•Patients will be excluded if they:
•1. Have a digital nerve injury proximal to distal interphalangeal joint. Such patients are excluded because assessment of the distal sensation of the finger is performed by the hand surgical team as these injuries benefit from operative intervention.
•2. Have peripheral neuropathy or vasculopathy. Peripheral neuropathy will confound the assessment of pain of the injection and all pain scores. Vasculopathy will result in reduced blood flow to the digit and may result in increased risk vascular compromise following digital anaesthesia.
•3. Are unwilling or unable to consent. This includes patients with a psychotic illness that would impair their ability to consent and patients with alcohol or drug intoxication.
•4. Have a tendon sheath infection as digital nerve block may promote the spread of the infection
•5. Skin disease such as eczema overlying the injection site
•6. Have an allergy to lignocaine
