Description of intervention(s) / exposure
Brief Name: Plates or Intramedullary Screws in Metacarpals: POSIM Trial

This study is designed to compare two standard surgical treatments for displaced extra-articular metacarpal fractures: dorsal plating and retrograde intramedullary screw(s). Participants will be randomly assigned to one of these two treatment groups.

The main intervention of interest is the retrograde intramedullary screw fixation, though the trial aims to evaluate the efficacy of both interventions.
The surgeries will be conducted by orthopaedic surgeons, who are not identified by name for this registration, with expertise in hand surgery.

In both treatment options, the expected duration, procedures, anesthesia, post-operative care, and other related elements remain the same. The only variation between the groups is the specific fixation method used, either screws or plates.

Follow-ups will be scheduled to assess the total active motion (TAM) of the involved digits, grip strength, hand function, and pain levels at intervals of 6 weeks, 3, 6, and 12 months after surgery.

To ensure consistency and fidelity to the intervention, an audit of hospital records, surgical procedure documentation, and regular monitoring by a designated clinical trial team will be carried out. This approach ensures adherence to the chosen intervention and allows for accurate reporting and assessment of the study outcomes.

Treatment: Surgery
Comparator / control treatment
The active control treatment for this study will be Dorsal Plating. Both Dorsal Plating and the reference treatment of Intramedullary Screw fixation will be performed under similar conditions. These include the same surgical settings, duration, anesthesia, post-operative care, and follow-ups. Participants will be randomly assigned to receive either Intramedullary Screw fixation or Dorsal Plating. Each of these methods will be executed by a qualified surgical team, consisting of a consultant surgeon, fellow, or SET-accredited registrar. The decision on the operative plan for each participant will be made following consultation with the supervising consultant.

Outcomes
Primary outcome [1] 334489 0
The primary outcome of this study is to evaluate the effectiveness of dorsal plate versus intramedullary screw fixation techniques in regards to post-operative total active motion (TAM) in patients following extra-articular metacarpal fractures. TAM will be assessed using a goniometer, a device used to measure the angle of joint movement, to provide an accurate and standardized measurement of the range of motion in the involved digit at 6 weeks post-surgery.
Timepoint [1] 334489 0
6 weeks post-surgery
Secondary outcome [1] 420836 0
To evaluate dorsal plate verses intramedullary screw(s) fixation techniques regarding post operative total active motion (TAM) in patients following extra-articular metacarpal fractures. TAM will be assessed using a goniometer.
Timepoint [1] 420836 0
3-, 6- and 12-months post-surgery.
Secondary outcome [2] 420837 0
To evaluate dorsal plate verse intramedullary screw(s) fixation techniques regarding post operative grip strength in patient's following extra-articular metacarpal fractures. Grip strength measurements will be performed using a Hydraulic JAMAR Hand Dynamometer, which is the recognised standard of the measurement of grip strength. Measurements will be recorded in kilograms.
Timepoint [2] 420837 0
3, 6, 12 months post-surgery
Secondary outcome [3] 425971 0
The patient-rated outcomes in this study will be assessed using a standardised questionnaire: the Disabilities of the Arm, Shoulder and Hand (DASH) Score. This assessment will be conducted independently to gauge different aspects of the patients' hand functionality and quality of life post-surgery.
Timepoint [3] 425971 0
3, 6, 12 months post-surgery
Secondary outcome [4] 425972 0
Participants' pain levels in the affected finger will be assessed at each follow-up appointment using a Visual Analogue Scale (VAS). Pain will be rated on a 0 to 100 scale, with 0 indicating no pain and 100 indicating extreme pain. This scale provides a subjective but standardized measurement of the pain experienced by the patient.
Timepoint [4] 425972 0
3, 6, 12 months post-surgery
Secondary outcome [5] 430325 0
The MHQ score will be used as another distinct secondary outcome. This questionnaire evaluates overall hand function and quality of life from the patient’s perspective. It offers a comprehensive assessment of how the surgery has impacted the patient's daily life and hand-related activities.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will be concealed through the use of an online randomisation and data storage service - REDCap.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participating patients will be randomised to dorsal plate or IMS fixation using a computer-generated system. Distance randomisation will be performed through an online randomisation and data storage service - REDcap. The medical officer, upon recruiting a patient, will enter the patient's details into REDcap, which will then provide the group allocation.

Statistical methods / analysis
Following completion of data collection, data will be directed exported from REDcap into SPSS or STATA, both of which are available to the research team. Data will be visually inspected for any out-of-range values.
Descriptive data: will be presented as the aggregate value, mean, range, and percentage, using tables and figures as appropriate.
Continuous variables: will be assessed for significance using the appropriate t-test. Significance will be set to P<0.05, with the confidence interval of 95%.
Categorical data: association will be determined using Pearsons Chi2, with a Cramer’s V to assess confidence of association.
The Griffith University or GCHHS biostatistician will be consulted for support or guidance as necessary.
