| | The Radius and Ulna |
 | | The most medial of the five superficial muscles, the origin is from the common flexor origin and from the olecranon and posterior ulna. | | | The most medial muscle, extensor carpi ulnaris arises from the commmon extensor origin and from the posterior ulna. | | | The muscle originates distal to the abductor pollicis longus and lies alongside that muscle as the two give rise to their tendons which form the lower (anterior) boundary of the anatomical snuff box. |

| | A medial approach was used for the midpart of the shaft of the ulna and a volar approach for the midpart of the shaft of the radius. | | | Hence, clinically, rotational malunion should be borne in mind when angular deformities cannot fully explain the extent of limited rotation of the forearm. | | | Our aim was to assess the influence of isolated and combined rotational malunion of the radius and ulna on the limitation of rotation of the forearm. |

| | For in those animals the acute process of the epiphysis of the ulna is elongated and has its own depression in the carpal bones; no special cartilage [discus articularis] comes between the ulna and the carpus except the one that covers the bones like a coating. | | | This is partly the result of a system of movement, to prop the radius with its curved shape on the ulna and to move it readily to supine and prone positions. | | | if when the ulna is stationary with respect to the humerus the hand was to be pronated and supinatedwith the benefit and aid of the radius. |

| | Radial Aplasia and Distraction |
| | Premature closure of the ulna physis presumably from the centralization procedure at a young age was responsible for the inability of the affected forearm to keep up with growth. | | | Centralization of the radius, a technique by which the hand-wrist unit is positioned on the end of the ulnar epiphysis, is the most commonly recommended treatment for radial deficiency (radial club hand deformity). | | | Problems of recurrence in fact led Buck-Gramcko (1971) to describe a procedure called radialization in which the carpus is overcorrected on the distal ulna. |

| | Its base is continuous with the body of the bone, and of considerable strength. | | | Ossification begins near the middle of the body, about the eighth week of fetal life, and soon extends through the greater part of the bone. | | | At the junction of this surface with the front of the body is a rough eminence, the tuberosity of the ulna, which gives insertion to a part of the brachialis; to the lateral border of this tuberosity the oblique cord is attached. |

| | DOUBLE WRIST -- ULNA PRESS |
| | Once the basic technique of escaping from the double-wrist hold is mastered, however, this technique is a very simple variation on the Ulna Press. | | | In practice, this technique looks very tricky and quick, because it adds the force of uke attempting to press tori's arms inward to tori's sudden reversal of energy, and because there is a quick change of hands. | | | The move becomes the standard ulna press as outlined previously as soon as tori has achieved a grasp on uke's right wrist with his own right hand, and begins to rotate the arm over using his left hand with the palm up and fingers to the outside, cupping the elbow. |
