Arthroscopic Midcarpal Wrist Arthrodesis: Clinical and Functional Outcomes

Study Overview
=================
Brief Summary
-----------------
All cases of midcarpal wrist arthritis treated surgically with arthroscopic partial wrist fusion with cannulated screws from January 2015 to December 2017 will be reviewed. The union rate and time to union will be recorded following the standard radiological postoperative control. Wrist assessments performed pre- and postoperative regarding strength, range of motion and pain will be analysed. Complications will be recorded as well. Participants will be recruited for wrist assessment. They will be asked to fill out questionnaires about the functional result related to their quality of life.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Wrist range of motion after surgery | Extension , Flexion, Radial and ulnar deviation, Pronation , Supination | 5 minutes | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Hand strength after surgery | Strength measurement in kilos (Kg) with Jamar Dynamometer placed in Scale 2. Three consecutive trials will be executed, the best result (higher strength in kilos) will be registered. | 2 minutes | 
| Pain assessment in weight bearing (Visual analogue scale, VAS) | The patients will be asked to evaluate the pain in the wrist by full weight bearing, according to visual analogue scale (VAS 0-10, 0 means no pain, 10 means maximum pain) | 1 minute | 
| Function assessment through DASH (The disabilities of the arm, shoulder, hand) questionnaire | This questionnaire asks about patient's symptoms as well as their ability to perform certain activities in the last week. The DASH Outcome Measure is scored in two components: the disability/symptom section (30 items, scored 1-5) and the optional high performance Sport/Music or Work section (4 items, scored 1-5). The response to the first 30 items of the DASH are added to form the raw, or actual, score. A minimum score is 30; a maximum is 150.The raw score is then transformed to a zero-to-100 scale with zero reflecting no disability (good function) and 100 reflecting maximum disability. The maximum score of the second section is 20 with a minimum of 4. The range of scores is therefore 16. This score is also transformed to a zero-to-100 scale with lower scores reflecting minimal disability, and higher scores reflecting more disability. | 5 minutes |
