“…Because adhesion may decrease the gliding amplitude of the EDC tendon, it may reduce the active extension range of motion of the digits. A previous study found that metacarpal fractures frequently lead to extensor tendon dysfunction through adhesion 2 . Hence, extensor lag has been used in clinical applications to evaluate the extent of adhesions on the EDC tendon 2 .…”

“…A previous study found that metacarpal fractures frequently lead to extensor tendon dysfunction through adhesion 2 . Hence, extensor lag has been used in clinical applications to evaluate the extent of adhesions on the EDC tendon 2 . The extensor lag is defined as the difference between passive extension and full active extension when the passive extension of the finger exceeds the active motion 27 ; this was measured at the MCPJ and the interphalangeal joints (IPJ) using a goniometer (an instrument used for measuring the angles of human joints in clinics) to evaluate the functionality of the EDC tendon after rehabilitation.…”

“…These injuries often involve damage to multiple tissues because of the affected area being surrounded by soft tissues. Metacarpal fractures constitute 30% to 36% of all hand fractures 2 . Adhesion is a complication that may follow fractures and is defined as the formation of a pseudoinsertion at the tethered site on a tendon that obstructs the distal and proximal gliding of the tendon 3 .…”

“…The present study aims to test the hypothesis that the relative displacement between the extensor digitorum communis (EDC) tendon and its surrounding tissues can be used as an adhesion index (AI) for determining the extent of adhesion in patients with metacarpal fractures and identifying the locations of suspected adhesions. Emphasis is placed on verifying whether this index is correlated with extensor lag and single-digit-force, which are two clinical measures currently used for evaluating the gross extent of such adhesion 2 .…”

This study aims to determine if the relative displacement between the extensor digitorum communis (EDC) tendon and its surrounding tissues can be used as an adhesion index (AI) for assessing adhesion in metacarpal fractures by comparing two clinical measures, namely single-digit-force and extensor lag (i.e., the difference between passive extension and full active extension). The Fisher–Tippett block-matching method and a Kalman-filter algorithm were used to determine the relative displacements in 39 healthy subjects and 8 patients with metacarpal fractures. A goniometer was used to measure the extensor lag, and a force sensor was used to measure the single-digit-force. Measurements were obtained twice for each patient to evaluate the performance of the AI in assessing the progress of rehabilitation. The Pearson correlation coefficient was calculated to quantify the various correlations between the AI, extensor lag, and single-digit-force. The results showed strong correlations between the AI and the extensor lag, the AI and the single-digit-force, and the extensor lag and the single-digit-force (r = 0.718, −0.849, and −0.741; P = 0.002, P < 0.001, and P = 0.001, respectively). The AI in the patients gradually decreased after continuous rehabilitation, but remained higher than that of healthy participants.
