BACKGROUND: Carpal tunnel syndrome (CTS) can be treated with open carpal tunnel release (OCTR) or endoscopic carpal tunnel release (ECTR). Our goal was to evaluate the safety and efficacy of ECTR versus OCTR in patients with severe CTS. We hypothesized that ECTR would be as safe and effective as OCTR in these patients. METHODS: This was a retrospective cohort study of patients with severe CTS who underwent ECTR or OCTR by E. G. Deune between 2001 and 2014. Variables were patient age, sex, relevant medical history, alcohol and tobacco use, and preoperative electromyography and physical examination results...

BACKGROUND: We hypothesize that depressive and anxiety disorders, chronic pain conditions, and work-related factors are significant determinants of the time interval for return to work (RTW) in the workers' compensation (WC) population following carpal tunnel release (CTR) surgery. METHODS: We retrospectively reviewed records of all WC patients who underwent open CTR surgery over a 5-year period by 1 of 3 fellowship-trained hand surgeons. One hundred fifty-two wrists in 108 patients (64 unilateral, 44 bilateral) met the inclusion criteria...

In the distal radius fracture requires radiographic views that allow you to see the articular surface without interposition. The objective was to determine whether lateral radiographic projections 7 and 22° improve the analysis of this surface. METHOD: Case series study with radiographs of healthy and operated patients, in order to identify the lunate and scaphoid facets in lateral and anteroposterior projections. Qualitative analysis was made on the radiographs of the distal radius with wedges of 7 and 22° in the lateral views and 11° in the anteroposterior view...

Fluoroquinolone (FQ) induced peripheral neuropathies and tendinopathies are well documented, but there are no epidemiologic studies on the risk of carpel tunnel syndrome (CTS). We conducted a case-control study of over 6 million patients. FQ use is associated with increased risk of CTS (RR = 1.34, 95% CI 1.31 - 1.37).

BACKGROUND: In making the decision to undergo carpal tunnel release (CTR), patients may consider probability of symptom resolution. Prior studies have examined potential preoperative variables that might influence the postoperative outcome. Few studies, however, contain the sample size, prospective design, and high participant completion rate to provide solid data from which to counsel patients. The purpose of this study was to prospectively evaluate factors that have been implicated or dismissed in past studies as sources of outcome variation following CTR surgery and provide patient-relatable facts that the surgeon might use in preoperative patient counseling...

Digital nerves are intrinsic to the sensory and motor function of the hand. These nerves represent the terminal ramifications of the ulnar, median, and radial nerves and are located distal to the carpal tunnel and Guyon canal. With magnetic resonance imaging, traumatic and nontraumatic abnormalities of the digital nerves can be shown with high contrast as well as high spatial resolution. Digital nerve abnormalities are most commonly posttraumatic in nature; however, infection, inflammatory, vascular malformations, and neoplasms can rarely occur...

Carpal Tunnel Syndrome (CTS) is the most common form of entrapment neuropathy. Several authors have investigated the anatomical and pathophysiological features of CTS and have identified several parameters that, in combination, play a significant role in its pathophysiology. Advancement in biological research on CTS has enabled the advent of efficient diagnostic techniques such as provocative tests and nerve conduction studies. Sophisticated technologies, such as magnetic resonance imaging (MRI) and ultrasonography (US), have facilitated the diagnosis of CTS...

Transthyretin-derived (ATTR) amyloidosis is a frequent finding in carpal tunnel syndrome. We tested the following hypotheses: the novel fluorescent amyloid ligand heptameric formic thiophene acetic acid (h-FTAA) has a superior sensitivity for the detection of amyloid compared with Congo red-staining; Amyloid load correlates with patient gender and/or patient age. We retrieved 208 resection specimens obtained from 184 patients with ATTR amyloid in the carpal tunnel. Serial sections were stained with Congo red, h-FTAA and an antibody directed against transthyretin (TTR)...

Background Flexion and extension of the wrist is achieved primarily at the radiocarpal and midcarpal joints. Carpal kinematics have been investigated, although there remains no consensus regarding the relative contribution of each bone to wrist motion. Purpose To determine the kinematics of the scaphoid, lunate, and capitate during unconstrained simulated wrist flexion/extension and to examine the effect of motion direction on the contribution of each bone. Materials and Methods Seven cadaveric upper extremities were tested in a passive wrist simulator with 10N tone loads applied to the wrist flexors/extensors...

It is widely hypothesized that mechanical loading, specifically repetitive low-intensity tasks, influences the inner structure of cancellous bone. As such, there is likely a relationship between handedness and bone morphology. The aim of this study is to determine patterns in trabecular bone between dominant and non-dominant hands in modern humans. Seventeen healthy patients between 22 and 32 years old were included in the study. Radial carpal bones (lunate, capitate, scaphoid, trapezium, trapezoid, 1st, 2nd and 3rd metacarpals) were analyzed with high-resolution micro-computed tomography...

INTRODUCTION: Carpal tunnel syndrome (CTS) is a nonspecific manifestation of hereditary ATTR amyloidosis (ATTRm). Amyloid deposition of wild-type TTR (WT-ATTR) has been found in transverse carpal ligament (TCL) in idiopathic CTS. We retrospectively studied a group of patients with ATTRm and CTS submitted to carpal tunnel release surgery (CTRS). METHODS: From the nerve conduction studies performed in our Clinical Unit dedicated to hereditary amyloidosis between July 2009 and October 2013, we selected patients who fulfilled neurophysiological criteria for CTS, had been submitted to CTRS and whose TCL was available for pathology...

Importance: Despite increased focus on reducing opioid prescribing for long-term pain, little is known regarding the incidence and risk factors for persistent opioid use after surgery. Objective: To determine the incidence of new persistent opioid use after minor and major surgical procedures. Design, Setting, and Participants: Using a nationwide insurance claims data set from 2013 to 2014, we identified US adults aged 18 to 64 years without opioid use in the year prior to surgery (ie, no opioid prescription fulfillments from 12 months to 1 month prior to the procedure)...
