A Comparison of Wound Complications Following Total Hip Arthroplasty Performed Through the Direct Anterior Versus Direct Lateral Approach.

Background: Some studies have suggested the risk of wound complications may be higher using the direct anterior (DA) approach to total hip arthroplasty (THA). This study aimed to compare the risk of early postoperative wound complications between the DA and direct lateral (DL) approaches to THA and to determine patient risk factors that may contribute to this problem. Methods: All patients who underwent primary THA with a single surgeon over a 5-year period were retrospectively reviewed. All patients were treated with either the DA or DL approach. Data collected included patient demographics, surgical approach, and wound status. There was a minimum follow-up of 6 weeks to allow for an adequate assessment of surgical wound healing. Univariate and multivariate analyses were used to compare the 2 approaches. Results: Five hundred seventy-nine patients (77.6%) who underwent DA approach and 167 patients (22.4%) who underwent DL approach were included. Patients who underwent DL approach had a higher body mass index and a higher rate of diabetes than those treated with the DA approach. Forty patients (6.9%) in the DA cohort and 14 (8.4%) in the DL cohort experienced early wound complications, P = .523. After controlling for potential confounding variables, the surgical approach was not an independent risk factor for early postoperative wound complications. Conclusions: While there have been concerns regarding use of the DA approach in patients with higher body mass index and certain medical comorbidities, the results of this study suggest the choice of surgical approach may have minimal effect on the rate of early postoperative wound complications.

Talus Fractures: An Update on Current Concepts in Surgical Management.

Talus fractures can be challenging injuries to treat because of complex talar shape, an abundance of articular cartilage, a potentially unforgiving soft-tissue envelope, and an easily injured blood supply. In addition, the spectra of energy involved, soft-tissue injury, and the fracture pattern are wide. Temporizing treatment is sometimes required, including débridement of open fractures, reduction of dislocations, and occasionally spanning external fixation. Definitive treatment first requires an understanding of the fracture pattern, including location and fracture line orientation. Multiple options for surgical exposure exist and are selected based on the fracture pattern and condition of the soft tissues. Newer fixation techniques, including the use of fixed-angle and minifragment implants, are useful in achieving stable fixation.

Posteromedial Talar Body Fracture: Case Discussion and Surgical Technique.

SUMMARY: Posteromedial talar body fractures are a rare form of talus fracture that involves the tibiotalar and subtalar joints. In cases of displaced injuries, open reduction and internal fixation is typically recommended to minimize the risk of instability and post-traumatic osteoarthritis. This video presents a case of a posteromedial talar body fracture and highlights the technique for operative fixation through a posteromedial approach. Multiple methods to obtain reduction are discussed, and considerations with implant placement are described. The indications for surgical intervention are reviewed, and published outcomes following operative and nonoperative management of these injuries are presented.

Routine Indwelling Urinary Catheterization Is Not Necessary During Total Hip Arthroplasty Performed Under Spinal Anesthesia.

Background: Perioperative indwelling urinary catheterization remains common in patients undergoing total hip arthroplasty. This study sought to examine the effect of routine catheterization following total hip arthroplasty performed under spinal anesthesia on urinary complications. Methods: A total of 991 consecutive patients who underwent primary total hip arthroplasty under spinal anesthesia over a 4-year period were retrospectively reviewed. Major postoperative urinary retention (POUR) was defined as persistent retention following 2 straight catheterizations, which required postoperative indwelling catheter placement. Minor POUR was defined as retention that resolved following 1 or 2 straight catheterizations. Statistical analyses were used to compare outcomes between those who received a routine indwelling catheter and those who did not. Results: Of the 991 patients included, 498 (50.3%) underwent routine indwelling urinary catheter placement preoperatively. Routine indwelling catheterization was associated with a higher rate of urinary tract infection (1.4% vs 0.0%, P = .015), but a lower rate of minor POUR (5.0% vs 10.3%, P = .001). There was no difference with respect to the rate of major POUR or discharge with an indwelling catheter. Multivariate analyses demonstrated indwelling catheterization to be independently associated with a lower rate of minor POUR (P = .021), but there was no association with overall POUR, major POUR, or discharge with a urinary catheter. Conclusion: These data suggest that routine indwelling urinary catheterization is likely unnecessary for patients undergoing total hip arthroplasty in the setting of spinal anesthetic and may even lead to increased risk of complications such as urinary tract infection.

Autogenous iliac crest bone grafting for tibial nonunions revisited: does approach matter?

BACKGROUND: Tibial nonunion remains a considerable burden for patients and the surgeons who treat them. In recent years, alternatives to autogenous grafts for the treatment of tibial nonunions have been sought. The purpose of this study was to evaluate the efficacy of autogenous iliac crest bone graft (ICBG) in the treatment of tibial shaft nonunions. MATERIAL AND METHODS: Sixty-nine patients were identified who underwent ICBG for repair of atrophic or oligotrophic tibial nonunion and had complete data with at least one year of follow-up (mean 27.9 months). Surgical treatments consisted of revision/supplemental fixation ± ICBG. Surgical approaches for graft placement were either posterolateral (PL), anterolateral (AL), or direct medial (DM). Healing status, time to union, postoperative pain, and functional outcomes were assessed. RESULTS: Bony union was achieved by 97.1% (67/69) of patients at a mean time of 7.8 ± 3.2 months postoperatively. There was no significant difference in mean time to union between the three surgical approach groups: (PL (44.9%) = 7.3 months, AL (20.3%) = 9.2 months, DM (34.8%) = 7.6 months; p = 0.22). Intraoperative cultures obtained at the time of nonunion surgery were positive in 27.5% of patients (19/69). Positive cultures were associated with need for secondary surgery as 8/19 patients (42.1%) with positive cultures required re-operation. Two out of four patients that developed iliac donor site hematomas/infections requiring washout had positive intraoperative cultures as well. There was no difference in final SMFA among the three surgical approach groups. CONCLUSIONS: Autogenous ICBG remains the gold standard in the management of persistent tibial nonunions regardless of surgical approach. There is a small risk for complication at the iliac crest donor site. Given the high union rate, autogenous iliac crest bone grafting for tibial nonunion remains the gold standard for this difficult condition. LEVEL OF EVIDENCE: Level III.

Repair of proximal humerus fracture nonunions using a standardized treatment algorithm: a case series.

BACKGROUND: Nonunion of fractures about the proximal humerus represents a rare and complex problem. The purpose of this study was to evaluate the clinical and functional outcomes following proximal humerus fracture (PHF) nonunion repair using a plate and screw construct with a direct comparison to those experienced following operative fixation of acute PHF using a plate and screw construct. METHODS: Two separate patient cohorts were included in this study. The first consisted of 16 patients diagnosed with a non-united PHF who underwent operative nonunion repair treated with a standard algorithmic approach. The comparison group consisted of 173 patients who achieved union following initial open reduction and internal fixation of an acute PHF treated with a proximal humerus locking plate construct. All patients had at least 12 months of postoperative follow-up. Outcomes were assessed for both groups using American Shoulder and Elbow Surgeons (ASES) scores, visual analog scale (VAS) pain scores, and postoperative shoulder range of motion (ROM). Statistical analyses were used to compare these outcome measures between the two cohorts. RESULTS: The nonunion repair cohort consisted of eleven surgical neck nonunions and five nonunions of both the surgical neck and greater tuberosity. Ten patients had undergone surgical treatment for their original fracture, while six were initially treated non-operatively. All patients had Boileau type 3 sequelae of their proximal humerus fracture. Union was achieved in all patients at a mean of 5.4 months following nonunion repair. Complications included hardware failure requiring revision in two patients (12.5%) and avascular necrosis requiring conversion to anatomic total shoulder arthroplasty following union in one patient (6.3%). The nonunion repair and acute fracture cohorts did not differ with respect to mean ASES scores, VAS pain scores, or active shoulder ROM at any postoperative time point. CONCLUSION: Surgical repair of PHF nonunion is a viable treatment strategy that can lead to consistent bony healing with outcomes comparable to those of patients who achieve fracture union following initial surgical repair of an acute proximal humerus fracture. Surgeons should be cognizant of mechanical considerations that may lead to early failure.

The Impact of Subspecialty Fellows on Orthopaedic Resident Surgical Experience: A Multicenter Study of 51,111 Cases.

INTRODUCTION: Meaningful participation in surgery is important for orthopaedic resident education. This study aimed to quantify the effect of fellows on resident surgical experience. We hypothesized that as fellowship programs expanded, resident caseload would decrease, whereas "double-scrubbed" cases would increase. METHODS: This multicenter retrospective study included 9 years of surgical caselog data from two orthopaedic residency programs. Six subspecialty services on which fellow number varied over time were included (trauma, spine, foot and ankle, adult reconstruction, and hand). Case volume and personnel composition per case were extracted. Statistical analysis was performed with two-sample equal variance Student t-tests. RESULTS: A total of 51,111 cases were assessed. Surgical volume increased across all sites/services over time. Fellow numbers did not affect average resident caseload. However, in years with more fellows, an 11% decrease in one-on-one resident-attending cases (P = 0.002) and a 17% increase in resident-fellow-attending "double-scrubbed" cases was observed (P < 0.001). DISCUSSION: Increasing orthopaedic fellows did not affect resident case volume but resulted in fewer one-on-one cases with the attending and more "double-scrubbed" cases with a fellow. The implications of these findings to resident education require further study, but orthopaedic educators should be aware of these findings to try to maximize educational opportunities. LEVEL OF EVIDENCE: Level III.

Risk Factors for Elbow Joint Contracture After Surgical Repair of Traumatic Elbow Fracture.

PURPOSE: The ability to predict contracture development after elbow fracture would benefit patients and physicians. This study aimed to identify factors associated with the development of posttraumatic elbow joint contracture. METHODS: A retrospective review of elbow fractures (AO/Orthopaedic Trauma Association [OTA] type 13 and 21) treated at one institution between 2011 and 2015 was performed. Data collected included demographics, injury information, treatment, and postoperative elbow range of motion (ROM). Multivariate logistic regression analyses were performed to identify factors associated with contracture development. Notable contracture was defined as an arc of motion less than 100° flexion/extension, which has been associated with reduced ability to perform activities of daily living. RESULTS: A total of 278 patients at least 1 8 years of age underwent surgical repair of an elbow fracture or fracture-dislocation during the study period and had at least 6 months of postoperative follow-up. Forty-two (15.1%) developed a clinically notable elbow contracture, of whom 29 (69.0%) developed heterotopic ossification (HO). Multivariate analysis of preoperative variables demonstrated that AO/OTA 13-C fracture classification (odds ratio [OR], 13.7, P = 0.025), multiple noncontiguous fractures (OR, 3.7, P = 0.010), and ulnohumeral dislocation at the time of injury (OR, 4.9, P = 0.005) were independently associated with contracture development. At 6 weeks postoperatively, an arc of elbow ROM less than 50° flexion/extension (OR, 23.0, P < 0.0005) and the presence of HO on radiographs (OR, 6.7, P < 0.0005) were found to be independent risk factors for significant elbow stiffness. DISCUSSION: Ulnohumeral dislocation, multiple noncontiguous fractures, AO/OTA 13-C fracture classification, limited elbow ROM at 6 weeks postoperatively, and the presence of radiographic HO at 6 weeks postoperatively are associated with contracture development after surgical elbow fracture repair. Patients with these risk factors should receive aggressive physical therapy and be counseled as to the possible development of a contracture requiring surgical intervention.

Femoral Periprosthetic Fracture Nonunion Management and Outcomes with Nonunion Repair and Retention of Primary Components.

INTRODUCTION: Nonunion of a femoral periprosthetic fracture is a rare occurrence in orthopedic practice. Failure of a periprosthetic fracture to heal can lead to substantial disability and pain for patients as well as the potential need for component revision. Relatively little literature exists describing their management and outcome. METHODS: Eleven patients with femoral periprosthetic fracture nonunion who presented for tertiary care were enrolled in a prospective data registry. Patients were considered to have developed nonunion following failure of progression in radiographic and clinical healing for a 6-month period. All patients were seen at standard postoperative intervals, and outcomes were recorded using the Short Musculoskeletal Function Assessment (SMFA), visual analog scale (VAS) for pain, physical examination, and radiographic examination. Preoperative radiographs were reviewed for classification. RESULTS: Eleven patients had periprosthetic femoral fracture nonunion associated with prior hip (five patients) or knee (six patients) arthroplasty and were included in our study. Mean follow-up time was 30 months. Mean age at time of nonunion surgery was 64.5 years (range: 41.8 to 78.2 years). All patients underwent removal of previous fracture hardware at time of nonunion surgery. Ten (91%) of 11 received autogenous iliac crest bone grafting at time of nonunion surgery. Ten (91%) of the 11 patients went on to union without further intervention. Mean time to union was 7.9 months (SD: 8.0). The one patient that developed a persistent nonunion was complicated by infection requiring multiple irrigation and debridement procedures and total hip explant. The mean improvement in total SMFA score from baseline to final follow-up was 22.6 (p = 0.030). The greatest functional improvement was in the bothersome index at 28.0 (p = 0.028). The mean improvement in VAS pain score from baseline to final follow-up was 4.5 (p = 0.013). DISCUSSION: Periprosthetic fracture nonunions can be successfully treated with operative intervention aimed at compression plating with bone graft and retention of primary components. In addition, successful periprosthetic nonunion repair improves function and pain in these patients.

Predicting Functional Outcomes Following Fracture Nonunion Repair-Development and Validation of a Risk Profiling Tool.

OBJECTIVES: To develop a tool that can be used preoperatively to identify patients at risk of poor functional outcome following operative repair of fracture nonunion. DESIGN: Retrospective analysis of prospectively collected data. SETTING: Academic medical center. PATIENTS/PARTICIPANTS: Three hundred twenty-eight patients who underwent operative repair of a fracture nonunion were prospectively followed for a minimum of 12 months post-operatively. INTERVENTION: After randomization, 223 (68%) patients comprised an experimental cohort and 105 (32%) patients comprised a separate validation cohort. Within the experimental cohort, forward stepwise multivariate logistic regression was applied to 17 independent variables to generate a predictive model identifying patients at risk of having a poor functional outcome [Predicting Risk of Function in Trauma-Nonunion (PRoFiT-NU) Score]. MAIN OUTCOME MEASUREMENTS: Functional outcomes were assessed using the Short Musculoskeletal Function Assessment (SMFA). Poor outcome was defined as an SMFA function index greater than 10 points above the mean at 12 months post-operatively. RESULTS: Significant predictors of poor outcome were lower extremity nonunion [odds ratio (OR) = 3.082; P = 0.021], tobacco use (OR = 2.994; P = 0.009), worker's compensation insurance (OR = 3.986; P = 0.005), radiographic bone loss (OR = 2.397; P = 0.040), and preoperative SMFA function index (OR = 1.027; P = 0.001). The PRoFiT-NU model was significant and a good predictor of poor functional outcome (χ(5) = 51.98, P < 0.0005; area under the receiver operating curve = 0.79). Within the separate validation cohort, 16% of patients had a poor outcome at a PRoFiT-NU score below 25% (low risk), 39% of patients had a poor outcome at a PRoFiT-NU score between 25% and 50% (intermediate risk), and 63% of patients had a poor outcome at a PRoFiT-NU score above 50% (high risk). CONCLUSIONS: The PRoFiT-NU score is an accurate predictor of poor functional outcome following fracture nonunion repair. LEVEL OF EVIDENCE: Prognostic Level II.

Nonunited Lower Extremity Fractures Initially Repaired Outside the Developed Western World Develop a High Rate of Postoperative Complications After Nonunion Repair.

OBJECTIVES: To evaluate the clinical and functional outcomes after operative repair of nonunited lower extremity fractures initially repaired outside the developed Western world. DESIGN: Retrospective analysis of prospectively collected data. SETTING: Academic medical center. PATIENTS/PARTICIPANTS: From September 2004 through February 2017, 227 patients who underwent operative repair of a lower extremity fracture nonunion were prospectively enrolled in a research registry. All patients underwent previous fracture surgery and had at least 12 months of postoperative follow-up. INTERVENTION: Repair of lower extremity fracture nonunion. MAIN OUTCOME MEASUREMENTS: Postoperative complications, reoperation rate, time to union, and functional outcomes were assessed using the Short Musculoskeletal Function Assessment and Visual Analog Scale pain scores. Univariate and multivariate analyses were performed to evaluate the differences in patients who underwent initial fracture repair outside the developed Western world as opposed to within the United States. RESULTS: Twenty-one patients (9.3%) underwent initial fracture repair outside the developed Western world. These patients had a greater incidence of infected nonunions (47.6% vs. 23.3%; P = 0.015) and failure of a previous implant at the time of presentation (52.4% vs. 22.8%; P = 0.003) than those initially managed within the United States. This cohort also experienced a greater rate of postoperative complications after nonunion repair (23.8% vs. 6.3%; P = 0.016). The geographic location of initial fracture repair was not associated with postoperative Short Musculoskeletal Function Assessment scores or Visual Analog Scale pain scores after controlling for possible confounding variables. CONCLUSIONS: Patients who present with a nonunited lower extremity fracture initially repaired outside the developed Western world experience a high rate of postoperative complications after fracture nonunion repair but can expect good short- and long-term functional outcomes. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

This video describes a case of acute compartment syndrome of the arm. Relevant patient history, physical examination, and laboratory findings are discussed, and a presentation of the operative technique for arm fasciotomy through a lateral approach is highlighted. Diagnostic criteria for acute compartment syndrome and indications for fasciotomy are reviewed, with a discussion of published outcomes after fasciotomy.

Previous Implant Fractures: A New Descriptive Classification System.

OBJECTIVES: To propose a previous implant fractures (PIFs) classification system with good interobserver reliability. DESIGN: Retrospective classification. SETTING: Four academic medical centers. PATIENTS/PARTICIPANTS: A retrospective review of PIFs treated at 4 academic medical centers over 10 years was performed. Data collected included initial implant and PIF radiographs. There were 103 PIFs in 96 patients during the study period. Seventy-three (70.9%) were about plate/screw (PS) constructs and 30 (29.1%) were about intramedullary (IM) devices. INTERVENTION: Assignment of PIF classification. MAIN OUTCOME MEASUREMENTS: PIFs were classified based on initial implant (PS or IM) and fracture location with respect to the initial implant (proximal or distal to the implant, at the tip of the construct, or within the construct). Reliability of this scheme was assessed among 5 observers using Fleiss' kappa tests. RESULTS: Of PIFs about plate/screw constructs, 26.0% were proximal/distal to the implant (classification: PS1), 57.5% involved bone between the most proximal/distal screw and the same end of the plate (classification: PS2), and 16.4% involved only bone between the most proximal and distal screws (classification: PS3). Of PIFs about IM, 43.3% were distal to the device (classification: IM1), 46.7% involved bone between the most proximal/distal locking bolt and the same end of the device (classification: IM2), and 10.0% involved only bone between locking bolts (classification: IM3). Interobserver reliability for the classification system was excellent between observers, κ = 0.839, P < 0.0005. CONCLUSIONS: The proposed system offers a simple method to classify and describe fractures that occur about a previously implanted fracture device. Development of a classification system will allow for comparison of treatment modalities between injury types.

The use of regional anaesthesia for surgical intervention has minimal effect on functional outcomes following fracture nonunion repair.

PURPOSE: The purpose of this study was to determine the effect of regional anaesthesia as compared to general anaesthesia on clinical, functional, and radiographic outcomes following long bone fracture nonunion repair. METHODS: 262 patients who underwent operative repair of a long bone fracture nonunion and had at least 12 months of post-operative follow up were included in this study. Functional outcomes were assessed prospectively using the Short Musculoskeletal Function Assessment (SMFA) and Visual Analog Scale (VAS) pain scores prior to nonunion repair and at routine intervals post-operatively. Patients were divided into two matched groups based upon the type of anaesthetic method used in surgery. The regional anaesthesia cohort was composed of all patients who received regional anaesthesia (spinal anaesthesia or peripheral nerve block) alone or in addition to general anaesthesia, while patients who received general anaesthesia alone made up the general anaesthesia cohort. Univariate and multivariate analyses were performed to examine the effect of anaesthesia type on functional outcome scores, post-operative pain, bony healing, and complication rate. RESULTS: The regional anaesthesia and general anaesthesia cohorts each consisted of 131 patients. Multiple linear regression demonstrated there to be no significant association between anaesthetic method and total SMFA scores at all post-operative time points. Additionally, anaesthetic method was not associated with post-operative VAS pain scores, time to union, or the rate of post-operative complications. CONCLUSION: In this cohort, the use of regional anaesthesia during operative repair of long bone fracture nonunion was associated with no significant difference in functional outcome scores or pain levels at all post-operative time points. Furthermore, the use of regional anaesthesia had no effect on the rate of post-operative complications. Either type of anaesthetic appears to be safe and effective in performing these surgeries.

Autogenous Iliac Crest Bone Grafting for the Treatment of Fracture Nonunion Is Equally Effective in Elderly and Nonelderly Patients.

INTRODUCTION: Autogenous iliac crest bone graft (ICBG) is considered the benchmark graft for nonunion repair. However, ICBG harvest is invasive and may provide reduced benefit to elderly patients. The purpose of this study was to compare the clinical and functional outcomes of ICBG use in fixation of fracture nonunions between elderly and nonelderly patients. METHODS: Over a 13-year period, 242 patients who underwent operative repair of a long bone fracture nonunion and received autogenous ICBG were enrolled in a prospective research registry and followed. Data collected included patient demographics, injury information, and nonunion management. All patients had a minimum of 12 months of postoperative follow-up. Patients at least 65 years of age were classified as elderly, whereas younger patients were classified as nonelderly. Functional outcomes were evaluated at routine intervals postoperatively using the short musculoskeletal function assessment (SMFA) and visual analog scale pain scores. Bony union was determined radiographically. All postoperative complications were recorded. RESULTS: Of the 242 patients included, 44 were elderly and 198 were nonelderly. No differences were found between groups with respect to postoperative pain scores or SMFA scores. Furthermore, time to union, rate of union, and postoperative complication rate did not differ between groups. Multivariate linear regression demonstrated that older age was not associated with time to union, postoperative pain scores, or postoperative SMFA scores after controlling for possible confounding variables. DISCUSSION: The use of ICBG in nonunion repair among elderly patients is as effective as use in younger patients with a long bone nonunion. Concerns of increased postoperative complications and decreased rate of union in elderly patients receiving ICBG for treatment of fracture nonunion should be alleviated. ICBG remains the benchmark graft for nonunion repair among all age groups.

The association between patient education level and economic status on outcomes following surgical management of (fracture) non-union.

BACKGROUND: Socioeconomic disparities are an inherent and currently unavoidable aspect of medicine. Knowledge of these disparities is an essential component towards medical decision making, particularly among an increasingly diverse population. While healthcare disparities have been elucidated in a wide variety of orthopaedic conditions and management options, they have not been established among patients who present for treatment of an ununited fracture. The purpose of this study is to answer the following questions: 1) Following surgical management of (fracture) non-unions, are there differences in outcomes between differing ethnic groups? 2) Following surgical management of (fracture) non-unions, are there differences in outcomes between patients with differing education levels? 3) Following surgical management of (fracture) non-unions, are there differences in outcome between patients with differing incomes? METHODS: Between September 2004 and December 2017, operatively treated patients who presented with a long bone fracture non-union were prospectively followed. These patients presented with a variety of fracture non-unions that underwent surgical intervention. Sociodemographic factors were recorded at presentation. Long-term outcomes were evaluated using the Short Musculoskeletal Function Assessment (SMFA), pain scores, post-operative complications and physical exam at latest follow up. The SMFA is a 46-item questionnaire, assessing patient functional and emotional response to musculoskeletal ailments. RESULTS: Three-hundred-twenty-nine patients met inclusion criteria. Patients with a lower education had worse long-term functional outcomes (P < 0.001) and increased pain scores (P = 0.002) at latest follow-up. Patients who made less than $50,000 annually had worse long-term functional outcomes (P = 0.002) and reported higher pain scores (P = 0.003) following surgical management of (fracture) non-unions. Multiple linear regression demonstrated education level to be an independent predictor of long-term functional outcomes following surgical management of (fracture) non-unions (B= -0.154, 95% Confidence Interval [CI]=-10.96 to -1.26, P = 0.014). No differences existed in outcomes or pain scores between those of different ethnic groups. No differences existed regarding post-operative complications and time to union between patients of different ethnic groups, educational levels and income status. CONCLUSION: Patients with lower education levels and individuals who make less than $50,000 annually have worse functional outcomes following surgical management of (fracture) non-unions. Orthopaedic trauma surgeons should therefore be aware of these disparities, and consider early interventions aimed at optimizing patient recovery in these subsets.
