NCT ID: NCT05574582 Recruiting - Scaphoid Fracture Clinical Trials

Arthroscopic vs. Open Bone Grafting for Scaphoid Delayed/Nonunion

Start date: February 15, 2023
Phase: N/A
Study type: Interventional

Single site, prospective, observer-blinded randomized controlled trial. Eighty-eight patients aged 18-68 years with scaphoid delayed/non-union, will be randomized, 1:1, to either open iliac crest cancellous graft reconstruction or arthroscopic assisted distal radius cancellous chips graft reconstruction. All Danish citizens, referred to the orthopedic department, Copenhagen University Hospital in Gentofte with scaphoid delayed/nonunion will be offered participation in the trial. Exclusion criteria are: Associated fracture in the hand/upper extremity, previous failed surgical treatment for scaphoid delayed/nonunion, stage 2 SNAC or above, avascular necrosis of the proximal pole and gross deformity. Patients are stratified for smoking habits, proximal pole involvement, and displacement of >/<2mm. The primary outcome is time to union, measured with repeated CT scans at 2-week intervals from 6 to 16 weeks postoperatively. Secondary outcomes are Quick disabilities of the Arm, Shoulder and Hand (Q-DASH), Visual Analogue scale (VAS), donor site morbidity, union rate, restoration of scaphoid deformity, range of motion, key-pinch, grip strength, EQ5D-5L, patient satisfaction, complications, and revision surgery. Patients are examined before the operation and 1.5, 3, 6, 12 and 24 month after the operation. Online follow-up 5 and 10 years after surgery are performed.

NCT ID: NCT04580225 Recruiting - Arthritis Clinical Trials

Randomized Comparison of PARtial Wrist Fusion With or Without Triquetral Excision (PARTE)

PARTE
Start date: January 7, 2021
Phase: N/A
Study type: Interventional

This randomized clinical trial (RCT) aims to compare clinical and radiographic outcomes of different partial wrist fusion techniques in participants with post-traumatic wrist arthritis. Participants with stage II or III scapholunate advanced collapse (SLAC) or scaphoid nonunion advanced collapse (SNAC) who meet the eligibility criteria will be randomly assigned to one of two parallel groups: Group A (partial wrist arthrodesis without triquetral excision i.e. four-corner arthrodesis), or Group B (partial wrist arthrodesis with triquetral excision i.e. three-corner or capitolunate arthrodesis with triquetral excision). The results of this study will provide evidence to guide surgeons in determining the ideal wrist fusion technique in the management of patients with post-traumatic wrist arthritis requiring surgery.
