Imaging plays an essential role for the detection and analysis of pathologic conditions of the brachial plexus. Currently, several new techniques are used in addition to conventional 2D MR sequences to study the brachial plexus: the 3D STIR SPACE sequence, 3D heavily T2w MR myelography sequences (balanced SSFP=CISS 3D, True FISP 3D, bFFE and FIESTA), and(More)
In this paper we illustrate the principal extraspinal pathologies causing sciatica and new approaches for the study of structures such as the lumbosacral plexus (LSP). Visualisation of the LSP in its entirety is difficult with conventional two-dimensional MRI sequences owing to its oblique orientation. In our institution, we have found that the utilisation(More)
Kirschner wire (K-wire) fixation is a common technique aimed at treating unstable distal radius fractures. We report our experience with extrafocal K-wire fixation in the treatment of unstable distal radius fractures in 34 patients (AO classification: 10 A2, 5 A3, 14 C1, and 5 C2). The patients' median age was 63 years (range, 16-87 years). K-wires remained(More)
OBJECTIVES Management of traumatic lesions of the brachial plexus mainly depends on whether the injury is pre- (nerve root avulsion) or postganglionic (trunks and cords). The aim of this study was to assess the diagnostic and prognostic value of MRI in such lesions, and to determine any correlations among radiological, clinical and electroneuromyographical(More)
UNLABELLED Non-tuberculous mycobacterial infections of the hand are difficult to treat and require a long time before remission. But how long should we wait to see an improvement? To answer this question, the published scientific literature was reviewed in English, French and German. Tuberculosis, arthritis and osteomyelitis cases were excluded. A total of(More)
The aim of this retrospective study was to compare two techniques of ulna shortening for ulnocarpal abutment. The technique performed initially was diaphyseal osteotomy. Subsequently, a metaphyseal osteotomy was performed to avoid the drawbacks related to the plate. The study group consisted of 29 patients: 13 with diaphyseal and 16 with metaphyseal(More)
Proximal row carpectomy (PRC) is a well-accepted procedure for the treatment of early post-traumatic degenerative disease of the wrist. Much less frequently, PRC has been advocated as an emergency procedure for irreparable fracture-dislocation of the wrist. Our objective was to compare the results of PRC in patients having undergone this procedure in the(More)
The PI2® spacer is designed for treatment of trapeziometacarpal (TM) osteoarthritis. However, the shape of this implant has raised concerns about its stability. We retrospectively investigated 45 implants in 41 patients treated for trapeziometacarpal osteoarthritis in our hospital between 2004 and 2009 who underwent trapeziectomy and insertion of a PI2®(More)
Trichilemmal cyst is a benign tumor, developed from hair follicle, located mainly at the scalp. We report a clinical case of unusual location at the finger pulp confirmed by histology. The main differential diagnosis in this reported case was a whitlow. The origin of this cyst is probably the nail matrix whose keratinization is trichilemmal. Surgical(More)
The treatment of impacted distal radius fractures is complex. Internal fixation by a dorsal approach with arthrotomy should be considered, particularly when the fractures are dorsally comminuted. This was a retrospective, observational study of 26 patients operated between 2008 and 2012 who were reviewed in September 2013. In the surgical procedure, a(More)
