Progress in diagnosis and treatment of low-energy Lisfranc injuries / 国际外科学杂志

With the increasing of athletic injuries every year, the incidence of low-energy Lisfranc injuries has also increased. The clinical manifestations of this type of injury are often insidious, and the detection rate of regular imaging techniques is low, as a result, the clinical misdiagnosis rate is relatively high. Once the diagnosis and treatment are delayed, it may result in malunion or traumatic arthritis, leading to pain and functional disability, seriously affecting the patient′s quality of life, and ultimately requiring joint fusion for salvage. In view of this, this article will review the progress in diagnosis, classification and treatment of low-energy Lisfranc injuries to improve the clinical outcomes of such injuries.

Surgical treatment of chronic Lisfranc injuries: short- and mid-term clinical outcomes / 中华创伤骨科杂志

Objective:To explore the short- and mid-term clinical outcomes of surgical treatment of chronic Lisfranc injuries.Methods:A retrospective analysis was conducted of the clinical and imaging data of the 19 patients with chronic Lisfranc injury who had been treated surgically from April 2013 to September 2020 at Department of Foot and Ankle Surgery, Beijing Jishuitan Hospital. There were 13 males and 6 females, aged from 25 to 58 years (mean, 49 years). The median course of disease before operation was 24 months (from 3 to 312 months). All patients underwent fusion of the 1st, 2nd and 3rd tarsometatarsal joints (TMTJ) plus reduction and fixation or arthroplasty of the 4th and 5th TMTJ by the same surgeon. The clinical outcomes were evaluated by comparison of the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score, visual analogue scale (VAS) and Lublin score between pre-operation and the final follow-up and by Likert satisfaction scale and post-operative complications as well.Results:The 19 patients were followed up for (66.1±23.2) months (from 12 to 104 months). At the final follow-up, the AOFAS midfoot score was 87 (79, 90), the VAS score 1 (0, 2), and the Lublin score 70 (60, 75), all significantly improved compared with their preoperative corresponding values [51 (44, 63), 4 (4, 6) and 50 (40, 55), respectively] ( P<0.05). Sixteen patients were satisfied with their surgery. Fusion was not healed in 3 cases; plate breakage happened in one case but none of the cases had infection or other complications related to the skin or wound. Conclusion:Fusion of the 1st, 2nd and 3rd TMTJ plus reduction and fixation or arthroplasty of the 4th and 5th TMTJ can lead to good short- and mid-term clinical outcomes in the surgical treatment of chronic Lisfranc injuries.

Selective column arthrodesis based on three-column theory for malunion of Lisfranc injury / 中华创伤骨科杂志

Objective:To investigate the mid-term clinical outcomes of selective column arthrodesis based on the three-column theory in the treatment of malunion of Lisfranc injury.Methods:The 28 patients with malunion of Lisfranc injury were analyzed retrospectively who had been treated by selective column arthrodesis at Department of Orthopedic Surgery, The Second Affiliated Hospital, Zhejiang University School of Medicine from January 2011 to January 2020.They were 18 males and 10 females, with an average age of 37.2 years(from 18 to 65 years). Twelve left and 16 right sides were affected. According to Myerson's three-column classification, one case was medial column injury (type A), 4 ones middle column injury (type B), 7 ones medial plus middle columns injury and 16 ones three-column injury. Medial column arthrodesis was conducted in 7, middle column arthrodesis in 4 and medial plus middle columns arthrodesis in 17. The American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score and visual analogue scale (VAS) were compared between preoperation and the last follow-up to evaluate the improvements in foot function and pain. The operation-related complications were recorded.Results:All patients were followed up for an average of 35.6 months (from 18 to 60 months). The AOFAS midfoot score increased from 43.1±4.1 at pre-operation to 84.1± 7.4 at the last follow-up and the VAS score decreased from 5.7±1.3 at pre-operation to 2.0±0.9 at the last follow-up (both P<0.001). The wounds healed in 28 patients, 3 of whom had postoperative wound exudation but responded to dressing change. There were no such complications as injury to the deep peroneal nerve or deep venous thrombosis. The internal fixation was removed in 5 patients at about one year after arthrodesis. Conclusion:Selective column arthrodesis based on the three-column theory can result in satisfactory med-term clinical outcomes in the treatment of malunion of Lisfranc injury.

Plantar approach for Lisfranc injury: an anatomical study and preliminary clinical application / 中华创伤骨科杂志

Objective:To explore the safety, efficacy and preliminary clinical application of the single plantar approach or in combination with the dorsalis pedis approach in the treatment of Lisfranc injury with poor dorsalis pedis soft tissue, metatarsal avulsion fracture or complicated multi-column lesions.Methods:(1) Six fresh cadaveric specimens of adult foot were collected and dissected through the plantar approach in order to determine the skin incision of the plantar approach and the safe area for plate-screw internal fixation, including start-stop points and courses of plantar nerves, blood vessels, tendons and ligaments, followed by plate-screw fixation on the specimens. (2) After feasibility of the plantar approach was confirmed by our anatomical study, it was used to treat the 3 patients who were admitted to Department of Orthopedics, The Third Hospital Affiliated to Southern Medical University between September 2020 and November 2021 for Lisfranc injury with severe necrosis due to dorsalis pedis skin contusion or metatarsal base avulsion fracture. They were 2 males and one female, with an average age of 51 years (from 34 to 68 years). The preliminary clinical efficacy was evaluated in terms of visual analogue scale (VAS), midfoot score of American Orthopaedic Foot and Ankle Surgeons (AOFAS), Maryland score, Kofoed score, fracture healing at the last follow-up and postoperative complications.Results:(1) Regarding the anatomical exposure range, the metatarsal side of the first metatarsal wedge joint was exposed medially and the metatarsal side of the third metatarsal wedge joint was exposed laterally; the peroneus longus tendon, Lisfranc plantar ligament and interosseous ligament were explored. X-ray films after the simulated operation showed satisfactory plate positions. (2) As for the preliminary clinical application, all patients were followed up for 6 to 14 months (mean, 11 months). At the last follow-up, the VAS score ranged from 0 to 1 (mean, 0.5), AOFAS score from 85 to 92 (mean, 89), Maryland score from 93 to 96 (mean, 95), and Kofoed score from 92 to 95 (mean, 94). There were no early complications such as fascial compartment syndrome, skin necrosis or infection. All fractures got united, with no complications like traumatic arthritis, muscle atrophy or screw loosening.Conclusion:Testified by the anatomical study, the plantar approach can be used to treat Lisfranc injury with poor dorsalis pedis soft tissue, metatarsal avulsion fracture or complicated multi-column lesions, leading to safe, effective and satisfactory clinical outcomes.

Screw-plate fixation versus non-cannulated screw fixation for Lisfranc ligament injury: a 3-D finite element analysis / 中华创伤骨科杂志

Objective:To compare biomechanical stabilities between screw-plate fixation and non-cannulated screw fixation for Lisfranc ligament injury by a 3-D finite element analysis.Methods:A 3-D model of a healthy foot was developed from computed tomography images. The 1st and the 2nd dorsal tarsometatarsal ligaments and Lisfranc ligament were cut in the 3-D model of a healthy foot to establish a Lisfranc ligament injury model, in which screw-plate fixation (with 2 locking plates and 8 standard screws and one non-cannulated screw) and non-cannulated screw fixation (with 3 non-cannulated screws) for Lisfranc ligament injury were simulated respectively. Finite element analyses were carried out by Abaqus 6.14 software after loads were added in the 3-D models of screw-plate fixation and non-cannulated screw fixation for Lisfranc ligament injury. The overall stress-strain nephogram, the stress distribution and displacement of the foot bone, and the stress distribution on the internal fixation system were compared between the 2 kinds of models.Results:Under the same load, the stress of the whole screw-plate fixation was concentrated on the fixators, and the stress of the non-cannulated screws was also greater than that of the bones. In both models, the strain of the whole foot led to arch collapse, especially in the medial column. The maximum stress on the screw holes in the medial and middle columns in the screw-plate fixation model was 39.91 MPa, smaller than that in the non-cannulated screw fixation model (53.13 MPa). The relative displacement of the first metatarsal joint in the screw-plate fixation model was 8.515 × 10 -1 mm, much greater than that in the non-cannulated screw fixation model (3.893 × 10 -1 mm). Stress concentration was observed in both models. The stress of the screw-plate system was concentrated on the fibular side of the middle section of the plate used to fix the first tarsometatarsal joint, decreasing towards both ends. The maximum stress of the non-cannulated screws was located in the middle of the medial column screw for fixation of the first tarsometatarsal joint, significantly greater than those of the both ends. The maximum stress of the screw-plate system was 239.5 MPa, smaller than that of the non-cannulated screws (256.8 MPa). Conclusions:Non-cannulated screw fixation demonstrates a greater biomechanical stability for Lisfranc ligament injury than screw-plate fixation. However, the former may have a higher risk of screw breakage because it bears a greater stress.

Surgical treatment of fracture of the first metatarsal base with plantar plate via the first metatarsal medial approach / 中华创伤骨科杂志

Objective:To investigate the outcomes of the surgical treatment of fracture of the first metatarsal base with plantar plate via the first metatarsal medial approach.Methods:A retrospective study was conducted of the 12 patients who had been treated for fracture of the first metatarsal base from January 2016 to December 2018 at Department of Trauma Orthopaedics, Renji Hospital. They were 8 men and 4 women, with an average age of 39.6 years (from 27 to 54 years). The fracture affected the left foot in 5 cases and the right foot in 7. Their fracture of the first metatarsal base and tarsometatarsal joint instability were fixated by plantar plate via the first metatarsal medial approach, and reduction and fixation was also conducted via a dorsal incision when other metatarsotarsal joint injuries were combined. Postoperative X-ray follow-ups were performed regularly. The American Orthopedic Foot and Ankle Society (AOFAS) midfoot scores, visual analogue scale (VAS) pain scores and complications were recorded at the final follow-up.Results:All the patients were followed up for 12 to 19 months (mean, 15.1 months). Primary incision healing was observed in all the 12 patients. No complications like skin necrosis, infection or neurovascular lesion occurred. Fracture union was achieved in all the 12 patients after 12 to 14 weeks (average, 12.6 weeks). At the final follow-up, all the patients could walk with full weight-bearing, the plantar flexion and dorsiflexion of the ankle and the muscle strengths of varus and valgus were normal, and the X-ray film showed that reduction of the tarsometatarsal joint was not lost. At the final follow-up, the AOFAS midoot scores ranged from 82 to 96 (mean, 88.9) and the VAS scores from 0 to 3 (mean, 1.2).Conclusion:Plantar plate fixation via the first metatarsal medial approach can result in satisfactory outcomes for fractures of the first metatarsal base, especially for those with a major fracture fragment at the metatarsal planter side.

Short-term effectiveness of Endobutton plate in reconstruction of Lisfranc ligament / 中国修复重建外科杂志

Objective: To observe the short-term effectiveness of Endobutton plate in the reconstruction of Lisfranc ligament in tarsometatarsal joint injury. Methods: Between March 2015 and July 2018, 18 patients with tarsometatarsal joint injuries were treated with Lisfranc ligament reconstruction by Endobutton plate. There were 12 males and 6 females with an average age of 32.5 years (range, 16-55 years). The causes of injury were traffic accident in 8 cases, falling from height in 3 cases, crushing by a heavy objective in 4 cases, and spraining in 3 cases. There were 10 cases of Myerson type A, 4 of type B1, 2 of type B2, 1 of type C1, and 1 of type C2. The interval between injury and operation ranged from 3 to 9 days (mean, 4.9 days). X-ray examination was performed regularly after operation to measure the distance between the first and the second metatarsal joints, and the visual analogue scale (VAS) score was used to evaluate the pain relief. At last follow-up, the reduction of tarsometatarsal joint was evaluated by measuring and comparing the height of the affected and healthy arches. The foot function was evaluated according to the American Orthopaedic Foot and Ankle Society (AOFAS) score. Results: The average follow-up time was 15.8 months (range, 10-28 months). All incisions healed by first intention. X-ray reexamination showed that there was no screw loosening or plate fracture. There were significant differences in the distance between the first and the second metatarsal joints and VAS score at 3 months after operation, before removal of the internal fixator, and at last follow-up when compared with preoperative values ( P0.05). At last follow-up, there was no significant difference in the arch height between affected foot [(5.3±0.2) mm] and healthy foot [(5.4± 0.3) mm] ( t=1.798, P=0.810). The AOFAS score of foot function was 89.5±7.3 with excellent in 12 cases, good in 4 cases, and fair in 2 cases. The excellent and good rate was 88.9%. Conclusion: The reconstruction of Lisfranc ligament with Endobutton plate can stabilize the tarsometatarsal joint and achieve satisfactory foot function at early stage.

Effectiveness of open reduction and internal fixation for acute and delayed occult Lisfranc injuries / 中国修复重建外科杂志

Objective: To evaluate the effectiveness of open reduction and internal fixation (ORIF) in treatment of acute and delayed occult Lisfranc injuries. Methods: A retrospective review of 26 patients with occult Lisfranc injuries who were treated with ORIF between July 2010 and July 2015 was applied. Fourteen patients were treated within 6 weeks after injury (acute group) and 12 patients were treated after 6 weeks of injury (delayed group). There was no significant difference between the two groups in gender, age, affected sides, and preoperative visual analogue scale (VAS) score, American Orthopedic Foot and Ankle Society (AOFAS) score, and physical and mental scores of Study Short Form 12 Health Survey (SF-12) ( P0.05). The satisfaction rates were 100% and 83.3% (10/12) in acute group and delayed group, respectively. The internal fixators were removed in 20 patients (11 cases in acute group and 9 cases in delayed group) at 9-24 months after operation (mean, 14.5 months). The results of X-ray films showed no traumatic osteoarthritis, midfoot collapse, internal fixation failure, or reduction loss during follow-up period. Conclusion: ORIF is an ideal method for both acute and delayed occult Lisfranc injuries and can obtain the similar effectiveness.

Pseudoaneurysm of Dorsalis Pedis Artery Following Lisfranc Surgery: A Rare Complication

@#Aneurysm and pseudoaneurysm of the dorsalis pedis artery remains to be rare vascular entities with a reported incidence of 0.5% of peripheral arterial aneurysms. Only, few cases were reported. The formation of pseudoaneurysm is commonly associated with fracture, laceration wound or iatrogenic arterial injury. An arterial injury that coincides with pseudoaneurysm can initially be missed due to lack of clinical findings. Prompt recognition remains paramount to reduce morbidity and mortality. Here, we present a rare complication of a commonly performed orthopaedic procedure in a young male who presented with painful swelling over left foot after he was involved in an industrial injury. He presented again with a pulsating mass over his left foot after 2 months post fixation surgery of a Lisfranc injury. He was treated conservatively with compression bandage and able to regain to his normal activity after the treatment initiated.

Undisplaced subtle ligamentous Lisfranc injuries, conservative or surgical treatment with percutaneous position screws? / 中华创伤杂志(英文版)

PURPOSE@#Undisplaced subtle ligamentous Lisfranc injuries are easy to miss or underestimate, and many cases are treated without surgical fixation. It has not yet widely known whether conservative treatment for undisplaced subtle ligamentous Lisfranc injuries may lead to a poor outcome. The purpose of this study is to compare the outcomes of conservative versus surgical management (percutaneous position screw) of undisplaced subtle ligamentous Lisfranc injury.@*METHODS@#We analysed 61 cases in this retrospective study, including 38 males and 23 females. Forty-one patients were managed conservatively, while 20 patients received surgical treatment involving minimal invasive percutaneous position screw. American orthopaedic foot &ankle society (AOFAS), foot function index (FFI, including FFI disability, FFI pain score and activity limitation scale) scores, Maryland foot score and short form-36 (SF-36) were recorded and compared after a follow-up of 10-16 months (average 12.3).@*RESULTS@#Patients in the surgical management group had higher scores in all evaluation methods (p < 0.05). The complications in the conservative management group had higher incidence, mainly including secondary diastasis (34.1% vs. 5.0%), joint stiffness after 3 months (82.9% vs. 0%), and secondary arthrodesis (12.2% vs. 0%). The highest rate of complication in surgical management group was temporary forefoot pain (55.0%).@*CONCLUSION@#The results of this study suggest that the outcomes of the surgical management with percutaneous position screw fixation are better than the conservative management to treat undisplaced subtle ligamentous Lisfranc injuries. This study can serve as a resource for orthopaedic surgeons in recognizing and managing such injuries.

Conclusiones: La discapacidad en manos y pies por trastornos neurológicos en pacientes con lepra lepromatosa de más de 5 años de evolución es bastante frecuente, pero asociado a luxofractura de Lisfranc de tipo divergente, por trauma de baja intensidad, no lo es, ya que este tipo de lesión normalmente se produce por traumas de alta energía(AU)

Introduction: Lisfranc joint lesions are produced by high energy traumas, but when they present in patients with Hansen´s disease and damage to the peripheral nervous system, the low intensity repeated traumas can lead to this type of lesion. Objective: To present an interesting case, given a particular association on a patient with Hansen´s disease and a Lisfranc lesion, caused by a low energy trauma. Case presentation: 64 years old Phototype V patient with antecedents of lepromatous Hansen´s disease who presented Lisfranc fracture-dislocation of a divergent type after low intensity repeated traumas, and a septic superadded process. The antecedents, clinical picture, laboratory tests, ultrasounds, radiological study, and the treatment indicated are all analyzed. Conclusions: Disability in hands and feet due to neurological disorders in patients with lepromatous leprosy of more than 5 years of evolution is very frequent, but it is not so frequent when associated to a Lisfranc fracture-dislocation of a divergent type due to low intensity trauma, because this type of lesion is normally caused by high energy traumas(AU)

Análisis de las complicaciones en pacientes con fractura-luxación de Lisfranc / Complication analysis in Lisfranc fracture-dislocation

Resumen: Objetivo: Valorar las complicaciones y secuelas del tratamiento de la fractura-luxación de Lisfranc (FLL). Material y métodos: Se realizó un estudio de cohortes ambispectivo trasversal de 83 pacientes con diagnóstico de fractura-luxación de Lisfranc. Se utilizó un protocolo de recopilación de datos con variables relacionadas con la lesión, parámetros clínicos, terapéuticos, complicaciones y escalas de valoración clínica. Resultados: 66 pacientes (79.5%) presentaron complicaciones tanto precoces como tardías. Las complicaciones precoces sumaron nueve casos de edema postoperatorio, tres de infección superficial, dos de necrosis cutánea que precisó injerto libre de piel (ILPH), uno de lesión vascular, uno de tromboembolismo pulmonar (TEP), uno de pérdida de reducción en el postoperatorio precoz, uno de mala reducción que precisó de nueva intervención. Entre las complicaciones tardías, 41 pacientes (49.40%) presentaron signos radiológicos de artrosis en la articulación tarsometatarsiana, cinco con enfermedad de Sudeck que precisó tratamiento, ocho con descalcificación por desuso, 12 con edema residual, uno con pérdida de reducción en fase tardía, uno con cicatriz hipertrófica y brida retráctil, uno con osteomielitis crónica, uno con seudoartrosis, tres con intolerancia/infección tardía al material de osteosíntesis; también hubo reintervención de siete pacientes en fase de secuelas donde se les realizó artrodesis. No se observó ninguna rotura de material de osteosíntesis. Casi la mitad de los pacientes (49.4%) recibieron algún tipo de indemnización económica tras el accidente. Conclusiones: El tratamiento de las FLL debe realizarse lo antes posible, ya que la estabilización en un breve plazo de tiempo puede ayudar a mejorar los resultados. La reducción anatómica no predice los buenos resultados. Un número importante de pacientes refirió dolor residual.

Analyzing the early complications, we observe 9 cases of postoperatory edema with inflammation and swelling, 3 cases of superficial infection, 2 cases of necrosis cutaneous that precise graft should free of skin (ILPH), 1 case of vascular complication, 1 case of pulmonary embolis (TEP), 1 case of loss of reduction in the precocious postoperatory, 1 case of bad reduction that was necessary new intervention. The late complications presented the following distribution: 41 patients (49.40%) presented radiological signs of degenerative osteoarthritis in the tarsometatarsal joint, 5 cases of Sudeck's disease that needed treatment, 8 cases of decalcification for disuse, 12 cases of edema and residual inflammation, 1 case of loss of reduction in late phase, 1 case of hypertrophic scar with retractable bridle, 1 case of chronic osteomyelitis, 1 case of seudodegenerative osteoarthritis, 3 cases of late intolerance/infection to the osteosynthesis material, reintervention of 7 patients in phase of sequels where they were realized artrodesis. No break of material was observed of osteosynthesis. Almost the half of the patients (49.4%) they received some type of economic indemnification after the accident. Conclusions: The treatment of the FLL must be realized as soon as possible, providing that the general condition of the patient and of the soft parts allows it, since the stabilization in the brief space of time can help to improve the results. The anatomical reduction cannot grant a good result. An important number of patients had residual pain.

Fractura de cuña intermedia asociada a lesión de Llisfranc y escafoides tarsiano. Sustitución con injerto autólogo. Reporte de un caso / Intermedia Wedge fracture associated with Lisfranc injury and tarsal scaphoid. Substitution with autologous graft. A case report

La fractura-luxación de Lisfranc, es poco frecuente (0,2% de todas las fracturas) y pasa inadvertida; la ausencia de tratamiento puede originar una deformidad de pie plano valgo con gran incapacidad y artrosis postraumática. Las fracturas de la cuñas, generalmente están asociadas a otras lesiones, el tratamiento quirúrgico se reserva a determinados casos, y su sustitución está poco documentada en la bibliografía; en las fracturas del cuerpo del navicular es importante su correcto tratamiento por formar parte de la coxa pedis. Se presenta el caso de un paciente que sufrió traumatismo del pie derecho con afectación de las cuñas y pérdida de la integridad ósea de la cuña intermedia(AU)

The Lisfranc fracture-dislocation, are uncommon (0.2% of all fractures) go unnoticed, no treatment can cause a valgus flatfoot deformity with great disability and posttraumatic osteoarthritis (1). Fractures wedge are usually associated with other injuries, surgical treatment is reserved, for certain cases, and replacing this poorly documented in the literature, in fractures of the navicular body is important proper treatment to be part of the pedis coxa. Report the case patient who suffered trauma to the right foot, with an affectation wedges with loss of bone integrity of the intermediate wedge(AU)

Lisfranc Joint Injury / 대한족부족관절학회지

The Lisfranc joint complex is an anatomical association of many bones and articulation, restrained by an even more complex network of ligaments, capsules, and fascia, which must work in concert to provide normal and painless motion. Careful diagnostic workup with high-quality radiographs and computed tomography of the foot are used to diagnose injuries and fractures of this complex. We have to understand the normal anatomy and injury mechanism in order to appropriately treat Lisfranc injuries. Good results have been associated with anatomic reductions of all bones, which was achieved with restoration of proper alignment.

Staged management of missed lisfranc injuries：A report of short-term results / 国际外科学杂志

Objective To analyze the clinical and radiographic outcomes of staged reduction and fixation in a consecutive series of patients with the old Lisfranc injuries. Methods Fifty patients (16 feet) with Lisfranc injuries were treated with staged reduction. Mean duration between injury and surgery was 4. 8month ( 3 to 8 month) . In first stage an external fixator was applied across the Lisfranc joint and distraction was done at 1 milliliter per day to 2 milliliter per day. In the second staged the ORIF ( open reduction and internal fixation) was doneand we were able to reduce all the fractures and dislocations. Extra-Articular screws and staple fixation were used for fixation. We compared categorical variables using Fisher’ s exact test and continuous variables using paired t-test or Wilcoxon signed-rank test. Results All patients were followed up 1 to 3 years ( mean 2. 2 years) in the clinic. The visual analogue scale score averaged 3. 1 points at the final follow-up, the average AOFAS scores for these patients were 55. 8 points ( range, 43 to 98 points), with a significant increase than before surgery ( P=0. 001). The mean duration between two surgeries was 3. 2 weeks (range 2. 5-4. 5 weeks). Anatomic reduction was obtained in all 15 patients. At the last follow-up, 2 patients had lost reduction. Posttraumatic osteoarthritis was observed in 5 patients, and all of them were scheduled for arthrodesis because of persistent pain. Conclusions The study have displayed that staged reduction and Extra-Articular fixation should be considered for old Lisfranc injuries with a good reduction, the firm stability, low risk of intraoperative fracture. The short-term effectiveness is good, but the long-term effectiveness needs further follow-up.
