The aim of this study was to determine dimensions of the normal menisci in 174 healthy subjects by using MRI. The menisci were divided into three zones (anterior horn, mid-body, posterior horn). The height and width of the both menisci were measured. For the medial meniscus; the height and width of the anterior horn were 5.32 mm and 7.78 mm, the height and width of the mid-body were 5.03 mm and 7.37 mm, and the height and width of the posterior horn were 5.53 mm and 11.71 mm, respectively. For the lateral meniscus, the height and width of the anterior horn were 4.33 mm and 8.88 mm, the height and width of the mid-body were 4.94 mm and 8.37 mm, and the height and width of the posterior horn were 5.36 mm and 9.70 mm, respectively. Three cases (1.7%) of discoid lateral meniscus were encountered. The results of this study should help to establish standard measurements, and to differentiate between normal and pathologic conditions of the menisci of the knee joint.

Purpose Nowadays, endoscopic techniques are widely used in surgical procedures. Retroperitoneoscopy has been an extremely valuable tool for a wide variety of urologic disorders, whereas, it has limited use in orthopedic procedures. MethodsWe performed retroperitoneoscopic drainage (in combination with medical treatment) of complicated psoas abscess on 12 patients with tuberculous spondylitis. All the procedures were done under general anesthesia and in the lateral decubitus position. Psoas abscess was evacuated during procedure, and postoperatively, drainage was continued through a large silastic tube. The definitive diagnosis and the treatment were made based on the results of culture-antibiogram and PCR testing. Results Complete clinical and radiologic remission was observed in all patients in 3-6 months. The complication was not observed in any case postoperatively.Conclusions Retroperitoneoscopic drainage of psoas abscesses gains advantages in terms of rapid recovery, minimal invasiveness, absence of radiation, and shorter hospital stay. This procedure can be used not only for cold abscesses but also for other pathologies of lumbar vertebral area.

Percutaneous release of the trigger finger and trigger thumb has recently gained popularity. The aim of this study was to determine the clinical results and safety of percutaneous release in trigger thumbs. Twenty-five thumbs of 21 patients were released percutaneously in the polyclinic under local anaesthesia. Steroid injection was performed following the release procedure using the same needle. The thumb function was evaluated by a patient questionnaire, and functional thumb scores (VAS) were calculated in the preoperative and postoperative periods. At the 1 week follow-up, four patients had signs of discomfort and triggering because of incomplete release. These patients underwent open A1 pulley release. Three superficial tendon lacerations were seen during these open procedures. There were no wound complications or signs of digital nerve or artery injury in any of the patients. The preoperative mean VAS was 26.62 (18-36). This decreased to 2.57 (0-5) at the first postoperative month (P<0.001) and to 2.19 (0-3; P<0.001) at the sixth month. When the VAS scores at the first and sixth months were compared, the difference was statistically significant. We concluded that percutaneous release of trigger thumbs is a cheap, safe and effective procedure with a low rate of complications.

Hyaluronan and cortisone have controversial and an important role in the healing of degenerative osteoarthritis. The purpose of the research was to compare individual and combined effects of hyaluronan and cortisone on the healing of degenerative osteoarthritis and to determine the serum malondialdehyde level as a lipid peroxidation marker. A rabbit model was used in which a degenerative osteoarthritis was created in the articular cartilage by resection of anterior cruciate ligament. The rabbits divided into three groups namely were injected with hyaluronan (group A) and cortisone (group B) at days 31, 38 and 45. Cortisone at day 31 and hyaluronan at days 38 and 45 were injected to the third group (group C). We obtained blood samples from each rabbit to determine the malondialdehyde levels at days 1, 30, and 52. At day 52, 21 rabbits were sacrificed. In biopsies obtained from treated and untreated knees articular cartilage degeneration was examined by light microscopy. Histopathologically the healing rate was significantly higher in group C than the other groups. Degeneration decreased 72% in group A, 52% in group B and 88% in group C at day 22. Malondialdehyde levels were 2.056 +/- 0.37 in the control group, 1.94 +/- 0.54 in group A, 1.98 +/- 0.37 in group B and 1.55 +/- 0.41 in goup C. The malondialdehyde levels of group A and B were less than the control group (statistically insignificant, p > 0.05). But, there were statistically significant values between control group and group C (p < 0.05). The results showed that the combination of cortisone and hyaluronan is the most effective in the treatment of cartilage degeneration in the course of the ostearthritis and the malondialdehyde levels are correlated with the severity of degeneration.
