Outcome of alternative approach to displaced acetabular fractures

Tratamento de fraturas acetabulares de duas colunas por dupla via extrapélvica: 3 casos clínicos

As fraturas de duas colunas do acetábulo segundo a classificação de Letournel são das mais comuns em frequência, indicação e complexidade cirúrgica. Estas resultam essencialmente de mecanismos de compressão lateral e caracterizam-se por originarem um acetábulo desconectado do esqueleto axial. O seu tratamento cirúrgico pode incluir: abordagem anterior ou posterior isolada; combinadas, no mesmo tempo cirúrgico ou não; ou abordagens alargadas. Os autores apresentam outra opção cirúrgica com associação de via de Kocher-Langenbeck e abordagem da crista ilíaca simultânea e no mesmo posicionamento (decúbito lateral) com base nos três primeiros casos clínicos realizados e seus resultados clínicos e imagiológicos. Para além da apresentação dos casos, é feita uma descrição dos três fragmentos característicos deste tipo de fraturas acetabulares, da via de abordagem e da sequência de redução realizada. Pelos resultados obtidos e vantagens associadas, os autores acreditam que a adição da abordagem da crista ilíaca à via de Kocher-Langenbeck pode ser uma opção muito atrativa a ter em conta no tratamento cirúrgico de fraturas de duas colunas do acetábulo devidamente selecionadas.

Meta-analysis of modified Stoppa approach and ilioinguinal approach in anterior pelvic ring and acetabular fractures

BACKGROUND

The purpose of this meta-analysis was to compare the efficacy of the modified Stoppa approach (MSA) and ilioinguinal approach (IA) in the treatment of anterior pelvic ring and acetabular fractures.

METHODS

A literature search was conducted using PubMed, Embase, and Cochrane database for articles that compared MSA and IA in the treatment of anterior pelvic ring and acetabular fractures. All the included articles were evaluated by 2 trained reviewers in accordance with the Cochrane Collaboration Handbook for potential risk. The Jadad decision algorithm and Downs and Black scores were also used to assess the quality of the included studies. The extracted data included operative time, intraoperative blood loss, reduction quality, clinical outcome, and complications.

RESULTS

Five articles were included in this meta-analysis, with 186 patients in the MSA group and 219 patients in the IA group. Compared with IA, MSA significantly shortened the operative time (P = .0002), decreased intraoperative blood loss (P = .002), and provided better reduction quality (P = .03). Meanwhile, this meta-analysis suggests no significant difference between MSA and IA regarding clinical outcomes (P = .63) and complications (P = .34). The subgroup analysis of complications also showed no statistically significant difference between the 2 groups (including infection, and vascular and nerve injuries).

CONCLUSION

According to this meta-analysis, the currently available evidence suggests that MSA can significantly shorten operative time, decrease intraoperative blood loss, and provide better reduction quality than IA in the treatment of anterior pelvic ring and acetabular fractures. In addition, in terms of clinical outcomes and complications, no significant differences were found between the 2 groups.

LEVEL OF EVIDENCE

Level IV, meta-analysis.

3D surgical printing for preoperative planning of trabecular augments in acetabular fracture sequel

We describe the methodical and possibilities of 3D surgical printing in preoperative planning for a total hip arthroplasty in acetabular deformity after acetabular fractures, showing a case of a 43-year-old with posttraumatic arthritis after both column fracture of the left acetabulum that was treated non operatively, supporting the do it yourself mode.
