Monolateral external fixation is a system for the stabilization, reduction, and manipulation of bone segments by means of bone anchorage consisting of pins fastened to an external frame. Monolateral external fixators in their various forms have the advantage that they allow the use of half-pins (bicortical pins that do not penetrate both sides of the soft tissue envelope), thereby avoiding major damage to the neurovascular structures contralateral to the insertion point. The simple structure of monolateral systems permits rapid application and simplified preoperative planning, both of which are features particularly appreciated in traumatology.

AbstractRhinoplasty is one of the most complicated operations that a plastic surgeon will encounter. In the early history of rhinoplasty, operations were done with a closed approach, and the structures were shrouded in mystery while surgeons relied on surface aesthetics for diagnosis and treatment. Finally, with the advent of the extended open approach, power tools, and piezosurgery, the whole bony pyramid can be directly visualized, shaped, and sculpted. Osteotomies can be done under direct vision with high precision. Using this approach, every part of the osseocartilaginous vault and nasal tip can now be directly observed, diagnosed, and surgically treated. However, this only occurs once the patient is in the operating room. This article will detail the diagnosis and treatment of the difficult soft-tissue envelope of the nose. It will also describe the use of ultrasonography for preoperative planning as well as postoperatively for diagnosis and treatment during the healing period and for planning possible revision and secondary surgery.

Calcaneus Fractures

Category: Trauma; Hindfoot Introduction/Purpose: High energy calcaneus fractures have significant soft tissue compromise and typically poor outcomes. The purpose of this study was to describe patient complications and outcomes, after undergoing staged treatment for high energy calcaneus fractures, including initial treatment with medial calcaneal external fixation followed by definitive reconstruction. Methods: A retrospective chart review with prospective data was performed from April 2013 to February 2019. Inclusion criteria for the study included: patients >18 years of age, closed Sanders III and IV fractures or open fractures of the calcaneus. Patients were initially treated with placement of a medial based external fixator with closed reduction. Once the soft tissue envelope had improved, definitive fixation was performed, either ORIF or ORIF with primary subtalar fusion. Results: There were a total of 15 patients that met inclusion criteria for the study. 9 of the fractures were open and 6 were closed. The medial calcaneal external fixation (ex-fix) was placed at a mean of 2.0 (0-12) days after initial injury. The definitive procedure occurred at a mean of 23.6 (12-42) days after ex-fix placement. 11 of the patients underwent calcaneus fracture ORIF with primary subtalar (ST) fusion and 4 patients were treated with calcaneus fracture ORIF alone. 14 (93%) of the patients showed radiographic union at an average of 6.7 months. Mean PROMIS scores showed improvement in physical function, mood, and a decrease in pain at an average of 19 (5-72) months after initial injury. The average VAS pain score was 3.5 (0-7). Conclusion: A staged protocol for high-energy and open calcaneal fractures is an effective tool in treating these difficult injuries. It allows the soft tissues to improve while maintaining length and alignment of the fracture for definitive fixation and minimizing complications. There were improvements in physical function, mood, and a decrease in pain at final follow-up of almost 2 years. [Table: see text]

Percutaneous Repair

INTRODUCTION AND OBJECTIVES: Calcaneal fractures are a serious injury with significant associated morbidity. Bilateral calcaneal fractures complicate issues even further, due to the physical disability that the patient is left with. One of the major issues with any calcaneal fracture is the risk of soft tissue compromise caused by the traumatic nature of the injury. A percutaneous approach allows the soft tissue envelope to remain viable, while still fixating the fractures. The purpose of this presentation is to highlight the use of percutaneous repair, the role of external fixation in calcaneal fractures, and lastly discuss the outcome for this particular patient. METHODS: A 26 year-old male presented to the office with bilateral calcaneal fractures, approximately 1 week after sustaining a fall from a height of 12 feet. The patient was brought to the operating room after spending approximately 2 weeks in bilateral posterior splints with Jones compressive dressings. The right calcaneal fracture was fixated percutaneously with 4 screws. The left calcaneal fracture was fixated percutaneously with 3 screws, as well as an Ilizarov external fixator. Approximately 8 weeks later, the patient returned to the operating room for removal of the external fixator and a cast application to the left lower extremity. RESULTS: The patient continued to progress and was subsequently transitioned into bilateral CAM walkers. In the following weeks, the patient was again upgraded to full weight-bearing with physical therapy. The fracture sites were completely consolidated with minimal to no pain in his bilateral heels and full ambulation. CONCLUSIONS: Percutaneous repair, along with external fixation, offers a viable alternative to ORIF for calcaneal fractures. A percutaneous approach also does not disrupt the potentially fragile soft tissue envelope in a calcaneal fracture. Although this outcome is positive, larger controlled studies are needed to confirm percutaneous approaches and external fixation in the realm of a calcaneal fracture.

Calcaneus Fractures

Category: Hindfoot, Trauma Introduction/Purpose: Calcaneus fractures are common injuries of the foot and account for approximately sixty percent of all tarsal bone fractures. Anatomic reduction of the articular surface is associated with good long-term outcomes. Unfortunately, there is a high rate of complications following surgical fixation due to the fragile soft tissue envelope surrounding these injuries. External fixation of joint depression calcaneus fractures allows for restoration of morphology and preservation of soft tissues. The purpose of this work is to determine if acute external fixation in the management of joint depression calcaneus fractures leads to decreased postoperative complications and better outcomes. Methods: Patients were identified using the appropriate procedure codes over a ten year span at a level one trauma center. Those under the age of eighteen and underwent nonoperative treatment were excluded. Electronic medical records were reviewed to obtain, basic demographic data, comorbidities, and injury specifics. Calcaneus fractures were classified as open or closed and using the Essex-Lopresti classification system. Operative reports were reviewed to determine which patients initially underwent external fixation versus open reduction internal fixation (ORIF), furthermore any staged operative interventions were also noted. Electronic records were also reviewed to determine the length of follow up and incidence of postoperative complications. Bivariate analysis was used to identify an association between collected variables and postoperative complications (wound dehiscence, hardware failure, infection, nonunion). Multivariate logistic regression analysis was used to determine if patients treated with acute external fixation were associated with lower postoperative complication rates. Results: 152 calcaneus fractures were identified and included for analysis. The average age was thirty-eight and the majority of patients were male (111/152 = 73%). Average follow up was approximately five months. Seventeen percent (26/152) were open fractures. Twenty-six (17%) were treated initially with external fixation and eleven of these were a staged ORIF. The overall complication rate was 11% (17/152) with the most common complication being wound dehiscence. Only one complication occurred in the group initially managed with external fixation. Statistical analysis revealed that open fractures were associated with increased postoperative complication rates in a bivariate and multivariate model. Conclusion: External fixation of joint depression calcaneus fractures restores height and preserves the soft tissue envelope. Although there was only one complication in the external fixation group, the difference in complication rates was not statistically significant based on initial treatment. The low number of patients treated with external fixation initially and the short follow up are limitations of this study. Further work is needed with a larger patient cohort in a prospective setting. Acute external fixation may prove to be a useful tool to help prevent postoperative complications following joint depression calcaneus fractures.

AbstractAlloplastic facial transplantation has become a new rung on the proverbial reconstructive ladder for severe facial wounds in the past couple of decades. Since the first transfer including bony components in 2006, numerous facial allotransplantations across many countries have been successfully performed, many incorporating multiple bony elements of the face. There are many unique considerations to facial transplantation of bone, however, beyond the considerations of simple soft tissue transfer. Herein, we review the current literature and considerations specific to bony facial transplantation focusing on the pertinent surgical anatomy, preoperative planning needs, intraoperative harvest and inset considerations, and postoperative protocols.

Background: To date, there is still no consensus on what soft tissues must be preserved and what structures can be safely released during total knee arthroplasty (TKA) with a medially stabilized implant. Objective: The aim of this study was to analyze the effect of a progressive selective release of the medial and lateral soft tissues in a knee implanted with a medially stabilized prosthesis. Method: Six cadaveric fresh-frozen full leg specimens were tested. In each case, kinematic pattern and mediolateral laxity were measured in three stages: firstly, prior to implantation; secondly, after the implantation of the trial components, but before any soft tissue release; and thirdly, progressively as soft tissue was released with the trial implant in place. The incremental impact of each selective release on knee balance was then analyzed. Results: In all cases sagittal stability was not affected by the progressive release of the lateral soft tissue envelope. It was possible to perform progressive lateral release provided the anterior one-third of the iliotibial band (ITB) remained intact. Progressive medial release could be performed on the medial side provided the anterior fibers of the superficial medial collateral ligament (sMCL) remained intact. Conclusion: The medially conforming implant remains stable provided the anterior fibers of sMCL and the anterior fibers of the ITB remain intact. The implant’s sagittal stability is mainly dependent on its medial ball-in-socket design.

Revision Tka

For multifactorial reasons an estimated 20% of patients remain unsatisfied after total knee arthroplasty (TKA). Appropriate tension of the soft tissue envelope encompassing the knee is important in total knee arthroplasty and soft tissue imbalance contributes to several of the foremost reasons for revision TKA, including instability, stiffness and aseptic loosening. There is debate in the literature surrounding the optimum way to achieve balancing of a total knee arthroplasty and there is also a lack of an accepted definition of what a balanced knee replacement is. It may be intuitive to use the native knee as a model for balancing; however, there are many difficulties with translating this into a successful prosthesis. One of the foundations of TKA, as described by Insall, was that although the native knee has more weight transmitted through the medial compartment this was to be avoided in a TKA as it would lead to uneven wear and early failure. There is a focus on achieving symmetrical tension and pressure and subsequent ‘balance’ in TKA, but the evidence from cadaveric studies is that the native knee is not symmetrically balanced. As we are currently trying to design an implant that is not based on its anatomical counterpart, is it possible to create a truly balanced prosthesis or to even to define what that balance is? The authors have reviewed the current evidence surrounding TKA balancing and its relationship with the native knee. Cite this article: EFORT Open Rev 2018;3:614-619. DOI: 10.1302/2058-5241.3.180008.

The new Morpheus8 is a novel external RFAL device that uses the proven soft tissue contraction of BodyTite in an external, non-invasive procedure. This external RF applicator, which is also powered by BodyTite, inserts up to 40 positively charged, coated electrodes 8 mm into the subcutaneous, soft tissue envelope. A monopolar ablative lesion is generated from the tip of the electrode, stimulating contraction of the FSN and adipose coagulation. The RF then flows up to the distant negative, return electrodes on the surface of the skin, providing a non-ablative thermal stimulation to the papillary dermis. The “burst” feature of the Morpheus8, delivers simultaneous multiple levels of internal coagulation in a single one second pulse, amplifying the adipose ablation and contraction effect. Studies, show, that the combination of BodyTite internal thermal coagulation and external Morpheus8 at the time of liposuction can result in 60–70% area skin contraction, greatly improving the soft tissue contours and Body shaping outcomes following lipo-contouring procedures.

Hematoma refers to the collection or extravasation of blood, usually clotted, in a closed tissue space. It is caused by leakage from local vessels damaged by blunt trauma, local injury, or surgical dissection. In the postoperative phase, a hematoma often results in edema, pain, wound dehiscence, infection, and scarring of the surgical wound. We describe a 44-year-old woman who developed severe complications, including hematoma, abscess, failure of internal fixation, and loss of soft-tissue structures, after hallux abducto valgus surgery. Hospitalization was required for infection control, soft-tissue coverage through negative-pressure wound therapy, and first metatarsophalangeal joint stabilization through external fixation. Early recognition of the signs of infection and hematoma can help decrease the incidence of postoperative complications. (J Am Podiatr Med Assoc 97(5): 410–414, 2007)
