AbstractThe elbow is a complex joint made up of three separate articulations within a common capsule. The proximal ulna articulates with the trochlea and functions as a hinge joint, while the proximal radioulnar joint provides for rotational movement of the forearm. The radiocapitellar joint allows for both hinge and rotational movements. Together, these allow for flexion and extension of the arm and, in conjunction with the distal radioulnar joint at the wrist, pronation and supination as well.

Loss Of Motion

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.

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.

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

Abstract Background The arthroscopically assisted Sauvé–Kapandji (S-K) procedure has been described as a safe and promising technique for distal radioulnar joint (DRUJ) arthrodesis. Our purpose was to investigate the advantages and disadvantages of the arthroscopically assisted S-K procedure. Methods Eight patients underwent an arthroscopically assisted S-K procedure. All patients were diagnosed as DRUJ osteoarthritis (OA), including six primary DRUJ OA, one OA following a distal radius fracture, and one rheumatoid arthritis (RA). Arthroscopy was performed in neutral forearm rotation with vertical traction. The surface of the DRUJ was debrided through arthroscopy to expose the subchondral surface, and the DRUJ was fixed with a cannulated screw and Kirschner wire (K-wire) with zero or minus ulnar variance in the same posture. Bone graft was not performed. Results Bone union was achieved at 2 to 3.5 months postoperatively. At an average of 17-month follow-up, the pain intensity on 10-point numerical rating scale (NRS) decreased from 10 preoperatively to 0.4 postoperatively, average range of pronation significantly improved from 77 degrees to 89 degrees, and average grip strength as a percentage of contralateral side improved from 76 to 104%. Conclusion Satisfactory outcomes were achieved with the arthroscopically assisted S-K procedure. Advantages of this procedure included the ability to achieve union without bone grafting, preservation of the extensor mechanism integrity, and easy reduction of the ulnar head due to its wrist positioning. No major complications were encountered. Disadvantages included its required use of arthroscopic technique and potential contraindication for cases with severe deformity at the sigmoid notch. Level of Evidence This is a Level IV, therapeutic study.
