Arthroscopic assistance during open reduction and fixation for complex acetabular fractures

Achieving an anatomical reduction in acetabular fracture is essential but may also be challenging. Most of complex fractures are treated with anterior approaches without direct visualization of the acetabular surface. In this paper, we present the surgical technique for arthroscopic assistance during open reduction and fixation for complex acetabular fractures. To our knowledge, this technique has not been described in the literature yet.

Arthroscopy-Assisted Reduction and Fixation of Femoral Head and Acetabulum Fractures: A Systematic Review of the Literature

Objective

To perform a systematic review to determine the current arthroscopic techniques of the fixation of femoral head and acetabulum fractures and assess the radiological and functional outcomes reported in literature written in English.

Methods

This review was performed by searching PubMed, Cochrane Library, Scopus, and Web of Science without a filter for time limitation in line with Preferred Reporting Items for Systematic Reviews Protocols (PRISMA‐P) guidelines. Two authors took part in screening and evaluating the literature between December 2020 and January 2021. The terms acetabulum fracture, reduction, fixation, femur head fracture, fracture dislocation of the hip, hip trauma and arthroscopy or arthroscopic, and their combinations were used to search four database engines in the titles and abstracts of the reported papers. Only papers with English titles and abstracts were included. The assessment of the data related to descriptions of the techniques, indications for fracture fixation using arthroscopy, and patient‐related outcomes.

Results

Perfect agreement was detected between the two reviewers during all steps of the review process (κ = 0.81–1.00). Although a meta‐analysis was planned to be carried out, no randomized controlled study comparing either the radiological or functional results of different surgical techniques was detected in the literature. Nineteen studies were included in the study. Of these, 15 were retrospective case reports and four were case series. Twenty‐seven patients were operated on for acetabulum fractures (18 male/nine female). The mean age was 28.3 years (range, 15–53 years). High‐energy traumas including motor vehicle accidents were the most common reason (81%). The duration of follow‐up was a mean of 32 months (range, 12–68 months). Sixteen patients were operated on for femur fractures (12 male/three female). The mean age was 30.1 years (range, 17–50 years). Motor vehicle accident was the most common trauma (70%). Duration of follow‐up had a mean of 18 months (range, 4–60 months). Patient‐related outcomes were excellent for reported cases in both groups despite the fact that an objective scoring system was not used for most of the cases. Moreover, there was no consensus on surgical indications or the techniques.

Conclusions

The techniques of arthroscopic‐assisted fixation of acetabulum and femoral head fracture are so heterogeneous that conclusions cannot be made at this time, but there is potential for this method of treatment to become more popular as the devices used in the procedure develop and as exposure to and experience with hip arthroscopy improves. Further descriptions of reduction and fixation techniques and analysis of outcomes of RCTs are needed.

Hip Arthroscopy in Trauma: A Systematic Review of Indications, Efficacy, and Complications

PURPOSE

This systematic review explored the indications, efficacy, and complications of hip arthroscopy in the setting of trauma.

METHODS

Databases (PubMed, Medline, Embase, and Web of Science) were searched from database inception to March 2015 for studies using hip arthroscopy in trauma treatment. Systematic screening of eligible studies was undertaken in duplicate. The inclusion criteria included studies pertaining to arthroscopic intervention of all traumatic hip injuries. Abstracted data were organized in table format with descriptive statistics presented.

RESULTS

From an initial search yield of 2,809 studies, 32 studies (25 case reports and 7 case series) satisfied the criteria for inclusion. A total of 144 patients (age range, 10 to 53 years) underwent hip arthroscopy for 6 indications associated with trauma: 8 patients for bullet extraction, 6 for femoral head fixation, 82 for loose body removal, 6 for acetabular fracture fixation, 20 for labral intervention, and 23 for ligamentum teres debridement. Patients were followed up postoperatively for a mean of 2.9 years (range, 8 days to 16 years). Successful surgery was achieved in 96% of patients. The rate of major complications (i.e., pulmonary embolism and abdominal compartment syndrome) was 1.4% (2 of 144); avascular necrosis, 1.4% (2 of 144); and nerve palsy, 0.7% (1 of 144).

CONCLUSIONS

Hip arthroscopy appears effective and safe in the setting of trauma. These data should be interpreted with caution because of the low-quality evidence of the included studies. Surgeons should be aware of the potential complications such as abdominal compartment syndrome and thromboembolic events when performing hip arthroscopy in the setting of trauma.

LEVEL OF EVIDENCE

Level IV, systematic review of Level IV studies.

Current possibilities for hip arthroplasty

Hip arthroscopy has been popularized over the last decade and, with technical advances regarding imaging diagnostics, understanding of the physiopathology or surgical techniques, several applications have been described. Both arthroscopy for intra-articular conditions and endoscopy for extra-articular procedures can be used in diagnosing or treating different conditions. This updated article has the objective of presenting the various current possibilities for hip arthroscopy.
