Twenty-nine patients with avascular necrosis of the femoral head after injury have been treated by operation. Multiple drilling of the femoral head was performed, necrotic bone removed and a muscle-pedicle bone graft implanted into the head and neck of the femur. In 17 of the patients the necrosis was associated with an un-united femoral neck fracture, in 11 it occurred after the fracture had u...

Untreated osteonecrosis of the femoral head ultimately leads to collapse and disintegration of hip joint. The predegenerative stages of osteonecrosis especially when seen in young adults, should be treated by a femoral head preservation operation with the objective to delay and possibly to avert the above consequences. Previously head preserving surgeries were not in vogue so total hip replacem...

STUDY DESIGN Retrospective case series. OBJECTIVE To describe a modified technique for mini-open transforaminal lumbar interbody fusion (TLIF) that improves visualization for decompression, fusion, and freehand pedicle screw insertion. Accuracy of freehand pedicle screw placement with this technique was assessed. SUMMARY OF BACKGROUND DATA Mini-open TLIF is a minimally invasive technique th...

Finding an appropriate soft-tissue grafting material to close a wound located over the dorsum of a finger, especially the distal phalanx, can be a difficult task. The boomerang flap mobilized from the dorsum of the proximal phalanx of an adjacent digit can be useful when applied as an island pedicle skin flap. The vascular supply to the skin flap is derived from the retrograde perfusion of the ...

Surgical treatment for spinal tuberculosis includes focal tuberculosis debridement, segmental stability reconstruction, neural decompression and kyphotic deformity correction. For the lesions mainly involved anterior and middle column of the spine, anterior operation of debridement and fusion with internal fixation has been becoming the most frequently used surgical technique for the spinal tub...

BACKGROUND Percutaneous pedicle screw instrumentation is a minimally invasive surgical technique; however, the effects of using percutaneous pedicle screw fixation in treating patients with spinal infections have not yet been well demonstrated. The aim of this study, therefore, was to determine whether percutaneous posterior pedicle screw instrumentation is superior to the traditional open appr...

Delayed presentation of fracture neck femur is not uncommon in our scenario and difficult to treat because precarious vascularity bony defect at site. The purpose the present study analysis functional outcome muscle pedicle bone graft porcedure ununited children adolescents. : Sixteen patients with (presenting late) adolescents were treated quadratus femoris based along open reduction internal ...

OBJECTIVES Head and neck reconstruction is still challenging in terms of esthetic and functional outcomes. This study investigated the feasibility of the angular branch-based scapular tip free flap (STFF). METHODS This was a retrospective study of 17 patients undergoing maxillectomy and mandibulectomy and either primary or secondary reconstruction by STFF. This study included surgical, esthet...

STUDY DESIGN Cadaveric biomechanical study. OBJECTIVE To determine fatigue behavior of cortical bone trajectory (CBT) pedicle screws. SUMMARY OF BACKGROUND DATA Cortical bone trajectory screws have been becoming popular in spine surgery; however, the long-term fatigue behavior of the new CBT screws remains understudied and limitations not well defined. METHODS Twelve vertebrae from six ca...
