    (Lippincott Williams & Wilkins, 2024) Tosyali, Hakan Koray; Kaya, Hueseyin; Hancioglu, Sertan; Tamsel, Ipek; Orguc, Sebnem; Tekustun, Ferit; Kayikci, Kayahan
    This study aimed to evaluate the differences between mini-open (MO) and arthroscopic (ART) repair procedures for rotator cuff tendon tears in terms of clinical and radiological outcomes. This retrospective study included 59 patients, and data were collected prospectively. Patients with full-thickness rotator cuff tears were randomized to undergo MO or ART repair at 2 centers by 2 surgeons between January 2012 and December 2017. Data were collected 3 weeks before surgery and 6 and 12 months after surgery. Physical function was assessed using the American Shoulder and Elbow Surgeons index, VAS, and Constant scoring system. Radiological outcomes were assessed using the Sugaya classification, adapted for ultrasound. Changes between baseline and follow-up were compared between the 2 groups. Fifty-nine patients who underwent ART or MO rotator cuff repair were included in this study. The 2 groups had similar demographic characteristics and preoperative baseline parameters. Both the MO and ART groups showed statistically significant improvement in outcome parameters (P <= .0001); however, cuff repair integrity was significantly better in the ART group (P = .023). All other improvements in the patient-derived parameters were equivalent. None of the patients in either group required revision surgery. According to the results of our retrospective study, MO and ART rotator cuff repair are effective and viable options for surgeons to repair rotator cuff tears. There were no differences in objective and subjective outcomes between the full ART and MO techniques for rotator cuff tears. Surgeons should choose a technique with which they are more familiar.

    Composite Reconstruction With Irradiated Autograft Plus Total Hip Replacement After Type II Pelvic Resections for Tumors Is Feasible but Fraught With Complications
    (Lippincott Williams & Wilkins, 2024) Vahabi, Arman; Tosyali, Hakan Koray; Kececi, Burcin; Sabah, Dundar; Kaya, Huseyin
    BackgroundMalignancies involving the pelvic ring present numerous challenges, especially in the periacetabular area. Extensive resection of the pelvic region without reconstruction can lead to severe functional impairment. Numerous reconstructive options exist, but all have drawbacks. Extracorporeally irradiated autografts are one option for reconstruction after periacetabular resections; they offer the potential advantages of eliminating the risk of allogeneic reactions associated with allografts and preserving local anatomy. However, little is known about the durability and risks of this approach in pelvic reconstruction.Questions/purposes(1) What are the survival rates of the autograft used, and if there is graft loss, what is the extent of this loss? (2) What are the functional outcomes after the implementation of this method? (3) What is the rate and nature of complications associated with this approach?MethodsThis is a retrospective case series from one subspecialty tumor unit that evaluated patients treated between January 2005 to January 2022. During that time, three surgeons treated 48 patients with Type II resections (defined as resection of periacetabular area). Patients treated with isolated Type II resections were eligible, as were those treated either with Type I+II resections, Type II+III resections, Type I+II+III resections, and Type I+II+III+IV resections. Of those, 21% (10 of 48) were treated primarily with a cone prosthesis, 13% (6 of 48) were treated without femoral reconstruction, 10% (5 of 48) were treated with resection without reconstruction, and 6% (3 of 48) had a THA on the sacrum, leaving 50% (24 of 48) of patients who were treated with femoral and acetabular reconstruction using extracorporeally irradiated autograft and total hip replacement; those patients were potentially eligible for this study. During that time span, we used this approach in all Type II pelvic resection procedures, when a part of the hemipelvis could be preserved without resection (other than Type I+II+III+IV) and where we predicted that there would be sufficient bone stock after tumor removal. Of those, 21% (5 of 24) were lost to follow-up before 2 years, and 13% (3 of 24) died within 2 years with the reconstruction intact and without any reoperation or graft loss, leaving 67% (16 of 24) for analysis here. Demographic characteristics, type of tumor, tumor origin site, type of applied resection, and extent of applied surgical procedure were noted. Of 16 patients, 12 were male, with a mean age of 38 +/- 21 years. Tumor types included chondrosarcoma in eight patients, malignant mesenchymal tumor in four patients, osteosarcoma in two patients, and Ewing sarcoma in two patients. Among these, 10 patients had tumors originating from the pelvis, whereas six patients had tumors originating from the proximal femur. We used a Kaplan-Meier estimator to calculate survivorship free from total or partial graft removal at 72 months. To measure functional results, the Musculoskeletal Tumor Society (MSTS) scoring system was utilized at most recent follow-up so as to be able to evaluate the impact of complications (if any) on the ultimate result. The MSTS score ranges from a minimum of 0 points to a maximum of 30 points, where a higher score reflects lower pain and higher functional and emotional capacity. Related complications, time of complications, secondary interventions, and mortality rates were also ascertained from chart review. ResultsGraft survival rate at 72 months after initial reconstruction, free from partial or total graft removal, was 50% (95% CI 26% to 75%). Kaplan-Meier analyses revealed estimated mean time of graft removal as 43 months (95% CI 28 to 58). The graft was protected in eight patients on their final follow-up radiographs. The median (range) MSTS score was 18 (6 to 25) of 30 points at most-recent follow-up (these scores include patients who have had their grafts removed). In all, 15 of 16 patients had 17 complications; 16 were major complications (defined as those substantial enough to result in further surgery or a life- or limb-threatening event). A total of 14 of those 15 patients underwent one or more secondary procedures (a total of 21 unplanned additional procedures were performed in those patients). Deep infection was the most common complication, occurring in eight patients. Prosthesis dislocation occurred in four patients. Three patients developed aseptic acetabular component loosening, two had graft fractures, and one patient developed heterotopic ossification.ConclusionComposite reconstruction with extracorporeal irradiated autografts plus total hip replacement is a feasible reconstruction technique after Type II pelvic resections, although complications and reoperations were common. Although no reconstruction technique has been proven superior to other alternatives, the high risk of complications and reoperations associated with this technique should be considered when selecting from among possible alternative reconstruction methods.Level of EvidenceLevel IV, therapeutic study.

    Management of Chondroblastoma in Pediatric Patients: 21 Years of Single-Center Experience
    (Mdpi, 2024) Tosyali, Hakan Koray; Kaya, Huseyin; Kececi, Burcin; Sabah, Dundar
    Background: Chondroblastoma (CB), a rare benign bone tumor that produces chondrocytes, often develops in the epiphysis or apophysis of children and young adults. The treatment of these rare tumors is complex. The standard treatment protocol involves curettage with local adjuvants and bone graft or cement application. The authors examined 38 CBs to determine risk factors for local recurrence, complications, and functional outcomes following epiphyseal curettage. Methods: Twenty-two girls and sixteen boys aged 10 to 17 years with histologically confirmed chondroblastoma who arrived at our hospital between January 2000 and June 2021 were reviewed retrospectively. Clinical data, radiographic images, histological results, treatment, functional outcomes, and the local recurrence rate were examined-surgical treatment involved total tumor curettage, followed by bone grafting and adjuvant techniques. Local recurrences have also been reported. Results: The most frequently affected site was the proximal femur. Sites of involvement included the proximal femur in 10 (26.3%) cases, the proximal tibia in 8 (20.8%), the humerus in 5 cases (13.2%), the distal tibia in 4 cases (10.5%), the distal femur in 3 cases (7.9%), the supracetabular region in 3 cases (7.9%), the talus in 1 case (2.6%), the calcaneus in 1 case (2.6%), the scapula in 1 case (2.6%), the lumbar spine in 1 case (2.6%), and the iliac bone in 1 (2.6%) patient. The mean follow-up was 144.2 months (24 to 276). The local recurrence rate was 7.9%. The mean Musculoskeletal Tumor Society (MSTS) score was 28.3 points (17 to 30). The mean duration of symptoms at presentation was 5.8 (range, 1 to 28) months. Conclusion: Aggressive curettage and bone grafting resulted in local control and good outcomes in most pediatric patients. In a relatively small proportion of cases, long-term complications and recurrence can occur due to growth plate damage and late diagnosis. In patients admitted to the pediatric clinic with pain, which is often accompanied by localized edema and joint effusion, early detection via advanced radiological scans (X-ray, CT, or MRI) may prevent delays in diagnosis.

    Surgical treatment of displaced radial neck fractures in children with metaizeau technique: Late-term results Metaizeau technique : Late term results
    (Bayrakol Medical Publisher, 2022) Tosyali, Hakan Koray; Hancioglu, Sertan; Kaya, Huseyin; Okcu, Guvenir; Aktuglu, Kemal
    Aim: in this study, we aimed to analyze the functional and radiological outcomes of displaced radial neck fractures in children treated with the Metaizeau technique . Material and Methods: This was a retrospective study, and data were collected prospectively. Thirty-eight patients with grade III and grade IV radial neck fractures according to the classification of Judet et al were managed surgically by Metaizeau technique. All patients were surgically treated with percutaneous k-wire leverage reduction and retrograde transphyseal k-wire fixation. The functional results were evaluated using the Metaizeau functional scoring system. Clinical evaluation and results were performed using the Mayo elbow performance score (MEPS), ROM of the elbow (flexion, extension) and forearm (supination, pronation) was measured with a goniometer. Complications were also evaluated. Results: The average follow-up time was 64.9 months (28 -120 months), there were no patients with nonunion, avascular necrosis, infection, posterior interosseous nerve (PIN) injury, heterotopic ossification or radioulnar synostosis. There were 31 (88.5 %) excellent or good results and 4 (11.5 %) fair results according to the Metaizeau classification. The final X-rays showed fracture healing in all patients. No patient developed complications. Discussion: Intramedullary pinning, as described by Metaizeau, is a reliable and reproducible surgical method to treat radial neck fractures in children, which provides excellent or good results and has a low risk of complications.
