Advancements in hip arthroscopy are astounding. Circumferential labral reconstruction, augmentation, and capsular reconstruction valuable tools. Beyond the “comfort zone” of intra-articular realm, new frontiers include peritrochanteric space, a similarity to subacromial space shoulder makes transition attainable. In contrast, subgluteal is seen as outside box. Sciatic nerve entrapment (SNE), is...

OBJECTIVE Sensory nerve grafts are often used to reconstruct injured motor nerves, but the consequences of such motor/sensory mismatches are not well studied. Sensory nerves have more diverse fiber distributions than motor nerves and may possess phenotypically distinct Schwann cells. Putative differences in Schwann cell characteristics and pathway architecture may negatively affect the regenera...

The shoulder joint is the foundation for excellent upper extremity function. It contributes to stability and basic movements like rotation and elevation of the arm. Shoulder fusion should not be accepted even for total palsy, and nerve repair should be recommended as long as an available donor nerve exists. In planning the reconstructive procedure for shoulder function, accurate biomechanical a...

The complex reconstruction of nerves and soft tissue in the head and neck region is still challenging, especially in cases requiring external auditory canal reconstruction with facial nerve reconstruction. We report a case of left facial schwannoma extending into the external auditory canal beyond the tympanic membrane with facial paralysis in which the reconstruction of both the facial nerve a...

We present a rare case of traumatic lesion the tibial fibers sciatic nerve with spared peroneal fibers. A 33-year-old victim three month earlier stabbing attack came to our attention gait impairment and weakened left foot plantar flexion internal rotation supination. Based upon clinical signs neurophysiological investigations we suspected that injury had occurred. Ultrasound examination detecte...

BACKGROUND Microsurgical reconstruction techniques have allowed treatment of advanced head and neck carcinomas; however, it remains difficult to achieve long-term, functional reconstruction of the faciocervical muscles. To address this issue, in this we developed a rat trigeminal nerve denervation model that closely simulates the effects of oral surgery. METHODS The rat trigeminal nerve dener...

The facial nerve is the most frequently damaged nerve in head and neck trauma. Patients undergoing facial nerve reconstruction often complain about disturbing abnormal synkinetic movements of the facial muscles (mass movements, synkinesis) which are thought to result from misguided collateral branching of regenerating motor axons and reinnervation of inappropriate muscles. Here, we examined whe...
