Higher complication rate after nail compared with plate fixation of ankle fractures in patients aged 60 years or older: a prospective, randomized controlled trial

The fibular intramedullary nail versus plate fixation for ankle fractures in adults: a systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

The effectiveness and safety of fibular intramedullary nail fixation (FINF) compared to plate fixation (PF) in treating ankle fractures among adults remains unclear. Therefore, we conducted a meta-analysis to assess the efficacy and safety of FINF versus PF, aiming to provide orthopedic surgeons with valuable insights when choosing between the two internal fixation methods for patient treatment.

METHODS

PubMed, EMBASE, and SCOPUS were systematically searched for articles comparing FINF and PF in ankle fractures among adults. Functional outcomes, complications, and bony union were compared between the implants.

RESULTS

A total of seven studies were included in the study, involving 586 patients. The results revealed no statistically significant differences in functional outcomes between two groups at 3, 6, and 12 months postoperatively. The outcomes favoring FINF comprised a lower infection rate (RR = 0.23, 95%CI, 0.11 to 0.47, P < 0.0001). Conversely, the PF group exhibited a superior performance in terms of hardware failure rate (RR = 2.05, 95%CI, 1.16 to 3.60, P = 0.01). A statistically significant difference was observed in the results of hardware failure rate in the subgroup of studies conducted in Europe (RR = 2.74, 95%CI, 1.45 to 5.18, P = 0.002). Comparable findings were also noted in a subgroup of older adults (RR = 4.25, 95%CI, 1.57 to 11.50, P = 0.004).

CONCLUSION

This systematic review suggests that FINF exhibits comparable effectiveness in the management of ankle fractures among adults, as compared to PF. Consequently, it is imperative to further delineate the surgical indications for both FINF and PF with precision to mitigate the risk of complications. Nevertheless, larger sample sizes and multi-center RCTs are imperative to corroborate this conclusion in the future.

Intramedullary Nailing Versus Open Reduction and Plate Fixation for Lateral Malleolar Fractures: A Meta-Analysis

The fixation for lateral malleolar fracture in ankle fractures is still controversial. The purpose of this meta-analysis is to compare clinical and radiological outcomes between intramedullary nail (IMN) and plate for lateral malleolar fractures in ankle fractures. The PubMed, EMBASE, and Cochrane Library were searched for randomized controlled trials (RCTs) from databases inception to June 2023. Data on outcomes were extracted and the methodological quality of the included studies were assessed. A meta-analysis was performed using RevMan 5.3 software when the data extracted from included studies could be synthesized. Seven RCTs were included. The methodological quality of the included studies was moderate to high. The meta-analysis results showed that the infection rate of the IMN group was significantly lower than that of the plate group (RR = 0.38; 95%CI 0.18-0.82; p = .01). There were no significant differences between the 2 groups in Olerud and Molander Ankle Score (OMAS), union rate, radiological outcomes, nerve injury rate, reoperation rate, loss of reduction, and total complication rate. Our present meta-analysis demonstrated that the IMN might be a better method for the fixation of lateral malleolar fracture in ankle fracture, as the infection rate was significantly lower than a plate.

Management of High-Risk Ankle Fractures

Successful outcomes in the surgical treatment of the fractured ankle require methods that respect the soft tissue envelope and establish a stable mortise for functional rehabilitation. Ankle fractures in patients with osteopenia and in diabetic patients with deranged bone remodeling constitute high-risk injuries that may result in catastrophic complications. These patients present unique care challenges and should not be approached in the same manner as their healthy counterparts. We present the principles of treatment in high-risk ankle fractures, operative treatment philosophy illustrating techniques frequently used at our institution, and a review of current literature.

Assessing the content validity of the Manchester-Oxford Foot Questionnaire in surgically treated ankle fracture patients: a qualitative study

BACKGROUND

Roughly 10% of fractures in adults are ankle fractures. These injuries are found in both sexes and present with different fracture characteristics. The treatment varies with the patients' biology and fracture type, and the goals are to restore stability, prevent pain and maintain ankle function. Clinicians generally use outcomes like assessment of radiography, pain level, or function. The use of patient-reported outcome measures is increasing, and the Manchester-Oxford Foot Questionnaire (MOXFQ) has been shown to have good measurement properties when validated in patients with foot and ankle disorders. However, the instrument has not been validated for ankle fracture patients. This study aims to assess the content validity of the items in MOXFQ in surgically treated ankle fracture patients.

METHODS

A qualitative deductive design was used to investigate patients' response process of the MOXFQ. Individual interviews were conducted using cognitive interviewing based on the theoretical framework of the 4-step model by Tourangeau. Adult patients that were surgically treated for an ankle fracture between four weeks and 18 months were purposively sampled, and interviews followed a semi-structured interview guide. The predetermined categories were comprehension, retrieval, judgement, and response.

RESULTS

Seventeen respondents (65% females) were interviewed. Respondents' age ranged from 27 to 76 years. Some of the respondents in the early recovery phase were limited by post-operative restrictions and did not find the items in the walking/standing domain relevant. Respondents that were allowed weight-bearing as tolerated (WBAT) were able to recall relevant information for most items. Respondents with time since surgery more than 12 months had less pain and remembered fewer relevant episodes in the recall period. Items in the social interaction domain contained ambiguous questions and were generally considered less important by respondents. The summary index score lacked important concepts in measuring overall quality of life.

CONCLUSIONS

Pain was a central concept in the post-operative recovery of ankle fracture patients. The MOXFQ-subscales for pain and walking/standing had acceptable content validity in patients that were allowed WBAT. The social interaction-subscale and the summary index score had insufficient content validity for this patient population.
