Soft Tissue Stabilization of the Hinge Position for Lateral Closing-Wedge Distal Femoral Osteotomy: An Anatomic Study.

Background: Soft tissue plays an important role in stabilizing the hinge point for osteotomy around the knee. However, insufficient data are available on the anatomic features of the soft tissue around the hinge position for lateral closing-wedge distal femoral osteotomy (LCWDFO).

Purpose: To (1) anatomically analyze the soft tissue around the hinge position for LCWDFO, (2) histologically analyze the soft tissue based on the anatomic analysis results, and (3) radiologically define the appropriate hinge point to prevent unstable hinge fracture based on the results of the anatomic and histological analyses.

A case of extrapulmonary tuberculosis after use of baricitinib.

Extrapulmonary tuberculosis (TB) can occur in patients treated with Janus kinase (JAK) inhibitors. We present a case of rheumatoid arthritis complicated by extrapulmonary TB following baricitinib treatment. A 45-year-old Japanese woman was diagnosed with rheumatoid arthritis at another hospital, and she subsequently started treatment with methotrexate (MTX) at 6.

Soft tissue stabilization of the hinge position in medial closed wedge distal femoral osteotomy: an anatomical study.

Background: Soft tissue has an important role in stabilizing the hinge point of medial closed wedge distal femoral osteotomy (MCWDFO). However, there are conflicting data on the soft tissue anatomy around the hinge point of MCWDFO and, therefore, further anatomical data are needed. The purposes of the study were to: 1) anatomically analyze the soft tissue around the hinge point of MCWDFO; 2) radiologically define the appropriate hinge point to prevent an unstable hinge fracture based on the result of the anatomical analysis; and 3) histologically analyze the soft tissue based on the result of the anatomical analysis.

Distal femoral osteotomy for genu valgum deformity caused by malunited Hoffa fracture.

Hoffa fractures are unstable intra-articular fractures of the femoral condyle that occur in the coronal plane.Insufficient anatomical reduction and internal fixation may lead to non-union or malunion. A 39-year-old man was involved in a traffic accident while riding a motorcycle and was diagnosed with left Hoffa fracture and avulsion fracture of the femoral attachment of the medial collateral ligament.
