Proximal row carpectomy versus four-corner arthrodesis in the treatment of SLAC and SNAC wrist: meta-analysis and literature review.

A systematic literature review was performed on 84 articles from 2000 to 2020 on proximal row carpectomy (PRC) or four-corner arthrodesis (FCA) in patients with posttraumatic wrist osteoarthritis. Qualitative assessment was conducted on 14 articles. Pain, range of motion (ROM), grip strength and complications were analyzed using weighted average means.

Is DISI Deformity Related to Presence of a Medial Lunate Facet in Patients with Scapholunate Dissociation?

 Lunate morphology has been suggested to influence carpal kinematics.  We investigate a possible relation between presence of a medial lunate facet and dorsal intercalated segment instability (DISI) of the wrist in patients with a scapholunate (SL) dissociation.  We retrospectively reviewed patients diagnosed with SL dissociation between 2000 and 2017.

Long-term follow-up of the three-ligament tenodesis for scapholunate ligament lesions: 9-year results.

We report on a retrospective cohort of 50 cases of three-ligament tenodesis for scapholunate instability. Fifteen cases (30% of our cohort) needed salvage surgery (11 proximal row carpectomies, 2 partial and 2 total wrist fusions) at an average of 33 months and are considered "failures". Of the 35 remaining cases ("success"), 16 (32% of our cohort) were reviewed at average 111 months and had good functional outcomes (QuickDASH 18/100, PRWE 11/100, pain 1/10, satisfaction 9/10).

Metal ion levels in ceramic-on-ceramic THR with cobalt-chrome modular necks: analysis of cobalt and chromium serum levels in 23 healthy hip patients.

Background: Modular necks in total hip replacement (THR) can be a source of metal ion release.

Methods: We measured the level of cobalt (Co) and chromium (Cr) ions in the serum of 23 healthy volunteers with a well-functioning ceramic-on-ceramic THR of a particular design, containing a cobalt-chrome (Co-Cr) stem and a Co-Cr modular neck.

Results: Average Co in serum was 1,71 µg/l; median Co was 1.

Does the "three-ligament tenodesis" procedure restore carpal architecture in static chronic scapholunate dissociation?

The effect of the three-ligament tenodesis on the scapholunate angle and scapholunate gap was studied. A comparison was made between these angles preoperatively and postoperatively in 12 patients. There was a significant decrease in the scapholunate angle from 77 to 68 degrees, and the scapholunate gap was reduced from 4.
