1/3. Osteoporotic vertebral fracture adjacent to a nonsegmented hemivertebra.A combination of osteoporotic vertebral fractures and congenital spinal deformity is theoretically possible, but there have been no reports on this combination in the literature. We describe a rare case of an osteoporotic vertebral fracture adjacent to the nonsegmented hemivertebra. A 60-year-old postmenopausal woman who did not recall any specific trauma presented with severe back pain. She had markedly decreased bone mineral density and significant lumbar kyphoscoliosis with a nonsegmented hemivertebra between L1 and L2 on radiographs of the lumbar spine. magnetic resonance imaging (MRI) revealed a vertebral fracture adjacent to the nonsegmented hemivertebra. Laboratory studies showed increased serum bone-specific alkaline phosphatase (BAP) and urinary type I collagen crosslinked N-telopeptide (NTx). A thoracolumbar brace was applied for 3 months. Daily administration of alendronate normalized her serum BAP and urinary NTx levels. MRI scans of the lumbar spine after 6 months also confirmed normalized signal intensities of the fractured vertebra adjacent to the nonsegmented hemivertebra. The vertebral fracture seemed to be induced by spinal malalignment, increased stress on the adjacent level of the fused segment, and its fragility due to osteoporosis.- - - - - - - - - - ranking = 1keywords = spine, spinal (Clic here for more details about this article) |
2/3. Management of lower extremity malalignment during running with neuromuscular retraining of the proximal stabilizers.This case report presents a high-level female runner with a history of more than 25 years of recurrent lower extremity (LE) injuries and LE malalignment problems during running. Due to her LE malalignment, she has been unable to run for the past 3 years. A definitive diagnosis was not found for her inability to run so by exclusion we diagnosed dysfunction of the hip, spine, and pelvic stabilizers that resulted in her in LE malalignment. To treat this muscle weakness, we designed a Pilates-evolved functional movement intervention to improve the control and strength of the proximal stabilizers and regain normal LE alignment. The Pilates-evolved treatment approach involved a series of functional and progressive resistance exercises designed to dynamically stabilize the spine, pelvis, and hip through all planes of motion. After 1 year of Pilates-evolved training, the athlete's disabling movement pattern resolved and she has returned to a regular running program. The purpose of this case report is to describe a Pilates-evolved functional movement intervention that resolved this runner's LE malalignment and returned her to running when other traditional treatment approaches were not effective in doing so.- - - - - - - - - - ranking = 0.95347351578252keywords = spine (Clic here for more details about this article) |
3/3. High tibial osteotomy with use of the Taylor Spatial Frame external fixator for osteoarthritis of the knee.BACKGROUND: High tibial osteotomy (HTO) is used to treat medial compartment osteoarthritis of the knee in active patients with varus alignment. In this study we review the clinical and radiographic outcomes associated with the Taylor Spatial Frame (Smith & Nephew), and its use in HTOs, and we include an illustrative case report. methods: In 7 patients with medial compartment osteoarthritis of the knee and varus alignment, the Taylor Spatial Frame was applied to the tibia in the operating room and a proximal tibial osteotomy was performed. patients followed a computer-generated turning schedule until the desired correction was achieved. The frame was removed when the osteotomy site had healed. The lower extremity measure (LEM) was used to assess physical function. Clinical outcome measures relating to the Taylor Spatial Frame included latency, time to correction, time in the frame, number of residual corrections and complications. Radiographic outcomes included preoperative Resnick grades of osteoarthritis, pre- and post-correction limb alignment and tibial slope measurements. RESULTS: Average (and standard deviation) LEM grade at a mean 41 (14) months follow-up after correction was 94% (5%). Average latency was 8 days, time to correction was 15 days, time in the frame was 23 weeks and number of residual corrections was 1.3. Complications were similar to those for external fixators. Radiographic correction goals were met in all patients. CONCLUSION: The Taylor Spatial Frame is a valuable asset when using HTO to treat medial compartment osteoarthritis of the knee.- - - - - - - - - - ranking = 34250.653545262keywords = osteoarthritis (Clic here for more details about this article) |
