Transition metal dichalcogenides are promising candidates to show long-range ferromagnetic order in the single-layer limit. Based on ab initio calculations, we report the emergence of a charge density wave (CDW) phase in monolayer 1T-CrTe$_2$. We demonstrate that this phase is the ground state in the single-layer limit at any strain value. We obtain an optical phonon mode of $1.96$ THz that connects CDW phase with the undistorted 1T phase. Localization of the $a_{1g}$ orbital of CrTe$_2$ produces an out-of-plane orientation of the magnetic moments, circumventing the restrictions of the Mermin-Wagner theorem and producing ferromagnetic long-range order in the two-dimensional limit. This orbital-localization is enhanced by the CDW phase. Tensile strain also increases the localization of this orbital driving the system to become ordered. CrTe$_2$ becomes an example of a material where the CDW phase produces the stabilization of the long-range ferromagnetic order. Our results show that both strain and phase switching are mechanisms to control the 2D ferromagnetic order of CrTe$_2$.

Distal radioulnar joint (DRUJ) arthritis is a common cause of ulnar wrist pain in rheumatoid and osteoarthritis. Modified arthroplasty for the DRUJ is a minimally invasive procedure for the treatment of isolated DRUJ osteoarthritis. The purpose of this study was to evaluate the efficacy of the procedure and the incidence of related ulnar wrist pathology as well as the incidence of subsequent ulnar wrist surgeries. All patients having modified arthroplasty for the DRUJ between 1994-2008 were retrospectively reviewed. Measurements included range of motion, grip strength, and subjective status. Data regarding other wrist surgeries was recorded. There were 29 patients, 23 of which had a follow-up of over 8 weeks (average 16 months (SD=24). Fourteen patients had no to minimal pain, 6 had pain with heavier activities (2 severe), and 2 reported constant pain at the surgical site. Of the 4 more painful patients, three had additional surgery after the DRUJ arthroplasty. In all 96% of the patients had another procedure involving the ulnar- wrist complex either prior to surgery, at the time of surgery or following surgery for modified arthroplasty. We suggest that pathology involving the ulnar-wrist complex is often a syndrome consisting of multiple related diagnoses including but not limited to arthritis of the DRUJ. Multiple procedures may be needed, or a more aggressive approach such as ulnar head replacement may be indicated so that pathology at both the distal radioulnar and ulnocarpal joints is addressed concomitantly.
