Efficient hip joint distraction using the AO large femoral distractor in treating acetabular fractures associated with marginal impaction and intraarticular incarcerated fragments.

PURPOSE: The results after acetabular fracture are primarily related to the quality of articular reduction. Using the AO large femoral distractor, incarcerated fragments can be easily removed, and marginally impacted fragments can be elevated under direct visualization without further re-dislocating the joint. The current study aimed to evaluate our early results of using the AO large femoral distractor as an assisting tool during ORIF of acetabular fractures associated with marginal impaction or intraarticular incarcerated fragments. METHODS: Eighteen patients were included in this retrospective case series study diagnosed with an acetabular fracture associated with either marginal impaction injury or an intraarticular incarcerated fragment. On a usual operative table, all patients were operated upon in a prone position through the Kocher Langenbeck approach. The AO large femoral distractor was used to facilitate hip joint distraction. Postoperative fracture reduction and joint clearance were assessed in the immediate postoperative CT scans. RESULTS: The average age of the patients was 30 ± 8.2 years; 13 (72.2%) were males. All cases had a posterior wall fracture, and it was associated with transverse fractures, posterior column fractures, and T-type fractures in five (27.8%), two (11.1%), and one (5.6%) patients, respectively. Intraarticular incarcerated fragments were present in 13 (72.2%) cases and marginal impaction in five (27.8%). Fracture reduction measured on the postoperative CT scans showed an anatomical reduction in 14 (77.8%) patients, imperfect in four (22.2%), and complete clearance of the hip joint of any incarcerated fragments. CONCLUSION: The use of the AO large femoral distractor is a reliable and reproducible technique that can be applied to assist in the removal of incarcerated intraarticular fragments and to ease the reduction of marginally impacted injuries associated with acetabular fractures.

Medial Humeral Epicondyle Fracture Incarcerated Into the Elbow Joint in an Adolescent Patient With Ulnar Nerve Palsy.

Medial humeral epicondyle fractures are seen in about one-fourth of all elbow fractures in the pediatric population. Though it seems to be a common occurrence, there is still controversy existing on the treatment aspects to date. Among these fractures, about one-fourth are seen incarcerated into the elbow joint and this is managed surgically. This is a case report of an adolescent male who had a medial epicondyle fracture of the humerus with the fracture fragment incarcerated into the elbow joint, and the patient also had ulnar nerve palsy, He was surgically treated with screw fixation and had an uneventful intra-operative and post-operative period.
