Comparison of Treatment of Subtrochantric Fractures of Type 1 Femur with Condylar Dynamic Screw and Hip Dynamic Screw in Patients Referred to Shahid Beheshti Hospital in Yasuj During 2007-2017

Treatment of sub trochanteric fractures is very challenging for bone and joint surgeons. The techniques used to treat these fractures are fracture reduction and the use of condylar dynamic screws and hip dynamic screws. The aim of this study was to compare the treatment of sub trochanteric fractures of type A femur with condylar dynamic screw and hip dynamic screw in hospitalized patients in Shahid Beheshti Hospital, Yasuj, Iran, 2007- 2016 and Access is a better treatment that has fewer side effects and better rehabilitation.

This study is a study based on exist data that was performed by reviewing the files of 50 patients with sub trochanteric fracture type A hospitalized in Shahid Beheshti Hospital, Yasuj, Iran, 2007- 2016. These patients were randomly divided into two equal groups of 25 in terms of treatment with condylar dynamic screw (DCS) and hip dynamic screw (DHS). In these two groups, the variables of treatment failure, pain, and range of motion of the hip in three-month and six-month periods were compared. In order to compare the quantitative data between the two groups of failure therapy and the type of treatment intervention, K_S and MANN_WHITNEY U tests were used and qualitative data were compared from Chi-square test.

Of these 50 patients, 11 (22%) failed treatment, of which four (16%) were treated with DHS and seven (28%) with DCS. There was no statistically significant relationship between age (P = 0.1), sex (P = 0.3) and type of intervention (P = 0.9) with treatment failure. Treatment failure (approximately 90%) occurred in the first four months and all within six months.

Both treatments (using DCS and DHS) were optimally effective in the treatment of sub trochanteric fractures of type A and no statistically significant differences were observed between them.
