Diagnosis and Management of Intraoperative Periprosthetic Fractures in Primary Total Knee Arthroplasty.

Intraoperative periprosthetic fracture is an uncommon but notable complication that can occur during primary total knee arthroplasty. These fractures may occur at various stages during the procedure, including surgical exposure, implant preparation, implant trialing, and final implantation. Management of femoral and tibial fractures necessitates intraoperative recognition, including attentiveness of preoperative patient and surgical risk factors. This comprehensive review article focuses on the patient and surgical risk factors, diagnosis, management, and outcomes related to intraoperative fractures during primary total knee arthroplasty.

The impact of surgical trainee involvement in total hip arthroplasty: a systematic review of surgical efficacy, patient safety, and outcomes.

PURPOSE: Concerns persist that trainee participation in surgical procedures may compromise patient care and potentiate adverse events and costs. We aimed to analyse the potential impact and consequences of surgical trainee involvement in total hip arthroplasty (THA) procedures in terms of surgical efficacy, patient safety, and functional outcomes. METHODS: We systematically reviewed Medline/PubMed, EMBASE, the Cochrane library, and Scopus databases in October 2021. Eligible studies reported a direct comparison between THA cases performed with and without trainee involvement. RESULTS: Eighteen publications met our eligibility criteria and were included in our study. The included studies reported on 142,450 THAs completed on 142,417 patients. Specifically, 48,155 and 94,295 surgeries were completed with and without trainee involvement, respectively. The mean operative times for procedures with (n = 5,662) and without (n = 14,763) trainee involvement were 106.20 and 91.41 min, respectively. Mean overall complication rates were 6.43% and 5.93% for THAs performed with (n = 4842) and without (n = 12,731) trainees. Lastly, the mean Harris Hip Scores (HHS) for THAs performed with (n = 442) and without (n = 750) trainee participation were 89.61 and 86.97, respectively. CONCLUSION: Our systematic review confirmed previous studies' reports of increased operative time for THA cases with trainee involvement. However, based on the overall similar complication rates and functional hip scores obtained, patients should be reassured concerning the relative safety of trainee involvement in THA. Future prospective studies with higher levels of evidence are still needed to reinforce the existing evidence.

Radial Polydactyly.

¼ Radial polydactyly is one of the most common congenital anomalies of the hand, with an incidence of 0.08 to 1.40 per 1,000 live births; it requires surgical treatment early in life.¼ Polydactyly occurs during weeks 5, 6, 7, and 8 of embryogenesis, principally due to misregulation of the sonic hedgehog protein within the developing limb bud.¼ The Flatt classification system of preaxial polydactyly (types I to VII), as published by Wassel, categorizes preaxial polydactyly based on osseous abnormalities, but it has substantial limitations.¼ For improved function and appearance, preaxial polydactyly ideally requires surgical intervention at an early age (between 1 and 2 years of age) before the development of fine motor skills.

Osteomalacia and Insufficiency Fractures Secondary to Intravenous Iron Therapy: A Case Report.

Introduction: Intravenous (IV) iron therapy is associated with hypophosphatemia, and long-term administration may lead to osteomalacia and insufficiency fracture. Awareness of this complication could severely reduce patient morbidity. Our patient continued her iron therapy for 17 months after her initial complaint. After switching iron medications, the patient's fractures healed completely and she is now pain free. Case Report: A 61-year-old woman presented with a fracture in her right femoral neck and a non-displaced fracture in her left femoral neck. After total hip arthroplasty and pinning, the patient returned with bilateral insufficiency fractures of the medial tibial plateau. The fractures were secondary to her iron medication, ferric carboxymaltose (FCM). Conclusion: Fibroblast growth factor 23 (FGF23) is a protein that increases renal phosphate wasting and certain parenteral iron therapies may increase the activity of FGF23. Most IV iron medications have been shown to cause hypophosphatemia, but literature has indicated that FCM is associated with the highest risk of developing hypophosphatemia and possibly osteomalacia.
