Patients were asked to complete a patient questionnaire (Patient-Rated Wrist Evaluation Score- PRWE)* and a question on their wrist function**

* the PRWE is a self-administered, patient-specific questionnaire that consists of 15 items. It was designed to measure wrist pain and disability in activities of daily living, and consists of two subscales: pain and function. A score of 100 represents the worst functional score, whereas 0 represents no disability

** Patient reported outcome: assessment of fractured wrist comparing to before injury on a scale from 0 to 10, 0 being worst imaginable, and 10 being as good as before the injury.

Race and Ethnicity were not collected from any participant.

As the retrieval of the demographic data was not always possible the number of cases for the weight differs from the total amount of cases.

As the retrieval of the demographic data was not always possible the number of cases for the height differs from the total amount of cases.

As the retrieval of the demographic data was not always possible the number of cases for the body mass index differs from the total amount of cases.

Safety will be assessed by recording and analyzing the incidence and frequency of complications. The complications are classified per ISO 14155 Definitions: Adverse Events (AEs), Serious Adverse Events (SAEs), Adverse Device Effects (ADEs), Serious Adverse Device Effects (SADEs).

In a case the General Wrist Function could not be assessed as the patient is suffering from Kienbock's disease and is experiencing a lot of pain, therefore the General Wrist Function is calculated for 113 cases.

Fracture of ribs and hip due to a car accident

Reduced mobility, as patient unable to use the left thumb which heavily impacts the ability to perform any task with left hand - patient reported this was due to a ruptured tendon as a result of plaster cast

Patient is experiencing ongoing significant pain due to Kienbock's disease

Patient had wrist plate removed due to "rubbing against nerve-screw was pressing against skin". Patient pointed out a small lump on the radial border of wrist which is quite tender and possibilities this may be a screw.

Patient received epidural injection for trapped nerve/shoulder/arm pain

1. Ongoing pain in wrist - described as "mild"
2. Regular ongoing pain in wrist since operation when performing tasks with affected wrist
3. Significant pain when using wrist and unable to straighten ring and little finger also weakness in wrist

Patient said a screw was "loose" according to the x-rays during clinic appointment - has not caused any issues

1. Stiffness and pain causing difficulty moving the hand-removal of used K-wires
2. Shoulder pain and stiffness
3. Stiffness in wrist

Experiences shooting spasm pains down arm and wrist - especially when using wrist a lot during working. Pain is not bad enough to stop subject from doing anything.

2- Patient experiences very occasional sudden shooting pain - no clear cause

Rotator cuff impingement with long head of biceps medialisation. Severe stiffness due to multiple injuries and prolonged reduced mobilization.

1. Patient reported there was a gap between the bones in wrist. Pain when using wrist and a 'clunking'
2. Pain is flaring up from time to time. Very active and pain mostly occurs recently during activities like climbing Nothing to note in X-Rays

1. Patient experiences 'clicking' in wrist when moving with a "mild ache"
2. Patient experiences occasional mild pain when it's cold

Patient experiences intermittent pain in wrist and mentioned experiencing ongoing instability and it has some deformity -There was pre-existing instability of the DRUJ therefore the complication is unrelated to the device.

Patient developed a LRTI post op and was given a course of antibiotics - extended hospital stay

1. Reduced wrist function and occasional pain due to ongoing arthritis
2. Patient developed arthritis in wrist
3. Arthritis in wrist -pain, mostly in cold weather. Post-OP onset
4. Arthritis in fingers- regular ongoing pain in wrist

Patient attributed lower rated wrist function due to "stiff fingers"- unable to make a fist with left hand

1. Fall-no fracture but ligaments in arm/shoulder injured- pain affects wrist function
2. Fall, mobilizing with crutches-numbness in thumb and tip of little finger-reduced finger mobility
3. Patient had a subsequent fall, thumb injured- ongoing pain

1- Patient experienced discomfort and pain following operation. Shooting pain into ring and little finger, reduced grip and trouble rotating wrist

Polytrauma - long hospital stay

Subject experiences aching and some pain depending on the weather - affects subject intermittently

1. Ongoing pain and eventually had metalwork removed
2. Pain caused plate removal
3. Ulna plate fixation failed in osteoporotic bone causing need for revision ulna fixation

Recovery after surgery took longer than the time frame the surgeon gave. Patient struggled to move fingers and wrist significantly post-surgery

Patient experiences significant pain when lifting any heavy object and has ongoing weakness in affected hand/wrist

1. Patient's wrist was still quite painful, causing some difficulty sleeping at night and has minimal range of movement - wrist was slightly swollen, slightly hypersensitive thumb with some occasional pins and needles
2. Pain and discomfort in wrist

1. Slightly reduced ROM-wrist flexion and some resistance when making a tight fist
2. Reduced ROM in wrist
3. Slight reduced range of motion- hand not flat during yoga
4. Stiffness, reduced ROM and some pain
5. Reduced wrist ROM affecting activities

Patient struggles with pain when lifting heavy objects (more than 5kg) and with repeated movements like using a tin opener or using bathroom tissue. Patient avoids these activities.

Patient since operation gets occasional pain and slight reduced ROM, only at it's worse during cold weather. The pain rarely affects the patient.

Patient experiences numbness in thumb, index & middle fingers which is related to the nerve dysfunction

Swollen wrist with a globally reduced range of motion which results to the hand movement stiffness

Pain post operatively leading to prolonged stay. Background of Polymyalgia which can often predispose to pain control issues. Difficult to say if pain from swelling of original fracture of from procedure.

Patient experiences shooting/nerve pain in wrist when completing certain tasks like using a bathroom tissue. Does not occur often but can be really painful

Patient's stitches/wound opened up the day after surgery - bleeding inside the cast. Went t back to hospital to have her wound re-dressed and re-cast.

Plate has not stopped the bones from moving forward

1. Patient experiences tingling sensation when touching the skin over the plate
2. Patient experiences regular nerve pain/twinges, and pins & needles

Patient experiences clicking in wrist when moving and some minor weakness when lifting heavy objects

Patient's operated wrist is thicker than other (non-operated) wrist

Patient is complaining of the plate pinching a nerve in wrist causing issues with thumb (stiffness and poor flexibility)

1. Small amount of loss of power & grip strength
2. Reduced grip strength-doesn't impact activities
3. Reported lower grip strength in affected hand/wrist
4. Reduced strength and infrequent pain-worse/intense when using wrist for certain activities

Patient had delayed discharge due to concurring spinal injuries

Collapse at fracture site resulting in metalwork removal (plate and screws)

Back pain/nerve pain in back that sometimes affects both arms

1. Patient experienced stiffness of wrist (no pain) and irritation cause by the plate

2. Patient experiencing pins & needles in wrist, extending to forearm for the last 1-2 years

1. Patient has ongoing pain/aches in wrist, stiffness and reduced grip strength making majority of activities more difficult
2. Patient gets pain when performing repeated wrist movements, has increased stiffness & reduced ROM when twisting wrist

1. Patient has reduced level of strength in left hand
2. Patient's wrist fatigues quickly and loses strength during use. The patient also experiences regular ongoing pain in wrist
