Comparative Evaluation of Two Different Post-Operative Analgesia After Hallux Valgus Correction
Study Details
Study Description
Brief Summary
Background: Recent studies showed the efficiency of several techniques of anesthesia in foot surgery. The new mini-invasive surgical approaches should require less analgesia and rapid motor recovery after surgery. The aim of this study was the evaluation of two different techniques on postoperative analgesia and motor recovery after hallux valgus correction in one-day surgery patients.

Detailed Description
The hallux valgus surgery is often characterized by a significant post-operative pain difficult to control with oral analgesics. Consequently, large doses of parenteral opioids are often required Various nerve blocks (popliteal, saphenous, sciatic) can give excellent post-operative pain control. Among loco-regional anesthesia techniques, the sciatic nerve block provides good post-operative pain relief after foot surgery. Thus, sciatic nerve block with long-acting local anesthetics (with or without a peri-neural catheter) has been recommended as a primary option. This analgesic approach should cause a difficult discharge in ambulatory and one-day surgery patients, due to the prolonged motor recovery and loss of proprioception and protective pain reflexes. Therefore, it would be preferable to use the sciatic nerve block just for intra- operative anesthesia without affecting motor recovery, and to apply multimodal analgesia for post- operative pain management. Hallux valgus repair can now be done percutaneously, a minimally invasive technique called ''mini-invasive hallux valgus repair'', consisting in osteotomies through 3 to 5 mm incisions, without internal fixation. This approach requires less dissection and exposure, determining a smaller inflammatory response and theoretically causing less pain. Ideal anesthesia for these procedures should provide rapid patient recovery, minimal nursing care requirements in the post- anesthesia care unit and an earlier hospital discharge. It must provide effective analgesia, since the foot surgery is known to induce a moderate-to- severe post-operative pain, that represents one of the major limitations to hospital discharge on the day of surgery and is the main cause of re-admission.
The aim of this matched-control study was to evaluate two different techniques of post-operative analgesia after hallux valgus correction in one-day surgery patients.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Study Group In the study Group the investigators enrolled 26 patients scheduled for hallux valgus surgery and treated with a new analgesici approach. After sub-gluteal sciatic nerve block with short acting local anesthetic (mepivacaine 2%, 15 ml), each patient received an ultrasound-guided Posterior Tibial Nerve Block (PTNB) with levobupivacaine 0,5% (7-8 ml). The investigators measured: the intensity of pain at the baseline (before the surgery) and at 3, 6, 12 and 24 hours (h) using a Visual Analogue Scale (VAS); the consumption of oxycodone in the first 24 hours after surgical treatment and the motor recovery using modified Bromage score. |
|
| Control group The investigators compared the study group with a control group of 26 patients previously scheduled for the same surgery and treated with another post-operative analgesia technique more frequently used in our hospital: local infiltration (Local Infiltration Anesthesia, LIA) with levobupivacaine 0, 5% (15 ml) performed by the surgeon directly on the operative site. |
