The case report we present concerns a 65-year-old male patient with idiopathic osteonecrosis of the left femoral head. After repeated cycles without the significant success of physiotherapy treatments, due to the worsening of the painful symptoms in the left coxo-femoral site with increasing functional limitation, it was decided to proceed with decompression surgery of the femoral head using a cannulated biological screw which due to its intrinsic structural characteristics, allowed the simultaneous application in the neck and femoral head of PRP growth factors prepared at the time of surgery. The clinical picture surprisingly regressed in a very short time with a complete functional recovery in the absence of significant pain. The MRI examination performed before the treatment in place, compared with a similar examination after 5 months, shows sub-total remission of the signal affecting the trabecular structure of the cephalic portion of the femur in line with the clinical picture just reported.

Idiopathic Osteonecrosis of The Femoral Head: A CASE REPORT

History and Physical Examination 

Man aged 65, complains about two years right coxalgia worsening and debilitating with progressive difficulty in walking.



Lower limbs normally conformed and positioned without dysmetria, hip ROM dx reduced for severe pain, 100° flexion, extension 0°, 30° abduction, adduction 10°, internal rotation 15°, external rotation 30°, atrophy gluteal muscles (Trendelemburg+) and quadriceps disuse, no neurological deficits. After Rx pelvis/hip and MRI showed a right OSTEONECROSIS of the femoral head in stage II sec. Ficat and Arlet. 



Osteonecrosis of the femoral head

  • MULTIFACTORIAL origin affects persons of 40 – 60 YEARS
  • 50% OF CASES ARE BILATERAL  and in 10% may also, involve OTHER JOINTS
  • PAIN, alteration of the ANATOMY AND BIOMECHANICS of the hip and a GROWING DISABILITIES constitute the natural historyof this disease


It is a progressive, degenerative disease in which we observe the necrosis of osteocytes, osteoblasts and osteoclasts that populate an area of the variously defined femoral head. Diagnosis is often difficult; for this reason, MRI is the best diagnostic method for osteonecrosis.

The primary objective in the treatment of osteonecrosis of the femoral head is to implement an early intervention, to avoid or procrastinate implantation of total hip arthroplasty. The patient is treated, in one surgical session in spinal anesthesia, with a method that associates the mechanical core-decompression of the outbreak osteonecrosis, through the guidewire, and biological action obtained through the introduction of PRP through a cannulated screw titanium equipped of holes.

  • Significant and immediate pain relief
  • Disappearance of claudication
  • Postural recovery
  • Immediate resumption of normal daily activities
  • Suspension of all analgesics
