Treatment of open ankle fractures. Immediate internal fixation versus closed immobilization and delayed fixation

Thirty-one open ankle fractures were treated over a period of 11 years and retrospectively reviewed with an average follow-up period of 61 months. Fifteen were managed by closed immobilization and delayed internal fixation. Sixteen were treated with immediate open reduction and internal fixation. One case in each group became infected. Functional scores at follow-up examination were the same for both groups. The fractures treated with immediate open reduction and internal fixation showed less impairment of range of motion but had a greater incidence of chronic ankle swelling. The hospitalization time was significantly shorter for the patients treated by open reduction and internal fixation. Immediate open reduction and internal fixation of open ankle fractures speed recovery with no greater incidence of infection than encountered with conservative treatment.     

Immediate internal fixation of open ankle fractures

Seventy-six consecutive displaced open ankle fractures were treated by immediate internal fixation between 1983 and 1986 at Los Angeles County University of Southern California Medical Center. Sixty-two patients were available for clinical and radiological examination at an average of 16.4 months post-fixation. Seventy-two percent of the patients had a satisfactory result. Poor results (20%) were most commonly due to non-anatomic reductions, articular surface damage, or deep infection. Deep infection occurred in 5% of the patients while 8% required late ankle arthrodesis. We believe immediate internal fixation is the treatment of choice for displaced open ankle fractures, but this form of treatment does have a significant rate of complications.     

Can Locked Fibula Nail Replace Plate Fixation for Treatment of Acute Ankle Fracture? A Systematic Review and Meta-Analysis

The standard surgical treatment for unstable ankle fractures involves open reduction and internal fixation (ORIF) with plates. However, ORIF has been associated with several complications, such as soft tissue irritation, wound infection, and nerve injury. Previous studies have shown that closed reduction and internal fixation with locked intramedullary nails (LIMNs) yields satisfactory efficacy in the treatment of ankle fractures and is associated with low complication rates. Therefore, a systematic review and meta-analysis of randomized controlled trials is imperative to provide evidence on whether or not LIMN fixation is comparable to or superior than traditional ORIF. We conducted a comprehensive literature search in the PubMed, Cochrane Library and EMBASE databases. A total of 4 randomized controlled trials involving 359 participants who suffered ankle fractures were included in this systematic review and meta-analysis. The results showed that the LIMN fixation group was statistically significant in terms of functional outcomes at the 3-month follow-up and wound-related complications. There was no statistical advantage for patients in the LIMN fixation group in terms of nonwound-related complications, total complications, or mid-term follow-up functional outcomes. There was no statistical difference between the LIMN and ORIF groups regarding operation time and quality of reduction. We believe LIMN fixation is a viable option for the treatment of unstable ankle fractures in both young and elderly individuals.     

Results of operative fixation of unstable ankle fractures in geriatric patients.

It is widely accepted that operative fixation of unstable ankle fractures yields predictably good outcomes in the general population. The current literature, however reports less acceptable results in the geriatric population age 65 years and older. The current study analyzes the outcome of the surgical treatment of unstable ankle fractures in patients at least 65 years old. Twenty three patient over 65 years old were surgically treated after sustaining 21 (91%) closed and 2 (9%) open grade II unstable ankle fractures. Fractures were classified according to the Danis-Weber and Lauge-Hansen schemes. Fracture type was predominantly Weber B (21/23, 91%), or supination external rotation stage IV (21/23, 91%). Fracture union rate was 100%. There were three significant complications including a lateral wound dehiscence with delayed fibular union in an open fracture dislocation, and two below knee amputations, neither of which was directly related to the fracture treatment. There were three minor complications; one superficial wound infection and two cases of prolonged incision drainage, all of which resolved without further surgical intervention. Complications were associated with open fractures and preexisting systemic disease. These results indicate that open reduction and internal fixation of unstable ankle fractures in geriatric patients is an efficacious treatment regime that with results that are comparable to the general population.     

Open Versus Closed Operative Treatment for Tongue-Type Calcaneal Fractures: Case Series and Literature Review

Because consensus on the optimal surgical treatment of tongue-type calcaneal fractures is lacking, this study aimed to compare outcomes and postoperative complications of open and closed surgical treatment of these fractures. For this cases series, all patients 18 years or older who underwent operative fixation of tongue-type calcaneal fractures at 2 level I trauma centers between 2004 and 2015 were considered eligible for participation. Data on explanatory and outcome variables were collected from medical records based on available follow-up. Additionally, a systematic literature review on surgical treatment of these fractures was conducted. Fifty-six patients (58 tongue-type fractures) were included. Open reduction internal fixation was performed in 33 fractures, and closed reduction internal (percutaneous) fixation was performed in 25. More wound problems and deep infections were observed with open treatment compared with the closed approach: 10 (30%) versus 3 (12%) and 4 (12%) versus 0 (0%) procedures, respectively. In contrast, revision and hardware removal predominated in patients with closed treatments: 4 (16%) versus 1 (3%) and 9 (36%) versus 8 (24%) procedures, respectively. The systematic literature review yielded 10 articles reporting on surgical treatment for tongue-type fractures, all showing relatively good outcomes and low complication rates with no definite advantage for either technique. Both open and closed techniques are suggested as accurate surgical treatment options for tongue-type calcaneal fractures. Surgical treatment should be individualized, considering both fracture and patient characteristics and the treating surgeon's expertise. We recommend attempting closed reduction internal fixation if deemed feasible, with conversion to an open procedure if satisfactory reduction or fixation is unobtainable.     

The influence of the timing of surgery on soft tissue complications and hospital stay. A review of 84 closed ankle fractures

BACKGROUND AND AIMS: Open reduction and internal fixation of an extensively swollen ankle may lead to wound closure problems, blistering, wound edge necrosis and infection. Accordingly, internal fixation should be accomplished either before or after the period of critical soft tissue swelling. The object of the study was to investigate if the timing of surgery had any influence upon soft tissue complications and hospital stay. PATIENTS AND METHODS: The clinical course of the first 6 postoperative weeks of 84 closed ankle fractures treated by open reduction and internal fixation were reviewed. Seventeen patients were not operated on early due to lack of operative capacity and were thus operated on after 5 days or more. These patients were compared to the patients operated on within 8 hours (n = 67). The groups were comparable with respect to age, gender and fracture types. RESULTS: Despite a higher incidence of primary soft tissue injuries in the early group, the patients operated on delayed had a higher incidence of wound infections (17.6% vs. 3.0%) and hospital stay was prolonged with 12.4 days compared to early surgery. All wound infections were found in grossly displaced fractures despite adequate closed reduction immediately after arrival in the hospital. CONCLUSIONS: Delayed surgery of closed ankle fractures increases the risk of soft tissue complications and prolongs hospital stay. Immediate surgery is particularly indicated in the severely displaced ankle fracture, and if not achievable, temporary reduction and immobilization is recommended.     

Immediate internal fixation of open fractures of the diaphysis of the forearm.

Immediate (within 24 h) open reduction and internal fixation of 103 open fractures of one or both bones of the forearm was accomplished in 69 patients between 1980 and 1989. Fifty-four of the 103 patients were reevaluated 1 to 7 years postinjury (average 2.5 years) to determine the efficacy of this treatment. Forty-five (90%) of the 50 patients with Grade I, II, or IIIA injuries had satisfactory results. The four patients with Grade IIIB or IIIC injuries had unacceptable results. This study demonstrates, as have previous investigations, that immediate open reduction and internal fixation of open forearm fractures provide acceptable results in Grades I, II, and selected Grade III injuries. The subdivision of Grade III fractures into A, B, and C types provides a previously unreported statistically significant difference in the results obtained in management of these injuries. The difference in results in Grade I, II, and IIIA injuries as compared to the Grade IIIB and C injuries was statistically significant (p = 0.0004). The difference in Grade IIIA injuries as compared to Grade IIIB and C injuries was also significant (p = 0.014). Immediate open reduction and internal fixation can be recommended in Grade I, II, and IIIA open forearm fractures. Although it is unclear from this report whether the results in Grade IIIB and C fractures were due to the management protocol, the severity of the initial injury, or combined factors, immediate open reduction and plate fixation yielded poor results in these injuries.     

Open ankle fractures in patients with diabetes mellitus

Complications after surgical treatment of closed ankle fractures in patients with diabetes previously have been well documented. The purpose of this study was to evaluate the union rate, infection rate, and soft tissue complication rate in open ankle fractures in patients with diabetes. Between January 1, 1981 and December 31, 2000, 14 open ankle fractures in 13 patients with diabetes were treated. The mean followup was 19 months (range, 6-84 months). All patients were followed up until union, amputation, or for at least 6 months. Nine of 14 extremities (64%) had wound healing complications. Ultimately, five patients (six extremities; 42%) had below the knee amputation. Only three of 14 fractures in three patients healed without complications. Open ankle fractures in patients with diabetes are limb-threatening injuries with high amputation and infection rates despite contemporary techniques of open reduction and internal fixation, intravenous antibiotics, and emergent irrigation and debridement.

The pattern of ankle fractures sustained by outdoor activities at the Snowdonia National Park,North Wales,United Kingdom

ObjectiveThe aim of this study was to review the pattern of ankle fractures sustained by patients brought to the Emergency Department at Ysbyty Gwynedd from The Snowdonia National Park.Materials and methodsThe study group included all patients with ankle fractures on the mountain medicine database between March 2004 and December 2006. The presence of talar shift and comminution of the medial malleolus was noted. The pattern of fractures were analysed and compared with the literature. Radiographs were obtained for 20 casualties.Results70% of these were injured whilst hill walking. Open fractures represented 12% of injuries. 75% of fractures required operative fixation. Weber B injuries were the commonest followed by Weber C and A. Talar shift was seen in 80% of the cases and 45% showed comminution of the medial malleolus.ConclusionsIn our case series we observed a high proportion of open and unstable ankle fractures, with the majority treated by operative fixation. The high rate of comminution of the medial malleolus has previously not been reported in the literature and has the potential of making operative fixation technically difficult. Encouraging the use of walking poles particularly at the time of descending may help to reduce the incidence of ankle fractures in hill walkers.

Clinical outcome of fractures of the talar body

Fractures of the talar body present a great challenge to surgeons due to their rarity and high incidence of sequelae. This study reports the medium-term results of displaced fractures of the talar body treated by internal fixation. Nineteen patients (13 M, 6 F, mean age 31) with talar body fractures were studied retrospectively to assess outcome after operative treatment. The fractures were classified as coronal (11), sagittal (6) and crush fractures (2). Six patients sustained open fractures and two had associated talar neck fractures. Average follow-up was 26 months (range: 18-43). Clinical outcome based on American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scoring was excellent function in four patients, good in six, fair in four and poor in five. Early complications included two superficial wound infections, one partial wound dehiscence, one instance of skin necrosis and one deep infection. Other complications included delayed union in one, avascular necrosis in seven and malunion in one patient. Talar injuries are serious because they can compromise motion of the foot and ankle and result in severe disability. Crush fractures of the talar body and those associated with open injuries and talar neck fractures are associated with a less favourable outcome.     

The treatment of unstable ankle fractures in patients over eighty years of age

BACKGROUND: The current study examined the outcomes of operative treatment of unstable ankle fractures in patients at least 80 years old at the time of injury. METHODS: Of 2,682 patients who presented for treatment of ankle fractures, 17 patients met the study criteria. These patients had open reduction and internal fixation after sustaining 15 closed and two open unstable ankle fractures. There were 11 type B fractures and six type C fractures by the Danis-Weber classification, and 12 supination-external rotation and five pronation-external rotation fractures by the Laugen-Hansen classification systems. RESULTS: When noncompliant patients who developed complications were removed from analysis, the fixation failure and deep infection rates were 0% each. CONCLUSIONS: These results highlight the importance of patient compliance and non-weightbearing status in the treatment of ankle fractures in patients over 80 years.     

Comparison of Early Adverse Events After Operative Treatment of Bimalleolar and Trimalleolar Fractures Versus Pilon Fractures

Ankle fractures requiring open reduction and internal fixation vary in severity from unimalleolar fractures to bimalleolar/trimalleolar (BT) fractures to pilon fractures. Consequently, the postoperative outcomes with these surgeries can vary. Most previous studies of these injuries had small sample sizes, studied a single risk factor or adverse event, or did not compare different injuries by severity. The purpose of the present study was to describe and compare the patient characteristics and postoperative outcomes of 2 high-energy ankle fractures: BT and pilon fractures. The relevant patients were identified from the American College of Surgeons National Surgical Quality Improvement Program database using the Current Procedural Terminology codes for BT and pilon fractures. Patient demographics, characteristics, comorbidities, and 30-day mortality and adverse events were recorded and compared between the 2 types of ankle fractures. More than 45% of patients with these fracture types were aged 40 to 65 years. Pilon fractures occurred more frequently in younger patients, were more likely to occur in men, required a longer hospital stay and operative time, were less likely to occur in patients with a body mass index of >30 kg/m², and conferred a greater risk of wound complications (odds ratio 1.76; p = .048) compared with BT fractures. The findings from the present study help us understand the differences in patient characteristics and potential early adverse events after open reduction and internal fixation of BT fractures versus pilon fractures.     

The Operative Treatment of Ankle Fractures: A 10-Year Retrospective Study of 1529 Patients

Ankle fractures are the second most common fracture of the lower limb and account for nearly 10% of all fractures. They range from simple to complex injuries and approximately 40% require surgical intervention. The aim of our study was to provide an up-to-date reference of the epidemiology, fracture, and fixation characteristics of operatively treated ankle fractures. We also sought to determine the number of patients undergoing further surgery through revision, implant removal, or ankle fusion. A retrospective observational study was conducted of 1529 consecutive patients that underwent operative intervention for an unstable ankle fracture between 2007 and 2017. Fractures of the distal tibia and pilon injuries were excluded. The mean age of patients was 41.8 years with 50.7% male. Unimalleolar fixation was performed in 60.1%, while bimalleolar and trimalleolar fixation was performed in 31.2% and 5%, respectively. Isolated syndesmotic fixation was performed in 3.8%. A posterior malleolus fracture was present in 28.6%, of which 31.6% underwent fixation. A further procedure was performed in 234 (15.3%) patients. Revision open reduction internal fixation was required in 1.4% and 0.8% underwent future ankle fusion. Treatment of ankle fractures makes up a sizeable part of orthopedic trauma practice with more than 1 in 7 patients requiring a second procedure. More complex fractures were predominantly seen in older females, while patients who suffered trimalleolar fractures have an increased likelihood of requiring future ankle fusion or revision. Despite this the rate of ankle fusion was <1%.     

Minimally Invasive Treatment of Ankle Fractures in Patients at High Risk of Soft Tissue Wound Healing Complications

The complex nature of ankle fractures is magnified when seen in patients at high risk of soft tissue wound healing complications. The major categories include associated soft tissue injury, diabetes, tobacco use, peripheral vascular disease, malnutrition, alcoholism, and corticosteroid use. Because of the potential for wound dehiscence and infection with open reduction and internal fixation of ankle fractures in these patients, minimally invasive procedures have been described. The aims of the present study were to assess the possibility for, and evaluate the results and complications of, minimally invasive techniques for different types of malleolar fractures in high-risk patients. We report the clinical results of 47 high-risk patients who presented with malleolar fractures from January 2007 to December 2012 and underwent minimally invasive reduction and fixation. One patient (0.5%) developed a superficial infection; however, none of the patients displayed wound dehiscence or deep infection. Five patients (10.6%) required open reduction because of intraoperative failure to achieve anatomic reduction. Using the American Orthopaedic Foot and Ankle Society ankle-hindfoot scale, 15 of the patients (36%) treated with minimally invasive techniques experienced an excellent outcome. In contrast, 23 patients (55%) had a good, 3 (7%) a fair, and 1 (2.5%) a poor outcome. The results of our study have shown that minimally invasive fixation appears to be a satisfactory method for the management of malleolar fractures in high-risk patients and could be helpful in the avoidance of the complications associated with conventional open reduction and internal fixation.

Involvement of Residents Does Not Increase Postoperative Complications After Open Reduction Internal Fixation of Ankle Fractures: An Analysis of 3251 Cases

Ankle fractures are common injuries frequently treated by foot and ankle surgeons. Therefore, it has become a core competency for orthopedic residency training. Surgical educators must balance the task of training residents with optimizing patient outcomes and minimizing morbidity and mortality. The present study aimed to determine the effect of resident involvement on the 30-day postoperative complication rates after open reduction and internal fixation of ankle fractures. A second objective of the present study was to determine the independent risk factors for complications after this procedure. We identified patients in the American College of Surgeons National Surgical Quality Improvement Program database who had undergone open reduction internal fixation for ankle fractures from 2005 to 2012. Propensity score matching was used to help account for a potential selection bias. We performed univariate and multivariate analyses to identify the independent risk factors associated with short-term postoperative complications. A total of 3251 open reduction internal fixation procedures for ankle fractures were identified, of which 959 (29.4%) had resident involvement. Univariate (2.82% versus 4.54%; p = .024) and multivariate (odds ratio 0.71; p = .75) analyses demonstrated that resident involvement did not increase short-term complication rates. The independent risk factors for complications after open reduction internal fixation of ankle fractures included insulin-dependent diabetes, increasing age, higher American Society of Anesthesiologists score, and longer operative times.     

Open reduction and internal fixation of humeral shaft fractures. Results using AO plating techniques

Thirty-six patients with an acute fracture of the humeral shaft were treated by open reduction and internal fixation using AO plating techniques. In thirty-two patients an open fracture or multiple injuries, or both, were the indications for internal fixation. Four patients were treated after non-operative treatment failed to maintain a satisfactory reduction. Follow-up was possible for thirty-four patients and showed that thirty-three fractures united primarily and one failed to unite, necessitating two subsequent procedures. Two superficial wound infections in patients with an open fracture and one transient postoperative radial-nerve palsy were the only complications. A functional range of motion in the elbow and shoulder was regained in all but six patients, and they had severe skeletal or soft-tissue injuries in the same extremity. When indicated, internal fixation using plating techniques can give good results provided the correct principles of fixation are carefully followed.     

Functional Outcomes Following Operative and Nonoperative Management of Weber C Ankle Fractures: A Systematic Review

Weber C ankle fractures are unstable ankle fractures occurring above the syndesmosis. These fractures are often managed operatively, although a small population of patients are still selected for nonoperative management. This study primarily aimed to summarize the current evidence on functional outcomes for Weber C patients managed operatively and nonoperatively. Evidence on secondary outcomes such as complications and radiographic outcomes were also reviewed. This systematic search was conducted according to PRISMA guidelines. A literature search was conducted using the EMBASE, Medline, and Central databases. A total of 26 studies were included in the final analysis. All papers studied the management of Weber C fractures using open reduction and internal fixation (ORIF). Three main functional outcome scores were identified: American Orthopedic Foot and Ankle Society score, Olerud-Molander Ankle Score, and Foot and Ankle Outcome Score. Only 1 study compared operative and conservative management, which showed similar outcomes for either option (median Olerud-Molander Ankle Score 95 [range 20 to 95] vs 100 [70 to 100], respectively). Complications associated with operative management included infection, wound dehiscence, implant failure, and malunion or nonunion. The mean rate of syndesmosis malreduction was 18.2%. This study showed that operative management, regardless of the method of ORIF used, as well as nonoperative management resulted in good functional outcomes, indicating that patient selection for either method is important. However, there is limited evidence on the complications and radiographic outcomes associated with nonoperative management. We recommend further studies to compare all ORIF methods with conservative management and examine the complications associated with nonoperative management.
