Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Oral ibuprofen 400 mg three times a day for three weeks post flexor tendon repair in interventional arm
Intervention code [1] 299567 0
Treatment: Drugs
Comparator / control treatment
Control arm (paracetamol) will receive 1000 mg paracetamol three times a day for three weeks as a pain killer and will act as a active control.
(It is considered a active control group as paracetamol has minimal anti-inflammatory activity and is used as centrally acting anti-pyretic and pain killer. Ibuprofen will be beneficial due to local anti-inflammatory activity through enzyme inhibition.)
Control group
Active

Outcomes
Primary outcome [1] 303893 0
Range of motion assessment using Strickland criteria for PIPJ and DIPJ with contralateral hand as normal. If contralateral hand is not normal, 175 degrees ROM for both joints is considered the normal value. The sum of the degrees of active PIPJ and DIPJ flexion less the degrees from full extension is taken as motion range. Function Grade assessment is reported as: Excellent 85-100%, Good 70-84%, Fair 50-69%, Poor <50% (expressed in percentage of normal).
Timepoint [1] 303893 0
6 weeks and 12 weeks (primary endpoint) after flexor tendon repair
Primary outcome [2] 303927 0
Total Active Motion under this criteria is calculated in a similar manner as the range of motion under Strickland criteria, but also includes the MCPJ range of motion: Active Range of Motion (AROM) from MCPJ, PIPJ and DIPJ with contralateral as normal, if contralateral hand is normal. If contralateral hand is not normal, 260 degrees TAM for all three joints is considered the normal value. The sum of the degrees of active MCPJ, PIPJ and DIPJ flexion less the degrees from full extension is taken as motion range. Function grade assessment is reported as: Excellent 100%, Good >75%, fair >50%, Poor <50% (expressed in percentage of normal).

Allocation will be concealed using serial numbers and opaque envelopes/containers
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The ralloc command of the Stata statistical program will be used to create a Block Randomisation. The randomisation list (Participant Number, Ibuprofen or Paracetamol) will be forwarded to the Pharmacy where the appropriate drug sufficient for 3 weeks use will be packaged along with dosing instructions and the packages labeled with the name of the trial and the Participant Number. Participants will be provided with consecutive Participant Numbers upon consent.

Efficacy
Statistical methods / analysis
We expect to achieve 85% of normal range of motion for the finger joints in intervention arm at the end of 12 weeks. We hypothesize that finger movement in the ibuprofen group will be better than the control arm. In the clinical setting, this means a difference of about 35 degrees of the total movement of the finger. The number has been derived from prior studies where a difference of 35 degrees moves a patient from the good to the excellent category.

This study is designed to detect a difference of 35 degrees in the PIPJ+DIPJ ROM between control arm and ibuprofen (interventional) arm where the mean angle of control arm is 114 degrees and the ibuprofen arm is 149 degrees. The difference is considered the smallest clinically relevant difference. Based on using a two-sample t-test with a SD of 45 in each group, for a type 1 error (alpha) of 0.05 and a power of 90% we will require a total of 60 participants, 30 in each arm. Considering 10% withdrawal rate, sample size will be kept at 66 participants, 33 in each arm.

Summary
Brief summary
Title: A double blind randomised controlled trial assessing the effect of oral ibuprofen on outcome of flexor tendon repairs

Short Title: Ibuprofen Flexor Tendon Trial (IFTT)

Design: Double Blind Randomised Controlled Trial

Hospital/s: Gold Coast Hospital and Health Service

Study Question: Does oral ibuprofen influence outcome in patients post flexor tendon repair?

Primary purpose of the study: This study has been designed to assess the effect of using oral ibuprofen after repair of hand flexor tendons on function and final outcome of hand . Study hypothesis is that use of oral ibuprofen after flexor tendon repair will result in improved outcome in comparison to when ibuprofen is not given.Ibuprofen should also result in decreased swelling of fingers.

Many work hours will be saved and quality of life will be improved in flexor tendon repair patients if the study hypothesis is found to be true and a cheap and easily available drug like ibuprofen can reduce financial burden of these injuries on society and community.
