Efficacy of Adjuvant Application of Platelet-Rich Plasma After Needle Aspiration of Calcific Deposits for the Treatment of Rotator Cuff Calcific Tendinitis: A Double-Blinded, Randomized Controlled Trial With 2-Year Follow-up.

Background: Needle aspiration of calcific deposits (NACD) is a frequently used treatment for rotator cuff calcific tendinitis (RCCT). However, a substantial number of patients experience recurrent or persisting shoulder symptoms after NACD.

Purpose: To compare the effects of adjuvant application of platelet-rich plasma (PRP) after NACD (NACP+PRP) with those of conventional NACD with corticosteroids (NACD+corticosteroids) on pain, shoulder function, and quality of life (QoL).

Prognostic factors for the outcome of needle aspiration of calcific deposits for rotator cuff calcific tendinitis.

Objective: To identify prognostic factors for the effectiveness of needle aspiration of calcific deposits (NACD) for rotator cuff calcific tendinitis (RCCT) METHODS: One hundred forty-nine patients with symptomatic RCCT were included in a prospective cohort study. Pain (VAS), shoulder function (SST and DASH), and quality of life (EQ-5D) were assessed at baseline and at 3, 6, and 12 months post-NACD. Univariate analyses (independent t tests or Mann-Whitney U tests depending on the distribution of data) were performed to build a multivariable linear regression model.

Needle aspiration of calcific deposits (NACD) for calcific tendinitis is safe and effective: Six months follow-up of clinical results and complications in a series of 431 patients.

Background: Although needle aspiration of calcific deposits (NACD) has proven to be an effective treatment for calcific tendinitis of the rotator cuff (CTRC) in patients who are resistant to conservative treatment, little is known about the effectiveness of NACD in terms of complete relief of symptoms and the effectiveness of repeated NACD procedures. Furthermore, analyses of complications of the procedure in large series are scarce.

Methods: 431 consecutive patients with symptomatic CTRC treated by NACD were included in this retrospective cohort study.

Model-based roentgen stereophotogrammetric analysis of the surface replacement trapeziometacarpal total joint arthroplasty.

Unlabelled: The primary aim of this clinical and radiostereometric study was to study the migration pattern of the surface replacement trapeziometacarpal joint prosthesis (SRTMC, Avanta, San Diego, CA). The secondary aims were to assess patient-related outcomes and prosthesis survival 5 years after surgery. Ten patients received the prosthesis.

Feasibility of model-based Roentgen Stereophotogrammetric Analysis to evaluate early migration of the trapeziometacarpal joint prosthesis.

Background: The purpose of this study was to determine the feasibility of Roentgen Stereophotogrammetric Analysis (RSA) in total joint arthroplasty of the trapeziometacarpal (TMC) joint of the thumb.

Methods: In five cadaveric hands the TMC-joint was replaced by the Surface Replacement Trapeziometacarpal prosthesis (SR™ TMC prosthesis; Avanta, San Diego, CA) and tantalum beads of 0.8 mm were implanted for RSA.
