– See: Infections of the Hand – Anatomy: – extends mediolaterally from long metacarpal bone to the thenar eminence; – extends proximodistally from transverse carpal ligament to just proximal to superfical palmar arch; – borders of the thenar space include: – … Read more
– Discussion: – can be used for coverage of finger tip injuries the index, long, ring, (and in some cases the little finger); – can be used in children and young adults (esp. women) – Advantages: – more subcutaneous fat available than cross finger flap … Read more
– Discussion: – indicated primary for traumatic peripheral ulnar sided TFCC tears; – negative predictive factors for successful repair include concomitant ulnocarpal impaction syndrome (associated w/ degenerative tears) and peripheral radial tears (due to the relative avasucularity of the disc in this region; – some surgeons feel … Read more
– See: Ligaments of the Wrist – Discussion: – lunotriquetral interosseous ligament tear – relatively frequent occurance; – scapholunate dissociation – less frequent occurance; – ulnocarpal impaction syndrome (which can also mimic TFCC tear); – … Read more
– See: Ligaments of the Wrist – Exam of TFCC Injury: – tenderness is usually centered about dorsal depression distal to ulnar head, or it may be localized around the ulnar styloid; – patients may also note tenderness between the triquetrum and the ulnar styloid; – … Read more
Discussion overuse syndrome or tendinosis involving the region of the lateral humeral epicondyle; most often the origin of the ECRB displays an abnormal vascular proliferation and focal hyaline degeneration; ref: Anatomic Factors Related to the Cause of Tennis Elbow EDC may also be involved in some cases; ref: The role of the extensor digitorum communis … Read more
– See: Technique of Free Tendon Grafting – Discussion: – indications for tenolysis include failure to improve ROM after 3 months; – if patient has had previous flexor tendon repair, surgery should be delayed until 6 months post op (inorder to avoid tendon rupture); – consider using a wrist block … Read more
– Discussion: – core suture techniques; – strength of flexor tendon repair is proportional to the number of sutures crossing the repair; – note that a average force of 20 N required for active digital flexion in humans and most tendon repair techniques need initial strength of more than … Read more
