypothesis is that current prostheses do not sufficiently respect the kinematics of this joint. CT scan acquisitions enabled us to determine the position of the first metacarpal relative to the trapezium in three different characteristic postures, in subjects in different stages of arthrosis. A CAD model of a current prosthesis was inserted into the numerical 3D model of the joint under the different postures...

The treatment of complex elbow dislocation fractures is a challenge to both the treating surgeon as well as to the patient due to the complex bony and soft tissue anatomy of the joint. In order to establish an expedient treatment algorithm, all osseous and ligamentous injuries need to be thoroughly assessed. Furthermore, a detailed knowledge of the joint-stabilizing structures, practicable surgical approaches as well as the possible techniques for fracture fixation and/or arthroplasty are essential to facilitate early rehabilitation of the elbow and avoid injury-related complications...

INTRODUCTION: Subtalar dislocation is an uncommon lesion in traumatology chiefly when it concerns the lateral form. Surgical treatment is required when a fracture is related or the dislocation is irreducible. Even well treated, these dislocations progress unavoidably to subtalar arthrosis, which stays well tolerated. CASE REPORT: A 46-year-old male with irreducible lateral subtalar dislocation caused sustentaculum tali incarceration confirmed on computed tomography (CT)...

Kienbock's disease, or avascular necrosis of the lunate, is a progressive disease ultimately resulting in end-stage arthrosis of the wrist. Various surgical treatments are available for different Lichtman stages of disease. We review the surgical options and indications, expected radiologic post-operative appearance, as well as detail potential surgical complications, as they relate to Kienbock's disease.

INTRODUCTION: Both the overall shape of the calcaneus and anatomical reduction of joint congruity are important prognostic factors. However, there is a significant lack of biomechanical data supporting the clinical importance of calcaneus height, length and heel width. The objective of this study was to determine the effects of abnormal calcaneus morphology on ankle-hindfoot biomechanics. HYPOTHESIS: The normal biomechanics of the ankle-hindfoot would be severely disrupted by the abnormal calcaneus morphology...

Kimberly A Waller, Ling X Zhang, Gregory D Jay
Deficiency of PRG4 (lubricin), the boundary lubricant in mammalian joints, contributes to increased joint friction accompanied by superficial and upper intermediate zone chondrocyte caspase-3 activation, as shown in lubricin-null (Prg4(-/-)) mice. Caspase-3 activity appears to be reversible upon the restitution of Prg4 either endogenously in vivo, in a gene trap mouse, or as an applied lubricant in vitro. In this study we show that intra-articular injection of human PRG4 in vivo in Prg4(-/-) mice prevented caspase-3 activation in superficial zone chondrocytes and was associated with a modest decrease in whole joint friction measured ex vivo using a joint pendulum method...

OBJECTIVE: Osteoblastoma (OB) is a painful, rare, benign bone tumour usually observed in young populations, and this condition involves the spine in up to one-third of cases. We sought to focus on the minimally invasive treatment of spinal OB with radiofrequency ablation (RFA) under computed tomography (CT) guidance. When performed near the spinal cord, surgery can lead to instability of the spine, sometimes requiring additional interventions to stabilise the segments involved, and can cause the precocious onset of arthrosis or other degenerative diseases...

BACKGROUND: Pigmented villonodular synovitis (PVNS) is a rare, benign proliferation of the synovium, commonly affecting the knee. Arthroplasty can successfully manage arthrosis in this population; however, outcome data is limited. The purpose of this study was to investigate the oncologic and functional outcome of patients undergoing total knee arthroplasty (TKA) in the setting of PVNS. METHODS: 48 patients were identified at our institution with histologically confirmed PVNS that subsequently received TKA...
