Review Meta Analysis Comparative StudyPrimary arthrodesis versus open reduction internal fixation for acute Lisfranc injuries: a systematic review and meta-analysis.
The presence of a Lisfranc injury alone is considered a surgical indication in most patients. Indications for primary arthrodesis (PA) versus open reduction internal fixation (ORIF), however, is a topic of debate among surgeons. Conflicting data exists as to which treatment modality leads to improved patient-reported outcome measures (PROMs), reoperations, and complications. ⋯ I.

Outcome evaluation is of major importance to provide data to analyze the value of the chosen treatment concept. Despite an increasing effort of analyzing outcome after treatment of different pelvic ring injuries, a mixture of different outcome parameters is in use. The Majeed score is most frequently used for mid- to long-term evaluation and the quality of life is analyzed using the SF-36 score. ⋯ Results of treatment of specific fracture types are sparse as a wide range of different injury types and different treatment concepts are analyzed within these analyses. A sufficient pelvic outcome instrument which addresses relevant pelvic outcome parameters is still missing. Thus, future evaluation of long-term results after pelvic ring. injuries should include prospective, multicenter outcome studies with comparable parameters.

During the last two decades, extended scientific interest focused on quadrilateral plate (QLP) fractures as part of common acetabular fractures. The QLP corresponds to the medial wall of the acetabulum, and different fracture pattern of Letournel´s fracture types are associated with concomitant QLP fractures. Except anterior and posterior wall fractures, all other fracture types may be associated with QLP fractures. ⋯ Several new implants were development for optimal but often individual stabilization concepts. The gold-standard is still some medial buttressing during internal fixation predominantly using plates, but also screw fixation is considered an option. Additional dome impactions must be considered as an integral part in any QLP fracture analysis and stabilization.

Comparative Study Observational StudyComparison of two surgical treatment strategies for fragility fractures of the pelvis based on early postoperative mobility outcomes using insole force sensors.
Increasing incidences for fragility fractures of the pelvis (FFP) have been reported and surgical treatment remains demanding. While conventional screw osteosynthesis is a common method, complications may arise due to altered bone morphology in the osteoporotic pelvic bone. The iFuse implant system is a novel implant, first introduced for treatment of degenerative sacroiliac joint dysfunction, which offers promising biomechanical characteristics with potential benefits for treatment of FFP. Yet data on the use for FFP is limited. The objective of this study is to compare early postoperative mobility of patients treated with screw osteosynthesis only versus patients treated with additional iFuse stabilization based on insole force sensor gait analysis. We hypothesized that additional iFuse implantation leads to superior postoperative mobility. ⋯ Comparison of early postoperative mobility showed similar mobility outcomes in both groups. Patients with additional iFuse implantation had a more balanced gait pattern, whereas no significance was found in peak force parameters. Additional iFuse implantation showed promising results regarding patient mobility, therefore our hypothesis was partly confirmed. In future long-term examinations with larger patient cohorts should be aimed for.

Comparative StudyHow many knots are necessary to achieve knot security of two high strength suture tapes? A biomechanical comparative analysis.
According to current clinical practice, a minimum of 7 knots are required to provide secure hold in high-strength sutures. A new technology featuring a suture tape with a salt-infused silicon core has been recently developed, potentially reducing the number of needed knots. ⋯ In fatty-wet conditions-related to open surgery-the novel Dynatapetm suture tape requires 5 instead of 7 knots to achieve their security. In wet conditions-related to arthroscopic surgery-this number can be reduced to 4 knots. In contrast, the conventional SutureTapetm needs 6 knots to provide security in all conditions.
