ABSTRACT
Objective: Aim of current study is to compare the
outcomes between closed vs open interlocking nail among patients had femur
shaft fracture.
Study Design:Retrospective cohort study
Place and Duration:Orthopedics department of Mardan
Medical Complex and Muhammad Medical College and Hospital, Mirpurkhas during
the period from 16th June 2020 to 15th July 2021.
Methods:One hundred and twenty eight patients with
ages 25-70 years were included in this study. All the patients had femoral
shaft fracture. Patients’ age, sex, body mass index and cause of fracture was
calculated after taking informed written consent. Included patients were
equally divided in two groups. Group O received open interlocking nail and closed
interlocking nail technique was used in group P group. Post-operatively radiological
and surgical outcomes among both groups were assessed and compared in terms of
union, non-union and delayed union. Prevalence of infection among both groups was
also calculated. Flynn’s criteria were used to assessfunctional outcomes. We
used SPSS 23.0 edition to analyze all of the data.
Results:Majority of the cases were males 80 (62.5%)
and 48 (37.5%) were females. There was no any significantly difference among both
groups related to age and body mass index. High impact of collision was the
most common cause found in 75 (58.6%) followed by RTA 35 (27.3%) and fall found
in 18 (14.1%) cases. Mean duration of surgery in group O was 92.34±5.23 minutes
and in group P was 62.12±3.33 minutes. Mean union time in closed group was
lower 19.14±5.45 weeks as compared to open group 28.7±6.19 weeks. Frequency of
union in group P was higher among 64 (96.9%) as compared to group O 52 (81.3%)
cases. Delayed union in group O found among 14 (21.9%) cases and in group P was
among 7 (10.9%) cases. According to Flynn’s criteria, closed interlocking nail
showed significantly excellent and good results with pp value <0.05 as
compared to open technique. Rate of complications were also lower in closed
group with p value <0.05.
Conclusion: In this research we concluded that closed
interlocking nail for femur shaft was effective and useful as compared to open
interlocking nail in terms of good radiological and functional outcomes. Except
this, post-operative complications were also noticed lower in patients who
received closed interlocking nail.
