AI Article Synopsis
- Dislocation of the thumb's carpometacarpal (CMC) joint is uncommon, but chronic cases can cause serious disability; surgical treatment has evolved to consider both the anterior oblique and dorsoradial ligaments for better recovery.
- A 59-year-old male underwent open reduction and repair of a chronically dislocated thumb CMC joint, successfully stabilizing it with pin fixation and reinforcing the dorsoradial ligament.
- After 12 weeks, the patient experienced no significant activity limitations, indicating that this surgical method is effective for managing chronic CMC joint dislocations.
Article Abstract
Dislocation of the thumb carpometacarpal (CMC) joint is a rare injury; chronic CMC dislocation can lead to significant disability. Traditionally, surgical intervention has focused on the reconstruction of the anterior oblique ligament, though more recently there has been more focus on the dorsoradial ligament. Consideration of both ligaments during CMC joint reconstruction is important to optimize functional outcomes. A 59-year-old male presented with a subacute/chronically dislocated CMC joint of the thumb. Open reduction with pin fixation and dorsoradial ligament repair and augmentation was chosen to restore the stability of the joint. Joint reduction without subluxation was successfully maintained. By 12 weeks postoperatively, there were no remaining major restrictions to activity. Repair of the dorsoradial ligament with augmentation and pinning is a viable approach for surgical management of subacute/chronic dislocation of the thumb CMC joint.

Long-Term Outcome Over 15 Years of Prosthesis for Thumb Carpometacarpal Joint Arthritis: A Case Series.
Cureus

Orthopaedic Surgery, Toho University Ohashi Medical Center, Tokyo, JPN.
This report presents the long-term (over 15 years) results of four Japanese patients who underwent total joint replacement for thumb carpometacarpal (CMC) joint arthritis. Four patients (mean age 60.5 years) underwent prosthesis replacement for thumb CMC joint arthritis with AVANTA(TM) (Small Bone Innovations, Morrisville, PA, USA) implants between 2001 and 2004, with a mean follow-up of 20 years and seven months.

Background: Thumb carpometacarpal (CMC) joint osteoarthritis is among the most common degenerative hand diseases. Thumb CMC arthroplasty, or trapeziectomy with or without tendon augmentation, is the most frequently performed surgical treatment and has a strong safety profile. Though adverse outcomes are infrequent, the ability to predict risk for complications has substantial clinical benefits.

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.

Purpose: Arthrodesis and ligament reconstruction and tendon interposition (LRTI) are commonly performed procedures for treatment of thumb carpometacarpal (CMC) osteoarthritis. Although LRTI is the most common surgical treatment, CMC arthrodesis has been performed because of its reported advantages. This systematic review and meta-analysis compared the differences between CMC arthrodesis and LRTI to better inform surgeons and patients when they are making treatment decisions.

Green tea seed oil (GTSO; Camellia sinensis) is rich in bioactive compounds and has great potential for preventing intestinal inflammation. Conversely, high-fat diets have been shown to promote or aggravate gastrointestinal inflammation, and the bioactive ingredients of GTSO face difficulty passing through the gastrointestinal tract while remaining intact. This study employed whey protein isolate (WPI) and sodium carboxymethyl cellulose (CMC-Na) to prepare a GTSO-loaded double-layer emulsion.
