ABSTRACT

Objectives: Major surgical approaches for volar plating of the distal radius include the standard flexor carpi radialis (FCR) approach, the extended FCR (eFCR) approach, and the extended FCR approach combined with radial-sided carpal tunnel release (eFCR+CTR). The purpose of this study was to determine which of these three surgical approaches offers the greatest exposure and visualization of the distal radius. Methods: Sequential dissections were performed on each of 30 fresh frozen below elbow cadaveric samples in order to simulate the three surgical approaches for distal radius volar plating, starting with the standard FCR approach, advancing to eFCR, and finishing with eFCR+CTR. Prior to the initial dissection of each cadaveric sample, radiographs were taken in order to calculate the total area of the distal radius. Then, following each sequential dissection, photographs were taken of each specimen and analyzed with an image measuring software in order to obtain the area of distal radius exposed. The percentage of total distal radius exposure was then calculated for each of the three surgical approaches. Results: The eFCR+CTR approach offered the greatest average distal radius exposure at 87% of total distal radius visualized. The eFCR approach provided the next greatest exposure with an average of 73% visualized, followed by the standard FCR approach with an average of 61% visualized. Conclusion: The extended FCR approach with radial-sided carpal tunnel release is both safe and efficacious for osteosynthesis of distal radius fractures in the setting of concomitant carpal tunnel syndrome. This study demonstrates that an additional advantage of this approach includes improved surgical exposure and visualization of the distal radius. This surgical approach is a valuable addition to any upper extremity surgeon's armamentarium and should be considered when treating difficult distal radius fractures.

ABSTRACT

Painful end-stage wrist osteoarthritis (OA) unresponsive to conservative treatment is frequently managed with total wrist arthrodesis (TWA), which might render pain alleviation and ameliorate function, pain, and grip strength. Usual indications for TWA include inflammatory arthritis, idiopathic degenerative OA and posttraumatic OA, Kienböck's illness, brachial plexus palsy, cerebral paralysis, infraclavicular brachial plexus blocks and other spastic and contracture base illnesses, scapholunate advanced collapse, scaphoid nonunion advanced collapse, and failure of other surgical techniques such as after failed total wrist arthroplasty, four-corner fusion, proximal row carpectomy and severe ligament injuries (this procedure is carried out when all other treatment alternatives have failed to control the individual's symptoms). TWA is commonly carried out with a dorsal plate fixed from the distal radius to the third metacarpal. However, other surgical procedures have been reported, including intramedullary fixation and new implants that do not cross the third carpometacarpal joint or some procedures without utilizing hardware for example using a vascularized fibular grafting In individuals with rheumatoid arthritis. TWA has been shown to give persistent and painless stability for 20 years or more. The rate of adverse events for TWA ranges from 0.1% to 6.1%, though some authors have published that it can be as high as 27%. The most common adverse events are tendon ruptures, peri-implant fractures of the third metacarpal, the need for hardware removal, and constant pain at the third carpometacarpal joint. In idiopathic degenerative OA, the reoperation rate following TWA has been reported as high as 63%. While TWA can render foreseeable pain alleviation and ameliorate function, orthopedic surgeons should remember that this surgical technique is not without its risks and that the accessibility of many surgical procedures requires orthopedic surgeons to scrupulously contemplate the risks and benefits of each alternative for the individual in front of them.
