Historical notes Tendon surgery is as old as surgery itself
2698 BC – Yu-Fu 460BC – Hippocrates 280 BC – Herophilos from Chalkedon 129-199 – Galen 980-1037 – Avicenna 1641- Ambrosius Pare 1880 - Nikoladoni 1881 – Gluck 1882 – Henck Historical notes
Hippocrates – if injury of Achilles tendon occurs it would cause acute fever, convulsins etc. Avicenna - tenth century strongly advocated tendon suture World War I and II stimulated the development of modern hand surgery
Tendon consists of : Cells – fobroblastsCells – fobroblasts Extracellular matrixExtracellular matrix mainly collagen fibers, elastin fibers mainly collagen fibers, elastin fibers ground substance (proteoglicans, glycosaminoglycans, structural proteins, plasma proteins and other small molecules) ground substance (proteoglicans, glycosaminoglycans, structural proteins, plasma proteins and other small molecules)
Collagen typI – composed of three chains 70% glicine, 15% proline and 15% hydroxyproline Collagen molecules are combined in a right-handed triple helix. The stabilisation between helixs is maintain by hydrogens bonds.
Tendon reconstruction Primary end to end tendon suture. To 3-4 weeks. Secondary - staged techniques single stage – good conditions two stage – after complicated injuris 1-st stage – endoprothesis 2-nd stage – tendon graft.
Secondary tendon repair 1.One stage reconstruction FTG /free tendon graft/ 1.1. Bunnel graft zone I-IIII° wg Boys`a 1.2. Matev graft zone I-V 1.3. Interposition graft III-V 2. TFTI (temporary flexor tendon implant) 2.1. Short graft I-III 2.2. Long tendon graft I-V
Tendon reconstruction Tendon grafts Short – zone 1-3 Long – zone 1-5
Mallet finger Type I- closed trauma, with or without small avulsion fracture Type II- laceration, loss of tendon continuity Type III- II+deep abrasion Type IV- A-transepiphiseal plate fracture; B- fracture of artic. surf. 20-50%; C- fracture of artic. surf. >50%, or subluxation aDIP Zone I
Zone II 1.Open injury – tendon suture; immobilization in hyperextension for 6 weeks. 2.Closed injury- split in hyperextension in aPIP
Zones III, IV,V Open injury: -tendon suture, immobilization aPIP 0° to 5-6 weeks - exercise -Zone V – wrist immobilization in flexion 40°. MP joints in flexion 10-20°. Closed injury: - splint for 6 weeks
Zones VI-IX End to end tendon suture. Immobilization – wrist in hyperextension 40-45° for 4-5 weeks
