Safety and efficacy of silicone tape for indwelling urinary catheter fixation in intensive care patients-A randomized clinical trial.

BACKGROUND: Critically ill patients are more vulnerable to medical adhesive-related skin injuries (MARSI), whose prevention is a constant challenge and one of the main quality indicators of nursing care. MARSI associated with indwelling urinary catheter (IUC) fixation is a relevant adverse event, mainly because of the constant involuntary traction and high skin vulnerability of the fixation site. Silicone adhesive tape has appreciable qualities for fragile skin among the range of adhesives, leading to the inference that it reduces the risk of MARSI. AIM: To compare silicone adhesive tape for IUC fixation with acrylate tape regarding its safety and efficacy. STUDY DESIGN: This was a randomized controlled trial blinded to the patients and evaluator. Data were collected from an intensive care unit (ICU) of a tertiary university hospital in Brazil. Patients with IUC and no MARSI at the fixation site were considered eligible. The omega (Ω) fixation technique was used for IUC fixation. A total of 132 participants were enrolled and divided into two research groups: 66 patients in the intervention group (silicone tape) and 66 in the control group (acrylate tape). Outcomes were the incidence of MARSI, patient outcome in the ICU and hospital and partial, total and overall spontaneous detachment of the tapes. RESULTS: The overall incidence of MARSI was 28%, with 21% in the silicone group and 35% in the acrylate group, with no statistically significant difference (p = .121), including the severity of the lesions (p = .902). However, partial (p = .003) and overall (p < .001) detachment of the tapes were more frequent in the silicone group. CONCLUSIONS: Silicone tape is no safer than acrylate tape for IUC fixation and is less adhesively effective. RELEVANCE TO CLINICAL PRACTICE: There is no evidence to support the extensive use of silicone tape in this context.

Comparison between anterior-to-posterior screw fixation versus posterolateral approach plate fixation for posterior malleous fracture: A systematic review and meta-analysis.

PURPOSE: There are two main surgical fixation methods for the posterior malleolar fractures (PMFs), the anterior-to-posterior (AP) screws or via the posterolateral (PL) approach utilizing a buttress plate. This review aims to compare the clinical outcome between the AP screw fixation and the PL plate fixation for treating PMFs. METHODS: We searched all relevant publications about PMFs treated with AP screws or PL plates through electronic databases including the PubMed, the Cochrane Library, the Embase, the Wiley online library and the Web of Science. The meta-analysis was conducted to evaluated clinical outcomes including reduction quality, post-operative function and complications. RESULTS: Six studies (one single randomized controlled trial and five retrospective cohort studies) were enrolled. 172 patients underwent AP screw fixation and 214 patients underwent PL plate fixation with a total of 386 patients (169 males and 217 females). The PL plating group yielded better AOFAS scores(MD = 6.97, 95 % CI=[4.68, 9.27], P＜0.00001, I2 =0 %) and was more likely to achieve excellent anatomical reduction(OR=5.49, 95 % CI=[1.06, 28.42], P = 0.04, I2 =80 %). No differences were found in the bad reduction quality, incidences of complications (arthritis, neuralgia, superficial wound healing problems and implant failure), the walking VAS scores and the dorsiflexion restriction degrees. CONCLUSION: We suggest that the PL plate fixation method has the clinical benefit of achieving anatomical reduction and better AOFAS scores over the AP screw fixation for treating PMFs. No differences were found in the incidences of complications ( arthritis, neuralgia, superficial wound healing problems and implant failure), the walking VAS scores and the dorsiflexion restriction degrees. The posterior approach and the direct reduction are recommended for the treatment of the PMFs. LEVEL OF CONFIDENCE: Ⅱb.

The reliability of posterior malleolar ankle fracture assessment: a unique perspective.

AIM: This study aims to elucidate the pathology of PMFs in the South African population, establish correlations between fracture patterns and international classification guidelines and evaluate the interobserver reliability of current classifications. METHODS: A retrospective review was conducted in a multicentre analysis over a one-year period from January 2019 to December 2019 at our institution. Computer tomography scans for foot and ankle injuries were reviewed, and posterior malleolus fractures were included. Pathoanatomical data was collected and analysed according to known classification systems and subsequent treatment modalities evaluated. A panel of observers individually reviewed radiographic data to determine interobserver reliability. RESULTS: A total of 71 patients were included with a mean age of 41 ± 13.4 years (range 18-78) and a female predominant population (69%). A greater proportion of injuries were high energy (23.9%), with significant fragment comminution (53.5%), and half (52.1%) of all injuries were subluxated/dislocated at presentation. A total of 93% of injuries were managed operatively, despite theatre access limitations resulting in significant delays to fixation (19.1 days). Despite good pathoanatomical agreement with most international classifications, interobserver reliability was poor (Krippendorff α-coefficient < 0.667). Inconsistent treatment patterns in operative and non-operative strategies are reported. CONCLUSION: A unique patient population of younger, female individuals incurred posterior malleolar fractures due to higher energy mechanisms of injury. Whilst injury patterns were mostly comparable, significant interobserver variability was noted. Resource limitations, diagnostic challenges, poorly defined and inconsistent treatment strategies, inevitably impact outcomes within the South African population. LEVEL OF EVIDENCE: Level III.

Comparison of femoral neck system and three cannulated cancellous screws in the treatment of vertical femoral neck fractures: clinical observation and finite element analysis.

OBJECTIVE: The purpose of this study was to compare the biomechanical and clinical results of two surgical methods for the treatment of vertical femoral neck fractures: Femoral neck system (FNS) and traditional three cannulated cancellous screws (CCS). METHODS: First, we developed three different vertical femoral neck fracture models for the finite element analysis, with angles of 55°, 65°, and 75°, respectively. Two experimental groups were set up: the FNS group and the CCS group. Each fracture group was tested under axial loads of 2100 N to measure the femur's displacement, Von Mises stress (VMS), and its internal fixation components. Secondly, we retrospectively included the cases of vertical femoral neck fractures with FNS and CCS in our hospital from May 2019 to May 2021. In this study, we compared the duration of intraoperative fluoroscopy, operative time, hospital stay, fracture healing time, Hemoglobin loss, Harris score of hip joint function, and postoperative complications among patients undergoing hip joint replacement. RESULTS: In terms of finite element analysis, FNS has better anti-displacement stability than CCS at 55°and 65°, while FNS is greater than CCS in Von Mises stress. Clinically, we followed up on 87 patients for an average of 12 months. FNS was superior to traditional CCS in fracture healing time, operation time, fluoroscopy duration, fracture healing time, and Harris hip function score. CONCLUSION: FNS is superior to traditional CCS in biomechanical and clinical aspects of treating vertical femoral neck fractures. There is potential for FNS to become a new treatment option for vertical femoral neck fractures.

Speeding pelvic fracture fixation: CT scan with simultaneous 3-D pelvic reconstruction in the emergency department.

INTRODUCTION: Contrast-enhanced computed tomography (CT) scans are usually needed in the emergency department (ED) to evaluate intra-abdominal injuries associated with pelvic fractures. Three-dimensional (3-D) images for pelvis reconstruction are also needed for planning surgical fixation after admission. This study investigates the advantages integrating a one-stage computed tomography (CT) scan with these two diagnostic modalities simultaneously to reduce the time to surgery and improve the outcomes of pelvic fracture fixation. METHODS: A retrospective cohort study (2018-2021) of patients with pelvic fractures was performed. Patients were categorized into the one-stage CT group or the two-stage CT group, and propensity score matching was used to address biases. The outcome measures included time to surgical fixation, time to CT scan for 3-D pelvis reconstruction, and overall length of hospital stay. RESULTS: Four hundred forty-four pelvic fracture patients who underwent definite surgical fixation were identified. Of those, 320 underwent a one-stage CT scan, while the remaining 124 underwent a two-stage CT scan. After well-balanced matching, those in the one-stage CT group had a significantly shorter time to surgical fixation than those in the two-stage CT group (4.6 vs. 6.8 days, p < 0.001). Even among critically ill patients necessitating intensive care unit (ICU) admission, the one-stage CT scan group had a shorter time to definitive surgical fixation (5.5 vs. 7.2 days, p = 0.002) and a shorter hospital stay (19.0 vs. 32.7 days, p = 0.006). CONCLUSION: A one-stage contrast-enhanced CT scan combined with simultaneous 3-D pelvis reconstruction is promising for expediting surgical fixation in pelvic fracture patients. This innovative strategy may improve patient outcomes by facilitating timely surgical interventions and minimizing delays associated with additional CT scans.

Is fixation of both clavicle and scapula better than clavicle alone in surgical treatment of floating shoulder injury? A retrospective study.

BACKGROUND & OBJECTIVE: Little research was available to explore which surgical fixation was better between fixation of both clavicle and scapula and clavicle alone in management of floating shoulder injury. METHODS: Total 69 patients with floating shoulder injury receiving surgery from February 2005 to July 2020 participated in the study. 49 patients underwent fixation of the clavicle alone (Group C) while 20 patients underwent fixation of both clavicle and scapula (Group C + S). They were further divided into subgroups according to age: Group C1, Group C + S1 (age ≤ 55 years old) and Group C2, Group C + S2 (age>55 years old). The radiological parameter (glenopolar angle (GPA)) and clinical outcomes (Herscovici score, Constant-Murley shoulder outcome score (CSS score), and Visual Analogue Scale score (VAS score)) were collected and compared between these groups. The correlation between age and radiological parameter and clinical outcomes was calculated by the Spearman correlation analysis. RESULTS: All people were followed up for at least 1 year. The degree of change in GPA before and after surgery in Group C + S is significantly better than that in Group C. The Herscovici and CSS score in Group C + S2 were significantly higher than those in Group C2 at 1 month, 3 months and 1 year after surgery. However, no significant difference in Herscovici and CSS score was found at final follow-up (1 year after surgery) between Group C + S1 and Group C1. The VAS score in Group C + S2 at final follow-up was significantly lower than that in Group C2. No significant difference in VAS score at final follow-up was found between Group C + S1 and Group C1. In addition, the VAS score was negatively correlated with Herscovici and CSS score. No correlation was found between VAS score and GPA. CONCLUSIONS: Both types of surgical fixation are effective in management of floating shoulder injury. For young people with floating shoulder injury, both types of surgical fixation are equally effective. However, for older people with floating shoulder injury, fixation of both clavicle and scapula is better in prognosis than fixation of clavicle alone.

Indications for surgical fixation of low-energy pelvic ring fractures in elderly: a systematic review.

INTRODUCTION: There are no generally accepted criteria for when and how to fixate osteoporotic pelvic ring fractures in elderly. This systemic review aims to summarize the currently available literature regarding the indications and methods for surgical fixation of fragility fractures of the pelvic ring in elderly patients after low-energy trauma. MATERIALS AND METHODS: The Pubmed and Embase databases were searched using the key words pelvic fractures, geriatric, fragility, osteoporosis, and surgical fixation, and their synonyms. Extracted data including the indication, method of operative fixation, and post-operative outcomes (pain levels, mobility, complications and mortality) were analyzed using descriptive statistics. The studies were too heterogeneous to perform a meta-analysis. RESULTS: Eleven cohort studies (3 comparative and 8 noncomparative) were included. The methodological quality was poor to moderate; the studies were heterogeneous regarding study design and reported outcomes. In all included studies operative treatment for all fracture types was preceded by a period of conservative treatment comprising physiotherapy-guided full weight-bearing. Time to surgery differed widely. For posterior ring fixation, the majority of the included studies used minimally invasive surgery with trans-iliosacral screws. Five studies described a form of additional fixation of the anterior pelvic ring but did not report the indications. CONCLUSIONS: Fixation of low-energy pelvic ring fractures in elderly is commonly performed after a period of conservative treatment, with persistent pain as the most frequent indication for fixation. Fracture classification based on stability seems to be of secondary importance. Timing for surgical fixation of the pelvic ring fracture in elderly patients remains diverse. Large well-designed comparative prospective studies and randomized controlled trials are needed to provide clearly substantiated guidelines.

The outcomes of surgical treatment for lateral Hoffa fracture nonunions.

INTRODUCTION: Lateral Hoffa nonunion are rare injuries. A significant percentage of these nonunions are due to missed acute lateral Hoffa fractures. Operative management of these injuries is difficult and complicated by the presence of bone loss, infection, and soft-tissue contractures. In this study, the aim was to assess clinical and functional outcome in our group of patients with lateral Hoffa nonunion who had undergone operative management and to determine whether variables such as fracture type, infection, and previous surgery affect nonunion/complication rates. MATERIALS AND METHODS: Data were analyzed for patients with lateral Hoffa nonunion who underwent surgical fixation from January 2008 to December 2020 at a tertiary-care referral center. Patients with lateral condyle Hoffa nonunion and having a minimal follow-up of 1 year were included in this study. Patients with medial Hoffa nonunion, pathological fractures, and children aged less than 16 years were excluded from the study. The fractures were classified by the AO/OTA and Letenneur classification systems. Clinical and functional outcomes were assessed by the Knee society score (KSS) and the lower extremity functional scale (LEFS). RESULTS: All the 12 patients had united in our series. One patient had reduction failure at 3 months who united after re-fixation. The union rate in our patients was 100%, with a loss of reduction rate of 7.7%, and post-traumatic arthrosis of 7.7%. The average follow-up period was 52.16 ± 27.7 months. The mean knee flexion obtained at the final follow-up was 104.5° (80°-130°). The average KSS clinical score was 80.6 (65-88). The average KSS functional score was 92 (70-100). The average LEFS score was 71 (47-79). There is a statistically significant improvement in the knee range of motion in our patients (p = 0.001). However, no correlation could be detected between variables like type of fracture, infection, and previous surgeries and outcomes. CONCLUSIONS: Lateral Hoffa nonunion can be managed with careful planning of surgical approaches and fixation techniques.

Operative fixation of rib fracture nonunions.

INTRODUCTION: Rib fractures are common injuries in trauma patients that often heal without intervention. Infrequently, symptomatic rib fracture nonunions are a complication after rib fractures. There is a paucity of literature on the surgical treatment of rib fracture nonunion. The purpose of this study was to describe the efficacy of rib fracture nonunion operative fixation with particular focus on surgical technique, healing rates, and complications. MATERIALS AND METHODS: Patients aged ≥ 18 years with symptomatic rib fracture nonunions treated with open reduction and internal fixation (ORIF) with locking plates at a single urban level 1 trauma center were retrospectively reviewed. Pertinent demographic, clinical, radiographic, and surgical data were collected and analyzed. RESULTS: A total of 18 patients met inclusion criteria. The mean time from injury to undergoing ORIF for rib fracture nonunion was just under a year and the number of ribs plated was 2.95 ± 1.16 (1-5 ribs) with bone grafting used in six cases. All patients (100%) showed evidence of healing at an average of 2.65 ± 1.50 months (2-8 months). All patients reported a decrease in pain. No narcotic pain medication was used at an average of 3.88 ± 3.76 weeks (0-10 weeks) post-operatively. Intraoperative and postoperative complications were found in 4 (22.2%) patients. CONCLUSION: This study concluded that operative fixation of symptomatic rib fracture nonunion demonstrated favorable outcomes with reduction in preoperative pain levels, decreased use of narcotic pain medication, minimal complications, and a high rate of fracture union. This described method provides symptomatic relief, reduction in pain, and promotes bony healing of the fracture nonunion without development of major complications. We suggest that operative fixation should be considered as the primary method of treatment of symptomatic rib nonunions.

Fragility fractures of the pelvis in the older population.

Pelvic fractures are an increasingly common injury seen in the older population and represent a significant burden of morbidity and mortality in this age group, as well as a large financial burden on the health service. It is well established that early fixation of femoral neck and acetabular fractures improves outcomes and increases the chances of patients returning close to their premorbid functional baseline. However, fixation of fragility fractures of the pelvis is less well established in current practice. There has been recent development of novel stabilisation techniques for unstable pelvic fractures, designed to tackle the difficulties associated with fixation in poor bone quality, along with medical trials of parathyroid hormone analogue treatment. However, it is still current practice to manage nearly all fragility fractures of the pelvis conservatively. In this article, we consider whether the development of surgical stabilisation techniques for pelvic fragility fractures may have the potential to improve the well-described morbidity and mortality associated with them.

Increase in surgical fixation of pediatric midshaft clavicle fractures since 2008.

BACKGROUND: Clavicle fractures in children have traditionally been treated non-operatively. In adults, a great increase in operative treatment has been reported. We aimed to analyze the respective trend and potential explanatory factors in children. METHODS: This is a single-institution retrospective study in a subregion in Northern Finland. The ICD-code S42.0 was used to identify the cases in the hospital registry. Altogether, 214 children, aged < 16, with consecutive clavicle fractures were first enrolled in the area during 2008-2019. Hospital journals and radiographs were reviewed. After lateral and medial fractures and patients living outside the area were excluded, final study population was 172. The respective population at risk was extracted by Statistics Finland. Predictive factors and annual rates of operative treatment as adjusted for 100,000 children at risk were determined. RESULTS: The rate of the surgical treatment of clavicle fractures increased from zero in 2008 to 10.8 in 2019 per 100,000 age-adjusted children (ß = 0.864, 95% confidential intervals (CI) 0.4 to 1.4). There was a rise in the rate of surgery from 2.6% (2014-16) to 16.1% (2017-19) (diff. 13.5, 95% CI 1.7 to 23.3%). A displacement > 15 mm and a shortening of > 15 mm were associated with the increased risk of surgery but did not change during the study period. Age > 9 years increased the risk of surgery; the mean age increased from 5.5 years (2008-10) to 8.5 years (2017-19). There was a 3.6-fold increase in sports-related fractures (95% CI 7.4 to 26.4). The severity of the fractures did not change. CONCLUSIONS: There has been an increasing trend in the surgical fixation of pediatric middle shaft clavicle fractures since 2008. The available literature does not support the trend.

Surgical fixation of metastatic spine fractures: 6-months experience at a cancer hospital from a developing country - an audit.

OBJECTIVE: To audit the outcomes in cases of surgical fixation for metastatic spine fractures at a single centre. METHODS: The retrospective audit was conducted at the Surgical Oncology Department of the Shaukat Khanum Memorial Cancer Hospital, Lahore, Pakistan, and comprised data of all patients who underwent surgery for metastatic spine fractures from December 1, 2019, to May 31, 2020. The patients were followed up for three months after the surgery. Pre-surgery American Spinal Injury Association Impairment Scale grades were compared with post-operative grades for all the patients. Data was analysed using SPSS 20. RESULTS: Of the 16 patients, 12(75%) were females and 4(25%) were males, with an overall mean age of 44.0±11.9 years (range: 24-64 years). The only co-morbid was hypertension, which was present in 6(37.5%) patients. The most common primary site was breast 10(62.5%), and 12(75%) patients presented more than 12 months after the initial diagnosis. Lumbar spine was involved in 10(62.5%) cases. Pre-operative American Spinal Injury Association Impairment Scale grade was E in 8(50%) patients. Post-operatively, 14(87.5%) patients had the E grade. There was complication in 1(6.25%) case that had a post-operative wound infection. CONCLUSIONS: Surgery for spinal metastases was found to be a safe and viable option for patients with metastatic spine fractures in resource-limited countries like Pakistan.

Multimodal imaging of composite carbon fiber-based implants for orthopedic spinal fixation.

OBJECTIVE: As cancer treatments continue to improve, the incidence of spinal metastases and the need for surgical management of these with fixation procedures are growing rapidly. Traditionally metallic implants, composed of titanium alloy, have been used in surgical fixation of unstable or symptomatic vertebral metastases or traumatic injuries. Metallic implants, however, cause significant artifact on post-operative imaging, degrading image quality and limiting interpretation, and can also impair the planning and delivery of radiotherapy. Composite carbon fiber-based materials, such as carbon fiber-reinforced polyetheretherketone (PEEK), have been developed to overcome these issues and are now available for spinal fixation procedures. We aimed to review the multimodal imaging features of these new implants. MATERIALS AND METHODS: Current literature and a case example from our institution were used to describe the multimodal imaging characteristics and considerations of new carbon fiber-based spinal fixation implants. RESULTS: New carbon fiber-based spinal implants allow far greater visualization of surrounding structures on post-operative cross-sectional imaging, significantly improving diagnostic accuracy and precision of radiotherapy planning, and do not significantly absorb or scatter X-ray photons during radiotherapy delivery. There are, however, important surgical and radiologic considerations associated with the use of carbon fiber-based implants which radiologists must be aware of, such as implications for surgical planning and intra-operative fluoroscopic and post-operative plain radiographic imaging. CONCLUSION: The use of carbon fiber-based implants, rather than traditional metallic implants, for spinal fixation offers significant advantages for post-operative diagnostic imaging and radiotherapy planning and delivery.

Distal Radius Fracture Clinical Practice Guidelines-Updates and Clinical Implications.

The American Academy of Orthopaedic Surgeons and the American Society for Surgery of the Hand released updated Clinical Practice Guidelines in 2020 on the evaluation and treatment of acute distal radius fractures. Following a rigorous methodology designed and implemented through the AAOS, 7 guidelines based upon the best available evidence were released to assist surgeons and physicians managing distal radius fractures. These guidelines can serve as a reference for surgeons when managing patients with distal radius fractures. We review the evidence behind each guideline and highlight the practical implications of each guideline on care.

Radiological and clinical features of traumatic atlanto-occipital dislocation.

PURPOSE: We aimed to describe the findings of traumatic atlanto-occipital dislocation (AOD) on cervical spine CTs and differences leading to varying treatment of these patients. METHODS: We retrospectively identified 20 adult patients with AOD from cervical spine CTs demonstrating fracture or fracture dislocations over 19 years at 2 major trauma centers. Medical records were reviewed and craniovertebral junction (CVJ) metrics measured on CT. Intubation, Glasgow Coma Scale (GCS), additional injuries, occiput/atlas/axis fracture, concurrent atlantoaxial subluxation, vascular injury on CT angiography, and ligamentous injury on MRI were noted. RESULTS: Using the Traynelis Classification, eight patients had type 2 and eight patients type 3 AOD. Four of 5 patients who died within 14 days of CT had type 2 AOD. Three patients had medial/lateral AOD. Of the patients who survived initial injuries, a greater percentage who underwent surgical or halo fixation versus non-operatively treated patients had abnormal CVJ measurements including BDI (62.5% vs 0%), atlantoaxial subluxation (75% vs 14.3%), ligamentous injury (80% vs 66.7%), intubation (62.5% vs 28.6%), GCS<8 (62.5% vs 14.3%), and additional injuries (75% vs 71.4%) on presentation. MRI helped identify 2 cases of type 2 AOD and surgical decision making in 8 cases. CONCLUSIONS: Types 2 and 3 were the most common, and type 2 is the deadliest type of AOD. A greater proportion of patients who undergo surgical or halo fixation have abnormal CT/MR findings with neurologic impairment at presentation. MRI aided detection of potentially missed type 2 AOD and was critical for surgical decision making.

Diagnostic Accuracy of e-FAST in Stable Blunt Trauma Chest: A Prospective Analysis of 110 Cases at a Tertiary Care Center.

BACKGROUND: Focused assessment with sonography in trauma (FAST) is an important adjunct and an extension of the clinical examination in an emergency setting for the last three decades. e-FAST visualizes the lung bases and injuries related to the lungs in addition to the intra-abdominal and pericardial bleed. In trauma patients, time is precious. Noncontrast computed tomography (NCCT) chest is the gold standard for the evaluation of blunt trauma chest. However, it is cumbersome and time-consuming and leads to increased morbidity and mortality. Therefore, evaluation of trauma patients at the trauma bay with e-FAST which is available at all times will not only save time but also the lives of trauma patients. Our endeavor is to find whether e-FAST can be substituted for NCCT for assessing injuries accurately in a stable blunt trauma patient. PATIENT AND METHODS: Prospective observational study was conducted in a tertiary care trauma center during the period of November 2017 to 2019. Of the 197 patients presenting to the trauma surgeon in the trauma center, 110 were included in the study after satisfying the inclusion criteria. Eighty-seven patients being hemodynamically unstable were excluded from the study. RESULTS: There was no statistical significance in the comparative data between the groups and all with "p" values more than 0.05. This accepts the null hypothesis and establishes the fact that there is no difference between NCCT chest which is the gold standard for chest blunt trauma and e-FAST. CONCLUSION: We conclude that e-FAST is a better adjunct to the diagnosis and management of blunt trauma chest patients.

Return to work after surgically treated acetabular fractures in an Asian population.

BACKGROUND: Acetabular fractures are rare but are severe injuries that occur in younger patients with a significant economic impact. There is limited evidence describing the return to work rates in this group of patients. The aim of our study was to examine the rate and time to return to work (RTW) after surgical fixation of acetabular fractures. METHODS: We performed a retrospective study on all patients with surgically treated acetabular fractures at a single institution between 1 July 2010 and 31 December 2018. Medical records were reviewed to analyze demographics such as age, gender, occupation and RTW characteristics. RESULTS: There were 30 patients, with a mean age of 43.3 ± 12.7 years. There were 26 patients who were employed prior to injury. The most common mechanism of injury was from a road traffic accident (73.3%). The average ISS was 8.9 ± 5.2. The mean follow-up duration was 21.5 months ± 15.7. The rate of RTW was 80.8%. Eighteen patients (85.7%) returned to the same job and duties, while two (9.5%) returned with same job but lighter duties and one (4.8%) had to change job. Three patients (11.5%) retired. The average time to return to work was 8.3 months (range 2-57.5). RTW rates were 15.4%, 61.5%, 69.2% at 3, 6 and 12 months, respectively. CONCLUSION: Acetabular fractures can lead to loss of economic productivity, with 80.8% of patients returning to work. Work reintegration programs after acetabular fractures are important.

Clinical and radiological mid- to long-term results after direct fixation of posterior malleolar fractures through a posterolateral approach.

BACKGROUND: Direct fixation of posterior malleolar fractures has been shown to lead to higher accuracy of fracture reduction compared to an indirect anterior to posterior fixation but lacks long-term clinical results. This study shows the mid- to long-term clinical and radiological outcome after direct fixation of the posterior malleolus through a posterolateral approach. MATERIALS AND METHODS: Thirty-six patients with an ankle fracture including a posterior malleolar fragment (23 × AO-44C, 12 × AO-44B, 1 × unclassifiable) treated with direct fixation of the fragment through a posterolateral approach were retrospectively evaluated. There were 24 females (67%) with a mean age of 63 (range 34-80) years and a BMI of 28 (range 19-41) kg/m2 at the time of surgery. An initial fracture-dislocation was seen in 67%. The clinical outcome was assessed with the Visual Analog Scale (VAS, 0-10 points) and the American Foot and Ankle Society (AOFAS, 0-100 points) score. Posttraumatic osteoarthritis was recorded with the Van Dijk Classification (grade 0-III). Subgroup analyses of patient- and fracture-associated risk factors (age, BMI, smoking, fracture-dislocation, postoperative articular step-off) were assessed to reveal possible negative prognostic predictors. RESULTS: After a mean follow-up of 7.9 (range 3-12) years, the median VAS was 1 (IQR 0-2) point, and the median AOFAS score was 96 (IQR 88-100) points. Ankle range of motion measurements showed a significant, but clinically irrelevant, difference in plantar- and dorsiflexion between the affected and unaffected ankle. 92% of the patients were very satisfied or satisfied with the postoperative course. 89% had no preoperative signs of ankle osteoarthritis. Osteoarthritis progression was seen in 72%, with 50% showing grade II or III osteoarthritis at the final follow-up. No significant negative prognostic factors for a worse clinical outcome could be detected. CONCLUSION: Direct fixation of posterior malleolar fractures through a posterolateral approach showed good clinical mid- to long-term results with a high satisfaction rate but substantial development of posttraumatic ankle osteoarthritis. Further studies should include CT analysis of the preoperative fracture morphology and even, perhaps, the postoperative reduction accuracy to evaluate the benefit of posterior malleolar fracture reduction in preventing ankle osteoarthritis in the long term. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for authors for a complete description of levels of evidence.

Hook Plate Fixation of Medial Malleolar Fractures: A Comparative Study of Clinical Outcomes.

Medial malleolar fractures, occurring in isolation or in bi- or trimalleolar fractures, require surgical fixation if there is any displacement. Several techniques have been described in the literature for open reduction and internal fixation of medial malleolar fractures, but no data exist on the functional outcomes after fixation with a hook plate. The objective of this review study was to compare complication and union rates in patients who underwent hook plate fixation of medial malleolar fractures to those who underwent fixation with 2 lag screws. A total of 31 patients were included in the study. They were all followed for a minimum of 6 months from the day of surgery. There was a 18% to 35% complication rate with this technique; however, there was no statistical difference in the complication rate between medial malleolar fracture fixation with hook plate versus 2 lag screws in our study. All patients in this study went on to have a successful union. Hook plate fixation is an acceptable alternative to medial malleolar fracture fixation, especially in patients at high risk for poor bone healing.

Os acromiale open reduction and internal fixation: a review of iliac crest autogenous bone grafting and local bone grafting.

BACKGROUND: Symptomatic os acromiale are fairly uncommon, and treatment has included fragment excision, decompression, and open reduction and internal fixation. Nonunion rates as high as 40% have been reported after fixation of os acromiale. This study assessed whether union of an os acromiale could be reliably achieved without the use of an iliac crest bone graft. METHODS: This was a retrospective study of 32 consecutive shoulders that were treated with screw fixation and a local bone graft or iliac crest bone graft. The mean age was 50.3 years (range, 21-74 years), and the mean follow-up was 46.9 months (range, 12-120 months). Fusion was assessed clinically and radiologically. RESULTS: All 32 os acromiale were fused by 3 months on x-ray imaging. There were 18 shoulders in the iliac crest bone graft group and 14 in the local bone graft group. Rotator cuff repairs were performed concomitantly in 25 patients. Hardware was removed in 4 patients, a seroma was drained in 1 patient, and a superficial infection occurred in 1 patient. CONCLUSION: This is the largest study of os acromiale fixation using screws and a tension band to our knowledge. We report a 100% union rate using this technique, with 13% requiring hardware removal and the occurrence of 1 superficial infection. This study shows a local bone graft is as effective as iliac crest bone graft in achieving fusion.
