Lateral Femoral Closing Wedge Osteotomy in Genu Varum.

Orthop Traumatol Surg Res 2021 Jun 15:102989. Epub 2021 Jun 15.

Orthoprofis Hannover Luisenstraße 10/11, 30539 Hannover, Allemagne.

The distal femoral valgisation osteotomy has a variety of indications due to enhanced understanding of segmental deformities of the lower limb. Historically, an overall varus deformity was corrected at the tibia, and a valgus deformity at the femur. This approach of performing an "all in the tibia" correction for an overall varus can nevertheless lead to abnormal postoperative morphology because it is non-anatomical; creating joint line obliquity, and potentially shear stress on the cartilage.

Osteotomies around the knee lead to corresponding frontal realignment of the ankle.

Eur J Orthop Surg Traumatol 2021 Jun 4. Epub 2021 Jun 4.

Department for Trauma and Reconstructive Surgery, BG Klinik, University of Tübingen, Tübingen, Germany.

Introduction: Despite the fact that osteotomies around the knee represent well-established treatment options for the redistribution of loads and forces within and around the knee joint, unforeseen effects of these osteotomies on the ankle are still to be better understood. It was therefore the aim of this study to determine the influence of osteotomies around the knee on the coronal alignment of the ankle. We hypothesize that osteotomies around the knee for correction of genu varum or valgum lead to a change of the ankle orientation in the frontal plane by valgisation or varisation. Read More

Alkaline phosphatase in pediatric patients with genu varum caused by vitamin D-deficient rickets.

Endocr J 2021 Mar 24. Epub 2021 Mar 24.

Department of Pediatrics, Osaka University Graduate School of Medicine, Osaka, Japan.

An elevated serum alkaline phosphatase (ALP) level is one of the markers for the presence of rickets in children, but it is also associated with bone formation. However, its role in diagnosing genu varum in pediatric patients with vitamin D-deficient rickets is still unknown. To clarify the role of the serum ALP level in assessing the severity of genu varum, we retrospectively investigated this issue statistically using data on rickets such as serum intact parathyroid hormone (iPTH), 25-hydroxyvitamin D, 1,25-dihydroxyvitamin D, ALP, the level of creatinine as the percentage of the median according to age (%Cr), and the metaphyseal diaphyseal angle (MDA) in the lower extremities as an index of the severity of genu varum.
