Abstract
BACKGROUND For the temporary treatment of ankle fracture dislocations (AFDs), previous studies indicate higher rates of secondary loss of reduction (LOR) with splint immobilization, prompting consideration for expanding indications for external fixation (ExFix). However, these studies did not investigate the influence of fracture morphology to further improve patient selection. The aim of this study was to investigate the influence of Lauge-Hansen injury type on the LOR rate in bimalleolar or trimalleolar AFDs for temporary cast vs ExFix immobilization. METHODS In this retrospective cohort study, patients with isolated AFD cases treated at our institution from 2011 to 2020 were reviewed. Inclusion criteria required radiographs depicting initial dislocation and appropriate reduction after Cast or ExFix immobilization. Exclusion criteria encompassed concomitant injuries, open fractures, conservative management as well as surgery performed within 48 hours or at a different facility. Patients were grouped by temporary treatment (Cast or ExFix). The primary endpoint was LOR prior to definitive surgery across various Lauge-Hansen types. RESULTS The LOR rate was significantly higher in the cast group (40/152, 26.3%) compared to the ExFix group (5/191, 2.6%; P < .0001). In the cast group, LOR was associated with an increase in time to definitive surgery by a mean of 3 days (P < .002). During cast treatment, LOR was significantly more likely for pronation abduction (P = .001) and supination external rotation injuries (P < .0001), whereas no significant differences were observed for pronation external rotation (P = .006), supination adduction (P > .99), and fractures not classifiable (P > .99). CONCLUSION In cases of AFDs resulting from supination external rotation or pronation abduction trauma according to the Lauge-Hansen classification, especially in the setting of an additional posterior malleolar fracture, primary application of external fixation should be considered to reduce the risk for secondary loss of reduction.

Abstract
INTRODUCTION Valid epidemiological data about distal fibular fractures and their treatment strategies are missing. Innovative osteosynthesis techniques were introduced and improved during the past 15 years. The aim of this study was to investigate the epidemiologic development and the implementation of new treatment strategies in a nationwide register in Germany over a period of 15 years. MATERIALS AND METHODS Data of the German Federal Statistical Office from 2005 until 2019 were screened. Adults with a fracture of the distal fibula were included. Data were separated for gender, age and treatment strategy. RESULTS During the past 15 years, there was a steady annual incidence of distal fibula fractures of 74 ± 32 per 100,000 people without any significant changes (p = 0.436). 60.1% ± 0.6% of all fractures occurred in females. The annual incidence for male was nearly constant over the different age groups, whereas for female, there was a clear increase in incidence above the age of 40. Whereas 66% of fractures in between 20 and 30 years of age occurred in male, approximately 70% of fractures above the age of 60 occurred in females. The relative quantity of locking plates increased from 2% in 2005 to 34% in 2019. In 2019, only 1.02% of the patients were operated with an intramedullary nail. CONCLUSIONS Operatively treated distal fibular fractures revealed an age dependent increase in incidence in postmenopausal women compared to younger females. Regarding the treatment strategy, there was an increase in application of locking plates. The data implicate a typical fragility fracture related age and gender distribution for distal fibula fractures.

Abstract
INTRODUCTION Biomechanical studies have proved that locking plates have better primary stability besides versatility regarding fracture pattern while reducing bone contact and bridging the gap, whereas conventional nonlocking plates (plus lag screw) depend on bone-plate compression. The clinical benefit of locking plates over nonlocking plates remains unanswered, however. Therefore, this retrospective cohort study was set up to test the hypothesis that the use of locking plates for unstable ankle fractures will result in fewer re-displacements, superior bony healing, and functional and clinical outcomes better than observed in the nonlocking cohort. METHODS Bimalleolar ankle fractures (AO 44-B2) without syndesmotic injury treated with either a locking or a nonlocking plate were included. Groups were compared for complications, bone healing, secondary dislocation, progressions of osteoarthritis, and clinical outcome using patient-reported outcome measures. RESULTS Data revealed no clinical outcome differences (Olerud-Molander Ankle Score: nonlocking 88.2 ± 14.4, locking 88.8 ± 12.3, P = .69, robust two 1-sided test for equality (RTOST): P = .03; American Orthopaedic Foot and Ankle Score: nonlocking 91.2 ± 12.9, locking 91.8 ± 11.3, P = .96, RTOST: P = .04). Nevertheless, a significant postoperative progression of osteoarthritis was detected in both groups (P = .04). This was independent of implant (P = .16). Although difference was not significant, locking plates were preferred in older (P = .78) and sicker patients (P = .63) and in cases with severer osteoarthritis (P = .16), and were associated with a higher complication rate (P = .42) and secondary dislocation (nonlocking 9.4%, locking 18.2%; P = .42). Re-displacement, however, was not a compelling reason for revision. CONCLUSIONS The present study shows statistically significant equality of both types of implants. Contrary to our expectation, locking plates seemed to be associated with a higher risk for re-displacement. Overall, the use of either locking or nonlocking plates for unstable AO 44-B2 fractures is safe and successful despite significant progression of osteoarthritis.

Abstract
BACKGROUND Posterior malleolar fractures are found in almost 50% of all ankle fractures. The high clinical relevance of these joint fractures is explained by the significantly worse clinical and functional outcome. There is still a lack of unified opinion regarding the classification and treatment of these fractures. OBJECTIVE The aim of this article is to provide a systematic literature review of clinical studies that investigated posterior malleolar fractures and classified them using one of the three established classifications according to Haraguchi, Bartonicek/Rammelt, or Mason. MATERIAL AND METHODS PubMed was searched without time limits. The systematic literature search was performed according to the current criteria of Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). The methodological quality of the included studies was quantified using the modified Coleman score. RESULTS A total of 27 studies with a total of 2220 patients were included in this systematic literature review. Trimalleolar fractures showed a significantly less favorable prognosis than other ankle fractures. The quality of reduction was the most important prognostic factor for the clinical outcome. CONCLUSION None of the three classifications examined has become established in the literature. Most of the classifications are weak or should not be used with respect to a derivable treatment algorithm or a prognosis with respect to the outcome. Only the classification according to Bartonicek/Rammelt is suitable to become established in the literature and in clinical practice due to its derivable treatment algorithm.

Foot Ankle Surg 2021; 27:736-741. [PMID: 33046382 DOI: 10.1016/j.fas.2020.09.012] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2020] [Revised: 09/13/2020] [Accepted: 09/21/2020] [Indexed: 02/04/2023]
Abstract
BACKGROUND Malleolar accessory ossicles can be found in patients with chronic lateral ankle instability (CLAI). Ossicle resection combined with the modified Broström procedure is the most commonly used surgical method. However, an unrepairable gap after ossicle resection often occurs in patients with large ossicles. PURPOSE This study analysed the clinical outcomes of ossicle resection and anatomic ligament reconstruction (ALR) for CLAI with large malleolar accessory ossicles. METHODS This study was a retrospective case series. Since 2014, we have adopted ALR for patients with difficulties using the modified Broström procedure after ossicle resection. Sixteen patients with chronic ankle instability and malleolar accessory ossicles were treated with this method between December 2014 and February 2018. The average age of the patients at the time of surgery was 28.9 (range, 16-65) years. They were followed up for an average time of 26.9 (range, 12-47) months. The clinical outcomes were evaluated using the Visual Analogue Scale, Karlsson-Peterson ankle scoring system, subjective satisfaction of patients, and radiographic parameters. RESULTS All unrepairable cases occurred in patients with ossicles larger than or equal to 10 mm. The VAS score improved from 3.5 ± 1.6 preoperatively to 1.4 ± 1.0 at the final follow-up (p < 0.05), and the Karlsson-Peterson score improved significantly from 52.7 ± 15.1 to 86.4 ± 8.2 (p < 0.05). There was also an obvious change in the varus talar tilt angle (15.4 ± 2.0° vs 6.2 ± 1.6°, p < 0.05) and anterior talar displacement (14.3 ± 2.1 mm vs 6.3 ± 1.4 mm, p < 0.05). Fourteen patients (87.5%) were satisfied (excellent or good) with their clinical outcomes. CONCLUSION If modified Broström procedure is difficult to accomplish effectively after ossicle resection for chronic ankle instability with large malleolar accessory ossicles, ALR is a viable option with satisfactory clinical results.

Abstract
OBJECTIVE Stabilization of the syndesmotic complex by open reduction and internal fixation (ORIF) of the posterior malleolus, restoration of the tibial articular surface, stability of the ankle, posterior tibiofibular ligament and the incisura tibiae, reduction of the fibula into the incisura tibiae by ligamentotaxis. INDICATIONS Unstable ankle fractures (OTA/AO type 44-B3, C1.3, C2.3, C3.3) with involvement of the posterior malleolus (type II-IV according to Bartoníček and Rammelt). CONTRAINDICATIONS Critical general condition, circulatory disorders, severe soft tissue swelling (if necessary, first external fixator), percutaneous treatment the better alternative. SURGICAL TECHNIQUE Positioning in unstable lateral position, dorsolateral approach dorsally of the peroneal tendons, incision of the superficial and deep fascia, retraction of the flexor hallucis longus tendon medially, visualization of the posterior malleolus, reduction and fixation. To treat the lateral malleolus fracture, preparation of a full-thickness flap above the peroneal tendons on the fibula, treatment according to AO principles. For the treatment of the medial malleolus positioning in supine position without changing the sterile covers, medial approach for the medial malleolus, wound closure. POSTOPERATIVE MANAGEMENT Six weeks partial weight bearing (20 kg), early functional exercise, exercise of the flexor hallucis longus muscle; transition to full weight bearing after clinical and radiological follow-up after 6 weeks RESULTS: Few clinical results on open ORIF of the posterior malleolus have been published. However, most studies found that ORIF resulted in better reconstruction of the distal articular surface and the tibial incisura, better reduction of the fibula into the tibial incisura, stabilization of the distal tibiofibular joint and better clinical results, regardless of fragment size, when compared to closed reduction or untreated fragments.

Abstract
The anterolateral tibial rim with the anterior tibial tubercle (Tubercule de Tillaux-Chaput) serves as an insertion site of the anterior inferior tibiofibular ligament (AITFL). It can also be termed the anterior malleolus or fourth malleolus. Fractures of the anterolateral tibial rim typically result from an external rotation or abduction mechanism of the talus within the ankle mortise. They are frequently overlooked in plain radiographs. Computed tomography (CT) is needed for an exact visualization of the fracture anatomy and treatment planning. A total of three main types can be differentiated: (1) extra-articular avulsion fracture of the AITFL, (2) fracture of the anterolateral distal tibia with involvement of the joint and tibial incisura and (3) impaction fracture of the anterolateral tibial plafond. Surgical fixation of displaced anterolateral distal tibial fractures aims at bone-to-bone stabilization of the anterior syndesmosis, restoration of the tibial incisura for the distal fibula and joint surface. Displaced extra-articular avulsion fractures (type 1) are fixed with a suture anchor or transosseal suture. Larger fragments involving the tibial incisura and plafond (type 2) are mostly fixed with screws. Impression fractures of the anterolateral tibial plafond (type 3) necessitate elevation with restoration of the joint surface, bone grafting of the impaction zone as needed and anterior buttress plating. Only a few studies have reported the treatment results of anterolateral tibial rim fractures in adults. Conservative treatment of dislocated fragments reportedly leads to non-union and malposition of the distal fibula with incongruence of the ankle mortise requiring revision. Impaction fractures (type 3) can lead to secondary avascular necrosis of the anterolateral tibial plafond.

Abstract
BACKGROUND Ankle fractures are among the most common fractures in adults but often with unsatisfactory long-term results. In recent years several new surgical treatment approaches have been developed but little has changed regarding the aftercare. The postoperative treatment can be divided into two main components, weight bearing and mobilization. In Germany most patients are still recommended to be immobilized with partial weight bearing for 6 weeks after surgery. OBJECTIVE The aim of this review is to present the current evidence on postoperative treatment based on an extensive literature search. MATERIAL AND METHODS A total of seven prospective randomized controlled trials (RCT) compared early and delayed full weight bearing and six RCTs compared ankle mobilization with a form of immobilization. RESULTS In none of these studies did early full weight bearing lead to an increased complication rate but some studies found a shortened time before return to work and, at least in the short term, better clinical results. Immediate mobilization led to an increased complication rate in only one out of six studies. It also appeared that mobilization led to a reduced time before return to work and, in the short term, to better clinical outcomes. The comparability of the studies was limited as in most cases different clinical scores and parameters were collated. In addition, information on patient age, fracture type, bone quality, comorbidities, and the implants used was often inadequate and post-treatment regimens sometimes differed significantly. CONCLUSION The early functional therapy following surgically treated ankle fractures increased the rate of wound healing complications in only one of 13 studies, otherwise there were no significant differences in complication rates; however, early functional therapy partly shortened the time to return to work and led to better clinical results in the short term. For future studies, standardization of the parameters assessed would be important to provide clear evidence-based guidelines on follow-up treatment for specific fractures and patient populations.

Abstract
Ankle fractures with involvement of the posterior malleolus have a poor prognosis. The traditional concept of addressing the posterior fragment as the final step in the surgical reconstruction depending on the fragment size manifest in the lateral X‑ray, does not do justice to the anatomic and biomechanical relevance of the posterior malleolus. Intra-articular step-offs and fragment displacement ≥ 2 mm, impacted intercalary fragments, involvement of the fibular notch and instability of the syndesmosis, represent parameters relevant for the surgical reconstruction and the functional and radiomorphological outcome independent of fragment size. A valid assessment of these parameters can only be achieved via computed tomography (CT) including multiplanar 2D and 3D reconstruction. This is the foundation for the classification of posterior malleolar fractures according to Bartoníček et al., it forms the basis of the preoperative analysis of the fracture components and represents a decision-making tool for the indications for surgery. The individual fracture pattern guides the selection of the suitable approach or a combination of approaches and the surgical strategy. Making use of the posterior approaches enables the surgeon to have a direct view of the fracture components of the posterior malleolus as a precondition for an anatomic reduction. This central surgical step is frequently done as the first measure of the surgical reconstruction of the ankle joint. Furthermore, direct reduction and posterior stabilization is more accurate and stable than indirect reduction from an anterior approach with indirect fixation using lag screws. An additional temporary transfixation of the tibiofibular syndesmosis is often dispensable.

Abstract
"Chronic syndesmotic injury covers a broad range of symptoms and pathologies. Anterolateral ankle impingement without instability is treated by arthroscopic debridement. Subacute, unstable, syndesmotic injuries are treated by arthroscopic or open debridement followed by secondary stabilization using suture button device or permanent screw placement. Chronic syndesmotic instability is treated by a near-anatomic ligamentoplasty supplemented by screw fixation. In case of poor bone stock, failed ligament reconstruction, or comorbidities, tibiofibular fusion with bone grafting is preferred. Malleolar malunions and particularly anterior or posterior syndesmotic avulsions must be corrected in order to achieve a stable and congruent ankle mortise."
