Background: The objective of this retrospective study was to evaluate the outcomes of ulnar stump stabilization after ulna head resection using the FCU tendon by investigating the rate of postoperative extensor tendon rupture and click on forearm rotation. Methods: Wrist synovectomy (distal radioulnar joint (DRUJ), radiocarpal and midcarpal joints) and ulnar head resection combined with ulnar stump stabilizing procedure were performed in 58 wrists of 53 patients with RA in our hospital. Before operation, the dorsal subluxation ratio (DSR) of the ulnar head was measured with a multi-slice computed tomography (CT) images. The stabilization of ulnar stump after head resection was performed by the value of the DSR or the instability before the operation. Results: There was neither extensor tendon rupture nor click on forearm rotation in all the patients. Smooth forearm rotation was achieved by ulnar head resection and stabilizing procedure for the ulnar stump. The active range of forearm supination and pronation increased significantly from 68° ± 23° (mean ± SD) to 80° ± 10°, and from 69° ± 17° to 74° ± 13°. The grip power increased from 117 ± 62 mmHg to 185 ± 55 mmHg. In the assessment using 3DCT, the preoperative DSR of 54% improved to 8% on the whole (n = 58). In the wrists with extensor tendon rupture (n = 36), the preoperative DSR of 58% improved to 12%. In the wrists without tendon rupture (n = 22), the preoperative DSR of 46% improved to 2%. Conclusions: The operative technique of ulnar stump stabilization using the FCU tendon was one of the suitable procedure to prevent complications after ulnar head resection.

Non-rheumatoid osteoarthritis of the distal radioulnar joint can cause extensor tendon rupture. We analysed the radiographic morphology of the distal radioulnar joint to identify the risk factors for this complication. Forty-one wrist X-rays of 37 patients with extensor tendon rupture caused by distal radioulnar joint osteoarthritis were evaluated retrospectively for the severity of osteoarthritis by the Kellgren/Lawrence scoring system. Measurements were obtained from posteroanterior views. All but one wrist had severe osteoarthritic changes exceeding grade 3. The radiographic features that were different from those of the contralateral wrists included deepening and widening of the sigmoid notch, radial shift of the ulnar head and dorsal inclination of the sigmoid notch. There was no significant association between tendon rupture and the morphology of the ulnar head or ulnar variance. The scallop sign, dorsal inclination of the sigmoid notch and radial shift of the ulnar head are radiological risk factors for extensor tendon ruptures.

Abstract Background Previous study demonstrated that distal radioulnar joint (DRUJ) plays a biomechanical role in extension and flexion of the wrist and suggested that fixation of the DRUJ could lead to loss of motion of the wrist. Little is known about the pre- and postoperative range of motion (ROM) after the Sauvé–Kapandji (S-K) and Darrach procedures without tendon rupture. To understand the accurate ROM of the wrist after the S-K and Darrach procedures, enrollment of patients without subcutaneous extensor tendon rupture is needed. Purpose This study aimed to investigate the pre- and postoperative ROM after the S-K and Darrach procedures without subcutaneous extensor tendon rupture in patients with rheumatoid arthritis (RA) and osteoarthritis (OA). Methods This retrospective study included 36 patients who underwent the S-K procedure and 10 patients who underwent the Darrach procedure for distal radioulnar joint disorders without extensor tendon rupture. Pre- and postoperative ROMs after the S-K and Darrach procedures were assessed 1 year after the surgery. Results In the S-K procedure, the mean postoperative ROM of the wrist flexion (40 degrees) was significantly lower than the mean preoperative ROM (49 degrees). In wrist extension, there were no significant differences between the mean preoperative ROM (51 degrees) and postoperative ROM (51 degrees). In the Darrach procedure, the mean postoperative ROM of the wrist flexion and extension increased compared with the mean preoperative ROM; however, there were no significant differences. Conclusion In the S-K procedure, preoperative ROM of the wrist flexion decreased postoperatively. This study provides information about the accurate ROM after the S-K and Darrach procedures. Level of Evidence This is a Level IV, therapeutic study.

The first imaging modality in patients suspected of distal radioulnar joint pathology should be conventional radiography to exclude or diagnose wrist pathology including osteoarthritis, rheumatoid arthritis, calcium pyrophosphate deposition disease, (healed) fractures, or impaction syndromes. When conventional radiography is inconclusive, high resolution 3 Tesla magnetic resonance imaging is advised. We provide a broad overview of the literature regarding the use of intra-articular contrast both with computed tomography (CTA) or magnetic resonance imaging (MRA). Conventional arthrography and unenhanced computed tomography are not indicated. This article discusses the most useful imaging techniques in terms of clinical indications, patient positioning, technical imaging requirements, and diagnostic performance in patients with suspected distal radioulnar joint pathology. Furthermore, the most prevalent pathologies are discussed, with the focus on imaging characteristics in both stable and unstable distal radioulnar joints.
