BACKGROUND: The decision to perform endoscopic versus the mini-open carpal tunnel release technique is most likely left to surgeons rather than patients with idiopathic carpal tunnel syndrome. QUESTIONS/PURPOSES: We hypothesized that (1) at 3 months after surgery, the subjective outcomes of endoscopic release, performed on one hand, and mini-incision release, performed on the other, would not differ in patients with bilateral carpal tunnel syndrome; however, (2) each patient would likely prefer

BACKGROUND: Arthroscopic management of scaphoid nonunions has been advanced as a less invasive technique that allows evaluation of associated intrinsic and extrinsic ligamentous injuries; however, few studies have documented the effectiveness of arthroscopic treatment of scaphoid nonunions and which intraarticular pathologies coexist with scaphoid nonunions. QUESTIONS/PURPOSES: (1) What are the outcomes of arthroscopic management of scaphoid nonunions as assessed by the proportion of patients ac

PURPOSE: To compare union rates and clinical and radiologic outcomes after arthroscopic and open bone grafting and internal fixation for unstable scaphoid nonunions. METHODS: Between March 2009 and November 2014, patients with unstable scaphoid nonunion underwent arthroscopic (group A) or open (group O) bone grafting and internal fixation. One senior surgeon alternatively performed either arthroscopic or open osteosynthesis for the same surgical indications. Visual analog scale score, grip stren

The purpose of this study was to compare the outcome and complications of endoscopic versus open release for the treatment of de Quervain's tenosynovitis. Patients with this condition were randomised to undergo either endoscopic (n = 27) or open release (n = 25). Visual Analogue Scale (VAS) pain and Disabilities of Arm, Shoulder, and Hand (DASH) scores were measured at 12 and 24 weeks after surgery. Scar satisfaction was measured using a VAS scale. The mean pain and DASH scores improved signific

BACKGROUND: The symptoms in carpal tunnel syndrome (CTS) can be ameliorated by open and endoscopic release of the transverse carpal ligament. It is unknown whether a mini-incision or endoscopic carpal tunnel release more effectively reverses the pathological changes that are observed in the median nerve in patients with CTS and these morphologic changes correlates with the subjective outcomes after carpal tunnel release. We hypothesized that (1) at 24 weeks after surgery, the subjective outcomes

PURPOSE: To compare union rates and clinical and radiological outcomes of arthroscopic-assisted reduction and fixation with those of open reduction and fixation in patients with trans-scaphoid perilunate fracture dislocations. METHODS: This retrospective study included consecutive patients with trans-scaphoid PLFDs who underwent arthroscopic-assisted reduction and fixation (group A) or open reduction and fixation (group O), and who were followed up for a minimum of 2 years between May 2005 and M

PURPOSE: To compare clinical and radiologic outcomes and complication rates of the arthroscopic wafer procedure (AWP) and ulnar shortening osteotomy (USO) for idiopathic ulnar impaction syndrome (UIS). METHODS: From May 2009 to June 2014, 42 patients who were aged 45 years or older with idiopathic UIS underwent either the AWP or USO under the following identical surgical indications: (1) less than 4 mm of positive ulnar variance, (2) Palmer classification 2C or 2D lesion of the triangular fibroc

Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

An ulnar nerve stability-based approach to surgery selection for cubital tunnel syndrome was effective based on 2-year follow-up data. Older age, worse preoperative grip strength, and worse two-point discrimination were associated with worse outcomes at 2 years.

BACKGROUND: Dorsal wrist ganglions are one of the most frequently encountered problems of the wrist and often are associated with intraarticular disorders. However, it is unclear whether coexisting intraarticular disorders influence persistent pain or recurrence after arthroscopic resection of dorsal wrist ganglions. QUESTIONS/PURPOSES: We investigated (1) which intraarticular disorders coexist with dorsal wrist ganglions and (2) whether they influenced pain, function, and recurrence after arthr

BACKGROUND: Tardy ulnar nerve palsy is a common late complication of traumatic cubitus valgus deformity. Whether both problems can be corrected together, safely and effectively, in a single surgical procedure remains unknown. QUESTIONS/PURPOSES: We therefore reviewed a patient cohort having this combined surgery and compared preoperatively and at a minimum of 24 months postoperatively (1) active elbow ROM; (2) radiographic correction of the cubitus valgus deformity of the preoperative and postop

Background: Osteoarthritis (OA) is a multifactorial disease involving inflammatory processes. Platelets play important roles in both hemostasis and the inflammatory response; however, the relationship between platelet count and OA is unclear. Our aim was to evaluate the association between platelet count and knee and hip OA in Korean women. Methods: In this cross-sectional designed study, we included a total of 6011 women aged ⩾50 years from the 2010–2013 Korea National Health and Nutrition Exam

OBJECTIVE: The purpose of this study was to compare the clinical outcomes of ulnar nerve stability-based surgery via a small incision with those of classic anterior transposition of the ulnar nerve for cubital tunnel syndrome. METHODS: From March 2008 to December 2013, 107 patients with cubital tunnel syndrome underwent simple decompression or anterior transposition via a small incision, according to an ulnar nerve stability-based decision based on an assessment of intraoperative ulnar nerve sta
