Achieve Closed Reduction of Irreducible, Unilateral Vertically Displaced Pelvic Ring Disruption with an Unlocking Closed Reduction Technique

Abstract

Objective To be able to treat irreducible unilateral vertically displaced pelvic ring disruption (UVDPRD) using closed reduction, we introduced a technique named Unlocking Closed Reduction Technique (UCRT) and evaluated its effectiveness with improved pelvic closed reduction system (PCRS). Methods A retrospective study was performed in our department. Between January 2014 and December 2017, 43 patients whose UVDPRD were not successfully reduced using transcondylar traction. Subsequently, they were treated with UCRT using improved PCRS. The study included 19 male and 24 female patients, with a mean age at the time of the operation of 46.2 years. During surgery, operation time and blood loss were recorded. Post‐surgical reduction quality was evaluated using Matta scoring criteria and patient lower‐extremity functional outcome was evaluated using Majeed functional scoring criteria. Results When used with improved PCRS, UCRT achieved pelvic reduction in all 43 cases of irreducible UVDPRD with postoperative pelvic reduction quality rated excellent and good for 42/43 (97.6%) patients according to the Matta scoring criteria (Matta Score < 10 mm). While no post‐surgical complications emerged as the direct result of UCRT in this cohort of patients, 8/37 patients who were treated with subcutaneous supra‐acetabular pedicle screw internal fixation (INFIX) for anterior ring fixation developed lateral femoral cutaneous nerve injury but recovered 6 months postoperatively. No revision surgery was performed on any of the recruited patients. All patients' lower‐extremity functionality was rated excellent with an average Majeed function score of 94.3 during the last follow‐up at an average of 41.6 months postoperatively. Conclusion With excellent surgical and functional outcomes in patients with irreducible UVDPRD, improved PCRS‐assisted UCRT proved to be a safe and effective method for the treatment of irreducible UVDPRD.

Lateral Compression Type 2 Pelvic Fractures—A Clinical Study of Fracture Displacement Measurement and Closed Reduction

“…Step 3: After the above preparations were completed, the reduction of the fracture began. 13 Abridged general view showed the two different closed reduction strategies for two different types of posterior ring injuries (Figure 2 ).…”

Gradual Traction Reduction With the Ilizarov Method for Tile C1.2 Old Pelvic Fracture

“…Therefore, it is necessary to release and unlock the sacroiliac joint before attempting closed reduction. Researchers used a closed unlocking reduction technique for Tile C pelvic fractures, and postoperative pelvic reduction quality was excellent or good among 97.6% of the patients 25 . The key to the closed unlocking reduction technique is to unlock the sacroiliac joint by lateral traction.…”

Autonomous path planning for robot‐assisted pelvic fracture closed reduction with collision avoidance

“…Therefore, its closed reduction path planning is challenging and currently limited to linear planning. Severe pelvic fractures have both position and orientation deviation and even spatial overlap, making simple linear planning inappropriate 9,10 . Previous papers have widely reported the path planning methods for robot‐assisted lower‐extremity fracture closed reduction (RLFCR).…”

This paper developed an RPFCR path-planning algorithm by summarising and improving the RLFCR path-planning methods.…”
