Lintlha tsa Lihlahisoa
E entsoe ka thepa ea TC4.
Mefuta ea li-screw ke HA cortical bone screw, HB cancellous bone screw le HC locking screw.Li-screw tsa HB li fumaneha ka khoele e felletseng le khoele ea halofo.
Li-crews tsa boholo bo fapaneng li na le lisebelisoa tsa ho buoa tse tsamaellanang.
Boholo ba HA: Φ2.0, Φ2.5,Φ2.7, Φ3.5, Φ4,5
Boholo ba HB;Φ4.0 e tletse, Φ4.0halofo, Φ6.5 e tletseng, Φ6.5halofo
Litlhahiso tsa Bongaka
Li-screws tse tloaelehileng tsa cortical li sebelisoa bakeng sa masapo a diaphyseal, a nang le hlooho e lekanang (3.5 + 4.5) le likhoele tsa asymmetrical.
Li-screws tse tloaelehileng tsa ho hlakola masapo li sebelisetsoa metaphysis kapa epiphysis, tse nang le bophara bo boholo ba ka ntle le khoele e tebileng.
Theknoloji ea "lag screw" e na le likarolo tse peli tsa mochini: 1 matla a circumferential (matla a khohlano) haufi le khoele, 2 matla a axial ha a tiisa, screw screw kapa lesoba le thellang le lumella "contralateral fracture block" hore e huleloe hloohong.
