Despite the current sterile techniques used for all surgeries, infections are occasionally seen following carpal tunnel release. The seriousness and subsequent treatments options will vary depending on the location. Infections can range from very minor ones that are only treated with antibiotics to very major infection requiring a repeat surgery. Furthermore, an infection after this surgery may decrease the chance of successful results through the development of scar tissue and possible stiffness.
If an infection does develop your doctor will discuss the treatment options and expected outcomes with you.
