Periprosthetic complications after trapeziometacarpal arthroplasty mostly require revision surgery to restore function. An unstable cup in the trapezium is typically surgically managed by trapeziectomy. This report highlights a possible alternative to maintain the implant by reconstruction of the trapezium with corticocancellous autograft.

Purpose: The purpose of this study was to compare the maximal elastic force and deformation resistance of two commonly used headless compression screw systems, a fully threaded 2.5 mm screw and a partially threaded screw of the same dimensions, in a cadaveric model of a human transverse proximal third fracture of the proximal phalanx.

Methods: Six fresh frozen cadavers were used, and the proximal phalanges of the index, long, and ring fingers of both hands were dissected.

This study compared antegrade and retrograde headless intramedullary compression screw fixation for fractures of the proximal third of the proximal phalanx. Antegrade fixation showed superior stability, provided more rigid fixation and preserved the smaller distal articular surface of the proximal phalanx.

Surgical revision options for failed trapeziometacarpal total joint replacement include implant replacement and trapeziectomy. However, discontinuation of older implants complicates revision with original components, particularly as removing a well-fixed metacarpal stem can be challenging. This study examined the feasibility of pairing discontinued stems (Arpe, Elektra and Ivory) with currently available necks (Maïa, Moovis and Touch).

Trigger finger, or stenosing tenovaginitis, is a common condition characterized by impaired flexor tendon sliding due to thickening of the A1 pulley. While open surgical release remains the gold standard for the treatment of persistent trigger finger, there is increasing interest in minimally invasive ultrasound-guided techniques to improve precision and outcomes. The purpose of this study is to evaluate the outcomes, safety, and complications associated with ultrasound-guided trigger finger release using a minimally invasive surgical knife.

Ulnar styloid fractures occur frequently concomitant with distal radial fractures. Although unstable distal radial fractures are mostly surgically treated, ulnar styloid fractures are often ignored. Unstable fractures at the base of the ulnar styloid may lead to persistent ulnar pain, due to distal radioulnar joint instability or ulnar styloid non-union.

The purpose of this study was to analyse the anatomy of the trapezium with regard to cup position in trapeziometacarpal replacement and identify those trapeziums that are at risk of cup perforation through the trapezoid articular surface. The width of the proximal and distal articular surface and the height of the trapezium and second metacarpal facet were measured on 96 peritrapezial views reconstructed from computed tomography scans. The trapezoid articular surface of the trapezium (TRAST) angle was calculated, and four different cup designs were virtually positioned centrally in the trapezium and parallel to the proximal articular surface.

Emerging advances in immersive virtual reality incorporating optical hand-tracking present promising potential for application in orthopedic hand therapy. The system is designed to analyze hand movements, enabling users to "use" their hands virtually in any fabricated setting. This article, supplemented with videos, examines practical applications of immersive virtual reality in routine hand therapy and provides a scientific presentation of the interaction of immersive virtual reality with our physiological and neurological systems.

This report emphasizes careful consideration of surgical technique for intramedullary screw fixation in middle phalanx fractures. Highlighting pitfalls, particularly with K-wire placement, it suggests the antegrade trans-articular approach as superior, urging further research for improved patient outcomes.

Despite the low prevalence of each rare disease, the total burden is high. Patients with rare diseases encounter numerous barriers, including delayed diagnosis and limited access to high-quality treatments. In order to tackle these challenges, the European Commission launched the European Reference Networks (ERNs), cross-border networks of healthcare providers and patients representatives.

Article Synopsis
  • - Digital mucous cysts are benign, recurrent tumors found at the finger joints, often related to osteoarthritis, with multiple treatment options but no clear consensus on the best approach.
  • - A study involving 15 patients without osteoarthritis examined a novel non-surgical injection technique to treat these cysts, focusing on outcomes and complications over a 6-month follow-up period.
  • - Results showed an 80% complete resolution of cysts with no reported complications, suggesting this method is an effective, low-cost, and non-invasive alternative, particularly for patients without degenerative joint changes.

Objective: Management of recurrent Dupuytren's disease of the little finger is challenging. Various treatment modalities have been proposed: external fixation, local skin flap, dermofasciectomy, or even amputation. An alternative surgical technique was introduced by Honecker et al.

A 35 year-old right-handed female presented with persistent wrist pain lasting two years. Imaging disclosed an accessory tendon-shaped structure, identified as a Flexor Carpi Radialis Brevis, strangling the Flexor Carpi Radialis tendon at the wrist during effort. Surgical exploration found the insertion of the Flexor Carpi Radialis Brevis to be bifid.

The opposable thumb provides both stability and mobility and is needed to accomplish different prehensile tasks. The trapezium is a complex bone, with a distal articular surface that is convex in the sagittal plane of the thumb and concave in the coronal plane of the thumb. The numerous additional articulations with the carpus and the oblique orientation to the main plane of the hand makes it difficult to evaluate the trapeziometacarpal joint using standard hand or wrist radiographic views.

Background: Degenerative arthritis of the proximal interphalangeal (PIP) joint of the long fingers is a common disorder affecting mainly a female middle-aged population. Conservative treatment is often effective, but in some cases, pain can persist which can lead to invalidating function. Besides denervation and arthrodesis, arthroplasty is a valuable alternative treatment.

Traumatic lesions around the base of the thumb have special features due to the location and structure of the joint and its inherent potential instability. This causes different fracture patterns, which are mostly isolated around the metacarpal base but can also involve just the trapezium or both. Exceptionally, there may be isolated dislocation.

 Several volar plating techniques exist to treat distal radial fractures.  We investigated minimally invasive plate osteosynthesis (MIPO) with pronator quadratus (PQ) sparing versus conventional flexor carpi radialis approach for volar plating with PQ repair after distal radial fractures during the first postoperative year.  Prospective data of two consecutive cohorts were compared: 62 patients in MIPO group with an average age of 61.

We assess the distribution of trapezial inclination in a young population in order to propose a threshold for trapezial dysplasia. One hundred peritrapezial views were reconstructed from wrist computed tomography scan datasets to measure trapezial inclination. Seventy peritrapezial views were constructed from 10 datasets to assess the influence of radiograph rotation.

We present two recent cases of spontaneous rupture of both index finger extensor digitorum communis and extensor indices proprius tendons caused by a dorsal carpus osteophyte. Both patients had a history of scaphoid fracture non-union with evolution to scaphoid non-union advanced collapse (SNAC) of the wrist. These two cases were treated surgically with a 3-corner arthrodesis, and an interposition of a fragment of one of both ruptured tendons together with a tendon transfer of a supernumerary extensor digitorum communis of the third finger.

A case-control study was conducted to compare wound healing with or without skin suture after endoscopic carpal tunnel release. The primary endpoint was esthetics on the Manchester Scar Scale (MSS). Patients were recruited between April 2016 and April 2017.
