Effects of Femoral Canal Opening Technique on Biomarkers
Effects of Femoral Canal Opening Technique on Inflammation, Coagulation, Organ Dysfunction, and Bone Metabolism
This single-centre prospective randomized study consisted of 60 participants (50 women) with a mean age of 80.33 ± 11.13 years, randomly allocated to either manual medullary canal opening (n = 30) or mechanical drilling of the canal (n = 30). Outcomes were assessed preoperatively and postoperatively during a 72-hour follow-up period. This study had a prospective design. Outcomes were assessed preoperative and during the follow-up period to 72 hours after surgery. During follow-up, all patients underwent laboratory testing. Blood samples were collected 2 hours preoperatively and 72 hours postoperatively in order to determine blood concentrations of leukocytes, erythrocytes, platelets (×10⁹/L), haemoglobin (g/L), D-dimers (IU/L), prothrombin time, international normalized ratio (INR), activated partial thromboplastin time (aPTT) (s), aPTT ratio, fibrinogen (g/L), creatinine (μmol/L), N-terminal pro-B-type natriuretic peptide (NT-proBNP) (pg/mL), C-reactive protein (CRP) (mg/L), glucose, urea, sodium, potassium, chloride, calcium, and phosphorus (mmol/L), as well as bone metabolism markers: total procollagen type 1 N-terminal propeptide (tP1NP) (µg/L), N-min osteocalcin (N-mOST) (µg/L), C-terminal telopeptide of type I collagen (β-CTX) (ng/mL), and bone-specific alkaline phosphatase (BAP) (µg/L).
The investigatoras compared differences in blood parameters between the two groups at baseline, as well as differences after 72 hours. In addition, the investigators analysed the dynamics (baseline vs. 72 hours) of outcome measures between the two study groups.

Inny: manual medullary canal opening
Tthe medullary canal was opened under fluoroscopic guidance using a cannulated curved awl (14.0/3.2 mm).
|
All participants were operated on according to the same protocol, using the same type of procedure on a traction table, with prior fracture reduction under fluoroscopic (X-ray) guidance.
All patients had the same type of fracture (pertrochanteric femoral fracture), and intramedullary osteosynthesis was performed using a ⌀ 9.0 mm, 340 mm Proximal Femoral Nail Antirotation (PFNA) (Synthes GmbH, Oberdorf, Switzerland).
In the first group, the medullary canal was opened under fluoroscopic guidance using a cannulated curved awl (14.0/3.2 mm).
In the second group, the medullary canal was opened under fluoroscopic guidance using a battery-powered surgical drill equipped with a cannulated drill bit (13.0 mm diameter, 290 mm length) (Synthes GmbH, Oberdorf, Switzerland).
