lateral intermuscular septum of the thigh and short head of the biceps femoris muscle an anatomic investigation with new clinical applications
Plastic and Reconstructive Surgery, 2001Co-Authors: Akiteru Hayashi, Yu MaruyamaAbstract:An anatomic study was performed to reappraise the vasculature of the lateral intermuscular septum of the thigh and muscles associated with it using 12 preserved cadaver legs. Several possible new clinical applications of the lateral intermuscular septum and the short head of the biceps femoris were identified as follows: (1) short head of biceps femoris muscle or musculoseptal flap based on the second and/or third profunda perforating vessels, or based on the superior lateral genicular vessels, with or without the Iliotibial Tract and the deep fascia, and with or without the motor nerve of the short head; (2) transverse extension of the fascial portion of the tensor fasciae latae muscle or musculocutaneous flap to include the lateral intermuscular septum; (3) combination use of items 1 and 2, above; and (4) free septofascial graft using the lateral intermuscular septum and Iliotibial Tract. It is anticipated that the distally based short head of the biceps femoris muscle flap will be an additional option for repairing defects around the knee, and that a free short head of the biceps femoris muscle flap based on the profunda femoris perforating vessels will be useful in functional reconstruction such as reanimation of the paralyzed face. The lateral intermuscular septum can be incorporated into the short head of biceps femoris muscle flap or into the tensor fasciae latae flap, and it also can be used as a free fascial graft. Functional deficit resulting from harvesting the short head of the biceps femoris and the lateral intermuscular septum is minimal, and donor wound at the lateral lower thigh seems to be acceptable.

Huiskes R: Hip-joint and abductor-muscle forces adequately represent in vivo loading of a cemented total hip reconstruction
2014Co-Authors: Jan Stolk, Nico Verdonschot, R HuiskesAbstract:Using finite element analyses, we investigated which muscle groups acting around the hip-joint most prominently affected the load distributions in cemented total hip reconstructions with a bonded and debonded femoral stem. The purpose was to determine which muscle groups should be included in pre-clinical tests, predicting bone adaptation and mechanical failure of cemented reconstructions, ensuring an adequate representation of in vivo loading of the reconstruction. Loads were applied as occurring during heel-strike, mid-stance and push-off phases of gait. The stress/strain distibutions within the reconstruction, produced by the hip-joint contact force, were compared to ones produced after sequentially including the abductors, the Iliotibial Tract and the adductors and vastii. Inclusion of the abductors had the most pronounced effect. They neutralized lateral bending of the reconstruction at heel-strike and increased medial bending at mid-stance and push-off. Bone strains and stem stresses were changed accordingly. Peak tensile cement stresses were reduced during all gait phases by amounts up to 50 % around a bonded stem and 11% around a debonded one. Additional inclusion of the Iliotibial Tract, the adductors and the vastii produced relatively small effects during all gait phases. Their most prominent effect was a slight reduction of bone strains at the level of the stem tip during heel-strike. These results suggest that a loading configuration including the hip-joint contact force and the abductor forces can adequately reproduce in vivo loading of cemented total hip reconstructions in pre-clinical tests. # 2001 Elsevier Science Ltd.

reconstruction of the anterior cruciate and anterolateral ligament deficient knee with a modified Iliotibial graft reduces instability more than with an intra articular hamstring graft
Knee Surgery Sports Traumatology Arthroscopy, 2020Co-Authors: Sb Eljaja, Vd Siersma, Aa Amis, Lars Konradsen, Kiron K Athwal, Michael Rindom KrogsgaardAbstract:To compare knee kinematics before and after anterior cruciate ligament ACL reconstruction (ACL-R) using hamstring graft (HG) and a double-stranded Iliotibial Tract graft attached to Gerdy’s tubercle (providing an extra-articular anterolateral tenodesis) (named the modified Iliotibial Tract graft = MIT). Eighteen cadaveric knees were tested in a 6 degree of freedom kinematics rig. An optical tracking system recorded kinematics of the knee from 0 to 80 degrees of flexion applying no load, internal/external rotation (IR/ER), valgus/varus rotation (VGR/VRR), simulated pivot shift (SPS), anterior translation (AT) and posterior translation loads. The knee was tested before and after resection of the ACL and the anterolateral ligament (ALL), respectively; then after HG-ACL-R and MIT-ACL-R. Grafts were fixed at 20° of flexion. Results were compared to the intact knee. ACL resection resulted in a significant increase in AT (p < 0.05) over the entire range of motion, peaking at 20° of flexion, mean difference 6.6 ± 2.25 mm (p = 0.0007). ACL-R with HG-ACL and MIT-ACL restored AT. Resection of the ALL increased IR in the fully extended knee, mean difference 2.4 ± 2.1° (p = 0.024). When compared to the intact knee and the knee after HG-ACL-R, MIT-ACL-R knee reduced IR/SPS significantly (p < 0.05) in deep flexion angles (60°–80°), peaking at 80° of flexion. The MIT-ACL-R caused significantly less VRR at 80° flexion (p = 0.02). MIT-ACL-R restored AT equally to the HG-ACL-R. The MIT-ACL-R reduced IR and SPS in deep flexion, resulting in overconstraint. MIT-ACL-R can be used as an alternative to standard reconstruction methods.
