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.

Failures of the three-ligament tenodesis for chronic static scapholunate dissociation are due to insufficient reduction.

We retrospectively reviewed 13 patients who had successfully undergone three-ligament tenodesis for scapholunate instability, and compared the radiological outcome with 14 failed cases. The scapholunate angle in the failed group increased from 73 degrees to 81 degrees with a scapholunate gap of 532 mm, compared to a decrease in the successful group from 76 degrees to 66 degrees with a scapholunate gap of 2.94 mm.

Delayed migration of a metal suture anchor into the glenohumeral joint.

Intra-articular migration is a known complication of poorly placed metallic suture anchors in rotator cuff repair and labral reconstruction. We report a case of intra-articular migration of a metallic suture anchor seven years after open labral reconstruction. Despite the fact that the patient remained asymptomatic for seven years, presence of an extra-osseous anchor was already noted postoperatively.

Reliability and reproducibility of Kienbock's disease staging.

We evaluated the interobserver reliability and intraobserver reproducibility of the Lichtman et al. classification for Kienböck's disease by getting four observers with different experience to look at 70 sets of wrist radiographs at different points in time. These observers staged each set of radiographs.

Negative ulnar variance has prognostic value in progression of Kienböck's disease.

The radiographic files of 70 patients with Kienbock's disease were analyzed. Ulnar variance, carpal height and Kienbick stage were determined. A significant difference in ulnar variance was seen between early and late stages of the disease.
