Percutaneous Pinning of the Hip is usually done for patients that are suffering from a Femoral Neck Fracture & blood supply to the femoral head has NOT been compromised. If there is a lack of blood supply to the femoral head a Hemiarthroplasty will most likely be performed.
Percutaneous Pinning’s are done with the patient being placed on the Fracture Table. The fracture table allows the surgeon to place traction on the leg & reduce the fracture before surgically fixing it.
A Guide Pin are drilled from externally on the patients hip diagonally through the femoral neck into the femoral head. X-rays are taken in A/P & Lateral to confirm proper placement. Next a small incision is made, this is done so that when that when the Parallel Guide or Honeycomb Guide is placed it will sit against bone. 1-2 more guide pins will be placed.
After the pins are in good position the surgeon will use the Depth Gauge to determine the length of the screw needed to be implanted into the patient.
Next, the surgeon will drill over the guide pin with the Cannulated Drill Bit (only the outer cortex of the bone needs to be drilled).
The pre-selected length Screw will then be given to the surgeon on the Power Screwdriver (this is done on power because of the length of the screw)
Last, the screws will be final Hand tightened with the Hand Screwdriver.
