The incidence of deep surgical site infections following high tibial osteotomy (HTO) ranges between 0.4 to 4.7%. 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.

The first follow-up treatment recommendation from the DGOU's Clinical Tissue Regeneration working group dates back to 2012. New scientific evidence and changed framework conditions made it necessary to update the follow-up treatment recommendations after cartilage therapy.As part of a multi-stage member survey, a consensus was reached which, together with the scientific evidence, provides the basis for the present follow-up treatment recommendation.The decisive criterion for follow-up treatment is still the defect localisation. A distinction is made between femorotibial and patellofemoral defects. In addition, further criteria regarding cartilage defects are now also taken into account (stable cartilage edge, location outside the main stress zone) and the different methods of cartilage therapy (e. g. osteochondral transplantation, minced cartilage) are discussed.The present updated recommendation includes different aspects of follow-up treatment, starting with early perioperative management through to sports clearance and resumption of contact sports after cartilage therapy has taken place.

Based on a systematic review, the present work analyses factors associated with the rerupture rate or non-healing after superior capsular reconstruction with autologous long biceps tendon in the reconstruction of the rotator cuff of the shoulder.A systematic review of the U.S. National Library of Medicine/National Institutes of Health (PubMed) database and the Cochrane Library was conducted in September 2021 using the PRISMA checklist. Articles were identified and analysed that contained data on the rerupture rate after superior capsular reconstruction with autologous long biceps tendon in reconstruction of the rotator cuff of the shoulder. The aim was to identify factors associated with rerupture or non-healing. The risk of bias was determined using the Newcastle-Ottawa scale.Primarily 86 hits could be generated. Seven articles from 2020 and 2021 met the inclusion criteria and were further analysed in terms of content. The evidence level was III to IV. Follow-up was between 12 (minimum) and 24 to 48 months. The risk of bias was not low. Factors that may be associated with rerupture or non-healing are diabetes mellitus and high-grade fatty degeneration of the subscapularis, infraspinatus, or teres minor as preoperative factors. Age, percent footprint coverage, tear size, symptom duration, number of bundles, acromioplasty performed, and tear configuration were not significant factors. Gender, degree of fatty degeneration of the supraspinatus and lesions of the subscapularis tendon were rated differently.According to the literature, but still currently with short-term observation periods, superior capsular reconstruction with an autologous long biceps tendon is another treatment option in the case of massive tears and elderly patients, if there is no high-grade fatty degeneration of the subscapularis, infraspinatus or teres minor. Diabetes mellitus has an unfavorable prognosis. Additional acromioplasty has so far not been associated with better outcomes.

Die 3. Überarbeitung der S3-Leitlinie Polytrauma/Schwerverletzten-Behandlung wurde unter der Federführung der Deutschen Gesellschaft für Unfallchirurgie (DGU) von insgesamt 26 Fachgesellschaften und Organisationen durchgeführt und stellt eine umfassende Aktualisierung der Handlungsempfehlungen zur Schwerverletzten-Versorgung auf Basis neuer wissenschaftlicher Erkenntnisse und Studien dar. Die Leitlinie enthält 332 Kernempfehlungen unterschiedlicher Empfehlungsgrade und dazugehörige Erläuterungen, die Expertenwissen und über 2400 zitierte Literaturstellen berücksichtigen und somit das höchste Niveau (S3) einer Leitlinie erfüllen. Die Änderungen, insbesondere zur Schockraumalarmierung, sind für den Rettungsdienst von besonderer Bedeutung. Zwei neue Kapitel mit Empfehlungen für die Blutstillung und Schmerzbehandlung in der prähospitalen Versorgung wurden hinzugefügt, insgesamt bleibt die Leitlinie ein wichtiger Standard für Entscheidungsfindungen bei Diagnostik und Therapie von Schwerverletzten.

The treatment of patients with ISJ dysfunction is difficult due to the multifactorial causes of pain and various problems in clarification. Treatment includes physical therapy, corticosteroids, prolotherapy, radiofrequency denervation and sacroiliac joint fusion. A new option for the surgical treatment of ISG dysfunction is the Torpedo implant system. For a safe fusion, only 2 implants are needed, which are available in lengths of 30-50 mm. The new implant system has been tested in pilot studies for efficacy and biocompatibility with good results. For further documentation for the Torpedo implant system, a comparative study against the iFuse system was carried out.Two different implants were used: Group 1: Deltacor Torpedo, Group 2: iFuse implants (Si-Bone). The data generated during admission and subsequent check-ups (VAS, ODI, opioid use) were entered into an evaluation file set up for this purpose. Follow-up appointments were set at 1 month, 3, 6 and 12 months postoperatively.The data of 65 patients were evaluated comparatively. In all comparisons, only very small effect sizes were found with regard to the differences in the decrease in pain intensities, so that equivalent effectiveness of the two methods could initially be postulated from a clinical point of view. Most patients in both groups reported taking opioids to treat pain before surgery. According to the decrease in pain intensity, opioid treatment could be discontinued in some patients after the operation. After 12 months, the number of patients treated with opioids decreases to 23% in group 1 and to 17% in group 2. The success of the fusions with the two methods can also be proven by image documentation, from which the position of the implants can also be clearly recognised. In no case was there any loosening.Overall, the evaluation of this study allows the conclusion that both implant systems can be successfully used for the treatment of patients with ISJ syndrome. The present results should be confirmed in further comparative studies with the proposed evaluation methods.

Different anatomical variants have been reported for the proximal and distal femur. Given this context, the goal of our study was to answer the following question: Can we also identify different anatomical variants of the proximal humerus?Two hundred anteroposterior (AP) radiographs of the proximal humerus with an equal gender distribution and equal laterality per gender were reviewed. The metaphyseal diameter of the proximal humerus at the level of the anatomical neck (X) and the intramedullary diameter at 10 cm from the apex of the greater tuberosity (Y) were measured. A new ratio was established, based on both measurements (Y/X). Radiographs showed different anatomical variants: type A: Y/X < 0.3, type B: Y/X = 0.3-0.4, type C: Y/X > 0.4. Two observers reviewed the AP radiographs independently and blindly in 2 different sessions.Three different anatomical groups (A, B and C) were identified based on the 25th and 75th percentiles. A higher percentage of type C was observed among females and a higher percentage of type A among males. A high inter-observer reliability was noted, with a Cronbach's alpha of 0.97 (ICC 0.96-0.98). The intra-observer reliability for observer 1 had a Cronbach's alpha of 0.98.A novel radiological classification of the proximal humerus has been established based on 3 different anatomical types (A, B and C). Further studies are needed to establish whether the novel classification system can be used as an indicator for aseptic loosening of cemented or cementless total shoulder arthroplasty.
