Synovectomy of the radiocarpal and midcarpal
joints is very successful at relieving pain, however this is usually at the cost of loss of motion of the wrist and it does not prevent further deterioration of the cartilage and bony architecture of the wrist.
Subluxation can occur at the midcarpal
joint or at the radiocarpal joint.
Carpal bone mobilization practice includes dorsal-palmar glide at the radiocarpal joint and midcarpal
(and radiocarpal) distraction.
For this reason, communication between the radiocarpal and midcarpal
compartments during fluoroscopic or MR arthrograms does not necessarily represent a symptomatic finding or reflect a traumatic tear of the ligament.
The examination site was 8 cm and set to encompass radioulnar, radiocarpal, midcarpal
, and proximal metacarpal heads.
Radiographically, the SL gap should be closed and the midcarpal
joint should appear anatomic.
Chapters focusing on the wrist section address setup, anatomy, portal, and diagnostic basics; basic procedures, including excision of dorsal ganglion; advanced procedures for midcarpal
instability, acute scaphoid fractures in nonunions, and carpal, metacarpal, and phalangeal fractures; carpal tunnel release; and complications.
Isometric exercise of the FCU will act to compress the pisiform against the volar aspect of the triquetrum, thus contributing to stability in the presence of an ulnar midcarpal
They are classified as scapholunate dissociation, perilunate dislocation, midcarpal
dislocation and lunate dislocation.
Complete tears demonstrate communication between the radiocarpal and the midcarpal
joints and will allow contrast to extend into the midcarpal
joint after a single compartment radiocarpal injection (Figure 13).
Type II carpal instability is a midcarpal
dorsal intercalated segment instability, which is a "fixed" deformity.
This study will determine which of the following angular measurements--scapholunate, radiolunate, capitolunate angles, or the triangulation method--has the best intraobserver reproducibility and interobserver reliability in assessing midcarpal
