Anterior tibial tuberosity fracture avulsion is an uncommon injury. A concomitant patellar rupture is even more scarcely encountered. We report the case of a 14-year-old male patient who suffered bilateral anterior tuberosity fractures with concomitant bilateral complete patellar tendon rupture. Adolescence, athletic activity, and high BMI may have contributed to this concomitant bilateral injury. Both lesions were treated in a one-stage repair surgery, performing an open reduction and internal fixation of the tibial tuberosity with a cannulated cortical screw and a primary tendon suture following the Krakow technique. To the authors' knowledge, no other cases of bilateral presentation of both lesions have been reported so far in the literature.

The incidence of traumatic spine fractures (TSF) is increasing worldwide, with a reported annual incidence of up to 32.8 per 100000 persons. However, there are only a few cases of spine fractures reported in adolescent idiopathic scoliosis (AIS) patients after posterior spinal fusion (PSF) in the literature. Fractures adjacent to fusion blocks that extend into the lower lumbar spine pose a unique challenge as stabilization of such fractures might require an extension of instrumentation to L5 or the pelvis. We report a novel surgical technique where bilateral pedicle and cortical screws at L4 and supplementary rods that connect the cortical screws to the main rods via dominos were implemented for optimizing the distal anchorage for TSF stabilization following an L3 Chance fracture in an AIS patient who had undergone T4-L2 posterior spinal fusion.

This study aimed to investigate the long-term serum metal ion levels of patients who received metal-on-metal hip resurfacing arthroplasty (MoM HRA). We conducted a retrospective study of 99 patients (110 hips) from March 2006 to May 2017 who underwent MoM HRA. The Harris Hip Score (HHS) and the University of California at Los Angeles (UCLA) activity score were measured, and the patients underwent clinical and radiological management. Serum levels of cobalt (Co), chromium (Cr), and molybdenum (Mo) were measured using inductively coupled plasma mass spectrometry (ICPMS) at 1, 6, and 12 months, and each year follow-up after prosthesis implantation. Patients were followed up from 1 to 156 months, with a mean of 98 months. No complications occurred. Metal ion analysis revealed significantly elevated levels compared to preoperative levels. The metal ions levels increased and reached a peak after surgery, and then the levels began to decline gradually. Approximately 84-108 months after surgery, the metal ion levels increased again to approximately peak levels. Then, up to 156 months after surgery, the metal ions levels will drop approximately to preoperative levels. The serum levels of Cr in women were higher than those in men, with the difference being statistically significant. Patients with a body mass index (BMI) of ≥24.9 kg/m2 Co levels were significantly higher than those of normal-weight patients. The serum levels of metal ions showed no significant differences between the prostheses. The use of the MoM HRA was clinically effective, and the Co, Cr, and Mo levels increased significantly after HRA; however, upon long-term follow-up, serum metal ion levels tended to decrease to preoperative levels. Longer follow-up periods and larger study samples are needed to establish the long-term outcome of patients undergoing HRA with MoM bearings. Level IV, Therapeutic Study.

Pediatric bone sarcomas, particularly osteosarcomas, present unique challenges in the realm of orthopedic oncology, given their predilection for the metaphyseal regions of long bones and the intricate balance required between achieving oncologic control and preserving limb function. This abstract encapsulates findings from a comprehensive review aimed at advancing pediatric bone sarcoma care, focusing on navigating the complications and innovating solutions for complications of limb salvage and reconstruction focusing on limb length inequalities and accompanying bone defects. Advancements in imaging, surgical techniques, and adjuvant therapies have shifted the paradigm from amputation to limb-sparing surgeries, albeit with significant challenges, especially in young patients where growth potential complicates reconstructive outcomes. The series highlights the complexity of managing limb length discrepancies (LLD), the cornerstone of limb salvage challenges, and the innovative approaches to address them, including modular endoprosthetic reconstruction with expandable prostheses, magnetic lengthening nails and biological reconstruction strategies like vascularized fibula grafts. This review underlines the importance of a multidisciplinary approach in managing pediatric bone sarcomas, where the aim extends beyond mere survival to ensuring quality of life through functional limb preservation. It highlights the need for ongoing innovation in surgical and reconstructive techniques tailored to the pediatric population's unique needs, emphasizing the potential of emerging technologies and methodologies to improve outcomes. Future research should aim to fill the existing knowledge gaps, particularly in comparing pediatric and adult surgical outcomes, to refine treatment protocols and improve patient care in this challenging domain.

Checkrein deformity of the hallux is commonly characterized by rigid flexion of the interphalangeal joint in ankle dorsiflexion but with flexibility in ankle plantarflexion which can be named as flexion checkrein deformity and as rare condition, extension checkrein deformity, characterized by rigid extension of the first metatarsophalangeal joint in ankle plantarflexion and flexibility in ankle dorsiflexion, has been reported. However, there has not reported coexistence of flexion and extension checkrein deformity. The patient, a 27-year-old male, was referred to our department 3 years after tibial and fibular fractures which was treated by open reduction and internal fixation at a previous hospital. His chief complaint was pain and impaired plantarflexion of the affected great toe. The diagnosis was double checkrein deformity characterized by simultaneous rigidity in both flexion and extension of the hallux due to the adhesion of the flexor hallucis longus (FHL) muscle and the extensor hallucis longus (EHL) tendon after a fracture. Surgical intervention was performed, which involved the transection of the FHL tendon using hindfoot endoscopy and transfer of the EHL to the extensor digitorum longus, resulting in a successful outcome with no postoperative complications. The patient demonstrated a favorable prognosis 2 years after the procedure. This report represents the first documented case of double checkrein deformity and underscores the importance of considering this condition and the potential advantages of surgical intervention.

This study aimed to summarize our experience with modified drilling epiphysiodesis and prediction methods for accurate timing of surgery and to compare the results with those of recent work by other authors. The Macnicol and Gupta modified drilling technique was used. Distal femoral and/or proximal tibial permanent epiphysiodesis was performed in 42 children (21 boys, 21 girls; median age at surgery=12.6 years, age range=9.4-15.4 years) between 2004 and 2016. Based on the groundwork of previous studies, we developed an auxological prediction method. The limb length discrepancy (LLD) was assessed by clinical examination and verified by an x-ray of the hips when standing with blocks under the shorter leg. The predicted shortening was 2.7 cm ± 1.1 cm. The final discrepancy after finishing skeletal growth was 0.5 ± 0.5 cm. In 26 patients (61.9%), equalization of both legs was achieved (0-0.5 cm). In 4 patients (9.5%), the remaining shortening was more than 1.0 cm. Shortening of an initially longer leg occurred in two patients (0.5 cm and 0.6 cm). Failure of growth plate arrest was observed in 1 patient. In another 3 patients, the efficacy of tibial epiphysiodesis was unsatisfactory. Minor complications occurred in 5 cases, but there was no evidence of angular deformity in the frontal and sagittal planes or proximal fibula overgrowth. Three patients (7.1%) returned to the operating room. Compared to published data, more patients achieved complete equalization of leg length. The results of this study verified the accuracy of the auxological prediction algorithm of LLD based on Shapiro's findings. The surgical outcome is comparable between Shapiro patterns 1 and 3. Auxological examination, assessment of bone age, and sexual maturation are crucial tools for accurate timing of surgery.

The Quality of Life Profile for spinal deformities (QLPSD) was developed to evaluate the quality of life of patients with scoliosis and other spinal deformities. The purpose of the study was to systematically translate the QLPSD into Turkish and examine the reliability and validity of the Turkish version. This methodological study was conducted with 125 participants with idiopathic scoliosis. After the translation of the QLPSD into Turkish systematically, all participants answered the Turkish version of the QLPSD (T-QLPSD) and Scoliosis Research Society-22 items (SRS-22) questionnaires. Intraclass correlation coefficient (ICC) and Cronbach's α statistics were used to test the reliability of the tools: convergent and construct validity of the tools was assessed using exploratory factor analysis and Pearson's correlation analysis. One hundred twenty-five participants were included in the study. The mean age of them was 13.7 ± 2.2 years. For the T-QLPSD total score, Cronbach's α was 0.91, and the ICC was 0.94. A very good correlation was found between T-QLPSD and SRS-22 total scores (r = -0.71). Participants with mild scoliosis reported less back pain (P = .038), better back flexibility (P=.001), and body image (P=.044) compared to moderate scoliosis. The T-QLPSD was found to be a reliable and valid scale for assessing quality of life in idiopathic scoliotic patients in Türkiye.

We investigated oxidative status in patients with rotator cuff tendinopathy (RCT) and evaluated their relationship with radiological and clinical parameters. In this cross-section study, 88 patients with RCT (59 males and 29 females) and 86 healthy controls (66 males, 20 females) were enrolled. The sample consisted of nontraumatic patients who are suffering from shoulder pain because of rotator cuff disease, which was established by clinical tests and MRI scanning. Oxidative stress in patients with RCT was analyzed via the dynamic thiol/disulfide homeostasis (TDH). Thiol/disulfide homeostasis was measured by a new colorimetric method. Furthermore, oxidative stress was indirectly measured by serum total oxidant status (TOS), oxidative stress index (OSI), and total antioxidant capacity (TAC). Serum disulfide levels and the other oxidative stress parameters of the RCT group were significantly greater than those of the control group (P < .001 for all), whereas the anti-oxidative stress parameters remained unchanged (P > .05 for all). The lowest and highest serum disulfide levels were detected in patients with grades 1 and 3, respectively (P < .001). Furthermore, in a multiple regression analysis, the disulfide/natural thiol ratio (β=-4.886, P = .004) and the MRI grading (β=0.314, P=.001) were independently associated with the Western Ontario Rotator Cuff Index WORC score. We found an association between the levels of various serum markers of oxidative injury, especially serum disulfide levels, and the increasing severity of RCT. Thiol/disulfide homeostasis seems to play a critical role in RCT, both in the beginning and during the progression of disease.

Three computed tomography (CT)-based classifications, including Haraguchi, Bartoníček-Rammelt, and Mason-Molloy systems, have been developed to better determine the characteristics of posterior malleolus fractures (PMFs). The aims of this study were (1) to determine the intra- and inter-observer reliability of the computed tomography-based classification systems and (2) to investigate the clinical experience and expertise on their reliabilities. Sixty-seven preoperative ankle CT scans of 67 adult patients with "ankle fracture with the involvement of the posterior malleolus"'' were retrospectively identified. CT images were assessed by 10 observers with different levels of clinical experience from 2 different specialties, including orthopedics and radiology. The observers were asked to classify PMFs according to 3 CT-based classifications on 2 separate occasions with a 4-week interval. Cohen's κ values were measured for 2 raters and Fleiss' κ values were measured for 3 raters and more. Overall, each classification had moderate to very good intraobserver reliability (κ=0.41 to 0.95, P < .01) as well as moderate interobserver reliability for each of the 2 separate assessments (κ=0.41 to 0.60, P < .01 for the first occasion; κ=0.44 to 0.59, P < .01 for the second occasion). Interobserver agreement among the foot and ankle surgeons regarding the Haraguchi and Bartoníček classifications was substantial for both assessment periods, whereas there was a moderate agreement for the Mason classification. Orthopedic residents showed moderate interobserver agreement in each period for both Bartoníček and Mason classifications. Radiology experts illustrated slight and fair agreements in the 2 assessments for Mason classification, moderate agreement in both assessments for Haraguchi classification, and substantial to moderate agreement in the first and second assessments for Bartoníček classification, respectively. Computed tomography-based classification system for PMFs demonstrated moderate interobserver reliability as well as moderate to very good intraobserver reliability. Moreover, foot and ankle specialists exhibit enhanced K values for both inter and intraobserver reliability for each classification system, consistency seems to increase as the interest in the field condenses.
