Multifragmentary patellar fracture has a distinct fracture pattern which makes coronal split, inferior pole, or satellite fragments.

ABSTRACT: The present study aimed to map the location and frequency of fracture lines on the coronal articular and sagittal planes in multifragmentary patellar fractures. 66 multifragmentary patellar fractures were digitally reconstructed using the 3D CT mapping technique. The coronal articular surface and midsagittal fracture maps were produced by superimposing each case over a single template. Each fracture line was classified based on the initial displacement and orientation. We evaluated the frequency and direction of the fracture line, coronal split fragment area, and satellite and inferior pole fragment presence. Coronal articular surface fracture mapping identified primary horizontal fracture lines between the middle and inferior one-third of the articular surface in 63 patients (95.4%). Secondary horizontal fracture lines running on the inferior border of the articular facet were confirmed (83.3%). Secondary vertical fracture lines creating satellite fragments were mostly located on the periphery of the bilateral facet. Midsagittal fracture mapping of primary and secondary horizontal fracture lines with the main coronal fracture line revealed a predominantly X-shaped fracture map. The consequent coronal split fragment and inferior pole fracture were combined in most cases. In conclusion, the multifragmentary patellar fracture has a distinct pattern which makes coronal split, inferior pole, or satellite fragments.

Tension band wiring versus suture anchor technique in patellar inferior pole fracture: Novel double row suture anchor technique.

Project description:IntroductionPatellar inferior pole fractures are challenging to obtain sufficient fixation. The purpose of this retrospective, case-controlled study was to compare the clinical and radiological outcomes between tension band wiring (TBW) and our novel double-row suture anchor (SA) technique in patellar inferior pole fractures.Materials and methodsThis retrospective study included patients who underwent TBW or SA fixation for patellar inferior pole fractures from 2015 to 2019. A total of 63 patients were divided into two groups according to the surgical procedure: the TBW group (n = 35) and the SA fixation group (n = 28). The visual analog scale score, range of motion of the knee, Lysholm score, Kujala patellofemoral score, and patient satisfaction score were evaluated for clinical and functional outcomes. Radiological outcomes included the time to radiological union, loss of reduction, and the Insall-Salvati (IS) ratio.ResultsSignificant improvements in clinical outcomes were observed in both groups with no significant differences. Bone union was achieved in all patients, and there was no significant difference in the time to radiological union and the IS ratio between the two groups. All patients in the TBW group underwent additional surgeries for implant removal. However, none of the patients in the SA group underwent implant removal or experienced skin irritation.ConclusionOur novel double-row SA technique could provide comparable fixation strength and good clinical outcomes, with fewer complications in patellar inferior pole fractures. This novel SA technique is a satisfactory alternative treatment for patellar inferior pole fractures.

Candy box technique for the fixation of inferior pole patellar fractures: finite element analysis and biomechanical experiments.

Project description:BackgroundMaintaining effective reduction and firm fixation in inferior pole patellar fractures is a highly challenging task. There are various treatment methods available; although tension-band wiring combined with cerclage wiring (TBWC) is the mainstream approach, its effectiveness is limited. Herein, we propose and evaluate a new technique called candy box (CB), based on separate vertical wiring (SVW), for the treatment of inferior pole patellar fractures. Specifically, we provide biomechanical evidence for its clinical application.MethodsFive fixation models were built: SVW combined with cerclage wiring (SVWC); TBWC; modified SVW with the middle (MSVW-A) or upper (MSVW-B) 1/3 of the steel wire reserved, and CB. A finite element analysis was performed to compare the displacement and stress under 100-N, 200-N, 300-N, 400-N and 500-N force loads. Three-dimensional printing technology was utilized to create fracture models, and the average displacement of each model group was compared under a 500-N force.ResultsThe results of the finite element analysis indicate that CB technology exhibits significantly lower maximum displacement, bone stress, and wire stress compared to that with other technologies under different loads. Additionally, in biomechanical experiments, the average force displacement in the CB group was significantly smaller than that with other methods under a 500-N force (P < 0.05).ConclusionsCB technology has the potential to overcome the limitations of current techniques due to its superior biomechanical characteristics. By incorporating early functional exercise and ensuring strong internal fixation, patient prognosis could be enhanced. However, further clinical trials are needed to fully evaluate the therapeutic effects of CB technology.

Paediatric conjoint bicondylar Hoffa fracture with patellar tendon injury: An unusual pattern of injury.

Project description:Epiphyseal injuries of distal femur are rare with an incidence of 1%-6% among all physeal injuries. Prompt diagnosis and appropriate surgical treatment is crucial to achieve satisfactory functional outcomes. A conjoint bicondylar coronal split (Hoffa) fracture with complete transaction of ipsilateral patellar tendon has been reported in a 12 year old child. The injury was managed by open reduction and internal fixation and bone to tendon repair. This case emphasizes the need of accurate intraepiphyseal fixation for the management of these fractures in skeletally immature patients.

Fracture of an uncemented tantalum patellar component.

Project description:A 62-year-old man presented with the acute, atraumatic onset of pain 3 years after uncemented right total knee arthroplasty. He complained of new mechanical locking with the knee held in extension on examination and unable to flex the knee. On the plain radiographs, the patellar component peg was fractured and the plate was dislocated. The knee was immobilized, and revision to a cemented 3-peg component was performed. Fracture of a single-peg, tantalum-backed uncemented patellar component has not been described. Clinical suspicion for this should be given in the setting of acute locking. We recommend revision with a cemented polyethylene component.

Patellar Fracture Fixation Using Suture Tape Cerclage.

Project description:Transverse patellar fractures are a relatively common injury and typically require surgical fixation. An adequate restoration of patella integrity is essential for proper functioning of the extensor mechanism of the knee and for the prevention of patellofemoral osteoarthritis. Currently, the treatment of transverse fractures of the patellar bone involves several surgical techniques, most of which involve the use of metallic implants. Despite good clinical results following surgery, numerous complications exist, including primarily symptomatic hardware following surgical treatment. The purpose of this article is to describe the technique for treatment of a transverse patellar fracture using a high-resistance tape (FiberTape; Arthrex) and a tensioner (Arthrex) instead of traditional metallic implants.

Transoral unilateral lag screw osteosynthesis for coronal split fracture of the lateral mass of the atlas - case report, operative technique and review of the literature.

Project description:IntroductionAtlas ring fractures, which account for 1.3% of all spinal fractures, are predominantly managed conservatively. However, in certain cases, surgical treatment may be necessary depending on the type of fracture, degree of comminution, fracture location, and associated ligamentous injuries. Surgical stabilization frequently results in a posterior C1-2 or C0-2 fusion, which restricts movement, particularly craniocervical rotation. Coronal split fractures of the lateral mass need to be reduced and fixed due to dislocation, instability and secondary osteoarthritis. The preferred treatment approach involves internal fixation of the reduced fracture fragments, while avoiding restriction of the upper cervical spine's range of motion (ROM).Research questionIs unilateral anterior transoral lag screw for treatment of unstable coronal split fracture of lateral mass of the atlas feasible and a safe treatment option?Case report material and methodsWe report on a 55-year-old female suffering from polytrauma with multiple spinal and extremity injuries.ResultsA coronal split fracture of the lateral mass of the atlas was treated minimally invasive with a transoral lag screw technique to reduce and fix the fracture that has a tendency for fracture gap widening. Stable fixation and fracture union and thus restoration of function was achieved.Discussion and conclusionTransoral lag screw osteosynthesis for coronal split fracture of the lateral mass of the atlas is a potential treatment option in selected cases to preserve mobility in the upper cervical spine after spinal trauma.

Coronal-splitting Reduction Genioplasty Combined with Bilateral Osteotomies of the Mandibular Inferior Border for Macrogenia.

Project description:There are various types of chin deformities, and the least established surgical method for deformity correction may be reduction for anteroposterior macrogenia. Anteroposterior macrogenia is commonly corrected by either setback genioplasty or burring reduction, but these approaches are less likely to produce aesthetically pleasing results. Both procedures have poor reduction effects because of the low response rate of soft tissues to skeletal alterations. There is a high likelihood of chin ptosis and flattening. Setback genioplasty can also yield step deformities at the inferior mandibular border. To overcome these drawbacks of conventional methods, I developed a novel technique of coronal-splitting reduction genioplasty. I have performed more than 83 procedures with a high success rate over the past 10 years. Alloplastic chin implant-shaped bone fragments were resected from the prominent bony chin, in which the average thickness of resected bone was 8.2 mm. Sufficient sagittal reduction effects were then achieved in most cases, although the soft tissue response rate remains 25%-50%, as reported in the literature. The no-degloving technique with cephalic suspension of the mentalis muscle prevents chin ptosis. Combined bilateral oblique osteotomies of the inferior mandibular border contribute to minimizing obvious postoperative chin flattening. Moreover, macrogenia can be large in multiple planes, including anteroposterior, vertical, transverse, or their combinations. This new technique can handle all three planes by combining both bilateral oblique osteotomies of the inferior mandibular border and burr ostectomy. Overall, these findings suggest that the coronal-splitting genioplasty method may replace conventional methods for correcting macrogenia.

Patellar Fracture Fixation With Cannulated Compression Screws and FiberTape Cerclage.

Project description:Transverse patella fractures with loss of knee extensor mechanism function are a common orthopaedic injury requiring operative fixation. Current accepted surgical options for noncomminuted transverse fractures include open reduction with tension band wiring. Although these procedures result in good clinical outcomes and fracture healing, symptomatic hardware from the historically used metal implants is very common. The purpose of this Technical Note is to describe a technique for treatment of transverse patellar fractures using cannulated compression screws with tensioned high-resistance suture tape functioning as the tension band. This technique provides effective, reproducible fracture fixation while minimizing symptomatic hardware, failure, and reoperation.

Biodegradable magnesium pins enhanced the healing of transverse patellar fracture in rabbits.

Project description:Displaced fractures of patella often require open reduction surgery and internal fixation to restore the extensor continuity and articular congruity. Fracture fixation with biodegradable magnesium (Mg) pins enhanced fracture healing. We hypothesized that fixation with Mg pins and their degradation over time would enhance healing of patellar fracture radiologically, mechanically, and histologically. Transverse patellar fracture surgery was performed on thirty-two 18-weeks old female New Zealand White Rabbits. The fracture was fixed with a pin made of stainless steel or pure Mg, and a figure-of-eight stainless steel band wire. Samples were harvested at week 8 or 12, and assessed with microCT, tensile testing, microindentation, and histology. Microarchitectural analysis showed that Mg group showed 12% higher in the ratio of bone volume to tissue volume at week 8, and 38.4% higher of bone volume at week 12. Tensile testing showed that the failure load and stiffness of Mg group were 66.9% and 104% higher than the control group at week 8, respectively. At week 12, Mg group was 60.8% higher in ultimate strength than the control group. Microindentation showed that, compared to the Control group, Mg group showed 49.9% higher Vickers hardness and 31% higher elastic modulus at week 8 and 12, respectively. At week 12, the new bone of Mg group remodelled to laminar bone, but those of the control group remained woven bone-like. Fixation of transverse patellar fracture with Mg pins and its degradation enhanced new bone formation and mechanical properties of the repaired patella compared to the Control group.

A case report of patellar fracture treated by percutaneous strong suture technique.

Project description:Tension-band wiring with metal such as Kirshner wire or soft steel wire is commonly used for the treatment of patellar fractures. In recent years, metal-free surgery using a strong suture with high breaking strength has been reported to have excellent outcomes. We report a case of patellar fracture treated with a minimally invasive percutaneous strong suture. The patient is a 57-year-old salesman who fell at work, hit his knee, and came to our hospital complaining of pain. His range of motion was -15° in extension and 60° in flexion. His X-ray results showed a transverse fracture of the right patella with a 3-mm displacement, and surgery was performed 7 days post-injury. A small incision of 1 cm was made distally and proximally on the patella. Two 2.0-mm perforated K-wires were inserted from distal to proximal sides, and the wire was pulled out proximally with FiberWire® No. 2. The distal end of the FiberWire was pulled through the proximal incision via the anterior surface of the patella and finally fastened. The procedure was completed in 21 min. The patient did not use a brace since the operation day and was not restricted in terms of load or range of motion. He was able to walk without any assistance after 10 days and returned to driving and office work 14 days postoperatively. At the final follow-up, no symptoms of skin irritation were detected, and the patient did not require suture removal.
