Replantation of Completely Amputated Thumbs With Venous Arterialization
The Journal of Hand Surgery, 2007
To report a new method of replanting completely amputated thumbs with venous arterialization. In 6 replantation surgeries of completely amputated thumbs performed during the period 1999-2003, the proximal artery was anastomosed with a vein of the amputated part to establish inflow and the proximal vein was anastomosed with several other veins in the amputated part to establish outflow. This was because the proper palmar digital arteries were seriously injured or anastomosis of proper palmar digital arteries failed many times. All the replanted thumbs survived, regained good sensory and motor functions, and showed no difference from thumbs replanted conventionally. Venous arterialization may salvage otherwise unreplantable thumbs.
Successful Replantation of an Amputated Thumb : A Case Report
Orthopedics and Rheumatology Open Access Journal, 2017
The best indication of replantation is first of all, the amputated thumb, among all fingers, since the thumb is functionally the most important digit. Therefore, replantation of the thumb should be attempted even under unfavorable conditions. We report a replantation surgery in a young male patient with an amputation of the thumb between the base of proximal phalanx and the interphalangeal joint.
Replantation by palmar arteriovenous anastomosis in complex finger amputations
Chirurgie de la Main, 2015
Digital replantation is a well-established and increasingly common procedure in specialized hand surgery units worldwide. Replantation after complex trauma is often challenging due to severely injured, small-diameter vessels, especially at the distal level. Digit salvage by arteriovenous anastomosis has been inadequately described in the literature for such cases. The objective of this study was to evaluate the outcomes and complications of arteriovenous digital replantation in complex amputations. We reviewed five cases of digital replantation using a single palmar afferent arteriovenous anastomosis and drainage via a dorsal vein. The postoperative protocol followed our standard replantation protocol. All digits survived with no revision procedures. No major complications were observed. One digit developed partial epidermolysis and one thumb developed marginal skin necrosis, both treated conservatively. The color of the replanted digits was not a reliable monitoring parameter but capillary refill was consistently visible. Microangiography performed four months after surgery demonstrated good digit perfusion. Our results support palmar arteriovenous anastomosis as a reliable alternative in digital replantation if distal arteries are unavailable for anastomosis. The results also suggest that this digit salvage procedure can be carried out at a more proximal level than previously reported.
Late results of replantations in tip amputations of the thumb
Acta Orthopaedica et Traumatologica Turcica, 2008
Amaç: Başparmak Tamai tip 1 amputasyonlarda uygulanan replantasyonlar geriye dönük olarak değerlendirildi. Çalışma planı: Çalışmaya, başparmak tırnak yatağı distalinde meydana gelen Tamai tip 1 amputasyonlar nedeniyle replantasyon uygulanan ve tedavi sonrasında dolaşım devamı sağlanan 14 hasta (12 erkek, 2 kadın; ort. yaş 28; dağılım 14-40) alındı. Tüm hastalarda santral digital arter anastomozu yapıldı. Anastomoza uygun ven bulunabilen dört hastada birer adet volar ven anastomozu yapıldı. Sinir tamiri sadece üç hastada yapılabildi. Duyu değerlendirmesi Semmes-Weinstein testi, iki nokta ayrım testi, hareketli iki nokta ayrım testi ve vibrasyon testi ile yapıldı; ayrıca, hastalar parmak atrofisi, soğuk intoleransı ve tırnak yatağı deformiteleri açısından incelendi. Ortalama takip süresi 11 ay (dağılım 6-48) idi. Sonuçlar: Semmes-Weinstein testi beş parmakta (%35.7) yeşil (dağılım 2.83-3.22), sekiz parmakta (%57.1) mavi (dağılım 3.22-3.61), bir parmakta (%7.1) mor (dağılım 3.84-4.31) idi. İki nokta ayrım testi ortalama skoru 6.9 mm (dağılım 3-11 mm), hareketli iki nokta ayrım testi ortalama skoru 4.5 mm (dağılım 3-6 mm) bulundu. Aynı elin sağlıklı parmaklarıyla karşılaştırıldığında, vibrasyon altı başparmakta (%42.9) artmış, altı başparmakta azalmış bulunurken, iki başparmağın (%14.3) vibrasyonu diğer parmaklarla eşit idi. Beş parmağın (%35.7) replante edilen kısmında atrofi; üçer hastada (%21.4) ise soğuk intoleransı ve tırnak deformitesi görüldü. Hastaların işe dönüş süreleri ortalaması 3.2 aydı (dağılım 2-6 ay). Çıkarımlar: Başparmak distal uç replantasyonları, teknik zorluklara rağmen, görünüm açısından ve fonksiyonel açıdan iyi sonuçlar vermektedir. Sinir tamiri yapılamayan olgularda da yeterli duysal iyileşme sağlanmaktadır.
Standardized Protocol for Artery-Only Fingertip Replantation
The Journal of Hand Surgery, 2010
Purpose Artery-only fingertip replantation can be reliable if low-resistance flow through the replant is maintained until venous outflow is restored naturally. Injuring the tip of the replant to promote ongoing bleeding augmented with anticoagulation usually accomplishes this; however, such management results in prolonged hospitalization. In this study, we analyzed the outcomes of artery-only fingertip replantation using a standardized postoperative protocol consisting of dextran-40, heparin, and leech therapy. Methods Between 2001 and 2008, we performed 19 artery-only fingertip replants for 17 patients. All patients had the replanted nail plate removed and received intravenous dextran-40, heparin, and aspirin to promote fingertip bleeding and vascular outflow. Anticoagulation was titrated to promote a controlled bleed until physiologic venous outflow was restored by neovascularization. We used medicinal leeches and mechanical heparin scrubbing for acute decongestion. By postoperative day 6, bleeding was no longer promoted. We initiated fluorescent dye perfusion studies to assess circulatory competence and direct further anticoagulant intervention if necessary. The absence of bleeding associated with an initial rise followed by an appropriate fall in fluorescent dye concentration would trigger a weaning of anticoagulation. Results All of the 19 replants survived. The average length of hospital stay was 9 days (range, 7-17 d). Eleven patients received blood transfusions. The average transfusion was 1.8 units (range, 0-9 units). All patients were happy with the decision to replant, and the cosmetic result. Conclusions A protocol that promotes temporary, controlled bleeding from the fingertip is protective of artery-only replants distal to the distal interphalangeal joint until physiologic venous outflow is restored. The protocol described is both safe and reliable. The patient should be informed that such replant attempts may result in the need for transfusions and extended hospital stays, factors that can help the physician and patient decide whether to proceed with repantation.
Index finger salvage with replantation and revascularization: Revisiting conventional wisdom
Microsurgery, 2008
Replantation/revascularization of severely injured single digits is controversial, especially at the index position. Conventional wisdom is that these digits if salvaged will ultimately worsen residual hand function and they should be amputated. Twenty‐eight cases of such index salvages were reviewed to test this hypothesis. Five cases involved children and were excluded. Twenty‐three replants/revascularizations survived (100%). Total active motion was 170° in zone 1, and 133° for zone 2 injuries. Patient satisfaction was high in all cases. In selected cases, salvage of severely injured and amputated index fingers has the potential for satisfying survival and functional results and dogmatic treatment with completion amputation should be avoided. © 2008 Wiley‐Liss, Inc.

An amputation of the hand is a devastating injury. It adversely affects the victim's ability to earn a livelihood, support a family, and carry out daily activities. It has a great psychological impact. We report a middle aged male with an amputation at the level of the distal forearm who underwent replantation. The operative details of this case are described. Awareness of the possibility of salvage should be spread among healthcare personnel and the need for immediate attention by a multispeciality team is advocated. This report reviews the literature related to the operative technique, contraindications and long term results.
A COMPARISON OF REPLANTATION AND TERMINALIZATION AFTER DISTAL FINGER AMPUTATION
This study records the subjective opinion of 30 patients who sustained a distal amputation of a single finger beyond the FDS tendon insertion which was treated by replantation, successfully or unsuccessfully, or by terminalization. All other patients who underwent replantation or terminalization of a single distal finger amputation but also had other injuries of the hand or fingers were excluded. Eleven patients had successful replantation, nine in whom replantation was not possible or was not successfnl had subsequent terminalization and ten had primary terminalization without attempting replantation. Only seven of the patients undergoing terminalization had further shortening of bone, the remainder being treated with homodigital neurovascular advancement flaps. Replantation was favoured by patients for sensory and motor functional reasons as well as for cosmetic reasons. Cold intolerance was less common in the successfully replanted fingers.
