ReviewUltrasound-guided interventional procedures in pain medicine: a review of anatomy, sonoanatomy, and procedures. Part IV: hip.
Ultrasound-guided injection in pain medicine is emerging as a popular technique for pain intervention. It can be applied for the intervention procedures in the hip region. The objectives of this review article were to review the relevant anatomy and sonoanatomy of the hip joint and the trochanteric bursae, to describe the techniques for ultrasound-guided injections, and to examine the efficacy and accuracy of such injections.

Randomized Controlled Trial Comparative StudyThe effects of ultrasound-guided adductor canal block versus femoral nerve block on quadriceps strength and fall risk: a blinded, randomized trial of volunteers.
Adductor canal block (ACB) has been suggested as an analgesic alternative to femoral nerve block (FNB) for procedures on the knee, but its effect on quadriceps motor function is unclear. We performed a randomized, blinded study to compare quadriceps strength following adductor canal versus FNB in volunteers. Our hypothesis was that quadriceps strength would be preserved following ACB, but not FNB. Secondary outcomes included relative preservation of hip adduction and degree of balance impairment. ⋯ Compared with FNB, ACB results in significant quadriceps motor sparing and significantly preserved balance.

Comparative StudySleep apnea and total joint arthroplasty under various types of anesthesia: a population-based study of perioperative outcomes.
The presence of sleep apnea (SA) among surgical patients has been associated with significantly increased risk of perioperative complications. Although regional anesthesia has been suggested as a means to reduce complication rates among SA patients undergoing surgery, no data are available to support this association. We studied the association of the type of anesthesia and perioperative outcomes in patients with SA undergoing joint arthroplasty. ⋯ Barring contraindications, neuraxial anesthesia may convey benefits in the perioperative outcome of SA patients undergoing joint arthroplasty. Further research is needed to enhance an understanding of the mechanisms by which neuraxial anesthesia may exert comparatively beneficial effects.
