In recent years there have been several case reports on laparoscopy-assisted acetabulum surgery in the literature.

According to our initial experiences with cadavers, this minimally invasive method appears promising in terms of superior visibility and easier access to the otherwise narrow and difficult fracture site in the pelvic region compared to open surgery. Furthermore, this minimally invasive method seems feasible for exact plate placement under combined endoscopic and fluoroscopic visual control.

Hip arthroplasty is rarely used as a treatment option in this population but has seen rising use over the previous decade. This study seeks to compare hip arthroplasty outcomes among young adult patients in the United States admitted with FNF by evaluating hip hemiarthroplasty (HHA) and total hip arthroplasty (THA). <b>Materials and Methods:</b> Using the National Inpatient Sample (NIS) data, adult patients less than 50 years old who underwent HHA or THA from 2016 to 2020 were analyzed. Both groups' postoperative length of stay (pLOS), total hospital charges, and prosthesis-related complications (PRCs), including mechanical loosening (ML), prosthesis dislocation (PD), and periprosthetic fracture (PPF), were analyzed and compared. <b>Results:</b> Out of 174,776,205 hospitalizations between 2016 and 2020, 15,590 young adult patients had FNF, and 2970 patients (2.18%) underwent hip arthroplasty (1195 HHAs and 1775 THAs).

Amputation and limb reconstruction are the two options that clinicians must choose. This study aims to comprehensively synthesize existing tools and resources from the literature that can assist clinicians in the decision-making process. <b>Evaluation:</b> The initial resuscitation and the prehospital care are the first important steps in the management of these injuries, while the immediate transfer to trauma centers is recommended for complex cases. After the stabilization of the patient, a thorough clinical examination of the limb is necessary with emphasis on the degree of soft tissue damage. Blunt trauma in the lower limb is associated with a higher risk of early amputation. Polytrauma patients with complex limb injuries require a holistic approach, with Damage Control Orthopedics (DCO) principles. Traumatic bleeding significantly increases mortality rates, necessitating prompt control using pressure bandages or tourniquets. Computed tomography angiography (CTA) is necessary in order to assess the viability of the limb. <b>Management:</b> Scoring systems can be used as a tool in the management of complex lower and upper limb injuries. Mangled Extremity Severity Score (MESS) calculates ischemia, shock, bone and soft tissue damage, and patient characteristics. The Narakawa Index (NISSSA score) constitutes an alteration of MESS with the implementation of a nerve injury element. The Musculoskeletal Score for Severity of Injury (MESI score) estimates the risk of limb amputation by evaluating injury, neurovascular damage, type of fracture, patient characteristics, and the period from the occurrence of trauma to the definitive treatment. Further interventions and patient preferences should be incorporated into the decision-making process. <b>Outcome:</b> The outcomes of limb salvage versus amputation for complex limb injuries encompass various factors, including patient's preinjury health status, psychological well-being, functional outcomes, and economic impact. While some studies suggest better psychological outcomes with limb reconstruction and others find similar functional outcomes between the two approaches, economic considerations play a significant role in decision-making. <b>Conclusion:</b> Managing complex limb injuries effectively necessitates a comprehensive approach involving thorough assessment, multidisciplinary collaboration, and patient-centered care.
