Results of Autogenous Trephine Biopsy Needle Bone Grafting in Fractures of Radius and Ulna
Cortico-Cancellous bone graft harvested from the anterior iliac crest by the conventional open method is
associated with more morbidity and is more time consuming as compared to the percutaneous method using
trephine biopsy needle. The aim of the study was to determine whether cancellous bone graft harvested from
anterior iliac crest using trephine biopsy needle consistently achieved bone union in comminuted fractures
and fractures of more than 3 weeks duration of radius and ulna and also to determine the morbidity at the
donor site.
Autogenous cancellous bone graft was harvested percutaneously from 28 iliac crests in 16 patients and
applied at fracture sites of 30 forearm bones using a 4mm trephine biopsy needle after the fratures had been
fixed with plate and screws. The patients were followed up regularly upto 6 to 9 months post - operatively in
the OPD to determine the union status of the fractured bones and the morbidity at the donor site.
29 of the 30 fractures of the forearm bones united without any problems. The shaft of a trephine got bent
during the harvesting procedure at the beginning of the study due to improper technique.
Cancellous bone graft harvested from the anterior iliac crest results in predictable good union results in
comminuted fractures of forearm bones and also fractures presenting after 3 weeks of injury. It is also an
easier and quicker way of harvesting bone graft and is associated with lesser morbidity and earlier recovery
as compared to conventional open method.

Does Tranexamic Acid Reduce Perioperative Bleeding in Short Segment Pedicle Screw Fixation in Thoracolumbar Spine Fractures?
Introduction: Blood loss with spinal surgery is common potential cause of morbidity and often requires blood transfusion. Tranexamic acid (TXA), is effective in reducing bleeding in patients undergoing knee arthroplasty. TXA used in spine surgery studies have included different cases leading to inconsistence of surgical procedures. Purpose of this prospective observational study was to examine effect of TXA decreasing bleeding in short segment pedicle screw fixation for thoracolumbar fractures.
Methods: 38 patients' undergoing short segment pedicle screw for thoracolumbar fractures were enrolled in study from July to August 2013. There were 28 male and 10 female patients, with an average age of 36.5 years. Patients received 10 mg/kg of TXA or a control 30 minutes intravenously before skin incision and 3 hours post-operative and oral medication for three days. Intraoperative bleeding was estimated by weighing surgical sponges, blood collected by suction container and by subtracting all irrigation fluid. Postoperative bleeding was measured from volume in vacuum drainage bag.
Results: Twenty (20) patients were in control group and eighteen(18) to TXA group. There were no statistical differences between groups in terms of age, gender, co-morbidities, and operating time, preoperative Hemoglobin, PT and INR. Intra-operative bleeding in TXA group was significant than in control group. Post-operative drainage and Hemoglobin in first 48 h was reduced compared with placebo in TXA group. Need for post-operative transfusion was nil in TXA group.
Conclusions: Administration of TXA before surgery significantly reduces perioperative bleeding in patients undergoing short segment pedicle screw fixation for thoracolumbar spine fractures.
