Selected Outcomes of Thumb Replantation After Isolated Thumb Amputation Injury
The Journal of Hand Surgery, 2010
The aim of this study was to assess thumb survival, pinch strength, grip strength, and need for secondary surgery in patients undergoing thumb replantation after isolated thumb amputation injury. Methods We conducted a retrospective review of 52 consecutive isolated thumb replantations performed over a 4.5-year period. Charts were reviewed for mechanism of injury, level of amputation, and surgical technique. Primary outcomes of interest included survival and secondary surgery (eg, tenolysis, neurolysis) rates. Functional outcome was assessed by pinch and grip strengths after a mean follow-up period of 10 months from the initial injury. Results The overall thumb survival rate was 92% (48 of 52). One hundred percent of Zone I injuries (13 of 13), 94% of zone II injuries (29 of 31), and 75% of zone III injuries (6 of 8) survived; overall survival was 94% in sharp injuries (32 of 34), 89% in avulsion injuries (8 of 9), and 89% in crush injuries (8 of 9). Secondary surgery was performed in 18 patients with increasing need across the 3 zones (0%, 42%, and 63%, respectively; p for trend ϭ .002). Pinch and grip strengths of 17 patients after an average follow-up period of 10 months were significantly worse after crush/avulsion injuries (p ϭ .007 and .07, respectively) and injuries requiring joint intervention (p ϭ .004 and .02, respectively); grip strength was also found to be negatively associated with increasing zone of injury. Conclusions This retrospective study shows that a high rate of survival can be achieved after thumb replantation using current techniques. In addition, the need for secondary surgery is strongly related to zone of injury, with zone I injuries requiring the least amount of secondary surgery. Finally, pinch and grip strengths may be worse after crush or avulsion injuries and injuries requiring joint intervention.

Eight cases that had a reconstructive thumb operation (RTO) and were able to return to work were presented. In the present study, the functions of RT, the influence of the thumb on return to work, and how the recovered hands were used at work were investigated. The reconstructed thumb was evaluated based on the following 6 functions: "aspects of full return to work" (3 items), "thumb motion" (5 items), "sensibility" (3 items), "wrist range of motion (ROM)" (4 items), "strength" (3 items) and "dexterity" (3 items). Subsequently, the relation between the frequency of hand use based on subjective evaluation and each function was investigated. We observed significant correlations of the frequency of hand use with thumb opposition, thumb angle, pinch strength, 2-point discrimination (2PD), and the result of the Moberg picking up test (p<0.05). It was thought that the improvement of pinch strength and dexterity of the thumb as well as that of sensory function was the factor to increase the frequency of hand use based on subjective evaluation, and the active hand therapy was necessary even before the operation.
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.
Functional outcome of patients undergoing replantation of hand at wrist level-7 year experience
Indian Journal of Plastic Surgery, 2013
Background: Replantation is defined as reattachment of amputated limb using neurovascular and musculoskeletal structures in order to obtain recovery of limb. Re-vascularisation involves all the above steps in case of limb injuries that result in a near total amputation. Aim and Objective: To study the functional outcome of patients undergoing replantation of hand at wrist level. Material and Methods: This is a retrospective study of patients who underwent replantation of total amputation of hand at wrist level within a period of Jan 2003-June 2010. We evaluated post operative functional outcome compared to uninjured hand taking into consideration: 1. The patient′s overall satisfaction with the hand. 2. Recovery of flexor and extensor function of thumb and fingers. 3. Recovery of thumb opposition. 4. Recovery of sensations in the median and ulnar nerve distribution. 5. Ability of surviving hand to perform daily tasks. Results: There were total seventeen patients and age range was two...
Primary use of the index finger for reconstruction of amputated thumbs
British Journal of Plastic Surgery, 2004
Seven cases of primary reconstruction of traumatic amputation of the thumb using the index finger are reported. In six cases, the reconstruction was done using an injured index finger, while in one case where the amputation of the thumb was through the carpometacarpal joint, an intact index finger was primarily pollicised. This reduces cost of treatment, hospitalisation period and allows earlier rehabilitation without a period of a 'no thumb experience'. We have followed all the patients for a minimum period of 2 years and all of them have excellent functional results. We believe that pollicisation of a normal index finger, if thumb amputation is through the carpometacarpal joint or an injured index finger at the time of initial management of a severely traumatised hand with thumb amputation is an excellent technique for thumb reconstruction.
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.
Rehabilitation after successful finger replantations
İstanbul Kuzey Klinikleri, 2016
OBJECTIVE: The aim of the present study was to assess results of rehabilitation of patients after finger replantation. METHODS: The study examined 160 fingers amputated and replanted at various levels between 2000 and 2013 at the clinic. Mean patient age was 29.4 years. Mean follow-up time was 23 months. Rehabilitation of fingers began between postoperative fourth and eighth week and continued until the 24th week. Range of motion of affected hand, return to daily activities, aesthetic appearance, and patient satisfaction were assessed according to Tamai criteria. RESULTS: Functional results according to Tamai criteria were perfect in 36 patients, good in 54 patients, average in 27 patients, and poor in 18 patients. CONCLUSION: Post-operative rehabilitation of replanted fingers should begin as soon as possible. During the rehabilitation period, physiotherapist, surgeon, and patient must work in close cooperation. Functional results of patients who adjust to the rehabilitation program, home practice, and splint usage are better.

To compare the functional outcome of successful microsurgical replantation versus amputation closure for single fingertip amputations. Methods: Forty-six fingertip amputations in 46 patients (23 were replanted successfully, 23 had amputation closure) were included in this study. Thumb amputations were excluded. Grip strength and active range of motion of the proximal interphalangeal joint were evaluated. The patients were questioned about their symptoms of pain, paresthesia, and cold intolerance. The Disabilities of the Arm, Shoulder, and Hand questionnaire was given and the disability/symptom score was evaluated. Patients' satisfaction with the surgical result was assessed. Time spent in the hospital and time off from work were reviewed. Results: Active range of motion of the proximal interphalangeal joint was greater in the successful replantation group. Although the existence of paresthesia and cold intolerance were not statistically different between the 2 groups, pain in the affected fingers was more frequent in the amputation closure group. The average Disabilities of the Arm, Shoulder, and Hand score of the successful replantation group was statistically better. All patients in the successful replantation group were highly or fairly satisfied with the surgical results, whereas 14 patients in the amputation closure group were highly or fairly satisfied. The time spent in the hospital and the time off from work for the successful replantation group were longer. Conclusions: Successful replantation of single fingertip amputations can result in minimal pain, better functional outcome, better appearance, and higher patient satisfaction. We recommend attempting fingertip replantation not only to obtain the best appearance but also to gain better functional outcome. If the patient requests the simple surgery and earlier return to work amputation closure is an accepted method despite the disadvantage of digital shortening and the risk for a painful stump.
