Whole body MR imaging in ankylosing spondylitis: a descriptive pilot study in patients with suspected early and active confirmed ankylosing spondylitis

Background  

Ankylosing spondylitis is a chronic inflammatory rheumatic disorder which usually begins in early adulthood. The diagnosis is often delayed by many years. MR imaging has become the preferred imaging method for detection of early inflammation of the axial skeleton in ankylosing spondylitis.     

Serratus anterior muscle transplantation for treatment of soft tissue defects in the hand

The inferior three slips of the serratus anterior muscle have been used as a free tissue transfer in 18 patients for the reconstruction of dorsal and palmar defects in the hand. Mean follow-up was 2.8 years. There were 12/18 flaps for palmar coverage and 6/18 for dorsal coverage. All flaps survived. On the basis of this experience we conclude that this flap has three attributes making it suitable for palmar and dorsal metacarpal resurfacing: (1) low donor site morbidity, (2) the three separate slips are easily divisible for contouring, and (3) durability and adhesion provide a stable resurfacing for grasp.     

Arthroscopic tarsometatarsal (Lisfranc) arthrodesis

We describe an arthroscopic approach of tarsometatarsal arthrodesis for post-traumatic arthritis. Five tarsometatarsal portals (medial, P1–2, P2–3, P3–4, P4–5) are identified at the junctional points between the metatarsals by means of image intensifier. The first metatarsocuneiform joint is approached through the medial and P1–2 portal. Articular cartilage is denuded and micro-fracture of subchondral bone is performed with an arthroscopic awl. The second metatarsocuneiform joint is approached through the P1–2 and P2–3 portals and the third metatarsocuneiform joint is approached through the P2–3 and P3–4 portals. The articular surfaces are prepared for arthrodesis. The articulations are kept in desired position and transfixed with 4.0 mm cannulated screws. The fourth and fifth metatarsocuboid articulations are rarely included in the procedure. Arthroscopic arthrodesis or tendon arthroplasty of the lateral column can be performed through the P3–4 and P4–5 portals.
