Treatment of complex interphalangeal joint fractures with dynamic external traction: a series of 20 cases.
Data are reported for a series of 20 patients who were treated with the pins and rubbers traction system for fractures of the proximal interphalangeal joints of the long fingers. This technique allows fracture reduction with external dynamic traction and immediate active mobilization. ⋯ For two others, the pins and rubbers traction system needed to be removed early (during the first week) because of intolerance or infection. Sixteen patients who were reexamined after minimal follow-up periods of 1 year demonstrated a mean active range of motion of 85.9 degrees for the injured joint; only one patient experienced intermittent pain.

TIMP-1, MMP-2, MMP-9, and PIIINP as serum markers for skin fibrosis in patients following severe burn trauma.
The wound-healing process of patients with severe burns often leads to the formation of extensive fibrotic scars. In this study, serum concentrations of tissue inhibitors of metalloproteinase-1 (TIMP-1), matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9), and amino-terminal propeptide of procollagen type III (PIIINP) were measured by enzyme-linked immunosorbent assay as markers for excessive cicatrization in 22 patients with acute burn injuries. All patients were followed up for 6 months to determine a fibrotic reaction during the wound-healing process after operative treatment using the Burn Scar Index. ⋯ Obviously, the physiological balance between matrix metalloproteinases and their endogenous inhibitors is disturbed after burn trauma. The elevated systemic TIMP-1 concentration might contribute to tissue fibrosis, leading to pathological scar formation. The increase of PIIINP after thermal trauma indicates a fibrogenic component of wound healing.
