Aims. The prevalence of osteoarthritis (OA) associated with instability of the shoulder ranges between 4% and 60%. Articular cartilage is, however, routinely assessed in these patients using radiographs or scans (2D or 3D), with little opportunity to record early signs of cartilage damage. The aim of this study was to assess the prevalence and localization of chondral lesions and synovial damage in patients undergoing arthroscopic surgery for instablility of the shoulder, in order to classify them and to identify risk factors for the development of glenohumeral OA. Methods. A total of 140 shoulders in 140 patients with a mean age of 28.5 years (15 to 55), who underwent arthroscopic treatment for recurrent glenohumeral instability, were included. The prevalence and distribution of chondral lesions and synovial damage were analyzed and graded into stages according to the division of the humeral head and glenoid into quadrants. The following factors that might affect the prevalence and severity of chondral damage were recorded: sex, dominance, age, age at the time of the first dislocation, number of dislocations, time between the first dislocation and surgery, preoperative sporting activity, Beighton score, type of instability, and joint laxity. Results. A total of 133 patients (95%) had synovial or chondral lesions. At the time of surgery, shoulders were graded as having mild, moderate, and severe OA in 55 (39.2%), 72 (51.4%), and six (4.2%) patients, respectively. A Hill-Sachs lesion and fibrillation affecting the anteroinferior glenoid cartilage were the most common findings. There was a significant positive correlation between the the severity of the development of glenohumeral OA and the patient’s age, their age at the time of the first dislocation, and the number of dislocations (p = 0.004, p = 0.011, and p = 0.031, respectively). Conclusion. Synovial inflammation and chondral damage associated with instability of the shoulder are more prevalent than previously reported. The classification using quadrants gives surgeons more information about the chondral damage, and could explain the pattern of development of glenohumeral OA after stabilization of the shoulder. As the number of dislocations showed a positive correlation with the development of OA, this might be an argument for early stabilization. Cite this article: Bone Joint J 2024;106-B(10):1125–1132

Benefits of early stabilization of femoral shaft fractures, in mitigation of pulmonary and other complications, have been recognized over the past decades. Investigation into the appropriate level of resuscitation, and other measures of readiness for definitive fixation, versus a damage control strategy have been ongoing. These principles are now being applied to fractures of the thoracolumbar spine, pelvis, and acetabulum. Systems of trauma care are evolving to encompass attention to expeditious and safe management of not only multiply injured patients with these major fractures, but also definitive care for hip and periprosthetic fractures, which pose a similar burden of patient recumbency until stabilized. Future directions regarding refinement of patient resuscitation, assessment, and treatment are anticipated, as is the potential for data sharing and registries in enhancing trauma system functionality.

Aims. BoneMaster is a thin electrochemically applied hydroxyapatite (HA) coating for orthopaedic implants that is quickly resorbed during osseointegration. Early stabilization is a surrogacy marker of good survival of femoral stems. The hypothesis of this study was that a BoneMaster coating yields a fast early and lasting fixation of stems. Methods. A total of 53 patients were randomized to be treated using Bi-Metric cementless femoral stems with either only a porous titanium plasma-sprayed coating (P group) or a porous titanium plasma-sprayed coating with an additional BoneMaster coating (PBM group). The patients were examined with radiostereometry until five years after surgery. Results. At three months, the mean total translation (TT) was 0.95 mm (95% confidence interval (CI) 0.68 to 1.22) in the P group and 0.57 mm (95% CI 0.31 to 0.83) in the PBM group (p = 0.047). From two to five years, the TT increased by a mean of 0.14 mm (95% CI 0.03 to 0.25) more in the P group than in the PBM group (p = 0.021). In osteopenic patients (n = 20), the mean TT after three months was 1.61 mm (95% CI 1.03 to 2.20) in the P group and 0.73 mm (95% CI 0.25 to 1.21) in the PBM group (p = 0.023). After 60 months, the mean TT in osteopenic patients was 1.87 mm (95% CI 1.24 to 2.50) in the P group and 0.82 mm (95% CI 0.30 to 1.33) in the PBM group (p = 0.011). Conclusion. There was less early and midterm migration of cementless stems with BoneMaster coating compared with those with only a porous titanium plasma-sprayed coating. Although a BoneMaster coating seems to be important for stem fixation, especially in osteopenic patients, further research is warranted. Cite this article: Bone Joint J 2022;104-B(6):647–656

Aims. It has been generally accepted that open fractures require early skeletal stabilization and soft-tissue reconstruction. Traditionally, a standard gauze dressing was applied to open wounds. There has been a recent shift in this paradigm towards negative pressure wound therapy (NPWT). The aim of this study was to compare the clinical outcomes in patients with open tibial fractures receiving standard dressing versus NPWT. Methods. This multicentre randomized controlled trial was approved by the ethical review board of a public sector tertiary care institute. Wounds were graded using Gustilo-Anderson (GA) classification, and patients with GA-II to III-C were included in the study. To be eligible, the patient had to present within 72 hours of the injury. The primary outcome of the study was patient-reported Disability Rating Index (DRI) at 12 months. Secondary outcomes included quality of life assessment using 12-Item Short-Form Health Survey questionnaire (SF-12), wound infection rates at six weeks and nonunion rates at 12 months. Logistic regression analysis and independent-samples t-test were applied for secondary outcomes. Analyses of primary and secondary outcomes were performed using SPSS v. 22.0.1 and p-values of < 0.05 were considered significant. Results. A total of 486 patients were randomized between January 2016 and December 2018. Overall 206 (49.04%) patients underwent NPWT, while 214 (50.95%) patients were allocated to the standard dressing group. There was no statistically significant difference in DRI at 12 months between NPWT and standard dressing groups (mean difference 0.5; 95% confidence interval (CI) -0.08 to 1.1; p = 0.581). Regarding SF-12 scores at 12 months follow-up, there was no significant difference at any point from injury until 12 months (mean difference 1.4; 95% CI 0.7 to 1.9; p = 0.781). The 30-day deep infection rate was slightly higher in the standard gauze dressing group. The non-union odds were also comparable (odds ratio (OR) 0.90, 95% CI 0.56 to 1.45; p = 0.685). Conclusion. Our study concludes that NPWT therapy does not confer benefit over standard dressing technique for open fractures. The DRI, SF-12 scores, wound infection, and nonunion rates were analogous in both study groups. We suggest surgeons continue to use cheaper and more readily available standard dressings.

Aims. The timing of surgical fixation in spinal fractures is a contentious topic. Existing literature suggests that early stabilization leads to reduced morbidity, improved neurological outcomes, and shorter hospital stay. However, the quality of evidence is low and equivocal with regard to the safety of early fixation in the severely injured patient. This paper compares complication profiles between spinal fractures treated with early fixation and those treated with late fixation. Methods. All patients transferred to a national tertiary spinal referral centre for primary surgical fixation of unstable spinal injuries without preoperative neurological deficit between 1 July 2016 and 20 October 2017 were eligible for inclusion. Data were collected retrospectively. Patients were divided into early and late cohorts based on timing from initial trauma to first spinal operation. Early fixation was defined as within 72 hours, and late fixation beyond 72 hours. Results. In total, 86 patients underwent spinal surgery in this period. Age ranged from 16 to 88 years. Mean Injury Severity Score (ISS) was higher in the early stabilization cohort (p = 0.020). Age was the sole significant independent variable in predicting morbidity on multiple regression analysis (p < 0.003). There was no significant difference in complication rates based on timing of surgical stabilization (p = 0.398) or ISS (p = 0.482). Conclusion. Our results suggest that these patients are suitable for early appropriate care with spinal precautions and delayed definitive surgical stabilization. Earlier surgery conferred no morbidity benefit and had no impact on length of stay. Cite this article: Bone Joint J 2020;102-B(5):627–631

Aim

There is not adequate evidence to establish whether external fixation (EF) of pelvic fractures leads to a reduced mortality. We used the Japan Trauma Data Bank database to identify isolated unstable pelvic ring fractures to exclude the possibility of blood loss from other injuries, and analyzed the effectiveness of EF on mortality in this group of patients.

Introduction:. Early stabilization has the potential to expedite early return to function and reduce hospital stay thus reducing cost to health care. A clinical audit was performed to test the hypothesis that early surgical stabilization lowers the rate of soft tissue complications and is not influenced by choice of distal fibular implants used for stabilization of ankle fractures. Methods:. All surgically treated adult patients with isolated unstable ankle fracture were included from April 2012 to April 2013 at a MTC in UK. Patients with poly-trauma were excluded. All patients underwent a standard surgical protocol: aim for early definitive surgical fixation (ORIF) within 24 hours however if significantly swollen than temporary stabilization with an external fixation followed by a staged definitive fixation. Results:. In total 172 consecutive unstable ankle fractures were included in one-year study period. Definitive fixation (ORIF) was achieved in 91% patients with only 9% patients required temporary stabilization with external fixation. Fibular locking plates were used in 59(38%) patients compared to conventional one-third tubular plates in 91(60%) patients. In ORIF group 42% (73) patients were operated within 24 hours of admission whilst 58% (83) under went early fixation after 24–72 hours. At one year follow up complications were recorded in 18(11%) patients including metal irritation requiring removal of implant in 6(4%) patients. Wound complications and deep infection leading to a further surgical procedure in 8(5%) patients. There was no statistical difference between complication rates (p=0.016) in early versus delayed fixation groups. Fibular locking plates were associated with higher soft tissue complications (13%) as compared with conventional plates (2%) (p=0.004). Conclusion:. Our study showed that the timing of the surgery has less influence on the complications of the ankle fracture fixation. However choice of implants requires careful consideration and we suggest caution against use of current fibular locking plates

Purpose: The optimal timing for surgical stabilization of the fractured spine is controversial. Early stabilization facilitates earlier mobilization and theoretically reduces associated complications. Method: Consecutive patients requiring stabilization surgery for a spinal fracture, without neurological injury were identified from a prospective institutional database. Patients were stratified by the time to their final surgical stabilization procedure (< 12, 12–24, 24–48, 48–72 and > 72 hours) and outcomes compared. Multivariate analyses were performed to explore potential confounding effects. Results: 76 patients satisfied the inclusion/exclusion criteria. The median time to final surgical spinal stabilization was 71.8 hours. There were significant differences in complications related to prolonged recumbancy (e.g. respiratory failure, thromboembolism, p = 0.016) between the different time frames. Graphical exploration suggested higher complication rates after 48 hours delay. Comparing patients stabilized after 48 hours compared to those within, there was a 6.9 times (p = 0.0085) greater risk of a complication related to prolonged recumbancy. These effects remained significant after multivariate adjustments for age, comorbidity and ISS. There were trends towards longer lengths of stay and lower function (measured using the FIM) at discharge in the surgical delay group. Conclusion: This study demonstrates a strong relationship between surgical delay and complications. The cutoff for this delay appears to occur at 48 hours. This study is limited in that the identified relationship may be related to a number of other confounding factors not measured or inadequately adjusted for because of small numbers. Further study, using this study’s developed algorithms in larger datasets, may help resolve some of these issues

Introduction and Objectives: According to the literature, the prevalence of osteoarthritis in shoulder instability is about 4 to 31%. In these studies we used imaging techniques with little sensitivity to early alterations of cartilage. The aim of this study is to arthroscopically assess the prevalence and distribution of osteoarthritis in shoulder instability and analyze associated risk factors. Materials and Methods: In a group of 64 patients (mean 28.9 years of age, range 15–55) we arthroscopically assessed the degree and distribution of glenohumeral arthritis at the time of surgical stabilization classifying them into 3 groups according to severity. We determined the correlation of the degree of osteoarthritis (Pearson coefficient) with sex, dominance, age, age at the first episode, preoperative sports activities, degree of instability, laxness and number of dislocations and subluxations. Results: 63 patients (98.5%) had chondral or synovial lesions of a degree of severity categorized as slight, moderate or severe in 26 (40.6%), 35 (54.7%) and 3 (4.7%) patients respectively. The most frequent findings were Hill-Sachs type lesions and anteroinferior glenoid fibrillation. We found a significant correlation between degree of severity of the arthritis (p< 0.05) and the age of the patient, age at the first dislocation and number of dislocations. Discussion and Conclusions: The prevalence of osteoarthritis in shoulder instability is greater than has been described. The fact that there is a positive correlation between the number of dislocations suffered and the severity of the arthritis could be a reason for carrying out early stabilization in these patients

Early fracture stabilization has been shown to reduce morbidity and mortality in the patient who is multiply injured. Controversy exists in terms of managing multiple trauma patients who sustain thoracic injuries along with femoral shaft fractures. The purpose of the present study was to determine whether the presence and treatment of femoral shaft fractures increases morbidity in patients with pulmonary contusions and to determine the effect of patient and surgical factors on outcome. Patients that suffered chest injuries between January 1987 and April 2006 were identified from the prospectively collected trauma databases at two hospitals. Patient records were reviewed to verify all data. The diagnosis of pulmonary contusion was confirmed with radiologic or post-mortem investigations. All relevant patient and surgical data was collected. Exclusion criteria included severely injured patients (head/abdomen AIS> 3), age sixty years, death twenty-four hours after injuries occurred. A total of 1190 patients with confirmed pulmonary contusions met inclusion criteria; there were 113 femoral shaft fractures (five bilateral). Patients in both the isolated pulmonary contusion and pulmonary contusion with femoral fracture had similar injury severity scores (ISS) and demographic information. Fractures were reduced with intramedullary nailing in 88% of cases. Mean age was thirty-five years. There were significantly more incidences of fat embolism syndrome and acute lung injury (ALI) in patients with femoral factures (twenty-four hours following the injury had significantly greater risk of developing ARDS (p< 0.05). The presence of femoral shaft fractures in patients with pulmonary contusions increases the duration of admittance to hospital and can lead to higher rates of fat embolism syndrome and ALI, however it does not appear to impact overall mortality or contribute to the development of other common respiratory complications. Early reduction of shaft fractures is encouraged to further decrease complications

We have reviewed the patients with vertical shear fractures of the Pelvis and report on our treatment protocol and long-term functional outcome. Methods: Between January 1993 and January 2002, out of 581 pelvic ring injuries treated in our unit, we identified 31 vertical shear fractures in 29 (4.9%) patients (4 female). Data such as age, sex, aetiology, associated injuries, ISS, resuscitation and transfusion requirements were recorded. ICU/HDU stay, surgical stabilization, urological injuries, systemic complications, neurological injury and mortality were recorded and analysed. Functional outcome was assessed using the following generic tools: EuroQol EQ-5D, SF36v2, SMFA, Majeed score and VAS. Results: The mean age was 43.5 (16–71). The median ISS was 22 (12–32). Motorcycle accidents were responsible for 27%. Associated injuries included the chest (12 patients), abdomen (8 patients) and extremities (14 patients). Urethral injury was present in 9 and ruptured viscus was identified in 3 patients. Neurologic deficit was present in 9 cases. Posterior ring was stabilized in 3 (0 – 13) days. 6 patients developed systemic complications – ARDS in 4 (12%) patients, sepsis in 2 (6%). The mean follow up was 39 (12–101) months. Functional outcome using the Majeed score revealed that one-third of the patients were fair. SF-36 (physical and mental scores) and EQ 5-score revealed that one-third of the patients were fair. SF-36 (physical and mental scores) and EQ 5-score revealed that one-third of the patients were fair. SF-36 (physical and mental scores) and EQ 5- D revealed a moderate functional outcome. The SMFA and the visual analogue score also revealed similar outcomes. Conclusion: Prompt resuscitation and early temporarily stabilization of the pelvic ring is essential. Sound reconstruction of the pelvic ring is not always associated with good results, probably due to the extensive pelvic floor trauma seen in this series of patients. Younger individuals seem to have a relatively better outcome when compared to the older age group

Introduction: Early stabilization of the skeleton in multiply injured patients has shown to reduce mortality and chest morbidity. Reamed intramedullary nailing is the current method of choice for stablizing femoral and tibial shaft fracture. However several investigators have highlighted the adverse effect of early reamed nailing in polytrauma patients. Intravasation of medullary fat during canal pressurizaton has been suspected to produce a ‘second hit’ and trigger pneumonia and ARDS. The objective of this study is to investigate the effect of a filter placed into the ipsilateral common iliac vein during medullary canal pressurization. Methods: Using an established model of fat embolization, twelve mongrel dogs were randomized into two groups. Under general anaesthesia, cannulations of carotids and jugular veins and transesophageal echo-cardiography were performed in all animals. Under fluoroscopy control, a special filter was inserted percutaneously into the left common iliac vein in half the animals, where as the other half served as controls. In all dogs, the left knee was exposed; the femor and tiiba were sequentially reamed and then pressurized by injection of bone cement and insertion of intramedullary rods. Hemodynamic measurements and trans-esophageal echocardiography images were recorded continuously during the surgical procedure. After 45 minutes from pressurization, the dogs were sacrificed and the lungs and kidneys were harvested and fixed for histological analysis. Results: There was significant difference noticed in the right-sided pressures and oxygen tension between the filter and the control groups. The mean pulmonary artery pressure at 3 minutes of pressurization was 12mm of Hg in the filter group and 28mm of Hg in the control group. Transesophageal echocardiography showed less embolic shower in the filter group and also lesser dilatation of right ventricles. Histomorphometry with special staining demonstrated much less proportion of lungs to be occupied by fat in the filter group as compared to the control group. Discussion and Conclusion: This canine study has demonstrated that mechanical blockade by a venous filter can significantly reduce the emobilic load on the lungs in an established model of fat embolization. A suitable filter with suction system is being designed for possible use in high-risk patients

Introduction Rheumatoid arthritis also affects the spine and creates conditions that need surgical treatment. As in other parts of the body, the maintenance of function and reduction of pain are primary goals of surgical treatment, however the additional threat to the neurological structures create an additional dimension in the surgical treatment of the spine. Destructive processes of osteoligamentous structures and severe osteoporosis may be blamed as the principle cause for pain, deformity and subsequent neurological deficit in the rheumatoid patient’s spine. Cervical spine Atlantoaxial instability is the most frequently encountered pathology in the cervical spine of the rheumatoid patient. In order to avoid late appearance of myelopathy, the timing of surgery in the presence of significant atlantoaxial instability (ADD < 5mm) has to be carefully evaluated. The tendency is towards early surgical stabilization since no spontaneous improvement is to be expected in cases with aggressive rheumatoid arthritis. Late surgery not only carries the risk of causing myelopathy by repeated micro-trauma of the myelon, but also the need for extensive surgery including the occiput and the lower cervical spine in case of advanced destructive processes. The subaxial cervical spine has a tendency to disintegrate in the presence of aggressive course of rheumatoid arthritis. The extent of instability and site of compression has to be carefully analyzed, using MRI and neurophysiological examinations. Due to weak bone structures anterior and posterior interventions are often necessary. Lumbar spine The rheumatoid pathology in the lumbar spine is mainly influenced by the degree of osteoporosis. Typical osteoporotic fractures, often on several levels, represent the most frequent pathology, which needs surgical help. In case of persistent pain the relatively new technique of vertebroplasty offers an elegant way to reduce pain. If severe deformities occur, the osteoporotic structure of bone limits the surgical possibility of correction of the deformity. Conclusion “Wait and see”-policy in rheumatoid patients with spinal pathology is often not appropriate (as in other joints of the body) if function and neurology should be preserved and maintained. Early surgery represents usually minor intervention and is better tolerated than extensive corrections. Osteoporosis is the main limitation for surgical treatment in the rheumatoid spine

Aims: Functional outcome following pelvic ring fractures is closely correlated with the anatomic results. ORIF is correlated with good anatomic results but with morbidity. Isolated sacro-iliac screws are inadequate. We assessed outcome after complete Minimal-Invasive-Surgery. Methods: Between 1998 and 2001, 21 consecutive patients with unstable pelvic-ring disruptions [15 AO C, 6 AO B] were treated operatively. In a supine position, after close reduction of the fractures, anterior þxation, percutaneous stabilization of the posterior lesions was accomplished using ßuoroscopically-guided ilio-transsacral 7,3 mm cannulated lag-screws inserted through the body of S1 to the opposite sacroiliac joint. Results: Delay from injury to þxation was 4 (0–8) days. 13 anterior þxations and 21 ilio-transsacral cannulated screws were placed. No secondary complications. The main outcome was 2 years; radiographically, 19 anatomic reductions of the posterior fractures and 2 vertical ascensions (5 mm) were achieved. The mean Majeed score was 95. Conclusions: Early stabilization of instable pelvic-fractures in a supine position using percutaneous ilio-transsacral screws and anterior þxation is a technique that lends itself to a variety of unstable pelvic fractures. This diminishes potential blood loss and operative times in multiply injured patients. An obvious limitation in the percutaneous technique is the inability to restore the normal anatomy. Surgical stabilization allows early mobilization of the patients, prevents progressive deformity and obtains good functional results
