Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Group A will undertake a novel combination of synergistic wrist-finger exercises within the constraints of a removable splint after ORIF of proximal phalangeal fracture of the finger.
The frequency of these exercises will be 10 completions of the exercise sequence, repeated a minimum of 6 times throughout the waking day.
The duration of the exercise program is 6 weeks.
The mode of administration will be that exercises are taught one-on-one with a Hand Physiotherapist or Occupational Therapist initially, and then practiced on an individual basis unsupervised until the next review appointment, where the program will be checked and reiterated. This will be repeated weekly for 6 weeks.

Eligibility
Key inclusion criteria
All adults (age range: 18- 65 years of age) with finger proximal phalangeal fractures that were stabilised via open reduction internal fixation (with plate and screw fixation or screw fixation alone) at Sydney Hospital Hand Unit are candidates for inclusion in the study. Participants must also have a willingness to give written informed consent and willingness to participate in and comply with the study.
Minimum age
18 Years

65 Years
Gender
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
(1) there was a delay between fracture and surgical fixation greater than two weeks,
(2) the surgical procedure did not achieve stability,
(3) there is the presence of co- morbidities including diabetes and active arthropathy,
(4) there is concomitant tendon or nerve injury, other fracture or vascular injury,
(5) there are cognition problems or poor pain awareness,
(6) there is an inability to attend regular hand therapy follow- up appointments.
(7) patients with a history of a psychological illness or condition such as to interfere with the patient's ability to understand the requirements of the study.

Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Upon return to the hand clinic at Sydney Hospital for their initial post- operative review following open reduction internal fixation of their finger proximal phalanx fracture, all potential participants will be approached by an independent member of the Hand Clinic team who will not be involved in their treatment or in the study. The project will be explained and the option to participate will be offered. Should they agree, signed consent will be collected at this stage and initial baseline measures will be undertaken prior to stratified randomisation. The researcher will not be involved in the recruitment process.
The participant will be enrolled into the study after the informed consent process has been completed and the participant has met all inclusion criteria and none of the exclusion criteria. The participant will receive a study enrolment number and this will be documented in the participant’s medical record and on all study documents.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The participant will be randomised (via stratified randomisation) at initial study visit after they have met the enrolment criteria. At this visit the participant will be randomised to study procedure A (Constrained wrist- finger exercises) or Study procedure B (Unconstrained tendon gliding exercises), and receive a Randomisation Number allocated by Hand Clinic. This number will be from a computer generated sequence.
As standard randomisation alone has the potential to create imbalances on baseline characteristics of treatment groups (Altman et al, 2001), we are electing to use prerandomisation stratification to avert the risk of such imbalances. We intend to use blocking as our form of restriction. We will use this blocking to generate separate randomisation schedules for stratified subsets of participants defined by the severity of injury. Severity of injury is an important prognostic factor following proximal phalanx fracture, and is reflected in the type of fixation required to achieve adequate stability.
Potential participants will be stratified as either a level 1 or level 2 severity. Level 1 severity are those that required plate and screws via a dorsal extensor tendon splitting approach. This is usually because the fracture was significantly displaced or occured within a joint (i.e. more severe injury). Level 2 severity are those that require less bulky fixation via screws alone through a less invasive lateral approach or fixation of fractures not within a joint (i.e. less severe injury). This is usually possible because the fracture is not hugely displaced or lies within the shaft of the bone.

We hope stratified randomisation will be particularly helpful to avert severe imbalances on prognostive factors in this case due to our trial being small, and may improve statistical power and precision (Meinert, 1986).

Summary
Brief summary
The purpose is to investigate whether the type of hand exercises affect short-term outcomes, in particular range of motion of the finger, following surgery to stabilise fractures of the proximal phalanx in the finger. Following surgery, participants will be randomised to one of two groups, where the treatment variable will be type of exercise. All other treatment will be constant between the two groups.
