Worked example
Fictional case: Mr. A.T., 19 years, painful right great toe for 3 months, lateral nail fold with granulation tissue and discharge (stage III), one previous total nail avulsion 8 months ago, not diabetic.
Case details
Date: 22/07/2026. Elective, day care. Minor OT.
Block given 10:05. Tourniquet on 10:12. Tourniquet off 10:30. Procedure ended 10:32.
Surgeon: Dr A. (1st-year resident, General Surgery). Supervising: Dr B. (senior resident), present.
No anaesthetist (local anaesthesia by surgeon). Nurse: Sr C.
Indication and pre-op
Indication: stage III ingrowing toenail, right great toe, lateral nail fold, recurrent after one total avulsion.
Not diabetic. Dorsalis pedis and posterior tibial pulses felt. No anticoagulants.
Consent: right great toe lateral partial nail avulsion with phenol matricectomy. Risk of regrowth, oozing for some weeks and narrower nail explained in Hindi.
Side marked. WHO checklist done. No antibiotic prophylaxis.
Anaesthesia and position
Supine, right foot at the end of the table. Toe and forefoot painted with povidone-iodine and draped.
Digital H-block of right great toe with plain lignocaine (no adrenaline), 5 ml in total.
Rubber drain tourniquet at the base of the toe at 10:12.
Procedure
Findings: granulation tissue over the lateral nail fold with a little pus. Sharp nail spicule pressing into the lateral fold. Medial fold normal.
Lateral one-fourth of the nail lifted off the nail bed with a flat elevator. Nail cut lengthwise with straight scissors up to the proximal end under the eponychium.
Nail strip removed by twisting towards the rest of the nail. Checked: complete, with the root.
Granulation tissue scraped away with a curette. Pus swab sent for culture.
Antibiotic gel placed on the skin of the nail fold. Cotton applicator with 88% phenol placed in the lateral nail groove under the eponychium and rotated for 30 seconds, then 3 more applications of 30 seconds (4 applications, 2 minutes in total). Field dry.
Phenol diluted with 70% isopropyl alcohol.
Closure
No sutures. Antibiotic ointment without neomycin, non-adherent gauze and light toe dressing.
Tourniquet removed at 10:30. Toe pink, capillary refill normal.
End of procedure
Blood loss minimal. Nail strip discarded. Pus swab sent for culture and sensitivity.
Instrument count correct.
No complications. Sent home after 30 minutes, walking, with written instructions.
Post-op orders
Keep the foot raised for 48 hours. Wear an open sandal.
Tab paracetamol 500 mg, 2 tablets 6-hourly when needed, not more than 8 tablets in 24 hours.
No oral antibiotic.
Dressing change on day 3 in OPD: the treated area will look dark and burnt, this is expected.
Warm water soaks twice a day after the first dressing. Oozing may last 3 to 6 weeks.
Cut the nail straight across in future. Review in 1 week.

Must document for this operation
- Toe, side and nail fold (medial or lateral) treated. Wrong-side surgery on a toe is easy to do and hard to defend, the next doctor also needs to know which edge was ablated.
- Exact operation: avulsion only, or avulsion with matrix ablation, and the method. Recurrence rates differ widely between these, and the next surgeon plans the repeat procedure from this.
- Phenol strength, number and length of applications, and how it was neutralised. If the fold is burnt or the nail regrows, the dose of phenol used is the first thing checked.
- Tourniquet type and the time it was on and off. A forgotten toe tourniquet can cause toe loss, recording removal shows it was checked.
- Diabetes and foot pulses. Poor healing in these patients needs closer follow-up and may point to infection of bone.
- Local anaesthetic drug, with no adrenaline, and volume. Needed if the toe becomes pale or numbness lasts long.
Common mistakes in these notes
- Writing 'ingrown toenail removed' without side, nail fold or matrix treatment.
- Not recording tourniquet removal.
- Leaving out phenol strength and time.
- Not documenting that the patient was told about the dark, oozing wound after phenol.
- Giving routine oral antibiotics without a written reason.
Indian practice and paperwork
- Mark the operated toe and complete the checklist even for a minor OT case. NABH expects measures to prevent wrong site and wrong surgery. (NABH 5th ed., COP.14(d))
- Explain the risks in a language the patient understands and record that it was done. (NABH 5th ed., PRE.4(c))
- The operation note must be complete before the patient is sent out of the procedure area. (NABH 5th ed., COP.14(e))
