Optimizing Outcomes after Operative Treatment Bicondylar Tibial Plateau Fractures - Time for Innovation?

Bicondylar tibial plateau fractures are technically demanding fractures that have a high complication rate. We sought to review the recent literature with the aim to summarize the development of new classification systems that may enhance the surgeon's understanding of the fracture pattern and injury. We highlight the best methods for infection control and touch on new innovative solutions using 3D printer models and augmented mixed reality to provide potentially personalized solutions for each specific fracture configuration.

Do Long-Segment Blocking Screws Increase the Stability of Intramedullary Nail Fixation in Proximal Tibia Fractures, Eliminating the "Bell-Clapper Effect?"

OBJECTIVES: To determine change in stiffness and horizontal translation of a geriatric extra-articular proximal tibia fracture model after intramedullary nailing with distal (long)-segment blocking screws versus proximal (short)-segment blocking screws. METHODS: Unstable extra-articular proximal tibia fractures (OTA/AO 41-A3) were created in 12 geriatric cadaveric tibias. Intramedullary nails were locked with a standard construct (4 proximal screws and 2 distal screws). Specimens were then divided into 2 groups (6 matched pairs per group). Group 1 had a blocking screw placed lateral to the nail in the proximal segment (short segment). Group 2 had a blocking screw placed 1 cm distal to the fracture and medial to the nail (long segment). Specimens were then axially loaded and cycled to failure or cycle completion (50,000 cycles). RESULTS: Long-segment blocking screws significantly decreased the amount of horizontal translation at the fracture site compared with short-segment screws (0.77 vs. 2.0 mm, P = 0.039). They also resulted in a greater trend towards greater baseline stiffness, (807.32 ± 216.95 N/mm vs. 583.12 ± 130.1 N/mm, P = 0.072). There was no difference in stiffness after cyclic loading or survival through 50,000 cycles between the long-segment and short-segment groups. CONCLUSION: Long-segment blocking screws added to an intramedullary nail construct resulted in decreased horizontal translation at the fracture site compared with short-segment screws in this model of a geriatric proximal tibia fracture. CLINICAL RELEVANCE: Blocking screws are commonly used to aid in fracture alignment during intramedullary nailing of proximal tibia fractures. Even when not required to attain or maintain alignment, the addition of a blocking screw in either the proximal or the distal (long) segment may help mitigate the "Bell-Clapper Effect" in geriatric patients.

OrthoPass: Long-term Outcomes following Implementation of an Orthopaedic Patient Handoff Template.

Standardized handoff tools improve communication and patient care; however, their widespread use in surgical fields is lacking. OrthoPass, an orthopaedic adaptation of I-PASS, was developed in 2019 to address handoff concerns and demonstrated sustained improvements across multiple handoff domains over an 18-month period. We sought to characterize the longitudinal effect and sustainability of OrthoPass within a single large residency program 3.5 years after its implementation. This mixed methods study involved electronic handoff review for quality domains in addition to survey distribution and evaluation. We conducted comparative analyses of handoff adherence and survey questions as well as a thematic analysis of provider-free responses. We evaluated 146 electronic handoffs orthopaedic residents, fellows, and advanced practice providers 3.5 years after OrthoPass implementation. Compared with 18-month levels, adherence was sustained across five of nine handoff domains and was markedly improved in two domains. Furthermore, provider valuations of OrthoPass improved regarding promoting communication and patient safety (83% versus 70%) and avoiding patient errors and near misses (72% versus 60%). These improvements were further substantiated by positive trends in Agency for Healthcare Research and Quality Surveys on Patient Safety Culture hospital survey data. Thematic analysis of free responses shared by 37 providers (42%) generated favorable, unfavorable, and balanced themes further contextualized by subthemes. At 3.5 years after its introduction, OrthoPass continues to improve patient handoff quality and to support provider notions of patient safety. Although providers acknowledged the benefits of this electronic handoff tool, they also shared unique insights into several drawbacks. This feedback will inform ongoing efforts to improve OrthoPass.

Impact of Age on Functional Outcome After Reverse Shoulder Arthroplasty Performed for Proximal Humerus Fractures or Their Sequelae.

Background: The use of reverse shoulder arthroplasty (RSA) to treat displaced, unstable 3- and 4-part proximal humerus fractures (PHFs) has traditionally been reserved for patients over 70 years old. However, recent data suggest that nearly one-third of all patients treated with RSA for PHF are between 55-69 years old. The purpose of this study was to compare outcomes for patients younger than 70 versus patients older than 70 years of age treated with RSA for a PHF or fracture sequelae. Methods: All patients who underwent primary RSA for acute PHF or fracture sequelae (nonunion, malunion) between 2004 and 2016 were identified. A retrospective cohort study was performed comparing outcomes for patients younger than 70 versus older than 70. Bivariate and survival analyses were performed to evaluate for survival complications, functional outcomes, and implant survival differences. Results: A total of 115 patients were identified, including 39 patients in the young group and 76 cases in the older group. In addition, 40 patients (43.5%) returned functional outcomes surveys at an average of 5.51 years (average age range: 3.04-11.0 years). There were no significant differences in complications, reoperation, implant survival, range of motion, DASH (27.9 vs 23.8, P=0.46), PROMIS (43.3 vs 43.6, P=0.93), or EQ5D (0.75 vs 0.80, P=0.36) scores between the two age cohorts. Conclusion: At a minimum of 3 years after RSA for a complex PHF or fracture sequelae, we found no significant difference in complications, reoperation rates, or functional outcomes between younger patients with an average age of 64 years and older patients with an average age of 78 years. To our knowledge, this is the first study to specifically examine the impact of age on outcome after RSA for the treatment of a proximal humerus fracture. These findings indicate that functional outcomes are acceptable to patients younger than 70 in the short term, but more studies are needed. Patients should be counseled that the long-term durability of RSA performed for fractures in young, active patients remains unknown.

High- Versus Low-Energy Intertrochanteric Hip Fractures in Young Patients: Injury Characteristics and Factors Associated With Complications.

OBJECTIVE: To compare fracture patterns and associated injuries for young patients with high- versus low-energy intertrochanteric hip fractures and to report on factors associated with complications after surgical fixation of high-energy fractures. DESIGN: Retrospective comparative study. SETTING: Academic Level 1 Trauma Center. PATIENTS: A total of 103 patients 50 years of age or younger were included: 80 high-energy fractures and 23 low-energy fractures. INTERVENTION: Cephalomedullary nailing (N = 92) or a sliding hip screw (N = 11). MAIN OUTCOME MEASURES: Radiographic characteristics of fracture morphology, implant position, and reduction quality and postoperative complications were the main outcome measures. RESULTS: Compared with young patients with low-energy fractures, those with high-energy fractures had more fracture comminution ( P = 0.013) and higher ISS scores ( P < 0.003) and were more likely to require open reduction ( P < 0.001). Patients with low-energy fractures from a ground-level fall had higher rates of alcohol abuse (0.032), cirrhosis (0.010), and chronic steroid use (0.048). Overall reoperation rate for high-energy fractures was 7%, including 2 IT fracture nonunions (5%) and 1 deep infection (2%). For high-energy fractures, ASA class ( P = 0.026), anterior lag screw position ( P = 0.001), and varus malreduction ( P < 0.001) were associated with malunion. Four-part fracture (OTA/AO 31A2.3/Jensen 5) ( P = 0.028) and residual calcar gap >3 mm ( P = 0.03) were associated with reoperation. CONCLUSIONS: Surgical treatment of high-energy IT fractures in young patients is technically demanding with potential untoward outcomes. Injury characteristics and severity are significantly different for young patients with high-energy IT fractures compared with low-energy fractures. For young patients with a high-energy IT fracture, surgeons can anticipate a high rate of associated injuries and complex fracture patterns requiring open reduction. For young patients with a low-energy IT fracture, comanagement with a hospitalist or a geriatrician should be considered because they may be physiologically older.

Complications and timing of soft tissue coverage after complete articular, open tibial plateau fractures.

PURPOSE: Complete articular tibial plateau fractures are typically high-energy injuries associated with significant soft tissue trauma. The primary aim of this study was to evaluate the incidence of wound complications and need for soft tissue coverage after open, complete articular tibial plateau fractures. The secondary aim was to study the effect of timing of fixation and timing of flap coverage on deep infection rates in these injuries. METHODS: This was a retrospective cohort study of consecutive patients > 18 years undergoing ORIF of a Bicondylar Tibial Plateau (BTP) fracture between 2001 and 2018. Surgical data were recorded for open fractures including number of debridements, timing of definitive ORIF and soft tissue coverage relative to injury. Primary outcomes included rates of deep infection and unplanned reoperation. RESULTS: 508 AO/OTA 41C BTP fractures were identified, with 51 open fractures included in 50 patients with a mean (SD) age 45.7 (12.3) years and a mean (SD) follow up of 4.3 (3.8) years. There were 20 cases of deep infection, unplanned reoperation occurred in 26 cases. The majority of cases (28 fractures) had initial external fixation placed, while 24 had ORIF at the initial debridement. Twelve patients had a planned flap for definitive closure on average of 6.4 days (SD 3.9) after injury, 14 required a flap for wound complications. Among patients with IIB and C injuries, rates of deep infection (5/6 vs 1/6, p = 0.02) and reoperation (5/7 vs 2/6, p = 0.08) were higher in patients treated with flap coverage >7 days from injury compared to early flap coverage. There were no differences in complication rates between early (<24hrs) and delayed fixation. CONCLUSIONS: Complete articular, open tibial plateau fractures are associated with high rates of complications. Time to flap coverage of seven days or more was a significant predictor of deep infection and unplanned reoperation in this cohort. Patients should be counseled about the high rate of unplanned reoperation and definitive soft tissue coverage should be accomplished within a week of injury whenever possible.

Does a Reduced Secondary Operation Rate Offset Higher Implant Charges when Utilizing Suture Button Fixation for Syndesmotic Injuries?

OBJECTIVE: To determine whether a reduced secondary operation rate offsets higher implant charges when using suture button fixation for syndesmotic injuries. DESIGN: Retrospective cohort study. SETTING: Single, urban, Level 1 trauma center. PARTICIPANTS: Three-hundred twenty-seven (N = 327) skeletally mature patients with rotational ankle fractures (OTA/AO type 44) necessitating concurrent syndesmotic fixation. INTERVENTION: Suture button or solid 3.5-mm screw syndesmotic fixation. MAIN OUTCOME MEASUREMENTS: To compare implant charges with secondary operation charges based on differential implant removal rates between screws and suture buttons. RESULTS: Patients undergoing screw fixation were older (48.8 vs. 39.6 years, P < 0.01), had more ground-level fall mechanisms (59.3% vs. 51.1%, P = 0.026), and sustained fewer 44C type injuries (34.7% vs. 56.8%, P = 0.01). Implant removal occurred at a higher rate in the screw fixation group (17.6% vs. 5.7%, P = 0.005). Binomial logistic regression identified nonsmoker status (B = 1.03, P = 0.04) and implant type (B = 1.41, P = 0.008) as factors associated with implant removal. Adjusting for age, the NNT with a suture button construct to prevent one implant removal operation was 9, with mean resulting additional implant charges of $9747 ($1083/case). Backward calculations using data from previous large studies estimated secondary operation charges at approximately $14220, suggesting a potential 31.5% cost savings for suture buttons when considering reduced secondary operation rates. CONCLUSIONS: A reduced secondary operation rate may offset increased implant charges for suture button syndesmotic fixation when considering institutional implant removal rates for operations occurring in tertiary care settings. Given these offsetting charges, surgeons should use the syndesmotic fixation strategy they deem most appropriate in their practice setting. LEVEL OF EVIDENCE: Economic Level IV.

Sustained Improvement in Quality of Patient Handoffs After Orthopaedic Surgery I-PASS Intervention.

PURPOSE: The I-PASS tool has been shown to decrease medical errors in patient handoffs in nonorthopaedic surgery fields. We prospectively studied the implementation of a version of this handoff tool modified for orthopaedic surgery patients in an academic practice at two level I trauma centers. METHODS: This was a prospective study of a multicenter handoff improvement program. Handoffs were evaluated preintervention and at 1, 6, 9, and 18 months postintervention for key data elements defined by I-PASS. Rates of adverse clinical outcomes were compared before and after the handoff intervention. RESULTS: Seven hundred five electronic patient handoffs were analyzed. From preintervention to the 18-month time point, notable improvement was observed in 8 of 9 targeted quality elements. In Poisson regression analysis, adherence to the standardized handoff format was sustained at markedly improved levels throughout all postintervention time points. No statistically significant differences were observed between rates of 30-day readmission, 90-day readmission, urinary tract infection, pulmonary embolism/deep vein thrombosis, surgical site infection, or delirium before and after the intervention. CONCLUSION: Introduction of an orthopaedic-specific I-PASS tool produced sustained adherence from a group of over 50 orthopaedic providers. Objective quality of handoffs improved markedly as defined by the I-PASS standard, and 86% of the providers supported the ongoing use of the tool. Despite the improvement in handoff quality, we were unable to demonstrate a notable change in measured clinical outcomes. Methods for the development and implementation of the orthopaedic-specific I-PASS tool are described. Orthopaedic residency programs should consider using a version of I-PASS to standardize care.

Single versus dual incision approaches for dual plating of bicondylar tibial plateau fractures have comparable rates of deep infection and revision surgery.

OBJECTIVES: The use of one midline incision versus dual medial/lateral incisions for dual plating of bicondylar tibial plateau (BTP) fractures is controversial. This study aimed to compare rates of infection and secondary surgery in patients treated with dual plating for a BTP fracture using a single versus double incisions. DESIGN: Retrospective cohort study. SETTING: Two Level-1 trauma centers. PATIENTS/PARTICIPANTS: Patients > 18 years with a closed AO/OTA 41-C BTP fracture without compartment syndrome treated with a single midline or dual incision (lateral with medial or posteromedial) approach for dual plating. INTERVENTION: Dual plating through either a single anterior incision, or dual medial/lateral incisions. MAIN OUTCOME MEASUREMENTS: Rates of deep infection and reoperation were compared using Chi-square analysis (p-value of < 0.05). RESULTS AND CONCLUSIONS: In total 636 AO/OTA 41-C BTP fractures treated between 1/1/01 and 12/31/18 were identified and assessed. After exclusions for limited follow up, other techniques, open fracture and the need for fasciotomies, 346 patients were studied. Of these 254 had been treated with a single plate / single approach technique while 92 had been dual plated, 41 through a single anterior incision while 51 had dual plating through separate lateral and medial or posteromedial incisions. For these 92 fractures, there was no significant difference in the rate of deep infection (22.0% vs 23.5%, s=0.858) or reoperation (31.7% vs 31.4%, p=0.973) between the single and dual incision groups. Injuries that had been treated with single plating via a single incision had comparably lower rates of deep infection (10.2% vs. 22.8%, p=0.003) and reoperation (12.2% vs. 31.5%, p<0.001). There were no significant differences in any demographic parameters between patients undergoing single versus dual plating. Although retrospective, not randomized and subject to single surgeon bias these data suggest that these complications are more based on injury than the approach. LEVEL OF EVIDENCE: III.

Outcomes after ORIF of Bicondylar Schatzker VI (AO type C) Tibial Plateau Fractures in an Elderly Population.

BACKGROUND: The surgical management of bicondylar tibial plateau (BTP) fractures in elderly patients aims to restore knee stability while minimizing soft tissue complications. The purpose of this study was to compare injury characteristics and surgical outcomes after ORIF of BTP fractures (AO/OTA 41-C (Schatzker VI)) in young (< 50 years) versus elderly (> 65 years) patients. METHODS: A retrospective cohort study was conducted using data from two American College of Surgeons (ACS) level I trauma centers. Inclusion criteria were: (1) age 18 years or older, (2) bicondylar tibial plateau fracture (AO/OTA 41-C or Schatzker VI), (3) treatment with ORIF, and (4) minimum of 6 months follow-up. Patients between 50 and 65 years of age were excluded. Data collection was performed by reviewing electronic medical records, operative reports, and radiology reports. RESULTS: We identified 323 patients (61% male) with 327 BTP fractures and a median follow-up of 685 days. There were 230 young patients (71%) < 50 years and 93 elderly patients (29%) >6 5 years at time of presentation. Elderly patients were significantly more likely to have a low energy mechanism of injury (44.6 vs. 16.2%, p < 0.001), and present with diabetes (19.4 vs. 4.4%, p < 0.001) or coronary artery disease (12.9 vs. 1.3%, p < 0.001). Elderly patients were also significantly less likely to undergo staged management with initial knee-spanning external fixation followed by delayed ORIF (19.2 vs. 33.9%, p = 0.008). Elderly patients had a lower arc of motion at final follow-up (105 vs. 113°, p < 0.001) and reduced PROMIS-10 function scores (43.8 vs. 49.8, p = 0.013). No differences were observed in rates of superficial infection, deep infection, reoperation, or EQ-5D scores between age groups. CONCLUSIONS: This is the largest study to compare injury characteristics and outcomes after ORIF of BTP fractures according to age. Elderly patients (age > 65 years) sustained BTP fractures by lower energy mechanisms than their younger counterparts with similar fracture patterns and were often managed with ORIF. The results of this study suggest that ORIF of BTP fractures in elderly patients is associated with similar complication rates and outcomes as in younger patients despite higher comorbidities and poorer bone quality in the elderly population.

Is It Safe to Prep the External Fixator In Situ During Staged ORIF of Bicondylar Tibial Plateau Fractures? A Retrospective Comparative Cohort Study.

OBJECTIVES: To compare the risk of deep infection and unplanned reoperation after staged open reduction internal fixation (ORIF) of bicondylar tibial plateau (BTP) fractures whether elements of the temporizing external fixator were prepped into the surgical field or completely removed before definitive fixation. DESIGN: Retrospective comparative cohort study. SETTING: Two academic Level 1 trauma centers. PATIENTS/PARTICIPANTS: One hundred forty-seven OTA/AO 41-C (Schatzker 6) BTP fractures treated with a 2-stage protocol of acute spanning ex-fix followed by definitive ORIF between 2001 and 2018. INTERVENTION: Seventy-eight fractures had retained elements of the original ex-fix prepped in situ during surgery for definitive internal fixation, and 69 had the ex-fix construct completely removed before prepping and draping. MAIN OUTCOME MEASURES: Deep infection and unplanned reoperation. RESULTS: Among 147 patients treated with staged ORIF, the overall deep infection rate was 26.5% and the reoperation rate was 33.3%. There were high rates of deep infection (26.9% vs. 26.1%, P = 0.909) and unplanned reoperation (30.8% vs. 36.2%, P = 0.483) in both groups, but no difference whether the ex-fix was prepped in or completely removed. Within the retained ex-fix group, there was no difference in infection with retention of the entire ex-fix compared with only the ex-fix pins (28.1% vs. 26.1%, P = 0.842). CONCLUSIONS: We observed high complication rates in this cohort of OTA/AO 41C BTP fractures treated with staged ORIF, but prepping in the ex-fix did not lead to a significant increase in rates of infection or reoperation. This study provides the treating surgeon with clinical data about a common practice used to facilitate definitive fixation of unstable BTP fractures. LEVEL OF EVIDENCE: Therapeutic Level III.

Anatomic Structures at Risk During Posterior to Anterior Percutaneous Screw Fixation of Posterior Malleolar Fractures: A Cadaveric Study.

Background. There are no established guidelines for fixation of posterior malleolus fractures (PMFs). However, fixation of PMFs appears to be increasing with growing evidence demonstrating benefits for stability, alignment, and early functional outcomes. The purpose of this study was to determine the risk to anatomic structures utilizing a percutaneous technique for posterior to anterior (PA) screw fixation of PMFs. Methods. Percutaneous PA screw placement was carried out on 10 fresh frozen cadaveric ankles followed by dissection to identify soft tissue and neurovascular structures at risk. The distance from the guidewire to each anatomic structure of interest was measured. The correlation between the mean distances from the guidewire to each structure was calculated. Results. The sural nerve was directly transected in 1/10 specimens (10%) and in contact with the wire in a second specimen (10%). There was a significant correlation between the proximity of the guidewire to the apex of Volkmann's tubercle and its proximity to the sural nerve. The flexor hallucis longus (FHL) muscle belly was perforated by the guidewire 40% of the time but was not tethered or entrapped by the screw. Conclusions. Percutaneous PA screw placement is a safe technique which can be improved with several modifications. A mini-open technique is recommended to protect the sural nerve. There may be potential for tethering of the FHL with use of a washer or large screw head. Risk to the anterior and posterior neurovascular bundles is minimal.Levels of Evidence: Level V.

Radiographic Outcomes and Complications of Delayed Fixation of Distal Radius Fractures.

BACKGROUND: Surgeons are sometimes presented with patients with distal radius fractures who present in a delayed fashion or lose reduction after several weeks of attempted closed management. There are limited studies on delayed surgical treatment of distal radius fractures to assist providers in decision-making. METHODS: We conducted a matched cohort study to compare radiographic outcomes and complications for patients with a distal radius fracture treated with delayed (3-5 weeks) or early (0-2 weeks) surgical fixation. Patients ages 18+ who underwent open reduction and internal fixation of distal radius fractures by a volar approach at 2 Level I trauma centers between 2003 and 2015 were eligible. We measured radiographic outcomes and reviewed medical records to determine operative approach and complications. RESULTS: There were 25 cases and 50 controls matched for age (18-87), sex, and AO fracture type. The delayed group had surgery at a mean of 24.8 days from injury and the early group at 5.6 days. There was no statistically significant difference between the delayed and early cohorts in radiographic parameters on injury x-rays, in improvement in radiographic parameters on first postoperative x-rays, or in maintenance of radiographic parameters at union. CONCLUSION: We did not find significant differences in radiographic outcomes or complication rates between patients with delayed versus early surgical treatment for distal radius fracture. Providers treating patients with late presentation or late displacement have the option of surgical fixation beyond the first few weeks after injury.

3-D generated anatomic custom talar cement spacers: case reports, technical tips and literature review.

BACKGROUND: With today's expanding use of total ankle arthroplasty, the ever-present trauma patient, and patients with uncontrolled comorbid conditions, surgeons face significant challenges for lower extremity reconstruction. These patients highlight some of those who may present with unique anatomy, bone loss, infection, and various other local and systemic factors that affect treatment options for successful outcomes. Three dimensional (3-D) printing for medical devices is allowing for new and customized ways to meet patient and surgeon goals of limb salvage and reconstruction. CASE PRESENTATIONS: While the majority of 3-D printing is done for the purpose of implantation, we present a technical tip for designing a 3-D printed mold from which to create an antibiotic cement spacer for implantation. With two case illustrations including a talus fracture nonunion and infected subtalar arthrodesis nonunion, we describe the process of patient selection, implant design, fabrication, and implantation of a custom molded antibiotic cement talus. DISCUSSION: Case illustrations present two successful limb salvage patients while giving a thorough explanation of our technique, learned tips and tricks. This applied technology builds on prior use of antibiotic cement in limb salvage of the lower extremity, most of which are joint sacrificing. 3-D printing the mold for an anatomic talus cement spacer results in a joint sparing limb salvage solution. Innovative 3-D printing technology is merged with current, pertinent literature regarding antibiotic cement to offer surgeons expanded options for temporary or definitive reconstructive techniques in some of the most challenging patients.

Correlation and responsiveness of global health, upper extremity-specific, and shoulder-specific functional outcome measures following reverse total shoulder arthroplasty for proximal humerus fracture.

PURPOSE: Reverse total shoulder arthroplasty (rTSA) is effective and increasingly utilized for the management of proximal humerus fracture (PHF). However, the optimal patient-reported outcome metrics (PROMs) for the evaluation of patient outcomes after this surgery are unclear. We investigated the correlation among global, upper extremity-specific, and shoulder-specific PROMs in patients undergoing rTSA for PHF as well as the responsiveness of these PROMs as assessed by floor and ceiling effects. We hypothesized that patients' post-operative outcome would be best reflected by a combination of these metrics. METHODS: Thirty patients with a history of rTSA for ipsilateral PHF filled out the following outcomes questionnaires at a minimum of 3 years post-op: EQ-5D, EQ-5D VAS, PROMIS physical function, DASH, SSV, SPADI, and ASES. Correlation between metrics was assessed using the Spearman correlation coefficient. Responsiveness was assessed by comparing the proportion of patients reaching floor or ceiling values using McNemar's test. RESULTS: Global health metrics (EQ-5D and PROMIS physical function) were strongly correlated with the upper extremity-specific metric (DASH). Shoulder-specific outcomes (SPADI, ASES, and ASES) were moderately correlated with both the global metrics and DASH. There was no significant difference between PROMs with regards to floor and ceiling effects. CONCLUSIONS: The DASH score has been shown to be valid and responsive for shoulder interventions, and our data demonstrate that it correlates strongly with overall quality of life. Shoulder-specific metrics are valid and responsive for shoulder interventions but correlate less with global quality of life. An optimal PROM strategy in rTSA for PHF might involve both DASH and a shoulder-specific score. Based on our assessment of floor and ceiling effects, none of these metrics should be excluded for poor responsiveness.

Acute versus delayed reverse total shoulder Arthroplasty for the management of Proximal Humerus Fractures.

OBJECTIVES: Proximal humerus fractures (PHF) are common, yet their optimal management remains debated. Reverse total shoulder arthroplasty (rTSA) is an increasingly popular option, particularly for non-reconstructible or osteoporotic fractures. Despite this trend, current literature provides limited guidance with regards to surgical timing and patient selection for rTSA. A trial of non-operative management might be beneficial for many patients who are not clearly indicated for surgery, provided this does not have a major negative impact on results for those who ultimately require rTSA. The purpose of this study was to investigate whether delayed reverse shoulder arthroplasty for fracture (>28 days from injury) is associated with any difference in complication rates or functional outcomes relative to acute surgery. DESIGN: Retrospective cohort study PATIENTS/PARTICIPANTS: 114 consecutive patients who underwent rTSA as the primary management of a PHF at two Level 1 trauma centers and one academic community hospital between 2004 and 2016. INTERVENTION: rTSA as primary management of proximal humerus fracture MAIN OUTCOME MEASUREMENTS: Complications, range of motion, and patient-reported functional outcomes scores (DASH, PROMIS physical function, and EQ-5D) RESULTS: Eighty-two of 114 patients (72%) underwent early surgery. Complex (4-part, head-split, dislocated) fractures were significantly more common in the acutely treated group. There was no significant difference in complications. Overall complication rate was 11.4%. There was a significant difference in DASH score favoring early surgery, with an average score of 22.4 in acutely treated patients versus 35.1 in delayed patients (p = 0.034). There was a non-statistically significant trend towards better PROMIS physical function scores and ROM in the acutely treated group. CONCLUSION: Delay in performing primary rTSA for management of PHF does not lead to an increase in complication rates but it may come at the cost of worse functional outcomes in patients who ultimately require rTSA.

Anterior Syndesmotic Augmentation Technique Using Nonabsorbable Suture-Tape for Acute and Chronic Syndesmotic Instability.

Syndesmotic instability is a source of significant pain and disability. Both subtle instability and gross diastasis, whether acute or chronic, require stabilization and may benefit from reconstruction with ligamentous augmentation. The use of nonabsorbable suture-tape has emerged as a promising operative strategy, allowing surgeons to anatomically reconstruct the syndesmosis, in particular the anterior inferior tibiofibular ligament. The current work provides a detailed description of the technique and preliminary results of a patient cohort treated using nonabsorbable suture-tape for syndesmotic augmentation.Level of Evidence: Level V, expert opinion.

Acute and Chronic Syndesmotic Instability: Role of Surgical Stabilization.

Acute and chronic syndesmotic injuries significantly impact athletic function and activities of daily living. Patient history, examination, and judicious use of imaging modalities aid diagnosis. Surgical management should be used when frank diastasis, instability, and/or chronic pain and disability ensue. Screw and suture-button fixation remain the mainstay of treatment of acute injuries, but novel syndesmotic reconstruction techniques hold promise for treatment of acute and chronic injuries, especially for athletes. This article focuses on anatomy, mechanisms of injury, diagnosis, and surgical reduction and stabilization of acute and chronic syndesmotic instability. Fixation methods with a focus on considerations for athletes are discussed.

Surgical Treatment of Acute Periprosthetic Knee Infection with Concurrent Presumed COVID-19: A Case Report.

CASE: We report the case of a 64-year-old man who presented with a late onset of acute periprosthetic joint infection after total knee arthroplasty and a positive severe acute respiratory syndrome coronavirus 2 polymerase chain reaction test. We describe our perioperative protocol and challenges for ensuring the safety of healthcare providers while operating on a coronavirus disease 2019 (COVID-19)-positive patient. CONCLUSIONS: Given the incredible spread of COVID-19 globally, hospitals should anticipate perioperative protocols for the surgical management of COVID-19-positive patients with concurrent pathology to ensure safety to healthcare providers.

Getting the Starting Point Right: Prevention of Skiving and Fibular Cortical Breach During Suture Button Placement for Syndesmotic Ankle Injuries.

The use of suture button (SB) devices in the treatment of syndesmotic ankle injuries is increasing. These constructs have demonstrated better syndesmotic reduction, improved clinical outcomes, and lower rates of hardware removal compared with screw fixation. However, placing a SB device without a fibular plate can be technically challenging. In this technique tip, we use an illustrative case to demonstrate a technique tip that minimizes the risk of anterior or posterior cortical breach of the fibula and helps facilitate more accurate placement of a SB device.Levels of Evidence: Level V: Expert opinion.
