Introduction:
Flexor tendon lacerations in zone II have been reported to be the most complicated of all tendon injuries. Currently, there is no consensus on treatment in surgical management for patients with flexor tendon laceration of flexor digitorum profundus and flexor digitorum superficialis (FDS). The aim of this study was to evaluate whether the repair of FDS tendons provided superior functional outcomes compared with FDS excision in Hispanic patients.
Methods:
Total active motion, original Strickland criteria, and the disability of arm shoulder and hand questionnaire were provided postoperatively at 3 and 6 months to all consecutive Hispanic patients who underwent zone II flexor tendon repair. The cohort was divided into two groups, those who underwent FDS repair and those underwent FDS excision.
Results:
Functional and disability outcome analysis showed a notable improvement with FDS repair using total active motion, Strickland criteria, and disability of arm shoulder and hand score at the 3 months postoperative interval. No statistical differences were identified regarding functional and disability outcomes at the 6-month evaluation between both groups.
Conclusions:
Among Hispanics, the FDS-repaired group had similar functional and disability outcomes at their 6 months postoperative evaluation compared with the FDS-excised group. Increased awareness for tendon rerupture during the initial 3 months of index surgery is recommended for FDS-excised patients.
