Highly impacted bone allograft may allow immediate weight bearing in tibial plateau fractures: A case report.

ABSTRACT: Introduction:Proximal tibial fractures are common with an incidence of 10.2/100.000. Those displaced and involving the articular surface will often require surgical treatment. However, no consensus exists on whether to allow the patient early weight bearing or not. We developed a technique using structural bone chips, highly impacted under the articular surface, to permit immediate weight bearing after surgery. Patient:The patient was a 44-year old male who suffered a lateral tibial plateau fracture (AO type 41B2). Intervention:We used an anterolateral approach with an S-shaped incision. A small window in the tibia was made using an awl, and the articular surface was reduced under radiographic imaging. The bone allograft was prepared by splitting the frozen femoral head in quarters and then taking large pieces of bone with a bone rongeur forceps avoiding the cartilage. The large pieces of bone were gathered in a small tray and thereafter compressed into the drill guide insert. The drill guide filled with bone graft was then inserted into the tibia window and directed in the appropriate position guided by radiography. Hereafter, the bone graft was impacted under the articular surface with force using the appropriate trocar and a hammer, and the fracture was finally reduced. Finally, the fracture was fixated utilizing an angular stable plate. Outcome:The patient was followed up one year postoperatively and allowed immediate weight bearing after surgery. No subsequent articular collapse occurred. Discussion:In this case, we present a proximal tibial fracture with articular depression, which was surgically treated with a highly impacted bone allograft of large pieces and a locking plate. The patient was allowed immediate weight bearing and no subsequent articular collapse occurred.

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.

Project description:To systemically review all studies reporting return to sport following tibial plateau fracture, in order to provide information on return rates and times to sport, and to assess variations in sporting outcome for different treatment methods.A systematic search of CINAHAL, Cochrane, EMBASE, Google Scholar, MEDLINE, PEDro, Scopus, SPORTDiscus and Web of Science was performed in January 2017 using the keywords "tibial", "plateau", "fractures", "knee", "athletes", "sports", "non-operative", "conservative", "operative", "return to sport". All studies which recorded return rates and times to sport following tibial plateau fractures were included.Twenty-seven studies were included: 1 was a randomised controlled trial, 7 were prospective cohort studies, 16 were retrospective cohort studies, 3 were case series. One study reported on the outcome of conservative management (n = 3); 27 reported on the outcome of surgical management (n = 917). Nine studies reported on Open Reduction Internal Fixation (ORIF) (n = 193), 11 on Arthroscopic-Assisted Reduction Internal Fixation (ARIF) (n = 253) and 7 on Frame-Assisted Fixation (FRAME) (n = 262). All studies recorded "return to sport" rates. Only one study recorded a "return to sport" time. The return rate to sport for the total cohort was 70%. For the conservatively-managed fractures, the return rate was 100%. For the surgically-managed fractures, the return rate was 70%. For fractures managed with ORIF, the return rate was 60%. For fractures managed with ARIF, the return rate was 83%. For fractures managed with FRAME was 52%. The return rate for ARIF was found to be significantly greater than that for ORIF (OR 3.22, 95%CI: 2.09-4.97, P < 0.001) and for FRAME (OR 4.33, 95%CI: 2.89-6.50, P < 0.001). No difference was found between the return rates for ORIF and FRAME (OR 1.35, 95%CI: 0.92-1.96, P = 0.122). The recorded return time was 6.9 mo (median), from a study reporting on ORIF.Return rates to sport for tibial plateau fractures remain limited compared to other fractures. ARIF provides the best return rates. There is limited data regarding return times to sport. Further research is required to determine return times to sport, and to improve return rates to sport, through treatment and rehabilitation optimisation.
