Revision internal fixation for femoral-neck nonunion is a challenging procedure. Treatment options are osteotomy, osteosynthesis using various implants and grafting techniques (muscle pedicle, vascularised or nonvascularised fibular graft) or arthroplasty. The objective of this article is to report the outcome of revision internal fixation using an angle blade plate and autogenous fibular graft in symptomatic aseptic femoral-neck nonunion. ⋯ Angle blade plate provides rigid stability and offloads any shearing force over the fibular graft when used for revision internal fixation in aseptic femoral-neck nonunion. Thus, the fibular graft only serves the purpose of osteogenesis and stimulates the surrounding host cells to promote healing at the nonunion site. We recommend the angle blade plate and autogenous fibular graft as a viable option for hip-joint salvage in revision internal fixation of aseptic femoral-neck nonunion.

We evaluated the usefulness of percutaneous reduction and leverage fixation using K-wires in children with radial neck fractures. ⋯ Percutaneous reduction and leverage fixation using K-wires in children with radial neck fractures is a recommended surgical treatment that can achieve recovery of normal radial angulation and elbow motion.

To investigate the correction effectiveness, incidence rate of distal adding on, and post-operative spinal balance in Lenke 3C and 6C AIS treated with extensive fusion using posterior pedicle screw-only constructs. ⋯ In Lenke 3C and 6C scoliosis, extensive fusion can produce satisfactory corrections from the perspectives of both Cobb angle and vertebral translation and rarely causes significant distal adding-on, global imbalance or trunk shift.

The purpose of this study was to determine the location of the anterior humeral circumflex artery and axillary nerve based on bony landmarks, and to provide anatomical information that enables a safe approach when treating a proximal humeral fractures. ⋯ The artery is located approximately 5.1 cm below the inferior border of the medial acromion and 2.5 cm below the prominence of the lesser tuberosity, and the nerve was located approximately 6.3 cm below the anterio-inferior border of the acromion and 3.5 cm below the prominence of the greater tuberosity. The reduction manoeuvres should be conducted with extreme care in this region.

Patellar height is an important factor in patellar tracking and alters the force of the patellofemoral joint reaction. Several methods for measuring patellar height ratio have been described, with no single method recognised as a gold standard. This study developed a new measurement method using a distal femoral reference, where the normal values of measurement are unaffected by varying angles of knee flexion. ⋯ The new patellar height ratio measurement method proved to be accurate and reproducible for evaluating a normal population. This method offered the benefit of using the distal femur as a reference landmark, and, thus, the resulting measurements were not altered by varying degrees of knee flexion.
