Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The dependent variable (intervention) will be 100 units of Botulinum toxin reconstituted with 2 cc of Normal Saline, introduced using a one-off intramuscular injection into the bifurcation of the biceps in the upper arm and the brachialis at the level of the elbow joint, under ultrasound guidance by the anesthetist postoperatively, at the time when the anesthetist inserts a pain catheter for postoperative pain control for patients undergoing arthroscopic osteocapsular release for elbow contractures. As this trial aims compare the effect of a one-off administration of the intervention (botulinum toxin reconstituted with normal saline) compared to a one-off administration of a placebo (normal saline only) pre-surgery, adherence to the intervention is not applicable.
All other processes of arthroscopic osteocapsular release for elbow contractures will occur as per usual standard care.

Treatment: Drugs
Comparator / control treatment
The control (placebo) will be 2 cc of Normal Saline, in a one-off intramuscular injection into the bifurcation of the biceps in the upper arm and the brachialis at the level of the elbow joint, under ultrasound guidance by the anesthetist postoperatively, at the time when the anesthetist inserts a pain catheter for postoperative pain control. for patients undergoing arthroscopic osteocapsular release for elbow contractures.
Control group
Placebo

Outcomes
Primary outcome [1] 332978 0
Elbow flexion and extension range of motion will be assessed by a blinded member of the study team, who will take photographs of the elbow in maximal active flexion and maximal active extension from the lateral (side) view.
Computer-based software will then be used to assess the range of motion in and flexion-extension.
Timepoint [1] 332978 0
Preoperatively, and at 3, 6, and 12 months postoperatively
Primary outcome [2] 332979 0
Elbow supination and pronation range of motion will be assessed by a blinded member of the study team, who will take photographs of the patient from the anterior (front) view, with the patient holding straight markers in both hands in maximal active pronation and maximal active supination.
Computer-based software will then be used to assess the range of motion in and pronation-supination.

Summary
Brief summary
This pilot study aims to compare patient-rated outcomes and range of motion between patients who undergo surgical stiff elbow release, treated with an injection of botulinum toxin (botox) pre-surgery vs placebo.

We hypothesized that the injection of botox into the biceps and brachialis immediately before surgery may result in greater range of motion (less stiffness) following surgical release.
