AI Article Synopsis
- Osteoarthritis in the thumb base is common, especially in middle-aged and older women, leading to significant disability, prompting the need for effective treatments beyond traditional methods like steroid injections.
- A controlled trial is set to compare the effectiveness of high-concentration platelet-rich plasma (PRP) injections against saline (placebo) for pain relief and functional improvement in patients with thumb base osteoarthritis.
- The study will evaluate pain and functional outcomes over a year, aiming to determine if PRP provides significant benefits compared to the placebo, filling a gap in current evidence about its efficacy.
Article Abstract
Background: Osteoarthritis in the thumb base (trapeziometacarpal joint, CMC-1 joint) is prevalent, particularly among middle-aged and elderly women, causing significant disability. Conservative treatments, including steroid injections, have been questioned for their efficacy, prompting exploration into alternative therapies such as platelet-rich plasma (PRP) injections. This randomized, double-blinded, controlled trial aims to evaluate the effectiveness of high-concentration PRP (platelet-rich plasma) injection compared to saline (placebo) in reducing pain and disability in patients with thumb base osteoarthritis.
Methods: Patients meeting inclusion criteria will be randomized and blinded, with injections administered under sterile conditions and radiological guidance. With a planned sample size of 90 patients recruited from the Department of Hand Surgery at Södersjukhuset, Stockholm, the study will assess pain relief and functional improvement at 3, 6, and 12 months post-injection. The primary outcome measure is pain on load (numerical rating scale) at 6 months, with secondary outcomes including patient-reported outcomes, key pinch, grip strength, abduction of the thumb, and time to intervention within 1 year. Statistical analyses will employ non-parametric tests, chi-square tests, and generalized estimating equations to compare outcomes between the PRP and placebo groups.
Discussion: The study aims to provide evidence regarding the efficacy of high-concentration PRP injections for thumb base osteoarthritis. If PRP proves superior to saline in reducing pain and improving function, it could offer a promising alternative treatment. Conversely, if PRP does not demonstrate significant benefits over placebo, its use for this condition is not justified. This study seeks to address the current gap in evidence regarding the efficacy of PRP injections for thumb base osteoarthritis.
Trial Registration: The study has been approved by the Swedish Ethical Review Authority (2023-06860-01 and 2024-01238-02) and is registered on ClinicalTrials.gov (NCT06193499) 2024-01-04.

Dorsoradial ligament reconstruction versus imbrication for restoring trapeziometacarpal joint stability: a comparative biomechanical study.
Sci Rep

Department of Orthopedic Surgery, Yonsei University College of Medicine, Seoul, South Korea.
The unique saddle articulation of the trapeziometacarpal joint allows for a wide range of motion necessary for routine function of the thumb. Inherently unstable characteristics of the joint can lead painful instability. In this study, we modified a surgical dorsal ligament reconstruction technique for restoring trapeziometacarpal joint stability.

Background: Bennett's fracture, a fracture-dislocation of the base of the first metacarpal, poses significant challenges due to the unique biomechanics of the thumb's carpometacarpal (CMC) joint. Effective management is critical to restoring thumb function and preventing long-term complications such as arthritis and instability.
Objective: This article provides a comprehensive overview of Bennett's fracture, including its mechanism of injury, diagnostic considerations, and management strategies, with a focus on conservative and surgical options.

Objective: Our primary objectives are to assess whether intraarticular corticosteroid injections are superior to saline injections with regards to thumb base pain after 4 weeks, and to compare the efficacy of steroid injections, saline injections, and an occupational therapy intervention on thumb base pain after 12 weeks in people with painful inflammatory osteoarthritis (OA) of the first carpometacarpal (CMC-1) joint.
Design: In this three-armed, double-blind, randomized multicenter trial, 354 participants with painful inflammatory CMC-1 OA from six Norwegian hospitals are recruited. Participants are randomized 1:1:1 to intraarticular steroid or saline injections in the CMC-1 joint or a multimodal occupational therapy intervention.
