Delayed presentation of complex acetabular fractures: Review of literature on outcome of internal fixations with reference to extended ilio-femoral approach.

ABSTRACT:

Objective

Delayed presentation of complex acetabular fractures isn't uncommon. Surgical treatment of such fractures demand special consideration with respect to surgical approach, reduction techniques, fixation and avoidance of complications. This paper intends to review the literature with regard to the suggested treatment modalities and the reported outcome in late presentations and conclude any recommendations appropriate to the practice in current times.

Background

Displaced fractures of acetabulum, when remained untreated for more than three weeks, pose significant challenge to fracture reduction due to rapid callus formation. In 1976, Letournel described the "Extended Ilio-Femoral Approach"(EIFA) to provide adequate exposure for effective reduction of such fractures. It offered greater exposure of both anterior and posterior columns through a single window, which allowed more precise and controlled reduction of the complex fractures under vision. But despite early enthusiasm in its practice, there has been a steep decline in its application due to reported higher risk of complications. Despite the challenges, the accuracy of fracture reduction in complex acetabular fractures with late presentation was found to be superior in EIFA than the reduction that were achieved by other approaches. Hence a debate to find out the utility of this approach for late reconstruction of complex acetabular fractures (in the face of reported risks of complications) is worthwhile especially in younger patients, who are not suitable candidates for an acute hip replacement surgery and who need their native hip to function well at least for a few years, for their professional and personal high demand activities in their active youthful period.

Methods

The articles for review were retrived using Google Scholar for data retrieval as Pubmed didn't yield any meaningful results due to paucity of publication in this subject. There were only very few papers in the English literature since 1979, which focused on this condition and were considered for this review. We have included our experience on using EIFA in late presentations of complex acetabular fractures spanning from 1999 to 2019, an experience over two decades to this report.

Results

It was observed that despite delayed presentation, good articular reduction was possible by using EIFA even in complex acetabular fractures. Ultimate functional outcomes were directly related to the accuracy of fracture reduction thus achieved. The risk of heterotrophic ossification in EIFA, though emphasized as significant in the published literature, was found to be least of a problem in our experience.

Discussion

Surgical fixation in delayed cases of complex acetabular fractures was found to be challenging. The choice of surgical approach was found to have a great bearing on the accuracy of fracture reduction and long term functional outcome. In complex acetabular fractures, despite delay in presentation, precise reduction of such fractures was found to be possible when operated using EIFA. CONCLUSION: It was concluded that Every effort must be made to reconstruct the displaced fractures of acetabulum, even in the complex types,despite when they present late, provided the fracture fits into the selection criteria described by Letournel and operated using EIFA. This is very much appropriate to younger patients, who are not great candidate for total hip replacement surgery.

Project description:BackgroundWe assessed predictive factors of patients with fractures of the lower extremities caused by trauma. We examined which factors are associated with an increased risk of failure. Furthermore, the predictive factors were set into context with other long-term outcomes, concrete pain and physical functioning.MethodsWe performed a prospective cohort study at a single level I trauma center. We enrolled patients with traumatic fractures of the lower extremities treated with internal fixation from April 2017 to July 2018. We evaluated the following predictive factors: age, gender, diabetes, smoking status, obesity, open fractures and peripheral arterial diseases. The primary outcome was time to failure (nonunion, implant failure or reposition). Secondary outcomes were pain and physical functioning measured 6 months after initial surgery. For the analysis of the primary outcome, we used a stratified (according fracture location) Cox proportional hazard regression model.ResultsWe included 204 patients. Overall, we observed failure in 33 patients (16.2 %). Most of the failures occurred within the first 3 months. Obesity and open fractures were associated with an increased risk of failure and decreased physical functioning. None of the predictors showed an association with pain. Age, female gender and smoking of more than ≥ 10 package years increased failure risk numerically but statistical uncertainty was high.ConclusionsWe found that obesity and open fractures were strongly associated with an increased risk of failure. These predictors seem promising candidates to be included in a risk prediction model and can be considered as a good start for clinical decision making across different types of fractures at the lower limbs. However, large heterogeneity regarding the other analyzed predictors suggests that "simple" models might not be adequate for a precise personalized risk estimation and that computer-based models incorporating a variety of detailed information (e.g. pattern of injury, x-ray and clinical data) and their interrelation may be required to significantly increase prediction precision.Trial registrationNCT03091114 .

Project description:BackgroundTotal hip arthroplasty (THA) is the treatment of choice for posttraumatic arthritis with failed internal fixation for hip fractures. However, the postoperative prognosis is not clear.Questions/purposesThe primary aim of the study is to report the postoperative outcome, prognosis, and complication rates of total hip arthroplasty in posttraumatic hip arthritis after failed internal fixation of fractures around the hip. The secondary aim of the study is to report results among different fracture types around the hip.Patients and methodsWe enrolled salvage THA patients after failed internal fixation of fractures around the hip and matched control patients undergoing primary THA for hip osteoarthritis. Subgroup analysis was performed to compare the postoperative outcomes, prognosis, and complication rates of salvage THA in posttraumatic hip arthritis after failed internal fixation of different fracture types around the hip.ResultsA total of 315 THAs (105 salvage THAs and 210 primary THAs) were analyzed. Patients with salvage THA had a longer operative time, lower postoperative hemoglobin (Hb) level, more Hb drop (2.2 ± 1.4 vs. 1.7 ± 1.2 gm/dl, p = 0.002), and delayed ambulation. The salvage THA group also had a higher dislocation rate within 2 months after salvage THA (9.5% vs. 1.9%, p = 0.002), reoperation rate (10.5% vs. 3.8%, p = 0.019, including debridement, open and closed reduction under sedation, revision surgery, surgical fixation for periprosthetic fractures), and revision rate (5.7% vs. 0.5%, p = 0.003) than patients undergoing primary THA. Patients who had failed fixation for acetabular fractures were younger and tended to recover well. Patients with previous intertrochanteric fracture had the longest operative time, more hip pain (83.8%, p = 0.022) and more complications.ConclusionSalvage THA in posttraumatic hip arthritis after failed internal fixation required a longer operative time and led to more blood loss and postoperative complications. The dislocation, reoperation, and revision rates after salvage THA were higher than those after primary THA. Patients with salvage THA after failed internal fixation for intertrochanteric fractures were the most susceptible to more complications compared to those with femoral neck fracture or acetabular fracture.

Project description:BackgroundIn clinical practice, acetabular posterior wall fracture combined with femoral head fracture is rare. However, with the increasing number of engineering and traffic accidents, such fractures, have increased significantly in recent years. This paper aims to explore the clinical efficiency of the Kocher-Langenbeck (K-L) and Smith-Petersen (S-P) combined approaches for open reduction and internal fixation (ORIF) of acetabular posterior wall fractures accompanied by femoral head fractures (Pipkin type IV fractures).MethodsA retrospective study was conducted on 8 patients who underwent open reduction and internal fixation (ORIF) of Pipkin type IV fractures through the K-L combined with S-P approach in our hospital from January 2015 to January 2020. All 8 patients were successfully operated on without serious complications, such as important blood vessel and nerve damage, with an operation time of 143.8 ± 44.38 min and intraoperative blood loss of 225 ± 70.71 ml. Perioperative data were recorded. The Harris score was used to evaluate the clinical effect. Fracture reduction quality was evaluated according to the Matta radiological standard. The grade of ectopic ossification was evaluated by the Brooker grading method, and the stage of femoral head necrosis was evaluated by Ficat-Arlet staging.ResultsThe Harris score increased significantly from 57.38 ± 4.779 at 3 months, to 76.13 ± 3.682 at 6 months, 88.25 ± 3.495 at 12 months, and 92.13 ± 2.232 at 36 months postoperatively. After statistical analysis, compared with the previous observation time point, the data comparison differences between the groups were statistically significant. P < 0.001, P < 0.001, P < 0.05). By the time of the latest follow-up, 6 of the 8 patients had recovered to the level of pre-injury sports capacity. In contrast, the other 2 patients remained below the level of pre-injury sports capacity. In terms of imaging evaluation, the quality of fracture reduction on radiographs was graded as excellent in 6 patients and good in 2 patients according to Matta's criteria. At the last follow-up, no heterotopic ossification or femoral head necrosis was found in of all the images. In addition, the hip joint space was normal in 6 cases, mildly narrowed in 1 case, and clearly narrowed in 1 case.ConclusionsThe K-L combined with S-P approach provides effective exposure for the reduction and fixation of Pipkin type IV fractures and achieves satisfactory clinical outcomes.
