The Stability

Background: The brachioradialis (BR) wrap technique is an option to restore the stability of the distal radioulnar joint (DRUJ). The technique capitalizes on the BR’s advantageous insertion point on the radial styloid and the ability of the BR to be harvested with minimal to no deficit. The tendon can then be wrapped around the radius and ulna, tunneling under the pronator quadratus and extensor compartments and secured back into its insertion to provide stability. In this cadaveric study, we used micro-computed tomography (CT) to assess the stability restored by this procedure. Methods: Axial CT scans were taken of cadaveric specimens (n = 10) in 3 different positions (neutral, 60° pronation, and 60° supination) to establish the baseline measurements of each DRUJ. Surgical disruption of the dorsal and volar ligaments of each DRUJ then simulated a destabilizing injury and the specimens were scanned again. The specimens then underwent the BR wrap procedure and were scanned once more. Degree of ulnar subluxation with respect to the Sigmoid notch was determined using the modified radioulnar line method. Results: The mean percentages of subluxation in the neutral position for the normal, injured, and reconstructed DRUJ were 22.4±4.9%, 56.2±12.9%, and 29.0±6.5%, respectively. In 60° pronation, these values were 15.4±4.7%, 53.5±15.0%, and 36.5±11.8%, respectively. In 60° supination, these values were 18.6±2.5%, 69.7±20.5%, and 31.9±8.7%, respectively. Conclusions: Values differed significantly between normal and injured conditions in all positions. No significant difference was noted between normal and reconstructed conditions, suggesting reconstruction improves DRUJ biomechanics and more closely approximates normal stability.

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.

Relationship between dorsal tilt of the distal radius and distal radioulnar joint stability was examined. Stiffness in dorsopalmar displacement of the radius (distal radioulnar joint stiffness) was recorded at 10° intervals until 30° of dorsal angulation from 10° of palmar tilt. Tests were repeated after partial sectioning of the radioulnar ligament, then after complete sectioning of the radioulnar ligament. All data were compared with control (intact triangular fibrocartilage complex, 10° of palmar tilt). The distal radioulnar joint stiffness in dorsal translation decreased significantly with dorsal tilt 10° and 20° in pronation. Partial sectioning of the radioulnar ligament indicated a decrease of the distal radioulnar joint stiffness in the dorsal translation at neutral tilt to 20° of dorsal tilt in the neutral position and in pronation. Distal radioulnar joint stiffness decreased significantly in both dorsal and palmar translations in all forearm positions at 10° and 20° of dorsal tilt. From these findings, the dorsal angulation of the radius should be corrected to less than 10° of dorsal tilt.

The Stability

The distal radioulnar joint allows the human to rotate the forearm to place the hand in a desired position to perform different tasks, without interfering with the grasping function of the hand. The ulna is the stable part of the forearm around which the radius rotates; the stability of the distal radioulnar joint is provided by the interaction between ligaments, muscles and bones. The stabilizing structures are the triangular fibrocartilage complex, the ulnocarpal ligament complex, the extensor carpi ulnaris tendon and tendon sheath, the pronator quadratus, the interosseous membrane and ligament, the bone itself and the joint capsule. The purpose of this review article is to present and illustrate the current understanding of the functional anatomy and pathomechanics of this joint.

Triangular Fibrocartilage

We describe an arthroscopic rein-type capsular suture that approximates the triangular fibrocartilage complex to the anatomical footprint, and report the results at a minimum 12 month follow-up. The procedure involves two 3-0 polydioxanone horizontal mattress sutures inserted 1.5 cm proximal to the 6-R and 6-U portals to obtain purchase on the dorsal and anterior radioulnar ligaments, respectively. The two sutures work as a rein to approximate the triangular fibrocartilage complex to the fovea. Ninety patients with Type IB triangular fibrocartilage complex injuries were included retrospectively. The 12-month postoperative Modified Mayo Wrist scores, Disabilities of Arm, Shoulder and Hand scores and visual analogue scale for pain showed significant improvements on preoperative values. Postoperative range of wrist motion, grip strength and ultrasound assessment of the distal radioulnar joint stability were comparable with the normal wrist. The patients had high satisfaction scores for surgery. There were minor complications of knot irritation. No revision surgery for distal radioulnar joint instability was required. It is an effective and technically simple procedure that provides a foveal footprint contact for the triangular fibrocartilage complex. Level of evidence: IV

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 Relationship

We investigated the relationship between the radial inclination of the distal radius and distal radioulnar joint stability. Six fresh-frozen upper extremities were used. Radial inclination was decreased by 10° and 20° and increased by 10° from the original radial inclination. Distal radioulnar joint stiffness was assessed with an intact radioulnar ligament and after partial and then complete sectioning of the radioulnar ligament. Radial angulation deformities significantly increased distal radioulnar joint stiffness when the radioulnar ligament is totally or partially attached to the ulnar fovea. After complete sectioning of the radioulnar ligament, distal radioulnar joint stiffness decreased significantly; additional radial angulation deformity slightly increased distal radioulnar joint stiffness, but the distal radioulnar joint never recovered to the original stiffness. Based on the results, radial angulation deformities of the distal radius should be corrected within 10° when the radioulnar ligament is intact, to reduce the risk of symptomatic distal radioulnar joint instability.

Graft Rupture

This retrospective study investigated the clinical outcomes of patients treated for chronic distal radioulnar joint instability with open anatomic reconstruction of the palmar and dorsal radioulnar ligaments. After the midpoint of a tendon graft is anchored at the ulnar fovea, the two graft limbs traverse the distal radioulnar joint. One limb is woven into the palmar wrist capsule and the other is secured to the dorsal wrist capsule and retinaculum to stabilize the joint. Of 30 patients (31 wrists) treated with this technique, 19 were followed longitudinally for a mean of 10 years (range 3–21). In this long-term cohort, there were statistically significant improvements in ulnar-sided wrist pain on the visual analogue scale and in distal radioulnar joint stability on the dorsopalmar stress test. The modified Mayo Wrist Scores were classified as three excellent, 12 good, three fair and one poor. Of the 30 patients studied, failure occurred in four patients, two from graft rupture and two from distal radioulnar joint arthrosis. We conclude that anatomic reconstruction of the palmar and dorsal radioulnar ligaments is an effective treatment for distal radioulnar joint instability and is associated with high satisfaction and durable outcomes.

The Relationship

The relationship between increased volar tilt of the distal radius and distal radioulnar joint stability was examined. Distal radioulnar joint stiffness was recorded at 10° intervals from 10° dorsal angulation to 20° of volar angulation from the anatomical position of the radius. Tests were performed with the intact radioulnar ligament and repeated after partial and then complete sectioning of the radioulnar ligament at the ulnar fovea. With the intact radioulnar ligament, distal radioulnar joint stiffness increased significantly at 10° and 20° of volar angulation. Partial sectioning of the radioulnar ligament resulted in an approximate 10% decrease of distal radioulnar joint stiffness compared with the intact state, but distal radioulnar joint stiffness still increased significantly with greater volar tilt. Complete sectioning of the radioulnar ligament significantly decreased distal radioulnar joint stiffness, and increasing the volar tilt did not result in increased distal radioulnar joint stiffness. These results suggest that volar angulation deformities of the distal radius should be corrected to 10° of volar tilt when the triangular fibrocartilage complex is intact. Level of Evidence: N/A
