Ulnar Styloid Process

AbstractSymphalangism is a rare genetic condition characterized by ankylosis of the proximal interphalangeal (PIP) or/and distal interphalangeal (DIP) joints. The patient presented with fused bilateral PIP joints and poor flexion, and an unsatisfactory range of motion (ROM) in the metacarpophalangeal (MP) and DIP joints. Concomitantly, multi-carpal coalition, proximal carpal malalignment, and ulnar styloid process abnormality were also observed in radiographs obtained at diagnosis. Rehabilitation training of the MP and DIP joints and a wrist supporter were recommended to achieve MP and DIP functional motion and restrict dramatic wrist motion. This is the first case report of symphalangism with multi-carpal coalition and abnormality of the ulnar styloid process to the best of our knowledge.

Type Of Injury

Isolated volar dislocation of the distal ulna without forearm fracture is very rare; however, this injury is incorrectly diagnosed in approximately 50% of cases. This injury can lead to a significant functional disability if left untreated. This report presents a case of isolated volar dislocation of the distal ulna with an ulnar styloid fracture. The dislocation was subsequently reduced, the styloid was surgically repaired, and the patient was satisfied at the last follow-up. The importance of a proper clinical examination and an accurate radiographic position of the wrist are stressed. Furthermore, clinical evaluation of the distal radioular joint after reduction is important in achieving good results. There are various strategies for the treatment of distal radioulnar joint after reduction, including conservative treatment or surgical treatment. We believe that surgical exploration could have been carried out at an earlier stage had such a lesion been suspected. Additional case reports of other instances of successful treatment are needed to educate orthopaedic surgeons and emergency medical technicians on the nature of this type of injury.

Abstract Background Ulnar styloid fractures can be associated with clinically significant instability of the distal radioulnar joint (DRUJ). However, the exact fragment size that results in DRUJ instability is unknown. Purpose The objective of this study was to determine the critical size of an ulnar styloid fracture that would result in a significant increase in DRUJ translation and forearm rotation. Methods Eight cadaveric specimens were used to investigate the effects of three different ulnar styloid fracture sizes on DRUJ instability: tip fracture, base fracture, and a fracture including the fovea. Forearm rotation and dorsopalmar DRUJ translation were measured after each sequential increase in fracture size. Results Relative to the uninjured state, a significant increase in forearm rotation and dorsopalmar translation was found for all three fractures. However, the fovea fracture showed a statistically significant increase in forearm rotation compared with all other fracture types and a statistically significant increase in total dorsopalmar translation compared with the tip fracture. Conclusion In this study, ulnar styloid fractures involving the fovea resulted in significantly greater DRUJ instability comparted to tip and base fractures alone. This study provides important biomechanical data regarding the critical size of ulnar styloid fractures that result in DRUJ instability and may aid in the surgical decision-making algorithm in these patients.

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.
