ABSTRACT
Objective:To explore the effects of lateral finger flap and micro free venous flap on the replantation repair of skin defect type severed fingers and their impact on finger function recovery.Methods:A retrospective selection was conducted on the clinical data of 94 patients (94 fingers) with skin defect type finger amputation admitted to Affiliated Hospital of Jiangnan University from January 2020 to September 2022. According to the different design methods of the skin flap, there were 48 cases in the observation group (micro free venous flap) and 46 cases in the control group (finger side flap). We compared the repair effects, blood circulation, finger function recovery, and complications between two groups.Results:Two months after surgery, there was no statistically significant difference ( P>0.05) in the total effective rate of repair between the observation group [79.17%(38/48)] and the control group [76.09%(35/46)]. The blood flow velocity, skin temperature, and skin redness ratio of the observation group were higher than those of the control group, and the capillary filling time was shorter than that of the control group, with statistical significance (all P<0.05). There was no statistically significant difference (all P>0.05) in the scores of joint autonomy, daily living activities, and recovery between the two groups. The subjective sensation and appearance scores of the observation group were lower than those of the control group, and the differences were statistically significant (all P<0.05). The incidence of complications in the observation group was 10.42%(5/48), and there was no statistically significant difference ( P>0.05) compared to the incidence of complications in the control group [13.04%(6/46)]. Conclusions:For patients with severed fingers with skin defects, the lateral finger flap and mini free vein flap are effective methods for replantation. In clinical practice, reasonable skin flap repair methods can be flexibly selected based on the patient′s actual situation.
ABSTRACT
Objective:To explore the application value of free nail flaps in reconstruction of nail bed and fingertip defect.Methods:From January 2018 to June 2020, nine patients with free nail flap transplantation to treat fingertip injuries in Lishui People′s Hospital were included in this study. According to the Allen classification, 6 patients were characterized as type Ⅱ and 3 were characterized as type Ⅲ. Evaluation was based on the patients′ medical records and follow-up, including postoperative healing of recipient and donor sites, two-point discrimination, the Chinese Medical Association Hand Surgery Society′s evaluation of the function of severed finger replantation, and Michigan Hand Outcomes Questionnaire (MHQ) and Foot Function Index (FFI).Results:All patients successfully completed the operation, the operation time was 3.0-5.0 h (average 4.1 h), the intraoperative blood loss was 100-250 ml (average 178 ml), and the follow-up time was 12-40 months (average 25 months). The nails and flaps of all patients survived with primary healing. No complications were observed after surgery. The appearance of the reconstructed finger of 9 patients was similar to that of the uninfected side; the flap two-point discrimination was 5.0-7.5 mm; the replantation score and MHQ results were satisfactory. The toenail of the donor site grew well, and no deformity or pain with walking was noted.Conclusions:The free toenail flap was used to treat fingertip defects, with satisfactory clinical results in repairing tissue defects, reconstructing nail bed and maintaining finger length.
ABSTRACT
Abstract Objective Various modalities have been suggested to manage mallet fractures; however, inappropriate treatment can lead to extension lag, a swan neck deformity, or arthritis of the distal interphalangeal joint (DIPJ). The current study aimed to evaluate the results (functional, radiological, and complications) of open reduction and internal fixation (ORIF) of mallet fractures using low-cost hook plates fabricated from low-profile titanium mini plates. Methods A prospective case series of 17 consecutive patients (average age of 32.3 years) with mallet fractures (six were Wehbe Type IB and 11 were Wehbe Type MB). Eleven (64.7%) were males. The affected hand was dominant in all patients, and the affected digit was the index in 6 (35.3%), the ring in 5 (29.4%), the small in 3 (17.65%), and the middle in 3 (17.65%) patients. The same fellowship-trained hand surgeon performed all surgeries. Results The average operative time was 37.65 minutes. After an average follow-up of 10.94 months (range 6-27), the average DIPJ motion was 50º º (range 20º-70º), the extensor lag was noted in 4 (23.5%) patients, and complications were reported in 6 (35.29%) patients. According to Crawford criteria, 6 (35.3%) patients achieved excellent results, 7 (41.2%) achieved good results, and 4 (23.5%) achieved fair results. Conclusion The modified hook plate technique for fixation of mallet fractures is a beneficiai, economical, yet demanding technique that adequately provides stable fixation to allow early DIPJ motion with acceptable functional outcomes.
Resumo Objetivo Diversas modalidades têm sido sugeridas para o tratamento de fraturas em martelo; no entanto, o tratamento inadequado pode causar retardo de extensão, deformidade em pescoço de cisne ou artrite da articulação interfalangiana distal (AIFD). Este estudo teve como objetivo avaliar os desfechos (funcionais, radiológicos e complicações) da redução aberta e fixação interna (RAFI) das fraturas em martelo com placas de gancho de baixo custo fabricadas com mini placas de titânio de baixo perfil. Métodos Série de casos prospectivos de 17 pacientes consecutivos (idade média de 32,3 anos) com fraturas em martelo (seis do tipo IB e 11 do tipo IIB de Wehbe). Onze (64,7%) pacientes eram do sexo masculino. A mão acometida era a dominante em todos os pacientes, com acometimento do dedo indicador em seis (35,3%), anelar em cinco (29,4%), mínimo em três (17,65%) e médio em três (17,65%) pacientes. O mesmo cirurgião de mão experiente realizou todas as cirurgias. Resultados O tempo operatório médio foi de 37,65 minutos.

ABSTRACT
Abstract Objective To evaluate the biomechanical properties of the "figure-of-eight" and Kessler suture techniques for tendons. Methods Flexor tendons of porcine fingers were divided into two groups with triple central "figure of eight" sutures (six passages) and Kessler sutures (two passages) associated with simple and continuous peripheral sutures, and submitted to continuous longitudinal mechanical tests, to obtain the mechanical properties of maximum load and energy at maximum load. Results The mean maximum load and energy at maximum load in the "figure-of-8" suture were of 63.4 N and 217.3 N.mm respectively; in the Kessler suture, the values were of 34.19 N and 100.9 N.mm respectively. The statistical analysis indicated that the "figure-of-eight" suture is mechanically superior to the Kessler technique. Conclusion Under the conditions of this experiment and in the flexor tendon of porcine fingers, the triple "figure-of-eight" suture (six passages) is more resistant than the Kessler suture (two passages). The "figure-of-eight" suture with six passages enables active movement in the immediate rehabilitation of the flexor tendon repair of the finger, with little risk of rupture or suture spacing.

BACKGROUND: Full-thickness nail bed defects with significant exposure of the distal phalanx are typically challenging to reconstruct. We describe a novel method of nail bed defect reconstruction using a thenar fascial flap combined with nail bed grafting. METHODS: Full-thickness nail bed defects were reconstructed in a 2-stage operation involving the placement of a thenar fascial flap and subsequent nail bed grafting. A proximally-based skin flap was designed on the thenar eminence. The flap was elevated distally to proximally, and the fascial layer covering the thenar muscle was dissected proximally to distally. The skin flap was then closed and the dissected fascial flap was turned over (proximal to distal) and inset onto the defect. The finger was immobilized for 2 weeks, and the flap was dressed with wet and ointment dressings. After 2 weeks, the flap was divided and covered with a split-thickness nail bed graft from the great toe. Subsequent nail growth was evaluated on follow-up. RESULTS: Nine patients (9 fingers) treated with the novel procedure were evaluated at follow-up examinations. Complete flap survival was noted in all cases, and all nail bed grafts took successfully. Five outcomes (55.6%) were graded as excellent, three (33.3%) as very good, and one (11.1%) as fair. No donor site morbidities of the thenar area or great toe were observed. CONCLUSIONS: When used in combination with a nail bed graft, the thenar fascial flap provides an excellent means of nail bed reconstruction.

ABSTRACT
SUMMARY OBJECTIVE To report the surgical procedures and efficacy of using medial plantar venous flap for the repair of soft tissue defects of the fingers. Methods From March 2010 to April 2012, medial plantar venous flaps were harvested to repair the wounds of 31 fingers in 29 cases. Among them, there were 13 middle fingers with defects at the tips in 11 cases, 7 fingers with defects in the dorsal part in 7 cases, and 11 fingers with defects in the finger pulp in 11 cases. The size of the defects ranged from 1.2cm×1.5 cm to 2.5cm × 3.5cm. Medial plantar venous flaps of 1.5cm × 2cm - 3×4 cm were harvested. Full-thickness skin grafts were adopted for the donor areas. RESULTS All 31 flaps survived, except for 1 flap with arterial crisis and 2 cases with venous crisis. These conditions were timely corrected by secondary anastomosis of artery and vein and the flaps survived. The wounds and the donor areas achieved healing by the first intention. All grafted skins survived. Postoperative follow-up was conducted for 26 fingers in 24 cases for 4-12 months, excluding 5 cases with lost follow-up. The dorsal part of the damaged fingers had normal morphology, and the skin color and texture were similar to those of the normal skin. After the repair of defects in the fingertip and pulp, fingerprints appeared, and the protective sensation was restored. CONCLUSION The soft tissue defects of the fingers can be satisfactorily repaired with medial plantar venous flap, and little damage is caused to the donor area. This method is proven effective for the repair of soft tissue defects of the fingers.
RESUMO OBJETIVO Relatar os procedimentos cirúrgicos e a eficácia do uso de retalhos plantares mediais venosos para reparo de defeitos de tecidos moles dos dedos. METODOLOGIA De março de 2010 a abril de 2012, foram colhidos retalhos plantares mediais venosos para reparar ferimentos de 31 dedos em 29 casos. Entre eles, 13 dedos médios com defeitos nas pontas em 11 casos, 7 dedos com defeitos na parte dorsal em 7 casos e 11 dedos com defeitos na polpa digital em 11 casos. O tamanho dos defeitos variava de 1,2 cm × 1,5 cm a 2,5 cm × 3,5 cm. Foram colhidos retalhos plantares mediais venosos de 1,5 cm × 2 cm a 3 cm × 4 cm. Foram adotados enxertos de pele de espessura total na área doadora. RESULTADOS Todos os 31 retalhos sobreviveram, com exceção de 1 retalho com crise arterial e 2 casos com crise venosa. Esses problemas foram corrigidos a tempo com anastomoses secundárias das artérias e veias e os retalhos sobreviveram. Os ferimentos e áreas doadoras atingiram cicatrização por primeira intenção. Todos os enxertos de pele sobreviveram. Foi realizado acompanhamento pós-operatório em de 26 dedos em 24 casos por 4 a 12 meses, sendo que dos casos tratados 5 não tiveram acompanhamento. As partes dorsais dos dedos lesionados apresentaram morfologia normal, com cor e textura da pele muito similares a da pele normal. Após o reparo dos defeitos nas pontas e polpas digitais, impressões digitais apareceram e a sensação protetora foi restaurada. CONCLUSÃO Os defeitos de tecido mole dos dedos podem ser reparados de forma satisfatória com retalhos plantares mediais venosos, com poucos danos à área doadora. Este método mostrou se eficaz para o reparo de defeitos de tecido mole dos dedos.

ABSTRACT Objective: To measure the reliability of Albertoni's classification for mallet finger. Methods: Agreement study. Forty-three radiographs of patients with mallet finger were assessed by 19 responders (12 hand surgeons and seven residents). Injuries were classified by Albertoni's classification. For agreement comparison, lesions were grouped as: (A) tendon avulsion; (B) avulsion fracture; (C) fracture of the dorsal lip; and (D) physis injury-and subgroups (each group divided into two subgroups). Agreement was assessed by Fleiss's modification for kappa statistics. Results: Agreement was excellent for Group A (k = 0.95 (0.93-0.97)) and remained good when separated into A1 and A2. Group B was moderate (k = 0.42 (0.39-0.44)) and poor when separated into B1 and B2. In the Group C, agreement was good (k = 0.72 (0.70-0.74)), but when separated into C1 and C2, it became moderate. Group D was always poor (k = 0.16 (0.14-0.19)). The general agreement was moderate, with (k = 0.57 (0.56-0.58)). Conclusion: Albertoni's classification evaluated for interobserver agreement is considered a reproducible classification by the method used in the research.

Métodos: Foi feita uma avaliação por meio de questionário no qual foram avaliadas 43 radiografias em perfil da articulação interfalângica distal de dedos da mão, com lesão tipo dedo em martelo. Todas as lesões foram caracterizadas pela classificação de Albertoni, por 19 entrevistados (12 cirurgiões de mão e sete residentes). Foi então avaliada a concordância com o coeficiente Kappa generalizado, separadas por grupos - (A) avulsão tendínea; (B) fratura avulsão; (C) fratura do lábio dorsal e (D) lesão fisária - e por subgrupos (cada grupo dividido em 1 e 2). Resultados: A concordância foi excelente para o grupo A (k = 0,95 [0,93-0,97]) e manteve-se boa quando separados em A1 e A2. No grupo B, a concordância foi moderada (k = 0,42 [0,39-0,44]), e foi ruim quando separada em B1 e B2. No grupo C, a concordância foi boa (k = 0,72 [0,70-0,74]), mas quando separada em C1 e C2 se tornou moderada. No grupo D foi sempre ruim (k = 0,16 [0,14-0,19]). A concordância geral foi moderada (k = 0,57 [0,56-0,58]). Conclusão: Pela avaliação da concordância geral, a classificação de Albertoni é considerada reprodutível pelo método usado na pesquisa.

Objective To explore the clinical effect of free chimeric bone flap based on the superficial pal-mar branch of radial artery to repair finger composite tissue defects. Methods From July, 2013 to January, 2016, 9 cases of finger composite tissue defect were repaired by free chimeric bone flap from the wrist crease area. The flap and bone flap were taken with the superficial palmar branch of the radial artery during the operation. The area of the flap was 1.5 cm×4.0 cm to 3.5 cm×6.5 cm, and the size of the bone flaps were 0.5 cm×1.0 cm×1.5 cm to 1.0 cm × 2.5 cm × 3.5 cm. Regular followed-up was done after the operation. Results Nine cases of chimeric bone flap survived well, and the average healing time of bone flap was 1.6(1.5-3.0) months. The function and appearance of the patients recovered well. The scars on the donor area was slight. The average two-point discrimination of flap was 6.6 (5.3 to 8.6) mm at 6 months after operation. According to the Evaluation Criteria of Thumb and Finger Reconstructive Function Assessment of the Upper Limb of the Chinese Medical Association, 7 cases were superior, 1 was good, 1 was medium. Conclusion The free chimeric bone flap pedicled with superficial palmar branch of radial artery can si-multaneously repair soft tissue and bone defects. It helps shorten the course of disease and speed up the recovery of finger function.It is a new choice to repair finger tissue defects.
ABSTRACT
Objective@#To report the operation methods and clinical effects of repairing finger tip defect with the free tibial dorsal nerve flap of the second toe.@*Methods@#13 patients with finger tip defects were repaired by the tibial dorsal nerve flap of the second toe. The area of finger tip defect was 2.5 cm×1.5 cm-1.3 cm×1.0 cm, and the area of cutting flap was 2.7 cm×1.7 cm-1.5 cm×1.1 cm. All donor site defects on the second toe were covered with full-thickness skin graft.@*Results@#There were 13 cases in this group, and all the flaps and skin grafts were survived. Postoperative follow-up ranged from 6 to 18 months, with an average of 13 months. The appearance of the fingers was satisfied and the sensory recovery was good. Two-point discrimination of the flaps returned to 7-13 mm, with an average of 9 mm. According to the total active move(TAM)scale, results were excellent in 11 fingers, good in 1 finger, and fair in 1 finger. The donor site skin graft was well healed, the second toe pulp was full, and the two-point discrimination of the toe pulps were 6-10 mm, with an average of 8 mm.@*Conclusions@#Compared to the traditional method of repairing finger tip defect with the tibial inherent nerve flap of the second toe, our new method can reduce the damage to the donor site, and we can repair finger tip defect as well as the traditional one at the same time. So it was a better operative method to repair finger tip defect with the tibial dorsal nerve flap of the second toe.
ABSTRACT
The flexor tendon and pulley system injuries of fingers are relatively common.Injuries to those structures may lead to different degrees of dysfunction,and some injuries may be missed or misdiagnosed in its early stage,resulting in delayed functional recovery,and reduced quality of life.The article is to describe the normal anatomic structure,mechanisms of injury and its imaging features,and the related research progress of the finger flexor tendon system.
ABSTRACT
Objective To explore the application and clinical effect of blood bridge venous flap in finger wound with proper palmar digital artery defect. Methods From February,2007 to September,2016,11 cases of fin-ger wound with artery defect were repaired with forearm vein free flap by the way of bridging blood vessels. The time from injury to surgery was 1.5 to 6 hours(average 2.5 hours).Vascular defect length was 1.4 to 3.4 cm(average 2.3 cm). 8 cases were bridged the unilateral digital artery and 3 cases were bridged the both side. The area of skin flap was 1.5 cm × 2.0 cm to 2.2 cm × 3.5 cm and the donor site was sutured directly. Results One case appeared necrosis in marginal part and healed after dressing change. The other flaps and finger survived and the incisions healed well.All the 11 cases were followed up after operation. The follow-up time ranged from 6 to 20 months, aver-aged 10 months. The color and texture were well,the sensation of temperature, pain and tactile were recovered, and the flap had good contour. According to TAM system evaluation method: 6 cases got excellent results,4 cases were good,1 case was poor. The donor site only had a linear scar and the flexion and extension of wrist were not limited. Conclusion Flow bridging venous flap can reconstruct the finger blood and repair the wound simultaneously. To the finger with nerve or tendon defect,bridged with the cutaneous nerve or palmaris longus tendon can also get satisfactory result.
ABSTRACT
Objective To study the surgical techniques and the clinical curative ettect of the reconstruction of adjacent large finger pulps with the modified sensate free proximal ulnar artery perforator flap.Methods From February,2013 to May,2016,20 fingers in 10 patients with adjacent large finger pulp defects crossing the DIP joint were reconstructed by the modified senate free proximal ulnar artery perforator flap.All the pulps of every patient were recovered by 1 flap in the first stage and the artificial syndactyly of two digits was divided in 7 weeks after the flap transfer in the second stage.In order to reconstruct the sensation of two pulps in each patient,firstly both of the proximal and distal ends of the cutaneous nerve in flaps were dissected and anastomosed with the most lateral and medial palmar digital nerves of two adjacent fingers respectively,which were divided into 2 groups.Secondly the cutaneous nerve in the middle part of flap was cut and the two ends were anastomosed with the other two palmar digital nerves in the second surgery.There were 8 fingers in 4 patients with the index and middle finger pulp defects,12 fingers in 6 patients with the middle and ring finger defects.The flap size was from 5.0 cm×3.5 cm to 5.5 cm×4.0 cm,and the perforator artery was anastomosed with the palmar digital artery in 6 cases and with the joint branch of digital artery in 4 cases.Results Nine flaps survived uneventfully except the venous congestion was found in 1 flap which was salvaged successfully by acupuncture bleeding.Also,no congestion or ischemia of all the 20 pulp flaps occurred right after releasing the artificial syndactyly.The time of followed-up was from 11 months to 32 months with the average of 17 months after the second surgery.The static two point discrimination of the 2 groups of the sensate pulp flap was (7.3 ± 1.2) mm and (8.6 ±2.4) mm respectively.There was no significant difference between groups (P > 0.05).These 20 pulp flaps were also assessed by the Semmes-Weinstein monofilament test with the result of diminished light touch in 14 pulps and diminished protective touch in 6 pulps.The total active motion in all 20 fingers was (248.0±4.5) °.No patients suffered cold intolerance and local pain but 1 had hypersensitiveness in the pulp flap.Conclusion The modified sensate free proximal ulnar arte~ perforator flap is a practical alternative for the reconstruction of two large adjacent pulps with satisfactory functional and aesthetic outcomes.
