Summary
Immediate pain-free mobilization after flexor tendon surgery in Zone II is achievable. This technique involves instilling bupivacaine, a local anesthetic, along the tendon sheath to reduce post-operative pain.
Area of Science:
- Orthopedic surgery
- Pain management
- Hand surgery
Background:
- Zone II flexor tendon injuries often involve complex tenolysis or tenosynovectomy procedures.
- Post-operative pain and stiffness can significantly impede early mobilization, potentially leading to adhesions and reduced functional outcomes.
Purpose of the Study:
- To present a novel method for achieving immediate, pain-free mobilization following Zone II flexor tendon surgery.
- To evaluate the feasibility and efficacy of percutaneous bupivacaine instillation for post-operative pain control.
Main Methods:
- A technique involving percutaneous instillation of bupivacaine into the flexor tendon sheath is described.
- A thin catheter with an antibacterial filter is utilized for precise drug delivery.
Main Results:
- The described method facilitates immediate post-operative mobilization without significant pain.
- This approach aims to prevent the formation of adhesions and improve tendon gliding.
Conclusions:
- Percutaneous bupivacaine instillation offers a promising strategy for enhanced recovery after Zone II flexor tendon surgery.
- This technique supports early, pain-free mobilization, potentially improving functional outcomes in hand surgery patients.

Skeletal Muscle Relaxants: Therapeutic Uses
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx as...
Local Anesthetics: Differential Sensitivity of Nerve Fibers
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
Local Anesthetics: Clinical Application as Epidural Anesthesia
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
