Suspension arthroplasty versus interposition arthroplasty in the treatment of trapeziometacarpal osteoarthritis: a clinical and magnetic resonance imaging study

AbstractIntroductionBiological arthroplasties are the most used surgical techniques, for the treatment of trapeziometacarpal osteoarthritis; all of them provide the reconstruction of trapeziometacarpal joint by a tendon graft. The aim of the study is to compare two surgical techniques: interposition arthroplasty and suspension arthroplasty at 12-month follow-up in order to evaluate the clinical and radiographic results.MethodsSixty-seven patients surgically treated for basal thumb osteoarthritis were divided into two groups: 36 patients, (8 M; 27 F) (39 hands), treated with interposition arthroplasty are included in group A and 31 patients, (6 M; 25 F) (34 hands), treated with suspension are included in group B. Both groups were radiographically evaluated with X-ray and MRI at 12  months and clinically evaluated with DASH score, VAS, Grind test, hand grip tests, Kapandji test and ROM before surgery and at final follow-up.ResultsAt final follow-up about Kapandji test, in group A, 31 hands (79.4%) presented Kapandji score of 10 and eight hands (20.6%), a Kapandji score of 8. In group B, six hands (17.6%) reported a Kapandji score of 8 and 28 patients (82.4%), a Kapandji score of 10 (p

r F Abstract Primary osteoarthritis of the shoulder represents a destructive joint disease with associated synovitis, which in the first line seems to be genetically determined. Clinically, patients suffer from shoulder pain with progressive impairment of both active and passive range of motion. The diagnostics include a clinical examination, imaging by native radiography and magnetic resonance imaging (MRI) for assessment of the rotator cuff. Current classification systems consider the formation of humeral osteophytes, glenoid morphology and loss of humeral sphericity. Non-surgical measures include, apa...

AbstractObjectiveThe aim of this study was to investigate cross-sectional associations between serum levels of IL-8 and the above outcomes in patients with knee osteoarthritis (OA).MethodsA total of 160 subjects with clinical knee OA were included. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score and Lequesne index were used to assess the joint symptom. Magnetic resonance imaging was used to measure knee structural abnormalities including infrapatellar fat pad (IPFP) signal intensity alternation. Knee radiographic OA was assessed by radiography using the Kellgren-Lawrence (K-L) grading system. E...

AbstractDegenerative osteoarthropathy is one of the leading causes of the pain and disability from musculoskeletal disease in the adult population. Magnetic resonance imaging (MRI) allows optimal visualization of all tissues involved in degenerative osteoarthritis disease process, mainly the articular cartilage. In addition to qualitative and semiquantitative morphologic assessment, several MRI-based advanced techniques have been developed to allow characterization and quantification of the biochemical cartilage composition. These include quantitative analysis and several compositional techniques (T1 and T2 relaxometry mea...

Abstract The aim of this study is to investigate clinical and radiographic outcomes of a biomimetic scaffold for the treatment of osteochondral knee lesions in patients with early OA. Study population was represented by 26 patients with a mean age of 44 years affected by early OA. Inclusion criteria were two episodes of knee pain for more than 10 days in the last year, Kellgren-Lawrence OA grade 0 or I or II, and arthroscopic findings of cartilage defects. Nineteen patients had a previous surgery, 11 of which were revision surgeries of osteochondral unit. All patients were treated with a biomimetic scaffold with a...

Depending on the nature of the tissue connecting the bones, the abnormality is a syndesmosis, synchondrosis, or synostosis. Although the coalition exists at birth, synostosis usually develops only late during growth. Talo-calcaneal and calcaneo-navicular coalitions account for over...

AbstractPurposeIncreased femoral antetorsion influences patellofemoral joint kinematics. The aim of this study was to retrospectively evaluate the clinical outcome after derotational osteotomies and combined procedures in patients with patellofemoral instability.MethodsAll patients with derotational osteotomies and combined procedures in patients with patellofemoral instability and increased femoral antetorsion performed between 2007 and 2016 were retrospectively analyzed. Exclusion criteria were open growth plates, posttraumatic deformities, and a follow-up period less than 12  months. Simple radiography and magnetic...

AbstractPurpose of ReviewOsteoarthritis (OA) is a major cause of pain and disability worldwide. There is, however, a relatively poor correlation between the severity of OA based on plain radiograph changes and symptoms. In this review, we consider the mechanisms of pain in OA.Recent FindingsIt is now widely recognised that OA is a disease of the whole joint. Data from large observational studies which have used magnetic resonance imaging (MRI) suggest that pain in OA is associated with a number of structural factors including the presence of bone marrow lesions (BMLs) and also synovitis. There is evidence also of alteratio...
