Then, three cannulated screws (3CS), dynamic hip screws (DHS), dynamic hip screws combined with an anti-rotation screw (DHS + ARS), one-hole femoral neck system (1HFNS), and two-hole femoral neck system (2HFNS) were assembled with the reduction models, respectively, to simulate the internal fixation surgical procedure. All models had a load of 2100 N in line with the femoral mechanical axis applied. The implant stress, the head and implant displacements, and the rotational angles of all models were recorded and analyzed.Compared to 3CS and 2HFNS, 1HFNS had higher implant stress (higher than 92.5 MPa and 46.3 MPa, respectively) and displacement (higher than 0.9 mm and 0.8 mm, respectively) in the anatomical reduction. 2HFNS exhibited the highest stress values (225.5 MPa) in the anatomical reduction but the lowest values (159.8 MPa) in the positive buttress reduction when compared to the other implants. 2HFNS showed the best rotational stability in the negative and positive buttress reduction (rotational angels of 0.8° and 0.6°, respectively).Based on the outcome of this computational study, it might be concluded that 2HFNS was an alternative fixation for the treatment of Pauwels type III femoral neck fracture, especially when anatomical reduction cannot be perfectly attained. More relevant clinical and biomechanical studies are needed in the future.","PeriodicalId":94274,"journal":{"name":"Zeitschrift fur Orthopadie und Unfallchirurgie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140178531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a severe complication with a high risk for poor clinical outcome. The aim of this study was to proof that a salvage algorithm for infected HTO with unstable bone situation leads to an infection-free status and bone union of the osteotomy and that correct limb alignment can be restored with good knee function.The study included seven patients with peri-implant infections following HTO. Infections occurred 83 ± 58.9 days (range: 24-191) after HTO. All patients underwent the \"RESTORE\" algorithm: patients received (1) REmoval of the HTO hardware and extensive debridement; (2) the osteotomy was STabilized with a hexapod external fixator (Taylor Spatial Frame, TSF); (3) the osteotomy gap was Opened; and (4) the alignment was REconstructed using the TSF, aiming for the intended limb alignment of the initial HTO. Patient-reported outcomes were assessed 22-36 months after removal of the TSF.After 24 weeks (range: 11-35), an infection-free status and bone healing were achieved. In all cases, the limb was saved, and the previously targeted mechanical axis of the lower limb was restored. All patients reached full extension of the knee joint and at least 110° of flexion. For KOOS: Symptoms 67.86 ± 18.1, Pain 73.41 ± 16.58, ADL 78.99 ± 21.32, Sports 52.14 ± 25.96, and QoL 41.96 ± 24.66. OKS 35.71 ± 8.8, SF-12 Physical Health 38.89 ± 10.3, and SF-12 Mental Health 46.86 ± 13.76.The \"RESTORE\" algorithm is a safe and effective salvage procedure. The concept allows for saving the limb and obtaining the previously planned limb alignment. Patient-reported outcome measures showed slightly lowered values than healthy samples, but substantially better values than patients awaiting HTO. Due to the possibility of initial full weight-bearing, the risk of higher morbidity caused by immobilization is minimized.","PeriodicalId":94274,"journal":{"name":"Zeitschrift fur Orthopadie und Unfallchirurgie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140051433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to compare the short- to medium-term clinical and radiological results among patients diagnosed with an acetabular fracture involving the posterior wall, with or without dislocation.Seventy-nine patients diagnosed with an acetabular fracture involving the posterior wall were retrospectively divided into posterior dislocation and non-dislocation groups. All fractures were open reduction + internal fixation with a plate screw combination through the single Kocher-Langenbeck approach. The short- to medium-term radiographic outcomes of follow-up were evaluated using the Matta radiologic grading system, while the clinical outcomes were evaluated using the modified Merle d'Aubigné-Postel evaluation system.The mean follow-up duration for all patients was 43.90 (range 24-75) months. Both groups achieved similar short- to medium-term clinical and radiographic results. There seems to be no significant differences between the two groups regarding the short- to medium-term assessment of clinical and radiographic results and the occurrence of postoperative complications (p > 0.05).In patients with acetabular fractures involving the posterior wall, hip dislocation is probably not an absolute determinant of a poor outcome. Even with early reduction, the short- to medium-term prognosis results appear similar to those of patients without dislocation.","PeriodicalId":94274,"journal":{"name":"Zeitschrift fur Orthopadie und Unfallchirurgie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139998791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
