A new technique for cement plug removal in hip and knee arthoplasty exchange.

Rev Esp Cir Ortop Traumatol 2021 Jul-Aug;65(4):279-284

Servicio de Cirugía Ortopédica del Hospital Central de la Defensa Gómez Ulla, Madrid, Spain.

Removal of cement and especially the distal cement plug during cemented arthroplasty replacements is key to the success of the surgery, but can be challenging for the surgeon. The methods employed for this step can be very varied, ranging from removal with the aid of rasps, drills, ultrasonic techniques, to bone windows for direct access to the plug. These techniques can sometimes lead to perforation of the bone cortex and even to the production of uncontrolled fractures that prevent safe implantation of the new implant. Read More

Treatment Options for End-Stage Hip Disease in Adolescents: To Replace, Fuse, or Reconstruct?

Eduardo N Novais

J Pediatr Orthop 2021 Jul;41(Suppl 1):S47-S52

Child and Young Adult Hip Preservation, Boston Children's Hospital, Boston, MA.

Introduction: This paper aims to review the indications criteria for the surgical treatment of adolescents with hip osteoarthritis and summarize the contemporary techniques that orthopaedic surgeons can apply for hip reconstruction.

Discussion: Hip osteoarthritis remains a concerning burden to North American society. While the rate of total hip replacement (THR) in younger patients has increased in the last decades, younger patients may have a higher risk of revision hip replacement because of their increased level of activity and expected patient longevity compared with the elderly.

Layered Double Hydroxide Modified Bone Cement Promoting Osseointegration Multiple Osteogenic Signal Pathways.

ACS Nano 2021 Jun 4. Epub 2021 Jun 4.

Department of Orthopedic Surgery, Peking Union Medical College Hospital, Peking Union Medical College & Chinese Academy of Medical Sciences, Beijing, 100730, China.

Poly(methyl methacrylate) (PMMA) bone cement has been widely used in orthopedic surgeries including total hip/knee replacement, vertebral compression fracture treatment, and bone defect filling. However, aseptic loosening of the interface between PMMA bone cement and bone often leads to failure. Hence, the development of modified PMMA that facilitates the growth of bone into the modified PMMA bone cement is key to reducing the incidence of aseptic loosening. Read More
