Economic and Environmental Impacts of the Wide-Awake, Local Anesthesia, No Tourniquet (WALANT) Technique in Hand Surgery: A Review of the Literature.

The United States spends more on health care than any other country in the world based on the percentage of gross domestic product. This fact is coupled with health care facilities contributing nearly one-tenth of all greenhouse gas emissions in the United States, and with the health care industry's waste contributions to landfills being second only to those of the food industry. In some instances, operating rooms produce the majority of total landfill waste from hospitals; therefore, patients undergoing surgical procedures can have both financial and environmental impacts. Recently, the wide-awake, local anesthesia, no tourniquet technique in hand surgery has grown in popularity. This technique has reportedly allowed surgeons to decrease operating room costs, time, and waste, but without compromising patient safety or outcomes. This comprehensive literature review summarizes the current literature related to the economic and environmental impacts of the wide-awake, local anesthesia, no tourniquet technique in hand surgery.

Baseball Injuries of the Hand and Wrist.

Injuries of the hand and wrist are common in baseball. Because of the unique motions and loads encountered in this sport, physicians treating baseball players may encounter hand and wrist injuries ranging from common to rare. An understanding of these baseball-related injuries must include their pathoanatomy, diagnosis, and treatment options. This knowledge is critical for the general orthopaedic surgeon treating baseball players to allow for timely and appropriate treatment. This article reviews the pathophysiology, diagnosis, and treatment of baseball-related hand and wrist injuries, with a target audience of general orthopeadic surgeons.

Carpal Tunnel Syndrome Surgery: What You Should Know.

Carpal tunnel release (CTR) surgery continues to evolve. Carpal tunnel syndrome remains a primarily clinical diagnosis, although ultrasound has supplemented electrodiagnostic testing as a confirmatory tool. Magnetic resonance imaging of the carpal tunnel has also showed some promise as an alternative method for the examination of the median nerve. Open CTR surgery remains the traditional, and most popular, method of CTR. Wide-Awake, with Local Anesthesia only, and No Tourniquet CTR has emerged as a means to decrease cost and improve pain control and convenience for patients. Endoscopic CTR is increasing in popularity due to its more rapid recovery. The safety profile of endoscopic CTR has improved, and recent studies show similar rates of major complications between open and endoscopic techniques. Nonsurgeon operated ultrasound-guided techniques for release of the transverse carpal ligament have emerged. While promising in early studies, the current evidence in their favor is limited in terms of patient numbers and direct comparison with other techniques. The outcomes of CTR continue to be excellent. Recent research has demonstrated that nerve conduction continues to recover postoperatively over a longer period of time than previously believed. Patient psychological factors play a significant role in outcomes after surgery but do not appear to limit the improvement provided by intervention.

Endoscopic Carpal Tunnel Release with and without Sedation.

BACKGROUND: This study evaluated outcomes and complications with endoscopic carpal tunnel release performed with local anesthesia only versus local anesthesia with sedation. The authors hypothesized that patient outcomes and satisfaction would be equivalent in both groups irrespective of anesthesia type. METHODS: One hundred fifty-four consecutive patients undergoing endoscopic carpal tunnel release with local anesthesia either with or without sedation were prospectively enrolled in a study of satisfaction and outcomes. Patients were surveyed preoperatively and at 2 weeks and 3 months postoperatively to evaluate satisfaction, symptoms, complications, and disability using the 11-question Disabilities of the Arm, Shoulder, and Hand questionnaire survey; the Levine-Katz carpal tunnel survey; and a customized Likert scale. RESULTS: The hypothesis was upheld. Patients reported high levels of satisfaction (96 percent in the local anesthesia group and 93 percent in the local anesthesia with sedation group at 3 weeks). Disability, pain, and symptom scores did not differ significantly between groups at either postoperative time point. After surgery, patients in the sedation group recalled more mean preoperative anxiety (four of 10 versus 2.03 of 10 at 3 months). If they were to undergo surgery again, patients in the sedation group were likely to desire either sedation (68 percent) or general anesthesia (29 percent), whereas patients in the local anesthesia-only group were likely to wish for similar local-only anesthesia (78 percent). There were no reoperations or epinephrine-related complications in either group. CONCLUSIONS: Patients undergoing endoscopic carpal tunnel release with the local anesthesia or local anesthesia plus sedation experience similar levels of satisfaction and outcomes. Both methods of anesthesia provide excellent results and allow surgeons and patients to choose freely between the two anesthetic techniques.

Patient-Reported Disability Measures Do Not Correlate with Electrodiagnostic Severity in Carpal Tunnel Syndrome.

BACKGROUND: Electrophysiologic studies including electromyography and nerve conduction studies play a role in the evaluation of carpal tunnel syndrome (CTS), despite evidence that these studies do not correlate with CTS-specific symptom scores. There is a lack of evidence comparing electrophysiologic data with general measures of function. METHODS: Fifty patients presenting for CTS treatment over an 8-month period were analyzed retrospectively. All patients completed surveys including the Quick Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH) and the Medical Outcomes Study 12-Item Short-Form Survey [(physical component summary 12, mental component summary (MCS-12)]. Electromyography and nerve conduction studies were performed on all patients and compared with outcome scores. RESULTS: Analysis demonstrated no relationship between DASH or MCS-12 and electrodiagnostic severity. No significant correlations were noted between DASH or MCS-12 and median motor or sensory latency. There was a moderate-weak correlation (rho = 0.34) between more severe electrophysiologic grade and better function based on physical component summary 12. CONCLUSIONS: Electrodiagnostic severity grades do not correlate with patient-reported disability, including the DASH and MCS-12 surveys. There is a counterintuitive correlation between more-severe electrodiagnostic findings and decreased physical disability. These findings indicate that disability may not correlate with electrodiagnostic severity of median neuropathy in CTS.
