Lafta Ahraamta waa lafo yar oo qaab-jilicsan oo ku taal curcurka, gaar ahaan safka fog ee lafaha carpal. Waxa kale oo loo yaqaan lafta triquetral sababtoo ah qaabkeeda saddexda dhinac ah. Lafta pyramidal waxay ku qeexdaa lunate, pisiform, iyo lafaha hamate, iyo sidoo kale lafaha radius iyo ulna ee cududda. Shaqadeeda ugu weyni waa in ay siiso xasilooni iyo taageero wadajirka curcurka, iyo sidoo kale in ay gacan ka geysato dhaqdhaqaaqyada curcurka sida dabacsanaanta, fidinta, iyo afduubka.
