BACKGROUND It is not clear whether the pronator quadratus (PQ) muscle actually heals and provides a meaningful pronation force after volar plating for distal radius fractures (DRFs). We aimed to determine whether the length of the PQ muscle, which is dissected and then repaired during volar plating for a DRF, affects the forearm rotation strength and clinical outcomes. METHODS We examined 41 ...

Volar fixed-angle fixation of distal radius fractures is a new method of treatment that provides the benefits of stable internal fixation without incurring the disadvantages of the dorsal approach. The DVR plate is a new fixation implant that was introduced specifically for the purpose of managing both dorsal and volar displaced fractures from the volar aspect. Experience gained applying volar ...

A total of 118 consecutive patients with a fracture of the distal radius were treated with a volar locking plate; 50 patients had no ulnar styloid fracture, 41 had a basal ulnar styloid fracture, and 27 had a fracture of the tip of the ulnar styloid. There were no significant differences in radiological and clinical results among the three groups. The outcome was good and was independent of the...

Blazar, M.D. Assistant Professor in Orthopedic Surgery Harvard Medical School Attending Physician, Department of Orthopaedic Surgery Brigham and Women’s Hospital 75 Francis Street Boston, MA 02115 (617) 732-8550 [email protected] INTRODUCTION Metacarpophalangeal (MP) arthroplasty is the most common and successful joint replacement surgery of the hand. This paper will briefly review...

Two unusual cases of isolated closed complex dislocation of the metacarpophalangeal joint of the third finger are presented. The single most important element preventing reduction was interposition of the volar plate between the proximal end of the phalanx and the head of the metacarpal, but the deep transverse ligament was also intimately involved in the entrapment mechanism. Such dislocations...

Distal radius fractures in young adults are associated with high-energy trauma and elderly people low-energy falls. One of the distal is Barton Fracture (BF), a radiocarpal fracture-luxation whose production mechanism usually varies, most common being fall on an extended pronated wrist. We present 27-year-old male patient epiphysis injury dislocation following blunt trauma. Timely osteosynthesi...

BACKGROUND Volar Barton's fractures are not uncommon but more convincing treatment methods are still controversial. Currently, open reduction with buttress plating or closed reduction with external fixation and percutaneous Kirschner wire fixation have achieved most support. METHODS Twenty-three consecutive volar Barton's fractures treated with either open reduction and buttress plate fixatio...

Triggering of finger joints due to tendon lesions is a well known entity, but locking of the metacarpo-phalangeal joint due to a derangement of the joint or its capsule is uncommon. In 1949 Langenskiold reported two cases in which the collateral ligaments were catching on the metacarpal head and causing the locking; he noted that this possibility had been mentioned by Poirier in 1889. The same ...
