Mention a common complication of back surgery.

Infection at the surgical site is a well-documented complication following back surgery. Surgical procedures involve incisions through the skin and underlying tissues, which can introduce bacteria and increase the risk of infection. This complication may manifest with symptoms such as redness, swelling, increased pain, or purulent drainage at the site of the surgery.

Preventive measures are often implemented, such as using sterile techniques during the procedure and prescribing prophylactic antibiotics. Anyone undergoing back surgery should be aware of this risk, as infections can lead to significant setbacks in recovery, potentially requiring further medical intervention, including additional surgeries or extended antibiotic treatment.

In contrast, improved spinal elasticity, enhanced healing time, and reduced pain levels are generally considered positive outcomes of back surgery rather than complications.
