A muscle cramp is a painful tightness in a muscle due to a sudden, involuntary contraction. Various factors may contribute to muscle cramping, but the underlying cause is often unclear. Muscle cramps are mostly temporary and go away on their own. Some home remedies may help longer lasting cramps pass or ease the symptoms.
Mid-term data show that today’s dual mobility constructs can provide excellent stability and range of motion in primary and revision total hip arthroplasty when patients are at a higher risk for dislocation. Modern implant designs have successfully mitigated several major failure mechanisms in older systems.
Disparities in unilateral total knee arthroplasty (TKA) have been well-documented, with lower utilization and higher complication rates found among African American patients. Less is known, however, about whether these racial variations are seen with same-day bilateral TKA as well. In a study presented at ACR Convergence 2020, the annual meeting of the American College of Rheumatology, researchers from Hospital for Special Surgery (HSS) showed that African American patients are less likely to undergo same-day bilateral TKA, but when they do, complication rates are not higher than in white patients.
Surgical techniques to treat recurrent shoulder instability are effective but prone to non-union of bone grafts held in place by screws alone. A study published online by The Journal of Bone & Joint Surgery suggests that a new technique – borrowing a design used for centuries in Chinese architecture and woodworking – can provide an effective approach to shoulder stabilization.
