RESUMEN

INTRODUCTION: Open fractures in the elderly are distinct compared to younger populations. The purpose of this study is to follow a series of open fractures of the lower extremity in the geriatric population to better prognosticate outcomes. METHODS: We performed a retrospective chart review of patients over the age of 65 years old who were treated for an open, lower extremity fracture across two level I trauma medical systems. Patients were included if they had documented wound healing problems in the postoperative period, or 6 months of follow-up, or if they had a definitive radiographic outcome. Sixty-four patients were included of an average age of 76.23, of whom 73.4% were female. RESULTS: The fracture types were midshaft femur in 3, distal femur in 9, patella in 2, proximal tibia in 3, proximal fibula in 1, midshaft tibia in 14, distil tibia in 8, ankle in 23, and talar neck/calcaneus in 1. Forty-two fractures were the result of low energy mechanism and 22 fractures were from high energy mechanism. Fourteen fractures were type 1, 32 were type 2, 11 were type 3A, 6 were type 3B, and 1 was type 3C. At final follow-up, 13 wounds were well healed, 39 wounds were healed following a delay of more than 6 weeks to achieve healing, 3 were infected, 3 had been treated with amputation, 2 had chronic ulceration, 2 with active draining, and 2 had draining sinuses. DISCUSSION: Open lower extremity fractures are serious injuries with high rates of morbidity. Such risks are even higher in the geriatric population, particularly with regard to wound healing. This study provides important prognostic information in counseling geriatric patient with an open lower extremity fracture, as well as informs treatment in terms of wound surveillance and care in the postoperative period.

RESUMEN

Ankle fractures are increasingly common in elderly patients given the number of aging individuals who remain active. The already difficult aspects of ankle fixation are amplified by the compromised soft-tissue envelope and bone quality present in elderly patients with an ankle fracture. In addition, elderly patients with an ankle fracture often have compromised neuroprotective mechanisms and are physically unable to follow postoperative protected weight-bearing protocols during ambulation. Surgeons should be aware of strategies to improve fixation and maintain the tibiotalar relationship during ambulation in elderly patients with an ankle fracture.

RESUMEN

The effect of construct length on cortical strain and load to failure between locked compression plating and cemented femoral stem in a fall model was analyzed. Eight Sawbone femurs with cemented stems were instrumented with increasing fixation lengths starting 8cm distal to stem tip and progressing proximally to overlapping constructs. Uniaxial strain gauges measured cortical strain. Load to failure was performed with 8cm gap between implants, 2cm gap, and proximally overlapping configurations. Strain was significantly reduced as the 8cm gap transitioned to an overlapped construct with most comparisons. Load to failure in the overlapped construct was 273% greater compared to 2cm gap construct. Overlapping the stem with a locking compression plate resulted in reduced strain and increased load to failure.

RESUMEN

BACKGROUND: There is broad recognition that the healthcare crisis in the United States is going to require a response and change in clinical practice. The management structure of Geisinger Health System is unique, and this has the potential to change the dynamics of surgeon-administration alignment. QUESTIONS/PURPOSES: Our goal is to summarize and clarify the relationship between orthopaedic surgeons and the healthcare system at Geisinger, evaluate the positive and negative aspects, and consider which components may be reproducible. METHODS: This overview arises from a review of management publications, discussions with orthopaedic attendings and administrators, and personal observations and comparison with my previous 15-year university-based practice. RESULTS: The Geisinger Health System has always been physician-run. The overall efficiency and pragmatic approach found at Geisinger relies heavily on changing surgeon behavior to match what is optimal for the system rather than the individual. This approach appears to bring greater stability and more consistent outcomes, but only by removing what some see as the art of medicine and at the loss of perceived provider autonomy. Despite the rigid demands placed on the surgeon, the system remains adaptable to change and appears to retain faculty at a high rate. CONCLUSIONS: The Geisinger System is unique in its ability to control an insurance plan, multiple hospitals, and a large physician group. Through clear protocols and behavioral pressure, it demands surgeon alignment with the system as a whole and in return provides a stable work environment. It is not ideal for all surgeons and it is unclear whether it can be reproduced in a less structured setting.

RESUMEN

Aim: To highlight the role of the Masquelet technique as a limb salvage procedure for a neuropathic patient presenting with infected non-union of proximal tibia. Background: The management of an infected non-union in neuropathic patients is most challenging; with various treatment options available, the prognosis is often guarded. Case description: A 37-year-old male with chronic polyneuropathy, also possessing a contralateral midfoot Charcot arthropathy secondary to a history of alcohol abuse, developed infection after a proximal tibial osteotomy for a preceding mal-non-union of a proximal tibia fracture. The management included hardware removal, excision of necrotic bone, interim insertion of antibiotic-loaded bone cement followed by an acute shortening and revision of the internal fixation utilising a second surgical incision. Successful bone union and eradication of infection was achieved and maintained after 13 months follow-up. Conclusion: A successful outcome was achieved for an infected non-union of a long bone in a neuropathic patient using the Masquelet technique which was then followed with a second-stage removal of the spacer and shortening. By performing the revision ORIF surgery utilising a different skin incision in the setting of complicated previous surgical scars proved to be a viable technique towards reducing risk of recurrence of infection and a good outcome. Clinical significance: Utilisation of the Masquelet technique and limb shortening in a staged manner for the management of long bone infections in neuropathic patients has not been reported before and may be valuable in such demanding clinical situations.

RESUMEN

Cementation in hip arthroplasty is a common and reliable technique for achieving a stable bone-component interface. However, there are significant costs to the patient, surgeon, and hospital related to the use of cement. It has been previously demonstrated that increasing ambient room temperature and femoral component temperature decreases cement curing time. A protocol utilizing warmed saline irrigation within the surgical field and a warm saline bath for the femoral component was developed. We performed a comparative cohort study to investigate if this protocol reduced time to cement curing in an in vivo setting. Ten patients were enrolled in the experimental group and 11 patients in the control group. Time to cement curing was significantly lower in the experimental group (7.5 minutes vs. 11.1 minutes, p < 0.0001). The use of a simple and inexpensive warmed saline irrigation protocol during cemented hip arthroplasty decreases time to cement curing.

RESUMEN

Formal patient complaints and malpractice events involving orthopedic trauma surgeons (OTSs) can have substantial career implications. Our purpose was to analyze formal patient complaints, risk events, and malpractice events against OTSs during a 10-year period. We reviewed all formal patient complaints within our institution's patient advocacy database involving 9 fellowship-trained OTSs throughout a decade. Complaints were categorized using the Patient Complaint Analysis System. Potential risk and malpractice events involving the OTSs were recorded. A control group of all patients seen by the surgeons during the study period was created. Demographics between patients with complaints and the control group were analyzed, as were malpractice, risk, and complaint rates between the surgeons. Of 33,770 patients, 136 filed a formal complaint (0.40%). There were 29 malpractice claims and 2 malpractice lawsuits. The care and treatment domain accounted for the highest percentage of complaints (36%), followed by the access and availability domain (26%). Results of the logistic regression analysis indicated that private insurance (odds ratio, 1.58) and operative treatment (odds ratio, 3.65) were significantly associated with complaints. Despite statistically significant differences in the rates of complaint and risk events between surgeons, malpractice events did not differ. The rate of patient complaints within a large orthopedic trauma practice during a 10-year period was 0.40%. Patients with private insurance and those treated operatively were more likely to file a complaint. Whereas complaint rates among surgeons varied, there was no significant difference in the rate of malpractice events. Understanding patient complaint rates and categorizations may allow surgeons to target areas for improvement. [Orthopedics. 2023;46(2):121-127.].

RESUMEN

Whereas prior studies have aimed to define the utility of routine radiographs for the closed treatment of upper extremity fractures, it remains uncertain whether routine radiographs influence management decisions for nonoperative treatment of proximal humerus fractures (PHFs). The purpose of this investigation was to assess the utility of routine radiographic monitoring of closed PHFs in elderly patients initially indicated for nonoperative treatment. We identified all patients 65 years and older who had a PHF from 2016 to 2019. We excluded cases of pathologic fractures or peri-prosthetic fractures, nonunion, malunion, cases with insufficient follow-up, and cases for which surgery was indicated either in the emergency department or at the first orthopedic visit. After applying these exclusion criteria, 402 cases remained. We recorded baseline demographics and fracture descriptions and noted any conversion to operative treatment after the initial office visit. Two-part fractures were most common (56%). Of the 402 fractures indicated for nonoperative treatment, 21 (5%) were converted to operative management during the follow-up period. Nine fractures (2%) were converted to operative management within 30 days of the first office visit. Eight cases (2%) were converted to operative treatment more than 120 days after the initial office visit: 6 due to nonunion and 2 due to posttraumatic arthritis. For patients 65 years and older who undergo initial nonoperative treatment of a PHF, routine follow-up radiographs do not appear to alter management decisions. Given the risk and cost associated with routine radiographs, surgeons should consider forgoing these images in the absence of clinical concern. [Orthopedics. 2023;46(4):e244-e248.].

RESUMEN

INTRODUCTION: Proximal tibia fracture dislocations (PTFDs) are a subset of plateau fractures with little in the literature since description by Hohl (1967) and classification by Moore (1981). We sought to evaluate reliability in diagnosis of fracture-dislocations by traumatologists and to compare their outcomes with bicondylar tibial plateau fractures (BTPFs). METHODS: This was a retrospective cohort study at 14 level 1 trauma centers throughout North America. In all, 4771 proximal tibia fractures were reviewed by all sites and 278 possible PTFDs were identified using the Moore classification. These were reviewed by an adjudication board of three traumatologists to obtain consensus. Outcomes included inter-rater reliability of PTFD diagnosis, wound complications, malunion, range of motion (ROM), and knee pain limiting function. These were compared to BTPF data from a previous study. RESULTS: Of 278 submitted cases, 187 were deemed PTFDs representing 4% of all proximal tibia fractures reviewed and 67% of those submitted. Inter-rater agreement by the adjudication board was good (83%). Sixty-one PTFDs (33%) were unicondylar. Eleven (6%) had ligamentous repair and 72 (39%) had meniscal repair. Two required vascular repair. Infection was more common among PTFDs than BTPFs (14% vs 9%, p = 0.038). Malunion occurred in 25% of PTFDs. ROM was worse among PTFDs, although likely not clinically significant. Knee pain limited function at final follow-up in 24% of both cohorts. CONCLUSIONS: PTFDs represent 4% of proximal tibia fractures. They are often unicondylar and may go unrecognized. Malunion is common, and PTFD outcomes may be worse than bicondylar fractures.

RESUMEN

OBJECTIVE: To identify the patient, injury, and treatment factors associated with an acute infection during the treatment of open ankle fractures in a large multicenter retrospective review. To evaluate the effect of infectious complications on the rates of nonunion, malunion, and loss of reduction. DESIGN: Multicenter retrospective review. SETTING: Sixteen trauma centers. PATIENTS: One thousand and 3 consecutive skeletally mature patients (514 men and 489 women) with open ankle fractures. MAIN OUTCOME MEASURES: Fracture-related infection (FRI) in open ankle fractures. RESULTS: The charts of 1003 consecutive patients were reviewed, and 712 patients (357 women and 355 men) had at least 12 weeks of clinical follow-up. Their average age was 50 years (range 16-96), and average BMI was 31; they sustained OTA/AO types 44A (12%), 44B (58%), and 44C (30%) open ankle fractures. The rate FRI rate was 15%. A multivariable regression analysis identified male sex, diabetes, smoking, immunosuppressant use, time to wound closure, and wound location as independent risk factors for infection. There were 77 cases of malunion, nonunion, loss of reduction, and/or implant failure; FRI was associated with higher rates of these complications (P = 0.01). CONCLUSIONS: Several patient, injury, and surgical factors were associated with FRI in the treatment of open ankle fractures. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMEN

INTRODUCTION: Ankle fractures are one of the most prevalent musculoskeletal injuries, with a significant number requiring surgical treatment. Postoperative complications requiring additional interventions frequently occur during the early postoperative period. We hypothesize that there is a limited need for routine clinical and radiographic follow-up once the fracture is deemed healed. METHODS: IRB approval was obtained at four academic trauma centers. A retrospective chart review was done to identify adults with healed unimalleolar and bimalleolar ankle fractures treated surgically with at least 12 months of follow-up. Based on postoperative radiographs, changes in fracture alignment and implant position from radiographic union to final follow-up were documented. The average reimbursement for a final follow-up clinic visit and a set of ankle radiographs were estimated. RESULTS: A total of 140 patients met inclusion criteria. The mean age at injury was 49.5 years, and 67.9% of patients were female. The mean time to healing was 82.2 days (±33.5 days). After radiographic healing, one patient had radiographic changes but was asymptomatic and full weight bearing at their final follow-up. On average, our institution was reimbursed $46 to $49 for a follow-up clinic visit and $364 to $497 for a set of ankle radiographs. CONCLUSION: Given the average time to healing, there is limited utility in routine radiographic and clinical follow-up beyond 16 weeks in asymptomatic patients. In our series, this would result in a savings of $950 to $1,200 per patient. However, after ankle fractures were deemed healed, 0.7% patients had radiographic evidence of a change in implant position. Documenting this change did not modify the immediate course of fracture treatment. Surgeons will need to balance the need for routine follow-up with the potential economic benefits in reducing costs to the healthcare system.

RESUMEN

The surgical treatment of fractures about the knee in elderly patients and/or those with osteoporosis remains a problematic and evolving challenge to many orthopaedic surgeons. The fundamental issues of poor bone quality, poor hosts, and associated medical comorbidities makes treating these fractures difficult both in terms of the decision-making process and the chosen surgical technique. It is important to review major treatment challenges and the potential solutions for minimizing complications.

RESUMEN

OBJECTIVES: To evaluate the rate of, and reasons for, conversion of closed treatment of humeral shaft fractures using a fracture brace, to surgical intervention. DESIGN: Multicenter, retrospective analysis. SETTING: Nine Level 1 trauma centers across the United States. PATIENTS: A total of 1182 patients with a closed humeral shaft fracture initially managed nonoperatively with a functional brace from 2005 to 2015 were reviewed retrospectively from 9 institutions. INTERVENTION: Functional brace. MAIN OUTCOME MEASUREMENTS: Conversion to surgery. RESULTS: A total of 344 fractures (29%) ultimately underwent surgical intervention. Reasons for conversion included nonunion (60%), malalignment beyond acceptable parameters (24%), inability to tolerate functional bracing (12%), and persistent signs of radial nerve palsy requiring exploration (3.7%). Univariate comparisons showed that females and whites were significantly (P < 0.05) more likely to be converted to surgery. The multivariate logistic regression identified females as being 1.7 times more likely and alcoholics to be 1.4 times more likely to be converted to surgery (P < 0.05). Proximal shaft as well as comminuted, segmental, and butterfly fractures were also linked to a higher rate of conversion. CONCLUSIONS: This large multicenter study identified a 29% surgical conversion rate, with nonunion as the most common reason for surgical intervention after the failure of functional brace. These results are markedly different than previously reported. These results may be helpful in the future when counseling patients on the choice between functional bracing and surgical intervention in managing humeral shaft fractures. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

RESUMEN

OBJECTIVE: To compare the volar Henry and dorsal Thompson approaches with respect to outcomes and complications for proximal third radial shaft fractures. DESIGN: Multicenter retrospective cohort study. PATIENTS/PARTICIPANTS: Patients with proximal third radial shaft fractures ± associated ulna fractures (OTA/AO 2R1 ± 2U1) treated operatively at 11 trauma centers were included. INTERVENTION: Patient demographics and injury, fracture, and surgical data were recorded. Final range of motion and complications of infection, neurologic injury, compartment syndrome, and malunion/nonunion were compared for volar versus dorsal approaches. MAIN OUTCOME: The main outcome was difference in complications between patients treated with volar versus dorsal approach. RESULTS: At an average follow-up of 292 days, 202 patients (range, 18-84 years) with proximal third radial shaft fractures were followed through union or nonunion. One hundred fifty-five patients were fixed via volar and 47 via dorsal approach. Patients treated via dorsal approach had fractures that were on average 16 mm more proximal than those approached volarly, which did not translate to more screw fixation proximal to the fracture. Complications occurred in 11% of volar and 21% of dorsal approaches with no statistical difference. CONCLUSIONS: There was no statistical difference in complication rates between volar and dorsal approaches. Specifically, fixation to the level of the tuberosity is safely accomplished via the volar approach. This series demonstrates the safety of the volar Henry approach for proximal third radial shaft fractures. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMEN

Femoral neck fractures in children are rare injuries resulting from high-energy trauma. Different methods of treatment, lack of standard management protocols, and the high risk of complications make this injury one of the biggest challenges that an orthopaedic surgeon can face. This review focuses on the general aspects of the pediatric femoral neck fracture management as well as its complications and possible solutions.

RESUMEN

OBJECTIVE: To analyze the outcomes of tibial shaft fractures treated with a lateral parapatellar approach in the semiextended position for intramedullary nail insertion. DESIGN: Prospective cohort study. SETTING: Level I trauma center. PATIENTS AND METHODS: Seventy patients treated from March 2012 to July 2015 with intramedullary nailing (IMN) using an extraarticular lateral parapatellar approach in the semiextended position were reviewed. Patients were clinically and radiographically checked at a minimum follow-up of 24 months, and the following data were recorded: fracture healing, any residual deformity, nail-apex distance, range of motion of the treated knee together with the contralateral side, knee functional outcome, and residual knee pain. RESULTS: Twenty-four months after surgery, all patients were clinically and radiographically healed, with 2 cases of malalignment (angular deformity <10 degrees). The average range of motion of the treated knee was 0-130.6 degrees (±8.6 degrees) compared with 0-131.1 degree (±7.9 degrees) of the contralateral. Lysholm knee score was excellent for 57 patients, good for 11, and fair for 2. The mean residual pain was 0.6 (±1.1) according to the visual analogue scale. CONCLUSIONS: The described technique represents an effective option for IMN of tibial fractures. It is suitable for all tibial fractures, including proximal and distal. The results of our series demonstrate the effectiveness of this technique with nearly complete recovery of knee function and negligible incidence of anterior knee pain at a minimum follow-up of 24 months. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMEN

OBJECTIVES: To report on the final displacement after in situ percutaneous pinning for Garden type 1 and 2 fractures in height, femoral neck fracture collapse, and loss of offset. DESIGN: Retrospectively reviewed case series. SETTING: Three Academic Medical Centers. Boston University Medical Center (Level 1 Trauma Center), Lahey Hospital and Medical Center (Level 2 Trauma Center), and Geisinger Medical Center (level 2 Trauma Center). PATIENTS/PARTICIPANTS: One hundred thirty skeletally mature patients with 130 fractures (78 garden 1 and 52 garden 2) who were treated between January 2000 and January 2014 at participating hospitals with percutaneous pinning with a cannulated screw system to successful union after sustaining an intracapsular femoral neck fracture without complete displacement. INTERVENTION: In situ percutaneous pinning with 3 cannulated, partially threaded screws in an inverted triangle orientation. MAIN OUTCOME MEASUREMENTS: Femoral neck fracture collapse (mm), femoral height shortening (mm), and femoral offset shortening (mm). RESULTS: A total of 130 patients (81F, 49M), average age 72 years, sustained 78 Garden 1 and 52 Garden 2 femoral neck fractures. Maximal collapse occurred in the plane of the femoral neck. Thirty-three of 78 (42%) Garden 1 fractures and 33/52 (63%) Garden 2 fractures demonstrated >10 mm fracture collapse. The range of displacements was 0-39 mm as measured along the plane of the femoral neck. CONCLUSIONS: Garden 1 fractures collapse less frequently than Garden 2 fractures, but both have high rates of fracture collapse when treated to union with in situ percutaneous pin fixation. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

RESUMEN

With the increasing number of total knee arthroplasties (TKAs) being performed, the incidence of periprosthetic fractures adjacent to a TKA is rising. Minimally invasive plate osteosynthesis (MIPO) has proven to be successful for the biological fixation of many fractures. Advances in surgical instrumentation and techniques made MIPO possible for more complex fractures. Periprosthetic fractures are always complicated by problems of soft tissue incisions, scarring, and, of course, the arthroplasty components. MIPO techniques may be particularly suited to these injuries and may make the surgical repair of these fractures safer and more reliable. In this review, case examples are used to define the indications, preoperative planning, implant selection, complications, limitations, and challenges of MIPO for the treatment of periprosthetic fractures about the knee. When considering MIPO for any fracture, we recommend prioritizing an acceptable reduction with biological fixation and resorting to mini-open or open approach when necessary to achieve it. Awareness of the learning curve of the surgical technique, advances in implant designs, the tips and tricks involved, and the limitations of the MIPO is of paramount importance from the orthopaedic surgeon's perspective.

RESUMEN

BACKGROUND: The trend toward temporizing external fixation of complex fractures has resulted in increased expenditures for these devices. Increasing pressure to reduce health-care expenditures has led to exploration of reuse of equipment intended for single use. Devices must be tested and recertified prior to redeployment in hospital stock. We report the rate of manufacturer recertification and institutional cost savings associated with a reuse program approved by the United States Food and Drug Administration. METHODS: All Hoffmann-II external fixation components that had been removed at our institution during the study period were submitted to the manufacturer for visual inspection and mechanical testing. Pass rates for original components and previously recycled components were determined. With use of a conservative pass rate and the assumption of a maximum of three recertifications of each component, the total potential hospital savings on external fixation were calculated. RESULTS: The first pass rate was 76%. The second pass rate (i.e., the rate for components that had already been recertified once and had been sent for a second recertification) was 83%, but that rate was derived from a limited sample. On the basis of a conservative pass-rate estimate of 75%, the predicted average number of uses of a recyclable component was 2.7. The recertified components were sold back to our hospital at 50% of the original price. Because carbon-fiber bars and half-pins are not recycled, 85% of the charges expended on a new external fixation component are spent on portions of the system that are recyclable. The potential total savings on reusable components was found to be 32%, with a total savings of 27% for the whole external fixation system. No recertified components failed in clinical use over the course of the study. CONCLUSIONS: With the expansion of cost-control efforts, the recycling of medical devices appears inevitable. Previous data have demonstrated the safety of reuse of external fixation devices, and this study confirms that finding. Our paper demonstrates the real cost savings associated with a manufacturer-based testing and recertification program. Issues of voluntary participation in reuse programs, component ownership, and the impact of savings on patient charges are yet to be worked out by individual institutions.

RESUMEN

The role of intramedullary nailing of the femur and the timing for this procedure in the trauma patient with multiple injuries has been widely debated. Recent literature has advocated the idea of "damage control orthopaedics," promoting temporary external fixation for stabilization of long bone fractures in the acute setting. This paper advances an alternative to damage control orthopaedics, the option of rapidly executed small-diameter unreamed retrograde nailing of the femur for the patient with polytrauma who will be undergoing simultaneous surgery for other injuries. This technique offers the advantages of rapid stabilization performed under controlled circumstances in the operating room, without some of the disadvantages of using external fixation in this situation.
