Functional assessment of transplantar nailing for ankle fracture in the elderly: 48 weeks' prospective follow-up of 14 patients

Resumption of complete weight bearing after osteosynthesis of bimalleolar fractures using locking plates

INTRODUCTION

Bimalleolar fractures represent 9% of fractures and affect 187/100,000 people per year. The gold standard for osteosynthesis is a one-third tubular or lateral locking plate and compression screwing or use of tension band wiring, with complete weight bearing planned around the 6th week. The development of locking plates seems to allow earlier resumption of weight bearing. The objective of our study was to evaluate the clinical and radiological results after internal fixation of bimalleolar fractures using locking plates with complete weight bearing authorized from the outset. The hypothesis was that this does not predispose to cutaneous or mechanical complications.

HARDWARE AND METHOD

A continuous multi-operator retrospective study was performed. The clinical and radiological data of 55 patients operated on for bimalleolar fractures were collected. All underwent osteosynthesis with medial and lateral locking plates with authorization for weight bearing from the outset.

RESULTS

Complete weight bearing was resumed at 27.4 days 14.7 [7-60] postoperatively. No non-union or malunion was found. Two patients presented with delayed medial healing without the need for hardware removal. Two patients required removal of the lateral Plate 1 month postoperatively due to infection. Seven patients presented with discomfort related to hardware, justifying its removal at 1 year. The Kitaoka score at 1 year was 94.6 7.7 [71-100].

CONCLUSION

The use of medial and lateral locking plates in bimalleolar fractures associated with complete weight bearing authorized from the outset allows complete consolidation. There was no increase in cutaneous or mechanical complications.

Outcomes after primary ankle arthrodesis in recent fractures of the distal end of the tibia in the elderly: a systematic review

PURPOSES

Management of distal tibia fractures in the elderly is complex. The results of conservative treatments may be disappointing and primary ankle arthrodesis is now regularly offered as an alternative. In this study, we aimed to review the outcomes of primary ankle arthrodesis for distal tibia fracture in the elderly.

METHODS

We conducted a systematic review of the literature, from the Cochrane, MEDLINE, and Embase databases, on studies published in English and in French between 1950 and 2020. Only studies reporting the clinical results, the function, or the complications of primary ankle arthrodesis after ankle fracture in the elderly were included.

RESULTS

We included nine studies. The total number of patients was 229: 21% of them (50/229) sustained open fractures and 41% (95/229) had three or more comorbidities. All the patients underwent a tibio-talo-calcaneal arthrodesis with a retrograde transplantar intramedullary nailing (TIMN): short nail in 52% (151/229) and long nail in 48% (78/229) of the cases. At a mean follow-up comprised between six and 21 months, 94.5% of patients (190/201) achieved bone union, 87% (123/140) recovered an ankle range of motion close to their pre-operative status, 19% (40/211) had a complication, and 11.3% (24/211) required a revision. The use of a short nail resulted in a higher rate of peri-implant complication (2%) as well as a higher rate of revision (12.4%).

CONCLUSION

Primary ankle arthrodesis in recent fractures of the distal end of the tibia in the elderly frequently results in satisfactory results. The use of a long nail may be associated with a lower rate of implant specific complications.

Treatment of bimalleolar fractures in elderly

Geriatrics continues to evolve as a specialty by adapting itself to increasingly older patients. Musculoskeletal injuries are common in these patients, who can maintain their physical capacities and autonomy for a long time, but whose bone solidness is frequently reduced by osteoporosis. Falls increase with age and because of certain medical conditions. Trauma in the geriatric population involves specific risks; thus, the treatment must be adapted not only to the fracture, but to the local conditions and the patient. Ankle injuries are particularly frequent in general traumatology but even more in geriatric traumatology. They can lead to complete loss of autonomy if the treatment is delayed and/or not adapted to the local conditions or the patient. The functional prognosis is brought into play, along with the patient's life due to loss of autonomy and general complications occurring in patients who are bed-ridden. The treatment of bimalleolar ankle fractures in older adults requires rigorous analysis at all points, which starts by evaluating the cutaneous status and viability of the soft tissues upon admission. The benefit-risk balance of the various treatment options will be assessed with the main goal being that patients recover their autonomy. This article will review this topic by answering 7 questions: 1) What are the distinctive features of elderly? Dependence on others, comorbidities, bone and soft tissue fragility are the main ones, explaining these high-risk situations and frequent complications. 2) When should a bimalleolar ankle fracture be treated surgically? The surgery must be done early, preferably within 8hours of the injury occurring, once the comorbidities have been controlled. The local conditions (skin and soft tissue damage) must be evaluated carefully as they determine the treatment. Errors are not allowed in these patients, who are often fragile and in precarious health. Definitive fixation is preferred if the skin status allows it, but one must keep temporary external fixation in mind as an option. 3) Is there still a role for conservative treatment of displaced fractures? This will produce good results when it is well done; however, the indications are rare and must be selected carefully. The main risks are secondary displacement and skin lesions inside the cast, which are sources of infection. 4) Is fixation with anatomical locking plates an advance? This is definitely an advance for these fragility fractures, which are often comminuted, as it allows return to weight bearing in certain conditions. However, the implantation rules must be followed exactly, and it is preferable to use thinner plates. 5) Does transplantar Steinmann pin fixation still have a role? It has few indications, limited to salvage situations (catastrophic local conditions, very poor general condition). External tibiocalcaneal fixation, alone or in combination, is a better option. 6) Is immediate transarticular fixation with a retrograde or antegrade locked nail a reasonable option? Fixation can be done by retrograde nailing or antegrade nailing. It is proposed to patients who are not very autonomous with a poor cutaneous status and/or severe osteoporosis. It is preferable to transplantar nailing. 7) Is immediate protected weight bearing, with or without fixation, possible? This can be considered on a case-by-case basis depending on the extent of the trauma, patient compliance and treatment carried out. LEVEL OF EVIDENCE: V, Expert opinion.

Acute Hindfoot Nailing for Ankle Fractures: A Systematic Review of Indications and Outcomes

OBJECTIVES

To assess the complication rate of hindfoot nailing of acute fractures involving the tibiotalar joint, and mortality, patient-reported outcome measures, and return to preinjury activities.

DATA SOURCES

MEDLINE; EMBASE.

STUDY SELECTION

A systematic literature search for articles in English was completed using MEDLINE and EMBASE databases on April 23, 2020. Original research articles that assessed patients with acute intra-articular fractures of the ankle joint (malleolar ankle fractures and/or pilon fractures) that were treated with a locked hindfoot intramedullary nail, inserted retrograde through the plantar surface of the foot, were selected for inclusion. Case reports (≤4 patients), studies with nonlocked implants, and non-English studies were excluded.

DATA EXTRACTION AND SYNTHESIS

A validated data extraction form was used, which included study demographics (authors, journal, date of publication, and study design), patient characteristics, implant type, and reported outcomes. Risk of bias for each included study was evaluated using the Institute of Health Economics Quality Appraisal Checklist for case series and the Risk of Bias in randomized trials tool, where appropriate. The best evidence was summarized and weighted mean values were provided when appropriate.

RESULTS

Ten case series and one randomized controlled trial were included. The overall quality of studies was poor with considerable bias. The majority of studies included elderly patients (weighted mean age 75.5 years) with diabetes (42% of patients). Overall complication rate was 16% with an 8% major complication rate (deep infection, malunion, nonunion, implant failure) and an overall infection rate of 6.2%. Pooled mortality rate was 27% with fracture union rates from 88% to 100%. Mean proportion of patients able to return to preinjury level of activity was 85%.

CONCLUSIONS

Hindfoot nailing of acute ankle and pilon fractures in elderly patients and patients with diabetes is associated with complication rates comparable with other methods of fixation. Issues with elimination of subtalar joint motion and implant complications secondary to poor implant fixation persist. The literature to date has composed of primarily Level IV studies with considerable bias. Further research is necessary to clarify the role of hindfoot nailing of acute ankle and pilon fractures.

Osteoporotic ankle fractures: A narrative review of management options

The management of Osteoporotic ankle fractures is still considered to be a challenge by many surgeons. One of the issues seems to be a lack of data focused on this special subgroup, with very little evidence of good quality. We did a narrative review of the literature in an attempt to identify the magnitude of the problem and to evaluate the evidence in support of management options.The current review of the literature has brought to light some interesting facts. Despite limited data there seems to be an in increase in the incidence of these fractures. Although we could not demonstrate any clear distinction between geriatric and osteoporotic ankle fractures from the available literature; it is clear that all geriatric fractures are not necessarily osteoporotic and neither is the reverse true. The evidence to associate osteoporotic ankle fractures with poor outcomes is weak, and factors other than osteoporosis may have a stronger influence. From this analysis, we could not establish a higher incidence of implant failure for this specific fracture group, although many modifications in technique have been proposed due to the fear of fixation failure. Hook plating and Tibia-pro fibula fixation have weak evidence in support, but posterior fibular plating is preferred due to soft tissue protection. There is weak evidence in support of Locking plates for these fractures, as publications focused on this are limited; nevertheless some advantages have been documented. Augmentation by calcium based bone graft substitutes has been reported to improve pull out strengths of screws, but again the evidence of its role in Osteoportic fractures is limited. Fibular nailing has been proposed with specific advantages in osteoporotic fibular fractures, but the concept is new and it is indicated only in a select a subgroup of cases. Some evidence exists for the use of trans-articular nails in geriatric subgroups with limited pre-injury mobility, but the technique has to be used with caution to prevent other complications.

INFERENCE

More data needs to be accumulated before clear guidelines for management of osteoporotic ankle factures are defined; however the current literature supports the need for modifications in standard ankle facture fixation methods to improve outcomes.
