Patterns of Peripheral Nerve and Tendon Injury in Hand Trauma Patients in a Tertiary Care Hospital of Pakistan.

Introduction Traumatic injury to peripheral nerves is a major medical problem worldwide. Moreover, injury to the hand and wrist can lead to extreme morbidity and disable the injured for life. In this study, we highlight the most commonly damaged nerves and tendons that get ruptured in different types of hand trauma patients. No recent study has been done to document the etiologies and quantify the patterns of nerve and tendon involvement in hand injuries to the best of our knowledge. Methodology This was a cross-sectional study conducted at the largest trauma center in the city and the Plastic and Reconstructive Surgery ward of Civil Hospital, Karachi. A convenient sampling of 200 patients was done with the help of a preformed, well-structured questionnaire. Patients whose hand was injured solely were included in the study and those with the involvement of the whole limb or other parts of the body were excluded. Results We found that most males between the ages of 11 and 20 years presented predominantly with right-hand injury while working with machines. Nerve injury proved to be a rare occurrence. However, combined nerve injury of the ulnar, median, and radial nerve was seen in poly digit trauma. The median nerve was the most commonly damaged nerve in poly digit trauma. Among the tendon injuries, the incidence of combined tendon injury was the greatest. The flexor digitorum superficialis was the most common tendon injured overall. Conclusion This study significantly states that tendons are frequently injured in hand accidents. Plastic surgeons must also be aware of optimal nerve repair and reconstruction techniques to limit the physical disabilities and economic burden arising from nerve injury of the dominant hand.
