RESUMO
PURPOSE: The associated damage to articular cartilage in anterior cruciate ligament (ACL) injured patients is a well-recognized phenomenon; however, there is a relative paucity in the literature regarding the different treatment techniques and outcomes. The purpose of this systematic review was to identify patients treated for acute ACL rupture and associated cartilage injury, with interest in the surgical management of these chondral injuries and any difference in patient-reported outcome measures (PROMs) differing techniques. METHODS: A systematic review was performed looking for treatment or management of International Cartilage Repair Society grade 3 or 4 articular cartilage injury at the time of ACL reconstruction. RESULTS: Seventeen studies fit the criteria, a total of 892 patients were included, 64.6% were male with a mean age of 33.7 and the average time to follow-up was 41.7 months. 68.2% of the lesions were on the medial femoral condyle (MFC) with a mean lesion size of 3.9 cm2. Six different operative methods of dealing with chondral lesions were identified, there was no significant difference in PROMs between the techniques, although there was a significant difference between the preoperative and postoperative outcome measures. CONCLUSIONS: The systematic review found that chondral defects on the MFC are more common in concomitant ACL injuries, despite the pattern of bone bruising being more common on the lateral femoral condyle as reported in the literature. It also found no significant difference in the PROMs between the six different techniques identified for the concomitant management of ACL reconstruction and chondral defects. LEVEL OF EVIDENCE: Level II.
RESUMO
OBJECTIVES: Knowledge of Candida spondylodiscitis is limited to case reports and smaller case series. Controversy remains on the most effective diagnostical and therapeutical steps once Candida is suspected. This systematic review summarized all cases of Candida spondylodiscitis reported to date concerning baseline demographics, symptoms, treatment, and prognostic factors. METHODS: A PRISMA-based search of PubMed, Web of Science, Embase, Scopus, and OVID Medline was performed from database inception to November 30, 2022. Reported cases of Candida spondylodiscitis were included regardless of Candida strain or spinal levels involved. Based on these criteria, 656 studies were analyzed and 72 included for analysis. Kaplan-Meier curves, Fisher's exact, and Wilcoxon's rank sum tests were performed. RESULTS: In total, 89 patients (67% males) treated for Candida spondylodiscitis were included. Median age was 61 years, 23% were immunocompromised, and 15% IV drug users. Median length of antifungal treatment was six months, and fluconazole (68%) most commonly used. Thirteen percent underwent debridement, 34% discectomy with and 21% without additional instrumentation. Median follow-up was 12 months. The two year survivorship free of death was 80%. The two year survivorship free of revision was 94%. Younger age (p = 0.042) and longer length of antifungal treatment (p = 0.061) were predictive of survival. CONCLUSION: Most patients affected by Candida spondylodiscitis were males in their sixties, with one in four being immunocompromised. While one in five patients died within two years of diagnosis, younger age and prolonged antifungal treatment might play a protective role.

INTRODUCTION: In the USA, lumbar discectomy is one of the most commonly performed spinal procedures. As certain sports are considered to be major risk factors for disc herniation, the question remains as to when highly active patients should return to their previous level of activity. This study aimed to analyze spine surgeons' opinions on when patients may return to activities following discectomy as well as their underlying rationale for their decision. METHODS: A questionnaire was designed by five different fellowship-trained spine surgeons for the 168 members of the Spine Society of Australia. Questions on the surgeons experience, decision making, preferred surgical technique, the postoperative rehabilitation and the response to patient expectations were included. RESULTS: In total, 83.9% of surgeons discuss the postoperative level of activity with their patients. Sport is considered as an important contributor for good functional outcome by 71.0% of surgeons. Surgeons recommend avoiding, often permanently, weightlifting (35.7%) of the time, rugby (21.4%), horseback riding (17.9%) as well as martial arts (14.3%) postoperatively even with previous training. The return to high levels of activity is considered as a major risk factor for disc herniation recurrence by 25.8% of surgeons. Return to high level of activity is typically recommended after 3 months by 48.4% of surgeons. CONCLUSION: So far no consensus on the rehabilitation protocol and return to level of activity exists. Recommendations depend on personal experience as well as the individuals' training, and typically, a period of avoidance of sport for up to 3 months is recommended. LEVEL OF EVIDENCE: Level III, therapeutic and prognostic study.

INTRODUCTION: The incidence of acetabular fractures has increased significantly in recent years due to demographic change. It can be divided into high-energy acetabular fractures primarily seen in adult patients versus geriatric patients mostly suffering from low-energy trauma. Historically, acetabular fractures have been treated either non-operatively or surgically following open reduction and internal fixation (ORIF), whereas nowadays total hip arthroplasty (THA) provides a true alternative. Aim of this study was to perform a systematic review on the outcome following THA in acute acetabulum fractures. METHODS: PubMed/MEDLINE, Cochrane and Google databases were systematically searched on December 9, 2021. The key terms were [acetabular fracture] AND [[arthroplasty] OR [fixation]]. All retrospective and prospective original studies in English and German were analyzed the outcome following THA in acute acetabulum fractures were included. RESULTS: A total of 2459 studies were screened, which includes 15 studies that met the inclusion criteria with a total of 590 patients at a mean age of 61.3 years (SD 11.48). Most studies described good to excellent results. Especially, THA allows elderly patients quicker mobilization and rehabilitation as well as symptomatic relief, as compared to ORIF or non-operative treatment. Patients who underwent non-operative treatment showed better results compared to those who underwent ORIF initially. CONCLUSION: In acetabulum fractures, THA provides a good alternative with very good results when patients are carefully selected. Good to excellent outcomes are reported for both acute and delayed use of THA in elderly patients. LEVEL OF EVIDENCE: Level 2, systematic review.

BACKGROUND: Acute isolated syndesmotic injuries (AISIs) have a high potential to be misdiagnosed or underdiagnosed at initial presentation to the hospital. Although magnetic resonance imaging (MRI) is the gold standard in noninvasive diagnostics, it is not always available immediately and is much more expensive than other imaging modalities. This study identifies improvements in conventional radiography and computed tomography (CT) to diagnose AISI and aims to reduce the number of MRI scans needed to verify the diagnosis. METHODS: A retrospective case match control study was conducted by searching our trauma database between 2008 and 2022. A study group of patients with AISI (n = 64) and a control group of patients without AISI (n = 76) were formed to generate an equal number of images from both groups (62 radiographs and 22 CT scans). A total of 16 parameters that quantify the distal tibiofibular relation in injured and uninjured ankles were analyzed. For statistical analysis, a two-sided t-test was applied to calculate significant differences (p < 0.05). In a further step, a receiver operating characteristic curve (ROC) was used to determine cut-off values for the most significant parameters. RESULTS: The most significant measurement (p < 0.001) on axial CT scans was the syndesmotic area (SA). The ROC curve revealed an area under the curve (AUC) of 0.94 (95% CI 0.86-1.0) and a cut-off value of 71.68 mm2 that shows a sensitivity and specificity of 95.5% and 81.8%, respectively. CONCLUSION: This study suggests that radiographic imaging could represent an equally accurate alternative to MRI. These methods might generate the correct diagnosis faster due to their availability and inexpensiveness. By applying our new cut-off values in a clinical setting, the number of underdiagnosed and untreated unstable syndesmotic injuries could be reduced. LEVEL OF EVIDENCE: III, retrospective comparative study.

INTRODUCTION: Spinal fractures in fused spines such as in ankylosing spondylitis or DISH are typically of type B or C fractures where operative treatment is recommended. The mortality rate in non-operatively treated patients is reported to be 51%. The purpose of this study was to investigate the mortality rate, complication rate and demographics of patients following non-operatively treatment in fused spine injuries. METHODS: Between 2019 and 2021, a retrospective study was conducted including all patients who presented to our trauma center with a spinal fracture of a fused spine. Radiology and patient charts were analyzed for fracture pattern, complications, neurological deficit, comorbidities, and mortality rate. RESULTS: A total of 49 patients were found at a mean age was 79.8 ± 10.9 years and primarily males were affected in 65.3%. All fractures were of type B and the thoracic spine was involved in 85.7%. The mean follow-up was 6.3 ± 8.2 months and fusion was obtained in all patients. No neurological deficit was observed in any. A total of 13 patients died at a mean age of 86.5 ± 10.0 years after 157.1 ± 158.1 days. 6 patients (10.2%) deceased within the first 6 weeks at a mean age of 91.8 ± 3.8 years. One patient each suffered from heart failure, an acute delirium, end stage colon cancer and subdural hemorrhage. CONCLUSION: This study shows that the mortality rate in the first 6 weeks following a fracture in a fused spine is 10.2% for patients above the age of 90 years. Therefore, non-operative treatment should be taken into consideration as the mortality rate in other studies may be overestimated. LEVEL OF EVIDENCE: III, retrospective study.

OBJECTIVE: Exertional rhabdomyolysis results from a breakdown of skeletal muscle cells after intense exercise in otherwise healthy patients, causing increased levels of creatine kinase (CK) or myoglobin, as well as urine dipstick positive for blood, and may result in kidney insufficiency. The aim of this study was to outline the current perspectives of exertional rhabdomyolysis in athletes and subsequent treatment based on the current literature. DATA SOURCES: We searched the MEDLINE/PubMed and Google databases for ([exercise] OR [exertional]) AND rhabdomyolysis following the PRISMA guidelines. All abstracts were reviewed by 2 independent examiners. Inclusion criteria consisted of original articles presenting studies on exertional rhabdomyolysis or exercise-induced rhabdomyolysis with 7 or more cases. All case reports, case series, or editorials were excluded. MAIN RESULTS: A total of 1541-abstracts were screened, leaving 25 studies for final inclusion and analysing 772patients. Especially, young male patients were affected at a mean age of 28.7 years (range 15.8-46.6 years). Most of the athletes performed running, including marathons in 54.3% of cases (n = 419/772), followed by weightlifting in 14.8% (n = 114/772). At the time of presentation, the mean creatine kinase was 31 481 IU/L (range 164-106,488 IU/L). Seventeen studies reported the highest level of CK, which was 38 552 IU/L (range 450-88,496 IU/L). For treatment, hydration was the most common method of choice reported by 8 studies. CONCLUSIONS: Exertional rhabdomyolysis seems to be underestimated, and it is essential to screen patients who present with muscle soreness/cramps and/or dark urine after heavy endurance events to avoid any further complications. LEVEL OF EVIDENCE: II; systematic review.

INTRODUCTION: A devastating complication after total hip arthroplasty (THA) is chronic periprosthetic joint infection (PJI). Most frequently spacers (Sp) with or without antibiotics are implanted in a two-stage procedure even though not always indicated due to unknown pathogen, femoral and acetabular defects or muscular insufficiency. MATERIALS AND METHODS: A retrospective analysis of a prospectively collected database was conducted, analyzing the treatment of 44 consecutive cases with chronic PJI undergoing two-stage revision using a Girdlestone situation (GS) in the interim period between 01/2015 and 12/2018. Diagnostics included intraoperative microbiological cultures, histological analysis, sonication of the initial implant, analysis of hip aspiration, as well as laboratory diagnostics and blood cultures. We analyzed the general and age-group-specific success rate of treatment using GS. Furthermore, we compared our data with the current literature on spacer implantation regarding common complications. RESULTS: In total, 21 female and 23 male patients at a mean age of 59.3 ± 9.6 years were included. Age groups were divided into young, mid-age, and elderly. In most patients, microbiology revealed Staphylococcus epidermidis in 39.1% of cases, following Staphylococcus lugdunensis and Staphylococcus aureus in 10.9% after THA explantation. For histology, Krenn and Morawietz type 2 (infectious type) was diagnosed in 40.9%, type 3 (infectious and abrade-induced type) in 25.0%. With GS, the total cure rate was 84.1% compared to 90.1% (range 61-100%) using Sp as described in the literature. Among age-groups, cure rate varied between 77.8 and 100%. Other complications, which only occurred in the mid-age and elderly group, included the necessity of transfusion in 31.1%, and in total, one periprosthetic fracture was identified (2.3%). CONCLUSION: GS shows an acceptable cure rate at a minimum of 2 years when compared to the cure rate reported in the literature for Sp without major complications. For patients with increased risks for treatment failure using spacer, GS seems to be an alternative for chronic PJI when looking at the success rate of treatment.

Despite the relatively high frequency of Achilles ruptures, there is no general consensus on the optimal treatment method. A general trend toward more patients being treated nonoperatively has emerged recently with the advent of functional rehabilitation. However, much of the recent data on this subject has been highly variable. This systematic review focused on Achilles tendon rupture (ATR) treatment outcomes, with a focus on rerupture and complication rates. This systematic review specifically focused on articles regarding ATR treatment that also included rerupture and complication rates. Treatments were divided into three categories: open minimally invasive, open standard, and nonoperative. Bivariate analyses were performed to compare complication and rerupture rates among pairs of treatment options, as well as between early weight bearing versus immobilization. There was significantly higher complications for minimally invasive compared to nonoperative treatment (risk ratio [RR] = 4.4154; p < 0.05), lower complication rates for minimally invasive compared to open treatment (RR = 0.3231; p < 0.05), and higher complications for open standard compared to nonoperative treatment (RR = 5.6350; p < 0.001). There were significantly lower rerupture rates in minimally invasive compared to nonoperative treatment (RR = 0.4085; p < 0.001), a significantly lower rerupture rate in nonoperative treatment compared to open treatment (RR = 0.2282; p < 0.001), and no significant difference in rerupture rates when comparing minimally invasive to open standard treatment. We found that operative treatment is associated with fewer reruptures and more complications than a nonoperative approach. Minimally invasive surgery appears to be associated with a lower rate of complications than open operative treatment.

INTRODUCTION: Mechanical failure of total hip arthroplasties is a rare but devastating complication. With increasing numbers in primary arthroplasty implantation, revision surgeries are indicated more often. Therefore, understanding the mechanism and the location of failure is essential in determining proper treatment. Aim of this study was to identify mechanical failures of all total hip arthroplasties performed in a major academic center as well as the associated risk factors such as BMI and sports. METHODS: A retrospective trial was conducted using our prospective arthroplasty database. Database was searched for all patients presenting with mechanical failures of total hip arthroplasty (THA) to the emergency department between 2011 and 2019. All medical charts and radiographs as well as surgical reports were analyzed to identify demographics, implant choice in addition to location of failure and subsequent treatment. RESULTS: In total, 13 patients suffering from mechanical total hip implant failure were found. The femoral neck (conus) was broken in four patients, the stem in five cases, one broken inlay, two cup failures and one conus dislocation. The mean BMI was 31.42 ± 5.29 kg/m2 including five patients who have obesity class II. In all cases, revision surgeries were indicated. No structural causes or underlying risk factors such as repeated physical load (i.e. in sports) were identified. CONCLUSION: Implant failure does not seem to correlate with participation in sports or BMI. Catastrophic failure of implants is a technical challenge requiring special extraction instruments that can be difficult even for experienced surgeons. It should be noted that functional outcome is often worse for this group of patients after surgery than comparing against those revised for loosening. LEVEL OF EVIDENCE: III, Retrospective Trial.

STUDY DESIGN: Case report and literature review. OBJECTION: Aim of this study was to summarize the current evidence base behind subacute posttraumatic ascending myelopathy (SPAM) including the epidemiology, presentation, diagnosis, prognosis, and etiology. SUMMARY OF BACKGROUND DATA: SPAM is a rare, potentially fatal disorder which is not attributable to ongoing mechanical instability, syrinx formation, or iatrogenic causes. METHODS: A systematic literature search on SPAM was performed on Medline, Ovid, Cochrane, Embase, and PubMed databases between 1969 and 2021. Cases were reviewed and the findings summarized. Further evidence was reviewed to support the hypothesis that disruption of cerebrospinal fluid (CSF) circulation is the underlying etiology of the condition. RESULTS: It is estimated to occur in 0.4%-0.7% of spinal cord injuries and may have a mortality of up to 10%. The most likely etiology disruption of CSF circulation leading to further damage to the spinal cord presumably through pressure mediated effects such as a reduction in cellular perfusion. CONCLUSION: There is effectively no treatment of this condition, however, with interest developing in monitoring of CSF pressures during spinal cord injury this may help confirm the etiology, and allow the suggestion of therapies such as drains or expansion duraplasty to reduce spinal cord pressures. LEVEL OF EVIDENCE: Level II-case report and systematic review.

Smartphones and their associated applications are used frequently by patients and clinicians alike. Despite the technology being widely accessible, their use to aid in rehabilitation is yet to be adopted. The SARS CoV-2 pandemic has presented an opportunity to expedite their integration given the difficulty patients currently have in accessing healthcare. The aim of this study was to perform a systematic literature review on the use of smartphone rehabilitation applications compared to standard physiotherapy for back pain. We conducted a search of Medline/Pubmed and google databases using the search terms [APP] AND [[Orthopaedic] OR [Neurosurgery]], following the PRISMA guidelines. All prospective studies investigating rehabilitation applications for back pain or following spine surgery were included. A total of nine studies met the inclusion criteria which investigated 7636 patients, of which 92.4% were allocated to the interventional group (n = 7055/7636) with a follow up of 4 weeks to 6 months. All except one study reported on patients experiencing back pain on average for 19.6 ± 11.6 months. The VAS-pain score was presented in all studies without significance between the interventional and control group (p = 0.399 before and p = 0.277 after intervention). Only one research group found significantly higher improvement in PROMs for the application group, whereas the remaining showed similar results compared to the control group. Using application-based rehabilitation programs provides an easily accessible alternative or substitute to traditional physiotherapy for patients with back pain. Given that smartphones are so prevalent in activities in our daily lives, this will enhance and improve rehabilitation if patients are self-dedicated and compliant.
RESUMO
INTRODUCTION: Rigid cervical spine following trauma immobilization is recommended to reduce neurological disability and provide spinal stability. Soft collars have been proposed as a good alternative because of the complications related to rigid collars. The purpose of this study was to perform a systematic review on soft and rigid collars in the prehospital management of cervical trauma. METHOD: A systematic review was performed following the PRISMA guidelines. Search terms were (immobilization) AND (collar) AND ((neck) OR (cervical)) to evaluate the range of motion (ROM) and evidence of clinical outcome for soft and rigid collars. RESULTS: A total of 18 studies met eligibility criteria including 2 clinical studies and 16 articles investigating the range of motion (ROM). Four hundred and ninety-six patients at a mean age of 32.5 years (SD 16.8) were included. Measurements were performed in a seated position in twelve studies. Eight articles reported the ROM without a collar, 7 with a soft collar, and 15 with a rigid collar. There was no significant difference in flexion/extension, bending and rotation following immobilization with soft collars compared to no collar. Rigid collars provided significantly higher stability compared to no collar (p < 0.005) and to soft collars in flexion/extension and rotation movements (p < 0.05). The retrospective clinical studies showed no significant differences in secondary spinal cord injuries for soft collar (0.5%) and for rigid collar (1.1%). One study, comparing immobilization without a collar compared to that with a rigid collar, found a significant difference in neurologic deficiency and supraclavicular nerve lesion. CONCLUSION: Although rigid collars provide significant higher stability to no collar and to soft collars in flexion/ extension and rotation movements, clinical studies could not confirm a difference in neurological outcome.

The purpose of this study was to compare the pre and postoperative radiographic findings and analyze the complication rate with respect to the laterality in periacetabular osteotomy in right-handed surgeons. Satisfaction rate and radiographic findings were prospectively collected between 2017 and 2019 and retrospectively reviewed. For analysis, all measurements of the CT scans were performed by a musculoskeletal fellowship-trained radiologist. Complications were classified into two categories: perioperative or postoperative. All surgeries were performed by three right-hand dominant hip surgeons. A total of 41 dysplastic hips (25 right and 16 left hips) in 33 patients were included. Postoperatively, a significantly lower acetabular index angle on the left side was observed at −2.6 ± 4.3 as compared to the right side at 1.6 ± 6.5 (p < 0.05). The change in Center edge (CE) angle was significantly lower for the left side 13.7 ± 5.5° than on the right side, measured at 18.4 ± 7.3 (p < 0.001); however, the overall CE angle was comparable at 38.5 ± 8.9° without any significant difference between the operated hips (left side at 37.8 ± 6.1° versus right side at 39.0 ± 10.3; p = 0.340). No significant differences in other radiographic measurements or surgical time were observed. For complications, the right side was more commonly affected, which may also explain a higher satisfaction rate in patients who were operated on the left hip with 92.3%. The change in lateral CE angle was significantly lower for the left side and the right hip seems to be predisposed to complications, which correlate with a lower satisfaction rate in right-handed surgeons.
RESUMO
Distal radius fractures are common and account for approximately 14% to 18% of all adult extremity injuries. On rare occasions, ipsilateral elbow dislocation can be observed additionally. However, this can be missed without careful examination, especially in patients experiencing altered mental status. The aim of this study was to analyze the mechanism, level of injury, demographics, and associated injuries in distal radius fracture with ipsilateral elbow dislocation. Between 2012 and 2019, we searched our trauma database for distal radius fracture with ipsilateral elbow dislocation. All patients older than 18 years old were included. Data on demographics, mechanism of injury, level of energy, and subsequent treatment were collected. A total of seven patients were identified. The mean age in this cohort was 68.7 ± 13.3 years old, and the left side was involved in 71.4% of the patients. Females were affected in 85.7% (n = 6/7) of cases, all of whom suffered from low-energy monotrauma at a mean age of 71.5 ± 12.3 years old. One male patient suffered from high-energy trauma (52 years old). Mainly, posterior elbow dislocations were observed (66.7%; n = 4/6). Distal radius fracture patterns, in accordance with the AO classification, included two C2-, two C3-, one C1-, and one B1-type fractures. In the patient suffering from high-energy trauma, the closed distal radius fracture was classified as type C3. Associated injures included open elbow dislocation, ulnar artery rupture, and damage to the flexor digitorum superficialis. Although distal radius fracture with ipsilateral elbow dislocation is thought to be from high-energy trauma, this study shows that most patients were elderly females suffering from low-energy mechanisms. It is important for clinicians to maintain a high level of suspicion for any concomitant injury in this population.
RESUMO
Predisposing factors for CAM-type femoroacetabular impingement (FAI) include acetabular protrusion and retroversion; however, nothing is known regarding development in dysplastic hips. The purpose of this study was to determine the correlation between CAM-type FAI and developmental dysplastic hips diagnosed using X-ray and rotational computed tomography. In this retrospective study, 52 symptomatic hips were included, with a mean age of 28.8 ± 7.6 years. The inclusion criteria consisted of consecutive patients who suffered from symptomatic dysplastic or borderline dysplastic hips and underwent a clinical examination, conventional radiographs and rotational computed tomography. Demographics, standard measurements and the rotational alignments were recorded and analyzed between the CAM and nonCAM groups. Among the 52 patients, 19 presented with CAM impingement, whereas, in 33 patients, no signs of CAM impingement were noticed. For demographics, no significant differences between the two groups were identified. On conventional radiography, the acetabular hip index as well as the CE angle for the development of CAM impingement were significantly different compared to the nonCAM group with a CE angle of 21.0° ± 5.4° vs. 23.7° ± 5.8° (p = 0.050) and an acetabular hip index of 25.6 ± 5.7 vs. 21.9 ± 7.3 (p = 0.031), respectively. Furthermore, a crossing over sign was observed to be more common in the nonCAM group, which is contradictory to the current literature. For rotational alignment, no significant differences were observed. In dysplastic hips, the CAM-type FAI correlated to a lower CE angle and a higher acetabular hip index. In contrast to the current literature, no significant correlations to the torsional alignment or to crossing over signs were observed.
RESUMO
OBJECTIVES: The aim of this study was to investigate the degree to which conventional radiography can represent the acetabular and femoral rotational alignment profile between dysplastic and borderline-dysplastic hips. METHODS: A retrospective trial was conducted including 56 borderline-dysplastic and dysplastic hips at a mean age of 28.9 years (range from 18 to 46). Inclusion criteria consisted of symptomatic patients with hip dysplasia undergoing 2-dimensional radiography as well as computed tomography. On radiography, the lateral center edge angle, acetabular hip index, hip lateralization index, acetabular index angle, and the Sharp angle were measured, and the presence of a crossover sign was noted. In computed tomography, the full rotational profile of the lower limb was measured. RESULTS: Significant correlations were observed in the overall analysis between the anteversion of the acetabulum and the hip lateralization index (mean 0.56, coefficient of regression (CoR) -32.35, p = 0.011) as well as the acetabular index angle with a mean of 11.50 (CoR 0.544, p = 0.018). Similar results were found in the subgroup of dysplastic hips with an acetabular index angle of 13.9 (p = 0.013, CoR 0.74). For the borderline-dysplastic group, no significant correlations between the pelvis radiography and rotational CT were seen. CONCLUSION: Although the femoral and acetabular torsion cannot be predicted from x-rays, the anteversion of the acetabulum correlates with the acetabular index angle, the hip lateralization index, and eventually the beta angle in dysplastic hips. For borderline-dysplastic hips, such results did not show up, which strongly illustrates the need for computed tomography in these cases. KEY POINTS: ⢠Much of the current literature focuses on rotational alignment especially with respect to the femur and tibia in healthy patients, although little is known about the acetabular, femoral, and tibial torsion in dysplastic hips. ⢠This is the first study showing significant correlations between the anteversion of the acetabulum and the hip lateralization index as well as the acetabular inclination angle. Also, it is the first study to provide a mechanism for estimation of the torsion of the acetabulum with plain radiography in dysplastic hips. ⢠In borderline-dysplastic hips, no significant correlation was found, which raises the question if a simple x-ray has enough validity to address the acetabular deformity with surgery.

INTRODUCTION: Hirayama syndrome is likely caused by a forward displacement of the posterior dura during cervical flexion leading to changes in the muscles of the fingers and wrist. The aim of this systematic review was to document the number of reported cases, the necessity of dynamic MRI of the cervical spine and the subsequent treatment. METHODS AND MATERIALS: A systematic review was conducted and the Pubmed/Medbase, Cochrane, Google, Embase and Ovid database were searched for (Hirayama) AND ((disease) OR (syndrome)). A total of 42 studies were included for analysis reporting 2311 patients. RESULTS: The mean age was 20.2 ± 2.26 years and predominantly males (92.8%) were identified. On MRI the "snake eyes" appearance of the spinal cord was present in 27.8% and the typical time between onset of symptoms and diagnosis was 41.5 ± 16.4 months. A variety of different treatments have been reported, although there is no substantial evidence that any of them are superior to observation. CONCLUSION: The delay in diagnosis from initial presentation of symptoms shows that this condition may be underdiagnosed in a variety of cases. Further, this study shows the necessity of either a dynamic MRI in flexion or a static MRI scan in neutral position and in flexion, to identify functional spinal and/or foraminal stenosis for a prompt diagnosis and subsequent treatment.

INTRODUCTION: Intramedullary (IM) fixation is the dominant treatment for pertrochanteric and femoral shaft fractures. In comparison to plate osteosynthesis (PO), IM fixation offers greater biomechanical stability and reduced non-union rates. Due to the minimally invasive nature, IM fixations are less prone to approach-associated complications, such as soft-tissue damage, bleeding or postoperative infection, but they are more prone to fat embolism. A rare but serious complication, however, is implant failure. Thus, the aim of this study was to identify possible risk factors for intramedullary fixation (IMF) and plate osteosynthesis (PO) failure. MATERIALS AND METHODS: We searched our trauma surgery database for implant failure, intramedullary and plate osteosynthesis, after proximal-pertrochanteric, subtrochanteric-or femoral shaft fractures between 2011 and 2019. Implant failures in both the IMF and PO groups were included. Demographic data, fracture type, quality of reduction, duration between initial implantation and nail or plate failure, the use of cerclages, intraoperative microbiological samples, sonication, and, if available, histology were collected. RESULTS: A total of 24 femoral implant failures were identified: 11 IMFs and 13 POs. The average age of patients in the IM group was 68.2 ± 13.5 years and in the PO group was 65.6 ± 15.0 years, with men being affected in 63.6% and 39.5% of cases, respectively. A proximal femoral nail (PFN) anti-rotation was used in 7 patients, a PFN in one and a gamma nail in two patients. A total of 6 patients required cerclage wires for additional stability. A combined plate and intramedullary fixation was chosen in one patient. Initially, all intramedullary nails were statically locked. Failures were observed 34.1 weeks after the initial surgery on average. Risk factors for implant failure included the application of cerclage wires at the level of the fracture (n = 5, 21%), infection (n = 2, 8%), and the use of an additional sliding screw alongside the femoral neck screw (n = 3, 13%). In all patients, non-union was diagnosed radiographically and clinically after 6 months (n = 24, 100%). In the event of PO failure, the placement of screws within all screw holes, and interprosthetic fixation were recognised as the major causes of failure. CONCLUSION: Intramedullary or plate osteosynthesis remain safe and reliable procedures in the treatment of proximal femoral fractures (pertrochanteric, subtrochanteric and femoral shaft fractures). Nevertheless, the surgeon needs to be aware of several implant-related limitations causing implant breakage. These may include the application of tension band wiring which can lead to a too rigid fixation, or placement of cerclage wires at the fracture site.
