Category: Trauma Introduction/Purpose: There remains a controversy to repair deltoid ligament in SER type IV equivalence of acute ankle fracture. Some surgeons prefer conservative treatment with casting while others prefer to repair deltoid ligament after distal fibular fixation. However, there is a little evidence to report comparative outcomes between the two methods. There remains a controversy to repair deltoid ligament in SER type IV equivalence of acute ankle fracture. Some surgeons prefer conservative treatment with casting while others prefer to repair deltoid ligament after distal fibular fixation. However, there is a little evidence to report comparative outcomes between the two methods. The purpose of this study was to report clinical and functional outcomes including complications between the two methods. Methods: A prospective, randomized collected data of 41 consecutive patients who were diagnosed with SER type IV equivalence acute ankle fracture and underwent either conservative treatment (20 patients) or deltoid repair (21 patients) between 2015 and 2017. A minimum follow up to be included in the study was 6 months (mean, 13.2 months; range, 6 to 30 months). The primary outcome was visual analogue scale (VAS), Short Form-36 (SF-36); physical and mental component scores, and FAAM; ADL and Sport. Pre- and post-operative SF-36, FAAM, and pain (Visual Analog Scale) were obtained and compared between the two groups using independent t-test. The secondary outcomes were time to return to activity of daily living, sports, work, and complications. Results: There were 41 patients (30 male and 11 female) with mean age of 29.7 years (range, 18-70 years) and mean BMI of 26.7 kg/m2 (range, 18.3-33.6 kg/m2). Both methods demonstrated significant improvement of post-operative functional outcomes (FAAM, SF-36, and VAS (p < 0.05 all)) compared to pre-operative period; however, there was no significant different between the two groups. Functional outcomes between casting and deltoid repair groups were time to return to activity of daily living (10.4 vs 11.7 weeks), works (12.1 vs 12.9 weeks), sport (25.9 vs 23.7 weeks), weight bearing medial clear space (2.9 vs 3.9 mm), and complications included medial side ankle pain (57 vs 15%) and painful scar (0 vs 15%) for cast and deltoid repair respectively. Conclusion: Both casting and deltoid repair were demonstrated significant improvement in terms of functional outcomes as measured with the FAAM, SF-36, and VAS in patients with SER IV equivalent ankle fracture. Although there was no significant difference of functional outcome in short term of follow-up, deltoid repair group was better in term of medial side ankle pain and lesser medial clear space widening.

Supination External Rotation

Category: Ankle; Basic Sciences/Biologics; Trauma Introduction/Purpose: In isolated lateral malleolar fractures of the supination-external rotation (SER) type and competent medial stabilizers (type II and III), non-operative treatment has yielded excellent outcome. With complete rupture of the deltoid ligament (SER type IV) fracture instability increases substantially. The rationale for operative treatment of SER type IV fractures is based upon good clinical results and previous biomechanical studies. A significant reduction of the ankle contact area that however is caused by an artificially forced lateralization of the talus in the ankle mortise has been demonstrated. Presumed resultant elevated joint contact stresses are thought to lead to ankle arthritis in the longterm. Methods: In 12 lower leg specimen SER type injuries were simulated by gradual bony and ligamentous destabilization of the ankle from lateral to medial according to the mechanism of injury as described by Lauge and Hansen. High-resolution pressure sensors placed in the ankle joint recorded tibio-talar pressure changes at physiologic weightbearing (700N) in three positions (plantigrade, 10° dorsiflexion and 20° plantarflexion). Results: With increasing instability changes of the ankle kinematics were seen in SER II and III fractures with the same trend also in SER IV lesions. In the plantigrade position, the medial clear space (MCS) increased significantly from an average of 2.5+-0.4mm (no fracture) to 3.9+-1.1mm (SER type IV fracture). However, the corresponding peak pressure increased only slightly from 2.6+- 0.5 mPa to 3.0+-1.4 mPa on average, and the contact area decreased slightly from 810+-42 mm2 to 735+-27mm2 on average representing a non-significant reduction of only 9% of the contact area (p=0.08) after the deep deltoid ligament was completely dissected.The comparison of the results in plantigrade and plantarflexed position revealed substantial differences for MCS, contact area and center of force. Conclusion: Under physiologic load SER type IV isolated lateral malleolar fracture with completely disrupted deep deltoid ligament led to a significant increase of the MCS, but neither to a significant decrease of the of the joint contact area nor significant increase of peak pressure. Clinical Relevance: The findings of this biomechanical study support the recently reported good clinical results of non-operative treatment of SER type II to IV fractures.

Background: The deep deltoid ligament (DDL) is a key stabilizer to the medial ankle and ankle mortise and can be disrupted in ligamentous supination external rotation type IV (LSER4) ankle fractures. The purpose of this study was to define the medial clear space (MCS) measurement on injury mortise radiographs that corresponds with complete DDL injury. Methods: A retrospective record review at a level 1 hospital was performed identifying patients with LSER4 ankle fractures who underwent arthroscopy and open reduction internal fixation. Chart reviews provided arthroscopic images and operative reports. Complete DDL injury was defined as arthroscopic visualization of the posterior tibial tendon (PTT). Inability to completely visualize the PTT was defined as a partial DDL injury. MCS was measured on injury mortise radiographs. Eighteen subjects met inclusion criteria. Results: Twelve subjects had complete and 6 subjects had partial DDL injury based on arthroscopic findings. Patients with complete DDL injury and those with partial DDL injury had injury radiograph MCS ranging from 5.5 to 29.9 mm and 4.0 to 5.0 mm, respectively. All patients with MCS ≥5.5 mm on injury radiographs had complete DDL injury and all patients with MCS ≤5.0 mm on injury radiographs had partial DDL injury. Conclusion: Complete DDL injury was found on injury ankle mortise radiographs as MCS widening of ≥5.5 mm, which correlated with arthroscopic visualization of the PTT. Using this cutoff, surgeons can surmise the presence of a complete deltoid ligament injury, allowing for improved preoperative planning. Level of Evidence: Level III, retrospective comparative study.

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. Level of Evidence: Level III, retrospective comparative case series.

ABSTRACT The juvenile Tillaux fracture is a transitional ankle fracture that occurs in the adolescent population. The juvenile Tillaux fracture is an avulsion injury of the distal tibia's anterolateral epiphysis as the result of excessive external rotation. The purpose of this article is to present a pediatric ankle fracture that is best described as a supination-external rotation type IV ankle injury with an associated Tillaux fragment. This fracture pattern represents a unique variant to classically described pediatric ankle fractures. Dial BL, Morwood MP, Fitch RD.

Retrospective Comparative Study

Background: The suture anchors for the repair of deltoid ligament in rotational ankle fracture are inserted mostly into the medial malleolus, but sometimes are placed into the talus depending on the rupture site. This study sought to compare the radiological and clinical outcomes of deltoid ligament repair according to using these 2 locations for suture anchor placement. Methods: The cases of 131 patients (114 patients with suture anchors on the medial malleolus and 17 patients with suture anchors on the talus) who underwent deltoid ligament repair along with ankle fracture fixation were retrospectively reviewed. Medial clear space oblique (MCSo), medial clear space perpendicular (MCSp), tibiofibular clear space (TFCS), and tibiofibular overlap (TFO) were measured as radiological outcomes, while the Olerud-Molander Ankle Score (OMAS) and visual analog scale (VAS) score for pain were calculated as clinical outcomes. The follow-up period did not differ between the 2 groups (16.8 ± 10.9 months in the medial malleolus group vs 17.9 ± 14.3 months in the talus group; P = .670). Results: There were no differences in MCSo, MCSp, TFCS, and TFO at 3 months after surgery and final follow-up. The OMAS and VAS for pain did not show intergroup differences at final follow-up. Conclusion: The surgical outcome of deltoid ligament repair in rotational ankle fracture did not differ whether the suture anchors were inserted into the medial malleolus or into the talus. Level of Evidence: Level III, retrospective comparative study.

ABSTRACT Objective: To evaluate the frequency of deltoid ligament injury in bimalleolar supination-external rotation type fractures and whether there is a correlation between the size of the fractured medial malleolus and deltoid ligament injury . Methods: Twenty six consecutive patients underwent magnetic resonance exams after clinical and radiographic diagnosis of bimalleolar supination-external rotation type ankle fractures . Results: Thirteen patients (50%) presented deltoid ligament injury associated to bimalleolar ankle fracture. Partial injury was present in seven (26.9%) patients and total injury in six (23.1%). Regarding medial fragment size, the average was 2.88 cm in the absence of deltoid ligament injury. Partial injuries presented 1.93 cm and total 2.1 cm on average . Conclusion: Deltoid ligament injury was present in 50% of bimalleolar ankle fractures. Smaller medial malleolus fragments, especially concerning the anterior colliculus, presented greater association with partial deltoid ligament injuries. Level of Evidence IV, Cross Sectional Study.

Rotation Stress

Category: Ankle, Trauma Introduction/Purpose: Isolated Lateral malleolus fracture, like any other fractures can be treated by operative or conservative treatment. Stability of ankle joint is the most important factor in deciding the type of treatment. Unstable ankle joints present superior clinical outcomes with surgical management. There are many methods to assess the stability of ankle joint such as plain x- ray films, stress radiographies and physical examination. Many studies have suggested the usage of ultrasound for diagnosis of ankle ligament injury. But, there are no reports about its use for stability assessment of isolated lateral malleolar ankle fracture. Therefore, the purpose of this study is to evaluate the value of ultrasound for stability assessment of isolated lateral malleolar fractures, compared to simple x-ray, stress radiography and arthroscopy. Methods: We have conducted a prospective study which included 13 consecutive patients who underwent arthroscopic exam and subsequent open reduction and internal fixation for isolated lateral malleolar ankle fracture. Before operation simple x-ray, external rotation stress radiographs were done. Stress ultrasound was performed to assess the anterior inferior tibiofibular ligament (AITFL) and medial deltoid ligament prior to operation. The arthroscopic findings were used as the reference standard. A standardized physical examination (tenderness and ecchymosis, external rotation stress test), simple radiography, stress radiography and ultrasound images were compared to assess the stability. Results: Deltoid ligament injury and or syndesmosis injury were verified arthroscopically in 12 cases with a clinical diagnosis (92.3%). There were 9 cases who showed unstable ankle fracture on the simple radiography. (69.2%). There were all cases who showed unstable ankle fracture on the external rotation stress radiography. (100%) In addition, for 12/13, there were acute tear of the deltoid ligament or AITFL injury on the ultrasound (92.3%). Conclusion: The results suggest that ultrasound could be used for the assessment of the instability of isolated lateral malleolar fracture.
