Clinical outcomes following treatment of deep surgical site infection after fixation of calcaneal fractures: A retrospective case-control study

INTRODUCTION

Deep surgical site infection (SSI) may be a complication of open reduction and internal fixation (ORIF) of calcaneal fractures. This study aimed to describe the characteristics of patients with deep SSI following ORIF of calcaneal fractures via extensile lateral approach (ELA). We compared clinical outcomes of these patients, with a minimum follow-up of one year after successful treatment of deep SSI with a matched control group.

METHODS

In this retrospective case-control study, demographic data, fracture characteristics, bacterial pathogens, medical treatments and surgical approaches were collected, also the outcome was evaluated by the visual analog scale (VAS) for pain, foot function index (FFI) and AOFAS ankle-hindfoot score. The differences in Böhler and Gissane's angles between infected and contralateral feet were measured. By matching a control group of uninfected cases, clinical outcomes were compared between 2 groups using the Mann-Whitney U test.

RESULTS

Among 331 calcaneus fractures in 308 patients (mean age, 38.0 ± 13.1; male/female ratio, 5.5), 21 had deep SSI (6.3 %). There were 16 (76.2 %) males and 5 (23.8 %) females with a mean age of 35.1 ± 11.7 years. Thirteen (61.9 %) patients had unilateral fractures. The most common Sanders Type was found to be type II. The most frequent type of detected microorganisms was Staphylococcus species. Intravenous antibiotic therapy, mostly clindamycin, imipenem and vancomycin, based on the microbiological results, was prescribed with a mean±SD duration of 28.1 ± 16.5 days. The mean number of surgical debridements was 1.8 ± 1.3. Implants needed to be removed in 16 (76.2 %) cases. Antibiotic-impregnated bone cement was applied in three (14.3 %) cases. The clinical outcomes of 15 cases (follow up, 35.5 ± 13.8; range, 12.6-64.5 months) were 4.1 ± 2.0, 16.7 ± 12.3 and 77.5 ± 20.8 for VAS for pain, FFI % and AOFAS ankle-hindfoot score, respectively. Comparing with the control group (VAS for pain, 2.3 ± 2.7; FFI %, 12.2 ± 16.6, and AOFAS, 84.6 ± 18.0), only VAS pain was statistically lower in this group (p-value: 0.012). The differences in Böhler and Gissane's angles between both feet of infected cases were - 14.3 ± 17.9 and - 7.7 ± 22.5 (worse in the infected side), respectively.

CONCLUSION

Proper on-time approaches to deep infection following ORIF of calcaneal fractures may lead to acceptable clinical and functional outcomes. Sometimes aggressive approaches with intravenous antibiotic therapy, multiple sessions of surgical debridement, removal of implants and antibiotic impregnated cement are necessary to eradicate deep infection.

Malpractice claims associated with foot surgery

Surgery of the foot constitutes a substantial portion of orthopedic procedures, performed by both orthopedic surgeons and doctors of podiatric medicine. Little research exists on the medicolegal implications of foot surgery amongst these specialties. This study seeks to investigate the different medical and legal factors associated with foot surgery-based malpractice litigation. Malpractice data between 2004 and 2017 was collected using the VerdictSearch legal database. Cases involving foot surgery were identified, and case information including physician specialty, procedure, medical outcome, verdict, and payment amount were obtained. A total of 72 cases were analyzed. A majority of lawsuits involved podiatrists (76.4%), with orthopedic surgeons accounting for 15.3%. Lawsuits against podiatrists primarily occurred over elective procedures (94.5%) and most frequently involved plaintiff complaints of persistent pain (41.8%) or deformation (27.3%). Podiatrist cases most often involved allegations of failure to treat (45.5%) or inappropriate surgical procedure (27.3%). Orthopedic surgeons saw higher rates of urgent cases (45.5%), with surgical complications (27.3%) occurring at higher rates than podiatrists. Despite different trends in case types, similar rates of plaintiff victories, and mean payments were seen between podiatrists (25.5%, $911,884 ± 1,145,345) and orthopedic surgeons (27.3%, $975,555 ± 448,795). This investigation is the first to analyze malpractice trends amongst podiatrists and orthopedic surgeons. Differing factors related to medical and legal outcomes can suggest quality improvement targets for both specialties. This data may assist in reducing malpractice risk and refining patient care, particularly with regards to outlining risks, benefits, and alternatives during pre-operative counselling.

Complications in operative fixation of calcaneal fractures

OBJECTIVE

The purpose of this study focused on a number of factors that have been implicated in calcaneal complications and find the incidence of wound complications.

METHODS

This was a retrospective study. A total of 162 patients (176 feet) who underwent calcaneal fractures between 2007 and 2012 were included. The patient's personal details, age, time from injury to surgery, cause of injury, type of fracture, operative details, operating and tourniquet times were collected from hospital computers and paper records. Evidence of complications including wound infection, wound necrosis, pain, malunion, nonunion, impingement, loss of fixation, ect were studied.

RESULTS

Forty-seven of one hundred and seventy-six fractures (26.704%) had complications, wound infection was noted in seven fractures (3.977%), twelve fractures developed necrosis (6.818%), 14 fractures (7.955%) developed pain. Malunion was found in five fractures (2.841%), nonunion in two fractures (1.136%) and loss of fixation in four fractures (2.272%). Three neurologic injury was also seen in our study (1.705%). Operating time, time from injury to surgery and type of fracture had some association with complications in operative fixation of calcaneal fractures, which showed a statistically significant improvement (P=0.000, 0.031, 0.020, respectively), but there were no evidence that age and tourniquet time affect the incidence of complication after calcaneal fracture surgery (P=0.119, 0.682, respectively).

CONCLUSIONS

Despite developments in the surgical treatment of calcaneal fracture, wound complications still remain inevitable. Advanced imaging techniques, less invasive surgical procedures, wealth of anatomical knowledge, surgical experience and better postoperative care should be ensured.

Calcaneal fractures: update on current treatments

Calcaneal fractures represent 2% of all fractures and account for approximately 60% of all tarsal injuries. Motor vehicle collisions and falls are the major causes of these large force compression injuries, causing widening of the heel, loss of heel height, and articular surface displacement. A correlation has been shown between restoration of normal anatomy and satisfactory functional outcome. Once the basic principles of calcaneal fractures are understood, including the anatomy, the radiographic findings, and the challenges that these complicated fractures present, the physician can then be ready with the armamentarium that allows for a patient-specific and injury-specific plan.
