Arthroscopic Controlled Closed Reduction and Percutaneous Fixation of Posterolateral Tibia Plateau Impression Fractures.

ABSTRACT: Posterolateral impression fractures of the tibial plateau are common, and open reduction and fixation can be demanding, including exposure of the peroneal nerve. Based on a patient example, the surgical technique of an arthroscopic controlled closed reduction and percutaneous screw fixation of a posterolateral tibia plateau impressed fracture is described. A patient sustained a posterolateral impression currently described as an "apple bite" fracture of the tibial plateau. The surgical technique includes standard arthroscopic portals and posteromedial and (transseptal) posterolateral portals. The posterolateral tibial plateau is visualized by incision of popliteomeniscal fibers, retraction of the popliteus tendon, and exposure of the posterolateral plateau. The impression area is marked with a K-wire using an anterior cruciate ligament target device. A cannulated ram is placed over the K-wire. The fracture is lifted under arthroscopic guidance and can be supported with allograft bone chips. To stabilize the reduction, 3 K-wires are positioned from anterior to posterior, and 3 cannulated screws are inserted directly under the joint surface to support the fractured area. In comparison with open surgical techniques, this procedure is exclusively performed under arthroscopic control and enables an anatomic reduction and fixation of the posterolateral tibial plateau.

Arthroscopic-assisted reduction and percutaneous fixation of tibial plateau fractures.

Project description:Tibial plateau fractures present a difficult range of fractures to treat. Arthroscopy allows for a less invasive option when compared with arthrotomy. Furthermore, visualization of the articular surface arthroscopically can allow for a precise reduction and assessment of any concomitant injuries to the articular cartilage and meniscus. By use of arthroscopy, unicondylar lateral plateaus were traditionally approached through a laterally based metaphyseal window. However, in carefully selected patients and fracture patterns, a medially based, arthroscopic-assisted approach can create long bony tunnels for subchondral support and allow for greater ease in fracture reduction. We present our technique using a medial approach for arthroscopic-assisted fixation of lateral tibial plateau fractures.

Arthroscopy Assisted Reduction Percutaneous Internal Fixation versus Open Reduction Internal Fixation for Low Energy Tibia Plateau Fractures.

Project description:The purpose of our study was to compare the curative effect of two surgical methods for Schatzker type I to III tibia plateau fractures, arthroscopy assisted reduction percutaneous internal fixation (ARIF) and open reduction internal fixation (ORIF), with the intent of evaluating the quality of evidence to assist treatment selection. Searches of PubMed, Cochrane and China National Knowledge Infrastructure (CNKI) databases were performed to identify randomized controlled trials (RCTs) and quasi-RCTs comparing ARIF and ORIF regarding the following outcomes: functional outcomes, perioperative complications and post-traumatic osteoarthritis. Odds ratios (OR) and weighted mean differences (MDs) were pooled using either a fixed-effects model or random-effects model, depending on the heterogeneity of the trials included in the analysis. 19 RCTs and one quasi-RCT provided the data from 1272 patients. ARIF was associated with better functional outcomes, a lower risk of perioperative complications, and lower risk of post-traumatic osteoarthritis. After consideration of the quality of evidence of the included studies, the advantages provided by ARIF are not substantive over ORIF for the treatment of Schatzker type I to III tibia plateau fractures, except reducing the risk of perioperative complications.

Tibial Plateau With Arthroscopic Reduction-Internal Fixation.

Project description:Arthroscopic-assisted internal fixation is an ideal technique for visualizing chondral reduction during tibial open reduction-internal fixation. Typically, open reduction-internal fixation is performed using radiographic and Fluoroscan imaging (Hologic, Bedford, MA) for reduction of subchondral bone. However, reduction without visualization does not ensure chondral surface reduction. This Technical Note and supplemental video describe an arthroscopic-assisted technique involving the tibial plateau that gives complete visualization as tamping occurs to restore the cartilage surface of the subchondral bone and elevate the fracture.

Percutaneous Reduction and Internal Fixation for Monocondylar Fractures of Tibial Plateau: A Systematic Review.

Project description:Instead of extensive dissection of soft tissue around the fracture site, percutaneous techniques have unique advantages in managing displaced fragments, including preservation of soft tissues, less blood loss, lower risk of complications, and earlier functional rehabilitation. However, there are few systematic reviews on the effects of percutaneous reduction and internal fixation (PRIF) for tibial plateau fractures. A systematic search of Cochrane, EMBASE, and MEDLINE databases was performed for all publicly available data in March 2017 regarding the use of PRIF in treating monocondylar tibial plateau fractures. Basic information of included articles, surgical information, clinical outcomes, and concomitant soft tissue injuries were collected for analysis. Finally, a total of 20 articles including 561 patients were retrieved. Traffic accident was the most common cause of injury. Percutaneous techniques using bone tamp reduction were described in all studies. The majority (≥85%) of patients were classified as excellent or good according to clinical and radiological Rasmussen scores. The overall complication rate was 6.6%, with loss of reduction the most frequent complication with an incidence of 2.4%. This systematic review indicated that PRIF was an optimal alternative that physicians should consider for the treatment of monocondylar tibial plateau fractures.

Arthroscopic Technique for Treatment of Schatzker Type III Tibia Plateau Fractures Without Fluoroscopy.

Project description:Accurate reduction and maintenance of the stability with correct implant positioning is critical for surgical treatment of tibial plateau fractures. Our technique includes an arthroscopic reduction and fixation of Schatzker type III tibial plateau fractures with a bulls-eye screw placement without fluoroscopy control. With the arthroscopic guidance, an anterior cruciate ligament drill guide is placed and a K-wire sent to the midpoint of the depressed fragment through the guide at a 40° angle to the coronal axis of the tibia. A tunnel is created with the drill over the K-wire. The depressed fragment is further augmented with gentle impacts over the K-wire. After arthroscopic reduction control, an appropriate-sized iliac graft is pushed until it is below the depressed fragment. The targeting device is adjusted at 130° so that it is parallel to the joint line and a K-wire sent through the device so that it would pass just below the graft. The graft is then supported with cannulated screws sent over the K-wire. This technique provides an arthroscopic reduction of the chondral surface and precise placement of the rafting screws without fluoroscopy.

ORV Arthroscopic Reduction and Internal Fixation of Tibial Eminence Fractures.

Project description:Tibial eminence fractures are an uncommon but well-described avulsion of the anterior cruciate ligament. Treatment principles are based on the amount and pattern of fracture displacement. Management has evolved from closed reduction and immobilization to arthroscopic reduction and internal fixation followed by early rehabilitation. Various fixation methods have evolved, ranging from arthroscopic reduction and percutaneous screw fixation to arthroscopic suture repair. We present a technique for arthroscopic reduction and internal fixation using a cannulated drill bit and high-strength suture. This technique facilitates anatomic reduction with uncomplicated tunnel placement and suture passing in an effort to allow strong fixation and early rehabilitation.

Arthroscopy-assisted closed reduction and percutaneous nail fixation of unstable ankle fractures: description of a minimally invasive procedure.

Project description:When one is surgically managing an unstable ankle fracture, anatomic reduction of the syndesmosis is typically accomplished using an open surgical approach. We propose an arthroscopically assisted technique that restores normal anatomy while using a percutaneously placed intramedullary nail to fix the fibula. The patient is positioned supine, and the ankle is placed under traction by use of a tensor bandage. Standard anteromedial and anterolateral arthroscopy portals are used. The joint is examined for bony, ligamentous, and chondral injury. Lateral malleolus fracture reduction is accomplished with pointed reduction forceps to apply traction and rotation to the tip of the distal fibula fragment. A retrograde fibular intramedullary nail (Acumed, Hillsboro, OR) is inserted under fluoroscopic guidance. Arthroscopy is then used to guide the reduction of the fibula and rotation of the fibula with placement of the arthroscope in the lateral gutter. Syndesmosis screws are placed once the fracture and syndesmosis reductions are confirmed through both fluoroscopy and arthroscopy.

Arthroscopic Assisted Reduction and Internal Fixation of Tibial Plateau Fractures by Viewing and Instrumentation Access Through Coexisting Meniscus Tear: Case Series.

Project description:Meniscus tear coexisting with tibial plateau fractures may be found in 2-49% of cases. Literature accepts that torn meniscus can be retracted towards the center to improve visualization of the peripheral plateau which is ordinarily concealed by the overlying meniscus. We hypothesized that easing in microscope through a coexisting tear may be much less disruptive with little or no adverse effects with respect to either the propagation of tear or its later repair. This strategy improved visualization as well as the extended reach of interventional instrumentation access to otherwise concealed areas of plateau and endoscopic trans-focal access to a vertical limb of fracture split on the anterior cortex of proximal tibia without any impact on the stability of repaired meniscus. The experience in a series of six cases is shared.Supplementary informationThe online version contains supplementary material available at 10.1007/s43465-022-00703-7.
