Infected Epidermoid Cyst Including Multiple Nails at the Amputated Thumb Stump: A Case Report

Fingertip amputation is a common injury among trauma occurring in the upper extremity. After amputation of the fingertip, there are several treatment options according to the degree of damage. Also, the skin flap is sometimes performed when skin defects are accompanied. Among the complications associated with fingertip injury, cyst formation at the amputation stump is rare but some cases have been reported based on the pathologic findings. There was a case of an infected epidermal inclusion cyst containing multiple nail plates at the amputation stump of the thumb, so we would like to report it with a review of the literature.

Replantation fingertip without venous anastomoses in children

Objective. Traumatic complete and partial finger amputations are rare in comparison with adults. There are significant differences between mechanism of trauma, principles of treatment children with this type of injury in comparison with adults.Clinical case. A 15-years old child suffered from injury by axe, which caused the traumatic fingertip amputation of III and IV digits of his right hand. Replantation of both amputated parts was performed. Arteries and nerves were repaired with no veins anastomosed. As a result - survival of replanted parts.Discussion. A submillimeter diameter of vessels and potential venous congestion are basic problems that a surgeon deal with when perform the replantation of fingertips. Respectively, a difficulty in post-operative care of patient appears.Conclusion. Replantation of amputated part of finger is a golden standard of treatment of children with a described type of injury. The correct deliverance of amputated parts, the shortest time of ischemia as possible, a qualitive operation and post-operative care play an important role in successful survival of the replanted segments.

Artery-Only Fingertip Replantation Distal to the Lunula: A Retrospective Analysis of Clinical Results

Background: Both arterial and venous repair are crucial for optimal results in digital replantation. However, anastomosis of veins becomes challenging in very distal fingertip amputation. This study aimed to report the clinical results of an artery-only replantation without vein repair for a distal fingertip amputation and to analyze the survival rate and clinical outcomes based on the amputation level. Methods: We performed a retrospective review of 47 digits in 38 patients who had undergone fingertip replantation with a mean follow-up period of 12 months. All patients had complete fingertip amputation distal to the lunula. Only one central artery repair distal to the arch was performed. All patients received the postoperative protocol including external bleeding and anticoagulation therapy. Results: By Ishilawa’s classification, 12 digits in subzone I, and 35 digits in subzone II. 31 of the 47 fingertip replantations (66%) were successful, and a significantly higher survival rate was observed in subzone I than in subzone II. The mean total active motion of surviving digits was 86% of normal side. The mean grip strength was 82% of normal side. The sensory recovery according to modified Highet and Saunders’ classification was S4, S3+, S3, and S2 in fingers 19, 2, 5 and 3, respectively. Conclusions: 66% of survival rate was achieved in fingertip replantation distal to lunula which including large number of crushing/avulsion injury. The result of comparison for the survival rate based on amputation level, a significantly higher survival rate was observed in subzone I compared to subzone II. Therefore, the artery-only fingertip replantation had a better indication for distal amputation, and an aggressive attempt for venous anastomosis or drainage, including a secondary surgery for proximal amputation could be attributed to a higher success rate.

Simultaneous Volar Pulp and Nail Bed Reconstruction with the Second Toe Onychocutaneous Free Flap

Fingertip injury is one of the most common hand injuries. Although several types of advancement and cross-finger flaps exist, they would not be essential for nail bed defects. The authors present a simultaneous volar pulp and nail bed reconstructive technique that uses a second toe onychocutaneous free flap. Four patients without amputees underwent fingertip amputation reconstruction between 2011 and 2019. After thorough debridement, the defect size was estimated, and the digital arteries, nerves, and veins of the recipient were evaluated. The flap, composed of pulp tissue and nail bed, was harvested with continuity from the second toe. Additional split-thickness skin grafts were performed in two cases. All flaps survived without considerable complications. We evaluated the scar and contour, and nail growth was reported over Zook’s criteria grade B. The second toe onychocutaneous free flap provides a reliable option for fingertip defects that involve pulp tissue and nail bed without further amputation.

Newly Formed Nail from the Remnant Germinal Matrix after Reconstruction of the Amputated Fingertip: A Review of Two Cases

Meticulous debridement before reconstructive surgery for fingertip amputation, one of the most common hand injuries, is often crucial for better prognoses. Complete debridement to prevent abnormal formation of the nail plate will result in better quality of life for patients with a small remnant germinal matrix. The author will report two cases where nail plates formed abnormally after reconstruction of an amputated fingertip.
