Lunocapitate versus four-corner fusion in scapholunate or scaphoid nonunion advanced collapse: a randomized controlled trial.

This pragmatic randomized controlled trial compared lunocapitate fusion (LCF) and four-corner fusion (4CF) for scapholunate advanced collapse (SLAC) and scaphoid nonunion advanced collapse (SNAC) in 64 patients. The primary outcome was change in grip strength from preoperative to 1 year postoperatively. The secondary outcomes were Disability of the Hand, Arm, and Shoulder score, Patient Rated Wrist Evaluation score, EuroQol-5D-3L, range of motion, key pinch strength and complications 12 months postoperatively.

Residual flexion deformity after scaphoid nonunion surgery: 7-year follow-up study.

The clinical implication of a residual flexion deformity following surgery for scaphoid nonunion is unclear. Sixty-three patients who underwent scaphoid nonunion surgery were assessed after a mean of 7 years (range 5-10) to analyse the outcomes based on the presence of residual scaphoid deformity. Primary outcome was Disabilities of the Arm, Shoulder and Hand score.

The impact of psychological factors on outcome after salvage surgery for wrist osteoarthritis.

This prospective longitudinal study of 80 patients analysed the effect of preoperative pain catastrophizing, anxiety, depression and sense of coherence on the Disabilities of the Arm, Shoulder and Hand, Patient-Rated Wrist Evaluation, quality of life, grip strength and range of motion during the first year after salvage surgery for wrist osteoarthritis. Generalized estimating equations were used to analyse the effect of the psychological factors on the outcome variables. Pain catastrophizing or a tendency for anxiety preoperatively had a strong negative impact on postoperative Disabilities of the Arm, Shoulder and Hand and Patient-Rated Wrist Evaluation.

There is motion between the scaphoid and the lunate during the dart-throwing motion.

Scaphoid and lunate mobility has been suggested to be minimal during the dart-throwing motion in studies based on serial computed tomography (CT) scans and cadaver studies. This study analyzes the direct motion between the scaphoid and the lunate during the dart-throwing motion . We examined nine individuals with standard CT scans of the wrist in radial extension and ulnar flexion.

Triquetral Motion Is Limited After Lunocapitate Arthrodesis.

Purpose: Lunocapitate arthrodesis is a motion-preserving salvage procedure for painful wrist osteoarthritis. Because the arthrodesis is limited to the capitate and the lunate, the adaptive motion of the triquetrum is theoretically maintained. We aimed to examine whether triquetral motion is sustained after lunocapitate arthrodesis.

The epidemiology of scaphoid fractures in Sweden: a nationwide registry study.

The epidemiology of scaphoid fractures has been described in limited populations, and incidence reports have been inconsistent. We investigated the nationwide incidence of scaphoid fractures by evaluating data on 34,377 patients in the Swedish National Patient Register for the years 2006-2015 regarding diagnosis, age, sex and treatment. The data were validated in 300 random patients, and incidence rates were adjusted accordingly.
