RESUMEN
Brachial plexus block provides effective anesthesia and analgesia for upper extremity surgery but requires injection of large anesthetic volumes near major vascular structures. Moreover, the extensive motor and sensory loss produced by plexus block often exceeds the neural distribution needed for corresponding surgical procedures.High-resolution ultrasound facilitates selective nerve blocks at nearly every level of the upper extremity. We present fascial plane injection techniques for selective radial, median, and ulnar nerve blocks. These techniques can be used to match sensory distribution with specific surgical procedures. They are performed using low anesthetic volumes and without proximity to nerves or vascular structures. In this article, fresh cadaver dissections with corresponding ultrasound images are used to demonstrate stepwise fascial plane techniques for the radial, median, and ulnar nerves. These techniques are performed using familiar anatomic landmarks.Practical applications of these techniques are demonstrated for commonly performed procedures of the upper extremity. Corresponding injection volumes with duration of postoperative analgesia are presented. Selected injections are described for both surgical anesthesia and postoperative analgesia.Selective fascial plane injections can provide surgical anesthesia and postoperative analgesia in settings that might otherwise require much larger volumes of local anesthetic. These selective nerve blocks can match sensory loss with the anatomic pain distribution in each patient. Reliable techniques for selective nerve blocks of the upper extremity can expand the capabilities for ultrasound-guided regional anesthesia.

Background. First metatarsophalangeal (MTP) arthrodesis is the "gold standard" treatment for hallux rigidus. Recently, there has been increased interest in new synthetic cartilage implants to preserve joint motion while eradicating pain. With current health care economics, the cost of a treatment is gaining particular importance. This study set out to perform a cost comparison between MTP arthrodesis and synthetic hydrogel implant to determine which treatment modality is more cost-effective based on direct aggregate costs. Study design. Economic and decision analysis. Methods. Studies in the available literature were analyzed to estimate hardware removal rates for MTP fusion and failure rates for a synthetic hydrogel implant and MTP fusion. Costs were determined by examining direct costs at a single institution for implants and data reported in the literature for operating room time. Sensitivity analysis and Monte Carlo simulation were performed to examine cost and measurement uncertainty. Results. Assuming a 4.76% MTP arthrodesis revision rate and 7.06% hardware removal rate, the total direct cost of MTP joint arthrodesis was $3632. Using a 9.2% failure rate with subsequent conversion to MTP arthrodesis, the total cost of synthetic hydrogel implant was $4565. Sensitivity analysis revealed that MTP fusion was more cost-effective even if the failure rate increased to 15% and synthetic hydrogel implant failure rate was 0%. The synthetic cartilage implant cost would have to be reduced 28% or approximately 200% the cost of MTP fusion implants to be comparable to MTP arthrodesis. Conclusion. Hallux rigidus treatment with a synthetic hydrogel implant resulted in a higher direct aggregate cost than MTP arthrodesis.Level of Evidence: Level II: Cost analysis.

We evaluated the feasibility of a mentored gardening intervention for adolescent and young adult (AYA) cancer survivors in a hospital-based community garden as a way to improve diet and physical activity, using qualitative data to assess the challenges, facilitators, and areas for future programmatic improvement and replication. Over the course of growing season 2018, AYA cancer survivors tended a garden plot in a community garden under the mentorship of an experienced (master) gardener. AYA cancer survivors were successful in planting and harvesting vegetables from the garden in partnership with their mentors. Qualitative results and future directions for the project are discussed.
