The treatments for non-deficit forms of carpal tunnel
syndrome (CTS) are corticoid infiltration and/or a nighttime immobilization
brace. Surgical treatment, which includes sectioning the retinaculum of the
flexors (retinaculotomy), is indicated in cases of resistance to conservative
treatment in deficit forms or, more frequently, in acute forms. In minimally
invasive techniques (endoscopy and mini-open), and even though the learning
curve is longer, it seems that functional recovery occurs earlier than in the
classical surgery, but with identical long-term results. The choice depends on
the surgeon, patient, severity, etiology and availability of material. The
results are satisfactory in close to 90% of the cases. Recovery of strength
requires four to six months after regression of the pain of pillar pain type.
This surgery has the reputation of being benign and has a complication rate of
0.2–0.5%.
