Primary hydatid cyst of vastus lateralis muscle.
Musculoskeletal system is rarely involved by hydatid cyst,the larval form of Echinococcus Granulosus. A 37-year old man was diagnosed as having a cystic mass within his left thigh musculature. Preoperative computerized tomography suggested an unusual location of echinococcus although serology could not confirm the diagnosis. During surgery, a white coloured cyst within left vastus lateralis mus...
متن کاملVastus lateralis muscle flap for infected hips after resection arthroplasty.
We evaluated the potential of a vastus lateralis muscle flap in controlling infection after resection arthroplasty of the hip. We retrospectively reviewed 119 patients with 120 chronic infections after resection arthroplasty treated with this procedure. The flap was fixed with Mitek anchors in the acetabular cavity. The mean duration of infection after resection before the muscle flap procedure...
متن کاملLimitations of the Vastus Lateralis Muscle as a Substitute for Lost Abductor Muscle Function: An Anatomical Study.
Abductor insufficiency after hip arthroplasty resulting from an impaired gluteus medius and minimus remains an unsolved problem in orthopaedic surgery. The vastus lateralis (VL) was described as a functional substitute for abductor insufficiency in 2004. We carried out a macrodissection of twelve cadaveric hemipelvises to investigate the innervation of the VL and adjacent muscles to assess the ...
متن کاملVersatility of the free vastus lateralis muscle flap.
BACKGROUND A flap that carries sufficient tissue with satisfactory pedicle length or diameter and with minor donor site morbidity is an ideal option for the reconstructive surgeon. Many flaps have been described with each one having specific advantages. The vastus lateralis (VL)-muscle flap is among them, but no special attention has been given to its valuable use. To evaluate and to propagate ...
متن کاملMuscle fiber and tendon length changes in the human vastus lateralis during slow pedaling.
Muscle fascicle lengths of vastus lateralis (VL) muscle were measured in five healthy men during slow pedaling to investigate the interaction between muscle fibers and tendon. Subjects cycled at a pedaling rate of 40 rpm (98 W). During exercise, fascicle lengths changed from 91 +/- 7 (SE) to 127 +/- 5 mm. It was suggested that fascicles were on the descending limb of their force-length relation...
