Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Brief name:
Distal femoral locking plates used for the treatment of distal femoral fractures and applied in two modes: Long working length versus short working length.
Materials:
Titanium distal femoral locking plates will be applied through surgery.
Procedures:
Surgery: Application of locking plates to patients of distal femoral fractures under anaesthesia and tourniquet control through lateral thigh incision in group A(long working length) and group B(short working length)
Who:
The operating surgeon will have minimum of 5 years post graduate experience in Orthopaedics & Traumatology
Mode of delivery:
It will be face to face.All patients with distal femoral fractures will be admitted in hospital in Orthopaedics & Traumatology Unit as soon as they are presented to hospital for treatment.After informed written consent each patient will operated upon individually.
Number of times:
Each patient in each group will be operated upon only once initially.(only one session) The duration of surgery(session) will last for one and half hour to two hours approximately.After surgery each patient will be seen face to face every 4th week for the first three months and then every three months till two years.If any complications of surgery is reported in the follow up visits,it will be dealt with accordingly at that time.
Location:
The intervention(surgery) will be performed on patients in Hospital(Lady Reading Hospital, Peshawar,Pakistan),This hospital is the biggest hospital of the province with a very large catchment area and all patients of long bone fractures are initially brought here for treatment.
personalised
what:
Patients of distal femoral fractures will be divided in two groups and operated upon with distal femoral locking plates applied in long working length or short working length mode.
why:
Variations in the working length of a titanium locking plate affect stiffness and interfragmentary movements of a fracture and its healing.We hypothesize that longer working length of a titanium locking plate has less nonunion and plate breakage rates
when:
As soon as the patients of distal femoral fractures are presented in hospital and they gave informed consent for surgery and participation in study, they will be operated upon.
How this will occur:
All patients of distal femoral fractures meeting the inclusion criteria presenting to hospital for treatment and willing for surgery will be enrollment in the study and will be operated in hospital. All the patients will be randomized into two groups i,e, group A(long working length) and group B(short working length). In the long working length plating all the combi screw holes overlying the fracture or comminution will be left empty plus two combi empty screw holes will be left proximal to the fracture in the intact bone.In the short working length no combi screw holes in the intact bone near the fracture will be left empty.
Intervention code [1] 314570 0
Treatment: Surgery
Comparator / control treatment
Patients with femoral fractures fixed with locking plates in Short working length mode.In the short working length locking plate no combi screw holes in the intact bone near the fracture will be left empty on either side.The treatment will be given to patients face to face in hospital through surgery and only once,The surgery will be performed by an experienced orthopaedics and trauma surgeon with minimum 5 years post graduate experience. After surgery each patient will be seen face to face every 4th week for the first three months and then every three months till two years.If any complications of surgery is reported in the follow up visits,it will be dealt with accordingly at that time.

Outcomes
Primary outcome [1] 320357 0
Bone union will be assessed with xray by observing callus formation and disappearance of fracture lines.
Timepoint [1] 320357 0
8 months post operatively
Secondary outcome [1] 370795 0
infection(Composite secondary outcome)
assessed clinically by recording pain through Visual Analog Scale(VAS) ,swelling thigh measured with a tape and compare with the other normal thigh,discharge from wound site assessed visually and collecting the discharge with a swab on stick, fever recorded with a thermometer and biochemically elevated white cell count,raised ESR,raised CRP.
Timepoint [1] 370795 0
at follow up visit every 4th week for the first three months and then every three months till 8 months

Safety/efficacy
Statistical methods / analysis
Fractures of the distal femur accounts for 4% to 6% of all femur fractures .The sample size will be 76 with 80% power of the test and 95% confidence interval. Each group A(long working length) and group B(short working length) will have 38 patients based upon 16.6% non union in short working length plate and 0.7% non union in short working length plate. The sampling technique will be non probability convenient sampling.
Statistical analysis will be done by using SPSS version 20. Categorical variables like gender will be represented as frequency and percentage while mean±SD will be calculated for numerical variables like age.The significance of non union and implant failure between the two groups will be assessed with chi-square test. P value will be considered significant if < 0.05.

Summary
Brief summary
All the patients with distal femoral fractures be randomized into two groups
i,e, group A(long working length) and group B(short working length) and operated.In the long working length plating all the combi screw holes overlying the fracture or comminution will be left empty plus two combi empty screw holes will be left proximal to the fracture in the intact bone.In the short working length no combi screw holes in the intact bone near the fracture on either will be left empty.We hypothesize that longer working length of a titanium locking plate has less nonunion and plate breakage rates.
