We examined 248 wrist X-rays of patients over 50 years of age to find out if ulnar variance, orientation of the sigmoid notch and ulnar head inclination play a role in the development of non-traumatic osteoarthritis of the distal radioulnar joint. Minor degenerative changes, viz. focal joint space narrowing and/or lipping, or small osteophytes at the inferior edge of the ulnar head, were present in 13% of the X-rays of these wrists. They were significantly more frequent in wrists with a more inclined ulnar head and significantly less present in wrists with an oblique, distally orientated sigmoid notch. There was no significant association with ulnar variance or age. This study suggests that articular morphology may play a role in the development of degenerative changes of the distal radioulnar joint.

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.

Ulnar Impaction Syndrome

We retrospectively reviewed 26 patients diagnosed with idiopathic ulnar impaction syndrome and measured the slopes of the sigmoid notch and ulnar head at their centre using their preoperative three-dimensional computed tomography. We found that the slope of the sigmoid notch and that of the ulnar head were not parallel to each other. There was a significant linear relation between the slope of the ulnar head and the changes in the closest joint space of the distal radioulnar joint at the centre of the sigmoid notch after ulnar shortening. We conclude that the slope of the ulnar head is more strongly correlated with changes in the closest joint space in the distal radioulnar joint than that of the sigmoid notch. Our findings suggest that slope of the ulnar head might be as important a predisposing factor as that of the sigmoid notch for the progression of distal radioulnar joint arthritis after ulnar-shortening osteotomy. We should consider the slopes of both the sigmoid notch and ulnar head before the osteotomy. Level of evidence: IV

A long ulna, as a result of congenital differential growth, such as Madelung’s disease, or injury, commonly a consequence of a malunited distal radial fracture, may present clinically as pain, decreased motion, mainly of pronosupination, and weakness of grip. Secondary effects may include perforations and tears of the triangular fibrocartilage complex, cartilage wear of the proximal surface of lunate and triquetrum and tears of the lunotriquetral ligament. Positive ulnar variance may be evident on X-rays but a prominent ulnar head cannot always be excluded when there is neutral ulnar variance and further investigations, such as an arthroCTscan or arthroscopy, may be necessary. The two principle treatment options are (a) resection of the distal ulna (Darrach’s and Sauvé –Kapandji’s techniques are commonly used) and (b) techniques preserving the ulnar head, including different modalities of shortening osteotomy. The aim is to regain a congruent distal radioulnar joint, restore painless and normal pronosupination and prevent onset of osteoarthritis of this joint.

And Function

From the interosseous membrane of the forearm a tract extends to the dorsal capsule of the distal radioulnar joint. The structure and function of this tract have been investigated. The tract originates from the radius 22 mm proximal to the distal dorsal corner of the sigmoid notch. Central fibres are attached there with fibrous cartilage and superficial bundles mix with the periosteum. The tract is 8 mm wide, 31 mm long and 1 mm thick. Distally it inserts at the capsule of the distal radioulnar joint between the tendon sheaths of extensor digiti minimi and extensor carpi ulnaris. Deep fibres insert directly at the triangular fibrocartilage. The tract of the interosseous membrane is taut in pronation and loose in supination. It strengthens the dorsal capsule of the distal radioulnar joint. During pronation the tract protects the ulnar head in a sling. Its attachment at the triangular fibrocartilage influences the distal radioulnar joint. Its insertion at the triangular fibrocartilage and the support of the weakest part of the dorsal capsule are of interest.

Posteroanterior radiographs of 102 normal wrists were studied to determine the morphological characteristics of the ulnar head associated with the value of ulnar variance. Ulnar variance, ulnar styloid length, ulnar head diameter, ulnar seat inclination, and the distance of ulnar head peak to the distal radioulnar joint were measured together with the third metacarpal length as a reference of the size of the wrist. Moderate correlation was confirmed not only between ulnar variance and ulnar seat inclination but also between ulnar variance and the distance of the ulnar head peak. Furthermore, we found a statistically significant correlation between ulnar variance and ulnar head diameter. The results showed that whole ulnar head configurations are affected by ulnar variance although there are considerable variations.

Epidemiology Investigation

A 32-year-old woman presented with progressive pain and swelling of the left wrist for 6 months. Physical examination revealed a firm, tender, oval swelling over the left wrist. X-rays showed a pressure effect on the distal radius and ulna. Magnetic Resonance Imaging (MRI) revealed a well-defined, asymmetrical, dumbbell-shaped soft-tissue lesion involving the interosseous region of the distal forearm and extending until the distal radioulnar joint (DRUJ). Core needle biopsy confirmed the diagnosis of desmoid tumour. Marginal excision of the tumour was done. At the 2-year follow-up, the patient was doing well and had painless and improved left wrist motion. Desmoid tumour involving the DRUJ has not been previously reported. We, through this case, report new observation and discuss the epidemiology, investigation of choice, treatment modalities, and the need for a regular follow-up for appendicular desmoid tumours.

Sixty-one wrists in 61 patients with osteoarthritis of the distal radioulnar joint treated by three consecutive procedures (20 Darrach, 25 Sauvé-Kapandji and 16 hemiresection-interposition arthroplastic procedures) were retrospectively evaluated. We preferred to perform Darrach's procedure in even the early stages of osteoarthritis of the distal radioulnar joint prior to introduction of Sauvé-Kapandji and hemirestion-interposition arthroplastic procedures. Subsequently the hemirestion-interposition arthroplasty was indicated when the triangular fibrocartilage cartilage was intact or could be reconstructed and the Sauvé-Kapandji when the triangular fibrocartilage complex could not be reconstructed or there was positive ulnar variance of more than 5 mm even though the triangular fibrocartilage complex was functional. Patient's age at operation averaged 59.8 years. There were 36 men and 25 women. There were 38 primary and 23 secondary osteoarthritis cases. Post-operative pain, range of motion, grip strength, return to work status; and radiographic results were evaluated. At the five- to 14-year (average, ten years) follow-up evaluation, relief of pain from Darrach procedure was inferior to the Sauvé-Kapandji procedure and hemiresection-interposition arthroplasty although this was not statistically significant. After both the Sauvé-Kapandji procedure and hemiresection-inteposition arthroplasty, post-operative improvements in flexion and extension of the wrist had statistical significance. Post-operative improvements in pronation and supination of the forearm showed statistical significances after all procedures. Improvements of post-operative grip strength and return to an original job in the Sauvé-Kapandji procedure and hemiresection-interposition arthroplasty were statistically superior to those with a Darrach's procedure. There were many post-operative complications following the Darrach's procedure. Darrach's procedure is better indicated for severe osteoarthritic changes of the distal radioulnar joint in elderly patients. We believe the operative indications between the Sauvé-Kapandji procedure and hemiresection-interposition arthroplasty are best determined prior to surgery by the existence and status of the triangular fibrocartilage complex and the amount of the positive ulnar variance.

Strenuous Activity

A variety of surgical techniques are used to treat the arthritic distal radioulnar joint, which is influenced by aetiology and previous procedures. Four types of ulnar head arthroplasty exist: total ulnar head, partial ulnar head, unlinked total distal radioulnar joint, and linked distal radioulnar joint. Although long-term outcome studies are sparse, short-term clinical and biomechanical studies have shown encouraging results, leading to expanded indications. Based on our experience and a literature review, patients are advised that pain is improved but minor pain is common after strenuous activity. Ulnar neck resorption is common, however, implant loosening is rare. Sigmoid notch erosion is concerning, but appears to stabilize and not affect outcome. A partial ulnar head replacement that retains bony architecture and soft tissue restraints may have benefit over a total ulnar head in appropriate patients. If appropriate selection criteria are met, ulnar head replacement typically produces reliable results, with low revision.

Abstract Background Measurement of in vivo distal radioulnar joint (DRUJ) pathomechanics during simple activities can represent the disability experienced by patients and may be useful in diagnostics of DRUJ instability. A first step is to describe the physiological normal limits for DRUJ kinematics in a reproducible and precise test setup, which was the aim of this study. Methods DRUJ kinematics were evaluated in 33 participants with dynamic radiostereometry (RSA) while performing a standardized press test examination. AutoRSA software was used for image analyses. Computed tomography (CT) forearm bone models were generated, and standardized anatomical axes were applied to estimate kinematic outcomes including, DRUJ translation, DRUJ position ratio, and changes in ulnar variance. Repeatability of dynamic RSA press test double examinations was evaluated to estimate the precision and intraclass correlation coefficient (ICC) test–retest agreement. Results The maximum force during the press test was 6.0 kg (95% confidence interval [CI]: 5.1–6.9), which resulted in 4.7 mm (95% CI: 4.2–5.1) DRUJ translation, DRUJ position ratio of 0.40 (95% CI: 0.33–0.44), and increase in ulnar variance of 1.1 mm (95% CI: 1.0–1.2). The mean maximum DRUJ translation leveled off after a 5 kg force application. The DRUJ translation ICC coefficient was 0.93 within a prediction interval of ± 0.53mm. Conclusions This clinical study demonstrates the normal values of DRUJ kinematics and reports excellent agreement and high precision of the press tests examination using an automated noninvasive dynamic RSA imaging method based on patient-specific CT bone models. The next step is the application of the method in patients with arthroscopic verified triangular fibrocartilage complex injuries. Level of Evidence This is a Level IV, case series study.

Background Transosseous repair of foveal detachment of the triangular fibrocartilage complex (TFCC) is effective for distal radioulnar joint stabilization. However, studies of the optimal foveal and TFCC suture positions are scant. Purpose The purpose of this study was to clarify the optimal TFCC suture position and bone tunnels for transosseous foveal repair. Materials and Methods Seven cadavers were utilized. The TFCC was incised at the foveal insertion and sutured at six locations (TFCCs 1–6) using inelastic sutures. Six osseous tunnels were created in the fovea (foveae 1–6). Fovea 2 is located at the center of the circle formed by the ulnar head overlooking the distal end of the ulna (theoretical center of rotation); fovea 5 is located 2 mm ulnar to fovea 2. TFCC 5 is at the ulnar apex of the TFCC disc; TFCC 4 is 2 mm dorsal to TFCC 5. TFCC 1 to 6 sutures were then placed through each of the six osseous tunnels, resulting in 36 combinations, which were individually tested. The forearm was placed in five positions between supination and pronation, and the degree of suture displacement was measured. The position with the least displacement indicated the isometric point of the TFCC and fovea. Results The mean distance of suture displacement was 2.4 ± 1.6 mm. Fovea 2, combined with any TFCC location, (0.7 ± 0.6 mm) and fovea group 5, combined with TFCC 4 location (0.8 ± 0.8) or with TFCC 5 location (0.9 ± 0.6) had statistically shorter suture displacements than any other fovea groups. Conclusion For TFCC transosseous repair, osseous tunnel position was more important than TFCC suture location.
