Simultaneous fractures of the distal radius and scaphoid are uncommon. The reported frequency has varied from 0.7% to 6.5% in cases of isolated fractures of each bone [1–3]. Techniques currently in use for fixation of the distal radius include casting, pin-in-cast, and external fixation with or without pinning, while those used for fixation of the scaphoid include thumb spica cast, percutaneous pinning to open reduction, and screw fixation [2–6]. Some authors have suggested that cast or splint immobilization is adequate for scaphoid fractures [3, 5], while others have suggested that fixation of the scaphoid before reduction of the distal radius is needed to prevent distraction of the scaphoid, which may induce nonunion [4, 6]. The purpose of this study was to review the results in patients with ipsilateral fractures of the distal radius and scaphoid treated at National Taiwan University Hospital from 1987 through 1998. Abstract: Simultaneous fractures of the distal radius and scaphoid are uncommon. Previous reports have outlined a variety of treatment methods for this condition. We describe the results in eight patients with simultaneous fractures of the distal radius and scaphoid, who were treated at National Taiwan University Hospital from 1987 to 1998. Treatments for the distal radius fractures included pin-in-cast in one patient, casting in one, external fixation in one, external fixation after pinning in three, and open reduction with internal fixation in two. All scaphoid fractures occurred at the scaphoid waist, and were treated with long-arm thumb spica in three patients, Herbert screw fixation in two, and percutaneous pinning in three. All of the fractures united, and none of the patients developed scaphoid avascular necrosis. One patient suffered from superficial radial nerve injury during external fixation. The functional results of the wrist were good in five patients and fair in three. To prevent the possible over-distraction of the scaphoid fracture, fixation of the scaphoid should be performed if a distraction force is to be applied during the treatment of the distal radius fracture. If no distraction force is to be applied, a thumb spica may provide adequate fixation for the scaphoid fracture.

Scaphoid Fractures: A Comparison of Two Surgical Methods for Internal Fixation Using Either Herbert Screws or Multiple Pins
Background and Aims: Scaphoid fractures are the most common fractures of the wrist. This study compared the outcomes of two surgical internal fixation techniques, using either Herbert screws (HS group) or multiple pins (MP group), in the treatment of scaphoid fractures. Methods: This cross-sectional study was performed on 41 patients (23 in HS and 18 in MP groups) with unilateral scaphoid fract...

RS Richards, JH Roth. Scaphoid fractures. Can J Plast Surg 1996;4(3):143-149. Scaphoid fractures are the most common carpal bone fractures and present physicians with many problems. The majority of such fractures (90%) will unite if properly treated; however a scaphoid fracture that goes on to nonunion affects a patient’s working capacity for a long period of time. This paper reviews the pathop...
متن کاملCurrent methods of diagnosis and treatment of scaphoid fractures
Fractures of the scaphoid bone mainly occur in young adults and constitute 2-7% of all fractures. The specific blood supply in combination with the demanding functional requirements can easily lead to disturbed fracture healing. Displaced scaphoid fractures are seen on radiographs. The diagnostic strategy of suspected scaphoid fractures, however, is surrounded by controversy. Bone scintigraphy,...
متن کاملTreatment of scaphoid fractures and nonunions.
Scaphoid fractures are common but present unique challenges because of the particular geometry of the fractures and the tenuous vascular pattern of the scaphoid. Delays in diagnosis and inadequate treatment for acute scaphoid fractures can lead to nonunions and subsequent degenerative wrist arthritis. Improvements in diagnosis, surgical treatment, and implant materials have encouraged a trend t...

متن کاملOperative management of nonunion scaphoid fracture in children: a case report and literature review.
Scaphoid fractures are uncommon in children, but if maltreated, they can result in nonunion. The authors report a case of left scaphoid nonunion in an 11-year-old boy. The operative management of this pseudarthrosis was performed (K-wire fixation and bone grafting of scaphoid). After a 10-month follow-up period, the left wrist regained a full range of motion with no impairment. The roentgenogra...
