Verletzungen der Fußwurzel, Luxationen und Frakturen im Lisfranc-Gelenk

Lisfranc injuries are rare, accounting for under 1% of all fractures. In 90% of cases the dislocation is combined with a fracture, while in the remaining 10% the ligaments only are affected. The injury can present in various ways. Isolated complex foot trauma is not difficult to diagnose, but in more than 20% of all Lisfranc luxations the diagnosis is missed. This is because when confronted with a multiply traumatised patient physicians concentrate on any life-threatening injuries and not on the foot, but the diagnosis of Lisfranc injury is very often missed even after low-energy trauma because the presentation is occult. In addition to the history, knowledge of the condition of the soft tissues and skill in the interpretation of X-rays and also of the results of computer tomography are necessary. The treatment of choice is open reduction and internal fixation with Kirschner wires ore single screws. Concomitant compartment syndrome is present in up to 60% of cases. Good functional results can be achieved by timely diagnosis, early internal fixation with anatomical reduction and consistent management of soft tissue.

Adolescent Lisfranc injury treated with TightRope~(TM):A case report and review of literature

BACKGROUND Lisfranc injuries are rare and can be easily missed. This injury is extremely rare in children, with limited published data. Different treatment options have been described; one of the options in adults is the "mini" TightRope~(TM) Syndesmosis Device that provides non-rigid fixation with impressive results. However, there is no reference regarding the use of this device in children.CASE SUMMARY We describe the case of an 11-year-old girl who sustained a Lisfranc injury of her right foot that was initially missed in the Accident and Emergency department of her local hospital. This case was a ligamentous/periosteal sleeve avulsion type of Lisfranc injury and a percutaneous technique using the "mini" TightRope~(TM)syndesmosis device was used. Clinical and radiological results were excellent at final follow up.CONCLUSION The "mini" TightRope~(TM) syndesmosis device is a promising method of fixation for children with certain Lisfranc injuries. This method has many advantages,including the non-rigid type of the fixation and no need for subsequent metalwork removal.     

Lisfranc injury: A review and simplified treatment algorithm

BackgroundLisfranc injuries encompass large spectrum of injuries varying from low energy to high energy complex fracture dislocations. Whilst multiple complex classification systems exist; these do little to aid and direct the clinical management of patients. Therefore, this study aims to provide a simplified treatment algorithm allowing clinicians to standardise care of Lisfranc injuries.MethodsA comprehensive literature search was performed, and abstracts were reviewed to identify relevant literature.ResultsDelay in diagnosis has a negative impact on outcome. If a Lisfranc injury is suspected and plain radiographs are inconclusive; computed tomography and if necessary magnetic resonance imaging are indicated if there is still an index of suspicion. In the absence of joint dislocation/subluxation management will be determined by stability which can be best assessed by weightbearing radiographs. If stable, injuries can be treated conservatively in a non-weight bearing cast for 6 weeks followed by a period of graduated weight bearing. Evidence is mounting that with regard to unstable purely ligamentous Lisfranc injuries primary arthrodesis (PA) has: better functional outcomes, increased cost effectiveness and reduced rates of return to theatre. With regard to bony unstable Lisfranc injuries more research is required before a single treatment modality - PA or open reduction internal fixation can be advocated, due to the lack of randomized control trials and limited patient follow-up periods in existing studies.ConclusionA simplified treatment algorithm excluding the requirement for complex classifications is suggested. This may help with the diagnosis and management of these injuries. It is our believe that this algorithm will aid health professionals to standardize care for these injuries. Further prospective research trials are required to assess outcomes of different modalities of operative management, particularly with regards to open reduction and internal fixation versus primary arthrodesis for bony Lisfranc injuries.Level of evidenceLevel 5.     

Combined Medial Column Primary Arthrodesis,Middle Column Open Reduction Internal Fixation,and Lateral Column Pinning for Treatment of Lisfranc Fracture-Dislocation Injuries

Lisfranc fracture-dislocation can be a devastating injury with significant long-term sequelae, including degenerative joint disease, progressive arch collapse, and chronic pain that can be potentiated if not effectively treated. We present a case to demonstrate our preferred surgical approach, consisting of combined medial column primary arthrodesis, middle column open reduction internal fixation, and lateral column pinning, with the primary goal of minimizing common long-term complications associated with Lisfranc injuries. We present the case of a typical patient treated according to this combined surgical approach to highlight our patient selection criteria, rationale, surgical technique, and operative pearls. A 36-year-old male who had sustained a homolateral Lisfranc fracture-dislocation injury after falling from a height initially underwent fasciotomy for foot compartment syndrome. The subsequent repair 16 days later involved primary first tarsometatarsal joint fusion, open reduction internal fixation of the second and third tarsometatarsal joints, and temporary pinning of the fourth and fifth tarsometatarsal joints. He progressed well postoperatively, exhibiting an American College of Foot and Ankle Surgeons forefoot score of 90 of 100 at 1 year after surgery with no need for subsequent treatment. Lisfranc fracture-dislocations often exhibit primary dislocation to the medial column and are conducive to arthrodesis to stabilize the tarsometatarsal complex. The middle column frequently involves comminuted intra-articular fractures and will often benefit from less dissection required for open reduction internal fixation instead of primary fusion. We propose that this surgical approach is a viable alternative technique for primary treatment of Lisfranc fracture-dislocation injuries.     

Combined Medial Column Arthrodesis with Open Reduction Internal Fixation of Central Column for Treatment of Lisfranc Fracture-Dislocation: A Review of Consecutive Cases

Lisfranc fracture-dislocations can be devastating injuries with significant long-term sequelae with or without surgical intervention. The main goal of treatment is to minimize the common long-term complications including pain, progressive arch collapse, degenerative joint disease, hardware failure, and reoperation. Partial primary fusion involving the first, second, and third tarsometatarsal joints has become a common approach for primarily dislocation injuries, with open reduction and internal fixation (ORIF) favored for Lisfranc injuries involving fracture. ORIF commonly requires revision surgery for hardware removal or delayed fusion. Major revision creates hardship for the patient due to the prolonged recovery required, and even “simple” hardware removal can be traumatic to local nerve, artery, and tendon structures. A common injury pattern includes the findings of primary dislocation and instability of the first tarsometatarsal joint with oftentimes comminuted fracture to the second and third tarsometatarsal joints, which does not fit the standard surgical approach. We report a review of our preferred surgical approach consisting of medial column primary arthrodesis combined with central column ORIF and lateral column temporary pinning. We undertook an institutional review board-approved review of 35 consecutive Lisfranc injuries treated with this hybrid approach. Mean follow-up time was 22.14?±?22.39 (range 2.5 to 84) months. All but 2 (5.71%) patients had radiographic evidence of union at 10 weeks. Complications included 3 with neuritis, 1 with medial column nonunion that was treated with a bone stimulator, and 1 with revision of second metatarsal nonunion. The present retrospective series highlights our experience with isolated primary fusion of the medial column in both subtle and obvious Lisfranc injuries.     

Plantare Lisfranc-Luxationsfraktur

We report a 30-year-old patient suffering a plantar dislocation fracture after he dropped a heavy weight on his foot. The patient was treated immediately after diagnosis was secured by CT scan. Median approach and dermatofasciotomy of the foot were followed by anatomic reduction of the fractures and the Lisfranc dislocation and fixed by internal osteosynthesis. After 3 months the patient was able to ambulate pain free without walking aids. Plantar dislocation is a very rare direction of comminuted Lisfranc dislocation fractures. The outcome may be favorable with early reduction and stable internal fixation of the fractures. One always has to be aware of the major soft tissue trauma associated with complex Lisfranc dislocation fractures.     

Percutaneous fixation of Lisfranc joint injuries: A systematic review of the literature

ObjectiveThe aim of this systematic review was to present the outcome of Lisfranc joint injuries treated with closed reduction and screw percutaneous fixation.MethodsWe searched in Pubmed and Google Scholar Databases for articles regarding screw percutaneous fixation of Lisfranc injuries. Seven studies in total were found to be compatible to our search, according to PRISMA guidelines. Four of those met the criteria of the review and they were included in the meta-analysis. A total number of 106 patients were separated into five groups according to the type of injury and the mean AOFAS score of each group was calculated. Cases in which percutaneous fixation was converted to open treatment due to poor reduction were not included in the study. In addition we compared the outcome score between types of injury according to Myerson classification as well as between purely ligamentous and osseoligamentous injuries. The characteristics of all seven selected studies, such as kind of screw used for fixation, post operative protocol, complications and outcome are mentioned as well.ResultsAverage AOFAS score was 86,2 for type A, 87,54 for type B, and 85 for type C injuries respectively. In pure dislocation group the average AOFAS score was 86,43 and in fracture dislocation group was 87,36. Good to excellent outcome can be expected in patients with different types of injury according to Myerson classification following percutaneous fixation of lisfranc joint injury. Patients with type B injury or a fracture dislocation injury might have better outcome, although this difference was not found to be statistically significant.ConclusionPercutaneous fixation of tarsometatarsal joint injuries is a relatively simple and safe method of treatment, leading to a good functional outcome, especially for Myerson type B as well as for fracture dislocation type of injuries, provided that an anatomical reduction has been achieved.Level of EvidenceLevel III, Therapeutic Study.     

Lisfranc fracture dislocation in a child

A case of Lisfranc fracture dislocation complicated by compartment syndrome is reported in a 9-year-old boy who fell from a 5 ft high wall which subsequently collapsed onto him crushing his lower limbs. The patient also sustained an undisplaced, open fracture of the contralateral tibia. The Lisfranc fracture dislocation was treated with open reduction and internal fixation using Kirschner wires (K-wires). Fasciotomy was performed to decompress the foot. The open tibia fracture was treated with wound debridement and plaster cast. The K-wires were removed at 10 weeks follow up. The patient had no complaints on examination and radiographs revealed good evidence of healing. We emphasize the importance of prompt diagnosis and treatment.     

Combined Innovative Portal Arthroscopy and Fluoroscopy-Assisted Reduction and Fixation in Subtle Injury of the Lisfranc Joint Complex: Analysis of 10 Cases

Subtle injuries of the Lisfranc joint complex are uncommon and difficult to diagnose clinically and thus are easily missed even by experienced orthopedic doctors. Misdiagnosed injuries can lead to chronic disability until eventual fusion surgery. We describe 10 cases diagnosed with subtle injury of the Lisfranc joint that were treated with combined innovative portal arthroscopy and fluoroscopy-assisted reduction and percutaneous screw fixation in an interfragmentary fashion. The distance between the first and second metatarsals (the Lisfranc distance) and that between the medial cuneiform and fifth metatarsal base (foot arch height) was measured before and after surgery. The American Orthopaedic Foot and Ankle Society function score was evaluated perioperatively. The average preoperative and postoperative Lisfranc distance was 4.38 ± 0.39 mm and 2.68 ± 0.9 mm, the foot arch height was 12.63 ± 2.75 mm and 21.80 ± 3.50 mm, and the American Orthopaedic Foot and Ankle Society score was 59.1 ± 5.69 and 86.8 ± 10.1, respectively. Of the 10 patients, 3 had excellent outcomes, 6 had good outcomes, and 1 had a fair outcome. In conclusion, we report a useful and minimally invasive surgery for acute, subacute, and even chronic subtle injury of the Lisfranc joint. The Lisfranc distance, foot arch height, and function of the foot were restored clinically, and all measurements showed statistically significant differences.     

Primary internal fixation and soft-tissue reconstruction in the treatment for an open Lisfranc fracture-dislocation

The importance of anatomical reduction for improved outcome has been recognised in the management of Lisfranc injuries. Operative fixation is indicated in case of dislocation or unstable ligamentous injury, because discongruity of the Lisfranc joint can lead to deleterious functional outcome. Screws are the recommended method of fixation of the medial en middle column, and K-wires are used for stabilisation of the unstable lateral column. Primary arthrodesis can provide advantages in pure ligamentous injury. In the management of complex open Lisfranc fractures, external fixation with K-wires can be used, but often results in a high percentage of arc deformities and functional limitations. In recent years, there is a progressive change from external to internal fixation in primary stabilisation of open fractures. This case report describes the treatment for a grade III open Lisfranc fracture-dislocation by use of primary internal fixation and soft-tissue reconstruction.

Staged reduction of neglected transscaphoid perilunate fracture dislocation: A report of 16 cases

ABSTRACT: BACKGROUND: Transscaphoid perilunate fracture dislocation is a rare injury and can be easily missed at the initial treatment. Once ignored, late reduction is not possible and needs extensive dissection. An alternative treatment such as proximal row carpectomy may be required for neglected injuries, but surgical outcome is not as good as that of an early reduction. We aim to present an alternative technique of staged reduction and fixation in patients of neglected transscaphoid perilunate dislocations and study its outcome. Material & Methods 16 cases (14 males & 2 females) with neglected transscaphoid perilunate fracture dislocation (> 3 month old) were treated with staged reduction. Mean duration between injury and surgery was 4.5 months. In first stage an external fixator was applied across the wrist and distraction was done at 1mm/day. Second surgery was done through dorsal approach and we were able to reduce all the fractures & dislocations. Herbert screws and K wires were used for fixation. RESULTS: The mean duration between two surgeries was 2.4 weeks (range 2- 4 weeks). 9 cases had excellent results, 5 had good result. Two patients developed reflex sympathetic dystrophy and had fair results. CONCLUSION: Staged reduction should be considered for neglected transscaphoid perilunate dislocations. If properly executed, a good functional pain free range of motion is the usual outcome.     

Prevalence and patterns of foot injuries following motorcycle trauma

OBJECTIVES: To determine the prevalence and patterns of foot injuries following motorcycle trauma. DESIGN: Prospective. SETTING: Yorkshire Region Trauma Units (Level 1 trauma centers with trauma research). PATIENTS: Individuals injured in motorcycle road traffic accidents between January 1993 and December 1999. OUTCOME MEASUREMENTS: Patient demographics, protective devices (helmet) use, Injury Severity Score (ISS), Glasgow Coma Scale (GCS), clinical details, therapeutic interventions, resuscitation requirements, duration of hospital stay, mortality, and type of foot injuries sustained. RESULTS: The parent population of 1239 contained 53 (4.3%) foot-injured motorcyclists (49 men) with a mean age of 31.7 years (range 18-79 years). Fifty-two were drivers and one was a rear-seat passenger. Mean ISS was 6.9 (range 4-33), significantly lower than the parent population mean of 34.98 (range 9-75) (P = 0.001). Mean GCS was 14.7 (range 13-15). The motorcyclists' injuries included 26 metatarsal fractures (49.1%), 14 talar fractures (26.4%), 7 os calcis fractures (13.2%), and 6 toe fractures (11.3%). Associated foot injuries included three partial foot amputations, four Lisfranc dislocations, three cases of foot compartment syndrome (two crush injuries with no fracture, one open fourth metatarsal fracture with associated Lisfranc dislocation). Forty-six motorcyclists had more than one foot injury. Associated injuries included 22 ankle fractures (41.5%), 15 tibial fractures (28.3%), 6 femoral fractures (11.3%), 5 pelvic ring fractures (9.4%), 23 upper limb injuries (43.4%), and 3 cases of chest trauma (5.7%). No one sustained abdominal trauma or head injury compared with the parent population. All patients required operative stabilization of foot fractures, including their associated injuries. Mean hospital stay was 10.9 days (range 1-35 days). In the parent population, there were 71 deaths (6.0%), whereas there was only 1 death (1.9%) in the foot-injured group (with fractures including open book pelvic, T6-8, unilateral open femur, tibial, ankle, and metatarsal) with an ISS 33, who died of multiorgan dysfunction syndrome. At final follow-up, all patients underwent radiologic and clinical assessment of foot injuries. Forty-three patients returned to their previous occupation and level of mobility. Ten of the more significantly injured patients had to modify their occupation from manual to sedentary-type jobs due to their foot injuries. We noted a pattern of complex ipsilateral foot and limb injury in nine patients, which we postulate was due to the actual mechanism of contact with the road surface. CONCLUSION: Motorcycle accidents continue to be a source of severe injury, especially to the foot. The most common foot injury is a metatarsal fracture; however, there must be a high index of suspicion for associated injuries. Although these injuries are associated with a low mortality rate, they require prompt assessment and treatment to limit long-term morbidity and disability. The difference in foot injury pattern and mortality between the parent population and our series, among other factors, potentially may be influenced by the actual mechanism of contact with the road surface and the modifying action of the foot during the accident.     

Lisfranc Joint Ligament Complex Reconstruction: A Promising Solution for Missed,Delayed, or Chronic Lisfranc Injury Without Arthritis

The current classifications of “Lisfranc injury” can be purely ligamentous (low-grade midfoot sprains) or involve the osseous and articular structures (high-grade Lisfranc fracture displacements). The first type is often difficult to detect. If these patients are not properly treated, long-term disability can result. The rate of missed or delayed diagnoses has ranged from 13% to 24%, primarily owing to the subtlety of the radiographic findings. This is relatively more common in cases of subtle ligamentous injury (19%). The aim of the present report was to provide a new technique for missed or delayed Lisfranc injury without degenerative local signs. The Lisfranc ligament complex reconstruction is performed with a gracilis tendon graft and is protected by temporary screw fixation. We performed this technique in 3 patients. All 3 patients obtained good results, have been able to resume their previous activities, and have stated they would undergo this type of procedure again. The minimum follow-up length was 2 years.     

Lisfranc injury and Jones fracture in sports

This article provides an update and overview of Lisfranc injury and Jones fracture in the athletic population. Sports-related Lisfranc sprains or fractures are subtle injuries that can be easily missed. Now, there is greater understanding of midfoot sprains that represent a spectrum of injury to the Lisfranc ligament complex. Most types of fifth metatarsal fractures have a favorable prognosis and can be treated conservatively. The treatment options for Jones fractures in athletes have been much debated. This article discusses issues related to anatomy, mechanism of injury, clinical presentation, imaging, and diagnosis, which are necessary to appropriately treat these injuries.     

Lisfranc injury: how frequently does it get missed? And how can we improve?

Lisfranc injuries are sometimes easily missed especially if they present in a subtle form. In this study, we have tried to measure the level of accuracy of plain radiographs in detecting this type of injury. We have selected 30 sets of foot radiographs with various diagnoses. Eighteen of them had a Lisfranc type of injury which was confirmed by operative findings or further imaging. These radiographs, together with a small diagnostic questionnaire, were presented to nine senior clinicians. We found that only 11 of the 18 cases (61%) were detected by all the readers. Eight of nine readers (90%) missed one particular case of subtle Lisfranc injury in a diabetic neuropathic foot. One case of a divergent injury was missed by five readers (56%). Another case with a coexistent Frieberg's disease was missed by three readers (33%). The mean accuracy for all injuries was 87% (95% confidence interval (CI) 84.6-89.9%). The mean accuracy level for detection of Lisfranc injury among the whole series was 92% (CI 89-95%). We think that the presence of a strong clinical index of suspicion or the presence of impaired pain sensation, further imaging is a must to avoid missing this type of injury at early presentation, and consequently the long term poor prognosis.     

Efficacy of open reduction and internal fixation with a miniplate and hollow screw in the treatment of Lisfranc injury

Purpose: To investigate efficacy of open reduction and internal fixation with the miniplate and hollow screw in the treatment of Lisfranc injury. Methods: Ten cases of Lisfranc injury treated by open reduction, miniplate and hollow screw in our hospital were retrospectively analyzed. There were 6 males and 4 females with age ranging from 25 to 45 years (mean 32 years). Among them, one case was classified as Type A, six Type B and three Type C. Injury mechanism included road traffic accidents (3 cases), fall from height (5 cases) and hit by heavy object (2 cases). All injuries were closed without cerebral trauma or other complicated injuries. The time interval between injury and operation was 6e10 days (average 6.6 days). Postoperatively, the foot function was assessed using Visual Analogue Scales (VAS) and American Orthopaedic Foot and Ankle Society (AOFAS) Scales. Healing time and complications were observed. Results: All patients were followed up for 18e24 months (average 20 months). Anatomic reduction was achieved in all patients on images. There was statistical significance between preoperative score (7.89 ± 0.34) and score at postoperative 8 weeks (0.67 ± 0.13). According to the AOFAS score, 5 cases were defined as excellent, 3 cases as good and 2 cases as fair. During follow-up, there was no wound infection or complications except for osteoarthritis in 2 cases. Healing time ranged from 3 to 6 months with an average of 3.6 months. Conclusion: Anatomical reduction of Lisfranc injury can be achieved by open reduction and internal fixation with the miniplate and hollow screw. Normal structure of Lisfranc joint is regained to a great extent; injured ligaments were also repaired. Therefore, this method offers excellent curative effect and can avoid postoperative complications and improve the patients'' quality of life.     

Chopart-Luxation – eine einfache Diagnose?

The case of an initially overlooked transligamentary Chopart dislocation following distorsion trauma of the foot is presented and the treatment and long-term course are discussed. A 55-year-old female patient sustained severe injury to the left foot after falling from a height of 4 m.. The instep was severely swollen and there was deformity with adduction of the forefoot and supination position. The peripheral pulse and sensitivity were intact. The conclusion from local radiographic investigations was that there were no signs of fracture or dislocation. The patient travelled home in pain 1 week after the accident and registered in the casualty department at our hospital. Assessment of the radiographs revealed a transligamentary Chopart dislocation with dorsolateral dislocation of the talus head, avulsed navicular fragments and a depressed fracture at the medial talus head. Treatment was initiated immediately after diagnosis with closed reduction and percutaneous K-wire fixation and 8 weeks immobilization in a lower leg plaster cast. Chopart dislocation is a rare consequence of accidental distortion trauma of the foot. Peritarsal dislocations represent approximately 15% of tarsal injuries and 1% of joint dislocations overall. Therefore, if a high energy accident has occurred, it is necessary to specifically search for dislocations and fractures. Immediate reduction reduces the risk of complications.
