In this study, we assessed the effect of suprainguinal facia iliaca block in maximizing the feasibility of positioning for spinal anaesthesia in patients with hip and proximal femur fractures by determining the angle that could be achieved and success rate of spinal anesthesia The control group received a sham block with the same technique of suprainguinal fascia iliaca block before being given spinal anaesthesia.

The interventional group received suprainguinal fascia iliaca block before being given spinal anaesthesia.

Inclusion Criteria:

• Patients are ASA I (American Society of Anesthesiologists physical status grade I) = normal healthy patients, ASA II (American Society of Anesthesiologists physical status grade II) = patients with mild systemic disease and no functional limitations, or ASA III (American Society of Anesthesiologists physical status grade III) = patients with moderate systemic disease and some functional limitations.
• Patients having hip and/or proximal femur fractures.

Exclusion Criteria:

• Patient refusal to participate in the study
• Patients' refusal for regional anaesthesia
• Patients have other combined fractures rather than unilateral hip or proximal femur fractures.
• Underlying coagulopathies.
• Local infection.
• Known allergy to LA.
• Body mass index (BMI) more than 40 kg/m².
• Heart block greater than first-degree.
• Renal and hepatic dysfunction.
• Neurological diseases such as Alzheimer's and dementia or apparent psychological instability.

The patient and the caregiver were blinded to the injectate in the procedure. The investigator was blinded to the solution that was used for the block, as a third person had prepared the injectate.

The one who assessed the sitting angle was blinded to the group of the patient.
