OBJECTIVE Retrograde ejaculation (RE) is a known complication of anterior lumbar interbody fusion (ALIF) and results from injury to the superior hypogastric plexus (SHP) during intervertebral disc exposure. Yet, there has been no recommendation for SHP mobilization. Thus, the aim of this study was to describe the anatomy of the SHP and vessels at t...
Article
The sural nerve is commonly used as an autologous nerve graft. Its harvest results in a sensory deficit in the corresponding distribution area. End-to-side neurorrhaphy of the distal sural nerve stump to the superficial fibular nerve could address the problem of sensory loss in the dorsolateral foot without altering the donor nerve. The purpose of...

The sartorius muscle is typically innervated by two branches of the femoral nerve arising from the lumbar plexus. We present an unreported variant where the sartorius muscle was innervated by an accessory branch arising from the ilioinguinal nerve in addition to the proper two branches from the femoral nerve. The iliohypogastric nerve was fused wit...

Detection of ligamentum lunotriquetrum interosseum damage, unless it is a part of complex wrist injury, is difficult during routine examination, therefore chronic instabilities are often diagnosed arthroscopically. There is no surgical procedure of choice for the treatment of chronic conditions. The authors present fifteen-year results involving 17...

As the spleen is a morphologically highly variable organ, radiologists and surgeons frequently encounter normal variants which might be misinterpreted. Accessory spleen is quite a common anatomical variation and generally does not causes any symptoms. However, the finding of an accessory spleen located outside its usual position—the splenic hilum o...
