BACKGROUND: Postoperative pillar pain (deep-seated wrist pain worsened by leaning on the heel of the hand) sometimes occurs after carpal tunnel release (CTR), leading to weakness in the hand and delayed return to work. Increased pain sensitivity has been found to be associated with worse symptoms and poorer treatment response in a number of chronic musculoskeletal conditions, but few studies have investigated the association of pain sensitization with pillar pain after CTR. QUESTIONS/PURPOSES: (1) Is preoperative pain sensitization in patients with carpal tunnel syndrome (CTS) associated with increased severity of pillar pain after open CTR? (2) What other demographic, electrophysiological, or preoperative clinical characteristics are associated with pillar pain after CTR? METHODS: Over a 35-month period, one surgeon performed 162 open carpal tunnel releases...

Hereditary multiple osteochondroma (HMO) is an autosomal dominant genetic disorder characterized by multiple outgrowing bony tumors capped by cartilage, generally affecting the metaphyses. The disease is known as hereditary multiple exostoses, familial exostosis, multiple cartilaginous exostoses or hereditary malformation of cartilage. The prevalence of HMO in Europe and the Unites States is ~1:100,000, although it has not been reported in China. The disease is often accompanied by pain, asymmetry and skeletal malformations, including forearm and leg bending deformities, limb length discrepancies, and knee internal and external rotation abnormalities...

The Sauvé-Kapandji procedure is a reliable option for patients with various disorders of the distal radioulnar joint (DRUJ). However, postoperative pain over the proximal ulnar stump frequently develops during forearm rotation or when lifting heavy objects, although many clinically satisfactory results have been reported. This stump pain has been suggested to result from dynamic instability of the proximal ulnar stump. Several types of tenodesis have recently been performed simultaneously with the Sauvé-Kapandji procedure to stabilize the proximal ulnar stump and thus relieve the associated pain...

Performance in motorcycle road racing is typically considered as the summation of interactions between rider, motorcycle, tires, and environment. Despite the substantial investments made towards the development of motorcycle technology and the business interests of manufacturers, published research focusing on the riders is relatively sparse, and a bike-centered mentality tends to dominate the sport. This manuscript reviews the known human performance aspects of motorcycle road racing and suggests directions for future research...

BACKGROUND: Due to the rising incidence of penile cancer and increasing life expectancy in western nations, the current international guidelines recommend a less aggressive surgical approach with reduced safety margins and preferably with organ preservation. OBJECTIVES: The goal of this review is to review the current data on stage-dependent reconstructive surgical techniques and their oncological and functional results. MATERIALS AND METHODS: Five recently published reviews and several single studies and publications on the topic of organ-sparing surgical techniques and penile reconstruction were evaluated to draw conclusions for surgery in penile cancer...

BACKGROUND The complication rate of central venous catheterization ranges from 4% to 35%. Brachial plexus injury can occur, mostly on the same side as the catheterization, without affecting the contralateral brachial plexus. CASE REPORT A 71-year-old woman received placement of a vein hemodialysis catheter via right internal jugular vein. Five days after the cannulation, she complained of contralateral burning pain and numbness at the ulnar side of her left forearm. On the next day, the pain increased and extended to her left shoulder girdle and whole left arm, despite use of analgesics...

BACKGROUND: Most brachial plexus birth injuries (BPBI) are caused by traction on the brachial plexus during a difficult delivery. Fortunately, the possibility of complete recovery from such an incident is relatively high, with only 10% to 30% of patients having prolonged and persistent disability. These patients have muscle imbalances and co-contractions typically localized around the shoulder and elbow. These imbalances and co-contractures cause abnormal motor performances and bone/joint deformities...

PURPOSE: Although acute compartment syndrome (ACS) is associated with pediatric supracondylar humerus (SCH) fractures, there are limited data describing its incidence and risk factors. The purpose of our study was to report the local and national incidence of ACS with SCH and floating elbow (concomitant SCH and forearm) fracture patterns and the associated risk factors. METHODS: We retrospectively queried data for SCH fracture patients over a 4-year period from our institution (a level I pediatric trauma center) and the National Trauma Data Bank (NTDB)...

BACKGROUND: Previous studies have showed the efficacy of removable brace treatment for distal radius buckle fractures in children, whereas others have independently suggested that these injuries do not require additional radiographic imaging. However, no study has sought to collectively determine whether treating pediatric distal radius buckle fractures with a removable brace and no follow-up visit or imaging after the initial visit is a safe and satisfactory protocol. METHODS: In total, 42 consecutive patients with a distal forearm buckle fracture seen by a single fellowship trained pediatric orthopaedic surgeon were eligible to participate...

NEW FINDINGS: What is the central question of this study? We examined whether the mechanical contribution to contraction-induced rapid onset vasodilatation (ROV) differed with age, and whether ROV is associated with peripheral artery stiffness. Furthermore, we examined how manipulation of perfusion pressure modulates ROV in young and older adults. What is the main finding and its importance? The mechanical contribution to ROV is similar in young and older adults. Conversely, peripheral arterial stiffness is not associated with ROV...

OBJECTIVE: Arteriovenous (AV) fistulas are the preferred hemodialysis access for patients with end-stage renal disease, although multiple interventions are typically needed to maintain patency. When AV fistulas thrombose, however, there is debate as to whether open thrombectomy should be attempted, particularly for salvage of upper arm fistulas. This study was designed to evaluate outcomes after open thrombectomy of upper arm and forearm AV fistulas compared with AV grafts. METHODS: We identified all patients who underwent an open thrombectomy procedure for a thrombosed AV fistula or graft at a single academic medical center between January 2006 and March 2017...

This review aims to summarize the basic treatment principles of fractures according to their types and general management principles of special conditions including physeal fractures, multiple fractures, open fractures, and pathologic fractures in children. Definition of the fracture is needed for better understanding the injury mechanism, planning a proper treatment strategy, and estimating the prognosis. As the healing process is less complicated, remodeling capacity is higher and non-union is rare, the fractures in children are commonly treated by non-surgical methods...
