Pediatric Knee Injury: A Unique Case of Intra-articular Osteochondral Fracture Following Penetrating Trauma.

Penetrating injuries to the musculoskeletal system pose common challenges for orthopedic surgeons in emergency departments (EDs). The complexity escalates when a joint is affected, increasing the risk of severe complications such as infection and post-traumatic arthritis. Given the potential importance of these injuries, early diagnosis and a meticulous treatment plan are crucial. In this paper, we present a unique case of penetrating trauma, resulting in an intra-articular defect on the lateral femoral condyle of an adolescent girl. This case underscores the importance of tailored interventions in managing complex musculoskeletal injuries.

Double Fixation Technique for Acute Acromioclavicular Joint Dislocation Using the Two-Button Technique and Gracilis Autograft Reinforcement: A Case Report of an Elite Athlete Seeking a Rapid Return to Sports Activity.

Acromioclavicular joint dislocation is a relatively common injury in the general population, especially in younger ages. Although acromioclavicular injuries are a well-studied topic, there are many controversies concerning not only the best way to treat them by operative or conservative methods but also determining the most effective fixation methods, providing better functional outcomes, faster rehabilitation protocols, fewer complications, and lower recurrence rates. In this case report, we present a case of type III acromioclavicular dislocation in a young athlete who was treated operatively using a double fixation technique, aiming to address these controversies and offer insights into the optimal management of such injuries.

Upper extremity vascular injuries: Etiology, management and outcome.

BACKGROUND: Vascular injuries of the upper extremities are considered relatively rare injuries affecting mostly the young population. They often are complex injuries accompanied by other musculoskeletal trauma or trauma in other anatomic locations. Their management is challenging since they can lead to disabilities with major socioeconomic effects. AIM: To analyze data about the mechanism of injury, the management algorithm and functional outcomes of vascular injuries of the upper extremity. METHODS: One hundred and fifteen patients (96 males and 19 females) with arterial injuries of the upper extremity treated in a tertiary trauma center from January 2003 to December 2022 was conducted. Mean patients' age was 33.7 years and the mean follow up time was 7.4 years. Patients with Mangled Extremity Severity Score ≥ 7 and Injury Severity Score ≥ 20, previous upper limb surgery or major trauma and any neuromuscular or psychiatric disease were excluded, from the study. RESULTS: A penetrating trauma was the most common cause of injury. The radial artery was the artery injured in most of the cases (37.4%) followed by the ulnar (29.5%), the brachial (12.1%) and the axillary (6%). A simultaneous injury of both of the forearm's arteries was in 15.6% of the cases. In 93% of the cases there were other concomitant musculoskeletal injuries of the extremity. Tendon lacerations were the most common, followed by nerve injuries. The postoperative functional scores (full Disabilities of the Arm, Shoulder, and Hand and VAS) had very satisfactory values. CONCLUSION: Although vascular injuries of the upper extremity are rare, they may occur in the context of major combined musculoskeletal trauma. Although a multidisciplinary approach is essential to optimize outcome, the ability of trained hand surgeons to repair all injuries in combined vascular and musculoskeletal upper extremity trauma, excluding isolated vascular injuries, ensures shorter operative times and better functional outcomes.
