Does the distance of the fixation points to the fracture affect healing in tibial shaft fractures treated with openable distal claw intramedullary nail?

Objective: A retrospective examination was made of tibia shaft fractures treated with intramedullary nail (IMN), which are designed distal retractable claws, unlike classic imtramedullar nails. It aimed to evaluate the effect on healing diameter and distance between fracture line proximal fixation points IMN. Material Method: The study included 28 patients (18 males, 10 females; mean age 43.75 (18-69) years) claw IMN (Dunitech Nite Tibial Oliga Med Ankara-Turkey) for a diagnosis unilateral diaphyseal January 2020 2022. midpoint (F), point locking screw (S), (T), isthmus mid-point (I) were determined as reference points. FT, ST, IT distances, (ND) (ID) measured FT/ST ratio calculated. Statistical evaluations relationships length measurements visual analog scale (VAS) radiographic union score (RUST) scores at end one year. Results: No statistically significant correlation RUST VAS or IMN.Conclusion: There no in claws. design claws provides strong stable healing. operating time is shorter resulting less radiation exposure.
