Indications for non-absorbable deep suturing of non-skin tissues include which of the following?

• A. Skin closure
• B. Basic mucosal closure
• C. Subcutaneous fat closure
• D. Tendon repair

Answer: (D)

Tissues that endure ongoing mechanical load during healing need long-lasting support, so non-absorbable sutures are chosen for deep layers. Tendon repairs, in particular, require durable, persistent strength to keep the tendon ends approximated while new collagen forms and the tissue regains functional strength. If absorbable sutures were used, they could lose their holding power before healing is complete, risking gapping or rupture during rehabilitation. In contrast, deeper tissues like subcutaneous fat or mucosa don’t bear high, sustained loads and are typically closed with absorbable material to minimize long-term foreign body presence. Therefore, non-absorbable deep suturing is indicated for tendon repair.
