Fractures around Trochanteric Nails: The "Vergilius Classification System".

INTRODUCTION: The fractures that occurred around trochanteric nails (perinail fractures, PNFs) are becoming a huge challenge for the orthopaedic surgeon. Although presenting some specific critical issues (i.e., patients' outcomes and treatment strategies), these fractures are commonly described within peri-implant ones and their treatment was based on periprosthetic fracture recommendations. The knowledge gap about PNFs leads us to convene a research group with the aim to propose a specific classification system to guide the orthopaedic surgeon in the management of these fractures. MATERIALS AND METHODS: A steering committee, identified by two Italian associations of orthopaedic surgeons, conducted a comprehensive literature review on PNFs to identify the unmet needs about this topic. Subsequently, a panel of experts was involved in a consensus meeting proposing a specific classification system and formulated treatment statements for PNFs. Results and Discussion. The research group considered four PNF main characteristics for the classification proposal: (1) fracture localization, (2) fracture morphology, (3) fracture fragmentation, and (3) healing status of the previous fracture. An alphanumeric code was included to identify each characteristic, allowing to describe up to 54 categories of PNFs, using a 3- to 4-digit code. The proposal of the consensus-based classification reporting the most relevant aspects for PNF treatment might be a useful tool to guide the orthopaedic surgeon in the appropriate management of these fractures.

Porto-mesenteric venous gas as a sign of gastric mucosal damage remitted after surgery: a case report.

Porto-mesenteric venous gas (PMVG) is a severe sign of abdominal organs damage. Imaging diagnostic criteria allow the detection of PMVG and should be applied in the presence of severe symptoms and signs of abdominal organs damage. Our case had clinical signs of epigastric pain and abdominal tenderness and ultrasonography and computed tomography evidence of PMVG and gastric cancer. The subsequent surgery, without complications, induced PMVG to disappear and the patient to be dismissed from hospital.

Knee septic arthritis caused by α-hemolytic Streptococcus in a patient with a recent history of knee arthroscopy: a case report.

BACKGROUND: Arthroscopic partial meniscectomy is a common procedure in orthopedic practice. Infections are uncommon complications of this procedure with an incidence rate of 0,01% - 3,4%. Staphylococcus spp are the predominant causative agents in such cases. We present a case of knee septic arthritis caused by α-hemolytic Streptococcus. CASE PRESENTATION: A 22-year-old woman diagnosed with obesity (body mass index [BMI] 35 kg/m2) but with no other major comorbidities underwent an arthroscopic selective meniscectomy with administration of intravenous cefazolin for antibiotic prophylaxis. After an uneventful period of 2 months, the patient returned with pain, fever and a discharging sinus at the site of anterolateral arthroscopic portal. Blood tests and magnetic resonance imaging revealed osteomyelitis involving the tibial plate. Cultures of synovial fluid obtained from the knee and a pharyngeal swab yielded α-hemolytic Streptococcus. Five days later, the patient underwent arthroscopic debridement with partial synovectomy. Intraoperative specimens yielded α-hemolytic Streptococcus. The patient received intravenous piperacillin/tazobactam, followed by an associative regimen of amoxicillin and clindamycin with clinical, laboratory and instrumental evidence of symptom resolution. CONCLUSION: The incidence of knee septic arthritis after arthroscopic partial meniscectomy is 0.01-3.4%. This infection is usually caused by Staphylococcus spp. and in rare cases by commensal bacteria, such as α-hemolytic streptococci, secondary to transient bacteremia. Screening of the colonized area is important to prevent possible transient bacteremia. Diagnosis is based on isolation of the causative organisms from synovial fluid cultures, and treatment comprises arthroscopic debridement with individualized systemic antibiotic therapy based on the results of an antibiogram.

Obstructing left sided colorectal cancer. A retrospective single Center study.

BACKGROUND: In recent years, with population aging, there has been an increased number of colorectal cancer cases with severe occlusion symptoms. About 75% of obstructions due to malignant colorectal cancer (10-30%) occur distal to splenic flexure. METHODS: The authors evaluated the best surgical therapeutic strategy to be used in cases of left-sided colorectal carcinoma in patients over 65 years old, especially considering the emergency condition, age of patients and efficacy in terms of postoperative morbidity, mortality and 5 years survival rate. RESULTS: The management of left-sided obstructing colorectal carcinoma is controversial. Hartmann's procedure is the best therapeutic choice in elderly patients. However, resection with intraoperative colonic wash-out and primary anastomosis has favorable outcome in low risk patients. CONCLUSIONS: A review of the literature reveals that primary resection and anastomosis for left-sided obstructing CRC is the correct therapeutic strategy in low risk patients with localized, resectable carcinoma, without peritonitis; Hartmann's procedure should be adopted in doubtful cases and in high risk patients.
