Tibial slope and high tibial osteotomy using the circular external fixator

Alteration of tibial slope is one of the important anatomical changes of the proximal tibia after high tibial osteotomy. Increased or decreased tibial slope can effect further total knee prosthesis procedure. In this retrospective study, 18 knees of 17 patients ( 17 female, mean age 51 range 43 - 61, mean BMI is 33.6 +/- 4.6 kg/m(2)) who were applied high tibial osteotomy using circular external fixator due to medial compartment arthrosis of the knee were evaluated in terms of tibial slope changes. While mean correction about 12.3 degrees in mechanical femoro-tibial angle was obtained in frontal plan ( P = 0.0001), significant change in tibial slope was not determined in sagittal plan ( P = 0.127). The mean posterior proximal femoral angle values were measured as 79.5 +/- 2.1 degrees preoperatively and as 80.3 +/- 2.7 degrees postoperatively and found to fall into the normal range (80.4 +/- 1.6 degrees). As there is no significant alteration in tibial slope after high tibial osteotomy performed with the Ilizarov system, complications due to alteration in tibial slope will not be experienced in follow-up or in further total knee prosthesis procedure

Acetabuloplasty at the anatomic centre for treating Crowe class III and IV developmental hip dysplasia: a case series

Introduction: Total hip replacement in patients with developmental dysplasia of the hip (DDH) is a difficult technical procedure for surgeons to perform because of the potential for these patients to have severe anomalies in their bones and soft tissues

Rotator cuff-quality of life scale: adaptation to Turkish

In general, the Turkish version of the RC-QoLS is a valid and reliable test with high differentiating power that may be used in the evaluation the quality of life of patients with RC tear in patients who are native Turkish speaker. The use of the Turkish version of RC-QoLS may contribute to the making of a more reliable evaluation in the studies on RC problems in the Turkish society

Arthroscopic removal of a subperiosteal osteoid osteoma of the talus

We report a case of a subperiosteal osteoid osteoma on the talar neck that was removed arthroscopically. Intralesional excision, en bloc resection, and percutaneous ablation techniques have all been used for the treatment of osteoid osteoma. For intra-articular osteoid osteomas, arthroscopy-assisted removal of the tumor has been described in a few case reports. Obtaining a nidus fragment for pathologic evaluation is important during arthroscopic removal of intra-articular osteoid osteomas. Sometimes it is not possible to obtain a specimen for pathologic examination. In the present case, the osteoid osteoma on the talar neck was easily located, the nidus was completely removed, and the tumor was extirpated

Osteoid Osteoma of the Trapezium: Case Report

Osteoid osteoma is a benign bone tumor representing approximately 10% of all benign bone tumors. Although osteoid osteoma of the long bones and carpus is frequent, the location in the trapezium is extremely rare. We found only one other report in the literature regarding osteoid osteoma of the trapezium. (J Hand Surg 2010;35A:636-638.

Effects of diclofenac and tenoxicam on distraction osteogenesis

Introduction In the management of bone defects, pseudoarthrosis, deformities, chronic osteomyelitis and in extremity lengthening procedures, the technique of distraction osteogenesis (DO) has been frequently used. In this experimental animal study, the effects of two non-steroidal anti-inflammatory drugs, i.e., diclofenac and tenoxicam, on the outcomes of distraction osteogenesis are investigated

Effects of calcitonin and alendronate on distraction osteogenesis

In this experimental animal study the effects of calcitonin and alendronate on distraction osteogenesis are investigated. Forty-five mature female New Zealand type rabbits were used. Rabbits were randomized into three groups, each consisting of 15 animals. Under optimal operating conditions a pre-reconstructed circular external fixator was applied to the right tibia of rabbits, and osteotomy was performed with a Gigli saw just below the tibial tuberosity. During the ten days of distraction, a placebo was administered for group I (control group), group II received 10 U of calcitonin, and group III was treated with alendronate (0.5 mg/kg/day) gavages. Rabbits were examined histologically (at the third and eighth weeks, according to Huddlestone et al.), radiologically (at the third, sixth, and eighth weeks, according to Lane and Sandhu), and mechanically (at the eighth week, as torsional loading). During the first three weeks, the groups did not differ much with regard to radiological parameters. However, in the calcitonin and alendronate groups improved histological scores were detected compared with the control group. Radiological images obtained at the end of six weeks demonstrated improved consolidation in the calcitonin and alendronate groups compared with the control group. At the end of eight weeks postoperatively, radiological and histological parameters did not differ among the groups, while torsional failure load was found to be much improved in the calcitonin group (p=0.006). During the distraction osteogenesis period, calcitonin and alendronate affected the quality of regenerate favourably. This effect is sustained until the end of the consolidation period. However, this finding needs to be supported by experimental and human studies

The butterfly suture technique for meniscal repair

One of the important factors effecting meniscal healing is the strength of primary fixation obtained by repairing technique. From this perspective, it is important to choose the technique ensuring a higher primary fixation strength for meniscal repairs. We described a new technique for meniscal repair called butterfly technique using Viper device and hypothesized that high primary fixation strength can be obtained with this technique. The study was performed on calve knees. Full-thickness longitudinal tears 2 cm in length and 3 mm medial from the periphery were created in corpora of medial menisci of 14 calves. After creating tears, menisci were divided into two equal groups. In Group 1, two vertical loop sutures 1 cm apart were placed using a Viper device. Whereas in Group 2, tears were repaired using butterfly sutures. The mean load to failure was 156.3 ± 13.1 and 186 ± 15.8 N in Group 1 and 2, respectively (p = 0.002). The fixation strength in Group 2 was significantly higher than in Group 1. We suggest that, using Viper device and all-inside butterfly suturing techniques, meniscal ruptures with appropriate locations can be repaired with higher primary fixation strength. © Springer-Verlag 2010

Biomechanical evaluation of arthroscopic all-inside meniscus repairs

Viper is a new device for arthroscopically all-inside meniscal repairing. In previous studies about Viper device, procedures were not applied arthroscopically despite this device has been designed for arthroscopic application. In this study, we evaluated primary fixation strength of arthroscopically applied meniscal repair using Viper device to obtain better clinical relevance. Two centimeter in length meniscal tear 2-3 mm far from periferic edge of medial meniscus of 50 calves were created arthroscopically. The menisci were divided into five groups including 10 menisci in each. In group 1, tears were repaired by outside-in vertical loop suture technique with No: 0 PDS. Tears were fixed by all-inside vertical suture by using Viper device with No: 0 PDS in group 2. In meniscal implant groups, RapidLoc, H-Fix, and Clearfix were applied in groups 3,4, and 5, respectively. Primary fixation strength of repairing techniques were evaluated with bio-mechanical testing machine. Fixation strengths determined in groups 1 and 2 were detected as 145 ± 13 and 136 ± 33 N, respectively. There was no difference in pull-out strength between groups 1 and 2. Fixation strengths in these two groups were significantly higher compared to groups 3, 4, and 5. There was no significant difference between group 3 (33 ± 6 N) and 5 (28 ± 6 N) in terms of fixation strengths whereas fixation strengths of these two groups were significantly higher compared to group 4 (20 ± 3 N) (P = 0.005, P = 0.018, respectively). All-inside vertical suture technique using Viper device revealed comparable primary fixation strength with outside-in vertical suture technique for meniscal repair. We suggest that the Viper device is safe and reliable for meniscal repair. © Springer-Verlag 2009

Effect of low-dose acitretin treatment on pituitary hormones in psoriasis vulgaris: A retrospective study

Background: It has been reported that retinoids may lead to hormonal alterations. Aim: In this retrospective study, we aimed to study the effect of acitretin on pituitary hormones in psoriasis patients. Methods: Out of 50 patients intended to be studied, blood samples of 43 patients could be tested before and after 3 months of acitretin therapy (0.2 to 0.5 mg/kg/day). Results: Patients mean ± standard deviation ages and female/male ratio were 46 ± 17 years and 19/24, respectively. After treatment with acitretin, gamma-glutamyltransferase, alkaline phosphatase, total cholesterol and triglyceride levels increased significantly (P < 0.05). After treatment, total protein, free thyroxine (T4) levels decreased significantly (P < 0.05). No significant differences were observed between before–after acitretin treatment regarding pituitary hormone levels in psoriasis patients (P > 0.05). Limitations: The retrospective nature of the study, inability to retest blood samples of 7 patients at 3 months post treatment, low dose and short duration of acitretin treatment were limitations of this study. Conclusion: This study showed that pituitary hormones were not affected except free T4 (thyroid hormone) by acitretin treatment. Further experimental and clinical studies are needed to clarify the effect of acitretin on pituitary hormones
