Hernia repair isn't just about placing a mesh – it's about keeping it there securely, safely, and with minimal long-term discomfort. The choice of fixation device matters more than you might think.

HISTORY / ORIGIN

The journey of hernia repair is a story of continuous innovation. The first surgical inguinal hernia repair was reported as early as 1716. However, the modern era began in 1958 when Usher performed the first mesh repair. He introduced the first polypropylene mesh in 1968 as a method to achieve tension‑free hernia repair. The term "tension‑free" hernioplasty was later popularized by Lichtenstein and colleagues in 1986.

But a mesh alone isn't enough – it needs to be fixed in place. Tack fixation has been applied since the introduction of laparoscopic inguinal and ventral hernia repair in the late 1980s and early 1990s. Initially, surgeons used permanent metallic tacks. Over time, concerns about chronic pain and other complications from permanent implants drove the development of absorbable fixation devices. Today, both permanent and absorbable options are available, and the choice depends on the patient's anatomy, risk factors, and the surgeon's preference.

TYPES OF HERNIA FIXATION DEVICES

Hernia fixation devices fall into two broad categories: penetrating and non‑penetrating.

Penetrating Fixation Devices physically pierce the tissue to anchor the mesh. These include:

Tacks – Small, screw‑like devices that come in permanent (e.g., Protack™ helical titanium tacks) and absorbable variants (e.g., AbsorbaTack™, Permasorb™, SorbaFix™, Securestrap™).

Staples – Permanent titanium staples.

Sutures – Can be either permanent or absorbable.

Non‑Penetrating Fixation Devices secure the mesh without piercing the tissue:

Self‑fixating mesh – Has an adhesive side made of microgrips or adhesive material.

Glue / Sealants – Includes cyanoacrylate glue and fibrin sealant.

MATERIALS / KEY FEATURES

What are these devices made of, and what makes them special?

Permanent tacks – Typically made of titanium. They provide greater fixation strength compared to absorbable devices. However, they remain in the body permanently and have been associated with serious adverse events, including dense adhesion formation and erosion into hollow organs.

Absorbable tacks – Made from synthetic bioabsorbable polymers like polylactic acid or polyglycolic acid derivatives. They degrade over time – typically in less than 6 months for amorphous co‑polymers – eliminating the risk of permanent foreign bodies.

Screw‑type fixation devices – Novel designs that provide adequate fixation with decreased adhesion formation compared to traditional titanium tacks. One study found that both absorbable and permanent screw‑type devices provided adequate fixation with significantly less tenacious adhesions than titanium tacks.

BENEFITS / WHY CHOOSE PERMANENT OR ABSORBABLE FIXATION

✅ Permanent devices offer superior strength – Titanium tacks have higher pull‑off forces than absorbable alternatives, making them ideal for large hernias or patients with high intra‑abdominal pressure.

✅ Absorbable devices reduce long‑term risks – As they dissolve, they leave no permanent foreign material, potentially reducing the risk of chronic pain, erosion, and adhesion formation.

✅ Comparable clinical outcomes – Studies show that mesh fixation with permanent tacks does not appear to increase the risk of chronic groin pain compared to absorbable tacks. In ventral hernia repair, no significant differences were found in postoperative pain, quality of life, or recurrence rates between permanent tacks, absorbable tacks, and synthetic glue.

✅ Non‑penetrating options minimize tissue trauma – Glue and self‑fixating mesh avoid piercing tissue altogether, which may reduce nerve irritation and acute pain.

✅ Absorbable meshes may reduce chronic pain – Some studies suggest patients with absorbable meshes experience less chronic pain compared to permanent meshes, without an increased risk of recurrence.

CARE TIPS / USAGE TIPS

The first two weeks are critical – This is when the mesh begins to integrate with your tissue. Follow your surgeon's activity restrictions strictly.

Avoid heavy lifting – For 4–8 weeks after surgery, avoid lifting anything heavier than 20 lbs (approximately 9 kg).

Reduce abdominal pressure – For at least 3 months, avoid activities that strain your abdomen, such as heavy lifting, long‑term coughing, constipation, smoking, or intense workouts.

Keep the wound clean – Clean the suture site once a day and apply clean gauze. You can shower about 36 hours after surgery.

Full integration takes time – Complete mesh integration takes around six months. Be patient with your recovery.

Listen to your body – If you experience unusual pain, redness, swelling, or fever, contact your surgeon immediately.
