Purpose Wide-awake local anesthesia with no tourniquet has dramatically changed hand surgery practice. Using lidocaine with epinephrine and no tourniquet has allowed many procedures to be moved from the main operating room to an in-office procedure room. Previous studies have shown that using local anesthesia is safe and cost effective, with high p...

The presence of tophaceous gout in the hand is a classic finding seen in uncontrolled gout. Occasionally gouty tophi can be the initial physical finding in asymptomatic hyperuricemia. Composed of monosodium urate (MSU) crystals, gouty tophi can cause significant soft tissue and joint pathology. In addition, tophaceous gout and hyperuricemia are ass...
Article
Acute calcific tendinitis (ACT) is a relatively uncommon disorder that can involve the hand and wrist. ACT is frequently misdiagnosed due to a lack of familiarity with the condition and the clinical presentation that can be confused with other conditions. We report a case of acute calcific tendinitis of the flexor carpi ulnaris (FCU) tendon in a 68...
Article
Avulsion of the flexor digitorum profundus (FDP) tendon is a relatively common injury in athletes. Also known as "jersey finger," it can also occur in nonathletes, and is often not initially diagnosed. Early diagnosis and repair are essential to regaining optimum return of function. We report a case of a 37-year-old woman who was seen six weeks fol...
Article
Background: North American surgeons continue to routinely order narcotic medication for postoperative pain relief after carpal tunnel surgery. For some patients, this instigates persistent use. This double-blind, multicenter trial investigated whether over-the-counter medications were inferior to opioid pain control after carpal tunnel release. M...

Information regarding the management of intra-articular base fractures of the index metacarpal is scarce. Fractures of the base of the index metacarpal are rare because of the inherent stability of the joint. Of the handful of case reports on this injury, there appear to be 2 main patterns: fractures of the dorsal radial condyle and fractures of th...
Article
The use of low-dose 1 percent lidocaine with epinephrine (1:100,000) has changed the practice of hand surgery. The safety of lidocaine and epinephrine in hand surgery has been well documented. Although rare, epinephrine-induced digital vasospasm can occur leading to tissue necrosis and amputation. Fortunately, digital ischemia can be reversed with...

Lipoma is the most common type of benign soft tissue tumor and is composed of mature adipose tissue. A neoplasm of adipose tissue with admixed mature bone and cartilage, or osteochondrolipoma, is an extremely rare histologic variant. Most documented osteochondrolipomas have occurred in the soft tissues of the head and neck related to the oral cavit...
Article
Distal radius fractures are one of the most common orthopedic injuries, particularly in the elderly population. Distal radius nonunions are rare and are usually associated with a patient's underlying health conditions. We present a patient who developed a distal radius nonunion following treatment of an open wrist fracture with an external fixation...
Article
Distal radius fractures account for 18 percent of all fractures in the elderly age group. It is estimated that the yearly cost of treatment for distal radius fractures approaches $240 million. The frequency of fractures will continue to increase with the aging population. The operative treatment of distal radius fractures has changed dramatically w...

Animal vaccine injection injuries of the hand are of special concern in veterinary medicine and agricultural fields. Although most of these injuries resolve with no or minimal treatment, major complications can occur. We report a case of a farmworker who experienced an accidental needlestick injury while vaccinating pigs. The operative findings, po...
Article
Osteomyelitis pubis is a rare orthopedic infection, accounting for less than 1-2 percent of all hematogenous osteomyelitis. Osteomyelitis pubis generally affects children, elderly patients who have undergone genitourinary procedures, and parenteral drug users. Interestingly, cases of acute osteomyelitis pubis have also been documented in previously...

A 46-year-old female presented after 3 years of steadily increasing numbness in her hands bilaterally with worse symptoms in her right hand. She reported nighttime paresthesia and exacerbation of her symptoms while writing, typing, and driving. Tinel’s and carpal tunnel compression test were positive bilaterally. During the right hand carpal tunnel...

Health care in the United States is both expensive and wasteful. The cost of health care in the United States continues to increase every year. Health care spending for 2016 is estimated at $3.35 trillion. Per capita spending ($10,345 per person) is more than twice the average of other developed countries. The United States also leads the world in...

With the emphasis on pain control (i.e., pain as the fifth vital sign) starting in the late 1990s and the increased prescribing of opioids, the opioid epidemic began. With the expanding misuse of opioids a new emphasis has been given for more responsible management of opioid prescribing by health care providers in all specialties. Since the pain ex...
Article
Background: Wide-awake local anesthesia and no tourniquet (WALANT) has become more popular in hand surgery. Without a tourniquet, there is no need for preoperative testing or sedation. The use of lidocaine with epinephrine has allowed a larger variety of cases to be done safely in an outpatient setting instead of the hospital. "Minor field sterili...
Article
Background: Flexor tendon ruptures in the wrist are uncommon. Flexor carpi radialis (FCR) tendon rupture can occur in rheumatoid patients, following cortisone injection for tenosynovitis, and following trauma. Following tendon rupture, tethering of the ruptured FCR tendon, or pseudotendon, can form which may or may not be symptomatic. Methods: A li...
Article
Hook of the hamate fractures are uncommon. This fracture is usually seen in sports involving a club or a racquet (i.e., baseball or golf) and is caused by blunt trauma. Stress fractures of the hamate are exceedingly rare. Because of its subcutaneous position and associated soft tissue structures, hook of the hamate fractures can be difficult to dia...
Article
Since the publication of Baron Dupuytren's first paper 180 years ago, the treatment of Dupuytren's disease continues to be problematic. Because of the high recurrence rate following surgery, there has been a shift to more radical surgical options. Unfortunately, this has led to more frequent and sometimes serious postoperative complications. Recent...
Article
Nonunions of fractures occur infrequently and can be multifactorial. Some predisposing factors include fracture instability, poor vascularity and inadequate fracture reduction. The role of metabolic bone disease and endocrine abnormalities in nonunions is often overlooked. This article reports a case of a tibial nonunion associated with vitamin D d...
