RESUMEN
Objective:To investigate the clinical effect of perforator flap of distal cutaneous perforator of medial plantar artery in recon struction of destructive defect in the base plane of proximal phalange of great toe.Methods:Twenty-six patients were treated in the Department of Foot and Ankle Surgery of Xuzhou Renci Hospital from September 2017 to December 2021. The patients were 24 males and 2 females, aged 26 to 60 years old. There were 12 defects in left foot and 14 in right foot. All the defects were the residual wounds at the first metatarsophalangeal joint with the defect at 2.0 cm × 3.0 cm - 4.0 cm × 5.0 cm in size. The flaps pedicled with distal cutaneous perforator of the medial plantar artery were used to repair the defects, with a size at 3.2 cm× 4.2 cm in average. Skin grafts were employed to repair the donor sites. Postoperative patient management including lifting the affected limbs and keeping warm, anti-infection, detumescence, anti-coagulation and pain relief.Results:All patients were entered in postoperative follow-up at outpatient clinic for 1-3 years. Twenty-two flaps survived after surgery, except 4 that had dark purple edge indicating venous congestion. Blood supply of the flap was regained after the tension of the flap was relieved by interval suture removal. Appearance of flaps was good, without obvious swelling nor pigmentation, good in elasticity, in hard texture and with good wear resistance. Patients showed no limp of the affected limbs, and without restriction in wearing shoes or walking. The function of feet was evaluated according to the American Orthopedic Foot and Ankle Societ (AOFAS) I50, with 24 patients in excellent and 2 in good.Conclusion:The anatomy of the flap pedicled with distal cutaneous perforator of the medial plantar artery is relatively constant. It provides a blood supply and does not affect the trunk of major artery. The flap has a thick skin cuticle hence it is wear-resistant. This flap provides a choice to the repair of a defect at proximal segment of great toe.

The patients were 111 males and 18 females with an average age of 34(17-59) years old. The sizes of nailbed defect were 0.4 cm×1.1 cm-1.8 cm×2.0 cm, the length of phalange defect was 0.4-1.8 cm, and the sizes of the soft tissue defect were 1.6 cm×1.8 cm-3.2 cm×4.8 cm. Great toe tissue flaps were used to reconstruct the partial defect of distal segment of thumb or fingers after debridement. Wounds of fibular flap of great toe in 77 cases were directly sutured in 17 patients. The donor sites in rest 60 great toes were narrowed first and then repaired with skin grafts in 10 cases, with artificial dermis in 28 cases and with transverse V-Y advancement flaps of ipsilateral great toes for 22 cases. Forty-nine of 52 donor site wounds for hallux toenail flap were repaired with artificial dermis and 3 with free peroneal artery perforator flaps. The method was outpatient follow-up. Postoperative follow-up lasted until July 2022. The check-items for follow-up included: occurrence of necrosis, appearance, shape and texture of the flap, appearance of the reconstructed nails, TPD of the reconstructed digit pulps, tolerance to cold on the scars of flaps, flexion and extension of the reconstructed digits. The healing time of phalanges of the reconstructed digits was evaluated by X-rays. The appearance, sensation, the tolerance to cold of great toe and the movement of donor foot were also assessed.Results:Postoperative follow-up lasted for 18 to 24 months, with an average of 21 months. A total of 128 flaps survived. Necrosis occurred in 1 fibular hallux flap, the necrosis was cured with a reverse digital proper artery island flap. Thereafter, all flaps healed well. The appearance, shape, texture and nails of reconstructed digits were close to the contralateral digits. The reconstructed thumb and finger were evaluated according to Zook, 127 cases were excellent and 2 cases were good.TPD of the pulps of the reconstructed digits was 4-10 mm. The mean score of the Vancouver scar scale(VSS) was 0.6 for scars of the reconstructed digits. The mean score of the Visual analog scale(VAS) was 0.3 for the tolerance to cold. Flexion and extension function recovered well in all the reconstructed digits. According to the Evaluation Criteria of Upper limb Function Hand Surgery Society of Chinese Medical Association, the function of hand was excellent in 127 cases and 1 in each of good and fair. X-rays of all digits showed the phalange healing of the reconstructed digits, with an average healing time of 2 months after surgery, without phalange resorption, infection, nonunion nor stress fracture. There was no difference between the length of the donor great toe and the contralateral toe, except the donor site of the great toe nail root. There was no significant visual difference between the appearance of the donor great toe and the contralateral toe. TPD of the pulps of donor great toe was 4-8 mm. The mean score of the VSS was 1.4 for scars in the donor great toe. The mean score of the VAS was 0.7 for the tolerance to cold of the donor great toe. There was no stress fracture at donor site, and the functions of donor foot were not affected when walking, running, jumping and tiptoeing in all patients.Conclusion:It is an ideal method for reconstructing a partial defect of distal segment of digit by great toe flap. It can not only reconstruct the partial defect of distal segment of the digit, but also results in a good appearance and satisfactory functions of the reconstructed digit. Damage to the donor site is minimum. The length of the donor great toe is unchanged, and it has little impact on sensation and appearance of the donor great toe. Meanwhile, there is no adverse effect on walking, running and jumping with the donor foot.

First, the donor site of the fibular hallux flap was sutured to reduce the size of wound. The width of the remaining wound was 0.4 to 1.6 cm, and the area of the remaining wound was 0.5 cm×0.8 cm-1.6 cm×1.8 cm. Then the remaining wound was repaired with the transverse V-Y advancement flap of the ipsilateral great toe. The distance for transfer of transverse advancement V-Y flap was 0.2-0.8 cm, and the area of the transverse V-Y advancement flap was 1.0 cm×1.4 cm-1.8 cm×2.4 cm. The end of postoperative follow-up was scheduled in July 2021. The follow-up items included: survival of the transverse V-Y advancement flap, wound infection, appearance, shape, texture and sensation of the V-Y advancement flap, pain on the V-Y advancement flap and the great toe, cold tolerance and the scar condition at the donor site of the ipsilateral fibular hallux flap and the V-Y advancement flap, the appearance, sensation and flexion and extension of the great toe at the donor site, other discomforts in the donor site of great toe, walking and other functions affected by the discomforts.Results:The postoperative follow-up lasted from 12 to 18(average of 14) months. All the V-Y advancement flaps survived without infection at the donor sites of the great toe, and donor sites healed primarily. The appearance, shape and texture of the advancement V-Y flap were close to the skin of the same area of the contralateral great toe. The TPD of the V-Y advancement flap and the ipsilateral great toe ranged from 4 to 7 mm. The average score of the Visual analog scale(VAS) was 0.3 and 0.6 respectively in the evaluation of cold tolerance of the advancement V-Y flap and the ipsilateral great toe. The average score of the Vancouver scar scale(VSS) was 0.2 and 1.2 respectively in the scar evaluation of the V-Y advancement flap and the ipsilateral great toe. There was no visual difference between the appearance of the great toe at the donor site and the contralateral toe. There was no pain and other discomfort on the V-Y advancement flap and the ipsilateral great toe. The functions of the donor foot were not affected in walking, running, jumping and tiptoeing in all cases.Conclusion:It is a simple, safe and effective method to repair the donor site of the small-area ipsilateral fibular hallux flap by the transverse V-Y advancement flap of the great toe. It only causes a small wound but the appearance and function of the ipsilateral great toe can be repaired with a transverse V-Y advancement flap of the great toe.
RESUMEN
Objective:To explore a surgical technique and treatment outcomes of the segmentle bridging reconstruction for severed fingers with single segmentle defect by using the free second toe bone-joint composite tissue combined with the great toe flap.Methods:From June 2010 to September 2017, 5 patients suffered from severed segmental defect of finger were treated. According to the defects of bone-joints, blood vessels, nerves, tendons and other soft tissues, the reconstruction surgery was designed to create a Flow-through bridging composite flap pedicled with the first dorsal metatarsal artery or the plantar artery. The blood vessles carried by the pedicle were anastomosed with the vessels in the finger to restore the blood supply to the distal finger while having the defected finger segment reconstructed. A Flow-through bridging composite flap was created by taking the second toe bone-joint composite tissue combined with a C-shaped or half-moon shaped flap from the fibular side of the great toe. Skin graft, retrograde lateral tarsal flap or free perforator flaps were used in 3 cases to repair the donor sites of the great and second toes. Iliac strip was implanted in 2 cases for toe salvage. Kirschner wires were removed 4-6 weeks after surgery followed by functional exercise.Results:All of the 5 reconstructed distal segments of the fingers survived with the healing of fractures in 8-12 week after surgery. The postoperative follow-up lasted 6-36 months and all the patients had the follow-ups at the outpatient clinic. It was found that the maximum flexion of the reconstructed interphalangel joint was 60 degrees together with dorsiflezion. According to the evaluation standard of the reconstructed function for thumb and finger issued by the Hand Surgery Society of the Chinese Medical Association, 3 fingers were in excellent and 2 in good. No obviouse affect on walking was found in all the patients.Conclusion:The free second toe joint composite tissue together with the great toe flap can be used to bridge the single segmental defect of a finger. It restores the blood supply to as well as the appearance of the distal finger, helps the recovery of the reconstructed distal finger. It is an ideal technique in the treatment of a severed distal segment of the finger.
RESUMEN
Objective:To investigate the clinical effect of free fibular flap of great toe without vein in repairing soft tissue defect of finger pulp.Methods:From June 2020 to January 2021, 8 cases of finger pulp soft tissue defect were repaired with free flap of fibular side of great toe without vein, including 6 males and 2 females, with an average age of 32(18-42) years old. The defect area of finger pulp was 1.0 cm×0.5 cm-1.8 cm×0.8 cm. The proper digital artery and digital nerve of the affected finger were anastomosed. All flaps did not carry reflux veins. The donor site of the toe was directly sutured. Postoperative routine anti infection, anti spasm and anticoagulant treatment was performed. Postoperative outpatient regular follow-up.Results:All flaps survived without vascular crisis, and the donor and recipient sites healed in the first stage. All patients were followed-up for an average of 6.4(4-12) months. At the last follow-up, the TPD was 6-8 mm, the hand function was evaluated according to the Trial Standard of Upper Limb Function Evaluation of Hand Surgery Society of Chinese Medical Association. Seven cases were excellent and 1 case was good.Conclusion:The free fibular flap of the great toe can be used to repair the small wound of finger pulp without carrying the draining vein, the flap can still survive. And it can provide a certain reference for the failure of anatomic separation of the draining vein.
RESUMEN
Objective:To summarise the advantages and disadvantages of applying the method of retrograde replantation with an operative position of foot stepping and knee bending for replantation of rotational avulsed and fractured great toes.Methods:From January 2016 to June 2021, 11 rotational avulsed and fractured great toes were replanted with the method of retrograde replantation in an operative position of foot stepping and knee bending. Of the 11 patients, 10 were males and 1 was female, aged 18 to 50 years old with an average of 32 years old. Causes of injury: 5 of driving belt, 4 of machinery crush and 2 of car accident. Injury sites: 4 on left great toes and 7 on right great toes. All of the injuries were with fracture and exposure of proximal tendons of flexor and extensor. Seven patients had the follow-up reviews by outpatient clinic visiting, 2 over mobile phone and 2 via WeChat.Results:After surgery, 9 great toes completely survived and 2 great toes had necrosis. The survival rate of toe replantation was 81.8%(9/11). The operation time was 2 to 3 hours, with an average of 2.5 hours. Postoperative X-ray film showed that 8 to 12 weeks after the operation, the fracture and joint fusion were healed at first stage in the survived toes. All patients were entered in follow-up for 3 to 18 months with 10.5 months in average. The survived great toes were plump and the toenail grown well. At the final follow-up, the static TPD at the toes was 8-12 mm, with an average of 10 mm. There was no effect shown on either walking or running.Conclusion:The retrograde replantation method with an operative position of foot stepping and knee bending for great toe replantation has the characteristics of a good field of view and convenient in operation under microscope, a short operation time, and a high survival rate of replantation.
RESUMEN
PURPOSE: Pediatric intra-articularproximal phalangeal head fractures of the big toe are very rare and few studies on this have been published. The purpose of this study is to present the diagnostic approach and surgical management of these extremely rare fractures, which might be easily underestimated or misdiagnosed.MATERIALS AND METHODS: The study retrospectively reviewed all the patients who were diagnosed as intra-articular proximal phalangeal head fracture of the big toe and who underwent surgical intervention in our institution. The size of the bony fragment and hallux valgus interphalangeus angle were measured on the preoperative X-rays. The size and rotation of the osteochondral fragment, the presence of avascular necrosis, ligamentous injury and soft tissue entrapment were assessed on the preoperative magnetic resonance images (MRIs). The radiologic and functional evaluation were performed at 1 year postoperatively.RESULTS: The average size of the bony fragments measured on the X-rays was 4.1 mm in width and 2.3 mm in length. Two cases showed hallux valgus interphalangeus. Preoperative MRI was performed in four cases and the average size of any osteochondral lesion was 5.3 mm in width, 3.9 mm in length, and 4.7 mm in height. Rotation of the osteochondral fragment was observed in one patient, and soft tissue entrapment was noted in two patients. Postoperatively, successful bony union was achieved in all the patients and the average time to union was 74.4 days.CONCLUSION: Intra-articular proximal phalangeal head fractures of the big toe are very rare and often neglected due to incomplete ossification in the pediatric population. It is important to suspect the presence of this intra-articular fracture and to appropriately implement further evaluation. Nonunion of chronic cases as well as acute fractures can be successfully treated through open reduction and internal fixation using multiple K-wires.

BACKGROUND: It is difficult for surgeons to reconstruct soft tissue defects of the great toe. This report aims to evaluate the utility and efficacy of innervated distally based first dorsal metatarsal artery (FDMA) flap with a wide pedicle for reconstruction of soft tissue defects of the great toe. METHODS: This is a retrospective report. Between January 2015 and December 2017, six cases of skin defect of the great toe were reconstructed with an innervated distally based FDMA flap with a wide pedicle. One case was excluded in this report because of chronic pain on the metatarsophalangeal joint due to osteoarthritis before the injury. A total of five cases were evaluated for flap survival and sensory recovery. The sensory recovery was investigated by two-point discrimination and Semmes-Weinstein monofilament tests. The average age of the selected patients was 40 years (range, 36 to 56 years), and the average size of the defect in the toe was 8.3 cm2 (range, 4 to 13.8 cm2). The average follow-up period was 29.4 months (range, 18 to 38 months). RESULTS: All patients survived without any complications. The average two-point discrimination test value was 8.0 ± 0.89 mm (range, 7 to 9 mm), and the average value obtained from the Semmes-Weinstein monofilament test was 4.53 ± 0.33 (range, 4.17 to 4.93). The average residual pain score evaluated with a visual analog scale was 1 (range, 0 to 2). Two patients complained of stiffness in the great toe below 30° of total range of motion during the early stages after surgery, but this stiffness gradually improved after rehabilitation. The average range of motion of three patients with a remaining metatarsophalangeal joint after surgery was 80° (range, 70° to 90°). All five cases could walk regularly without any unique footwear at the final follow-up. CONCLUSIONS: The innervated distally based FDMA flap with a wide pedicle could be a good alternative method for repair of soft tissue defects of the great toe.

RESUMEN
Objective To identify the routes and branches of the proper plantar digital nerves(PPDN) in the medial of the great toe and its adjoining relationship among the surrounding fascia tissues and organs,which was expected to provide accurate localization of the nerve impingement and possible relevant of anatomical basis for the treatment of nerve entrapment in clinical utility.Methods From December,2016 to January,2019,a total of 54 formalin fixed feet were collected.Fifty of them were performed conventional anatomical procedure,the other 4 were prepared with sectional anatomical technique.The seats and branches of the PPDN in the medial of the great toe were observed;The width and thickness of the nerve were measured at the first metatarpophalangeal joint(FMPJ),along with its proximal and distal sides 0.5 cm.The origin and origin of fascia were observed by foot dissection.Masson staining was used to observe the tissue changes of the nerves in the FMPJ.Results The PPDN of the medial great toe run between the flexor pollicis longus tendon and the abductor pollicis tendon at the proximal,issued (4.21±0.12) final branches.And governed the sensation of the medial half of the great toe.The width of the nerve at the FMPJ was (3.50±0.09) mm,which was significantly increased compared with that of the near [(1.58±0.04) mm] and far [(1.56± 0.03) mm] from the joint.The difference was statistically significant (P＜0.05);The thickness of the nerve in the proximal segment was (0.83±0.04) mm,and that in the distal segment was (0.82±0.03) mm.Compared with that in the FMPJ [(0.67±0.02) mm],the difference was statistically significant (P＜0.05).A deep fascia was observed on the superficial surface of the PPDN at medial great toe,which was stretched between the tendon sheath of the flexor pollicis longus tendon and the tendon of the abductor pollicis muscle.Masson staining showed obvious proliferation of nerve outer mem brane fibers at the metatarpophalangeal joint,the number of nerve fiber bundles increased,and obvious thickening of nerve fiber bundles and nerve fascia.Conclusion Long-term compression can lead to thickening of the epineurium and perineurium,and the superficial fascia is an important factor of thumb pain and numbness caused by the compression of the PPDN at medial of the great toe.
RESUMEN
Hallux valgus is a deformity that causes pain in the first metatarsophalangeal joint. Surgical methods are quite diverse and a range of osteotomies are used at the proximal and distal part of the metatarsal bone and proximal phalange. Fixation methods, such as plate, screw, K-wire, and others have been used in various ways. The fixation device is often removed with various side effects due to the fixation devices. In the case of instruments that are absorbed in vivo, these procedures are not necessary to remove and there is an advantage of not performing the second operation. Three patients were treated, in which a proximal chevron osteotomy was used with a bioabsorbable screw (K-MET™; U&I Corporation).

RESUMEN
This report describes a variation of the tendinous slip of the flexor digitorum longus (FDL) for the great toe. In addition, compositions of the long flexor tendons for all five toes were examined. The tendons of the FDL in the foot were investigated in 66 specimens of embalmed Korean adult cadavers. The tendons of the flexor hallucis longus (FHL) and the FDL with the lumbrical muscles were cut at the calcaneus and the metatarsophalangeal joints and were removed en bloc specifically to observe the FDL and the FHL tendons of the great toe. The tendinous slip of the FDL for the great toe was found bilaterally in the foot of a 52-year-old male. Its prevalence was two of 66 specimens (3.0%). The tendinous slip of the FDL for the great toe passed forward the great toe, and it constituted the superficial portion of the long flexor tendon for the great toe. The tendon of the FHL passed forward to constitute the deep portion of the long flexor tendon for the great toe. Thus, both the tendinous slip of the FDL and the tendon of the FHL composed the long flexor tendon for the great toe. The tendinous slip of the FDL and the tendon of the FHL for the great toe were similar in thickness; thus, each tendinous slip of the FDL and the tendon of the FHL were approximately one-half of the long flexor tendon for the great toe in thickness. The present study demonstrated an anatomical variation of the interconnection between the FHL and the FDL tendons, which will be useful for various surgeries and biomechanical research.

We report on a rare case of an intraosseous epidermoid cyst in the distal phalanx of the great toe with concurrent infection in a 71-year-old woman with diabetes mellitus. The lesion was initially considered simple infectious arthritis and concomitant osteomyelitis in a patient with diabetes. However, after surgery, an intraosseous epidermoid cyst originating from the nail bed and involving the articular surface of the distal phalanx was detected. The epidermoid cyst may have contributed to the infectious arthritis in the interphalangeal joint. The lesion was treated via mass excision, arthrotomy, debridement, and intravenous antibiotics.

Objective To explore the methods of repairing great toe soft tissue defect with the reverse medial pedis island flap with transverse artery of great toe.Methods This study was made up of two parts:an anatomical study and clinical application.In the anatomical study,49 cadaveric feet were injected with red latex and then anostomosis,distribution and external diameters of transverse artery of great toe,the deep branches of the first plantar metatarsal arteries and the deep branches of medial plantar artery were observed.From September 2006 to December 2012,8 cases of soft-tissue defects with the retrograde-flow medial pedis island flaps were harvested to cover the soft tissue defects of great toe.Soft tissue defect was form 2.5 cm × 3.5 cm-3.5 × 4.5 cm.Results There was an arterial circle under the first metatarsophalangeal joint which consisted of transverse artery of great toe,tibial proper plantar digital artery of great toe,fibular proper plantar digital artery of great toe and the distal part of first plantar metatarsal artery.This arterial circle under the first metatarsophalangeal joint and arterial network on the surface of abductor hallucis was responsible for the blood supply of the flap of medial pedis.The diameter of the pedicle was great,and the length of the pedicle was longer than in previous reported.In terms of clinical application,all patients were followed up with the mean of 10 months (range fromn 6-24 months).All flaps survived totally without diabrosis and swelling.The walking and weight-bearing were normal and the blood supply of foot was good.Conclusion Using of arterial circle under the first metatarsophalangeal joint,the medial pedis island flap has a reliable retrograde blood supply.The reverse point of the reverse medial pedis flap moved forward to th interphalangeal joint.This flap should be considered as a preferential way to reconstruct soft-tissue defects of the great toe.
RESUMEN
Presence of one or more digit is called as polydactyly and may manifest singly or with other genetic disorders. The frequency of polydactyly varies widely among populations. It can occur as an isolated condition or as a feature of a congenital condition. Polydactyly is a rare condition, but still rare is in form of triple great toes. We describe a case in a 4‑year‑old child diagnosed as triphalangism foot with no other obvious visible anomaly. Osteoplasty‑combined surgery, which was ideal for anatomical reconstruction. In a 16‑month follow‑up period child recovered very well.

PURPOSE: In case of the failed replantation, if the patients want to preserve the length of amputated stump, toe transfer is the ideal choice. However, reconstruction of these amputated stump with a free flap can be a useful method when the patients refuse sacrificing their toe. Our purpose of this study is to evaluate availability of functional results and patient satisfaction after this procedure. MATERIALS AND METHODS: From March 2008 to February 2012, we reconstructed the amputated stump with free flap by patients demand. Eleven patients were included, medial plantar artery perforator flap in seven cases and great toe pulp flap in five cases. Follow-up range 12 to 24 months and we evaluate patient satisfaction by using a visual analogue scale (VAS; 1=unsatisfied, 5=excellent) and functional recovery by measuring the range of motion of remaining joint at 12 months after operation. RESULTS: During follow-up period, all transferred free flaps survived and no major complications were noted. Range of motion of remaining joint appeared satisfactory result (15degrees to 100degrees). The VAS patient satisfaction score for aesthetic were five in six patients, four in four patients, and three in one patient. CONCLUSION: In case of the failed digital replantation, if patient refuse toe transfer, it could be useful method to reconstruction with the free flap to preserving maximal length of amputated stump.
