Three-dimensional (3D) printing is spreading in hand surgery. There is an increasing number of practical applications like the training of junior hand surgeons, patient education, preoperative planning, and 3D printing of customized casts, customized surgical guides, implants, and prostheses. Some high-quality studies highlight the value for surgeo...

Trichophyton verrucosum is a pathogen causing superficial mycoses in cattle worldwide and is one of the few zoophilic dermatophytes. Farmers and veterinarians are at a higher risk for infection owing to frequent direct animal contact. An increase in cases among humans has been observed in the past few years. We report a rare case of T verrucosum of...

Zusammenfassung Hintergrund Arthrotische Veränderungen der Fingergelenke sind häufig, insbesondere in der älteren Population. Unbehandelt können diese zu Schmerzen, Deformität, Instabilität oder Bewegungseinschränkung führen. Nebst Denervation und Arthrodese ist der prothetische Gelenkersatz eine mögliche operative Behandlungsmethode. Patienten/Mat...

Zusammenfassung. Bereits Ende des 19. Jahrhunderts wurden erste endoprothetische Eingriffe durchgeführt, jedoch begannen sich Mediziner erst Mitte des 20. Jahrhunderts intensiver mit dem Gelenksersatz im Bereich der Hand zu befassen. Heute gibt es für fast jedes Gelenk der Hand und des Handgelenks eine Auswahl an Prothesen. Im Bereich der Fingergru...

The reported use of 3D printing in hand and wrist rehabilitation has been mostly limited to feasibility studies and case series so far. Some of the reasons are the lack of purpose-built scanning applications, complicated digital design software, and lengthy and error-prone printing processes. We propose a multidisciplinary workflow for in -hospital...

IntroductionThis study evaluated the use of a free vascularized bone graft with and without cartilage from the medial femoral condyle (MFC) in patients with recalcitrant scaphoid non-union, with a special focus on union rates and the osteochondral graft for proximal pole destruction.Materials and methodsThirty-eight avascular scaphoid non-unions in...

Introduction Several methods treating proximal interphalangeal joint (PIP) fracture dislocations have been established providing early joint mobilization. The aim of this study was to evaluate the clinical and radiological outcome of unstable fracture dislocations of the PIP treated with a parabolic dynamic external fixator consisting of two Kirsch...

Introduction Since March 2011, the microbial collagenase of Clostridium histolyticum (Xiapex®, Swedish Orphan Biovitrum AB, Stockholm, Sweden) has become available in the European Union for treatment of Dupuytren’s disease. The purpose of this study was to evaluate potential safety risks of Xiapex® and to contribute to a better understanding for it...

Background Fragment-specific fixation of the distal radius is born to fix each articular fragment with limited surgical approach and low-profile devices. Over time, many devices with different designs and characteristics have been developed. However, many of them have showed the inability to securely fix marginal, small, and comminuted fragments as...

Objective: Anesthesiologic method with low bleeding level, risk level, and complication rate for surgical procedures on the hand without a tourniquet on an unsedated patient with the possibility for functional testing during surgery. Indications: Surgical procedures of the hand can be carried out using the wide awake technique depending on the p...

Background: Dupuytren's disease as a benign fibroproliferative disease leads to hyperplasia of the collagen fibers of the fascia of the palm, which can result in severe impairment of the functionality of the hand. Objectives: Examination of the significance of non-operative treatment of Dupuytren's disease with injectable collagenase clostridium...
