- Abstract
Background: The Maisonneuve fracture complex (MFC) is a well-known lower leg injury. However, the optimal treatment is still not clear and there is limited data on concomitant injuries of cartilage. Therefore, the aim of our study was to report the incidence of incidental cartilage injuries and their management in arthroscopic treatment of MFC., Patients and Methods: Between February 2018 and February 2021 all patients presenting with MFC in our department were treated with diagnostic ankle arthroscopy and percutaneous syndesmotic screw or suture-endobutton fixation. In case of instable cartilage, it was debrided and according to the International Consensus Meeting on Cartilage Repair of the Ankle, in grade IV lesions < 10 mm or < 100 mm
2 area the subchondral bone was microfractured., Results: Eighteen patients, 16 male and two female, with a mean age of 48.1 years, were included. In all cases, instability of the distal tibiofibular articulation was confirmed arthroscopically. Injuries of the cartilage were found in 56% of the cases and in 31% of the patients surgical intervention was required. In three talar and one tibial lesion additional arthroscopic bone marrow stimulation with microfracture of the subchondral bone was performed., Conclusions: Ankle arthroscopy is a helpful method to guide fibular reduction and to detect and address associated cartilage injuries. Due to the high rate of chondral lesions, addressing these arthroscopically may contribute to better postoperative results., Level of Evidence: IV., (© 2021. The Author(s).)- Published

- Abstract
Background: A fracture of the calcaneus can be a painful and disabling injury. Treatment modalities may be conservative or operative. Surgical treatment strategies include open reduction and internal fixation (ORIF) techniques, as well as a variety of minimally invasive methods. The aim of this study was to evaluate the treatment options and post-treatment complication rates for intra-articular calcaneal fractures at the Traumacenter Linz over a 9-year period., Methods: All patients with calcaneal fractures treated at the Traumacenter Linz between 2007 and 2015 were included in this study. The patients records were retrospectively reviewed, and the data, including demographic parameters, cause of injury, and the time between injury and operative treatment were analyzed. The number of secondary operative interventions due to soft-tissue complications, hardware removal, and the long-term arthrodesis rate were evaluated., Results: A minimally invasive 2-point-distractor method was used in 85.8% (n = 182) of all operatively managed calcaneal fractures (n = 212) in our department. The majority of the operations (88.7%) were performed within 2 days after the accident. The secondary operation rate resulting from wound complications was 2.7% in the 2-point distractor group and 16.7% in the ORIF group. A secondary arthrodesis was performed in 4.7% (n = 9) of the subtalar joints in the entire study population., Conclusions: Our data supported the assumption that severe wound complications would be less likely to occur after minimally invasive treatment compared to ORIF treatment. The rate of secondary arthrodesis in the study cohort was comparable to that in the literature., Level of Evidence: IV.

- Abstract
Background: Bone stock preservation in total hip replacement is essential to allow for later revisions in an increasingly younger and fitter index patient population. While contemporary modular press-fit acetabular cups lead to rigid fixation with equatorial stress and central osteolysis, more elastic fixation may cause different peri-acetabular bone remodelling. The purpose of this study was to investigate changes in peri-acetabular bone mineral density (BMD) in uncemented elastic fixation with monoblock press-fit cups., Methods: This prospective observational study included 45 patients with monoblock cups. We evaluated peri-acetabular BMD using dual-energy X-ray absorptiometry and reported functional outcomes and complications., Results: At a mean follow-up of 24.2 ± 2.2 months, we found that BMD stabilised in DeLee and Charnley zones I and III and recovered to baseline value in zone II. The mean Harris Hip Scores improved significantly from 56.9 ± 20.0 to 97.2 ± 4.0 (p < 0001). Other than one peri-operative dislocation, we saw no post-operative complications., Conclusions: We found favourable adaptive bone changes with BMD stabilisation in the equatorial zones and recovery to pre-operative values in the central zone. Additionally, excellent clinical outcomes and few prosthesis-related complications strengthened the favourable results of monoblock acetabular cups., Trial Registration: Registration number DRKS00017076.

- Abstract
Background: A lack of data exists on the long-term magnetic resonance imaging (MRI) findings after surgical repair of tibial plateau fractures (TPFs). We evaluated the MRI findings 13 to 31 years after surgical repair of TPFs, focusing especially on the pathological changes in the ligaments, menisci, and cartilage., Methods: Twenty-three patients with 24 TPFs underwent open reduction and internal fixation with the same fork-shaped surgical plate that was used in our institution until 1999. No patient underwent preoperative or immediately postoperative MRI. The knees of all patients who underwent plate removal were examined by axial, coronal, and sagittal MRI. The Knee Injury and Osteoarthritis Outcome Score (KOOS) and whole-organ magnetic resonance score (WORMS) were determined in all patients., Results: All 24 knees exhibited MRI abnormalities. An unexpectedly high number of pathological changes in the menisci and ligaments were observed. No meniscal or ligamentous injuries were documented at the time of the injury or initial surgery, but meniscal injuries manifested in the long term. MRI in almost all cases showed a damage to the lateral meniscal, the severity of which was related to the degree of tibial plateau widening, but not to the severity of the lateral joint surface impression. The overall condition of the knee joint was satisfactory as measured by the WORMS, and there was a weak correlation between WORMS and KOOS.

- Abstract
Background: Acute compartment syndrome (CS) of the paravertebral muscles without external trauma is rarely reported in literature. Not all of clinical symptoms for CS are applicable to the paravertebral region., Case Presentation: A 30-year-old amateur rugby player was suffering from increasing back pain following exertional training specially targeting back muscles. He presented with hardly treatable pain of the lumbar spine, dysaesthesia of the left paravertebral lumbar region as well as elevated muscle enzymes. Magnetic resonance imaging (MRI) showed an edema of the paravertebral muscles. Compartment pressure measurement revealed increased values of 47 mmHg on the left side. Seventy-two hours after onset of back pain a fasciotomy of the superficial thoracolumbar fascia was performed. Immediately postoperatively the clinical condition improved and enzyme levels significantly decreased. The patient started with light training exercises 3 weeks after the operation., Conclusions: We present a rare case of an exercise-induced compartment syndrome of the paravertebral muscles and set it in the context of existing literature comparing various treatment options and outcomes. Where there is evidence of paravertebral compartment syndrome we recommend immediate fasciotomy to prevent rhabdomyolysis and further consequential diseases.

- Abstract
Background: There is a growing tendency for complex proximal humerus fractures (PHF) in osteoporotic patients to be treated with reverse shoulder arthroplasty (RSA). It has been proposed that RSA has more benefits than other treatment options. The aim of our study was to investigate preoperative characteristics as well as clinical and radiological outcomes in patients with complex 3- or 4-part PHF who had undergone primary RSA., Methods: Patients with a minimum follow-up of 6 months who had undergone a primary RSA after 3- or 4-part PHF in the period between 2008 and 2011 were eligible for the study. Clinical records, X-rays and CT-scans were investigated and a clinical examination was performed. Disabilities of the Arm, Shoulder and Hand (DASH) score and Constant-Murley score (CMS) were calculated. Sixteen patients were examined as part of the study. The mean follow-up was 20 months (range 6-42 months). According to Codman-Hertel classification we encountered 15 Hertel "12" and 1 Hertel "8" type fractures., Results: Thirty-two patients (27 female - 84.4%) with a mean age of 72 years underwent operations to treat complex 3- and 4-part fractures of the proximal humerus. Sixteen patients were reexamined. In 14 cases the dominant upper extremity was on the right, in 2 cases it was on the left, in 6 cases the right side was affected and in 10 cases the left side was affected. The mean CMS was 54.8 (range 18-95) and the mean DASH was 37.5 (range 2.9-81). A trend was established between the CMS and dominance of the affected shoulder. The CMS was better if the affected shoulder was on the non-dominant side (p-value 0.051). No statistical difference was noted between age and clinical outcome., Conclusions: Our mid-term follow-up shows satisfying results in terms of the treatment of severe displaced fractures in elderly patients with RSA. RSA can provide immediate relief and good shoulder function in elderly patients. Nevertheless, the question of longevity of these implants remains to be observed.
