Avulsion fracture of the posterior cruciate ligament at the tibial insertion in a child: a case report

The posterior cruciate ligament (PCL) avulsion fracture from its tibial insertion is a very rare condition in children. An isolated avulsion fracture of PCL in a child and its repair by open reduction and internal fixation with a screw is reported.     

Avulsion fractures of both anterior and posterior cruciate ligament tibial insertions

Ipsilateral femur fracture, patellar fracture, and tibial avulsion fractures of anterior and posterior cruciate ligament injuries are reported. We know of no other report of an injury such as this in the literature. We sutured the tibial avulsion fractures by transtibial suturing technique and internally fixated the femur by intramedullary interlocking nailing 2 weeks after the trauma. After 1 year the results were evaluated as very good. Early surgical repair is valuable in these injuries.     

Screw fixation of a 4 1/2-year-old PCL avulsion injury

We report about the case of a 4½-year delayed screw fixation of a tibial posterior cruciate ligament (PCL) avulsion fracture in combination with a posterolateral stabilization. After open reduction and rigid screw fixation, combined with a posterolateral stabilization using a semitendinosus tendon autograft, the patient returned to full activity in sports and daily life. If the PCL substance is sufficient, a delayed refixation in an old PCL avulsion injury seems to be a viable alternative to PCL reconstruction.     

Pseudo-arthrosis repair of a posterior cruciate ligament avulsion fracture

A pseudo-arthrosis repair of a 4-year-old bony avulsion fracture of the PCL using a minimally invasive technique, screw fixation, and bone grafting is reported. The case presented seems to be rather unique due to the fragment size and the approach for pseudo-arthrosis repair. There was a good functional result following minimally invasive pseudo-arthrosis repair of a posterior cruciate ligament avulsion fracture. There are no previous reports of similar pseudo-arthrosis repairs, and other authors report good results of delayed refixation of PCL avulsion fractures. Therefore, refixation and pseudo-arthrosis repair should be considered as a viable treatment.     

Spectrum of MR imaging findings in spinal tuberculosis

OBJECTIVE: We describe three patients who presented with radiographic findings of a fragment on the medial side of the tibial plateau of the knee that represented an avulsion of the deep portion of the medial collateral ligament. These findings were all associated with disruption of the posterior cruciate ligament and a peripheral medial meniscal tear-the so-called reverse Segond fracture. CONCLUSION: Avulsion fracture at the tibial insertion of the deep component of the medial collateral ligament is a rare finding. When this type of injury is diagnosed, the radiologist should consider posterior cruciate ligament injury and peripheral medial meniscal tears as possible associated findings.     

Biomechanical comparison of three techniques for fixation of tibial avulsion fractures of the anterior cruciate ligament

Purpose

To evaluate the initial stability of a suture anchor fixation and to compare this with a screw fixation and pull-out suture fixation for anterior cruciate ligament tibial avulsion fracture.

Methods

The initial fixation strength of 3 different fixation techniques, antegrade cannulated screw fixation, pull-out suture fixation with Ethibond and bioabsorbable knotless suture anchor fixation, was evaluated. Using 14 fresh cadavers (28 knees), the strength to failure, initial displacement and mode of failure were measured.

Results

The strength to failure of the suture anchor fixation was not significantly different from that of the screw fixation and was higher than that of the pull-out suture fixation. The initial displacement of the suture anchor fixation was lower than that of the screw fixation and the pull-out suture fixation. The majority of the suture anchor fixations and the screw fixations were failed by pull-out from the bone. Eight of the 56 suture anchor fixations failed by pull-out of the suture from the ligament proper. And, one of the 7 screw fixations failed due to fracture of the avulsed bony fragment. All of the pull-out suture fixations failed by suture material rupture.

Conclusions

These biomechanical results suggest that the initial fixation strength of suture anchor fixation was not less than that of screw fixation or pull-out suture fixation. And, the initial displacement of suture anchor fixation was lower than that of screw fixation or pull-out suture fixation. The suture anchor fixation appears to be a good alternative fixation technique for repair of anterior cruciate ligament tibial avulsion fracture.     

Semimembranosus tendon avulsion fracture of the posteromedial tibial plateau associated with posterior cruciate ligament tear and capsular rupture

Semimembranosus tendon avulsion fractures are an uncommon occurrence and are often associated with anterior cruciate ligament (ACL) and medial meniscus tears. We present the imaging features of an unusual case of semimembranosus avulsion fracture of the posteromedial tibial plateau associated with posterior cruciate ligament (PCL) tear, medial meniscus tear, and capsular rupture in a 26-year-old man with a football injury.
