Diagnostic and Surgical Arthroscopy of the Metacarpophalangeal and Metatarsophalangeal Joints

Identification and treatment of osteochondritis dissecans of the distal sagittal ridge of the third metacarpal bone

“…Arthroscopic surgery was performed using a modification to the standard dorsal approach to the MCP . Following maximal distension of the joint, the arthroscopic portal was made distal to the proximodistal midpoint of the dorsal outpouching.…”

“…Brown pigment consistent with haemosiderin deposition was evident in planes of separation/cleavage between osteochondral fragments/flaps and the underlying subchondral bone in 9 joints. In all cases osteochondral flaps and fragments were removed and the defects debrided in line with accepted arthroscopic protocols (Fig b) . The joints were then lavaged and evacuated before skin portals were closed routinely.…”

“…Lesions may be confined to this or involve also the adjacent Mc/tIII condyles . The lesions are considered to be more common in MTP than MCP joints .…”

Ultrasound Assisted Arthroscopic Approach for Removal of Basilar Sesamoid Fragments of the Proximal Sesamoid Bones in Horses

“…A conventional palmar/plantar arthroscopic approach to the fetlock joint was used . A medial/lateral arthroscope portal was placed proximally in the palmar/plantar pouch.…”

“…Techniques for removal of articular and extra‐articular fragments at the base of the proximal sesamoid bone have been reported . Surgical approaches for removal of basilar fragments include arthrotomy, arthroscopy, and an approach through the digital flexor tendon sheath.…”
