Background: The purpose of the present study was to report the perioperative complications that occurred among our initial 50 consecutive cases of HINTEGRA total ankle replacement.
Materials And Methods: This was a retrospective study of 50 cases composed of 30 men and 18 women of average age 57 years. Perioperative complications were used to compare the first 25 cases (Group A) with the subsequent 25 (Group B).
Results: Perioperative complications occurred in 15 cases (60%) in Group A but in only five (20%) in Group B. No major wound complications requiring a soft-tissue coverage procedure were encountered. Minor wound complications occurred in three cases in each group which resolved with skin grafting or topical dressing changes. One deep infection occurred in Group A, which required implant removal and antibiotic impregnated spacer prior to revision TAR. Four patients sustained intraoperative malleolus fractures in Group A, but only one in Group B. Coronal malposition of the tibial component occurred in three cases in Group A and in two in Group B. Increased sagittal slope of the tibial component occurred in two cases in Group B and sagittal malposition of the talar component occurred in two cases in Group A. There were seven instances of anterior translation of the talar component with respect to the tibial component; four in Group A and three in Group B.
Conclusion: These results suggest that TAR has a steep learning curve. Moreover, knowledge of the perioperative complications of TAR may reduce the incidence of complications.

Robotic extended total extraperitoneal transversus abdominus release for traumatic flank and abdominal intercostal hernias.
Hernia
January 2025
Department of Surgery, Corewell Health East William Beaumont University Hospital, 3601 W 13 Mile Road, Royal Oak, MI, 48073, USA.
Purpose: Traumatic abdominal intercostal/flank hernias present a perplexing challenge for surgeons seeking to repair them. There has been a paucity of studies describing robotic repairs of such hernias. We aim to evaluate the effectiveness of the Robotic-assisted Extended Total Extraperitoneal/Transversus Abdominus Release (rETEP/TAR) method in repairing traumatic abdominal intercostal and flank hernias.

Curr Pain Headache Rep
January 2025
Department of Physical Medicine & Rehabilitation, New York University Langone Health, New York, NY, USA.
Purpose Of Review: Chronic pain is highly prevalent and involves a complex interaction of sensory, emotional, and cognitive processes, significantly influenced by ambient temperature. Despite advances in pain management, many patients continue to experience inadequate pain relief. This review aims to consolidate and critically evaluate the current evidence on the impact of ambient temperature on chronic pain conditions such as fibromyalgia (FM), multiple sclerosis (MS), complex regional pain syndrome (CRPS), and osteoarthritis (OA).

Hernia
January 2025
Center for Perioperative Optimization, Department of Surgery, Herlev Hospital, University of Copenhagen, Herlev, Denmark.
Purpose: The AFTERHERNIA Project aims to shift the focus of hernia surgery towards patient-reported outcomes by examining the impact of surgical methods and long-term complications on a national level. Groin and ventral hernia repairs are common surgical procedures with significant impact on patient quality of life and healthcare costs. Most large-scale studies focus on clinical outcomes like reoperation and readmission rates, rather than patient-reported outcomes.

Department of Minimally Invasive Surgery, National University Hospital, Bukit Timah, Singapore.
Background: Given the increasing prevalence of antiplatelet agent use and the lack of high-quality evidence, the CAPTAIN trial aimed to investigate the safety and provide recommendations on continuing acetylsalicylic acid perioperatively in patients undergoing elective laparoscopic totally extraperitoneal inguinal hernia repair (LIHR).
Methods: The CAPTAIN trial was a multicentre, surgeon blind, randomized controlled trial conducted from April 2016 to April 2023. Patients undergoing LIHR were eligible for inclusion.
A Death From Necrotizing Wound Infection After Cesarean Section: Resurgence of Group A Streptococcal Puerperal Sepsis.
Am J Forensic Med Pathol
January 2025
From the Department of Pathology, University of Nevada Reno School of Medicine.
Necrotizing wound infections are potentially lethal complications of surgeries, including cesarean deliveries. A 32-year-old female with obesity and hidradenitis suppurativa (HS) underwent uncomplicated cesarean section. Four days later, she developed abdominal pain and imaging showed ascites; she was treated with antibiotics.
