BACKGROUND: Carpal tunnel syndrome (CTS) is the most common peripheral entrapment
neuropathy. Limited incision techniques for carpal tunnel release are gaining
popularity. The main advantages of these techniques are less scar load, less
pillar pain, shorter recovery, and return-to-work time. However, the completeness
of release, and risk of neurovascular injury are always a concern. We devised a
method of limited incision release with two mini-incisions and use of nasal
speculum and a probe. We aimed to evaluate the clinical and neurological outcome
of this technique. MATERIALS AND METHODS: Twenty seven cases (9 male and 18
female, age 28-56 years) of isolated CTS cases were enrolled in the study. A
total of 33 hands (six bilateral) underwent limited incision carpal tunnel
release. In this study, two mini-incisions were used and release was done with
the help of nasal speculum. Evaluation preoperatively and in 6 months and at
1-year postoperatively was done, namely, (a) clinical status examination, (b)
motor testing using grip and pinch dynamometer, and (c) neurological outcome
measure using nerve conduction study. RESULTS: All the patients had good clinical
and neurological outcome with no recurrence during followup. The first symptom to
get relieved was night pains, with a mean of 4.5 days (range 2-14 days). Compared
to pain, improvement of sensory symptoms was delayed; the mean duration was 42.8
days (range 30-90 days). Scar tenderness was present only for a mean duration of
9 days (range 7-21 days). The mean duration for patients to resume their daily
activities was12 days (range 7-28 days) and to work was 32 days (range 21-90
days). The hand grip showed mean values of 45.12 ± 16.16 g/mm(2) preoperatively,
62.45 ± 18.86 g/mm(2) at 6 months postoperatively, and 74.87 ± 20.35 g/mm(2) at
1-year postoperatively. The key pinch showed mean values of 11.27 ± 3.51 g/mm(2)
preoperatively, 20.181 ± 3.94 g/mm(2) at 6 months postoperatively, and 27.96 ±
94.42 g/mm(2) at 1-year postoperatively. The tip pinch showed mean values of 8.88
± 2.39 g/mm(2) preoperatively, 15.393 ± 3.25 g/mm(2) at 6 months postoperatively,
and 19.27 ± 4.81 g/mm(2) at 1-year postoperatively. The palmar pinch showed mean
values of 14.42 ± 2.92 g/mm(2) preoperatively, 19.303 ± 3.62 g/mm(2) at 6 months
postoperatively, and 22.97 ± 4.08 g/mm(2) at 1-year postoperatively. CONCLUSION:
Limited incision carpal tunnel release can be considered a feasible alternative
to traditional open release and endoscopic release.
