PURPOSE: We wanted to analyze the causes of fixation failure after performing compression hip screw fixation for intertrochanteric fracture and we wanted to evaluate the methods to mange this type of failure. MATERIALS AND METHODS: From January 1999 to August 2005, 15 patients who underwent operation due to fixation failure after compression hip screw fixation for intertrochanteric fracture were evaluated, with at least 1 year follow up, for the fracture type, the status of the reduction, the aspects of failure, the causes of the failure and the clinical and radiologic results after operation. RESULTS: There were 7 cases of cut out by the hip screw, 1 case of hip screw breakage, 1 case of dislodging the hip screw, 2 cases of excessive sliding of the hip screw, 2 cases of plate breakage and 2 cases of fixation loss of the plate. The failure of cases was due to incorrect choice of the implants, and that of 9 cases was due to technical error. The Harris Hip score was an average of 67.8 for 10 cases of failed arthroplasty at the last follow up and 88.4 for 4 cases of re-fixation with a 95 degree angled blade plate, and bone union was achieved at a minimum of 5 months. CONCLUSION: It is important to choose an adequate implant and a precise technique to achieve a successful result for fixation of unstable intertrochanteric fracture, and refixation with a 95 degree angled blade plate could be considered for the management of failed intertrochanteric fracture with arthroplasty.

Neurolymphomatosis, which is defined as a peripheral nerve infiltration of lymphoma, is an infrequent complication of systemic lymphoma and the isolated involvement of the peripheral nerve as a sign of recurrence is very rare. Here, we report a case with neurolymphomatosis presented as a mononeuropathy multiplex and is the first reported case in Korea. With potent chemotherapy, the blood-nerve barrier may have a critical role in the isolated recurrence of lymphoma in the peripheral nervous system.

Gastroduodenal intussusception is an rare condition usually caused by prolapse of a gastric tumor with subsequent invagination of a portion of the stomach wall into the duodenum. Symptoms are protean, but classically patients have presented with episodic epigastric abdominal distress, a history of intermittent vomiting and gastroduodenal bleeding, either as melena, hematochezia, or stools positive for occult blood. Examination generally discloses a fullness or mass in the epigastrium. Its typical radiologic presentation includes luminal narrowing, distally converging gastric folds, infolding and outpouching of the gastric wall, a filling defect, and a coil-spring pattern. A 71-year-old man was admitted for epigastric pain and melena which required blood transfusions. Endoscopy showed an unexplained pulling-down of part of the gastric body and the pylorus couldn't be identified. An upper GI barium examination demonstrated a huge lobulated mass from the distal antrum of stomach to the duodenal cap. On abdominal sonography, double contour of stomach wall was seen at the proximal portion of narrowing stomach. At surgery, a large, intraluminally exophyting gastric mass prolapsed into duodenum was excised and diagnosed as leiomyoma of stomach.

OBJECTIVE: The purpose of this study was to evaluate the physicochemical properties and cytocompatibility of microporous, spherical biphasic calcium phosphate(BCP) ceramics with a 60/40 hydroxyapatite/beta-tricalcium phosphate weight ratio for application as a bone graft substitute. MATERIALS AND METHODS: Microporous, spherical BCP granules(MGSB) were prepared and their basic characteristics were compared with commercially available BCP(MBCP; Biomatlante, France) and deproteinized bovine bone mineral(Bio-Oss; Geistlich-Pharma, Switzerland, BBP; Oscotec, Korea). Their physicochemical properties were evaluated by scanning electron microscopy, X-ray diffractometry, Fourier-transform infrared spectroscopy, inductively coupled plasma atomic emission spectrometer, and Brunauer-Emmett-Teller method. Cell viability and proliferation of MC3T3-E1 cells on different graft materials were evaluated. RESULTS: MGSB granules showed a chemical composition and crystallinity similar with those in MBCP, they showed surface structure characteristic of three dimensionally, well-interconnected micropores. The results of MTT assay showed increases in cell viablity with increasing incubation times. At 4d of incubation, MGSB, MBCP and BBP showed similar values in optical density, but Bio-Oss exhibited significantly lower optical density compared to other bone substitutes(p < 0.05). MGSB showed significantly greater cell number compared to other bone substitutes at 3, 5, and 7d of incubation(p < 0.05), which were similar with those in polystyrene culture plates. CONCLUSION: These results indicated the suitable physicochemical properties of MGSB granules for application as an effective bone graft substitute, which provided compatible environment for osteoblast cell growth. However, further detailed studies are needed to confirm its biological effects on bone formation in vivo.
