We report a rare case of irreducible chronic palmar dislocation of the distal radioulnar joint (DRUJ). This case showed that the dislocated ulnar head was impacted to the palmar cortex of the radius probably due to the dynamic force of the pronator quadratus muscle. Re-attachment of the ulnar styloid and partial resection of the ulnar head were necessary to make the reduction of the DRUJ possible. The continuity of the radioulnar ligament to the ulnar head was restored and the stability of DRUJ was maintained after reduction.

Macroscopic Fracture

Acute plastic bowing is an incomplete fracture with a deformation that shows no obvious macroscopic fracture line or cortical discontinuity. Although cases of acute plastic bowing of the ulna with a dislocation of the radial head have been previously reported, we present here a rare case of acute plastic bowing of the radius with a distal radioulnar joint injury in a 16-year-old boy. Internal fixation of the detached fragment to the ulnar styloid and repair of the triangular fibrocartilagenous complex resulted in the disappearance of wrist pain. In cases of distal radioulnar joint injuries in children or adolescents, radiographs of the entire forearm should be taken to evaluate the existence of radial bowing.

Excision Arthroplasty

Bone adaptation after excision arthroplasty of distal radioulnar joint in an acute traumatic distal ulna fracture has never been reported. A case of irreparable and comminuted distal ulnar head fracture was managed by excising the ulna head and repairing the fovea (deep ligament) attachments of distal radioulnar ligaments, and then an unexpected remodeling of the distal ulna with the shape of pole and seat was noted. The anatomy of deep fibers of distal radioulnar ligament is important not only in biomechanics about the stability of distal radioulnar joint but it is also possible in the morphology about the shape of the distal radioulnar joint.

Pronator Quadratus Muscle

The pronator quadratus muscle transfer combined with the Sauvé-Kapandji procedure was used to treat the distal radioulnar joint disorder in ten rheumatoid wrists for prevention against instability of the proximal ulnar stump. All patients were female with a mean age of 46.6 years. The mean follow-up time was 24.2 months. Postoperatively, supination increased in all patients with a mean of 50 degrees. Pain decreased significantly and none complained of prominence of the proximal ulnar stump in normal pronated position and during a tight grip. The wrist radiographs of both coronal and sagittal planes in normal and stress fisting views were used to evaluate the postoperative static and physiologic loaded stability of the proximal ulnar stump. It had shown this procedure provided good static proximal ulnar stump stability in both coronal and sagittal planes. However, in physiologic loaded condition, it was able to provide stability only in the sagittal plane.

The advantage of preserving the distal radioulnar joint in wrist disarticulation is that full forearm rotation is possible if the joint is intact, which improves the capability of the amputee. The Sauvé-Kapandji procedure has been performed to treat rheumatoid or post-traumatic chronic instability and/or arthritis of the distal radioulnar joint. We report a patient with wrist disarticulation that presented to us with limited supination of the wrist due to an injured distal radioulnar joint. We performed the Sauvé-Kapandji procedure, and the patient could regain functional supination of the forearm without losing the ulnar styloid flare that improved prosthetic suspension. This case suggests that the Sauvé-Kapandji procedure can be performed to maintain the advantage of wrist disarticulation even when the initial trauma involves an irreparable injury of the distal radioulnar joint.

Triangular Fibrocartilage

Traumatic hypersupination injury of the distal radioulnar joint is a rare injury, and occurs when sufficient supination force is applied to the joint so as to tear the volar radioulnar ligament, resulting in separation of the triangular fibrocartilage complex, and subluxation of the tendon of extensor carpi ulnaris. This allows the distal ulna to rotate such that the ulnar styloid comes to lie adjacent to the ulna notch of the radius. Treatment of this injury requires manipulation of the joint, under anaesthesia or sedation. We describe a case where posttraumatic radiological investigation of a patient with an anatomical variation of the wrist when in supination resembled a traumatic hypersupination injury of the distal radioulnar joint. A review of the literature has revealed this to be the first reported case of this type.

We report a rare case of Galeazzi fracture-dislocation with an irreducible distal radioulnar joint. The cause of the irreducibility was entrapment of a fragment avulsed from the fovea of the ulna. The patient was successfully treated with open reduction and internal fixation of the radius, ulnar styloid process and avulsed fracture at the fovea of the ulna.

Pronator Quadratus Muscle

The pronator quadratus muscle has been neglected to a great extent in the anatomical and functional literature. This study confirms the consistent presence of two distinct heads to the muscle, and defines the gross and microscopic anatomy. The functional significance of these heads has been studied using in vitro and in vivo techniques to demonstrate that the superficial head is the prime mover in forearm pronation, and that the deep head is a dynamic stabilizer of the distal radioulnar joint.
