Etiology Mechanism of TFCC injury Type 1 traumatic injury Type 2 degenerative injury Anatomy dorsal and volar radioulnar ligaments central articular disc meniscus homolog ulnar collateral ligament origin of ulnolunate and ulnotriquetral ligaments Blood supply periphery is well vascularized (10-40% of the periphery) central portion is avascular Origin dorsal and volar radioulnar ligaments originate at the sigmoid notch of the radius dorsal and volar radioulnar ligaments converge at the base of the ulnar styloid Classification Presentation Symptoms wrist pain turning a door key often painful Physical exam positive "fovea" sign pain elicited with ulnar deviation (TFCC compression) or radial deviation (TFCC tension) Imaging Radiographs usually negative zero rotation PA view evaluates ulnar variance dynamic pronated PA grip view may show pathology Arthography joint injection shows extravasation MRI has largely replaced arthrography tear at ulnar part of lunate indicates ulnocarpal impaction sensitivity = 74-100% Arthroscopy most accurate method of diagnosis indicated in symptomatic patients after failing several months of splinting and activity modification Differential Ulnocarpal abutment syndrome Ulnar styloid impaction syndrome Pisotriquetral arthritis Treatment Nonoperative immobilization, NSAIDS, steroid injections Operative arthroscopic debridement arthroscopic repair ulnar diaphyseal shortening Wafer procedure limited ulnar head resection Darrach procedure Techniques approach technique pros & cons Arthroscopic repair approach technique pros & cons complications Ulnar diaphyseal shortening approach technique pros & cons complications Wafer procedure approach technique pros & cons Limited ulnar head resection approach technique pros & cons approach technique pros & cons complications Create a free account or log in to see the cards.
In addition, vitamin B12 is necessary for myelin sheath and nerve conduction, for neurotransmitters and brain metabolism, and for maintaining mood
Finally, it was suggested that I get my testosterone levels checked
After oral or intravenous administration, engineered live bacteria may colonize and proliferate in non-target sites, making it impossible to achieve spatiotemporal control for their clearance [202]
As proposed as result of the in planta enzyme activities, this finding confirms that most of the GSAAT protein is always predominantly reduced in planta under standard light conditions ( Supplementary Figure 3F )
