Teknik we dɛn kin yuz fɔ put di tin dɛn we dɛn dɔn put insay:

• Han-advans ova gaydway; ajɔst ridyushɔn if rɛsistɛns de apin.

• Mentεn rεdukshכn di tεm we yu de pas fכ distal frakshכn.

6. Intalɔk Skru Fikseshɔn

Strateji fɔ Sikyɔn

• Lεngth-stebul frakshכn: Proksimal lכk fכs (singl skru alaw dynamization).

• Lεngth-unstable/comminuted fractures: Distal lכk fכs we dεn de fala 'bakslap' fכ kכmprεs.

Prɔksimal Lɔk

• ≥2 skru via aim divays (multidayrekshכnal fכ proksimal frakshכn).

Distal Lɔk we dɛn kin yuz
