Neurosurgery in tanzania: A discussion of culture, socioeconomics, and humanitarians

Objective: To elucidate the progress of neurosurgical practices in Tanzania, taking into account humanitarian, socioeconomic, and geographic influences. Method: Articles, records, and historical texts were consulted to establish a timeline and history of neurosurgery in Tanzania. Results: Reulen, a German neurosurgeon, was integral to the development of sustainable neurosurgical services in Tanzania. By training Tanzanians who returned to their country to practice, Reulen helped to establish a continuity of care and legacy on which future Tanzanian surgeons could build. Subsequently, as neurosurgical services were integrated into the Muhimbili Orthopedic Institute, surgeons found a hospital to call home and a place to focus their efforts. Neurosurgical services have now been offered to the Tanzanian people for \u3e40 years, a direct consequence of international influences coupled with certain extraordinary Tanzanian physicians. Conclusions: Neurosurgery in Tanzania and Africa more generally has a long history; however, it was not until more recent efforts of certain local pioneers and educational advisors abroad that modernization occurred. The progress of the past 50 years is substantial and with continued efforts advances will continue to be made. © 2012 Elsevier Inc

Fracture of an uncemented tantalum patellar component

AbstractA 62-year-old man presented with the acute, atraumatic onset of pain 3 years after uncemented right total knee arthroplasty. He complained of new mechanical locking with the knee held in extension on examination and unable to flex the knee. On the plain radiographs, the patellar component peg was fractured and the plate was dislocated. The knee was immobilized, and revision to a cemented 3-peg component was performed. Fracture of a single-peg, tantalum-backed uncemented patellar component has not been described. Clinical suspicion for this should be given in the setting of acute locking. We recommend revision with a cemented polyethylene component
