Objectives/Interrogation: Fingertip injuries are common among the young working group of people in a developing country posing a great concern.

Sensation in the flap is imperative to the proper functioning of the reconstructed fingertip. The study conducted to observe the way to return of two-point tactile discrimination in different stages and conditions over the flap after division is a method of identifying adequate functional re-innervation of the flap.

Methods: A prospective observational study to measure the changes during the recovery of two-point tactile discrimination (TPTD) over the dorsal cross finger flap was carried out for a period of 6 months after flap division for each case. TPTD was measured in the dorsum before flap elevation (donor control) and from the corresponding opposite fingertip (control). Then TPTDs were noted from the day of flap division, 7th POD, 15th POD and thereafter monthly up to six months. Data were analyzed and compared on those days in-relation to age, sex, hand dominance, time to repair after injury and smoking.

Results and Conclusions: In this study, it was shown that the mean TPTD on the dorsum of the middle phalanx of the flap donor site (Donor Control) was 5.31 ± 0.79 mm and on the corresponding opposite fingertip (Control) was 2.79 ± 0.78 mm.

In the 1st follow-up on the 15th POD following flap division, the mean TPTD was 15.70 ± 1.31 mm, on 30th POD was 14.66 ± 1.14 mm, on 60th POD 13.74 ± 1.00 mm, on 3 months 13.10 ± 1.12, 4th & 5th months 11.87 ± 1.01 & 09.25 ± 1.09 respectably and at 6th months was 07.70 ± 0.92 mm.

The improvement was rapid between the 4th & 6th months where the mean improvement was 4.17 mm - the most significant improvement. It had been evident, TPTD on 6th months (7.7 mm) was reached just below the protective sensation cut off value of 8 mm in 83.4% cases. But no statistically significant differences were found in the two comparing age groups (< 30 years and >30 years). In the same time, no statistically significant differences were found while comparing between sex, reconstruction time after injury, type of injury, hand dominance and even on smoking.

So, the cross finger flap for fingertip injury reconstruction is a good option for a resource-poor developing country.
