All-Arthroscopic Treatment of Schatzker Type III Lateral Tibial Plateau Fracture Without Fluoroscopy.

ABSTRACT: Tibial plateau fracture treatment remains challenging for orthopaedic surgeons around the world, especially in case of type III fractures according to the Schatzker classification, which are a pure depression of the lateral tibial plateau. Whereas open surgical procedures are associated with increased soft-tissue trauma because of the extent of the surgical approach and do not always allow for proper visualization of the fracture site, arthroscopic-assisted surgeries have been proven to have benefits over the former in terms of minimizing soft-tissue trauma, improved visual control of the fracture reduction, and the time of recovery. Most arthroscopic techniques, however, require using fluoroscopy. We present an all-arthroscopic procedure for Schatzker type III lateral tibial plateau fractures with using a trans-septal portal for visualization, which does not demand fluoroscopy.

Project description:The most commonly accepted system of classification for tibia plateau fractures is that of Schatzker. Increasingly, both high energy injuries and atypical osteoporotic fragility failures have led to more complex, unusual and previously undescribed fracture patterns being recognized. We present a case of a patient with a previously unreported pattern of tibia plateau fracture and knee dislocation. We highlight the challenges confronted and present the management and the outcomes of his injury. A 28-year old male motorcyclist was involved in a head on collision with a truck and was transferred by helicopter to our level 1 major trauma centre emergency department. His injuries were a circumferential degloving injury to his left leg and a right lateral tibial plateau fracture/knee dislocation. The pattern of the lateral tibial plateau fracture was unique and did not fit any recognised classification system. The patient received a spanning external fixator initially and after latency of 12 days for soft tissue resuscitation he underwent definite fixation through an antero-lateral approach to the proximal tibia with two cannulated 6.5 mm partially threaded screws and an additional lateral proximal tibia plate in buttress mode. A hinged knee brace was applied with unrestricted range of motion post-operatively and free weight bearing were permitted post operatively. At the 6 months follow up, the patient walks without aids and with no limp. Examination revealed a stable joint and full range of motion. Plain radiographs revealed that the fracture healed with good alignment and the fixation remained stable. High energy injuries can lead to more complicated fracture patterns, which challenge the orthopaedic surgeons in their management. It is crucial to understand the individual fracture pattern and the possible challenges that may occur. This study reports a lateral tibia plateau fracture/dislocation which perhaps is best described as a reverse Schatzker IV type fracture.

Project description:PurposeTo examine the condition and triggers of stress fractures of the lateral tibial plateau (LTP) similar to type III lateral hinge fractures (LHFs) after open wedge high tibial osteotomy (OWHTO).MethodsOWHTO was performed in 118 knees. They were examined for LHFs by computed tomography (CT). Patients were divided into the stress fracture group (Group SF) if they showed fracture lines on CT performed after starting weight-bearing walking and the normal group (Group N) for others.ResultsThe mean age was significantly older in Group SF (P?=?0.022). Preoperatively, Group SF showed a significantly higher tibio-femoral angle (TFA, P?=?0.014). No significant differences were observed in TFA and weight-bearing line ratio after surgery. Correction angle was significantly higher in the SF group. And all of the SF were more than 13 degrees. There was no significant difference in LHF incidence between groups, whereas stress fracture incidence differed significantly for each type of LHF (chi-squared test, P?=?0.0001): 14.6% of type I cases, 100% of type II cases, 0% of type III cases, and 6.1% of those without LHF.DiscussionThe load on the LTP is assumed to act as a shearing force in type II fractures, which may contribute greatly to stress fractures. In type III, stress fractures may not occur because of the load dispersed at the fracture part. The stress fracture site is similar to type III LHF, and this kind of fracture is thought to be a delayed type III because it occurs after patients start weight-bearing walking. Moreover, they are observed in type I cases with a stable hinge and in 6% of cases without LHF. This study showed that high varus knees corrected with a large correction angle may develop stress fractures. OWHTO requires attention to stress fractures of the LTP, which can be regarded as delayed type III, in those developing LHFs postoperatively or having a high varus knee preoperatively.ConclusionThese results indicated the possibility of stress fracture in LTP during weight-bearing exercise after OWHTO, which was regarded as a delayed type III fracture. The results showed that Correction angle was more than 13 degrees, and lateral hinge fracture type II of the Takeuchi classification was an inducement of this stress fracture.Level of evidenceLevel IV.
