ABSTRACT
Introduction and Importance: Sagittal band (SB) injuries, often termed Boxer's Knuckle, are a significant cause of extensor tendon instability at the metacarpophalangeal (MCP) joint. These injuries are typically the result of trauma, leading to pain, swelling, and difficulty in finger extension. The radial sagittal band is more susceptible to rupture due to its thinner structure and greater exposure to radially directed forces. This report presents a case of a chronic SB injury following a boxing match, managed surgically.
Case Presentation: A 37-year-old male presented with a two-month history of a catching sensation and deformity in his third finger, following a boxing injury. He also experienced tingling in the left hand's ring and little fingers. Examination revealed an angulation deformity and limited range of motion in the hand and wrist. Previous imaging suggested a neglected fracture and dislocation. The patient underwent open direct repair of the extensor hood using a tendon graft, under regional anesthesia. Postoperative care included immobilization followed by dynamic splinting.
Clinical Discussion: SB injuries range from mild tenderness to complete tendon dislocation. In this case, the severity and chronicity required surgical intervention. The use of a tendon graft was necessary to restore stability and function. Postoperative management focused on preventing recurrence and restoring mobility
Conclusion: This case highlights the need for timely diagnosis and tailored surgical treatment in SB injuries. Early intervention and structured rehabilitation are crucial for optimal recovery, particularly in athletes, to prevent long-term functional deficits
