Treating sacroiliac joint dislocation through percutaneous sacroiliac screw fixation with the aid of 2 fluoroscopes: a novel technique.

Quant Imaging Med Surg 2021 May;11(5):2076-2084

Department of Orthopedics, The Second Hospital of Jilin University, Changchun, China.

Background: Percutaneous sacroiliac screw fixation is the standard treatment for sacroiliac joint (SIJ) dislocation. In most hospitals, the procedure is guided by a C-arm X-ray fluoroscopy system, which must be repeatedly repositioned during surgery. In this study, we investigated the feasibility of using 2 fluoroscopes simultaneously. Read More

Corridor-diameter-dependent angular tolerance for safe transiliosacral screw placement: an anatomic study of 433 pelves.

Eur J Orthop Surg Traumatol 2021 Mar 1. Epub 2021 Mar 1.

Value Initiative, Minneapolis, MN, USA.

Background: The purpose of this study was to determine the angular tolerance of the S1 and S2 segments to accommodate a transiliosacral screw across both sacroiliac joints.

Hypothesis: We hypothesized that the angular tolerance for transiliosacral screw placement would be more constrained than the angular tolerance for iliosacral fixation in pelves where a safe osseous corridor was measured.

Materials And Methods: The cortical boundaries of the S1 and S2 sacral segments in 433 pelvic CTs were digitally mapped. Read More

Anatomic reduction of the sacroiliac joint in unstable pelvic ring injuries and its correlation with functional outcome.

Eur J Trauma Emerg Surg 2020 Sep 30. Epub 2020 Sep 30.

Department for Trauma Surgery, Orthopaedics and Plastic Surgery, University Medical Center Göttingen, Robert-Koch Str. 40, 37075, Göttingen, Germany.

Purpose: Reduction and percutaneous screw fixation of sacroiliac joint disruptions and sacral fractures are surgical procedures for stabilizing the posterior pelvic ring. It is unknown, however, whether smaller irregularities or the inability to achieve an anatomic reduction of the joint and the posterior pelvic ring affects the functional outcome. Here, the long-term well-being of patients with and without anatomic reduction of the posterior pelvis after sacroiliac joint disruptions is described. Read More

Posterior pelvic ring bone density with implications for percutaneous screw fixation.

Eur J Orthop Surg Traumatol 2021 Feb 9;31(2):383-389. Epub 2020 Sep 9.

Department of Orthopaedics, Rutgers New Jersey Medical School, 140 Bergen Street D Level, Newark, NJ, 07021, USA.

Background: Although the second (S2) and third (S3) sacral segments have been established as potential osseous fixation pathways for screw fixation, the S2 body has been demonstrated to have inferior bone density when compared to the body of the first (S1) sacral segment. Caution regarding the use of iliosacral screws at this level has been advised as a result. As transiliac-transsacral screws traverse the lateral cortices of the posterior pelvis, they may be relying on bone with superior density for purchase, which could obviate this concern. Read More

Computer navigation-assisted minimally invasive percutaneous screw placement for pelvic fractures.

World J Clin Cases 2020 Jun;8(12):2464-2472

Department of Orthopedics, the Second Hospital of Jilin University, Changchun 130014, Jilin Province, China.

Pelvic fractures are often caused by high-energy injuries and accompanied by hemodynamic instability. Traditional open surgery has a large amount of bleeding, which is not suitable for patients with acute pelvic fracture. Navigation-guided, percutaneous puncture-screw implantation has gradually become a preferred procedure due to its advantages, which include less trauma, faster recovery times, and less bleeding.

Biomechanical stability of sacroiliac screw osteosynthesis with and without cement augmentation.

Injury 2020 Jan 30. Epub 2020 Jan 30.

Department of General, Trauma and Reconstructive Surgery, University Hospital, LMU Munich, Marchioninistr. 15, 81377 Munich, Germany.

Background: Percutaneous sacroiliac (SI) screw fixation is the standard operative treatment of traumatic disruptions to the posterior pelvic ring. The technique offers good outcomes and early postoperative mobilization, which is vital in elderly patients with fragility fractures of the pelvis. While a double-screw technique has been shown to provide optimal biomechanical stability compared to a single-screw construct, anatomic variations and patient-specific characteristics may prevent the safe insertion of two SI screws.

A Unique "Reverse" Crescent Fragment in an Anterior-Posterior Compression Fracture: A Case Report.

JBJS Case Connect 2019 Dec;9(4):e0351

Department of Orthopaedics, University of Alabama at Birmingham, Birmingham, Alabama.

Case: We describe a patient with an anterior-posterior compression type pelvic fracture sustained after a motorcycle crash, with pubic symphysis disruption and a "reverse" crescent fragment. The injury force ruptured the anterior sacroiliac ligaments and travelled posterior medially, creating a complete Denis zone 2 sacral fracture, rather than rupturing the posterior sacroiliac ligaments as would be expected. The patient underwent open reduction and internal fixation of the pubic symphysis and closed reduction and percutaneous pinning of the right sacroiliac joint. Read More

Percutaneous screw-reinforced cement osteoplasty for palliation of postremission pain in larger lytic sacro-acetabular iliac cavities.

Radiol Case Rep 2019 Sep 12;14(9):1093-1099. Epub 2019 Jul 12.

Oncologic Radiologist, West Cancer Center and Research Institute, University of Tennessee Health Science Center, 7945 Wolf River Blvd, Germantown, TN 38138, USA.

We present 2 cases of palliative percutaneous screw fixation for refractory pain from periacetabular residual cavities, after clinical remission, from osteolytic iliac masses involving the cortices of the sacroiliac joint (SIJ). Two patients-1 with a treated 8 cm breast metastasis and another with a treated 14 cm plasmacytoma-were selected for osseous stabilization based on imaging criteria and physical signs of iliac deformability and SIJ dysfunction.

Re-examining the Spectrum of Lumbosacral Transitional Dysmorphisms: Quantifying Joint Asymmetries and Evaluating the Anatomy of Screw Fixation Corridors.

Neurospine 2020 Mar 11;17(1):294-303. Epub 2019 Jul 11.

Department of Preclinical Sciences, Faculty of Medical Sciences, The University of The West Indies, St. Augustine Campus, St. Augustine, Trinidad and Tobago.

Objective: Although a wide range of sacral dysmorphisms has been documented with lumbosacral transitional vertebrae (LSTV) variations, quantitative characterization of the upper segment morphology and articular anatomy across the array of lumbosacral transitions are hardly found in the literature. This study presents LSTV anomalies as a series of sequential morphological changes (the LSTV spectrum) and quantitatively compares 6 LSTV subtypes with normative sacral dimensions including the anatomy at the upper sacral segments used for percutaneous sacroiliac screw insertion.

Methods: Seven linear dimensions were measured from LSTV subtypes and normal sacral variants from dried adult sacral specimens. Read More
