Use of the technique for extensor tendon acceleration with an injured soldier after a metacarpal fracture

Abstract

Objective The purpose of this case report was to evaluate the effectiveness of the ‘technique for extensor tendon acceleration’ (TETA) in improving an active extensor lag at the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints after a surgically repaired, stable metacarpal fracture (MCF). The TETA was used in combination with scar mobilization, exercise and splinting with an injured soldier who sustained an MCF while on active duty. Methods This case report is about a soldier injured during the Iraq War who used the TETA, in combination with other treatments, as a means for resolving an extensor lag in a stable fourth digit MCF. The pre- and post-TETA outcome measure was range of motion (ROM). The ROM was taken before initiation of the TETA and two weeks after its initiation. Results After two weeks of performing the TETA in combination with other treatments, the soldier demonstrated a measurable improvement in the extensor lags at both the MCP and PIP joints. The soldier's fourth digit total active motion improved by 55° while the MCP joint extensor lag improved by 10° and the PIP joint extensor lag improved by 20°. Conclusion This case report demonstrated a potential benefit for using the TETA in conjunction with other treatments in overcoming an active extensor lag after a stable MCF. These results are case specific and may not be generalized to a larger population until future research studies can be conducted.
