BackgroundChronic schizophrenic patients have been reported as having higher osteoporosis prevalence. Survey the bone mass among schizophrenic patients and compare with that of the local community population and reported data of the same country to figure out the distribution of bone mass among schizophrenic patients.Methods965 schizophrenic patients aged 20 years and over in Yuli Veterans Hospital and 405 members aged 20 and over of the community living in the same town as the institute received bone mass examination by a heel qualitative ultrasound (QUS) device. Bone mass distribution was stratified to analyzed and compared with community population.ResultsSchizophrenic patients have lower bone mass while they are young. But aging effect on bone mass cannot be seen. Accelerated bone mass loss during menopausal transition was not observed in the female schizophrenic patients as in the subjects of the community female population.ConclusionSchizophrenic patients have lower bone mass than community population since they are young. Further study to investigate the pathophysiological process is necessary to delay or avoid the lower bone mass in schizophrenia patients.

BackgroundThe epidemiology of acute orthopedic dislocations is poorly understood. A nationwide database provides a valuable resource for examining this issue in the Taiwanese population.MethodsA 6-year retrospective cohort study of 1,000,000 randomly-sampled beneficiaries from the year 2005 was used as the original population. Based on the hospitalized and ambulatory data, the concomitant ICD9-CM diagnosis codes and treatment codes were evaluated and classified into 8 and 3 major categories, respectively. The cases matching both inclusive criteria of dislocation-related diagnosis codes and treatment codes were defined as incident cases.ResultsDuring 2000-2005, the estimated annual incidence (per 100,000 population) of total orthopedic dislocations in Taiwan was 42.1 (95%CI: 38.1-46.1). The major cause of these orthopedic dislocations was traffic accidents (57.4%), followed by accident falls (27.5%). The annual incidence dislocation by location was shoulder, 15.3; elbow, 7.7; wrist, 3.5; finger, 4.6; hip, 5.2; knee, 1.4; ankle, 2.0; and foot, 2.4. Approximately 16% of shoulder dislocations occurred with other concomitant fractures, compared with 17%, 53%, 16%, 76% and 52%, respectively, of dislocated elbow, wrist, hip, knee, and ankle cases. Including both simple and complex dislocated cases, the mean medical cost was US

1,248 for the ankle.ConclusionsIn Taiwan, three-quarters of all orthopedic dislocations were of the upper limbs. The most common complex fracture-dislocation was of the knee, followed by the wrist and the ankle. Those usually needed a treatment combined with open reduction of fractures and resulted in a higher direct medical expenditure.

BackgroundOsteoporosis is a bone disease that can reduce both bone mass and bone strength. It can cause serious fractures of bones, along with causing significant and even devastating physical, psychological and financial consequences for patients and their family members. Many reports have revealed that the prevalence of decreased bone density is higher in schizophrenic patients than in the non-psychological diseased population. The previous report of our group revealed that chronic schizophrenia patients have poorer BUA levels since they were young as compared to the general community population. Hyperprolactinemia and antipsychotics are reported to be among the risk factors for osteoporosis in chronic schizophrenic patients.Methods93 schizophrenic patients with severely poor adjusted BUA values and 93 age and gender matched patients with normal adjusted BUA values from a previous survey study were selected. Data were collected via questionnaires and via reviews of antipsychotic medications. Blood samples were drawn, and serum levels of prolactin, estradiol, testosterone, magnesium, calcium, phosphate, osteocalcin, Cross-linked N-teleopeptide of type I collagen (NTX), thyroid hormone and parathyroid hormone were checked. The association between BUA levels and serum levels of the above items, along with the type of received antipsychotic medication, was evaluated.ResultsThere was no significant association found between reduced BUA levels and serum prolactin, calcium, phosphate, osteocalcin, NTX, thyroid stimulating hormone and parathyroid hormone levels. There was also no association between BUA levels and types of currently received antipsychotics. There was no association between BUA levels and menstruation condition in female patients. Hypermagnesemia had a borderline association with classical and combined (classical and atypical) antipsychotic medications in male patients. Nevertheless, hypermagnesemia is a significant protective factor of reduced BUA levels in female patients. Hyperprolactinemia had a significant association with classical and combined antipsychotic medications in female patients. Hyperprolactinemia, however, provides a protective effect on reduced BUA levels in male patients. There was no significant association found between serum prolactin level and the type of antipsychotic medication received.ConclusionsThe results of this study are in contrast with literature that has reported an association between bone mass and serum prolactin levels, serum magnesium levels and type of received antipsychotics. Further study to investigate the pathophysiological process and the association between bone mass and serum prolactin level, serum magnesium level and specific antipsychotics is necessary.

IntroductionThe minimally invasive plate osteosynthesis (MIPO) technique has been introduced recently. The extensive comminuted fractures of the distal radial metaphysis with diaphyseal involvement are probably good indications for MIPO technique because of less extensive dissection and soft-tissue stripping. The purpose of this retrospective study was to compare the clinical results of MIPO technique to those of conventional open reduction in extensive metadiaphyseal fractures of distal radius.Materials and methodsOf 34 patients treated for comminuted metadiaphyseal fractures of the distal radius between June 2006 and May 2012, all the patients had extra-articular fractures. Twenty-one patients underwent MIPO technique and 13 underwent conventional open reduction with long periarticular locking plates system (Zimmer). Six patients in the MIPO group and three in the conventional group who had concomitant distal ulnar fractures or distal radioulnar joint (DRUJ) injury underwent plate osteosynthesis or Kirschner-wire fixation before radial fixation. Perioperative parameters and union time were recorded. Radiologic assessment, Mayo Wrist Score, and satisfaction scale were evaluated at the final follow-up.ResultsAll fractures united without secondary procedures. Radiologic assessment, Mayo wrist score, and time to union showed no significant difference between the two groups, but the MIPO group had significantly smaller incision wound, higher satisfaction scale, and shorter operative time than did the conventional group.ConclusionsMIPO is capable of achieving functional results as good as those of conventional open reduction, with a higher satisfaction scale, smaller incision, and shorter operative time. When MIPO intervention is planned, concurrent distal ulnar fracture or DRUJ injury should be repaired first, thus facilitating subsequent indirect reduction. For treating intra-articular fractures, anatomical reduction of the articular surface is more important, and the MIPO technique described here is not recommended.
