“…radiocarpal ligament, while HASTE images were acquired to capture the wrist in dynamic extension-flexion motion in a "real-time" cine acquisition. The dynamic HASTE images demonstrated a radiocapitate angulation of 87°± 8°in free wrist extension, which exceeded the reported value in asymptotic individuals measured using universal goniometer or iPhone 4 Gyroscope application (71°) (27) as well as that required for daily activities (64 ± 14°) (28). In this way, the glove coil and harness allowed extension beyond the clinically relevant range.…”

Background Wrist pain in the extended or extended weightbearing positions may be incompletely evaluated using standard magnetic resonance imaging (MRI) with standard rigid clamshell coils in the neutral position. Purpose To evaluate a flexible 24-channel glove coil and harness when imaging the wrist in neutral, dorsally extended, and weightbearing positions. Material and Methods Ten wrists in 10 asymptomatic volunteers (mean age = 29 years) were scanned. Participants underwent 3-T MRI using the harness and flexible glove coil, acquiring sagittal turbo spin echo (TSE) and half-Fourier acquisition single-shot turbo spin echo (HASTE) pulse sequences. Static TSE images were obtained in neutral, extended, and weightbearing positions using proton density parameters and independently evaluated by two radiologists for: dorsal radiocarpal ligament thickness; radiocapitate, radiolunate, and capitatolunate angles; palmar translation of the lunate on the radius; angulation of the extensor tendons; and distance from the distal extensor retinaculum to Lister's tubercle. Cine HASTE images were dynamically acquired between neutral-maximum extension to measure the radiocapitate angle. Results Good reader agreement was observed (r > 0.73) for all measurements except palmar translation in the neutral position (r = 0.27). Significant increases in dorsal radiocarpal ligament thickness; radiocapitate, radiolunate and capitolunate angulation; and extensor tendon angulation were observed between the neutral and extended positions ( P < 0.001). A further significant increase in these metrics between extended and weightbearing positions was also seen ( P < 0.01). Conclusion Significant increases in dorsal radiocarpal ligament thickness, articular and tendon angulations occur during wrist extension, that further increase with dorsal weightbearing.

“…They assessed wrist motion by asking the participants to perform 52 standardized tasks; the results showed that normal wrist ROM included 5° flexion, 30° dorsal extension, 10° radial deviation, and 15° ulnar deviation. In this context, a recent study showed that daily hand activities can be accomplished at 60% of the maximum ROM of the wrist ( Nadeem et al, 2022 ). This indicates that the ROM offered by the 3DMT-Wrist system is adequate for all requirements of daily life.…”

Background: Total wrist arthroplasty is an effective treatment for end-stage wrist arthritis from all causes. However, wrist prostheses are still prone to complications such as prosthesis loosening and periprosthetic fractures after total wrist arthroplasty. This may be due to the wrist prosthesis imprecise matching with patient’s bone. In this study, we designed and developed a personalized three-dimensional printed microporous titanium artificial wrist prosthesis (3DMT-Wrist) for the treatment of end-stage wrist joint, and investigated its safety and effectiveness.Methods: Total wrist arthroplasty was performed using 3DMT-Wrist in 14 cases of arthritis between February 2019 and December 2021. Preoperative and postoperative visual analog scale scores, QuickDASH scores, wrist range of motion, and wrist grip strength were evaluated. Data were statistically analyzed using the paired samples t-test.Results: After 19.7 ± 10.7 months of follow-up, visual analog scale decreased from 66.3 ± 8.9 to 6.7 ± 4.4, QuickDASH scores decreased from 47.4 ± 7.3 to 28.2 ± 7.6, grip strength increased from 5.6 ± 1.4 to 17.0 ± 3.3 kg. The range of motion improved significantly in palmar flexion (30.1° ± 4.9° to 44.9° ± 6.5°), dorsal extension (15.7° ± 3.9° to 25.8° ± 3.3°), ulnar deviation (12.2° ± 3.9° to 20.2° ± 4.3°) and radial deviation (8.2° ± 2.3° to 16.2 ± 3.1). No dislocation or loosening of the prosthetic wrist joint was observed.Conclusion: Total wrist arthroplasty using 3DMT-Wrist is a safe and effective new treatment for various types of end-stage wrist arthritis; it offers excellent pain relief and maintains the range of motion.

“…A comparative study (TWR vs. TWA) at a mean-time follow-up of 68 months revealed that patients with TWR rated their self-reported outcomes significantly better than patients with TWA for both in DASH (29 vs. 38, p value 0.41) and PRWE (31 vs. 73, p value 0.01) [20]. Noted that not more than 60% of the maximum wrist capacity is needed to maintain functional wrist motion for ADL [21].…”

Background Total wrist replacement (TWR) as motion-preserving procedure continues to be critically discussed in the literature, although the complication rates have been significantly reduced with the current 3rd generation designs compared with older types. Possible reasons for this are often also a lack of knowledge about the currently available evidence, the complication management, and the lack of practical experience by the surgeons. Methods Based on an extended review of literature and own experience, the aim of this article is to give practicable insights for the clinician on: (1) biomechanical fundamentals, (2) differences in design, survivorship and functional outcome between the recent types, (3) possible pitfalls, and (4) failures and salvage options. Results The goal of TWR is that the overall wrist motion is maintained respectively improved despite it works with a locked midcarpal joint. Regarding survivorship and functional outcome the Maestro is (was) being superior over all other types that is (was) based on features in design. There is no scientific evidence as to why the Maestro was withdrawn from the marketplace by the company. For assessment of instability and/or impingement the use of dynamic radiographs is recommended. The problem of TWR is unchanged failure of the carpal components primarily based on mechanical dysbalance, and secondarily followed by metal and/or polyethylene wear, but surgical revision of asyptomatic periprosthetic osteolysis without safe radiagraphic signs of loosening is only required in not more than 20% of cases. For a failed TWR, revision TWR or conversion to total wrist arthrodesis are viable salvage options. Conclusions The knowledge about recent evidence and features in design of the available types, exact assessment of radiographic findings, presence of technical skills by the surgeons, and observance of the patient's expectations are the basic requirements for a successful TWR.
