The Influence of Mental Health Diagnoses on Patient Experiences and Outcomes in Patients Undergoing WALANT Hand Surgery.

Purpose: The purpose of this study was to gauge whether patients with preexisting mental health conditions have desirable outcomes when undergoing wide-awake local anesthesia with no tourniquet (WALANT) hand surgery. Methods: A retrospective review of 133 patients who underwent WALANT surgery by 2 senior authors from August 2019 to October 2020 was performed. Patients were administered a 10-question postoperative survey detailing perioperative pain, experience, and satisfaction concerning their procedure. Analysis was performed for patient responses to the questionnaire, demographics, comorbidities, and patient-reported outcomes using the Single Assessment Numeric Evaluation (SANE). Results: There were 61 patients identified as having a preexisting psychiatric diagnosis compared to 70 patients without who underwent WALANT surgery. Comparing psychiatric diagnosis and nonpsychiatric diagnosis cohorts, there was no significant difference in preoperative anxiety (3.75 vs 3.30), pain during procedure (0.67 vs 0.56), or pain after surgery (4.89 vs 4.26). There was a significantly higher pain score with preoperative injection in the psychiatric diagnosis cohort (4.07 vs 2.93). When asked if they would have a WALANT procedure again, 95.1% of patients in the psychiatric diagnosis cohort and 98.6% of patients in the nonpsychiatric diagnosis group said they would. There was no significant difference in average preoperative SANE scores (59.67 [no psych diagnosis] vs 61.70 [psych diagnosis]) or postoperative SANE scores (82.82 [no psych diagnosis] vs 81.06 [psych diagnosis]) between the two cohorts. Conclusions: WALANT surgery was nearly as well tolerated in patients with a preexisting mental health diagnosis when compared to those without a preexisting diagnosis. Clinical Relevance: Surgeons who are currently or potentially performing WALANT surgery should not rule out patients as eligible candidates because of a prior diagnosis of a mental health condition.

WALANT Technique versus Sedation for Endoscopic Carpal Tunnel Release.

BACKGROUND: This study sought to investigate complication rates/perioperative metrics after endoscopic carpal tunnel release (eCTR) via wide-awake, local anesthesia, no tourniquet (WALANT) versus sedation or local anesthesia with a tourniquet. METHODS: Patients aged 18 years or older who underwent an eCTR between April 28, 2018, and December 31, 2019, by 1 of 2 fellowship-trained surgeons at our single institution were retrospectively reviewed. Patients were divided into 3 groups: monitored anesthesia care with tourniquet (MT), local anesthesia with tourniquet (LT), and WALANT. RESULTS: Inclusion criteria were met by 156 cases; 53 (34%) were performed under MT, 25 (16%) under LT, and 78 (50%) under WALANT. The MT group (46.1 ± 9.7) was statistically younger compared with LT (56.3 ± 14.1, P = .007) and WALANT groups (53.5 ± 15.8, P = .008), F(2, 153) = 6.465, P = .002. Wide-awake, local anesthesia, no tourniquet had decreased procedural times (10 minutes, SD: 2) compared with MT (11 minutes, SD: 2) and LT (11 minutes, SD: 2), F(2, 153) = 5.732, P = .004). Trends favored WALANT over MT and LT for average operating room time (20 minutes, SD: 3 vs 32 minutes, SD: 6 vs 23 minutes, SD: 3, respectively, F(2, 153) = 101.1, P < .001), postanesthesia care unit time (12 minutes, SD: 7 vs 1:12 minutes, SD: 26 vs 20 minutes, SD: 22, respectively, F(2, 153) =171.1, P < .001), and door-to-door time (1:37 minutes, SD: 21 vs 2:51 minutes, SD: 40 vs 1:46 minutes, SD: 33, respectively, F(2, 153) = 109.3, P < .001). There were no differences in complication rates. CONCLUSIONS: Our data suggest favorable trends for patients undergoing eCTR via WALANT versus MT versus LT.

Wide Awake Local Anesthesia No Tourniquet Technique in Hand Surgery: The Patient Experience.

BACKGROUND: We attempted to evaluate patient satisfaction and overall experience during wide awake, local anesthesia, with no tourniquet (WALANT) hand surgery and quantify surgery-related outcomes. METHODS: We conducted a retrospective analysis of patient demographics, comorbidities, and patient reported outcomes via Single Assessment Numeric Evaluation (SANE) scores collected pre- and postoperatively of patients undergoing WALANT surgery by the 2 participating senior authors. A solution of 1% lidocaine with 1:100,000 epinephrine was used by 1 surgeon, while the other used a 1:1 ratio of 1% lidocaine with 1:100,000 epinephrine and 0.5% bupivacaine for local anesthetic injection. Patients were administered a postoperative survey to assess patient experience, including anxiety and pain levels, and overall satisfaction in the perioperative period. RESULTS: Overall, 97.7% of patients indicated that they would undergo a WALANT-style surgery if indicated in the future, 70.5% ate the day of surgery, and a total of 39.1% of patients reported driving to and from surgery. Postoperative SANE scores increased as compared with preoperative scores across all patients. The use of combination 1% lidocaine with 1:100,000 epinephrine and 0.5% bupivacaine was associated with lower intraoperative and postoperative visual analog scale pain scores. CONCLUSIONS: WALANT hand surgery was generally well tolerated with excellent surgical outcomes. Patients reported ease of preparation for surgery, faster recovery, and lack of anesthetic side effects as the main benefits of wide-awake surgery. Combination use of lidocaine and bupivacaine may be better than lidocaine alone with respect to pain control in the initial recovery period.

Suture Tape Augmentation for the Repair of Index Finger Radial Collateral Ligament Injury: A Biomechanical Study.

PURPOSE: Despite their clinical importance in maintaining the stability of the pinch mechanism, injuries of the radial collateral ligament (RCL) of the index finger may be underrecognized and underreported. The purpose of this biomechanical study was to compare the repair of index finger RCL tears with either a standard suture anchor or suture tape augmentation. METHODS: The index fingers from 24 fresh-frozen human cadavers underwent repair of torn RCLs using either a standard suture anchor or suture tape augmentation. Following the repairs, the initial displacement of the repair with a 3-N ulnar deviating load was evaluated. Next, the change in displacement (cyclic deformation) of the repair after 1,000 cycles of 3 N of ulnar deviating force was calculated (displacement of the 1000th cycle - displacement of the first cycle). Finally, the amount of force required to cause clinical failure (30° ulnar deviation) of the repair was determined. RESULTS: Suture tape augmentation repairs displayed significantly less cyclic deformation (0.8 ± 0.5 mm) after cyclic loading than suture anchor repairs (1.8 ± 0.7 mm). There was no significant difference in the force required to cause the clinical failure of the repairs between the suture tape (35.1 ± 18.1 N) and suture anchor (24.5 ± 9.2 N) repairs. CONCLUSIONS: Index finger RCL repair with suture tape augmentation results in decreased deformation with repetitive motion compared with RCL repair alone. CLINICAL RELEVANCE: Suture tape augmentation may allow for early mobilization following index finger RCL repair by acting as a brace that protects the repaired ligament from deforming forces.

Valve or No Valve: A Prospective Randomized Controlled Trial of Casting Options for Pediatric Forearm Fractures.

The purpose of this study was to determine the rate of cast-related complications when using split or intact casts. A total of 60 patients aged 3 to 13 years with closed shaft or distal third radius and ulna fractures requiring reduction were recruited for this study. Patients underwent closed reduction under sedation and were placed into a long-arm fiberglass cast with 1 of 3 modifications: no valve, univalve, or bivalve. Patients were followed to 6 weeks after reduction or surgical treatment if required. The frequency of neurovascular injury, cast saw injury, unplanned office visits, and cast modifications, the need for operative intervention, and pain levels through the follow-up period were recorded. The results showed no incidents of compartment syndrome or neurovascular injury. Additionally, there were no differences between complications associated with cast type (P=.266), frequency of cast modifications (P=.185), or subsequent need for surgical stabilization (P=.361). Therefore, cast splitting following closed reduction of low-energy pediatric forearm fractures does not change clinical outcomes with respect to neurovascular complications, cast modifications, pain levels, or the need for repeat reduction. Consideration should be given to minimizing cast splitting after reduction of low-energy pediatric forearm fractures for practice efficiency and to potentially decrease saw-related injury.

The effect of a combined glenoid and Hill-Sachs defect on glenohumeral stability: a biomechanical cadaveric study using 3-dimensional modeling of 142 patients.

BACKGROUND: Bone loss in anterior glenohumeral instability occurs on both the glenoid and the humerus; however, existing biomechanical studies have evaluated glenoid and humeral head defects in isolation. Thus, little is known about the combined effect of these bony lesions in a clinically relevant model on glenohumeral stability. HYPOTHESIS/PURPOSE: The purpose of this study was to determine the biomechanical efficacy of a Bankart repair in the setting of bipolar (glenoid and humeral head) bone defects determined via computer-generated 3-dimensional (3D) modeling of 142 patients with recurrent anterior shoulder instability. The null hypothesis was that adding a bipolar bone defect will have no effect on glenohumeral stability after soft tissue Bankart repair. STUDY DESIGN: Controlled laboratory study. METHODS: A total of 142 consecutive patients with recurrent anterior instability were analyzed with 3D computed tomography scans. Two Hill-Sachs lesions were selected on the basis of volumetric size representing the 25th percentile (0.87 cm(3); small) and 50th percentile (1.47 cm(3); medium) and printed in plastic resin with a 3D printer. A total of 21 cadaveric shoulders were evaluated on a custom shoulder-testing device permitting 6 degrees of freedom, and the force required to translate the humeral head anteriorly 10 mm at a rate of 2.0 mm/s with a compressive load of 50 N was determined at 60° of glenohumeral abduction and 60° of external rotation. All Bankart lesions were made sharply from the 2- to 6-o'clock positions for a right shoulder. Subsequent Bankart repair with transosseous tunnels using high-strength suture was performed. Hill-Sachs lesions were made in the cadaver utilizing a plastic mold from the exact replica off the 3D printer. Testing was conducted in the following sequence for each specimen: (1) intact, (2) posterior capsulotomy, (3) Bankart lesion, (4) Bankart repair, (5) Bankart lesion with 2-mm glenoid defect, (6) Bankart repair, (7) Bankart lesion with 2-mm glenoid defect and Hill-Sachs lesion, (8) Bankart repair, (9) Bankart lesion with 4-mm glenoid defect and Hill-Sachs lesion, (10) Bankart repair, (11) Bankart lesion with 6-mm glenoid defect and Hill-Sachs lesion, and (12) Bankart repair. All sequences were used first for a medium Hill-Sachs lesion (10 specimens) and then repeated for a small Hill-Sachs lesion (11 specimens). Three trials were performed in each condition, and the mean value was used for data analysis. RESULTS: A statistically significant and progressive reduction in load to translation was observed after a Bankart lesion was created and with the addition of progressive glenoid defects for each humeral head defect. For medium (50th percentile) Hill-Sachs lesions, there was a 22%, 43%, and 58% reduction in stability with a 2-, 4-, and 6-mm glenoid defect, respectively. For small (25th percentile) Hill-Sachs lesions, there was an 18%, 27%, and 42% reduction in stability with a 2-, 4-, and 6-mm glenoid defect, respectively. With a ≥2-mm glenoid defect, the medium Hill-Sachs group demonstrated significant reduction in translation force after Bankart repair (P < .01), and for the small Hill-Sachs group, a ≥4-mm glenoid defect was required to produce a statistical decrease (P < .01) in reduction force after repair. CONCLUSION: Combined glenoid and humeral head defects have an additive and negative effect on glenohumeral stability. As little as a 2-mm glenoid defect with a medium-sized Hill-Sachs lesion demonstrated a compromise in soft tissue Bankart repair, while small-sized Hill-Sachs lesions showed compromise of soft tissue repair with ≥4-mm glenoid bone loss. CLINICAL RELEVANCE: Bipolar bony lesions of the glenoid and humeral head occur frequently together in clinical practice. Surgeons should be aware that the combined defects and glenoid bone loss of 2 to 4 mm or approximately 8% to 15% of the glenoid could compromise Bankart repair and thus may require surgical strategies in addition to traditional Bankart repair alone to optimize stability.
