Delayed treatment of volar dislocation of the distal radioulnar joint can result in wrist pain, limited rotation of the forearm, and degenerative arthritis that could be managed only by salvage procedures. A 24-year-old male patient presented with wrist pain and a loss of forearm rotation after surgery for a radial shaft fracture. The shaft of the radius was fixed with a plate and screws with a volar angulation of 7°. The ulnar head was dislocated volar to the distal radius, and the bone defect in the ulnar head was impacted into the volar rim of the sigmoid notch of the radius, preventing the head from being reduced in the joint. Corrective osteotomy of the malunited radial shaft and sliding osteotomy of the proximal ulnar head were performed to fill the distal bone defect. Pain and range of the forearm rotation were improved at postoperative 19 months.

After volar locking plating of distal radius fracture, complications arising from unrecognized dorsally prominent screws penetrating the extensor compartments are increasingly reported. However, standard radiography and fluoroscopy may not adequately visualize screw lengths, because of complex shape of dorsal cortex of the distal radius. We presented case of ultrasonography diagnosis of extensor tenosynovitis caused by dorsal screw prominence after volar plate fixation of distal radius fracture.

Late rupture of the extensor pollicis longus (EPL) tendon is an occasional complication following a distal radius fracture. Early rupture of the EPL tendon as a complication of distal radius fracture is rare. We report one case of early rupture of the EPL tendon after distal radius fracture.

Purpose: The aim of this study was to assess the effectiveness of domestically developed volar locking plate which has the concept of double-tiered subchondral support (DSS) in maintaining the reduction after distal radial fracture surgery. Materials and Methods: From July 2017 to December 2018, 54 patients were assessed. Plain radiographs were obtained immediately after surgery and at the last follow-up, and the radiographic parameters were measured in those images: radial length, radial inclination, volar tilt, ulnar variance, and distal dorsal cortical distance. The patients were subdivided into their age, type of fracture, and the position of the plate to evaluate the influence of each factors on the reduction maintenance. Results: Distal dorsal cortical distance in radiographs after the surgery was 5.91 mm (standard deviation, ±1.95 mm) on average. Significant differences in the radial length (p=0.038) and ulnar variance (p=0.001) were observed between immediately after surgery and at the last follow-up. When the parameters were evaluated by dividing the patients into subgroups according to the three specific factors, the ulnar variance showed a significant increase at the last follow-up when the patients were included 65-years-old or older. AO/OTA type C3 fracture, and Soong classification grade 0 plate position (p=0.007, p=0.012, p=0.046, respectively). Conclusion: Using the domestically developed DSS-type volar locking plate, significant reduction after distal radial fracture surgery could be maintained successfully. On the other hand, further study will be needed to determine about the reduction loss of the lunate facet identified in special cases that deal with fractures in elderly patients, unstable AO/OTA type C3 distal radial fractures, and Soong classification grade 0 plate position.

Purpose: We wanted to evaluate the result of percutaneous, mini-open reduction for the treatment of Mason II or III radial head and neck fractures. Materials and Methods: 13 patients (8 male, 5 female) with Mason II or III radial head and neck fractures were treated by 1 cm percutaneous mini-open reduction under fluoroscopy. The average age of our subjects was 29 years. Follow up duration was 18 months. Results: Union was noted in all cases. Mean radial neck angulation was decreased from 33.2 degrees to 7.8 degrees. The mean change in angulation between the immediate post-operative and last follow-up was 0.7 degrees. The mean range of motion at the elbow joint was at last follow up, 133.1 degrees in flexion, 7.3 degrees in extension, 80 degrees in pronation and 84.3 degrees in supination. Postoperatively, mean Mayo Elbow Performance Index, American Shoulder and Elbow Surgeons elbow score, and Disabilities of the Arm, Shoulder and Hand score were 96.2, 97 and 1.2. Temporary posterior interosseous nerve palsy (1 case) and minimal cubitus valgus deformity (1 case) were noted. Conclusion: Selected Mason II or III radial head and neck fractures can be treated satisfactorily with percutaneous mini-open reduction.

A 1-year-old, castrated male Yorkshire terrier (case 1) and a 7-year-old female Poodle (case 2) presented with delayed union fractures. In case 1, the dog had a fractured right distal radius and ulna. In case 2, the dog had a fractured left distal tibia and fibula. A physical examination and radiographs performed in both dogs revealed delayed union fractures with large gaps. The fracture sites were fixed by bone plate and screws. Autogenous cancellous bone graft was applied into the fracture gap. To encourage rapid bone union, we used matrigel containing $20{\mu}g$ of recombinant human bone morphogenetic protein-2 (rhBMP-2) in the fracture site. Radiographs were taken postoperatively to monitor healing. Rapid bone union was noted in both dogs in long-term radiographs. In case 1, the radiographs revealed that the fracture gaps of the radius and ulna were bridged at 2 weeks. Fracture lines were not observed and normal appearance was restored at 20 weeks. In case 2, the radiographs showed that fracture repair had progressed at 11 weeks. The fractures healed faster than expected in these two cases. The results indicate that rhBMP-2 and matrigel may be effective and useful materials to enhance healing of delayed fractures.

The objective of this study was to propose a rehabilitation protocol for distal radius fracture in Korean Medicine and to report its effectiveness. Three patients who had undergone distal radius fracture were treated using the rehabilitation protocol in Korean Medicine. We estimated the outcome evaluating physical examination findings of the wrist joint, numeric rating scale and quick the Disabilities of the Arm, Shoulder and Hand (DASH) score. After the treatment, we observed that wrist movement, numeric rating scale and quick DASH score were improved. A rehabilitation in Korean Medicine can be effectively used for distal radius fracture patients. The limitation of this study was the insufficient number of cases. Further studies are needed to design a rehabilitation protocol in Korean Medicine.

Objectives To report two patients with distal raidus fracture after a traffic accident improved by the complex of Korean medical admission treatment. Methods We collected data from April 2019 to October 2019. We surveyed the validity of the treatment with the range of motion (ROM), the European quality of life-5 dimension (EQ5D) and a numerical rating scale (NRS) at admission, two weeks, and discharge date of hospitalization. Results At the end of treatment, both patients had increased ROM, EQ5D and reduced NRS scores. Conclusions After the Korean medicine admission treatment, two patients showed to have been effective.

Spontaneous rupture of the extensor pollicis longus (EPL) tendon can occur in the 3rd extensor compartment after a distal radius fracture involving Lister's tubercle, steroid injections, or rheumatoid arthritis. We report a case of spontaneous rupture of the EPL tendon in a 26-year-old male patient who played a rhythm game, which requires repetitive wrist motions to play the drums. We also provide a comprehensive literature review along with the case report. From the authors' point of view, excessive and repetitive motion of the wrist, as shown in our case, can be a potential cause of spontaneous rupture of the EPL tendon.
