Primary Outcome Measures:
  • Range of motion; Arm, Shoulder and Hand questionnaire [ Time Frame: 4 years ]
    The active motions of the hand were measured by a goniometer. The patients rated their MCP joint pain, the donor joint pain, and scar pain using a line by a visual analogue scale (VAS). We used the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire to assess the hand function.


Secondary Outcome Measures:
  • Pain [ Time Frame: 4 years ]
    joint pain is assessed using visual analogue scale


Enrollment: 15
Study Start Date: January 2005
Study Completion Date: December 2009
Primary Completion Date: January 2005 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: MCP joint
reconstruction of metacarpophalangeal (MCP) joint
Procedure: MCP joint
reconstruction of metacarpophalangeal (MCP) joint using a bone graft
Other Name: MCP joint reconstruction

Detailed Description:
The metacarpophalangeal joint is vital for hand function. Cartilage loss of the joint is central to the development of joint failure in arthritis. Although various treatments have been proposed, the management remains a challenging problem.Previous anatomical studies have shown that, at the base of the metacarpal, there were nutrient arteries inserting into the dorsum of the metacarpal. The nutrient arteries arise from the distal and middle dorsal carpal arches that run distally to the first to fourth dorsal metacarpal arteries (DMAs. These studies prompt us to use a reverse vascularized cartilage and bone graft based on the DMA. The metacarpal consists of a widened proximal base. The joint surface to the capitate is convex anteriorly and dorsally concave, where it extends to the styloid process on the dorsolateral aspect of the metacarpal base. The unique contour stimulates our imagination and creativity to use a portion of the joint surface for reconstruction of metacarpophalangeal joint defects. The purpose of this study is to report the novel technique and to evaluate the effectiveness of the treatment.
