Is There a Correlation Between the Change in the Interscrew Angle of the Eight-Plate and the Delta Joint Orientation Angles?
Objectives It is known that the screws of the eight-plate hemiepiphysiodesis construct diverge as growth occurs through the physis. Our objective was to investigate whether there is a correlation between the amount of change of the joint orientation angle (JOA) and that of the interscrew angle (ISA) of the eight-plate hemiepiphysiodesis construct before and after correction. Patients and methods After the institutional review board approval, medical charts and X-rays of all patients operated for either genu valgum or genu varum with eight-plate hemiepiphysiodesis were analyzed retrospectively. All consecutive patients at various ages with miscellaneous diagnoses were included. JOA and ISA were measured before and after correction. After review of the X-rays, statistical analyses were performed which included Pearson correlation coefficient and regression analyses. Results There were 53 segments of 30 patients included in the study. Eighteen were males, and 12 were females. Mean age at surgery was 9.1 (range 3–17). Mean follow-up time was 21.5 (range, 7–46) months. The diagnoses were diverse. A strong correlation was found between the delta JOA (d-JOA) and delta ISA (d-ISA) of the eight-plate hemiepiphysiodesis construct (r = 0.759 (0.615–0.854, 95%CI), p < 0.001). This correlation was independent of the age and gender of the patient. Conclusions There is a strong correlation between the d-ISA and the d-JOA. The d-ISA follows the d-JOA at a predictable amount through formulas which regression analysis yielded. This study confirms the clinical observation of the diverging angle between the screws is in correlation with the correction of the JOA. Level of evidence Level IV, Therapeutic study.PubMedWoSScopu
Translation, cross-cultural adaptation, reliability, and validity of Turkish version of the university of California Los Angeles (UCLA) shoulder scale into Turkish
Purpose To translate and culturally adapt the University of California Los Angeles (UCLA) shoulder scale into Turkish (T-UCLA) and determine its psychometric properties. Material and methods The UCLA scale was translated into Turkish using Beaton guidelines. Ninety-one patients (46 male; mean age: 46.0 +/- 13.7 years) with shoulder disorders completed T-UCLA and American Shoulder and Elbow Score (ASES), Simple Shoulder Test (SST) and 36-Item Short Form (SF-36). Test-retest reliability was tested in 50 patients at a mean of 5.2 +/- 2.2 days after initial assessment. Validity was evaluated in 91 patients, and correlations between ASES, SST and SF-36 were analyzed. Responsiveness was assessed in 33 patients who underwent arthroscopic rotator cuff repair with a mean follow-up of 12.8 +/- 0.5 months. Results Test-retest reliability of overall T-UCLA, pain and function subscales were 0.96, 0.94 and 0.86, respectively. The correlation coefficients between T-UCLA and SST and ASES were r = 0.752 and r = 0.783, respectively (p < 0.001). The highest correlations between T-UCLA and SF-36 were observed in physical functioning (r = 0.64) and bodily pain subscales (r = 0.66). No ceiling or floor effect observed. Overall and subscales of T-UCLA were highly responsive (ES = 3.22-4.31). Conclusion T-UCLA has sufficient reliability and validity similar to original and translated versions. T-UCLA is responsive in patients who underwent rotator cuff repair
Prevalence of human papilloma virus types in Turkish and Albanian women
Background: Human papilloma virus (HPV) infection is the major etiologic agent of cervical carcinoma. The aim of this study was to determine the prevalence of HPV infection and genotype distribution in cervical swabs from 2,234 Turkish and 357 Albanian women with similar lifestyles from two different countries. Materials and Methods: HPV detection and typing were performed by type specific multiplex fluorescent PCR and fragments were directly genotyped by high resolution fluorescence capillary electrophoresis. Results: The most common type was HPV 16 and the second one was HPV 6 for both country. The third common type was 39 and 18 for Turkish and Albanian women, respectively. Conclusions: When we compare our results with other studies, there are differences between the frequency and order of the HPV genotypes detected at the second and subsequent frequencies. This may due to differences in the quality and type of samples analyzed, as well as the HPV detection methods
Two-Stage Revision Anterior Cruciate Ligament Reconstruction Using Allograft Bone Dowels
Revision anterior cruciate ligament (ACL) reconstruction is substantially more challenging than primary reconstruction. Management of previously malpositioned or widened tunnels often requires innovative approaches for managing bony defects. Massive osteolysis with poor bone stock and convergence or overlapping of revision tunnels into the previously placed tunnels may necessitate a staged revision procedure. In this surgical technique description, we describe a method for the management of bony deficiencies using allograft bone dowels in staged revision ACL reconstruction
Surgical Management of the Multiple-Ligament Knee Injury
The management of multiligament knee injury is a complex process starting with the adequate identification of the injury. A detailed physical and radiographic examination with a thorough understanding of knee anatomy is crucial to assess all damaged structures: anterior cruciate ligament, posterior cruciate ligament, posteromedial corner including the medial collateral ligament, and posterolateral corner including the lateral collateral ligament. Several surgical techniques have been developed throughout the years to adequately address these ligament insufficiencies. In this surgical technique description, we describe a reproducible method for the assessment and surgical management of a knee dislocation (KDIV) injury. Our approach includes using anatomic single-bundle cruciate ligament reconstructions with modified Bosworth technique for medial-side injuries and a combination of MĂĽller popliteal bypass and Larson figure-of-8 techniques for posterolateral corner injuries. The orders of surgical steps is described concisely, and technical controversies such as graft choice, tunnel positioning, and sequence of graft fixation are discussed in detail
Meniscal Ramp Lesion Repair by a Trans-septal Portal Technique
The identification of meniscal ramp lesions can be quite difficult or even impossible with conventional anterior arthroscopic viewing and working portals. Although even the use of transnotch viewing maneuvers into the posteromedial compartment increases the likelihood of diagnosis, it is the posteromedial and trans-septal portals that provide the best direct visualization of these many times “hidden lesions.” In this surgical technique description, we describe a method to not only adequately visualize the ramp lesion, but also provide subtle variations to existing surgical techniques that can help limit injury to neurovascular structures as well as gain satisfactory vertical suture repair of this posteromedial meniscocapsular injury
Peritoneum and omentum are natural reservoirs for chondrocytes of osteochondral autografts: A comparative animal study
The purpose of this study was to investigate the effects of the omentum, peritoneum, paratenon and skeletal muscle on the proliferation of the cartilage tissue using rabbit model as an in vivo culture medium. 6 months old forty-five New Zealand rabbits were randomized into omentum, peritoneum, muscle, and Achilles paratenon groups. Standard sized osteochondral grafts were harvested from right knees and immediately placed into the specified tissues. Control group was fresh cartilage at the end of follow-up. After five months, samples were collected and evaluated macroscopically by measuring their dimensions (vertical = D1, horizontal = D2, and depth = D3) and volumes, and histologically by counting the chondrocyte number using camera lucida method. Macroscopically, increase in mean values for D1 and D2 dimensions of specimens from paratenon and omentum compared to pretransplant dimensions was statistically significant (p 0.05). Histologically, mean chondrocyte count was 14.0 ± 0.6 in fresh articular cartilage. Mean chondrocyte counts were 14.4 ± 0.9 in omentum group, 15.4 ± 1.0 in peritoneum group, 9.7 ± 1.3 in muscle group and 9.2 ± 0.4 in Achilles paratenon group respectively. However, mean chondrocyte counts were higher in samples of omentum and peritoneum group compared to fresh articular cartilage, increase was not statistically significant (p > 0.05). Transplantation of the cartilage grafts into mesothelium enhanced the chondrocyte counts and volumes compared with the pretransplant measurements. Mesothelium may have the potential to be used as an in vivo culture medium for osteochondral tissue growth
