The frequent finding of bilateral DVT and unsuspected contralateral DVT in patients with unilateral symptoms, and the even more frequent finding of DVT in patients with bilateral symptoms, clearly indicates that both categories of patients need to be evaluated with bilateral US.

In the 75% of patients with moderate or high mobility, there were no DVT cases. The 6.4% DVT incidence was limited to patients with low mobility and was significantly lower than the norm for this procedure. A larger, randomized study is needed to confirm the benefits of the mobility allowed by an active-fixation lead.

Gout is a common metabolic disorder, typically diagnosed in peripheral joints. Tophaceous deposits in lumbar spine are a very rare condition with very few cases reported in literature. The following is a case report of a 52-year-old patient with low back pain, left leg pain, and numbness. Serum uric acid level was in normal range. magnetic resonance imaging, bone scan, and gallium-67 images suggested an inflammatory-infectious process focus at L4. After a decompressive laminectomy at L4–L5 level, histological examination showed a chalky material with extensive deposition of amorphous gouty material surrounded by macrophages and foreign-body giant cells (tophaceous deposits).

We show a patient who presented leg pain triggered by intense exercise. The most likely diagnosis was a possible tibial stress fracture or a "shin splint" syndrome (soleus enthesopathy). We performed a bone scintigraphy including SPECT/CT that revealed the presence of the two concomitant pathologies. SPECT/CT identified the hot spot superimposed with bone lesion in the tibial stress fracture and only remodeling activity without evidence of cortical lesions in the enthesopathy processes.
