An attempt to treat Hoffa fractures under arthroscopy: A case report

We treated a 15-year-old female patient with fracture of the post-lateral femoral condyle and the bone shifted in front of the knee. Considering that the traditional surgical approach has the shortcomings of significant trauma and poor prognosis, we designed an arthroscopic procedure, which achieved satisfactory short-term efficacy, effectively reduced and fixed the fractures, avoided damage to vascular nerves, and maximally reduced the trauma caused by surgery itself.     

Plate fixation for Letenneur type I Hoffa fracture: a biomechanical study

BackgroundA coronal fracture of the posterior femoral condyle, also known as a Hoffa fracture, is an unusual injury, and there are only a handful of case reports or series exploring it. The optimal fixation method of these intraarticular fractures remains controversial; improper or unstable fixation usually lead to an unsatisfactory prognosis. The use of posterior–anterior or reversed lag screw fixation is still a popular method. Additional buttress plating is also recommended for fixation of these difficult fractures. The purpose of this study was to compare the mechanical strength of four different fixation patterns for this uncommon fracture.Material and methodsSixteen sawbone simulated models of Letenneur type I Hoffa fractures were created with one of four fixation patterns: two screws implanted in the anterior–posterior (AP) direction or posterior–anterior (PA) direction; one screw in the PA direction with a plate implanted in the posterior position of the distal femoral condyle or with a plate in the lateral position. Biomechanical testing was performed to determine the post-fixation axial stiffness, the maximum load to failure and the fragment vertical displacement for each of the four constructs.ResultsThe plate fixation patterns whether implanted in the posterior or lateral position were shown to provide higher overall axial stiffness and load to failure, and less vertical displacement than the other two patterns of pure screw fixation. Among these constructs, the lateral plate fixation was found to provide the highest stiffness and load to failure and the least displacement for the posterior condylar fragments, followed by the posterior plate fixation. The lowest overall stiffness and load to failure and the largest vertical displacement were found in the construct with the AP direction placed screws.ConclusionIt was concluded that the lateral position implanted plate is biomechanically the strongest fixation method for Letenneur type I Hoffa fractures. However, this plate fixation is not recommended for all cases. The choice of internal fixation pattern depends on the surgeons.

目的比较不同内固定方式对踝关节骨折的疗效,以期为临床提供依据。方法回顾性分析治疗的踝关节骨折患者38例,其中接受闭合复位内固定手术的患者22例,设为闭合复位组;接受传统切开复位内固定手术的患者16例,设为切开复位组。术后对患者进行随访,比较两组患者治疗优良率及术后并发症发生率。结果闭合复位组患者术后优良率86.36%(19/22),并发症发生率9.09%(2/22);切开复位组术后优良率为75%(12/16),并发症发生率为18.75%(3/16)。闭合复位组治疗优良率显著高于切开复位组,闭合复位组并发症发生率显著低于切开复位组,两组比较差异有统计学意义(P0.05)。结论与传统的切开复位内固定术相比,闭合复位经皮空心螺钉内固定法能够有效提升治疗效果并减少并发症发生率,减轻患者负担、提高患者生存质量,值得在临床上推广应用。     

Coronal fractures of the distal femoral condyle: a biomechanical evaluation of four internal fixation constructs

This study evaluated different fixation methods in posterior femoral condyle coronal fractures. A standardised osteotomy was created in synthetic composite femurs and fixed with one of four methods (one 3.5 mm diameter screw, two 3.5 mm screws, one 6.5 mm screw, two 6.5 mm screws). The stiffness and mean loads to specified displacements were measured. The stiffness of two 6.5 mm screws was significantly greater than both single 3.5 mm screw (3567 versus 2584N/mm; p=0.0075) and double 3.5 mm screws (3567 versus 2080N/mm; p=0.003). There was no statistical difference in the stiffness of one 6.5 mm screw compared to either the single or double 3.5mm screws. Increasing the screw diameter and using two screws increased the load at 1, 2 and 3 mm of displacement. In the fixation of posterior femoral condyle fractures, two 6.5 mm screws are more rigid than either single or double 3.5 mm screws. The use of a second screw marginally increases the rigidity of fixation. If 3.5 mm screws are used in the fixation of posterior femoral condyle fractures, at least two screws should be used to approximate the biomechanical stability of a single 6.5 mm screw.
