Scientific titleBotulinum toxin: an adjunct in limb reconstruction - Can it reduce pain and joint complications in the lengthening phase?
Study acronymBotox
Study objectivesThe surgery to correct leg and foot deformities in children is a lengthy, and sometimes, difficult procedure. Metal frames are attached to the leg and/or foot and over a period of time the frame is manipulated to obtain the corrected position. During this period the muscles and skin become very tight which causes pain and may pull the joint out of position. When this happens it is sometimes necessary to stop the treatment before the best position is obtained. This means that not only is the child left with an inadequate result but that further surgery is required in the future. If the tension could be removed whilst the treatment is underway this would reduce the pain, the possibility of joint damage and potentially allow a more satisfactory to be obtained without the need for further surgery.

Botulinum toxin or Botox®, as it is commonly called, has the potential to temporarily reduce the tension in the muscles without causing permanent damage.
Ethics approval(s)An application has been submitted to the North Sheffield Research Ethics Office. Approval pending as of 18/02/2008.
Health condition(s) or problem(s) studiedLimb reconstruction surgery
InterventionPatients and the researcher collecting data will be blinded to the allocation of treatment.

Intervention group: Botulinum toxin intramuscular injections, 4 units per kg body weight
Control group: Saline injections
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Specified
Drug / device / biological / vaccine name(s)Botulinum toxin (Botox®)
Primary outcome measurePain levels using a visual analogue scale validated at the Sheffield Children's Hospital. Following discharge from hospital, patients will be asked to continue recording pain level three times a day for 18 month or until discharged i.e. end of episode, which ever is first.
Secondary outcome measures1. Range of movement in affected joints measured by a goniometre, recorded at each clinic visit until one month from the end of lengthening
2. Walking measured using a pedometer, recorded at each clinic visit until one month from the end of lengthening
3. Scores of the Child Health Questionnaire and the Pediatric Outcome Data Collection Instrument, administered pre-operatively, one month post-lengthening completion and one year from surgery
Overall study start date01/04/2008
Completion date01/04/2010
Reason abandoned (if study stopped)Lack of funding/sponsorship

Editorial Notes

30/01/2020: Following scientific peer review of the protocol the feedback received raised ethical issues on the basis that a larger, similar study was being conducted in Canada and on this basis it was recommended that the study does not receive additional funding. Following this advice the decision was taken not to proceed with the trial. No participants have been recruited therefore there are no adverse implications for this decision.
10/09/2019: ClinicalTrials.gov number added.
05/04/2013: Trial status amended to 'stopped' due to notification that the study was withdrawn.
