Treatment of Medial Malleolus or Pure Deltoid Ligament Injury in Patients with Supination-External Rotation Type IV Ankle Fractures

[Fractures of the upper ankle joint]

Fractures of the upper ankle joint are frequent injuries and part of routine clinical trauma surgery. In recent years, treatment strategies have changed in different ways due to advances in imaging diagnostics and a better understanding of the biomechanics. In addition, new implant systems are available. The goals of the reconstruction are anatomical reduction with restoration of the joint anatomy, reconstruction of the length, rotation and axial relationships as well as the restoration of stable joint guidance. In addition to the bony reconstruction, the focus is on restoring ligamentous instabilities. Keywords that are increasingly more in focus and controversial are: the posterior malleolar fragment, syndesmosis instability, the fourth malleolus and the importance of the deltoid ligament. For a good long-term result, anatomical reconstruction remains the basic requirement, regardless of the methods used.

Advancements in minimally invasive treatment of deltoid ligament injuries combined with distal tibiofibular syndesmosis injuries

The deltoid ligament (medial collateral ligament) and the syndesmosis (a composite ligamentous structure at the distal tibiofibular junction) are critical for maintaining ankle stability. In cases of high-energy ankle fractures, these structures are often injured simultaneously, leading to instability and potential long-term complications such as post-traumatic arthritis. This review aims to explore advancements in minimally invasive techniques for the treatment of combined deltoid ligament and syndesmosis injuries, with a focus on optimizing surgical outcomes and reducing patient morbidity. Current treatment strategies primarily involve cortical screws for syndesmosis stabilization and anchor fixation for deltoid ligament repair. Recent innovations, such as bioabsorbable screws, suture-button devices with elastic micromotion, and syndesmotic plates, have demonstrated potential in improving biomechanical stability while minimizing complications. Furthermore, minimally invasive techniques, including arthroscopic repairs with suture anchors, as well as ligament reconstruction using autografts, allografts, or synthetic ligaments, are becoming increasingly popular. By incorporating these advancements, the field is moving toward more effective and patient-centered approaches to achieve anatomical and functional restoration under minimally invasive principles. Future research should focus on further validating these techniques and identifying the most effective strategies for complex injuries.

Repairing the Deltoid Ligament in Ankle Fractures Is it time for a Paradigm Shift?

BACKGROUND

It remains unclear whether repairing the deltoid ligament (DL) is beneficial in acute ankle fractures. The aim of this review is to critically review the developments in deltoid ligament repair (DLR) in ankle fractures over the course of 44 years.

METHOD

An electronic search was conducted on the PubMed and Embase database including comparative studies evaluating the effect of performing DLR in adults suffering from a closed acute ankle fracture with suspected rupture of the DL.

RESULTS

A total of 27 studies were retrieved, of which only one was a randomized study. A total of 1327 patients were reviewed (663 undergoing DLR and 664 receiving non-DLR treatment for an acute ankle fracture). Although earlier studies concluded that DLR holds little necessity in ankle fracture treatment if the anatomy of the ankle is restored, more recent studies support DLR due to more favorable clinical and radiographic outcomes.

DISCUSSION

All studies agree that restoration of the ankle anatomy to its pre-fracture state is necessary to achieve the best clinical outcome. However, there is still controversy in whether to standardize DLR in ankle fracture treatment. The literature shows a clear shift toward more frequent restoration of the DL, and in light of improved surgical techniques and implants, there is a need for more rigorous studies to provide a clear indication for DLR in acute ankle fracture treatment.

Aggressive Postoperative Rehabilitation With Platelet-Rich Plasma Therapy for a Lauge-Hansen Supination-External Rotation Type IV Ankle Fracture: A Case Report of Early Return to Sports

Supination-external rotation (SER) type IV ankle fractures, as classified by Lauge-Hansen (L-H), are highly unstable due to frequent injuries of the deltoid and distal tibiofibular ligaments. These fractures typically require open reduction and internal fixation (ORIF), followed by prolonged immobilization and delayed weight bearing. Such protocols often result in extended recovery periods, delaying the return to competitive sports. In the clinical setting, there is a growing demand for approaches that enable athletes to resume sports quickly. Platelet-rich plasma (PRP) therapy has demonstrated the potential to enhance bone and soft tissue healing. Although PRP is widely used in ligament and tendon injuries, PRP's role in fracture rehabilitation is less well established, and it is often considered supplementary. We report the case of a 17-year-old male high school rugby player who sustained an SER type stage IV ankle fracture during a match. ORIF was performed eight days post-injury using a 1/3 tubular plate and the Ziptight system. Postoperatively, the patient underwent two weeks of cast immobilization and non-weight-bearing rest. After two weeks (postoperative day 15), the cast was removed. Radiographic and ultrasonographic evaluations confirmed the fracture stability without displacement and early callus formation. Based on these findings, full weight-bearing ambulation was permitted under close supervision, as part of a structured rehabilitation plan. By the fifth week, the patient achieved full range of motion (ROM), allowing him to begin jogging. Temporary tendon gliding issues in the seventh week were treated with hydrodissection, which enabled the resumption of partial training. By the eighth week, the patient was cleared for competitive rugby. At the one-year follow-up, he reported no pain, deformity, or functional limitations and had fully resumed his preinjury level of play. This case report highlights the potential of aggressive rehabilitation combined with PRP therapy to expedite recovery in SER type stage IV ankle fractures. Further research is needed to validate these findings in larger cohorts.

Deltoid ligament injuries: A review of the anatomy, diagnosis and treatments

PURPOSE

Ankle sprains remain the most common soft tissue injury presenting to Emergency Departments. Recently, there has been increased awareness and reporting of deltoid ligament injuries in association with injuries to the lateral ligament complex as well as with fibula fractures. This article reviews the currently available literature on the anatomy of the deltoid ligament, clinical and radiological diagnosis of injuries to the deltoid ligament and treatment recommendations.

METHODS

A literature review was conducted for keywords associated with deltoid ligament injuries. MEDLINE, PubMed and Embase databases were utilised for this search. Articles were included if involving an adult population, were English-language, were related to deltoid ligament injuries (with or without associated injuries) and reported on patho-anatomy, clinical or radiological diagnosis or treatment methods.

RESULTS

A total of 93 articles were assessed for relevance from the database search, and 47 were included after the removal of irrelevant articles and duplicates. Several studies reported on the clinical findings of deltoid ligament injury, as well as the radiographic analysis. Arthroscopy was considered the gold standard of diagnosis, with authors reporting on the potential benefit of performing arthroscopic repair or reconstruction at the same time. There were no studies that provided a system for the classification of deltoid ligament injury or larger studies of treatment pathways. Long-term studies of the incidence of instability in deltoid ligament injuries were not available.

CONCLUSION

There is limited evidence available regarding deltoid ligament injuries, particularly in terms of treatment options, either in isolation or with concomitant injuries. Long-term follow-up studies are needed to obtain more accurate data on the number of complications.

A systematic review on how to diagnose deltoid ligament injuries-are we missing a uniform standard?

BACKGROUND

Up to now, there is no convincing evidence, that surgical treatment of deltoid ligament injuries, especially in the setting of ankle fractures, does result in improved outcome. One reason could be a missing diagnostic standard. The aim of the current systematic review was to analyze the applied diagnostic strategies for acute deltoid ligament injuries in outcome studies.

METHODS

MEDLINE, Scopus, Central, and EMBASE were searched through February 2022 for any original studies addressing diagnostics of acute deltoid injuries. The study was conducted per the PRISMA guidelines. The inclusion criteria were formed according to the PICOS criteria. The data assessed were study type, level of evidence, included fractures, time point and method of diagnosing deltoid ligament layers, differentiation between layers and syndesmotic injuries.

RESULTS

31 studies were included in the final analysis. Most studies (n = 28) based their decision to treat the deltoid ligament injury on radiologic findings only, with stressed radiographs (n = 18) being the most common. The radiographs were applied at one or more time points (preoperative, before ORIF, after ORIF, after ORIF and syndesmotic repair). The most frequently assessed parameter was the Medial Clear Space (MCS, n = 27) with cut-off-values considered pathological ranging between MCS > 1 mm and MCS > 6 mm.

CONCLUSION

Comparing the 31 studies shows that a standardized method to diagnose deltoid ligament injuries is missing. Further research is needed to establish evidence-based guidelines on how to diagnose acute deltoid ligament injuries.

Classifications of posterior malleolar fractures: a systematic literature review

INTRODUCTION

Complex ankle fractures frequently involve the posterior malleolus. Many classifications describing posterior malleolar fractures (PMF) exist. The aim of this study was to provide a systematic literature review to outline existing PMF classifications and estimate their accuracy.

METHODS

The databases PubMed and Scopus were searched without time limits. Only specific PMF classifications were included; general ankle and/or pilon fracture classifications were excluded. Selection and data extraction was performed by three independent observers. The systematic literature search was performed according to the current criteria of Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). The methodological quality of the included studies was quantified using the modified Coleman score.

RESULTS

A total of 110 studies with a total of 12.614 patients were included. Four main classifications were identified: Those describing the size of the posterior malleolar fracture (n = 66), Haraguchi (n = 44), Bartoníček/Rammelt (n = 21) and Mason (n = 12). The quality of the studies was moderate to good with a median Coleman-score of 43.5 (14-79) and a weighted median Coleman-score of 42.5 points. All classifications achieved a substantial to perfect score regarding the inter- and intraobserver reliability, with Mason scoring the lowest in comparison.

CONCLUSIONS

None of the reviewed PMF classifications has been able to establish itself decisively in the literature. Most of the classifications are insufficient in terms of a derivable treatment algorithm or a prognosis with regard to outcome. However, as the Bartoníček/Rammelt classification has the greatest potential due to its treatment algorithm, its reliability in combination with consistent predictive values, its usage in clinical practice and research appears advisable.

Characteristics and Effectiveness of Postoperative Rehabilitation Strategies in Ankle Fractures: A Systematic Review

OBJECTIVES

To explore the characteristics and to report on the effectiveness of postoperative rehabilitation strategies for people with an ankle fracture.

DATA SOURCES

PubMed, Cochrane Library, EMBASE, Web of Science, and CINAHL were searched to identify studies published from January 2010 to November 2021.

STUDY SELECTION

Studies that described or evaluated postoperative rehabilitation strategies for surgically repaired ankle fractures were included.

DATA EXTRACTION

Data on postoperative rehabilitation were extracted in accordance with the Template for Intervention Description and Replication guide. Quality was assessed using the National Heart, Lung, and Blood Institute's Study Quality Assessment Tools.

DATA SYNTHESIS

Meta-analysis was planned to look at the effectiveness of postoperative rehabilitation strategies. Forty studies described postoperative rehabilitation strategies without evaluating effectiveness, whereas 15 studies focused on evaluating effectiveness. Because of the large variety in postoperative strategies and outcomes, narrative synthesis was deemed most suitable to answer our aims. Characteristics of postoperative rehabilitation strategies varied widely and were poorly described in a way that could not be replicated. Most of the studies (48%) used a late weight-bearing approach, although definitions and details around weight-bearing were unclear.

CONCLUSIONS

Late weight-bearing has been the most common postoperative approach reported in the past 10 years. The variety of definitions around weight-bearing and the lack of details of rehabilitation regimens limit replication and affect current clinical practice. The authors propose to adopt consistent definitions and terminology around postoperative practices such as weight-bearing to improve evidence for effectiveness and ultimately patient outcomes.

Comparison of deltoid ligament repair and non-repair in acute ankle fracture: A meta-analysis of comparative studies

Background

Rupture of the deltoid ligament (DL) in acute ankle fracture is very common. However, there is still insufficient evidence on whether to repair the DL in acute ankle fracture. Therefore, a systematic review and meta-analysis of comparative studies was performed to report the outcome of DL repair in acute ankle fracture.

Methods

The PubMed, Cochrane Library, EMBASE and Web of Science databases were searched from the inception dates to October 31, 2020, for comparative studies. The methodological quality was evaluated based on the risk-of-bias tool of the Cochrane Collaboration for Randomized Controlled Trials (RCTs) or the Risk-of-Bias Assessment Tool for Non-randomized Studies (RoBANS). The post-operative medial clear space (MCS), final MCS, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS) score and incidence of complications were analysed.

Results

A total of 8 comparative studies involving 388 participants who suffered Weber type B or C ankle fractures were included in this meta-analysis. The results showed that the post-operative MCS, final MCS, AOFAS score and rate of complications were statistically superior in the DL repair group. For the VAS score, there was no significant difference between the DL repair group and the DL non-repair group.

Conclusions

In this meta-analysis of comparative studies, DL repair offered great advantages in terms of the post-operative MCS, final MCS, AOFAS score and rate of complications compared with non-repair. The repair of the DL in patients with acute ankle fractures might be beneficial to ankle joint stability and assist in improving the quality of ankle reduction. More high-quality and prospective studies with long follow-up durations are needed to further demonstrate the superiority of DL repair over non-repair.

The Role of Deltoid Ligament Repair in Ankle Fractures With Syndesmotic Instability: A Systematic Review

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.

The Role of Deltoid Repair and Arthroscopy in Ankle Fractures

Despite the fact that ankle fractures are common injuries, not all patients obtain satisfactory results. Historically, the deltoid ligament injury and intra-articular pathology have not often been treated at the time of fracture stabilization. Recent literature has suggested that repair of the deltoid ligament may lead to better stability of the ankle mortise. Additionally, the use of arthroscopy in conjunction with fracture fixation may allow for better identification and treatment of intra-articular lesions and improve detection and reduction of subtle instability.

Acute Deltoid Ligament Repair in Ankle Fractures: Five-year Follow-up

Direct repair of deep deltoid ruptures after traumatic ankle fracture is not commonly performed. Previous studies overlook the contributions of the medial deltoid to overall ankle stability and long-term patient satisfaction. Historically, deep deltoid injuries have been addressed indirectly through syndesmotic ligament repair. This technique fails to restore, however, the anatomic function of the primary medial stabilizing structure. The oversight of direct deltoid repair may be one contributing factor to the less than optimal outcomes after ankle fractures with syndesmotic injuries. This article reports a positive response with direct deep deltoid repair, at average 5-year follow-up, with 93% positive return to normal function.

Transarticular external fixation versus deltoid ligament repair in treating SER IV ankle fractures: a comparative study

BACKGROUND

The topic that whether the injured deltoid ligament should be repaired when associated with ankle joint fractures is still discussed. The objective of this study was to compare the clinical effect of open reduction and internal fixation (ORIF) with deltoid ligament repair (DLR) or transarticular external fixation (TEF) in treating supination-external rotation type IV (SER IV) ankle fractures.

METHODS

Between January 2012 and December 2015, 43 patients were diagnosed as SER IV ankle fractures, 20 underwent ORIF and transarticular external fixation (TEF) without DLR (group 1), 23 were treated with ORIF and DLR (group 2). The pre- and post-operative radiographic examination were performed, the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, the visual analog scale (VAS), the Medical Outcomes Short Form 36-item questionnaire score (SF-36), and the ankle range of motion (ROM) were used for functional evaluation.

RESULTS

In both groups, the three scores improved significantly after surgery, but there was no significant difference between the two groups. At 6 weeks after surgery, patients in group 2 had better ankle ROM than group 1 (29.35 ± 2.033 vs. 40.35 ± 3.550, P <  0.001), but there was no difference at 12 months postoperatively. No cases of bone nonunion or post-traumatic arthritic changes were seen during the follow-up. Patients in group 1 required a shorter time to achieve fracture union than patients in group 2.

CONCLUSIONS

ORIF with TIF is an optional strategy to manage SER IV ankle fractures as it achieves comparable functional results to ORIF with DLR. It also allows patients to start relatively earlier weight-bearing and may promote fracture union.

Fully threaded headless compression screw versus partially threaded cancellous lag screw in medial malleolus fractures: clinical and radiological outcomes

PURPOSE

The aim of this study was to evaluate the clinical and radiological results of medial malleolar fractures, which were treated with fully threaded headless compression screws and to compare the clinical and radiological results of this screws and partially threaded cancellous lag screws.

METHODS

Sixty-one patients who attended the final follow-up examination were included in the study. Group 1 comprised 29 patients applied with fully threaded headless compression screws and Group 2 comprised 32 patients with partially threaded cancellous lag screws. Radiological evaluation was made with standard radiographs. The clinical evaluations were applied using the AOFAS ankle hindfoot scale. Pain or sensitivity by touching over the medial malleolus was recorded and scored according to Visual Analog Scale.

RESULTS

No significant differences were determined between the groups with respect to age, gender, fracture type, follow-up time, bone union time and AOFAS scores. The medial sensitivity associated with implant irritation was significantly lower in Group 1. There was no need for removal of the fixation material in any patient of Group 1.

CONCLUSIONS

The results of this study showed satisfactory results in the two fixation techniques in medial malleolar fractures. However, the rates of medial sensitivity associated with implant irritation were lower in the group where fully threaded headless compression screws were used. Therefore, to prevent postoperative patient dissatisfaction caused by persistent medial sensitivity associated with implant irritation, despite successful surgical treatment, the primary choice may be fully threaded headless compression screws.

Adverse Radiographic Outcomes Following Operative Treatment of Medial Malleolar Fractures

BACKGROUND

We initiated a retrospective study on ankle fractures to assess (1) the time needed for fracture union; (2) the incidence of adverse radiographic outcomes (AROs); (3) factors that might lead to AROs; and (4) whether AROs were associated with worse function and higher incidence of post-trauma osteoarthritis (PTOA).

METHODS

From 2007 to 2016, a total of 296 patients (169 women, 127 men; average age, 48.6 years; range, 20-84) were diagnosed with a medial malleolar fracture, whether isolated or in the setting of bi- or trimalleolar fractures, and underwent open reduction and internal fixation (ORIF) or percutaneous screw fixation (PSF). The interval to fracture union, radiographic outcomes, American Orthopaedic Foot & Ankle Society (AOFAS) score at 6 months postoperatively, and the incidence of PTOA were recorded. Risk factors were identified both in univariate and multivariate analysis. The average follow-up period was 52.0 months (range, 12-118).

RESULTS

The incidence of delayed union, nonunion, and malunion were 20.3%, 3.7%, and 4.4%, respectively. The interval to fracture union was 10.3 ± 6.4 weeks. In the multivariate analysis, the risk factors for AROs were tobacco use, vertical fractures, interposed soft tissue, and fair/poor reduction. Patients with AROs had significantly worse AOFAS score at 6 months postoperatively ( P < .001) and higher incidence of PTOA ( P < .001).

CONCLUSION

AROs of medial malleolar fractures have an underestimated incidence rate and are associated with worse ankle function and higher incidence of PTOA. Risk factors including tobacco use, vertical fractures, interposed soft tissue, poor/fair reduction should be prudently taken into consideration when treating medial malleolar fractures.

Isolated Medial Malleolus Fractures: Conventional Techniques Versus Headless Compression Screw Fixation

The aim of the present study was to evaluate the clinical and radiologic results of surgically treated isolated medial malleolar fractures and compare the clinical and radiologic results of the fixation methods of headless cannulated fully threaded compression screws and cancellous lag screws and tension band wiring. We included 32 patients who attended the final follow-up examination. Group 1 consisted of 11 patients (34.4%) treated with headless cannulated fully threaded compression screws. Group 2 consisted of 10 patients (31.2%) treated with cancellous lag screws. Group 3 consisted of 11 patients (34.4%) treated with Kirschner wires and intraosseous tension wiring. Standard ankle radiographs, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale, and visual analog scale for pain were assessed. No statistically significant differences were found among the groups in regard to age, gender, preoperative fracture type, follow-up time, radiologic bone union time, and baseline AOFAS scale scores. The interval to fracture healing was 2.2 ± 0.42 months in group 1, 2.5 ± 0.71 months in group 2, and 2.45 ± 0.52 months in group 3. The AOFAS ankle-hindfoot scale score was 96.73 ± 5.55 in group 1, 93.1 ± 5.43 in group 2, and 93.73 ± 5.52 in group 3. Hardware removal was not required in any patient in group 1 but was required in 2 patients (20%) in group 2 and 3 patients (27.3%) in group 3. The visual analog scale score for pain on palpation at the medial malleolus was significantly lower statistically in the headless compression screw group (group 1; p = .003).

Early and mid-term results of transarticular external fixation in the treatment of supination-external rotation type IV equivalent ankle fractures

PURPOSE

To investigate the early and mid-term results of open reduction and internal fixation (ORIF) with transarticular external fixation (TEF) but no deltoid ligament repair (DLR) in the treatment of supination-external rotation type IV equivalent (SER IV E) ankle fractures (AO/OTA classification 44-B 3.1) and provide evidence for clinical practice.

METHODS

This study cohort consisted of 22 patients with SER IV E ankle fractures that underwent ORIF with TEF but no DLR between December 2011 and December 2014. There were 13 males and 9 females, mean age 38.9 years (range, 17-73 years). Eight cases involved the left side and 14 the right side. The causes of fractures included road traffic accidents (11 cases), falling from height (6 cases) and sports injuries (5 cases). The mean period of hospitalization was 9.8 days (range, 6-14 days). For all the patients, MRI and three-dimensional CT were done before surgery and X-rays done preoperatively and during follow-ups. The external frame was kept for 8-10 weeks. The preoperative American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was 56.86 ± 4.400, the Medical Outcomes Short Form 36-item (SF-36) questionnaire score was 57.41 ± 4.102 and the visual analog score (VAS) was 5.50 ± 1.058. Patients' main complaints about inconvenience of daily life were also recorded.

RESULTS

All the 22 patients were followed up for 24-63 months (mean, 33.6 months). None of them developed nonunion during the follow-up; pin site infection was observed in one patient and posttraumatic osteoarthritis in another. At the final follow-up, the average AOFAS score, SF-36 score and VAS score were respectively 90.59 ± 5.096, 79.59 ± 5.394 and 1.82 ± 1.181, which were significantly improved compared with the preoperative data (t = 26.221, p < 0.001; t = 11.910, p < 0.001; t = 11.571, p < 0.001). The therapeutic effect was excellent in 13 cases, good in 7 cases and fair in 2 cases, with a good-excellent rate of 90.9%. Patients' main complaints were inconvenience of clothing (17 cases) and extremity cleaning (5 cases).

CONCLUSION

In the treatment of SER IV E ankle fractures, ORIF with TEF but no DLR can achieve satisfactory outcome, but long-term effect should be confirmed by large sample randomized controlled trials.

Role for Primary Repair of Deltoid Ligament Complex in Ankle Fractures

Acute deltoid injuries may occur with ankle fractures. They are often left to heal without repair, possibly leading to chronic medial ankle instability. Stress radiographs identify the need for surgical repair of fractures or soft tissue damage. Gravity stress views have benefits over manually stressing the ankle. MRI can explore the extent of medial soft tissue injuries. Arthroscopy can evaluate and potentially treat deltoid injuries. Interposition of the deltoid may preclude adequate fracture reduction. Except with deltoid tear, fractures should be reduced and fixated, then the deltoid assessed. With persistent instability, primary repair may prevent long-term sequelae.
