Introduction: Rupture of the extensor tendons secondary to fractures involving the distal radius is a well-recognized rare complication. In patients with implants particularly, there exists a tendency for attributing the implant as a cause for the tendon rupture. We retrospectively studied the patients with extensor tendon injuries related to distal radius fractures, analyzed the factors leading to the rupture, suggest few preventive measures and describe the management strategy of these ruptures.
Materials And Methods: 21 patients who were treated for extensor tendon rupture following distal radius fractures in the period of 2014-2022 were retrospectively analyzed. 19 patients had been managed with surgery and two patients conservatively for the distal radius fracture. The time interval between the fracture fixation and tendon rupture, the time interval between tendon rupture and presentation, the extensor tendons injured and the position of the impinging screws or bony spur in relation to the extensor compartments, necessity for implant removal and modality of tendon reconstruction were studied in these patients.
Results: Extensor pollicis longus was found to be ruptured in all the patients except one patient with Extensor indicis proprius rupture alone. The time interval between the fracture fixation and tendon rupture averaged at 32.5 months. End to end repair of the ruptured tendons was never possible even in patients who presented earlier. 10 patients underwent intertendinous bridge grafting and 11 patients underwent tendon transfer. All the patients achieved full extension of thumb with no donor deficit.
Conclusion: Distal radius fracture related extensor tendon injuries pose a technical challenge to the surgeon and concern to the patient in the form of recurring surgeries. However, with immediate presentation to the surgeon and their use of appropriately designed management algorithm, these patients could be immensely satisfied with the outcome.

Treatment of distal radial fractures that include small anterior rim fragments can be difficult. We retrospectively reviewed 19 patients in whom an anterior rim plate with locking screws was used. After a median follow-up of 18 months (range 6-32; interquartile range (IQR) 14, 26), the median wrist flexion and extension arc was 70° (range 50-80; IQR 60, 70), the median grip strength was 80% of the contralateral side (range 52-104; IQR 77, 88), the median visual analogue scale score for pain was 0 (range 0-5; IQR 0, 1), the median disabilities of the arm, shoulder and hand score was 2 (range 0-59; IQR 0, 11) and the median modified Mayo wrist score was 80 (range 35-100; IQR 75, 85).

The main objectives of this work are to validate a 1D-0D unsteady solver with a distributed stenosis model for the patient-specific estimation of resting haemodynamic indices and to assess the sensitivity of instantaneous wave-free ratio (iFR) predictions to uncertainties in input parameters. We considered 52 patients with stable coronary artery disease, for which 81 invasive iFR measurements were available. We validated the performance of our solver compared to 3D steady-state and transient results and invasive measurements.

Background: Unstable diametaphyseal radius fractures (DMRFs) can be prone to complications, and treatment strategies are heterogeneous. Studies are difficult to interpret as definitions of the diametaphyseal junction zone (DMJZ) are impractical for clinical use, imprecise, or prone to error.
Methods: We introduce the forearm fracture index (FFI) to define DMRFs in radiographs and ultrasound.

Background: Early-term complications may not predict long-term success after adult cervical deformity (ACD) correction.
Objective: Evaluate whether optimal realignment results in similar rates of perioperative complications but achieves longer-term cost-utility.
Study Design: Retrospective cohort study.
