Surgery of the Wrist

A hockey stick incision is made centred on the scaphoid tubercle. Proximally the incision follows the line of the FCR tendon. On reaching the tubercle it is angled along the line of the first metacarpal. If a distal radius bone graft is planned, the proximal limb is lengthened.
Radiogrammetry
Published in Stanton H. Cohn, Non-Invasive Measurements of Bone Mass and Their Clinical Application, 2020
These views are supported by our own observations.13Virtually no vertebral compressions or femoral neck fractures were found in those women whose bone mass in the radius (or cortical thickness, Figures 3, 4, and 24) was above the mean value of the young normals in the 20- to 45-year age range.The incidence of fractures among those whose radial bone mass was between the mean and −2 SD, was low (Figure 24).The incidence of vertebral compressions in those with a bone mass less than 2 SD of the mean of young normals increased steadily and markedly with decreasing bone mass. The group with the thinnest bones showed an incidence of 67% (Figure 24).
Congenital anomalies of the oesophagus

Which of the options listed above is the most appropriate next diagnostic investigation in relation to the following clinical presentations? Each option may be used once, more than once, or not at all. A neonate with OA is seen to have a missing radial bone on extremity X-rays.A 6-hour-old newborn choking and coughing on initiation of feeds.A neonate with OA passing meconium per urethra.

The radial artery is located between the radial bone of the wrist and the skin and is surrounded by muscles. A simple type of radial artery model was developed with reference to an image of a transverse section through the wrist (Figure 1). This model consisted of the radial artery, skin, muscle, radial bone, and ulna bone. The diameter of the radial artery was approximately 3 mm, similar to the typical radius of the radial artery (2.4 ∼ 2.8 mm) (Girerd et al. 1998; Riley et al. 1992), and the skin thickness was 2 mm, which was the skin thickness provided by previous studies. Although the body outside the radial artery, skin, and bone is composed of various types of muscle, nerve, and tissue aggregates, this study assumed that the region consisted only of muscles.
Finite element analysis of bone mechanical properties using MRI-derived bound and pore water concentration maps

From a representative cadaver arm, cross-sectional UTE, AIR, and DAFP MRI images at the distal-third site are shown in Figure 3. The UTE image (left) was cropped to show the cross-sectional image of the arm and the red box indicates the location of the radius bone. Maps of Cbw and Cpw within the radius are overlaid on the corresponding AIR and DAFP images, respectively. Across all 35 bones, the median ± standard deviation of the mean Cbw and Cpw, calculated at middle slice, were 15.37 ± 4.22 mol 1H/Lbone and 14.98 ± 9.34 mol 1H/Lbone, respectively.

A 51-year-old male suffered with a traffic injury which resulted in radial artery injury and fracture of the radial bone and ulnar bone on the left forearm. An external fixator was applied and radical debridement was performed before the reconstruction. Radical debridement left a through-and-through defect. A Design Type C pattern of VL muscle-chimeric multi-lobed ALTP flap was used for the reconstruction of the wound. The size of the dual-skin paddles was 11 cm × 5 cm and 15 cm × 9 cm. The VL muscle flap measuring 9 cm × 5 cm was harvested to obliterate the dead space (Figure 4). The recipient-site and donor-site wounds healed uneventfully.
