Conditions
Digital Nerve Injury

Procedure: Non-operative treatment

Brief Summary

Nerve injury in the fingers is a common injury and affects people of all ages. The treatment usually offered to patients is surgery and various types of rehabilitation. There is a lack of knowledge and research on how these injuries should be treated in the best way and how well sensory function can be restored after an injury. In this research project, we will investigate results after treatment for digital nerve injuries by entailing a randomised controlled trial allocating patients with isolated digital nerve injuries to either surgical repair or non-operative treatment in a cast. Primary outcome is digital nerve function as measured by 2-points discrimination at 1 year after treatment. Secondary outcomes include finger mobility, dexterity, handfunction, occurence of pain and anxiety and time on sick leave.

Detailed Description

Patients over the age of 20 with an acute traumatic isolated digital nerve injury to any of the fingers and not in the thumb will be investigated for inclusion in the study. After informed written consent a sealed envelope randomisation will allocate patients to treatment with either surgical exposure and epineural suture or non-operative treatment in a cast. Due to the nature of treatment arms the allocation will not be blinded. Clinical follow-up and investigation of primary and secondary outcomes will be conducted at 3 weeks, 3 months, 6 months and 1 year after inclusion.

Arm && Interventions
GroupInterventionDescription
Epineural sutureEpineural sutureThe injured digital nerve is exposed during a surgical intervention and sutured with 2 or three epineural sutures 8.0 or 9.0 synthetic monofilament non-resorbable suture. Postoperative treatment includes 3 weeks in a plaster cast followed by rehabilitation.
Non-operative treatmentNon-operative treatmentThe injured digital nerve is not surgically exposed. The skin is closed over the injury site and the finger is protected in a plaster cast for three weeks followed by rehabilitation.
Primary Outcome Measures
NameTimeMethod
Static two points discrimination (S2PD)one year after injury

a static two points discrimination test performed by an occupational therapist of the injured finger

Secondary Outcome Measures
NameTimeMethod
Semmes-Weinstein monofilament test3 and 6 months and 1 year

Discriminatory sensory function as measured by Semmes-Weinstein monofilament test

Mini Sollerman test3 and 6 months and 1 year

Hand function as measured by the Mini Sollerman test

Quick-DASH3 and 6 months and 1 year

Patient Rated Outcome measure (PROM) for hand function as measured by the quick-DASH (Disability of the Arm, Shoulder and Hand). 11 items with 5-level Likert scales measures upper limb function. The scale ranges from 0 - 100 and 0 is the lowest possible disability.

Pain catastrophising scale, (PCS)at inclusion

Pain catastrophising scale, (PCS) measures 13 items on a 5 points Likert scale. Higher scores represent high degree of pain catastrophising scale, (PCS).

Wait for surgery3 weeks

The number of days that have passed from the day of injury to the day of surgery are reported

Active range of motion3 and 6 months and 1 year

Range of motion of the injured finger (sum of MCP + PIP + DIP joint motion measured in degrees)

Ratio between S2PD in injured finger and S2PD in uninjured contralateral finger3 and 6 months and 1 year

Ratio between S2PD in injured finger and S2PD in uninjured contralateral finger

Grip strength3 and 6 months and 1 year

Grip strength of injured and non-injured hand as measured by Jamar dynamometer

HQ-83 and 6 months and 1 year

Patient Rated Outcome measure (PROM) for hand function as measured by the HQ-8 (Eight item HAKIR questionnaire)

Anxiety and depressionat inclusion

Psychologic wellbeing as measured by Hospital Anxiety and Depression scale (HAD) (PCS)

Neuropathic pain3 and 6 months and 1 year

Occurrence of neuropathic pain as measured by Doleur Neuropathic 4 questions (DN4). 4 aspects of neuropathic pain are evaluated by 10 questions, with higher scores representing a worse state.

Sick leave time1 year

Days of absence from work

Time in operating theatreday of surgery

Time in operating theatre is measured in minutes
