The results were assessed with the SPSS 9.05 program, and the repeatability coefficient of both methods was 98%. The average difference in angle determination between the two methods was 0.9 degrees; the maximum difference was 3 degrees. After that, posteroanterior semi-axial radiographs of both humerus bones of 40 healthy volunteers were taken by positioning their arms in 20 degrees abduction to the X-ray axis. The mean HRA difference between the right and left sides was 0.4 degrees (maximum difference 3 degrees ) and is of no clinical significance. It was determined that left and right HRAs can be taken as a reference to each other. For measurement of the HRA in the planning of proximal humeral rotation osteotomy and prosthesis replacement arthroplasty, the presented radiographic method can be used with a high rate of accuracy.

We evaluated the efficacy of tigecycline and teicoplanin in a rat model of MRSA osteomyelitis. Osteomyelitis was induced with an intramedullary injection of 10(8 )colony-forming units (cfu) of MRSA. After osteomyelitis formation was confirmed on Day 14, infected rats were randomly divided into three groups: tigecycline (n=13), teicoplanin (n=13), and no-treatment control (n=14). A 28-day antibiotic therapy with a subcutaneous injection of tigecycline (14 mg/kg twice daily) or intramuscular administration of teicoplanin (20 mg/kg daily) was administered. Rats were then sacrificed, and the tibias were harvested. The bones were weighed and then cultured. Our results indicated that bacterial growth was significantly reduced in teicoplanin and tigecycline groups, compared to the control group (p=0.019 and p=0.006, respectively). However, no difference was detected between the two antibiotic groups (p=1.000). No bacterial growth was detected in 7 out of 13 and 9 out of 13 specimens of the teicoplanin and tigecycline treated groups, respectively. Although this result was numerically in favor of tigecycline, the difference was not statistically significant (p=0.427). In conclusion, tigecycline, a novel antibiotic, appears as an effective alternative to teicoplanin in the treatment of osteomyelitis caused by MRSA.

Subcalcaneal heel pain is one of the most common foot ailments, yet the exact etiology is still controversial. Nerve entrapment has been suggested as one of the possible causes of this painful condition in recalcitrant cases. The purpose of this study is to determine the role of nerve entrapment in painful heels. Twenty patients with heel pain (25 heels) were compared with an age and body mass index-matched control population using electrodiagnostic methods. The results of the study revealed 22 heels (88%) with heel pain had lateral plantar nerve entrapment signs with or without medial plantar nerve findings on EMG. There were no abnormal values in the control group. Nerve entrapment syndrome has previously been considered only in cases with intractable heel pain, but this study suggests that it may play a role the early phases of painful heel syndrome.

The purpose of this study was to investigate the biomechanical efficacy of Histoacryl (cyanoacrylate, Nasetil 2 butyl sistein) in meniscal tear repair. In our study, the primary stability of three different repair techniques in delaying the formation of a gap of 2 mm was investigated. A meniscal tear was repaired with two vertical sutures and Histoacryl in the first group; it was repaired only with Histoacryl in the second group, and with only two vertical sutures in the third group. Menisci were then placed in a tensile loading machine, and the primary stability of the repair zones was measured until a displacement of 2 mm occurred. Biomechanical force was significantly (P<0.05) high (112.0±17.20 N) in all groups when vertical suture and Histoacryl glue were used together during displacements of 0.5, 1.0, 1.5 and 2.0 mm. We believe that Histoacryl is superior to vertical sutures regarding gap delaying. It potentiates the effect of vertical suture strength, permits early motion and thus merits an in vivo study.
