Safe surgical dislocation for hip joint preservation surgery
Published in K. Mohan Iyer, Hip Preservation Techniques, 2019
The anastomotic branch of the inferior gluteal artery runs along the inferior border of the piriformis muscle and provides additional supply to the femoral head. Hence, the insertion of the piriformis and all the short external rotators are kept intact and dissection is maintained between the superior part of the piriformis and gluteus minimus. This serves as double insurance for protecting femoral head blood supply.

The superior and inferior gluteal arteries are branches of the internal iliac artery. As they leave the pelvis, they are separated by the piriformis muscle (Figure 7.3.6). The superior gluteal artery divides into deep, superior and inferior branches which supply the glutei and give arterial muscular perforators to the overlying skin. The inferior gluteal artery in a similar fashion supplies the glutei and the lower buttock skin becoming the infragluteal artery at the lower border of the gluteus maximus. This artery anastomises with branches of the medial femoral circumflex artery to form a subfascial plexus along the posterior thigh. This plexus is the basis of the posterior thigh fasciocutaneous flap which is described below.

Biceps femoris has two parts to it, a short and long head. This is the only muscle of the thigh that inserts laterally on the leg. The short head is mostly hidden by the long head. The two heads form a common belly and eventually have a common attachment distally. The long head originates at the ischial tuberosity and inserts on the lateral side of the head of the fibula. It is a type II muscle and measures 7 X 10 cm2. Actions of this muscle are flexion of the leg and extension of the thigh. The short head originates at the linea aspera and lateral supracondylar line of the femur and inserts at the same spot as the long head; they share the same tendon. This muscle is not expendable, because it is a strong flexor of the leg. The major artery of the long head is the first perforating branch of the profunda femoral artery, which is found at the medial aspect of the muscle. Other arteries of the muscle are the second branch of the profunda, which supplies the lower portion of the muscle medially and the inferior gluteal artery at the muscle’s origin. The second or third perforating branches of the profunda enter the short head close from the femur close to its origin and supply blood to it. Also, the superior lateral genicular artery off of the popliteal artery perfuses the muscle distally.

The CO2 insufflation to 25 mm Hg remained consistent throughout the dissection in 16 of the 17 hips, allowing for visualization of the sciatic nerve, posterior femoral cutaneous nerve, pudendal nerve, branch of the inferior gluteal artery crossing the sciatic nerve, piriformis muscle, hamstring tendon origin, and lesser trochanter. Following the visualization, the anatomic structures were marked with sutures (Figure 2). The CO2 insufflation was not successful in one hip with a BMI of 33 kg/m2. In addition to the 30° and 70° arthroscopes, 5 and 10 mm endoscopes of 0° were also tested for visualization of the DGS. The straight visualization from the 0° endoscopes provided a broader view than the angled arthroscopes. In opposition, the arthroscopes were more effective in demonstrating an anatomic structure in a different perspective without changing the portal. Following the endoscopic procedures, the suture-marked structures in the DGS were confirmed through a Kocher-Langenbeck approach (Figure 3).

Initially we were interested in knowing the location of the vessels (superior and inferior gluteal artery) and the point at which they made contact with the gluteus maximus.7 At that time, we injected colorant using one of the most common approaches in our practice (injection into the middle of the superior intergluteal crease). We were worried about going too deep and possibly puncturing the vessels. We used angles of 30 and 45 degrees. We found that by going deep (45 degrees), we had a greater chance of approaching the vessels. It is important to mention that no vessel ruptures were identified.
