Radiography versus computed tomography for osseous staging of Kienböck's disease.

This retrospective study compared the diagnostic accuracy of conventional radiography (CR) and computed tomography (CT) in classifying Kienböck's disease (KD) according to Lichtman staging. Besides age, cartilage condition and vascularity, bone morphology is important in choosing the most appropriate treatment in KD. In 278 patients, two musculoskeletal radiologists performed a consensus reading of 281 lunate necroses according to the Lichtman classification, based on CR and CT.

[Fractures and Non-Unions of the Scaphoid: Our preferred surgical Approaches].

This article describes our algorithm for approaching and fixing scaphoid fractures and non-unions.

[Incisions in surgical Treatment of Dupuytren's Disease].

Therapeutic options to treat Dupuytren`s disease vary considerably. Nevertheless, limited fasciectomy remains the method of choice in advanced disease. Correct incisions are of crucial importance in this kind of surgery.

[Revision surgery after resection arthroplasty of the CMC-1 joint using the extensor carpi radialis longus muscle tendon].

Objective: Resuspension of the first metacarpal bone using the extensor carpi radialis longus muscle tendon. Prevention of contact between the first metacarpal bone and adjacent bones (scaphoid, trapezoideum, second metacarpal bone). Preservation of motion.

[Scaphoid non-union: Experience from more than 280 reconstructions using a medial femur condyle bone graft].

Background: Since 2008 we have been using many free vascularized medial femoral condyle grafts for reconstruction of difficult scaphoid non-unions. This article aims to report our results and experiences.

Patients And Methods: Until the end of 2019 a total of 287 patients had a microvascular scaphoid reconstruction, 158 with use of a corticocancellous, and 129 using an osseocartilaginous graft.

The importance of radial multiplanar reconstructions for assessment of triangular fibrocartilage complex injury in CT arthrography of the wrist.

Background: Triangular fibrocartilage complex (TFCC) lesions commonly cause ulnar-sided wrist pain and instability of the distal radioulnar joint. Due to its triangular shape, discontinuity of the TFCC is oftentimes difficult to visualize in radiological standard planes. Radial multiplanar reconstructions (MPR) may have the potential to simplify diagnosis in CT wrist arthrography.

[Not Available].

Background: Because of its form, size and position, the scaphoid is known to be the foundation stone of the carpus, with an exceptionally important biomechanical function. Therefore evaluation of fracture morphology is essential. Experts already agree that computed tomography (CT scan) in the long axis of the scaphoid is the best approach for diagnosing scaphoid fractures, but also for therapy planning.

[Results of the reconstruction of the middle phalangeal base of the finger through an osteochondral autograft from the hamate bone].

Objective: The fractured base of the middle phalanx was reconstructed in 13 patients using an osteochondral transplant from the carpometacarpal joint surface of the hamate bone. The goal was to restore joint stability with preservation of mobility. Indications were acute and missed isolated destruction of the palmar middle phalanx base ≥ 30 %.

STT arthrodesis versus proximal row carpectomy for Lichtman stage IIIB Kienböck's disease: first results of an ongoing observational study.

Introduction: Scapho-trapezial-trapezoidal (STT) arthrodesis and proximal row carpectomy (PRC) are used for the treatment of Lichtman stage IIIB Kienböck's disease. This study prospectively compares 1-year results of STT arthrodesis and PRC in Lichtman stage IIIB Kienböck's disease.

Materials And Methods: Nineteen patients were operated: eight with STT arthrodesis and 11 with PRC.

[Total wrist fusion using the AO wrist fusion plate].

Objective: Arthrodesis of the wrist in order to improve functional use of the hand by reducing pain and improving grip strength.

Indications: Painful destruction of both the radiocarpal and mediocarpal joint combined with contraindications to motion-preserving procedures. Conservative treatment insufficient.

[Stabilization of the scaphoid according to Brunelli as modified by Garcia-Elias, Lluch, and Stanley for the treatment of chronic scapholunate dissociation].

Objective: Stabilization of the scaphoid correcting rotary subluxation and replacement of the biomechanically essential dorsal part of the scapholunate ligament for prevention of osteoarthritis.

Indications: Scapholunate dissociation without useful remnants of the ligament and reducible malalignment of the scaphoid.

Contraindications: Fixed scaphoid malalignment.

[Treatment of chronic scapholunate dissociation using Cuénod's bone-ligament-bone autograft].

Objective: Correction of chronic scapholunate dissociation by replacement of the biomechanically most important dorsal part of the scapholunate ligament using a bone-ligament-bone autograft taken from the carpometacarpal joint II and, additionally, a modified dorsal capsulodesis.

Indications: Nonfixed chronic scapholunate dissociation without useful remnants of the ligament in which loss of the dorsal part of the scapholunate ligament is the crucial pathophysiological moment.

Contraindications: Chronic scapholunate dissociation with fixed deformity.
