Opioid use patterns and risk characteristics among injured patients.

Background: Injured patients are at risk for prolonged opioid use after discharge from care. Limited evidence exists regarding how continued opioid use may be related to opioid medication misuse and opioid use disorder (OUD) following injury. This pilot study characterized opioid consumption patterns, health characteristics, and substance use among patients with active prescriptions for opioid medications following injury care. Methods: This study was a cross-sectional screening survey combined with medical record review from February 2017 to March 2018 conducted among outpatient trauma and orthopedic surgery clinic patients. Eligible patients were 18-64 years of age, admitted/discharged for an injury or trauma-related orthopedic surgery, returning for clinic follow-up ≤6 months post hospital discharge after the index injury, prescribed opioid pain medication at discharge, and currently taking an opioid medication (from discharge or a separate prescription post discharge). Data collected included demographic, substance use, mental health, and physical health information. Descriptive and univariate statistics were calculated to characterize the population and opioid-related risks. Results: Seventy-one participants completed the survey (92% response). Most individuals (≥75%) who screened positive for misuse or OUD reported no nonmedical/illicit opioid use in the year before the index injury. A positive depression screen was associated with a 3.88 times increased likelihood for misuse or OUD (95% confidence interval [CI] = 1.1-13.5). Nonopioid illicit drug use (odds ratio [OR] = 1.89, 95% CI = 1.1-3.4) and opioid craving (OR = 1.29, 95% CI = 1.1-1.5) were also associated with increased likelihood for misuse or OUD. Number of emergency department visits in the 3 years previous to the index injury was associated with a 22% likelihood of being misuse or OUD positive (95% CI = 1.0-1.5). Conclusions: Patients with behavioral health concerns and greater emergency department utilization may have heightened risk for experiencing adverse opioid-related outcomes. Future research must further establish these findings and possibly develop protocols to identify patients at risk prior to pain management planning.

Late reconstruction of severe open-book deformities of the pelvis - tips and tricks.

BACKGROUND: The primary goal of treatment for open book pelvic injuries after high-energy trauma is to control haemorrhage and to close the pelvic ring anatomically. Less commonly, patients may present late with malunion or non-union. METHODS: We reviewed five operatively treated patients with delayed severe open book deformities who had a diastasis of more than 6 cm. We describe the pre-operative workup, surgical strategy and challenges experienced. They specifically include: extensive scar and contracture formation, malunion, urogenital prolapse and difficult reduction of vertical shear element. A 5 to 15-point clinical scoring system based on quality of life regarding pain, ambulation, social function, continence control and presence of prolapse is proposed. RESULTS: One elderly patient had early mortality after surgery. The other four patients had quality of life improvement by 3 to 5 points after one year. Correction is often clinically successful despite technical challenges and unpredictable radiological results. CONCLUSION: External fixator and the C-clamp are good reduction tools. Powerful implants should be used and fixation of the posterior ring is mandatory. Staged urogenital and pelvic floor reconstruction is recommended before bony reconstruction to minimize the risk of wound contamination. Patients receiving this complex procedure have a good chance for improvement in pain and functional status.

Treatment of periprosthetic femur fractures around a well-fixed hip arthroplasty implant: span the whole bone.

INTRODUCTION: Periprosthetic femur fractures are a growing problem in the geriatric population. This study examines Vancouver B1 periprosthetic femur fractures treated with open reduction internal fixation using a laterally based plate. Outcomes using plates which spanned the length of the femur to the level of the femoral condyles were compared to those which did not. The hypothesis was that spanning internal fixation would result in a decreased rate of refracture and subsequent reoperation. MATERIALS AND METHODS: Patients admitted to three affiliated academic hospitals treated with open reduction internal fixation for a periprosthetic femur fracture in the setting of a preexisting total hip arthroplasty or hemiarthroplasty stem were identified. Patient data were reviewed for age, gender, fracture classification, operative intervention, time to union, as well as complications related to treatment and need for further surgery. RESULTS: Over a 5-year period, 58 patients were treated with open reduction internal fixation using a laterally based plate for Vancouver B1 femur fractures. Twenty-one patients were treated with plates that extended to the level of the femoral condyles. In that group there were no nonunions or subsequent periprosthetic fractures reported. Of 36 patients treated with short plates, 3 went on to nonunion resulting in plate failure and refracture and 2 sustained a subsequent fracture distal to the existing fixation. CONCLUSIONS: In this series, fixation for periprosthetic femur fractures around a well-fixed arthroplasty stem which spans the length of the femur to the level of the femoral condyles is associated with a decreased rate of nonunion and refracture. By decreasing the rate of refracture and nonunion, spanning fixation decreases the morbidity and mortality associated with additional surgery in a fragile geriatric population.

Unstable intertrochanteric femur fractures: is there a consensus on definition and treatment in Germany?

BACKGROUND: Extramedullary and intramedullary implants have improved in recent years, although consensus is lacking concerning the definition and classification of unstable intertrochanteric fractures, with uncertainties regarding treatment. QUESTIONS/PURPOSES: We conducted a national survey of practicing chairpersons of German institutions to determine current perspectives and perceptions of practice in the diagnosis, management, and surgical treatment of unstable intertrochanteric fractures. METHODS: Between January and February 2010, we emailed 575 German chairpersons of trauma and/or orthopaedic departments, asking them to complete a 26-question web-based survey regarding three broad domains: fracture classification and instability criteria, implants and surgical treatment algorithms, and timing of operations. Response rate was 42%. RESULTS: There was a clear preference for use of the AO/OTA fracture classification with geographic variations. Absence of medial support was considered the main criterion for fracture instability (84%), whereas a broken lateral wall and detached greater trochanter were considered by 4% and 5% of the respondents, respectively, to determine instability. Two percent routinely fixed unstable intertrochanteric fractures with extramedullary devices. Ninety-eight percent of German hospitals reportedly perform surgery within 24 hours after admission. Time to surgery was dependent on hospital level, with more direct surgeries in Level I hospitals. CONCLUSIONS: Despite varying opinions in the literature in recent years, we found some instability criteria (lateral wall breach, a detached greater trochanter) played a minor role in defining an unstable intertrochanteric fracture pattern. Despite recent meta-analyses suggesting clinical equivalence of intra- and extramedullary implants, few respondents routinely treat unstable intertrochanteric fractures with extramedullary plates. Additional studies are required to specify the influence of fracture characteristics on complication rate and function and to establish a classification system with clear treatment recommendations for unstable intertrochanteric fractures.

Primary versus secondary distal femoral arthroplasty for treatment of total knee arthroplasty periprosthetic femur fractures.

Current methods of fixing periprosthetic fractures after total knee arthroplasty (TKA) are variable, and include open reduction and internal fixation (ORIF) via plating, retrograde nailing, or revision using standard revision TKA components or a distal femoral arthroplasty (DFA). The purpose of this study is to compare patients who failed plating techniques requiring subsequent revision to DFA to patients who underwent primary DFA. Of the 13 patients (9.2%) who failed primary ORIF, causes included nonunion (53.8%), infection (30.8%), loosening (7.7%), and refracture (7.7%). There were significantly more surgical procedures for ORIF revision to DFA compared to primary DFA. Complications for patients who underwent primary reconstruction with DFAs included extensor mechanism disruption (8.3%), infection (5.6%), and dislocation (2.8%). Primary reconstruction via ORIF is beneficial for preserving bone stock, but primary DFA may be preferred in osteopenic patients, or those at high risk for nonunion.

Management of High-Energy Tibial Pilon Fractures.

➤ Pilon fractures in the younger patient population are frequently high-energy, intra-articular injuries and are associated with devastating, long-term impacts on patient-reported outcomes and health-related quality of life, as well as high rates of persistent disability.➤ Judicious management of associated soft-tissue injury, including open fractures, is essential to minimizing complications. Optimizing medical comorbidities and negative social behaviors (e.g., smoking) should be addressed perioperatively.➤ Delayed internal fixation with interval temporizing external fixation represents the preferred technique for managing most high-energy pilon fractures presenting with characteristically substantial soft-tissue trauma. In some cases, surgeons elect to utilize circular fixation for these scenarios.➤ Although there have been treatment advances, the results have been generally poor, with high rates of posttraumatic arthritis, despite expert care.➤ Primary arthrodesis may be indicated in cases with severe articular cartilage injury that, in the opinion of the treating surgeon, is likely unsalvageable at the time of the index management.➤ The addition of intrawound vancomycin powder at the time of definitive fixation represents a low-cost prophylactic measure that appears to be effective in reducing gram-positive deep surgical site infections.

Temporizing Care of Acute Traumatic Foot and Ankle Injuries.

Temporizing care has become a critical part of the treatment armamentarium for select foot and ankle injuries. Indications for performing temporizing care are based on the specific injury pattern, the host, associated injuries, as well as surgeon resources. Foot and ankle injuries are often associated with severe adjacent injury to the soft tissue sleeve. An acute procedure performed through a traumatized soft tissue envelope will often lead to the failure of wound healing and/or infectious complications. Thus, delayed reconstruction of acute foot and ankle injuries is often advisable in these cases.

Male sex, Gustillo-Anderson type III open fracture and definitive external fixation are risk factors for a return to the or following the surgical management of geriatric low energy open ankle fractures.

INTRODUCTION: Open ankle fractures in geriatric (age > 60 years) patients are a source of significant morbidity and mortality. Surgical management includes plate and screw fixation (ORIF), retrograde hindfoot nail (HFN), definitive external fixation (ex-fix) and below knee amputation. However, each modality poses unique challenges for this population. We sought to identify predictors of unplanned OR and short-term mortality after geriatric open ankle fractures managed by our service. MATERIALS AND METHODS: In an IRB-approved protocol, we evaluated patients over 60 years of age managed for a low energy open ankle/distal tibia pilon fracture by trauma fellowship-trained surgeons from a single academic department that covers two level I trauma centers. Our primary outcome was an unplanned return to the OR. Secondary outcomes were a 90-day "event", defined as an all-cause hospital readmission or mortality, and 1-year mortality. Differences with a p-value < 0.1 measured on univariate analysis were evaluated using a multivariable logistic regression to identify independent outcome predictors. RESULTS: A total of 113 (60 ORIF, 36 HFN, 11 ex-fix, 6 amputations) were performed. Cohort mean age was 75.2 ± 9.8 years, and 31 patients (27.4%) were male. Mean age-adjusted charlson comorbidity index was 5.5 ± 2.0. Significant independent predictors of an unplanned return to the OR were male sex (OR 4.4, 95% CI 1.3 to 15.4), Gustilo Type III open fracture (OR 4.9, 95% CI 1.5 to 17.5) and ex-fix (OR 15.6, 95% CI 2.7 to 126.3). Independent predictors of a 90-day "event" were walker/minimal ambulation (OR 3.5, 95% CI 1.3 to 10.4), surgical site infection (OR 4.8, 95% CI 1.8 to 13.8) and reduced BMI (OR 0.9, 95% CI 0.9 - 0.99), while independent predictors of 1-year mortality were age (OR 1.1, 95% CI 1.003 to 1.2), ACCI (OR 1.4, 95% CI 1.02 to 2.0) and walker/minimal ambulator (OR 7.5, 95% CI 1.7 to 53) CONCLUSIONS: Host factors, particularly pre-operative mobility, were most predictive of 90-day event and 1-year mortality. Only definitive external fixation was found to influence patient morbidity as a significant predictor of unplanned OR. However, no surgical modality had any influence on short-term readmission or survival.

Postoperative radial nerve palsy in humeral shaft nonunion reconstruction: Can the lateral paratricipital approach prevent this common complication?

BACKGROUND: Postoperative radial nerve palsy (RNP) is a well-known complication of nonunion reconstruction of the humerus. The purpose of the current study is to determine if the surgical approach for nonunion reconstruction of the humerus influences the rate of postoperative radial nerve palsy. METHODS: A retrospective case-control study of all humeral shaft and extraarticular distal humerus nonunion reconstructions performed between January 1, 2004, and August 31, 2021, was conducted. Patients included were over 18 years of age, had a non-pathologic humerus fracture nonunion and had intact radial nerve function prior to nonunion reconstruction. Exclusion criteria consisted of nonunions involving the proximal humerus, intraarticular fractures, and reconstructive treatment procedures with either intramedullary nail or external fixation methods. Perioperative variables were recorded and analyzed in regard to the development of postoperative RNP. A subgroup analysis was performed to assess the interaction of significant variables on the development of postoperative RNP. RESULTS: The overall rate of postoperative RNP in this series was 6/53 (11%). However, no cases of postoperative radial nerve palsy were observed in patients who underwent nonunion reconstruction with a lateral paratricipital approach. A new RNP was seen in 4/9 (44%) of those patients who underwent a triceps splitting approach, which was significantly higher than those utilizing either an anterolateral approach (2/28, 7%) or a lateral paratricipital approach (0/16, 0%, p = 0.007). DISCUSSION AND CONCLUSION: Our data suggests that the lateral paratricipital exposure decreases the risk of radial nerve injury with nonunion reconstruction of the humerus. The lateral paratricipital exposure offers the benefit of radial nerve exploration, decompression, neurolysis and protection prior to fracture manipulation and instrumentation. This study shows conventional approaches may predispose patients to a high rate of postoperative RNP, similar to that in the literature.

Effects of pelvic volume changes on retroperitoneal and intra-abdominal pressure in the injured pelvic ring: a cadaveric model.

BACKGROUND: Pelvic ring injuries can be associated with severe blood loss and hemodynamic instability. The increase in pelvic volume in disrupted pelvic ring injuries is thought to cause accumulation of large volumes of blood in the retroperitoneal cavity. Extra abdominal compression for reduction of the pelvic ring may affect intrapelvic pressure. We examined the effects of pelvic volume changes on retroperitoneal pressures (RPP) and intra-abdominal pressures (IAPs) in the intact and unstable pelvic ring. METHODS: In a cadaver study, unembalmed human torsos were used. Infusion lines were placed adjacent to the sacroiliac joint in the retroperitoneum and in the abdominal cavity. IAP and RPP measurements were performed with sequential infusion of crystalloid solution in 1,000 mL increments. Measurements were performed in the intact pelvic ring and after induction of unilateral and bilateral instability by disruption of the pubic symphysis, the sacroiliac joints, the sacrotuberous ligaments, and sacrospinous ligaments. RESULTS: After infusion of 4,000 mL of saline, we observed a pressure increase in the retroperitoneal cavity (RPP) of 19.64 mm Hg ± 6.43 mm Hg in the intact pelvis, 5.22 mm Hg ± 1.74 mm Hg in unilateral instability, and 2.78 mm Hg ± 0.57 mm Hg in bilateral instability. The RPP response in the case of instability decreased significantly (p = 0.019). The IAP showed a change of 4.63 mm Hg ± 2.64 mm Hg in the intact pelvis, 3.88 mm Hg ± 1.84 mm Hg in unilateral instability, and 2.30 mm Hg ± 0.36 mm Hg in bilateral instability. Further infusion revealed a close association between RAPs and IAPs. CONCLUSIONS: In the intact pelvis, RPP rises rapidly with increasing volume. The results seem to support the idea that disrupted pelvic ring fractures may lead to a significant volume uptake that is reversed during reduction.

Subcuticular Barbed Suture and Skin Glue Wound Closure Decreases Reoperation and Length of Stay in Geriatric Hip Fractures When Compared With Staples.

INTRODUCTION: Patients with geriatric hip fracture are notoriously frail and at risk for complications. Persistent postoperative wound drainage can lead to prolonged hospital stay, increased risk for infection, and need for revision surgery. The purpose of this study was to determine the effect of wound closure technique, barbed monofilament subcuticular suture and skin glue versus staples on rates of intervention for wound drainage and length of hospital stay after geriatric hip fracture fixation. METHODS: A retrospective review of isolated hip fractures in patients older than 60 years at a single institution over a 3-year period was done. Hip fractures included femoral neck, intertrochanteric, and subtrochanteric femur fractures treated with internal fixation or arthroplasty. Skin closure technique, at the discretion of the operating surgeon, included either barbed subcuticular monofilament suture and skin glue or staples. Charts and radiographs were reviewed to determine patient characteristics, Charlson Comorbidity Index, type of wound closure, length of stay, and interventions for persistent wound drainage. RESULTS: There were 175 patients in the barbed suture and skin glue group and 211 patients in the staples group. The barbed suture group had an average postsurgical length of stay of 5.0 days which was significantly lower than the staples group (7.0 days, P < 0.00001). In the staples group, 17 patients (8%) required incisional negative pressure wound therapy due to wound drainage with five patients (2.4%) returning to the operating room secondary to persistent wound drainage. No patients were observed in the barbed suture group that required intervention for wound drainage. DISCUSSION: Barbed suture and skin glue closure is associated with markedly shorter hospital stay and fewer interventions for wound drainage when compared with staples after surgical treatment of geriatric hip fractures.

Is Obesity Associated With an Increased Risk of Complications After Surgical Management of Acetabulum and Pelvis Fractures? A Systematic Review.

BACKGROUND: When considering surgical fixation of acetabulum and pelvis fractures in patients with obesity, a thorough understanding of the risks of potential complications is important. We performed a systematic review to evaluate whether obesity is associated with an increased risk of complications after surgical management of acetabulum and pelvis fractures. METHODS: We searched PubMed/MEDLINE, EMBASE, and the Cochrane Library for studies published through December 2020 that reported the effect of increased body mass index (BMI) or obesity on the risk of complications after surgical treatment of acetabulum and pelvis fractures. RESULTS: Fifteen studies were included. Eight of the 11 studies that included infection or wound complication as end points found that increased BMI or some degree of obesity was a significant risk factor for these complications. Two studies found that obesity was significantly associated with loss of reduction. Other complications that were assessed in a few studies each included venous thromboembolism, nerve palsy, heterotopic ossification, general systemic complications, and revision surgery, but obesity was not clearly associated with those outcomes. CONCLUSIONS: Obesity (or elevated BMI) was associated with an increased risk of complications-infection being the most commonly reported-after surgical management of acetabulum and pelvis fractures, which suggests the need for increased perioperative vigilance.

Distal locking of short cephalomedullary nails decreases varus collapse in unstable intertrochanteric fractures - a biomechanical analysis.

INTRODUCTION: Peritrochanteric fractures are a growing problem and complications relating to operative fixation of these fracture, including varus collapse and screw cutout, are common in elderly osteoporotic patients. We hypothesize that unlocked nails will demonstrate increased varus collapse and inferior construct stiffness in specimens with increased diaphyseal medullary diameter. MATERIALS AND METHODS: Sixteen non-cadaveric osteoporotic biomechanical femur specimens were utilized in this study, with eight specimens having an artificially large femoral canal to represent Dorr C femurs. All femurs were instrumented with a short cephalomedullary nail with and without distal cross-lock screw fixation and had an unstable intertrochanteric fracture created in a repeatable pattern. Specimens underwent cyclic compression to a maximal load of 1000N with segmental motion quantified through the use of visual tracking markers. Statistical comparisons were performed using one-way ANOVA with Tukey post-hoc analysis to determine differences between specific groups. Significance was defined as p<0.05. RESULTS: Unlocked short cephalomedullary nails showed increased varus collapse due to motion of the nail within the femoral canal in capacious femoral canals compared with narrow femoral canals and distally cross-locked nails. The coronal deformation of the wide canal unlocked group (17.9 o±2.6o) was significantly greater in the varus direction than any other fixation under compressive load of 1000N. There was no significant difference in varus angulation between the wide canal or narrow canal locked groups (11.1o±8.7o vs. 8.2o±1.7o respectively, p=0.267). The narrow canal unlocked group (13.7o±2.4o) showed significantly greater varus angulation than the narrow canal locked (p=0.015). The wide canal unlocked group showed significantly greater varus angulation than the wide canal locked group (p=0.003). Motion between the femoral shaft and the cephalomedullary nail (toggling of the nail within the shaft) was significantly greater in narrow or wide canal unlocked specimens, 7.94o±2.13o and 10.2o±1.7o respectively, than in the narrow or wide canal locked specimens, 2.4o±0.2o and 4.2o±0.5o respectively (p<0.05) CONCLUSION: Unlocked short intramedullary fixation for unstable peritrochanteric fractures results in increased varus collapse under axial compression. This study supports the use of distal cross-locking of short intramedullary fixation for unstable peritrochanteric fractures in patients with capacious femoral canals secondary to osteoporosis who might otherwise be as risk for varus collapse, device failure, and malunion.

Increased Medial Displacement of the Humeral Shaft of at Least 40% Correlates With an Increased Incidence of Nerve Injury in Proximal Humerus Fractures.

BACKGROUND: Peripheral nerve and infraclavicular brachial plexus injury following proximal humerus fractures are commonplace, but diagnosing a concomitant nerve injury in the acute setting is challenging. Fracture displacement has been identified as a qualitative risk factor for nerve injury, and additional attention should be paid to the neurologic exams of patients with proximal humerus fractures with significant medial shaft displacement. However, a quantitative relationship between the risk of nerve injury and medialization of the humeral shaft has not been shown, and additional risk factors for this complication have not been assessed. The aim of this study was to identify the risk factors for a neurologic deficit following a proximal humerus fracture, with particular interest in the utility of the magnitude of medial shaft displacement as a predictor of neurologic dysfunction. METHODS: A retrospective chart review was performed on all proximal humerus fractures in a 3-year period (2012-2015) at a level one trauma center. Isolated greater tuberosity fractures (OTA 11-A1) were excluded. Fracture displacement was measured on initial injury AP shoulder radiograph and expressed as a percentage of humeral diaphyseal width. All orthopedic inpatient documentation was assessed to identify clinical neurologic deficits. RESULTS: We identified 139 patients for inclusion. There were 22 patients (16%) with new neurologic deficits at presentation (8 axillary nerve, 2 radial nerve, 12 infraclavicular brachial plexus or multiple nerve injuries). The average shaft medial displacement in patients with neurologic injuries was 59% vs. 21% without nerve deficits (p=0.03). Using a 40% medial displacement threshold, the odds ratio for a nerve injury was 5.24 (95% CI 1.54 - 17.77, p=.008). CONCLUSION: Increased medial displacement of the humeral shaft following proximal humerus fracture is associated with an increased incidence of nerve injury at the time of initial presentation. This finding is not meant to be a surrogate for a high-quality neurologic exam in all patients with proximal humerus fractures. However, improved knowledge of the specific risk factors for an occult neurologic injury will improve the clinician's ability to accurately diagnose and properly treat proximal humerus fractures and their sequelae.Level of Evidence: III.

Temporizing External Fixation vs Splinting Following Ankle Fracture Dislocation.

BACKGROUND: Closed reduction and splinting followed by outpatient management is standard of care for temporizing most ankle fractures. However, ankle fracture-dislocation potentially warrants a different approach based on the propensity for loss of reduction. The purpose of this study was to determine the rate of complications associated with closed reduction and splinting of unstable ankle fracture-dislocations. Further, we sought to determine the efficacy of immediate external fixation as an alternative to splinting in cases too swollen for acute operation. METHODS: This retrospective chart review analyzed all ankle-fracture dislocations that came through a large health care system from 2008 to 2018. Patients managed with acute open reduction internal fixation (ORIF) and open fractures were excluded. In patients managed late, the cohorts were divided into those temporized with closed reduction/splinting vs external fixation. Reduction quality and splint technique were additionally assessed in splinted patients. A total of 354 closed ankle fracture-dislocations were identified: 298 patients (84%) underwent ORIF within 48 hours and were excluded; 28 (15 female/13 male, average age 46.8 years) were placed in an external fixator and 28 (22 female/6 male, average age 57.2 years) were reduced, splinted, and discharged. RESULTS: At follow-up, 14 of the patients (50%) in the splint group developed loss of reduction and 5 of these patients (17.6%) developed anteromedial skin necrosis from skin tenting. None of the patients in the ex-fix group developed loss of reduction or skin necrosis. The rate of redislocation and the rate of development of skin necrosis was statistically higher in cases temporized with a splint versus an external fixator (P < .01 and P = .05, respectively). CONCLUSION: We found that in ankle fracture-dislocations not treated with acute ORIF, splint immobilization was associated with an increased risk of complications, including redislocation and skin necrosis, when compared to a temporizing external fixator. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Case report: The prone reduction of a sacroiliac disruption with a pelvic C-clamp.

The pelvic C-clamp traditionally is reserved for the temporizing stabilization of posterior ring injuries and reportedly has assisted in closed reduction of sacroiliac diastases, for patients who are in the supine position. We report a patient with a severely displaced Zone II sacral fracture and associated acetabular fracture who initially underwent fixation of the acetabulum in the prone position. By using the pelvic C-clamp as a tool for successfully reducing the sacrum, definitive closed fixation of the pelvic wing subsequently was performed without having to reposition the patient. In this case report, we review the literature on this device and for alternative reduction maneuvers for disrupted sacral injuries. The C-clamp may be a useful adjunct in select cases to facilitate closed reduction of sacral or sacroiliac joint disruptions, as may particularly apply in cases of severe displacement or when a reduction is hampered by obesity.

Early complications following the operative treatment of pilon fractures with and without diabetes.

BACKGROUND: An increased rate of complications has been clearly shown in diabetic patients undergoing operative treatment for displaced ankle fractures. To date, no studies have specifically looked at the complication rates following the operative management of pilon fractures in this difficult patient population. We performed a retrospective review to determine the rates of complications in diabetic patients undergoing operative fixation of tibial pilon fractures compared with a control group of patients without diabetes. MATERIALS AND METHODS: The trauma registry was utilized to identify all patients who underwent primary treatment for a tibial pilon fracture between January 2005 and June of 2007 at a single Level 1 trauma center. A minimum of 6-month followup was required for inclusion. A chart and radiographic review was completed to identify the complications seen in each patient population. Specifically, we looked at the rate of infection (superficial and deep), the rate of nonunion or delayed union, and the rate of surgical wound complications. RESULTS: A total of 14 fractures in 13 diabetic patients, and 69 fractures in 68 non-diabetic patients met inclusion criteria. In the diabetic patient group, the average age was 48 years, the average BMI was 35, and 36% of the fractures were open. In the non-diabetic group, the average age was 47 years, the average BMI was 29, and 35% of the fractures were open. Only the difference in BMI was statistically significant. The infection rate was 71% for diabetic patients (43% deep infection), and 19% for non-diabetic patients (9% deep infection) [p < 0.001, odds ratio 10.719 (95% confidence interval 2.914 to 39.798)]. Overall, the rate of non-union/delayed union was 43% in the diabetic group versus 16% in the non-diabetic group [p = 0.02, odds ratio 3.955 (95% confidence interval 1.145 to 13.656)]. The rate of surgical wound complications was 7% in both the non-diabetic and diabetic patient groups. CONCLUSION: The management of tibial pilon fractures in diabetic patients is difficult, with a high rate of complications compared to non-diabetic patients. These results mirror those previously reported for ankle fractures in diabetic patients.

Complete Bilateral Brachial Plexus Injury from Rhabdomyolysis and Compartment Syndrome: Surgical Case Report.

BACKGROUND AND IMPORTANCE: Acute bilateral brachial plexus injury is rare and usually a result of traction injury. Immediate operative intervention is reserved for rare cases of ongoing compression of the plexus; the role for acute decompression of the brachial plexus secondary to compartment syndrome has not been previously described. In this report, we describe the technique and role for urgent brachial plexus decompression. CLINICAL PRESENTATION: A 32-yr-old man presented with acute complete bilateral brachial plexus palsy due to focal rhabdomyolysis and brachial plexus compression after a night of excess alcohol and methadone ingestion. He had complete loss of motor and sensory function from C5 to T1, with the exception of partial sensory sparing of the C5 dermatome. Magnetic resonance imaging demonstrated diffuse muscular edema of the supraclavicular and infraclavicular fossae in addition to the pectoralis muscles and the deltoids bilaterally. He underwent urgent surgical decompression of his supraclavicular and infraclavicular fossae with fasciotomies of the pectoral muscles and the anterior deltoids, allowing direct visualization and decompression of the entire brachial plexus resulting in a near-complete functional recovery. CONCLUSION: Neurosurgeons should include brachial plexus compression due to compartment syndrome in the differential diagnosis of patients with acute upper extremity weakness, particularly when associated with prolonged immobilization and/or substance abuse. Prompt surgical decompression should be performed in these patients if imaging and laboratory data suggest compartment syndrome and resultant neurological deficit.

Reverse Total Shoulder Arthroplasty for Geriatric Proximal Humerus Fracture Dislocation With Concomitant Nerve Injury.

INTRODUCTION: Preoperative axillary nerve palsy is a contraindication to reverse total shoulder arthroplasty (rTSA) due to the theoretical risk of higher dislocation rates and poor functional outcomes. Treatment of fracture-dislocations of the proximal humerus with rTSA is particularly challenging, as these injuries commonly present with concomitant neurologic and soft tissue injury. The aim of the current study was to determine the efficacy of rTSA for this fracture pattern in geriatric patients presenting with occult or profound neurologic injury. METHODS: A retrospective case series of all shoulder arthroplasty procedures for proximal humerus fractures from February 2006 to February 2018 was performed. Inclusion criteria were patients aged greater than 65 years at the time of surgery, fracture-dislocations of the proximal humerus, and treatment with rTSA. Patients with preoperative nerve injuries were compared to patients without overt neurologic dysfunction. Forward elevation, Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH), Visual Analog Scale (VAS), and Subjective Shoulder Value (SSV) were obtained at final follow-up. RESULTS: Forty-six rTSA for acute fracture were performed during the study period, 16 patients met the inclusion criteria and 5 (31%) presented with overt preoperative nerve injuries. At mean 3.1 years follow up, there were no postoperative complications including dislocations and final forward elevation was similar between study groups. Patients with overt nerve palsy had higher QuickDASH and VAS scores with lower SSV and self-rated satisfaction. DISCUSSION: In the majority of patients with or without overt nerve injury, rTSA reliably restored overhead function and led to good or excellent patient-rated treatment outcomes. Overt nerve palsy did not lead to higher complication rates, including dislocation. Despite greater disability and less satisfaction, complete or partial nerve recovery can be expected in the majority of patients. CONCLUSION: Nerve injury following proximal humeral fracture dislocation may not be an absolute contraindication to rTSA.

Optimizing the Host in Fracture Surgery.

Multiple factors impact fracture healing; thus, endocrine optimization and nutritional optimization warrant investigation in the acute fracture and nonunion patient. This article presents current evidence regarding the role of the endocrinologists and the dietician in the fracture patient as well as the most recent data assessing the vitamin D axis in these populations. Similarly, the most recent information regarding the use and risks of NSAIDs in fracture healing are presented. The fracture surgeon must consider each individual patient and weigh the benefits versus the costs of host optimization.
