It seems that bleeding from the holes of proximal cannulated screws is a simple and accurate perfusion assessment technique for predicting the development of AVNFH after a femoral neck fracture. Given that assumption, primary arthroplasty might be an appropriate choice as a treatment method in a nonbleeding-group patient whose treatment choice is ambivalent or who might not be able to undergo additional surgery should he or she develop a subsequent AVNFH after internal fixation of femoral neck fracture.

Transforaminal selective epidural block (TFSEB) technique is used for spinal pain management. Multiple recent reports cite TFSEB resulting in complications such as life-threatening infections, spinal fluid leaks, positional headaches, adhesive arachnoiditis, hydrocephalus, air embolism, urinary retention, allergic reactions, intravascular injections, stroke, blindness, neurological deficits/ paralysis, hematomas, seizure and death. We present herein a case of TFSEB induced retroperitoneal hematoma resolution with conservative treatment.
