BACKGROUND The objective of this study was to evaluate the causes of failed endoscopic carpal tunnel release (CTR) in order to detect potentially hazardous operative steps. The intraoperative findings of 10 microsurgically revised cases were retrospectively analyzed. RESULTS From January 1999 to October 2001, ten patients underwent open revision surgery after being referred because of failed ...

In patients with advanced stages of cancer, severe pain is commonly encountered and is very difficult to treat. It affects the quality of life of the patient and the families involved. Pain can be managed using analgesics and adjuvant therapy. However, studies have shown that at least 10%-15% of patients fail to control pain adequately and will experience severe pain. We discuss the case of a 6...

Chronic Pain is a serious public health problem both in the United States and globally. Neurolysis therapy with radiofrequency, phenol/alcohol, and cryotherapy has been used in pain management for several decades. Characteristics of each modality are reviewed in this article including: history, mechanism, clinical indication, contraindication, side effects, and efficacy. An extensive literature...

Let e be an edge of a median graph G which is contained in exactly one 4-cycle. Then it is proved that G n e is a median graph. The converse holds as well provided that e is not contained is a subgraph isomorphic to the 3-cube minus a vertex. These results are used to give several characterizations of median grid graphs. (Grid graphs are subgraphs of complete grids, i.e. of the Cartesian produc...

We report a recurrent Piriformisc muscle syndrome after surgical release. After the primary neurolysis, a second operation was performed to release adhesions. This case shows a different type of sciatic nerve entrapment by an abnormal thin muscle slip. Results of the revision surgery guide us to the point that revision surgery for Piriformis muscle syndrome should be meticulously selected, and ...
