ABSTRACT
Objective To compare clinical efficacy of inverse less invasive stabilization system (LISS) and Gamma nail in treating unstable femoral intertrochanteric fractures combined with lateral wall fractures.Methods Fifty-two patients with intertrochanteric fractures associated with lateral wall fractures followed up for at least 12 months after surgical treatment between June 2010 and June 2013 were included in this retrospective cohort study.According to the different internal fixation,the patients were assigned to inverse LISS group [16 males and 8 females;(62.5 ± 12.4)years] and Gamma nail group [17 males and 11 females;(60.4 ± 18.6)years].According to the AO classification,there were 6 patients with A2.2 type,5 A2.3 type,5 A3.1 type,6 A3.2 type and 2 A3.3 type in inverse LISS group,and there were 4 patients with A2.2 type,7 A2.3 type,9 A3.1 type,5 A3.2 type and 3 A3.3 type in Gamma nail group.Opcration time,total blood loss (intraoperaive plus occult blood loss),hospital length of stay,bone healing,time of commencing full weight-beating and complication incidence were compared between the two groups.Harris hip score was recorded postoperatively.Results All patients were followed up for 24-36 months (mean,30.2 months).Operation time in Gamma nail group was shorter than that in inverse LISS group (P < 0.05),while relatively more blood loss was found in Gamma nail group(P <0.05).There were no significant differences in hospital length of stay and bone healing timebetween the two groups (P > 0.05).Patients in Gamma nail groups started earlier full weight-bearing than inverse LISS group (P <0.05).Harris score was (86.1-± 12.4)points in inverse LISS group one year after operation,not significantly different from (83.3 ± 11.2) points in Gamma nail group (P > 0.05).Complication of one patient with coxa vara and one bone nonunion in inverse LISS,showing no significant from one patient with screw breakage and one femoral head osteonecrosis in Gamma nail group (P > 0.05).Conclusions Both techniques are effective in treatment of intertrochanteric fractures combined with lateral wall fractures and achieve similar results in function recovery.But inverse LISS is eccentric fixation,so too early weight-bearing should not be over-emphasized.
