Complications after open reduction and internal fixation of ankle fractures in the elderly

BackgroundOpen reduction with internal fixation for unstable ankle fractures is relatively predictable with excellent outcomes. However, the management of ankle fractures in the elderly remains less predictable secondary to the various co-morbidities associated with advanced age.MethodsA retrospective chart review of 216 patients over the age of 60 that sustained an ankle fracture, was performed to determine the incidence of complications after ORIF of ankle fractures in an elderly population in the perioperative course. Secondly, the incidence of complications in patients that had locking plate fixation compared to those that had non-locking plate fixation was determined. Lastly, the effect of early weight bearing on the incidence of complications was analyzed.ResultsThere was not a statistically significant difference in the complication rates between the group with co-morbidities (19.01%) and those without (11.96%). The postoperative complication with the highest incidence was wound dehiscence (9.7%), and only diabetes significantly predicted wound dehiscence. The fixation construct and weight-bearing protocol failed to significantly predict any of the indexed complications.ConclusionsOverall, the results suggest that surgical treatment of unstable ankle fractures in the elderly is fairly predictable with an acceptable complication rate. The complication rates are higher with increased age and diabetes, but they failed to reach statistical significance. Conventional plating appears to provide adequate stability without increased risk of hardware failure. In addition patients that were allowed to walk within the first 2 weeks postoperatively did not experience a higher rate of hardware failure.     

Innovative Fixation Technique for Avulsion Fractures of the Calcaneal Tuberosity

Avulsion fractures of the calcaneal tuberosity, although relatively uncommon, occur more frequently in patients with osteoporosis and in the elderly. The results of closed manipulation are poor in these fractures, usually requiring open reduction and internal fixation. However, it is difficult to fix the bone fragment rigidly, because the avulsed bone fragment is small and thin, and the bone quality of the calcaneal body in the elderly is poor. Hence, it is necessary to limit prolonged weight-bearing after the operation. We performed an innovative surgical procedure of suture fixation to the anchor screw in four cases, following which earlier postoperative rehabilitation with full weight-bearing walking and range of motion exercises was possible, and bony union was achieved without repeated displacement of the fragment in all patients. We believe this technique would prove useful in surgical management of calcaneal tuberosity avulsion fractures.     

Reverse LISS plating for intertrochanteric Hip Fractures in elderly patients

Background  

Fractures of the intertrochanteric hip are common and the treatment of unstable fractures generally requires an operative approach. In elderly patients, osteoporosis makes internal fixation problematic and frequently contributes to failed fixation and poor clinical results. We have attempted to apply the Less Invasive Stabilization System (LISS) in reverse position for the repair of intertrochanteric hip fractures in elderly patients with osteoporotic bones. A retrospective review is presented of the cases of 28 elderly patients with stable and unstable fractures of the intertrochanteric hip treated using the reverse LISS.     

New intramedullary nail for the surgical neck fracture of the proximal humerus in elderly patients

Background Fractures of the proximal humerus are common and the repair of displaced fractures generally requires an operative approach. In elderly patients, osteoporosis makes internal fixation problematic and frequently contributes to failed fixation and poor clinical results. We have developed a new intramedullary nail (pin lock nail) for the repair of surgical neck fractures of the proximal humerus in patients with osteoporotic bones. A retrospective review is presented of the cases of 19 elderly patients with two-part or three-part fractures of the proximal humerus treated using the pin lock nail. Methods We treated 19 elderly patients with a mean age of 70.5 years. There were 13 two-part surgical neck fractures, 3 two-part surgical neck fractures with non-displaced greater tuberosity fracture, and 3 three-part surgical neck fractures with greater tuberosity fracture. All fractures were treated using the pin lock nail. Clinical results were evaluated using the Japanese Orthopaedic Association score at the last follow-up examination. On radiographic evaluation, duration to bone union of the fracture, backing out of the pin and screw, penetration of the proximal pin, and varus angulations of the humeral neck were examined. Results Mean duration of follow-up was 14 months (range 6–54 months). All fractures had united at an average of 3.3 months after surgery. No backing out of the pin and screw or penetration of the proximal locking pin was seen at the time of last follow-up. Thirteen of the 16 patients had no or minimal varus angulations of the humeral neck (≤10°). The mean overall JOA score was 84.3 points (range 65.5–100). Conclusions Our data show that using the pin lock nail for the treatment of two-part and three-part humeral fractures is a reliable procedure, providing good results with careful postoperative management.     

Bicortical fixation of medial malleolar fractures: a review of 23 cases at risk for complicated bone healing

Several methods have been described for fixation of unstable medial malleolar fractures. Certain patient populations, including the elderly, those with osteoporosis and osteopenia, and patients with diabetes mellitus, are generally known to be susceptible to complications associated with ankle fracture healing. The goal of the present retrospective investigation was to review the outcomes of a series of patients who had undergone medial malleolar fracture repair using fully threaded bicortical interfragmental compression screw fixation. Patients were included in the present series if they had undergone bicortical fixation of an unstable ankle fracture with a medial malleolar fracture component, in addition to having at least 1 of the following comorbidities: age 55 years or older, osteoporosis or osteopenia, diabetes mellitus, peripheral arterial disease, end-stage renal disease, chronic kidney disease, previous kidney transplantation, peripheral neuropathy, or current tobacco use. A total of 23 ankle fractures in 22 consecutive patients met the inclusion criteria. The mean age of the patients was 69.52 (range 45 to 89) years; 17 were female (77.27%) and 5 were male (22.73%). Of the 23 medial malleolar fractures, 21 (91.3%) achieved complete, uncomplicated healing. The mean interval to union was 62.6 (range 42 to 156) days. A total of 4 complications (17.39%) were noted, including 1 nonunion (4.35%), 1 malunion (4.35%), and 2 cases of painful retained hardware (8.7%). From our experience with this series of patients, bicortical screw fixation for medial malleolus fractures appears to be an acceptable alternative for fixation that provides a stable construct for patients at greater risk of bone healing complications.     

Talar neck fractures

Clinical management of talar neck fractures is complex and fraught with complications. As Gaius Julius Caesar stated: "The die is cast"; often the outcome of a talar neck fracture is determined at the time of injury. The authors believe, however, that better results can be achieved by following some simple guidelines. The authors advocate prompt and precise anatomic surgical reduction, preferring the medial approach with secondary anterolateral approach. Preservation of blood supply can be achieved by a thorough understanding of vascular pathways and efforts to stay within appropriate surgical intervals. The authors advocate bone grafting of medial neck comminution (if present) to prevent varus malalignment and rigid internal fixation to allow for joint mobilization postoperatively. These guidelines may seem simple, but when dealing with the complexity of talar neck fractures, the foot and ankle surgeon needs to focus and rely on easily grasped concepts to reduce poor outcomes.     

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.     

Frakturversorgung des oberen Sprunggelenks im hohen Lebensalter

Background

Osteoporotic fractures of the ankle were observed three times more often in the year 2000 than in the year 1970 and it is predicted that this will increase another three times by the year 2030. The most important predictive values for ankle fractures in the elderly are smoking, multipharmacy and poor mobility.

Injury patterns

Conservative treatment only seems to be successful in stable ankle fractures with good surrounding soft tissue. Pronation-abduction (PA) fractures most commonly affect elderly females and 90?% of the cases present as the very unstable type III. Unstable fractures, such as PA type III, supination-eversion (SE) and pronation-eversion (PE) fractures type IV can be treated better by 2-stage open reduction internal fixation (ORIF). Because the PA type III fracture is often associated with dorsal dislocation of the foot it is proposed that this type should be classified as type IV, which needs urgent surgery to prevent further soft tissue damage.

Therapy

Recommended techniques are the K-wire cage or fibula-pro-tibia technique. Locking plates are also preferred for stable fracture fixation. According to the recommended preoperative computed tomography (CT) scan a Volkmann’s fracture should be fixed through a posterolateral approach. The additional tibiotarsal internal transfixation should remain for 6-8 weeks after ORIF until it is changed to a protective lower leg cast after wound healing. An underlying osteoporosis should be diagnosed and inpatient treatment of this entity should be initiated by trauma surgeons whereby coordination training is also important.

Conclusion

Due to the increasing number of ankle fractures in the elderly particularly in postmenopausal women with osteoporosis, the insufficient diagnostics and therapy of osteoporosis and because the number of these difficult to treat fractures will increase by a factor of 3 by 2030, special surgical techniques and particularly implants are necessary for unstable ankle fractures types PA III, SE IV and PE.     

Percutaneous fixation of forefoot, midfoot, hindfoot, and ankle fracture dislocations

Open reduction with rigid internal fixation is the basic principle for surgical management in foot and ankle trauma. High-risk patients present a surgical dilemma for the foot and ankle surgeon because the possible complications are magnified in this patient population. Percutaneous fixation is a unique alternative for achieving anatomic stabilization without increased physical strain to the patient. The significant advantages of percutaneous fixation include minimizing damage to the vascular supply, maintaining and preserving a stable soft tissue envelope, and decreasing the potential risk for infection. This article provides an overview of percutaneous surgical fixation methods and their role in foot and ankle trauma for the high-risk patient.     

Percutaneous Gallagher nail stabilisation for fragility ankle fracture

Osteoporotic fragility fractures of the ankle in the elderly present a difficult challenge for the orthopaedic surgeon. There is a high incidence of complications with both operative and non-operative treatment. We have treated nine such fractures by closed reduction and percutaneous ankle stabilisation using a transarticular Gallagher nail introduced via the calcaneum and directed through the talar dome into the tibia. The median patient age was 81 years (range 60–101 years). Mean duration of patient follow-up was 34 months. All the fractures maintained satisfactory alignment and healed without delay. Pain-free transfer with assistance was possible in all patients by 8 weeks post-operatively. Nails were removed in eight patients. Six patients returned to pre-fracture mobility status. Union was achieved in eight cases. No wound complications occurred. Gallagher nail percutaneous trans-calcaneal stabilisation provides a means of sole definitive fixation in the management of unstable osteoporotic ankle fractures in the elderly.     

Current controversies in nonoperative management of Type II odontoid fractures in the elderly

The study design was a review of the literature. The objective was to assess the outcomes of nonoperative management of Type II odontoid fractures in the elderly population. Type II odontoid fractures in the elderly population are associated with high morbidity and mortality rates, and the current treatment recommendation is quite controversial. This article reviews the current literature on nonoperative versus operative treatment of Type II odontoid fractures in the elderly population, in hopes of drawing conclusions for the best approach to these patients. MEDLINE and PubMed databases were searched to identify articles. Studies included were those involving elderly patients with Type II odontoid fractures, who were managed nonoperatively. Studies assessing the different methods of operative fixation were excluded. An algorithm taking into account the morbidities associated with the treatment option versus the long-term outcomes in elderly patients with Type II odontoid fractures would be extremely beneficial for spine surgeons to aid in deciding whether or not to operate. Nondisplaced fractures may be appropriately treated nonoperatively in a collar with close follow-up and early mobilization. Halo–vest immobilization should be used sparingly in the elderly population, as it is associated with significant morbidity. Cervical collars appear to have less morbidity than halo–vest immobilization with success in the less displaced fracture patterns. Lastly, operative treatment for displaced, unstable fractures can improve patient outcomes.     

The Role of Secondary Imaging Techniques for Assessing Bone Mineral Density in Elderly Ankle Fractures

Elderly ankle fractures in the elderly represent a substantial healthcare burden. Dual-energy x-ray absorptiometry (DXA) is the gold standard for diagnosis of osteoporosis. However, there is emerging research regarding secondary imaging techniques to evaluate bone mineral density (BMD). The purpose of this systematic review was to summarize the role of secondary imaging techniques for measuring BMD in elderly ankle fractures. A literature search was undertaken using relevant search terms. Articles were screened for suitability and data extracted where studies met inclusion criteria and were of sufficient quality. Eight studies were included in the systematic review. Computed tomography (CT) may have a role in preoperative surgical planning, provide an explanation for injury patterns in elderly patients, and may be correlated with clinical outcomes. High-resolution peripheral quantitative CT may be better suited than DXA for the assessment of ankle fractures due to the resolution of the image and its ability to distinguish between bone compartments, as well as provide a more accurate estimation of bone quality. Quantitative ultrasound has shown promise as a tool for measuring BMD in patients with osteoporosis, but is not able to detect osteoporosis in patients with ankle fractures. This paper helps define the role of each modality in the spectrum of care in the evaluation of osteoporosis as it pertains to elderly ankle fractures.     

A systematic review of ankle fracture treatment modalities in diabetic patients

AimThis systematic review evaluated the surgical outcomes of various ankle fracture treatment modalities in patients with Diabetes Mellitus as well as the methodological quality of the studies.MethodsFor our review, four online databases were searched: PubMed, MEDLINE (Clarivate Analytics), CINAHL (Cumulative Index to Nursing and Allied Health) and Web of Science (Clarivate Analytics). The overall methodological quality of the studies was assessed with the Coleman Methodology Score. Data regarding diabetic ankle fractures were pooled into three outcomes groups for comparison: (1) the standard fixation cohort with management of diabetic ankle fractures using ORIF with small or mini fragment internal fixation techniques following AO principles, (2) the minimally invasive cohort with diabetic ankle fracture management utilizing percutaneous cannulated screws or intramedullary fixation, and (3) the combined construct cohort treated with a combination of ORIF and another construct (transarticular or external fixation).ResultsThe search strategy identified 2228 potential studies from the four databases and 11 were included in the final review. Compared to the standard fixation cohort, the minimally invasive cohort had increased risk of hardware breakage or migration and the combined constructs cohort had increased risk of hardware breakage or migration, surgical site infection and nonunion. Limb salvage rates were similar for the standard fixation and minimally invasive cohorts; however, the combined constructs cohort had a significantly lower limb salvage rate compared to that of the standard fixation cohort. The mean Coleman Methodology Score indicated the quality of the studies in the review was poor and consistent with its limitations.DiscussionThe overall quality of published studies on operative treatment of diabetic ankle fractures is low. Treating diabetic ankle fractures operatively results in a high number of complications regardless of fixation method. However, limb salvage rates remain high overall at 97.9% at a mean follow-up of 21.7 months. To achieve improved limb salvage rates and decrease complications, it is critical is to follow basic AO principles, respect the soft tissue envelope or utilize minimally invasive techniques, and be wary that certain combined constructs may be associated with higher complication rates.Level of evidence2.     

Management of distal humeral fractures in the elderly

Although relatively uncommon, fractures of the distal humerus in the elderly patient population are significant injuries of which optimal management is a subject of debate in orthopaedic literature. The combination of complex anatomy, poor bone quality and extensive comminution often seen with these fractures makes successful treatment difficult. Currently, most surgeons support surgical fixation of distal humeral fractures with the belief that restoration of the patient's native elbow joint provides the best opportunity for a good functional outcome. Others have proposed the use of total elbow arthroplasty as a primary treatment method for geriatric distal humeral fractures based on the difficulties associated with ORIF and the relatively low demands of this patient population. To date, there have been no prospective randomised trials comparing these two treatment alternatives, and a comparison of available outcome data shows good functional outcome for both forms of fracture management. With the aging of the population and an associated increase in the incidence of distal humeral fractures, the debate over the optimal treatment regime will undoubtedly continue.     

Operative treatment of ankle fractures: a minimum ten-year follow-up

The long-term outcome of 25 patients with bimalleolar fractures of the ankle was assessed ten to fourteen years following their fractures using the Phillips scoring system. All patients had undergone open reduction and anatomical internal fixation (as described in their operative notes in the medical records). 52% of patients had a good or excellent overall outcome while 24% had a poor overall outcome. This study has the longest follow-up period (10 to 14 years) to date on the outcomes of internal fixation of bimalleolar ankle fractures and demonstrates a higher percentage of poorer outcomes than has been previously described. This trend appears to be predictable as other studies with shorter term follow-up have already established a trend of increasing radiological evidence of post-traumatic arthritis with successively longer-term outcome reports.     

Shaft fractures of the clavicle: current concepts

Fractures of the clavicle are common and have been typically addressed to nonoperative treatment. Favorable results, which predominantly were achieved in the young and adolescents, were supposed to be usual in midshaft clavicular fractures. However, in the presence of comminution or complete displacement, especially when occurring in females or elderly patients, there is a marked risk of nonunion, malunion, and poor outcome. Thus, many authors prefer primary surgical stabilization, when risk factors add up. Plate fixation and intramedullary stabilization seem to be equally favored. Though, indications for operative management remain controversial. Further prospective randomized comparative clinical trials are necessary for a well-founded risk-benefit analysis.     

Type II odontoid fractures in the elderly: an evidence-based narrative review of management

Considerable controversy exists regarding the optimal management of elderly patients with type II odontoid fractures. There is uncertainty regarding the consequences of non-union. The best treatment remains unclear because of the morbidity associated with prolonged cervical immobilisation versus the risks of surgical intervention. The objective of the study was to evaluate the published literature and determine the current evidence for the management of type II odontoid fractures in elderly. A search of the English language literature from January 1970 to date was performed using Medline and the following keywords: odontoid, fractures, cervical spine and elderly. The search was supplemented by cross-referencing between articles. Case reports and review articles were excluded although some were referred to in the discussion. Studies in patients aged 65 years with a minimum follow-up of 12 months were selected. One-hundred twenty-six articles were reviewed. No class I study was identified. There were two class II studies and the remaining were class III. Significant variability was found in the literature regarding mortality and morbidity rates in patients treated with and without halo vest immobilisation. In recent years several authors have claimed satisfactory results with anterior odontoid screw fixation while others have argued that this may lead to increased complications in this age group. Lately, the posterior cervical (Goel–Harms) construct has also gained popularity amongst surgeons. There is insufficient evidence to establish a standard or guideline for odontoid fracture management in elderly. While most authors agree that cervical immobilisation yields satisfactory results for type I and III fractures in the elderly, the optimal management for type II fractures remain unsolved. A prospective randomised controlled trial is recommended.     

Probleme und Kontroversen in der Behandlung von Sprunggelenkfrakturen

Ankle fractures are the most frequent injuries of a load-bearing joint. Their treatment belongs to the daily routine in trauma surgery. However, despite an increased understanding of the mechanism of injury and relatively straightforward fixation techniques, the medium- to long-term results are often less than satisfactory. The following article therefore explicitly focusses on unsolved problems and controversies in the treatment of ankle fractures in the light of the current literature. These include the therapeutic and prognostic relevance of frequently used classification systems, criteria for the indication for surgery, frequent hazards in internal fixation, the question of whether and how to fix the posterior malleolus, and the detection and treatment of syndesmotic instability. Furthermore, trauma surgeons face the increasing incidence of ankle fractures in the elderly. The presence of osteoporosis, diabetes mellitus and neuropathic osteoarthropathy represents a special challenge.     

Fixation Strategies to Prevent Screw Cut-Out and Malreduction in Proximal Humeral Fracture Fixation

Fixation of proximal humerus fractures with precontoured, fixed angle devices has improved operative management of these difficult injuries, particularly in patients with osteoporosis. However, recent data has revealed that fixation with these constructs is not without complications, particularly screw cut-out and loss of reduction. Multiple strategies have been developed to decrease the number of complications. We offer a surgical technique combining suture augmentation of the proximal humerus with locked plate fixation utilizing short screws.     

Early complications of surgery in operative treatment of ankle fractures in those over 60: A review of 186 cases

Introduction

Ankle fractures are among the most common injuries of the lower extremity encountered by orthopaedic surgeons. With increasing population age and osteoporosis, the prevalence of these fractures is expected to increase. The aim of this study was to evaluate complications and the need for revision surgery after the surgical treatment of ankle fractures in patients over 60 years of age. We report the outcomes of 186 consecutive patients who underwent operative treatment for rotational ankle fractures in our institution from 2007 to 2010.

Materials and methods

Data were collected retrospectively for the purpose of this study. The outcome measures included minor complications which did not need further surgical intervention, that is, superficial wound infections, delayed wound healing, prominent implants and skin irritation, and major complications that prompted surgical intervention (due to deep wound infection, loosening of implants or loss of fixation). Medical complications were also recorded. Long-term complications (postoperative osteoarthritis) were not assessed in this study. Logistic regression analysis and Fisher's exact test were used to identify factors predicting higher risk of complications.

Results

The average age was 70.67 years (standard deviation (SD) 7.40). There were 132 (71%) females and 54 (29%) males. The overall rate of complications was 21.5% with 10.8% of them being major complications prompting surgical intervention for wound washout, removal of implants and revision of fixation. Statistical analysis showed that smoking, age, diabetes, local factors (osteopaenia, peripheral neuropathy, peripheral vascular disease, lymphoedema and venous insufficiency) and modified Charlson score were significantly associated with occurrence of complications. Gender had a marginally significant effect. Coronary artery disease and fracture type (Weber classification) did not have a significant effect on the outcome.

Discussion and conclusion

Our data show that surgical treatment of ankle fractures in the elderly is associated with a high rate of complications. The factors predicting a high rate of complications include smoking, age, diabetes, local factors and a higher modified Charlson score. It is important to bear the factors in mind whilst deciding whether surgical treatment should be used in the treatment of such fractures in the elderly and explains these to patients at the time of obtaining consent. Further large-scale studies are needed to validate the predictive value of the suggested modified Charlson score.
