Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
1. hand based orthosis - which is a custom molded thermoplastic splint commonly used for the management of hand and wrist fractures
2. buddy strapping - alternatively known as neighbour strapping, consisting of velcro fabric used commonly to keep one finger strapped to the adjacent finger for support

Hand based orthosis group will be fitted with a custom-moulded thermoplastic hand splint, which will hold the 4th and 5th knuckles in a 70 degrees flexed position, leaving the finger joints free. The orthosis will be secured to the hand using three Velcro straps. Orthosis will be fitted at the time of inclusion. Orthosis group will be instructed to remove orthosis for light functional activities, from the 3 week visit, and discard the orthosis at 5 weeks.
Buddy strapping group will be fitted with two soft fabric and Velcro buddy straps, which will be used to splint the fifth finger to the fourth finger. Buddy strap will be fitted at the time of inclusion. Buddy strap group will be instructed to commence light functional activity as tolerated. Participants will be instructed to wear buddy straps daily for 5 weeks.
Both groups will be instructed to remove their device for skin hygiene daily.
Study interventions will be performed by Physiotherapists and Occupational Therapists.
All participants will be followed for six weeks. Clinical assessments will occur at the time of inclusion, one week, three weeks and six weeks. Each participant will see their treating physiotherapist or occupational therapist first to check device fit, and to monitor compliance with the device. Compliance will be monitored by asking the participant if they have been wearing the device. The therapist will then remove the device to allow blinded assessment by a research assistant (Physiotherapist or Occupational therapist).
Each intervention will take place in the hand therapy treatment room of the Westmead Hospital Allied Health Department; will be delivered face to face and will be 30 minutes in duration.

Eligibility
Key inclusion criteria
Adults who present to Westmead Hospital with a fracture of the fifth metacarpal neck, and who have been assessed by medical staff as suitable for non-operative treatment, will be included in the study. Inclusion Criteria will be: Volar angulation of fracture up to 70 degrees, as measured from the lateral x-ray; and no fracture rotation. To assess rotation, the referrer will compare the affected and contralateral hands. Normally, all fingers point to scaphoid tubercle, and deviation from this alignment may indicate a rotated fracture fragment
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Children and people with an intellectual or mental impairment have been excluded from this research study because of their potential inability to provide written and informed consent. This group may also be unable to understand and actively participate in the treatment protocol.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
sealed opaque envelopes
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomised blocks of four by gender
Two envelopes will be used. One for male participants, one for female participants. Each envelope will contain four smaller sealed opaque envelopes: 2x treatment A and 2x treatment B. Sealed envelopes will be randomly allocated until exhausted and then replaced with an additional block of four. Participants will be numbered sequentially.

Efficacy
Statistical methods / analysis
Based on a difference of 16 points in the QuickDASH, the sample size of 50 patients per treatment group was calculated with a power (1-ß) of 80 percent and a type I error (a) of 5 percent. A total of 110 patients will be recruited, to allow for a 10% drop-out rate.
Descriptive statistics will be used to analyse the demographic data
2 group unpaired t test will be used to analyse numerical data
Chi-square test will be used to analyse categorical data
Data analysis will be carried out according to the intention-to-treat principle.

Reason for early stopping/withdrawal
Participant recruitment difficulties
Other reasons/comments
Other reasons
Slower than anticipated recruitment prompted interim blinded statistical analysis of data, which demonstrated no significant difference between groups for primary or secondary outcome measures and no likelihood of achieving significance by continuing to recruit to the proposed number of participants.
