Abstract
PURPOSE Although arthroscopic repair of the deltoid ligament is becoming a popular procedure, no studies have assessed which bundles of the deltoid ligament can be reached by anterior ankle arthroscopy. This study aimed to assess the feasibility of the arthroscopic repair of the deep layer of the deltoid ligament. In addition, it aimed to correlate which fascicle of the superficial layer of the deltoid ligament corresponds to the deep fascicle visualised by arthroscopy. METHODS Arthroscopy was performed in 12 fresh frozen ankles by two foot and ankle surgeons. With the arthroscope introduced through the anterolateral portal, the medial compartment and the deltoid ligament were explored in ankle dorsiflexion without distraction. Using a suture passer introduced percutaneously, the most posterior fibres of the deep deltoid ligament visualised by anterior arthroscopy were tagged. Then, the ankles were dissected to identify the deep and superficial bundles of the deltoid ligament tagged with a suture. RESULTS In all specimens (100%), the intermediate part of the tibiotalar fascicle, corresponding to the fibres originating from the anterior colliculus, was tagged with a suture. The posterior part of the tibiotalar fascicle was never tagged with a suture. In all specimens, the intermediate part of the tibiotalar fascicle grasped by the suture correlated with the tibiospring fascicle of the superficial layer. CONCLUSIONS The current study demonstrates the feasibility of the arthroscopic repair of the deep fascicle of the deltoid ligament. By performing anterior arthroscopy, it is possible to visualise and repair the intermediate part of the tibiotalar fascicle (deep layer of the deltoid ligament). These fibres correspond to the tibiospring fascicle of the superficial layer. The clinical relevance of the current study is that the arthroscopic repair of the deep layer of the deltoid ligament is feasible through anterior ankle arthroscopy. LEVEL OF EVIDENCE Not applicable.

Abstract
BACKGROUND Weber B fractures with concomitant deltoid ligament injury have traditionally been operated with open reduction and internal fixation of the fibular fracture. More recently, clinical studies have suggested that some fractures have concomitant partial deltoid ligament injury with the deep posterior tibiotalar ligament intact (SER4a), allowing for nonoperative treatment in this subgroup. This study explores whether plate fixation of the fibula improves ankle stability in an SER4a injury model. And if so, does it restore native ankle stability? METHODS Fifteen cadaver ankle specimens were tested in 3 states using an industrial robot: intact joint, SER4a models without plate fixation of the fibula, and SER4a models with plate fixation of the fibula. The robot measured ankle stability in lateral translation, valgus, and internal and external rotation in 3 talocrural joint positions: 10 degrees dorsiflexion, neutral, and 20 degrees plantar flexion. Furthermore, fluoroscopic mortise view radiographs were taken to measure isolated talar shift and talar tilt. RESULTS The talar shift and tilt tests showed no differences between the SER4a injury model with and without fibular plate fixation at neutral ankle position with a mean difference of -0.16 mm (95% CI -0.33 to 0.01 mm, P = .071) for talar shift and -0.15 degrees (95% CI -0.01 to 0.30 degrees, P = .068) for talar tilt. However, plate fixation increased external rotation stability, with mean improvements ranging from -7.43 to -9.52 degrees (P < .001 for all comparisons), but did not restore intact ankle stability. For internal rotation, plate fixation resulted in minor differences. CONCLUSION The results of this suggest that plate fixation of the fibular fracture primarily improves external rotation stability but does not substantially improve lateral translation, valgus, or internal rotation stability in SER4a injury models. In this robotic cadaver model, fibular plate fixation did not fully restore intact ankle stability after simulated SER4a injury. CLINICAL RELEVANCE This study offers insights into the effects of fibular plate fixation on Weber B/SER4a injury models and may assist informed decisions when selecting treatments for these types of fractures.

Abstract
The deltoid ligament is vitally important in the stability of the ankle and preventing excessive medial ankle movement. Historically, the impact of medial ankle instability has not been well understood in the setting of chronic ankle instability. A retrospective review of 226 patients treated for ankle instability between 2017 and 2022 identified 40 patients who required both medial and lateral repair. Decision for medial deltoid repair was based upon patient presentation, MRI findings, intraoperative fluoroscopy and final confirmation via arthroscopic positive "drive-through sign". Preoperative and postoperative American Orthopedic Foot and Ankle Society (AOFAS) hindfoot-ankle scores, Patient-Recorded Outcomes Measurement Information System (PROMIS) scores, and Karlsson-Peterson Ankle Function (K&P) scores were obtained and compared. There were statistically significant improvements found in all 3 scoring systems at a mean follow-up time of 11.7 months postoperatively. In the setting of chronic ankle instability, consideration should be given to the evaluation and potential repair of the deltoid ligament in order to provide sufficient stability to the medial ankle.

Abstract
RATIONALE Medial malleolus injuries mainly comprise of fractures and deltoid ligament ruptures. Medial malleolus fractures, as a kind of common ankle fractures, could occur separately or be accompanied by lateral and posterior malleolus fractures. It is generally agreed that medial malleolus fracture and deltoid ligament rupture could not occur simultaneously. PATIENT CONCERNS In our study, we report a case of 36 year-old man diagnosed with trimalleolar fracture accompanying ankle dislocation initially. The patient was admitted to our hospital due to traffic accident. DIAGNOSIS The patient was diagnosed with trimalleolar fracture accompanying ankle dislocation initially. We missed the diagnosis of accompanied deltoid ligament due to the arthralgia of medial ankle and the widened medial articular space in X-ray after operation. INTERVENTION As we missed the diagnosis of accompanied deltoid ligament, we only selected open reduction and internal fixation for trimalleolar fracture at first. After we realized the existence of deltoid ligament rupture, the patient refuse further diagnosis and treatment in our hospital. OUTCOMES During the rehabilitation exercise, the patient had medial arthralgia in his right ankle. He complained it and refuse further diagnosis and treatment in our hospital. LESSONS The newfound injury pattern, medial malleolus fracture accompanying deltoid ligament rupture, has not been reported in previous studies. The injury pattern needs further researches to explore the mechanism and it should be taken seriously in clinical practice.

Abstract
BACKGROUND Magnetic resonance imaging (MRI) is effective in diagnosing deltoid ligament (DL) injury but its sensitivity in chronic cases is low. Additional diagnostic signs are required to reduce the risk of a false negative diagnosis. PURPOSE To evaluate the added diagnostic value of bone marrow edema at the ligament insertion (BMELI) of DL to the MRI assessment of chronic DL injury. MATERIAL AND METHODS One hundred patients who consecutively came to our institution between November 2018 and December 2021 and underwent arthroscopic surgery for chronic ankle instability (CAI) were enrolled in the present study. Preoperative MR images were retrospectively reviewed by two orthopedic surgeons to evaluate the sensitivity, specificity and interobserver reliability of three MRI signs in diagnosing chronic DL injury, namely, abnormal ligamentous morphological characteristics (ALMC), BMELI and medial clear space (MCS). RESULTS Taking arthroscopy as the reference standard, there were 34 patients with and 66 without DL injury. ALMC had 64.71% (22/34; 46.47-79.70) sensitivity and 83.33% (55/66; 71.71-91.00) specificity, BMELI had 70.59% (24/34; 52.33-84.29) sensitivity and 95.45% (63/66; 86.44-98.82) specificity and MCS had 26.47% (9/34; 13.51-44.65) sensitivity and 92.42% (61/66; 82.50-97.18) specificity. Compared with ALMC, BMELI had similar efficacy in superficial cases (P = 0.06) and greater efficacy in deep cases (P = 0.04). All three signs showed good interobserver agreement (kappa values all above 0.7). CONCLUSION BMELI can reliably indicate concomitant injury to the DL in CAI patients. Using BMELI as a sign of chronic DL injury when ALMC is unclear may reduce the risk of a false negative diagnosis.

Abstract
Background A combined reconstruction of chronic deltoid and spring ligament insufficiency is uncommon. Our study aims to share our experience in treating post-traumatic, chronic deltoid, and spring ligament insufficiency using the "quadrangular construct" technique. Material and methods Five patients who had post-traumatic combined deltoid and spring ligament insufficiency were included in the study. All patients reported a "giving-way" sensation. Preoperatively, each patient underwent weight-bearing radiographs of the ankle and foot. The talo-first metatarsal angle and hindfoot alignment angle were noted. The superficial deltoid ligament was repaired using a suture anchor augmented with Internal BraceTM (Arthrex, Naples, USA) FiberTape® to form a quadrangular construct that anatomically mimics various components of the deltoid-spring ligament complex. Due to the associated excessive heel valgus, three patients also underwent medial displacement calcaneum osteotomy. Additionally, one patient required lateral ligament repair, and another patient required syndesmotic stabilization. The American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score was used to evaluate preoperative and postoperative ankle function. Results All five patients were followed up for a mean of 20 months (range: 12-24 months). The mean preoperative talo-first metatarsal angle improved from 8.46 degrees to 4.84 degrees. The preoperative mean hindfoot alignment angle was reduced from 10.9 to 5.76 degrees postoperatively. One patient had irritation due to the anchor, which needed removal after one year. Postoperatively, no patients re-experienced the feeling of "giving way". The AOFAS scores postoperatively showed two patients as excellent, two as good, and one as fair. All the patients returned to their pre-injury work. Conclusion We have developed a technique for combined deltoid and spring ligament reconstruction using a quadrangular construct. This technique helps to restore anatomical stability, is safe, easily reproducible, and has shown positive short-term results in follow-up. The level of evidence is one of the methods used to categorize the quality and reliability of research, and our study falls under the category of level IV evidence.

Abstract
Background Deltoid ligament reconstruction of the ankle can be considered when the ruptured ligament is insufficient for direct repair. Purpose To compare the safety of talar tunnels oriented toward 4 different anatomic landmarks on the lateral malleolus during reconstruction of the deep layer of the deltoid ligament (DDL). Study Design Descriptive laboratory study. Methods A total of 30 computed tomography scans of the ankle joint in healthy adults were collected to generate 3-dimensional models. Virtual talar tunnels with a diameter of 5 mm and with different lengths (20.0, 25.0, and 30.0 mm) were created from the talar insertion of the DDL and were oriented toward the talar neck as well as the most anterior, the most distal, and the most posterior points of the distal fibula. The minimal safe distance (MSD) of a drilling route was calculated for the tunnels, and the safe distance from the end of the tunnel to the bone surface was measured for each tunnel. The nonpaired Student t test was used to detect differences among the safe distances of the 4 different bone tunnels. Results For the 20.0-mm tunnels, the safe distance of the tunnel oriented toward the talar neck (5.90 ± 1.16 mm) did not meet the MSD (6.0 mm). For the 25.0-mm tunnels, the safe distances of the tunnels oriented toward the talar neck (4.53 ± 1.13 mm) and the anterior point of the fibula (5.91 ± 1.52 mm) did not meet the MSD (6.9 mm). Conclusion Tunnels that were 5 mm in diameter and 20.0 and 25.0 mm in length, oriented toward the most distal or most posterior point of the distal fibula, were safe for DDL reconstruction. Clinical Relevance Knowledge of safe talar tunnel placement is important, especially to avoid bone surface penetration during DDL reconstruction.

Abstract
Aims Treatment of Weber B ankle fractures that are stable on weightbearing radiographs but unstable on concomitant stress tests (classified SER4a) is controversial. Recent studies indicate that these fractures should be treated nonoperatively, but no studies have compared alternative nonoperative options. This study aims to evaluate patient-reported outcomes and the safety of fracture treatment using functional orthosis versus cast immobilization. Methods A total of 110 patients with Weber B/SER4a ankle fractures will be randomized (1:1 ratio) to receive six weeks of functional orthosis treatment or cast immobilization with a two-year follow-up. The primary outcome is patient-reported ankle function and symptoms measured by the Manchester-Oxford Foot and Ankle Questionnaire (MOxFQ); secondary outcomes include Olerud-Molander Ankle Score, radiological evaluation of ankle congruence in weightbearing and gravity stress tests, and rates of treatment-related adverse events. The Regional Committee for Medical and Health Research (approval number 277693) has granted ethical approval, and the study is funded by South-Eastern Norway Regional Health Authority (grant number 2023014). Discussion Randomized controlled trials are needed to evaluate alternative nonoperative treatment options for Weber B/SER4a ankle fractures, as current clinical guidelines are based on biomechanical reasoning. The findings will be shared through publication in peer-reviewed journals and presentations at conferences.

Abstract
BACKGROUND The importance of the deltoid ligament in the congruency and coupling of the tibiotalar joint is well known. The current trend is to repair it in cases of acute injuries in the context of ankle fractures; however, there is limited information on how it should be reconstructed. The objective of this study was to compare different deltoid ligament repair types in an ankle fracture cadaveric model. METHODS Sixteen cadaveric foot-ankle-distal tibia specimens were used. All samples were prepared as a supination external rotation ankle fracture model. Axial load and cyclic axial rotations were applied on every specimen using a specifically designed frame. This test was performed without deltoid injury, with deltoid injury, and after repair. The reconstruction was performed in 4 different ways (anterior, posterior, middle, and combined). Medial clear space (MCS) was measured for each condition on simulated weightbearing (WB) and gravity stress (GS) radiographs. Reflective markers were used in tibia and talus, registering the kinematics through a motion analysis system to record the tibiotalar uncoupling. RESULTS After deltoid damage, in all cases the MCS increased significantly on GS radiographs, but there was no increase in the MCS on WB radiographs. After repair, in all cases, the MCS was normalized. Kinematically, after deltoid damage, the tibiotalar uncoupling increased significantly. All isolated repairs achieved a similar tibiotalar uncoupling value as its baseline condition. The combined repair resulted in a significant decrease in tibiotalar uncoupling. CONCLUSION Our results show that deltoid repair recovers the tibiotalar coupling mechanism in an ankle fracture model. Isolated deltoid repairs recovered baseline MCS and tibiotalar uncoupling values. Combined repairs may lead to overconstraint, which could lead to postoperative stiffness. Clinical studies are needed to prove these results and show clinically improved outcomes. CLINICAL RELEVANCE This study helps in finding the optimum deltoid repair to use in an acute trauma setting.

Abstract
BACKGROUND Conventionally, transsyndesmotic fibula fractures with concomitant signs of deltoid ligament injury have been considered unstable and thus treated operatively. Recent studies have indicated that partial deltoid ligament rupture is common and may allow for nonoperative treatment of stress-unstable ankles if normal tibiotalar alignment is obtained in the weightbearing position. Biomechanical support for this principle is scarce. The purpose of this study was to evaluate the biomechanical effects of gradually increasing deltoid ligament injury in transsyndesmotic fibula fractures. METHODS Fifteen cadaveric ankle specimens were tested using an industrial robot. All specimens were tested in 4 states: native, SER2, SER4a, and SER4b models. Ankle stability was measured in lateral translation, valgus, and internal and external rotation stress in 3 talocrural joint positions: 20 degrees plantarflexion, neutral, and 10 degrees dorsiflexion. Talar shift and talar valgus tilt in the talocrural joint was measured using fluoroscopy. RESULTS In most tests, SER2 and SER4a models resulted in a small instability increase compared to native joints and thus were deemed stable according to our predefined margins. However, SER4a models were unstable when tested in the plantarflexed position and for external rotation in all positions. In contrast, SER4b models had large-magnitude instability in all directions and all tested positions and were thus deemed unstable. CONCLUSION This study demonstrated substantial increases in instability between the SER4a and SER4b states. This controlled cadaveric simulation suggests a significant ankle-stabilizing role of the deep posterior deltoid after oblique transsyndesmotic fibular fracture and transection of the superficial and anterior deep deltoid ligaments. CLINICAL RELEVANCE The study provides new insights into how the heterogenicity of deltoid ligament injuries can affect the natural stability of the ankle after Weber B fractures. These findings may be useful in developing more targeted and better treatment strategies.

Abstract
Pure dislocation of the ankle is an extremely rare injury accounting for only 0.065% of all ankle injuries and 0.46% of all ankle dislocations. The mechanism of the injury generally consists of high-energy trauma which is associated with a combination of plantar flexion and inversion or eversion of the foot. We present a case of a 22-year-old male patient who sustained a closed pure ankle dislocation after a fall from a small height. He was treated conservatively with closed reduction and circumferential cast immobilization for six weeks, followed by a functional rehabilitation program. The patient presented to the emergency department with an acutely painful and deformed right ankle after falling from a height of 1 m (stairs). Radiographs showed a posteromedial ankle dislocation without fracture. Urgent closed reduction of the dislocation was performed and a posterior below-knee back slab was applied to immobilize the ankle. Dorsalis pedis and posterior tibial arteries were intact. Check X-rays confirmed proper reduction of the ankle joint. Post reduction computed tomography (CT) scan did not show any associated fractures. Magnetic resonance imaging (MRI) revealed a multiligamentous ankle injury and a small osteochondral lesion of the anteromedial talar dome. The back slab was changed to a below-knee circular cast two weeks later, as soon as the soft tissue swelling subsided. The cast was removed at the six-week follow-up and physiotherapy was initiated in order to gain functional rehabilitation and improve the range of motion. At the final follow-up (12 months), the ankle range of motion (ROM) was the same as the pre-injury status and the patient was able to return to his work. Pure ankle dislocation is a rare injury. A satisfactory outcome can be expected, provided that the appropriate conservative treatment followed by a strict rehabilitation protocol is applied.

Abstract
BACKGROUND Deltoid ligament injuries occur in isolation as well as with ankle fractures and other ligament injuries. Both operative treatment and nonoperative treatment are used, but debate on optimal treatment continues. Likewise, the best method of surgical repair of the deltoid ligament remains unclear. PURPOSE To determine the biomechanical role of native anterior and posterior components of the deltoid ligament in ankle stability and to determine the efficacy of simple suture versus augmented repair. STUDY DESIGN Controlled laboratory study. METHODS Ten cadaveric ankles (mean age, 51 years; age range, 34-64 years; all male specimens) were mounted on a 6 degrees of freedom robotic arm. Each specimen underwent biomechanical testing in 8 states: (1) intact, (2) anterior deltoid cut, (3) anterior repair, (4) tibiocalcaneal augmentation, (5) deep anterior tibiotalar augmentation, (6) posterior deltoid cut, (7) posterior repair, and (8) complete deltoid cut. Testing consisted of anterior drawer, eversion, and external rotation (ER), each performed at neutral and 25° of plantarflexion. A 1-factor, random-intercepts, linear mixed-effect model was created, and all pairwise comparisons were made between testing states. RESULTS Cutting the anterior deltoid introduced ER (+2.1°; P = .009) and eversion laxity (+6.2° of eversion; P < .001) at 25 degrees of plantarflexion. Anterior deltoid repair restored native ER but not eversion. Tibiocalcaneal augmentation reduced eversion laxity, but tibiotalar augmentation provided no additional benefit. The posterior deltoid tear showed no increase in laxity. Complete tear introduced significant anterior translation, ER, and eversion laxity (+7.6 mm of anterior translation, +13.8° ER and +33.6° of eversion; P < .001). CONCLUSION A complete deltoid tear caused severe instability of the ankle joint. Augmented anterior repair was sufficient to stabilize the complete tear, and no additional benefit was provided by posterior repair. For isolated anterior tear, repair with tibiocalcaneal augmentation was the optimal treatment. CLINICAL RELEVANCE Deltoid repair with augmentation may reduce or avoid the need for prolonged postoperative immobilization and encourage accelerated rehabilitation, preventing stiffness and promoting earlier return to preinjury activity.

Abstract
To properly diagnose and treat injuries to the ankle or foot, the physician must have good anatomical knowledge of the ligaments involved. The bundles can be distinguished and identified by ultrasound examination of the medial aspect, but this may be a challenging task. In the present illustrated study, we discuss how a detailed ultrasound examination can be made of the different ligaments within the medial aspect of the ankle and foot.

Abstract
BACKGROUND The purpose of this study was (1) to evaluate the biomechanical properties of the different bundles of the deltoid ligament in various ankle positions in a cohort of healthy adult volunteers; (2) describe the impact of demographic and hindfoot morphology characteristics on their stiffness; (3) to assess the reliability and reproducibility of these measurements. METHODS Deltoid ligament complex of both ankles were assessed by shear-wave elastography (SWE) in 20 healthy patients resting on hinge support. The propagation shear-wave speed (SWS) in ligaments was measured, which is related to the tissue's elastic modulus. The following ligaments were analyzed in a neutral position and then in varus, valgus, dorsal, and plantar flexions: tibionavicular ligament (TNL), tibiocalcaneal ligament (TCL), the superficial posterior tibiotalar ligament (SPTL), the anterior tibiotalar ligament (ATTL), and the deep posterior tibiotalar ligament (DPTTL). RESULTS The mean SWS increased between neutral and 20 degrees valgus position for TCL (4.08 ± 0.78 m/s vs 5.56 ± 0.62 m/s, respectively; P < .0001) and for DPTTL (2.58 ± 0.52 m/s vs 3.59 ± 0.87 m/s, respectively; P < .0001). The mean SWS increased between neutral and 30 degrees plantarflexion for ATTL (2.11 ± 0.44 m/s vs 3.1 ± 0.5 m/s, respectively; P < .0001) and TNL (2.96 ± 0.66 m/s vs 4.99 ± 0.69 m/s, respectively; P < .0001). The mean SWS increased between neutral and 20 degrees dorsal flexion for SPTL (4.2 ± 1 m/s vs 5.45 ± 0.65 m/s, respectively; P < .0001).Women had less DPTTL SWS than men in the neutral position (2.37 ± 0.35 m/s vs 2.71 ± 0.49 m/s, respectively; P = .007). Other demographics had no impact on the SWS value of other ligaments. All inter- and intraobserver agreements were good to excellent. CONCLUSION This study presents a reliable and reproducible SWE measurement protocol to describe the physiological function of all bundles of the medial collateral ligament in healthy adults. CLINICAL RELEVANCE This examination technique can be available to orthopaedic surgeons, allowing reliable and reproducible monitoring of the SWS of the various ligaments constituting the medial collateral plane. The biomechanical values described in this study may give insight into in what position medial ankle ligament reconstruction should be tensioned.

Abstract
BACKGROUND The deltoid ligament (DL) is an important stabilizer of the ankle. DL injury of varying severity can occur alone or with syndesmotic injury and fibular fracture. Limited diagnostic tools are available to assess DL injury quantitatively. PURPOSE To establish an arthroscopic quantitative assessment of DL injury and to compare its performance with that of external rotation stress (ERS) and gravity stress (GS) radiography. STUDY DESIGN Controlled laboratory study. METHODS In total, 24 cadaveric lower extremities were divided into 4 groups: group 1 consisted of intact DL, group 2 of superficial DL disruption, group 3 of deep DL disruption, and group 4 of complete DL (superficial and deep) disruption. All specimens underwent sequential sectioning of syndesmotic ligaments, and medial clear space (MCS) was measured with ankle arthroscopy, ERS radiography, and GS radiography at different stages of syndesmotic sectioning. RESULTS For noninjured deltoid (group 1) and injured deltoid (groups 2-4), area under the receiver operating characteristic curve (AUC) of measurement of MCS was 0.939 for arthroscopy, 0.932 for ERS radiography, and 0.874 for GS radiography, with a significant difference between arthroscopy and GS radiography (P = .014). For incomplete deltoid injury (groups 1-3) and complete deltoid injury (group 4), the AUC of MCS was 0.811 for arthroscopy, 0.656 for ERS radiography, and 0.721 for GS radiography, with a significant difference between arthroscopy and ERS radiography (P < .001) and between arthroscopy and GS radiography (P = .035). For all stages of syndesmotic sectioning, cutoff values of arthroscopic MCS with intact fibula were ≤2.5 mm for intact DL, between 2.5 and 3.5 mm for partial DL injury (superficial or deep), and ≥3.5 mm for complete DL injury. Arthroscopy was unable to detect a difference between superficial deltoid injury (group 2) and deep deltoid injury (group 3) in partial DL injury, with a measured MCS between 2.5 and 3.5 mm. The intraclass correlation coefficient of interrater reliability was 0.975 for arthroscopy, 0.917 for ERS radiography, and 0.811 for GS radiography. CONCLUSION Arthroscopic MCS measurement can differentiate intact DL, partial DL injury, and complete DL injury. Compared with ERS and GS radiography, arthroscopic MCS measurement has greater accuracy with excellent interrater reliability. CLINICAL RELEVANCE For patients with suspected DL injury, arthroscopic MCS is useful for determining deltoid lesion severity based on defined cutoff values for consideration in preoperative planning to improve surgical outcomes.

Abstract
BACKGROUND Internal malleolus fractures and postoperative functional limitations are serious complications of deltoid ligament repair, reconstruction, while studies on conducting beak. Anatomical structure classification of medial malleolus at home and abroad is reported rarely. Hence, this morphological study is mainly designed to investigate the anatomical morphological classification and clinical significance of medial malleolus based on computed tomography (CT) three-dimensional reconstruction. MATERIALS AND METHODS From October 2018 to January 2021, 373 patients who underwent CT examination of malleolus medialis joint in the Jiang'an Hospital of Traditional Chinese Medicine were observed. The medial malleolus was observed and classified; then, geometric parameters were measured according to different medial malleolus types. RESULTS According to the results of 373 cases, medial malleolus can be divided into four types: omega type (66%), radical sign type (16%), inverted triangle type (14%), and wave type (4%). CONCLUSIONS There are four main shapes: omega, inverted triangle, radical sign, and wave in the medial malleolus of all normal ankles. The measurement of medial malleolus parameters according to medial malleolus in different shapes was of importance to guide smooth operation of medial malleolus fixation and deltoid ligament reconstruction and epidemiological.

Abstract
BACKGROUND Double hindfoot arthrodesis is a reliable treatment option in lower extremity deformity and arthritis. Single (medial) and 2-incision techniques have been described. The purpose of this study was to evaluate the extent of cartilage debrided in each approach and to evaluate the competency of the deltoid ligament. METHODS Eight matched pairs of cadaveric specimens were acquired. One limb from each pair was randomly assigned to the single medial incision and the other to the 2-incision technique. Stress radiographs were obtained prior to dissection to evaluate for valgus tibiotalar tilt. The talonavicular and subtalar articular surfaces were denuded of cartilage and the joints disarticulated. The percentage of cartilage debrided was determined using ImageJ software. Postoperative tibiotalar tilt was measured with a technique and threshold previously described by our group. The intraclass correlation coefficient was calculated to determine inter- and intraobserver reliability. RESULTS The single medial incision demonstrated significantly less cartilage denuded than the 2-incision technique at the talar head (61.1% ± 20.4% vs 88.1% ± 6.1%, P < .001), and the posterior facets of the talus (53.5% ± 7.6% vs 73.6% ± 7.0%, P < .001) and calcaneus (55.3% ± 16.5% vs 81.0% ± 7.4%, P = .001). Overall, 75% of specimens that underwent a single medial incision approach demonstrated increased valgus tibiotalar tilt postdissection, whereas none that underwent the 2-incision technique developed increased tibiotalar tilt (P < .01). The average tibiotalar tilt among these specimens was 4.6 ± 1.3 degrees (range 2.5-5.7 degrees). For all measurements, the intraclass correlation coefficient was greater than 0.8. CONCLUSION The posterior facet of the subtalar joint and talar head are at risk of subtotal debridement, as well as increased tibiotalar tilt with the single medial incision technique. Adequate debridement may require greater soft tissue dissection, possibly at the expense of medial ankle stability. LEVEL OF EVIDENCE Level III, retrospective cohort study.

Abstract
BACKGROUND Rotational ankle instability (RAI) is associated with the faster onset of severe ankle osteoarthritis via dysfunction of the anterior talofibular ligament, calcaneofibular ligament, and deltoid ligament. No specific clinical examination is available for RAI, and diagnostic imaging has limitations in evaluating ligament degradation. This study investigated the deltoid ligament degeneration using Hounsfield unit (HU) values on computed tomography (CT) images. METHODS Patients were enrolled in this retrospective analysis if they had undergone magnetic resonance imaging (MRI) and CT scans of the ankle. The chronic ankle instability (CAI) group comprised 20 ankles with CAI (9 men, 11 women; mean age, 28.7 years) and the control group comprised 28 ankles (16 men, 12 women, mean age, 41.3 years). The average HU values of the deep posterior tibiotalar ligament (dPTL) that constitutes the deltoid ligament were measured on coronal CT images, and MRI results were used as a reference. All patients were subdivided based on the MRI findings of dPTL injury such as fascicular disruption, irregularity, and the loss of striation. RESULTS A strong negative correlation was identified between age and HU values for all patients (Spearman ρ = -0.63; P < .001). The mean HU values of the dPTL for participants aged <60 years were 81.0 HU for the control group (21 ankles) and 69.5 HU for the CAI group (P = .0075). No significant differences in the HU values were observed for the dPTL among the MRI subgroups. CONCLUSION In addition to the conventional imaging examination such as stress radiographs and MRI, HU measurements of CT images could be useful for quantitatively and noninvasively evaluating degenerative changes in the deltoid ligament for CAI patients to assist the diagnosis of RAI.

Abstract
Ankle fractures are the fourth most common fracture requiring surgical management. The deltoid ligament is a primary ankle stabilizer against valgus forces. It is frequently ruptured in ankle fractures; however, there is currently no consensus regarding repair. A systematic database search was conducted with Medline, PubMed, and Embase for relevant studies discussing patients with ankle fractures involving deltoid ligament rupture and repair. Screening, quality assessment, and data extraction were performed independently and in duplicate. Data extracted included pain, range of motion (ROM), function, medial clear space (MCS), syndesmotic malreduction, and complications. After screening, 9 eligible studies from 1990 to 2018 were included (N = 508). Compared to nonrepair groups, deltoid ligament repair patients had lower syndesmotic malreduction rates (0%-9% vs 20%-35%, p ≤ .05), fewer implant removals (5.8% vs 41% p ≤ .05), and longer operating time by 16-20 minutes (p ≤ .05). There was no significant difference for pain, function, ROM, MCS, and complication rate (p ≤ .05). In conclusion, deltoid ligament repair offers lower syndesmotic malreduction rates and reduced re-operation rates for hardware removal in comparison to trans-syndesmotic screws. Repair groups demonstrated equivalent or better outcomes for pain, function, ROM, MCS, and complication rates. Other newer syndesmotic fixation methods such as suture-button fixation require further evaluation when compared to the outcomes of deltoid ligament repair. A randomized control trial is required to further examine the outcomes of ankle fracture patients who undergo deltoid ligament repair versus trans-syndesmotic screw fixation.

Abstract
This study retrospectively evaluated patients with ankle fracture to compare the prognosis between patients who had primary repair of the superficial deltoid ligament and those who did not. A total of 71 patients with ankle fracture and fracture-dislocation combined with deltoid ligament injury were divided into 2 groups: repair of superficial layer group (33 cases) and nonrepair group (38 cases). For the repair group, patients first underwent open reduction and internal fixation of the lateral malleolus and received a stress test. If the syndesmosis was widened, it would undergo fixation of the syndesmosis with screws. If instability of the ankle joint was observed, patients might further undergo repair of the superficial deltoid ligament. Ultimately, postoperative functions were evaluated using the Philips and Schwartz scale. All patients achieved bony union without significant pain. In the repair group, plantar and dorsi flexions were 2.5 ± 4.2° (range 0 to 10) and 7 ± 7.1° (range 0 to 20) less than the normal side, respectively. In the nonrepair group, the plantar and dorsi flexions were 2.8 ± 4.6° (range 0 to 10) and 6.6 ± 5.9° (range 0 to 20) less than the normal side. Meanwhile, the Philips and Schwartz scores of the repair and nonrepair groups were 92.5 ± 4.4 (range 80 to 100) and 93.4 ± 3.8 (range 85 to 100), respectively. But the difference of prognosis between the 2 groups was not statistically significant. In conclusion, for ankle joint fracture combined with deltoid ligament injury, routinely exploring or repairing the deltoid ligament was not recommended, but repair of the deltoid ligament increased stability of the ankle joint in the early postoperative stage.

Abstract
Overcompression of the ankle syndesmosis was once thought to be improbable. Recent studies using computerized tomography (CT) however, have demonstarted otherwise; raising pertinent questions regarding the factors associated with and consequences of syndesmotic overcompression. The purpose of the present study was to directly compare different magnitudes of applied clamp force on the coronal reduction of ankle syndesmosis. Eight through-the-knee cadaveric specimens were obtained. Fiducial cannulated screws were placed in the tibia and fibula to standardize placement of the reduction clamp's tines. CT scans were obtained as baseline controls, followed by destabilization of the syndesmosis. Reductions were then performed using a clamp equipped with an inline load cell, and objective forces (60, 80, 100, 120, 140, and 160 N) applied sequentially to each of the specimens. The syndesmosis was fixed with a single quadricortical screw, and CT were scans repeated. Applied clamp forces of 60 and 80 N resulted in lateral fibular displacement and undercompression (42.9% and 57.1%, respectively), whereas forces of 140 and 160 N resulted in medial fibular displacement (p = .011 and p = .001) and overcompression (100%). The smallest mediolateral displacements were observed with 100 and 120 N, respectively. Malreduction assessment with CT was superior to traditional radiographs [r(54) = 0.22; 95% confidence interval -0.04 to 0.45; p = .101]. In our cadaveric model, an applied clamp force of 100 N most effectively mitigated iatrogenic coronal syndesmotic malreduction from under- or overcompression. Although additional research is warranted, based on the data, inherent variabilities in the applied clamp force by surgeons appear to contribute to the unacceptably high coronal syndesmotic malreduction rate.

Abstract
Ankle fractures are among the most common injuries treated by orthopaedic traumatologists. These fractures range from stable, simple injuries to complex, multi-planar unstable ones. Osseo-ligamentous structures play a paramount role in maintaining the stability of the ankle joint. The deltoid ligament is among the most important ankle static stabilizers. Rupture of this ligament along with a lateral malleolar fracture is considered by many as an unstable type of injury and usually requires surgical treatment (bi-malleolar equivalent). Left untreated, it may lead to chronic pain, loss of function and secondary arthritis. Due to lack of high-quality evidence, there are no welldefined, well-accepted criteria for the diagnosis and treatment for treating this type of injury.

Abstract
BACKGROUND The optimal method for the determination of ankle stability remains controversial in rotational ankle fractures without medial bony injury. QUESTIONS/PURPOSES The purposes of this study were to (1) evaluate whether posterior malleolar (PM) fracture displacement is associated with deltoid ligament injury in supination-external rotation (SER) ankle fractures and (2) compare the diagnostic accuracy of PM displacement and magnetic resonance imaging (MRI) evaluation of the deep deltoid ligament in identifying fractures with deltoid ligament incompetence. METHODS Patients with rotational bimalleolar injuries containing lateral malleolar and PM fractures without bony medial injury were included. After operative lateral and PM fixation, an external rotation stress test was performed to evaluate deltoid ligament stability. Operative dictations were reviewed to confirm injury pattern, stability on stress test, and visual inspection of the deltoid ligament. Maximum PM displacement was assessed on lateral X-ray. Pre-operative MRI of the ankle was performed following closed reduction and splinting. RESULTS The final cohort consisted of 13 trimalleolar equivalent fractures (torn deltoid ligament) and 20 bimalleolar fractures (medial malleolus and deltoid ligament intact). Average PM displacement was significantly higher for SER trimalleolar equivalent patterns when measured on lateral X-ray. The sensitivity of detecting trimalleolar equivalent fracture was higher on all reported X-ray findings than the sensitivity obtained by the reported MRI findings of deltoid ligament injury. CONCLUSION PM displacement on X-ray is a useful adjuvant along with external rotation stress radiography and MRI evaluation of deep deltoid integrity to distinguish between stable and unstable fracture patterns and thus helps facilitate treatment decisions.

Abstract
BACKGROUND Adult acquired flatfoot deformity (AAFD) is a complex and progressive deformity involving the ligamentous structures of the medial peritalar joints. Recent anatomic studies demonstrated that the spring and deltoid ligaments form a greater medial ligament complex, the tibiocalcaneonavicular ligament (TCNL), which provides medial stability to the talonavicular, subtalar, and tibiotalar joints. The aim of this study was to assess the biomechanical effect of a spring ligament tear on the peritalar stability. The secondary aim was to assess the effect of TCNL reconstruction in restoration of peritalar stability in comparison with other medial stabilization procedures, anatomic spring or deltoid ligament reconstructions, in a cadaveric flatfoot model. METHODS Ten fresh-frozen cadaveric foot specimens were used. Reflective markers were mounted on the tibia, talus, navicular, calcaneus, and first metatarsal. Peritalar joint kinematics were captured by a multiple-camera motion capture system. Mild, moderate, and severe flatfoot models were created by sequential sectioning of medial capsuloligament complex followed by cyclic axial loading. Spring only, deltoid only, and combined deltoid-spring ligament (TCNL) reconstructions were performed. The relative kinematic changes were compared using 2-way analysis of variance (ANOVA). RESULTS Compared with the initial condition, we noted significantly increased valgus alignment of the subtalar joint of 5.1 ± 2.3 degrees (P = .031) and 5.8 ± 2.7 degrees (P < .01) with increased size of the spring ligament tear to create moderate to severe flatfoot, respectively. We noted an increased tibiotalar valgus angle of 5.1 ± 2.0 degrees (P = .03) in the severe model. Although all medial ligament reconstruction methods were able to correct forefoot abduction, the TCNL reconstruction was able to correct both the subtalar and tibiotalar valgus deformity (P = .04 and P = .02, respectively). CONCLUSION The TCNL complex provided stability to the talonavicular, subtalar, and tibiotalar joints. The combined deltoid-spring ligament (TCNL) reconstructions restored peritalar kinematics better than isolated spring or deltoid ligament reconstruction in the severe AAFD model. CLINICAL RELEVANCE The combined deltoid-spring ligament (TCNL) reconstruction maybe considered in advanced AAFD with medial peritalar instability: stage IIB with a large spring ligament tear or stage IV.

Abstract
INTRODUCTION The "logsplitter injury" is a special type of ankle fractures that results from high energy violence with combined rotational forces and axial loads. So far, the diagnose and treatment of "logsplitter injury" remain largely unsettled and related literature is rare. PATIENT CONCERNS An 18-year-old male fell from a fence and got his left ankle injured with severe malformation and swollen condition. No open wound was observed. DIAGNOSIS Logsplitter injury, ankle fracture (AO/OTA classification 44C1.1, Lauge-Hansen classification: pronation-external rotation). INTERVENTIONS AND OUTCOMES The patient was initially treated by internal fixation of fibular, repair of deltoid ligaments, and 1 syndesmotic screw fixation. When the X-ray applied after surgery, another 2 syndesmotic screws were performed to enhance stability. The syndesmotic screws were removed at 12-week and 16-week respectively. The patient was allowed for full weight-bearing immediately. However, the syndesmotic space was slightly increased compared to the contralateral side in CT views at 1-year follow-up, the function outcome was satisfied. CONCLUSION The logsplitter injury is a high-energy ankle fracture that requires both axial and rotational load. It is categorized as 44B or 44C by the AO/OTA classification. In the classification scheme of Lauge-Hansen, our case is in line with the pronation-external rotation classification. Anatomic reduction and fixation of ankle syndesmotic injuries are required to restore the biomechanics of the ankle joint so that long-term complications can be prevented. How to fixation the syndesmosis, whether to reconstruct the deltoid ligament remains in debate in the treatment of logsplitter injury, whether and when to remove the syndesmotic screws were still debated. Correct surgical intervention is successful in the treatment of "logsplitter injury", however, the optimal fixation of syndesmosis and repair of deltoid ligaments need further investigate.

Abstract
BACKGROUND A spring ligament tear is commonly present in advanced stages of adult acquired flatfoot deformity (AAFD). Previous anatomic studies have demonstrated that the superficial deltoid ligament blends with the superomedial spring ligament, forming the tibiocalcaneonavicular ligament (TCNL). Adding allograft TCNL reconstruction to osseous correction has been suggested to augment medial peritalar stability in advanced AAFD with large spring ligament tears. We aimed to investigate the clinical and radiographic outcomes of TCNL reconstruction for flexible AAFD with medial peritalar instability. METHODS Fourteen feet in 12 patients who underwent osseous and TCNL reconstructions for advanced AAFD (stage IIB with large spring ligament tears or stage IV) were recruited for the study. The mean postoperative follow-up was 24 (range, 12-33) months. Pre- and postoperative clinical outcomes were assessed by the Foot and Ankle Ability Measure (FAAM), SF-36, and Patient-Reported Outcomes Measurement Information System (PROMIS). Correction of forefoot abduction and the sagittal arch were measured from pre- and postoperative weightbearing radiographs. RESULTS The FAAM Activities of Daily Living improved from 69.3 to 90.1 (P = .001). The SF-36 Physical Function (PF) and Pain subscales both improved significantly (39.4 to 87.8 and 44.6 to 93.1, respectively, P < .001 for each). The PROMIS PF improved from 38.2 to 46.8 (P = .002) and the PROMIS Pain Interference (PI) from 62.6 to 50.1 (P = .003). Radiographic measures showed an improved anterior-posterior (AP) talo-first metatarsal angle of 24.7 to 11.8 degrees (P < .001) and talonavicular coverage angle of 47.4 to 23.1 degrees (P < .01). An improved Meary's angle of 29.7 to 12.5 degrees (P < .001) and a calcaneal pitch angle of 11.7 to 16.9 degrees (P = .14) were noted in the lateral view. CONCLUSION Considering the anatomic characteristics of the deltoid-spring ligament complex, TCNL reconstruction may play a significant role in maintaining peritalar stability when performed with osseous correction. Deltoid-spring ligament (TCNL) reconstruction is a viable surgical option for those with advanced stage AAFD with medial peritalar instability that leads to improved functional and radiographic outcomes.

Abstract
BACKGROUND External rotation stress (ERS) identifies ankle instability after fibular reduction of rotational ankle injuries. Combined hindfoot and ankle motions and an inconsistent starting position could mask differing degrees of instability resulting from syndesmotic and/or deltoid ligament disruption. The goal of this work was to use full 3D talar kinematics to evaluate the effects of hindfoot orientation and foot starting position during ERS on the ability to detect instability caused by ligament disruptions. METHODS Six cadaveric ankles with metallic fiducial markers were CT scanned in neutral and 3 stress positions: varus hindfoot internal rotation stress (IRS-var), valgus hindfoot ERS (ERS-val), and varus hindfoot ERS (ERS-var). Scans were obtained in stress positions after transecting the deep deltoid ligament (tDDL) and then the syndesmotic ligaments (tDDL+Syn). Talar rotations and translations were computed in the axial, coronal, and sagittal planes in each stress position. Changes in a fixed center of rotation (CoR) relative to the intact sequence were calculated. RESULTS Axial plane rotation beginning from IRS-var increased significantly for each level of ligamentous instability (P < .05 for all conditions) (10.9 degrees, intact; 14.1 degrees, tDDL; 22.7 degrees, tDDL+Syn during ERS-val; and 16.4 degrees, intact; 23.1 degrees, tDDL; 29.9 degrees, tDDL+Syn during ERS-var). With ERS-val, the talar CoR moved medially (3.6-5.4 mm) and posteriorly (0.5-5.2 mm); ERS-var moved anterior/laterally or posterior/medially depending on the specific ligamentous instability. With tDDL+Syn the ankle became grossly unstable and there were no clear trends in sagittal/coronal rotation or translation. CONCLUSION An ERS test from internal to external rotation consistently differentiates between normal, tDDL, and tDDL+Syn. Talar CoR moved outside the mortise with ligamentous instability. CLINICAL RELEVANCE Significant residual deep deltoid instability is likely underrecognized with current practice. The most discriminatory test for detecting such instability in our laboratory was an ERS test performed by internally rotating the foot to a hard, bony endpoint, positioning the hindfoot in varus, and then performing the entire external rotation maneuver while maintaining the varus hindfoot position.

Abstract
Posterior tibial tendon dysfunction (PTTD) is a progressive disorder secondary to advanced degeneration of the posterior tibial tendon, leading to the abduction of the forefoot, valgus rotation of the hindfoot, and collapse of the medial longitudinal arch. Eventually, the disease becomes so advanced that it begins to affect the deltoid ligament over time. This attenuation and eventual tear of the deltoid ligament leads to valgus deformity of the ankle. Surgical correction of PTTD is performed to protect the ankle joint at all costs. Generally, this is performed using osteotomies of the calcaneus and repair or augmentation of the deltoid ligament. Unfortunately, there has been no universal procedure adapted by foot and ankle surgeons for repair or augmentation of the deltoid ligament. Articles have discussed the use of suture and suture anchors, suture tape, nonanatomic allograft repair, nonanatomic autograft repair with plantaris, peroneal and extensor halluces longus tendons to repair and augment the deltoid ligament. There is very little literature, however, in regard to using the posterior tibial tendon to augment the deltoid ligament in accordance with hindfoot fusion for end-stage PTTD deformity. In general, the posterior tibial tendon in triple and medial double arthrodesis is generally removed because it is thought to be a pain generator. This article presents a case study and novel technique using the posterior tibial tendon to augment and repair the laxity of the deltoid ligament in an advanced flatfoot deformity.

Abstract
We evaluated the accuracy of the predictive injury sequences of the Lauge-Hansen (L-H) classification using magnetic resonance imaging (MRI) in patients with ankle fractures and determined the possible causes of mismatch. Sixty-five patients with ankle fractures who had a complete series of anteroposterior, lateral, and oblique radiographs and ankle MRI studies available were included. The fracture pattern was assigned by 2 senior orthopedic surgeons according to the L-H classification system. The syndesmotic ligaments, lateral collateral ligaments, and medial deltoid complex ligaments were evaluated on the preoperative MRI scans. Comparisons were performed between the predicted ankle ligamentous injury based on the radiographic L-H classification and preoperative MRI analysis. Of the 65 feet in 65 patients, 50 feet (76.9%) were classified as having a supination-external rotation (SER) fracture, 6 feet (9.2%) as having a pronation-external rotation fracture, 4 feet (6.2%) as having a supination adduction fracture, and 2 feet (3.1%) as having a pronation abduction fracture. The overall compatibility of the radiologic classification with the MRI classification was 66.1%. In the evaluation of 50 feet with the MRI SER designation, maximum compatibility was found for stage 4 (77.3%). The main cause for the discrepancy in the SER designation was missing the presence of deltoid ligament disruption on the plain radiographs, especially in the stage 2 and 3 SER fracture pattern. In the evaluation of deltoid complex injuries, all injuries were localized to the anterior part of the medial deltoid complex. The validity of the L-H classification system was low. A new classification system is needed to address the medial malleolus fracture or deltoid complex injuries without posterior injury. Also, stress radiographs could be added to standard radiographs for the classification to address deltoid complex injuries.

Abstract
BACKGROUND Adult-acquired flatfoot deformity (AAFD) is usually due to a combination of mechanical failure of the osteoligamentous complex that maintains the medial longitudinal arch of the foot and attenuation or complete tear of the posterior tibial tendon. Magnetic resonance imaging studies in patients with flatfoot deformities have reported the posterior tibial tendon to be pathologic in up to 100% of patients, the spring ligament in up to 87%, and the deltoid ligament in 33%. Many studies in the literature describe reconstruction of the spring ligament or the deltoid ligament associated with AAFD, but there is no study in which both (spring and deltoid) ligaments are reconstructed at the same time. We describe a novel technique to reconstruct the deltoid ligament and the spring ligament at the same time. METHODS We described the technique and evaluated 10 consecutive patients with AAFD and insufficient ankle and midfoot ligaments. RESULTS We found no postoperative complications, stiffness, or loss of correction. CONCLUSION We present a novel technique to reconstruct the failed deltoid and spring ligament during flatfoot correction. It is unique in that it uses internal brace augmentation with FiberTape® to help and protect the soft tissue healing. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
Deltoid ligament repair can be challenging, and implementation of an arthroscopic method can be useful in terms of minimizing morbidity associated with open dissection, as long as the repair is effective and durable. In this brief report, we describe a method of arthroscopic deltoid ligament repair that we have found to be useful.

Abstract
UNLABELLED Evaluation and management of ankle fractures has progressed in parallel to an evolving understanding of ankle stability. While stability of the mortise had historically been attributed to the lateral malleolus, Lauge-Hansen's contributions followed by multiple other investigations increased the emphasis on the significance of medial-sided injury in destabilizing the mortise. As the importance of the deltoid ligament has been elucidated, the means of assessing ligamentous incompetence and the prognostic significance of an unstable mortise continue to be defined.

Abstract
BACKGROUND Ankle joint stability dictates treatment in ligamentous supination external rotation ankle injuries (LSERAI). Investigation of the medial structures that support the ankle mortise is critical, and a small avulsion fracture, or "fleck", of the medial malleolus is occasionally encountered. This study aimed to assess the utility of this medial malleolus fleck sign (MMFS) in diagnosing instability requiring surgery in LSERAI. METHODS This retrospective observational study examined 166 LSERAI at a single level I trauma center. A standardized diagnostic and treatment protocol for ankle fractures was followed. LSERAI at presentation were reported as having a normal, dynamically wide, or statically wide medial clear space. Patient demographics, MMFS characteristics, and the use of operative management were recorded. RESULTS MMFS incidence in the cohort was 16 (10%) of 166 and was present in 25% of patients with unstable LSERAI. Fifteen (94%) of 16 patients with a MMFS were deemed to have an unstable LSERAI (P < .005). MMFS had a 25% sensitivity and 99% specificity in diagnosing an unstable LSERAI. For the subgroup of patients without a statically wide medial clear space, MMFS had a 50% sensitivity and 99% specificity in determining instability. CONCLUSION A MMFS may be indicative of an unstable LSERAI. With previous MRI studies demonstrating complete deltoid disruption in unstable LSERAI, we deduce the MMFS may be associated with extensive deltoid incompetence. The MMFS may help to diagnose a complete deltoid injury in LSERAI with a normal medial clear space, which could influence treatment and reduce patient morbidity, radiation exposure, and healthcare costs.

Abstract
BACKGROUND The deltoid ligament (DL) is the principal ligamentous stabilizer of the medial ankle joint. Little is known, however, about the contribution of the DL toward stabilizing the syndesmosis. The aim of this study was to arthroscopically evaluate whether the DL contributes to syndesmotic stability in the coronal plane. METHODS Eight above-knee cadaveric specimens were used in this study. A lateral hook test was performed by applying 100 N of lateral force to the fibula in the intact state and after sequential transection of the DL, anterior-inferior tibiofibular ligament (AITFL), interosseous ligament (IOL), and posterior-inferior tibiofibular ligament (PITFL). At each stage, distal tibiofibular diastasis was measured arthroscopically at both the anterior and posterior third of the incisura and compared to stress measurements of the intact syndesmosis. Measurements were performed using probes ranging from 0.1 to 6.0 mm, with 0.1-mm increments. RESULTS There was no significant increase in diastasis at either the anterior or posterior third of the tibiofibular articulation after isolated DL disruption, nor when combined with AITFL transection. In contrast, a significant increase in diastasis was observed following additional disruption of the IOL (anterior and posterior third diastasis, P= .012 and .026, respectively), and after transection of all 3 syndesmotic ligaments (anterior and posterior third diastasis, P=.001 and .001, respectively). CONCLUSION When evaluating the syndesmosis arthroscopically in a cadaveric model under lateral stress, neither isolated disruption of the DL nor combined DL and AITFL injuries destabilized the syndesmosis in the coronal plane. In contrast, the syndesmosis became unstable if the DL was injured in conjunction with partial syndesmotic disruption that included the AITFL and IOL. CLINICAL RELEVANCE Disruption of the DL appeared to destabilize the syndesmosis in the coronal plane when associated with partial disruption of the syndesmosis (AITFL and IOL).

Abstract
BACKGROUND The spring ligament is an important medial arch stabilizer. However, when disrupted, it does not cause planovalgus deformity until the foot is cyclically loaded. We propose that the tibionavicular (TN) ligament plays an important role. However, this ligament is not imaged in routine magnetic resonance imaging (MRI) sequences. METHODS A prospective case-control study using a novel MRI sequence to image the TN ligament in 20 normal feet creating a baseline appearance of the ligament. We then scanned 20 patients with adult acquired flatfoot deformity (AAFD). All patients had weightbearing anteroposterior and lateral radiographs. We followed up patients, the end point being surgery or 18 months' follow-up. RESULTS The normal ligament was reliably identified on the novel sequences. It had a reproducible appearance in 2 views, and consistent length and width. Two groups of patients were identified in the AAFD cohort: Normal TN (11/20) (The mean Meary angle was 6.8 degrees) and Abnormal TN (9/20). The ligament was thickened proximally, with distal attenuation and intrasubstance edema. On sagittal sequence, it had dorsal bulging and high signal. The mean Meary angle was 13.2 degrees ( P = .013). All patients had posterior tibial tendon dysfunction and 8 had spring ligament complex attenuation. Five patients have undergone corrective surgery compared to none in the other group. CONCLUSION This study adds to the evidence that AAFD is multifactorial. With this imaging technique, we were able to reliably image the TN ligament. We hope that including this sequence into routine scanning will help us understand its role in flatfoot deformity. This poses the question of whether this structure will play a role in reconstructive surgery in future. LEVEL OF EVIDENCE Level II, prospective comparative study.

Abstract
BACKGROUND There is no consensus on the optimal treatment or preferred method of operation for the management of acute deltoid ligament injuries during an ankle fracture fixation. This study aimed to analyze the outcomes of repairing the deltoid ligament during the fixation of an ankle fracture compared to conservative management. METHODS We retrospectively evaluated 78 consecutive cases of a ruptured deltoid ligament with an associated ankle fracture between 2001 and 2016. All of the ankle fractures were treated with a plate and screw fixation. Patients in the conservative treatment for ruptured deltoid ligament underwent management from 2001 to 2008 (37 fractures, group 1), while the operative treatment for ruptured deltoid ligament was included from 2009 to 2016 (41 fractures, group 2). The outcome measures included radiographic findings, the American Orthopaedic Foot & Ankle Society ankle-hindfoot scores, visual analog scale scores, and the Foot Function Index. All patients were followed for an average of 17 months. RESULTS Radiologic findings in both groups were comparable, but the final follow-up of the medial clear space (MCS) was significantly smaller in the group 2 ( P < .01). Clinical outcomes were similar between the two groups ( P > .05). Comparing those who underwent syndesmotic fixation between both groups, group 2 showed a significantly smaller final follow-up MCS, and all clinical outcomes were better in group 2 ( P < .05). Linear regression analysis showed that the final follow-up MCS had a significant influence on clinical outcomes ( P < .05). CONCLUSION Although the clinical outcomes were not significantly different between the 2 groups, we obtained a more favorable final follow-up MCS in the deltoid repair group. Particularly when accompanied by a syndesmotic injury, the final follow-up MCS and the clinical outcomes were better in the deltoid repair group. In the case of high-grade unstable fractures of the ankle with syndesmotic instability, a direct repair of the deltoid ligament was adequate for restoring medial stability.

Abstract
BACKGROUND There is an increasing interest in the operative treatment of deltoid ligament disruption in the setting of chronic ankle instability. Understanding the vascular anatomy of the deltoid complex is beneficial when considering operative procedures on the medial ankle and may provide insight into factors that lead to chronic deltoid insufficiency and ankle instability. METHODS Thirty-two pairs of cadaveric specimens (64 total legs) were amputated below the knee, and the tibialis anterior, tibialis posterior, and peroneal arteries were injected with India ink and Ward's blue latex. Specimens then underwent chemical debridement to identify the vascular supply to the deltoid ligament. A subset of specimens also underwent intraosseous debridement using the modified Spalteholz technique. RESULTS The vascular supply to the deltoid ligament was clearly visualized in 60 (93.8%) specimens. Fifty-eight specimens (96.7%) had arterial supply with an origin from the medial tarsal artery, 57 specimens (95%) had supply from the tibialis posterior artery, and 23 (38.3%) specimens had supply from the tibialis anterior artery. All specimens had at least 1 location of intraosseous vascular supply, either at the medial malleolus or medial talus. CONCLUSION There were 3 separate extraosseous sources and 2 intraosseous sources of vascular supply to the deltoid ligament. CLINICAL RELEVANCE Knowledge of the vascular supply may aid in identifying factors that predispose a subset of patients with medial ankle sprains to failure of conservative treatment, as well as provide useful anatomic information when considering operative treatment for chronic ankle instability.

Abstract
OBJECTIVE To review the diagnosis and treatment of ankle fractures combined with acute deltoid ligament injury. METHODS Recent literature concerning the diagnosis and treatment of ankle fractures combined with acute deltoid ligament injury was reviewed. RESULTS Misdiagnosis is common for ankle fractures combined with acute deltoid ligament injury. A diagnosis is given based on patients' complaints, symptoms, and imaging examination, even surgical exploration is necessary. Whether to repair the deltoid ligament remains controversial. CONCLUSION Deltoid ligament is an important structure to stabilize the medial ankle joint. However, treatment of different kinds of ankle fractures combined with acute deltoid ligament injury should be standardized; whether or not repair deltoid ligament is determined by the intraoperative ankle stability.

Abstract
BACKGROUND The development of valgus tibiotalar tilt following hindfoot arthrodesis is rarely discussed in the literature. The purpose of this study was to determine the incidence of valgus tibiotalar tilt and to evaluate if there were any radiographic predictors for the development of valgus tibiotalar tilt. METHODS Patients who underwent hindfoot fusion between January 1, 2004 and December 31, 2013 were identified. Charts were reviewed for demographic information and operative details. Preoperative and postoperative radiographs were reviewed for the development of tibiotalar tilt, and standardized measurements and angles were calculated. A total of 187 patients were included. There were 106 (56.7%) females and 81 (43.3%) males. The average age was 52 years (range, 11-82 years). The most common indication for surgery was adult-acquired flatfoot deformity (n = 92, 49.2%), followed by arthritis (n = 83, 44.4%). The most common procedure was triple arthrodesis (n = 101, 54%). Twenty-seven patients demonstrated tibiotalar tilt preoperatively. RESULTS A total of 51 patients (27.3%) developed valgus tibiotalar tilt postoperatively at an average of 3.6 months after surgery. We found that an increase in the preoperative Meary (lateral talar-first metatarsal) angle (hazard ratio, 1.039; 95% confidence interval, 1.002-1.077; P < .05) was associated with the development of tibiotalar tilt. An increase in the postoperative Meary angle (hazard ratio, 1.052; 95% confidence interval, 0.999-1.108; P = .0528) approached significance for the development of tibiotalar tilt. CONCLUSION The development of valgus tibiotalar tilt following hindfoot fusion was a notable phenomenon, occurring in 27% of our patient population. The preoperative Meary angle was the only radiographic measurement that was significantly associated with the development of valgus tibiotalar tilt, although the postoperative Meary angle approached significance. These findings should encourage surgeons to be aware of patients with large deformities and of their propensity to develop a valgus deformity about the ankle.

Abstract
UNLABELLED The deltoid ligament is a complex structure of the tibiotalar joint that limits the translation and tilting of the talus. It is often associated with injuries of the ankle joint. The deltoid complex ligament has 2 layers; one superficial with 4 bands and the other deep with 2 bands. Nevertheless, the prevalence and size of its components are reported with some variability in the literature. The aim of this meta-analysis is to generate weighted values of the prevalence, size, and attachment surface areas of its components. Eight studies met the inclusion criteria with a total of 142 ankle specimens. The analyses demonstrate that the most consistent component is the deep posterior tibiotalar (100%), followed by the tibiospring (≈94%), the tibionavicular (≈90%), and the tibiocalcaneal (85%). The superficial posterior ligament and the deep anterior tibiotalar ligament were the least prevalent (≈80% and ≈63%, respectively). The longest ligament was found to be the tibionavicular ligament and the shortest band was the deep posterior tibiotalar ligament. The tibionavicular ligament was the thinnest of all deltoid complex ligament components. This study yielded more accurate data on the frequency and size of its components. The possible absence of a component, particularly of the superficial layer, might compromise joint stability in acute ankle injuries.

Abstract
An ossicle around the medial malleolus is difficult to differentiate from an unfused ossification center, an avulsion fracture, and os subtibiale. Misdiagnosis can lead to inappropriate or unnecessary treatments. We describe a patient with a symptomatic ossicle of the medial malleolus in the left ankle that prevented participation in sports activities because of medial ankle pain. Plain radiography and computed tomography revealed a small ossicle associated with the anterior colliculus of the medial malleolus. Conservative treatment failed, and the patient underwent ankle arthroscopy. Instability of the ossicle was identified after the hypertrophic inflammatory synovium had been debrided. The ossicle was resected in a step-by-step manner with an arthroscopic shaver and grasper through the anteromedial accessary portal. The deltoid ligament sustained minimal damage after resection. The patient fully recovered and was able to return to sports activities 3 months after surgery. Arthroscopic resection of the ossicle at the medial malleolus requires no additional treatments of the deltoid ligament, effectively relieves symptoms, and enables the patient to return to full preinjury activities.

Abstract
BACKGROUND Infolding and retraction of an avulsed deltoid complex after ankle fracture can be a source of persistent increased medial clear space, malreduction, and postoperative pain and medial instability. The purpose of this descriptive case series was to analyze the preliminary outcomes of acute superficial deltoid complex avulsion repair during ankle fracture fixation in a cohort of National Football League (NFL) players. We found that there is often complete avulsion of the superficial deltoid complex off the proximal aspect of the medial malleolus during high-energy ankle fractures in athletes. METHODS Between 2004 and 2014, the cases of 14 NFL players who underwent ankle fracture fixation with open deltoid complex repair were reviewed. Patients with chronic deltoid ligament injuries or ankle fractures more than 2 months old were excluded. Average age for all patients was 25 years and body mass index 34.4. Player positions included 1 wide receiver, 1 tight end, 1 safety, 1 running back, 1 linebacker, and 9 offensive linemen. Average time from injury to surgery was 7.5 days. Surgical treatment for all patients consisted of ankle arthroscopy and debridement, followed by fibula fixation with plate and screws, syndesmotic fixation with suture-button devices, and open deltoid complex repair with suture anchors. Patient demographics were recorded with position played, time from injury to surgery, games played before and after surgery, ability to return to play, and postoperative complications. Return to play was defined as the ability to successfully participate in at least 1 full regular-season NFL game after surgery. RESULTS All NFL players were able to return to running and cutting maneuvers by 6 months after surgery. There were no significant differences in playing experience before surgery versus after surgery. Average playing experience before surgery was 3.3 seasons, 39 games played, and 22 games started. Average playing experience after surgery was 1.6 seasons, 16 games played, and 15 games started. Return to play was 86% for all players. There were no intraoperative or postoperative complications noted, and no players had clinical evidence of medial pain or instability at final follow-up with radiographic maintenance of anatomic mortise alignment. CONCLUSION Superficial deltoid complex avulsion during high-energy ankle fractures in athletes is a distinct injury pattern that should be recognized and may benefit from primary open repair. The majority of NFL players treated surgically for this injury pattern are able to return to play after surgery with no reported complications or persistent medial ankle pain or instability.

Abstract
BACKGROUND Anatomy of the medial collateral and spring ligament complexes has been the cause of confusion. The anatomic description is highly dependent on the source studied and little agreement exists between texts. In addition, inconsistent nomenclature has been used to describe the components. This study attempted to clarify confusion through the creation of a 3D ligament map using attachment-based dissection. METHODS Nine fresh foot and ankle specimens were observed. The medial collateral ligament and spring ligament complexes were dissected using their attachment sites as a guide to define individual components. Each component's perimeter and thickness was measured and each bony attachment was mapped using a microscribe 3D digitizer. RESULTS Five components were identified contributing to the ligament complexes of interest: the tibiocalcaneonavicular, superficial posterior tibiotalar, deep posterior tibiotalar, deep anterior tibiotalar, and inferoplantar longitudinal ligaments. The largest component by total attachment area was the tibiocalcaneonavicular ligament followed by the deep posterior tibiotalar ligament. The largest ligament surface area of attachment to the tibia and talus was the deep posterior tibiotalar ligament. The largest attachment to the navicular and calcaneus was the tibiocalcaneonavicular ligament, which appeared to function in holding these bones in proximity while supporting the head of the talus. CONCLUSION By defining complex components by their attachment sites, a novel, more functional and reproducible description of the medial collateral and spring ligament complexes was created. CLINICAL RELEVANCE The linear measurements and 3D maps may prove useful when attempting more anatomically accurate reconstructions.

Abstract
BACKGROUND There is heterogeneity in the literature regarding the anatomy and number of ligamentous bands that form the deltoid ligament (DL). Anatomic knowledge of the DL and its variations are important for surgeons who repair ankle fractures. METHODS The DL was dissected in 33 ankles from 17 formalin-fixed cadavers (mean age at death, 76.6 years) to examine its morphology. The length, width, and thickness of its constituent bands were recorded with a digital caliper. Descriptive and correlational statistics were used to investigate the relationships between band size, age at death, and sex. A literature review was conducted to compare our data to those of previous studies. RESULTS The DL has superficial and deep layers with up to 8 different bands. CONCLUSION The DL stabilizes the medial ankle and should be evaluated in flatfoot deformities and severe ankle fractures. CLINICAL RELEVANCE Anatomic knowledge of DL variations should aid the surgeon in repairing torn DLs.

Abstract
Supination external rotation ankle fractures are the most common ankle fracture subtype. Deltoid ligament injuries have often been associated with this type of injury pattern. A missed injury can lead to post-traumatic arthritis and persistent pain. The current data do not support acute deltoid rupture repair. This has been based primarily on level III and IV studies in which less than satisfactory results were reported. We believe that acute deltoid rupture repair could be indicated in select cases. We have outlined a new deltoid repair technique for use with bimalleolar, equivalent supination external rotation ankle fractures using a flexible implant and bioabsorbable anchor.

Abstract
Syndesmosis injuries occur when there is a disruption of the distal attachment of the tibia and fibula. These injuries occur commonly (up to 18% of ankle sprains), and the incidence increases in the setting of athletic activity. Recognition of these injuries is key to preventing long-term morbidity. Diagnosis and treatment of these injuries requires a thorough understanding of the normal anatomy and the role it plays in the stability of the ankle. A complete history and physical examination is of paramount importance. Patients usually experience an external rotation mechanism of injury. Key physical exam features include detailed documentation about areas of focal tenderness (syndesmosis and deltoid) and provocative maneuvers such as the external rotation stress test. Imaging workup in all cases should consist of radiographs with the physiologic stress of weight bearing. If these images are inconclusive, then further imaging with external rotation stress testing or magnetic resonance imaging are warranted. Nonoperative treatment is appropriate for stable injuries. Unstable injuries should be treated operatively. This consists of stabilizing the syndesmosis with either trans-syndesmotic screw or tightrope fixation. In the setting of a concomitant Weber B or C fracture, the fibula is anatomically reduced and stabilized with a standard plate and screw construct. Proximal fibular fractures, as seen in the Maisonneuve fracture pattern, are not repaired operatively. Recent interest is moving toward repair of the deltoid ligament, which may provide increased stability, especially in rehabilitation protocols that involve early weight bearing. Rehabilitation is focused on allowing patients to return to their pre-injury activities as quickly and safely as possible. Protocols initially focus on controlling swelling and recovery from surgery. The protocols then progress to restoration of motion, early protected weight bearing, restoration of strength, and eventually a functional progression back to desired activities.

Abstract
Syndesmotic injuries of the ankle commonly occur by an external rotation force applied to the ankle joint. Ten fresh-frozen lower extremities from cadavers were used. A specially designed apparatus was used to stabilize the specimen and rotate the ankle joint from internally rotated 25° to externally rotated 35° at a rate of 6°/s for 10 cycles. Two stages were tested (stage I, specimens intact; and stage II, simulated pronation external rotation type injury with fixation). Group 1 was fixed with a novel suture construct across the syndesmotic joint, and group 2 was fixed with a single metallic screw. The torque, rotational angle, and 3-dimensional syndesmotic diastasis readings were recorded. Three-dimensional tibiofibular diastasis was identified. The fibula of the intact specimens displaced an average of 8.6 ± 1.7, 2.4 ± 1.0, and 1.4 ± 1.0 mm in the anterior, lateral, and superior direction, respectively, when the foot was externally rotated 35°. The sectioning of the syndesmostic ligaments and deltoid ligament resulted in a significant decrease in syndesmotic diastasis and foot torsional force (p < .05). The ligament-sectioned specimen lost 57% (externally rotated) and 17% (internally rotated) torsional strength compared with the intact specimen. Groups 1 and 2 provided similar biomechanical stability in this cadaveric model of a syndesmosis deficiency.

Abstract
The calcaneonavicular (spring) ligament complex is a critical static support of the medial arch of the foot. Compromise of this structure has been implicated as a primary causative factor of talar derotation leading to the clinical deformity of peritalar subluxation. Few procedures have been described to address this deficiency. The technique we describe here is a simple yet effective method to reconstruct the spring ligament complex that can easily be used in conjunction with other more commonly used procedures for extra-articular reconstructions of this deformity. We believe this procedure allows for a more powerful deformity correction and may decrease dependency on other nonanatomic reconstructive procedures.

Abstract
Myositis ossificans traumatica is a relatively common injury associated with sports especially those involving contact. It continues to frustrate both athlete and health practitioner alike due to its continued lack of treatment options and a lengthy natural history. This case study chronicles the observation of a 34 year old recreational ice hockey player who presented 7 years post-trauma, was diagnosed with myositis ossificans traumatica and was followed up on 8 years later (15 years post-trauma). This case report is suspected to be the first published case study of its kind. The literature review outlines the various types of myositis ossificans, its incidence, pathogenesis, differential diagnoses including osteosarcoma, and the various methods/modalities reported in its treatment.
