A case is presented of a 78-year-old woman who sustained a re-fracture of the distal radius after initial fixation with a volar locking plate. The fracture was located in the mid-portion of the volar plate with palmar apex bending of the plate and signs of median nerve compression. A successful closed reduction was performed without hardware failure. The fracture united uneventfully.

We reviewed a series of 79 distal radial fractures with volar displacement which had been fixed internally using a buttress plate. The fractures were classified using the Frykman and AO systems; 59% were intraarticular. Complications occurred in 40.5% of cases; malunion was most frequent (28%). Functional recovery in patients with malunion was significantly worse than in those with good anatomi...

PURPOSE To review 9 cases of mechanical failure of the volar locking plate for distal radial fractures. METHODS Records of 374 consecutive patients who underwent volar locking plating for distal radial fractures were reviewed. Mechanical failures of the volar locking plate were defined as plate breakage or bending, screw breakage or loosening, or collapse of articular fragments resulting in i...

To investigate the cause of rupture of the flexor pollicis longus (FPL) after volar plate fixation of distal radius fractures, previous studies have examined the shape of the distal radius in the sagittal plane or in the lateral view. However, there are no reports on the anatomical shape of the volar surface concavity of the distal radius in the axial plane. We hypothesized that this concavity ...

UNLABELLED Background. A study was designed to compare the efficacy of anesthesia between transthecal digit block (TDB) and single injection volar subcutaneous block. METHODS A 36-patient, randomized, controlled, prospective investigation was undertaken. The parameters included the onset of time to achieve anesthesia, visual analog scale pain score during the infiltration, and anesthesia ...

The present study examined our ability to identify the location of a single vibration delivered to the dorsal and/or volar side of the forearm near the wrist. Three participants took part in three absolute identification experiments. In Exps. I and II, a 3-by-3 tactor array was placed on the dorsal and volar side of the wrist, respectively. In Exp. III, two 3-by-3 tactor arrays were placed on b...

The aim of this study was to determine the relationship between volar plate removal and the Soong classification following fixation for fractured distal radius. In this retrospective cohort study, all consecutive patients who had volar plate fixation for a distal radius fracture in 2011-2015 were reviewed. Differences in Soong classification between patients who had plate removal and those who ...

The recent development of advanced high-resolution transducers has enabled the fast, easy, and dynamic ultrasonographic evaluation of small, superficial structures such as the finger. In order to best exploit these advances, it is important to understand the normal anatomy and the basic pathologies of the finger, as exemplified by the following conditions involving the dorsal, volar, and latera...

The functional roles of the three-dimensional fibrillar ultrastructure of the proximal interphalangeal joint volar plates of human fingers were studied by light microscopy and scanning electron microscopy. The results revealed that the volar plate consists of three layers of fibers. The first layer forms an intracavity wall with two parts, the proximal "membranous portion", and the distal "meni...
