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.

Retrospective Comparative Study

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.

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.

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.

Deltoid Ligament Injury

Deltoid ligament injury is thought to be rare. Signs of complete rupture of the deltoid ligament may be subtle or interpreted as another injury condition and thus are often missed acutely. No standardized method has been created to evaluate medial ligament insufficiency in acute or chronic laxity. To establish a diagnostic test for suspected isolated ruptures of the deltoid ligament, 32 subjects with no previous ankle injury underwent valgus stress radiography and nonstressed radiography of both ankles. Stress radiography in this study showed that there is a measurable but minimal range of talar tilt on valgus stress in previously uninjured ankles. This study provides the basis for diagnosis of the rare isolated rupture of the deltoid ligament of the ankle.
