Level III, prognostic study.

BACKGROUND: The purpose of this study was to compare the clinical outcome of surgery using robot-assisted posterior interbody fusion with that using freehand posterior interbody fusion in patients with degenerative spinal disease. METHODS: 78 participants with degenerative spinal disease were randomly allocated (1:1) to the minimally invasive (MIS), posterior lumbar interbody fusion (Robot-PLIF) or conventional, freehand, open-approach, posterior lumbar interbody fusion (Freehand-PLIF). RESULTS:

Arthroscopic surgery was useful to treat synovial chondromatosis of the hip. In spite of limited removal of loose bodies, arthroscopic procedures including extensive capsulectomy could be effective for the treatment of synovial chondromatosis of the hip.

Rheumatoid arthritis (RA) can cause significant hand and wrist damage and dysfunction. The aim of medical treatment is to eradicate inflammation and prevent damage to joints and soft tissues. Advances in newer biological therapies over the last two decades have resulted in greater remission rates and lower disease activity status. Despite these improvements, surgical intervention is still indicated in cases of disability, irreversible deformities, and severe pain. However, there are large variat

BACKGROUND: Various surgical techniques have been attempted to treat patients with failed anterior subcutaneous transposition performed for cubital tunnel syndrome. OBJECTIVE: To analyze intraoperative findings of failed anterior subcutaneous transposition and to report the outcome of in Situ neurolysis of ulnar nerve. METHODS: Patients who, under diagnosis of failed anterior subcutaneous transposition of ulnar nerve, underwent in Situ neurolysis between 2001 and 2018 were included in this study

Our study suggests that Kienböck's disease diagnosed at more than 50 years of age can follow a benign natural course in radiographic and clinical aspects. Therefore, surgical interventions should be considered carefully in this age group.

During the postoperative hand rehabilitation period, it is recommended that the repaired flexor tendons be continuously glided with sufficient tendon excursion and carefully managed protection to prevent adhesion with adjacent tissues. Thus, finger joints should be passively mobilized through a wide range of motion (ROM) with physiotherapy. During passive mobilization, sequential flexion of the metacarpophalangeal (MCP) joint followed by the proximal interphalangeal (PIP) joint is recommended fo

OBJECTIVE: Index-to-ring finger ratio (IRFR) has been reported to be associated with joint osteoarthritis (OA). We aimed to evaluate the association between IRFR and trapeziometacarpal joint (TMCJ) OA in an elderly Korean population. METHODS: A population-based sample included 604 participants with a mean age of 74.8 years. IRFR was radiographically measured by the ratio of the length of the right second to fourth phalangeal bones ("phalangeal IRFR") and metacarpal bones ("metacarpal IRFR"), and

BACKGROUND: The distribution of subchondral bone density in a joint represents stress that is applied to the joint. Knowing this information is important for understanding the pathophysiology of osteoarthritis (OA). In the elbow, however, this has not been studied before. QUESTIONS/PURPOSES: (1) Is advanced-stage elbow OA associated with more radially distributed subchondral bone density than earlier stages? (2) What demographic (age and sex) and radiographic (osteophyte location and carrying an

Abstract Trapeziectomy is performed for trapeziometacarpal (TMC) arthritis but decreased lateral pinch strength is a major source of discomfort after the surgery. The magnitude of the decrease is unclear, however, and how the pressure changes in the TMC joint is unknown. To investigate this relationship, we designed a cadaveric study to measure TMC joint pressure using a lateral pinch model, and quantitatively evaluated the effect of trapeziectomy on the pressure measurements. For 10 cadaveric f
