As reimbursements decline and overhead costs continue to rise, physicians, especially those in private practice, are finding it more difficult to maintain an operating margin that allows them to continue to deliver quality care to patients while maintaining their desired standard of living. Many models solve this by increasing patient volume, which either means increased hours spent in office or less time spent with patients. Unfortunately, it often means both. New policies, in particular those introduced by the Centers for Medicare and Medicaid Services (CMS), often add to the burden of practice by requiring additional information gathering, strict adherence to new coding systems and meticulous documentation. These new requirements may stress the system by overwhelming patients with paperwork, slowing patient flow and sometimes leading to denied payment. If we are to continue to deliver quality care to our patients while ensuring value and satisfaction, we must find ways to eliminate waste and minimize redundancy. In short, we must learn to do more with less.

Healthcare is changing from volume based fee for service to value based care with alternative payment models including bundled payments. Healthcare systems, physicians, and patients are being held accountable for escalating and non-sustainable healthcare costs. Deductibles and co-pays continue to increase while reimbursement is decreasing requiring stakeholders to engage in fiscally responsible decision making regarding the cost of delivering care. An increasingly popular approach to cost containment and value based care is a value analysis program which requires the engagement and collaboration of physicians, group practices, healthcare systems, hospitals, and vendors. A successful value analysis program should be standardized, transparent, and without conflict of interest. Physician expectations regarding the process have been identified and should be incorporated into the process.

Upper extremity lymphedema is a dreaded and not uncommon complication from the treatment of breast cancer. Professional hand surgeons with microsurgical skills must be one of the major groups of future lymph surgeons for upper extremity lymphedema. Anatomical and theoretical advances in treating upper extremity lymphedema make it possible to cure upper extremity lymphedema by surgical approaches. In this course, participants understand current surgical approaches for upper extremity lymphedema. After the course, participants have motivations to be future leaders of lymph surgeons with their new insights.

Objectives: Following this session, the participant will be able to:

1. Discuss how to detect lymphatic vessels in upper extremity.
2. Identify how to perform lymphaticovenular anastomosis for upper extremity lymphedema.
3. Discuss how to perform local and free lymph node transfer for upper extremity lymphedema

An injury to the upper motor neuron results in impaired regulation of motor activity that can manifest as hyper-reflexia or spasticity. This can lead to an imbalance of forces across the joint and result in static or dynamic deformities in the upper extremities. In severe cases, these deformities can result in hygiene issues and markedly decrease quality of life. The goals of surgical reconstruction are to reduce pain, improve hygiene, enhance functionality, and to correct unaesthetic contractures. This course will review the evaluation and management of this unique and underserved patient population. A case-based format will be utilized to illustrate the approach to managing common spastic deformities in the upper extremity based on the functionality of the extremity. Participants will be able to incorporate the techniques discussed into their practice towards the treatment of mild to severe spastic deformities in the upper extremities.

Objectives: Following this session, the participant will be able to:

1. Explain the impact of upper extremity spasticity on function and quality of life
2. Describe the indications and goals for upper extremity surgery in patients with upper motor neuron syndrome.
3. Recognize the surgical approach to decrease spasticity in the functional and non-functional upper extremity.

Join us for this case based discussion where the faculty will share on decision making pearls and technical tips and tricks in the management of scaphoid fractures and nonunions.

Objectives: Following this session, the participant will be able to:

1. Describe the general approach in managing scaphoid fractures.
2. Discuss arthroscopic treatment for scaphoid fractures
3. Recognize arthroscopic management for scaphoid fracture sequalae

The faculty will teach the audience different surgical techniques employed when performing a thumb reconstruction with either a toe transplantation or a toe wrap, providing them a better idea of the intraoperative steps, as well as tips and tricks to optimize surgical outcomes.

Objectives: Following this session, the participant will be able to:

1. Discuss the principles of thumb reconstruction using microsurgery Learn the steps employed in a toe to thumb transplantation
2. Discuss the steps involved in a toe wrap thumb reconstruction
3. Discuss the additional procedures necessary to improve function after the above mentioned procedures

This course will discuss the mechanism of injury and clinical presentation of common hand and wrist injuries in the pediatric patient population. It will include recommendations for early diagnosis and stabilization of these conditions, timing for appropriate treatment in this patient group, and surgical and non-operative management of these injuries. Post-injury and post-operative hand therapy techniques utilized in the pediatric patient population will also be reviewed.

Objectives: Following this session, the participant will be able to:

1. Identify common pediatric hand and wrist injuries.
2. Learn how to triage and appropriately stabilize these conditions in the acute injury period.
3. Develop operative and non-operative treatment plans for common pediatric hand and wrist injuries, including incorporation of occupational therapy techniques to improve functional outcomes

Compression neuropathy can lead to pain and extremity dysfunction. This course will address aspects of nerve compression syndromes that are challenging with regards to diagnosis and treatment. This group of experts will highlight innovations and opportunities to improve outcomes including diagnostic pearls, supercharge nerve transfers and electrical stimulation.

Objectives: Following this session, the participant will be able to:

1. Summarize challenges of nerve compression syndromes, including recurrent conditions.
2. Develop a treatment algorithm for patients with compression neuropathies.
3. Learn perioperative strategies, i.e. diagnostic pearls, supercharge nerve transfers, electrical stimulation, to enhance recovery in patients with nerve compression syndromes

High nerve injuries pose a difficult reconstructive challenge. The use of nerve transfers to restore function have become more popular in upper extremity nerve reconstruction; however, the reliability of tendon transfers is still profound. The experts in this course will debate the indications, use and feasibility of these two reconstructive options to maximize outcomes.

Objectives: Following this session, the participant will be able to:

1. Discuss the indications, risks and benefits of using tendon transfers versus nerve transfers to restoring function after high nerve injury.
2. Develop a treatment algorithm for high nerve injuries.
3. Learn innovative techniques to restore high nerve injuries.

In this lecture, Dr. James Chang will discuss an exhibit at the Cantor Arts Center based on Auguste Rodin's sculptures. This multi-media art exhibit was a unique collaboration between Stanford Hand Surgery, Anatomy, and Art History.
While training in surgery, Dr. Chang saw correlations between the Rodin hand sculptures and actual hand and microsurgery patients he was treating. This concept became the basis for a Stanford undergraduate course where students dissect human limbs and learn reconstructive techniques in order to diagnose and treat Rodin's hands. The Rodin hands have now been scanned, and computer graphics have been used to allow a look inside Rodin's hands. Dr. Chang's lecture will discuss how he uses Rodin's hands for teaching anatomy and surgery. He will make clinical correlations to a specific hand conditions and hand operations.

Objectives: Following this session, the participant will be able to:

1. Discuss the historical significance of Auguste Rodin's hand sculptures.
2. Identify clinical correlations between Rodin's hands and common hand disorders.
3. Discuss optimal techniques in hand and microvascular surgery

The management of brachial plexus injuries has continued to evolve over the last few decades. This panel of nerve experts will provide a comprehensive update on the management of patients (pediatric and adult) with brachial plexus injuries. This will include the use of nerve transfers in adults and birth related plexus injuries, contralateral C7 transfers, timing of intervention and advances in neuroimaging.

Injuries to the extensor tendons of the hand are common. Each zone of injury has specific therapeutic requirements due the unique anatomy. This course will review the current literature on therapeutic management of the extensor tendons at Zones I-VI. Demonstrations of specific orthoses and therapeutic exercises will be included.

1. Identify the specific digit extensor tendon anatomy at zones I-VI.
2. Select the appropriate orthosis for therapeutic postoperative management of extensor tendon injuries depending on the zone of injury.
3. Describe how the yoke or relative motion orthosis can be used for management of specific extensor tendon injuries.

Experienced faculty will deliver a review of commonly encountered hand and upper extremity conditions using a combination of case based presentations and lectures. They will cover principles of diagnosis and treatment, while providing an overview of conditions encountered on board examinations and resident in-training examinations. The course is ideal for residents, fellows and hand therapists who wish to increase depth of knowledge in hand surgery as well as surgeons in practice seeking a knowledge update or preparing for a MOC exam.

Objectives: Following this session, the participant will be able to:

1. Discuss non-operative and operative treatment approaches for various commonly encountered disorders of the hand and wrist.
2. Identify treatment options available for disorders of the hand and upper extremity.
3. Recognize various uncommon and/or unusual clinical conditions of the hand and wrist including carpal and DRUJ conditions, peripheral nerve, tendon and other common problems.
4. Compare different treatment methods to avoid complications and improve patient outcomes.

Registration for this course is limited to young surgeons that have/will complete their hand surgery fellowship in years 2018, 2019, 2020 and 2021 and are interested in preparing hand surgery cases for their upcoming oral boards examination. Registrants are asked to submit a case in which they have participated as surgeon or assistant. The case submission should include a 1-2 paragraph vignette with x-ray images if needed. The course directors will select the most instructive cases for the course oral boards-style presentation. If selected, the registrant will present the case for oral board examination presentation, questions by the experienced faculty “Board examiners” and questions from the audience. The faculty “board examiners will provide an evidence-based review of each controversial topic for rapid digestion of important Board examination points. In order to best prepare for the oral boards, all attendees, whether presenting or observing, will be able to participate in this small group format.

Objectives: Following this session, the participant will be able to:

1. Discuss non-operative and operative treatment for various commonly encountered disorders of the hand and wrist.
2. Identify topics and controversies that could be discussed in oral board examinations.
3. Better prepare their case presentations and examination responses for the oral boards.
4. Discuss evidence-based management of hand surgery cases discussed.

Recent advances in technology and surgical techniques is revolutionizing the world of prosthetics. This panel of experts will discuss the science behind the technology and describe avenues to improving function and minimizing complications in patients with limb amputations.

End to side nerve transfers, both traditional and supercharge, are gaining popularity among nerve surgeons. This panel will discuss the scientific basis for this nerve transfer technique and how best to apply to patients with nerve injuries. From facial palsy to ulnar neuropathy, the panelists will use a case-based format to highlight opportunities of use.

Objectives: Following this session, the participant will be able to:

1. Discuss the scientific basis for the end to side and reverse end to side coaptations.
2. Learn surgical techniquest to maximize effectiveness with these nerve transfers.
3. Develop an algorithm for the use of end to side nerve transfers to restore function.

We will present the most current approaches to improving prosthetic rehabilitation following limb loss including RPNI and TMR. These discussion will address the indications, surgical approaches, and outcomes following these surgical procedures. In addition, we will discuss the optimal approaches to treat phantom pain, neuroma pain, and CRPS following devastating injuries of the extremities. The goal of the course will be to shed light on all of the approaches available to enhance functional restoration following limb loss.

Objectives: Following this session, the participant will be able to:

1. Discuss how RPNIs and TMR can be used to prevent and treat painful neuromas and phantom pain.
2. Identify how RPNIs and TMR can be used for prosthetic control.
3. Develop the optimal ways to diagnose a neuroma and how to differentiate it form other pain conditions like CRPS.

Duchenne muscular dystrophy (DMD) is a severe, progressive muscle disease caused by mutations in the Dystrophin gene, which encodes a large intracellular protein that maintains integrity of muscle cell membranes. More than 4,000 DMD mutations have been identified in humans. The majority of mutations are deletions that cluster in hot spots, such that skipping of out-of-frame exons can potentially restore the reading frame of the Dystrophin protein. We have used CRISPR/Cas9 to generate new mouse models of DMD lacking the most prominently deleted Dystrophin exons in humans. To permanently correct DMD by skipping mutant dystrophin exons in postnatal muscle tissue in vivo, we have used adeno-associated virus-9 (AAV9) to deliver CRISPR/Cas9 gene editing components to dystrophic mice, a method we refer to as Myoediting. We have also optimized Myoediting of many types of DMD mutations in muscle cells derived from iPS cells generated from blood samples of DMD patients. In a path toward clinical translation of gene editing for DMD, we have recently restored dystrophin expression of dogs with DMD following systemic administration of gene editing components with AAV9. Opportunities and challenges in the path toward permanent correction of disease-causing mutations responsible for DMD and other monogenic disorders by genomic editing will be discussed.

Objectives: Following this session, the participant will be able to:

1. Discuss principles of gene editing.
2. Identify the application of this technology to the correction of DMD.
