Bipolar Pedicled Latissimus Dorsi Flap for Soft-Tissue Coverage and Restoration of Elbow Function.

Bipolar latissimus dorsi transfer has been considered a viable option for the restoration of elbow flexion in patients with large traumatic defects of the anterior arm compartment. Advantages of bipolar transfer of the latissimus include stabilization of the anterior shoulder joint in addition to recreating the biceps for a direct line of pull in restoring elbow flexion with minimal donor site morbidity. Previous literature in bipolar latissimus transfer has demonstrated good outcomes in elbow flexion against gravity, range of motion, and patient satisfaction. We present a step-by-step demonstration of a bipolar pedicled latissimus dorsi transfer for restoration of elbow function and soft-tissue coverage for large traumatic defects to the anterior compartment of the arm.

Technique for All-Inside Anterior Cruciate Ligament Reconstruction Using Quadrupled Semitendinosus and Gracilis Autograft.

Anterior cruciate ligament (ACL) injuries are common to athletes and non-athletes alike. Whereas the literature has historically supported bone-patellar tendon-bone as the gold standard for active patients who elect to undergo ACL reconstruction, other studies have suggested that soft-tissue grafts do not increase the risk of rerupture. Because graft diameter has a direct effect on revision rates, we share a technique for all-inside ACL reconstruction using quadrupled semitendinosus and gracilis autograft that allows for a predictable, robust graft. Reproducible steps of graft harvesting, tunnel preparation, graft passage, and fixation are shared to achieve a robust anatomic reconstruction.

Teres Major and Latissimus Dorsi Repair With Biceps Tenodesis Utilizing Cortical Suspensory Fixation Buttons.

Teres major (TM) and latissimus dorsi (LD) ruptures are relatively rare in the general population and have primarily been observed in overhead throwing athletes. Although the gold standard of care has traditionally been nonoperative, surgical repair of TM and LD tendon ruptures has become increasingly prevalent in high-level athletes who fail to return to play. Literature is scarce regarding operative repair of these tendon ruptures. Therefore, our goal is to present a potential technique for open repair to surgeons who may be faced with this unique orthopedic injury. Our technique details an open TM and LD repair, in addition to biceps tenodesis, using cortical suspensory fixation buttons with a combined anterior and posterior approach.

Quadriceps Tendon Reconstruction With Achilles Tendon Bone Block Allograft.

Chronic quadriceps tendon ruptures are relatively uncommon albeit debilitating injuries to the knee extensor mechanism. Previous literature demonstrates worse reported outcomes with delayed surgical intervention, and no gold-standard technique currently exists for managing chronic quadriceps tendon ruptures. The goal of this technique is to provide orthopaedic surgeons an additional option that may provide a greater mechanical load to failure and greater allograft acceptance for cases with large tendon gapping or poor tissue quality that may not be viable to other lengthening techniques. We describe the repair of a chronic quadriceps tendon rupture using an Achilles tendon bone block allograft.

A Case of Lyme Carditis With Variable Heart Block Successfully Treated With Oral Doxycycline.

A 39-year-old male without significant past medical history presented with three weeks of worsening fatigue, migratory arthralgia, rash, and unilateral facial weakness after spending three months in Vermont. Serology showed positive Lyme titers 1:64 for both IgM and IgG. EKG on presentation showed a P-R interval of 384 ms, and the patient was admitted for concern of Lyme carditis. Serial EKGs obtained throughout his stay demonstrated variability between first- and second-degree heart blocks. After consultation with Infectious Disease, he was transitioned to oral doxycycline to complete a 21-day course. The patient's heart block and other symptoms had resolved on follow-up after the treatment course had been completed.

Revision Achilles Tendon Repair Using Posterior Tibial Tendon Allograft and Flexor Hallucis Longus Transfer.

Achilles tendon ruptures are common injuries seen by orthopaedic surgeons. A myriad of surgical options have been used in the management of Achilles tendon ruptures, but currently no gold standard exists. Re-rupture of Achilles tendon injuries occurs 1.7% to 5.6% of the time, and there has been no direct relationship demonstrated between complications and repair techniques used. The aim of this technique is to provide a method of fixation for the patient with an Achilles tendon re-rupture that provides a stable repair construct and mitigates the potential sequela of re-rupture. We describe the treatment of an Achilles tendon re-rupture with the use of a flexor hallucis longus tendon transfer and posterior tibial tendon allograft for repair of an 8.5 cm tendon gap.

Patient Utilization of Online Information and its Influence on Orthopedic Surgeon Selection: Cross-sectional Survey of Patient Beliefs and Behaviors.

BACKGROUND: Patient attitudes and behavior are critical to understand owing to the increasing role of patient choice. There is a paucity of investigation into the perceived credibility of online information and whether such information impacts how patients choose their surgeons. OBJECTIVE: The purpose of this study was to explore the attitudes and behavior of patients regarding online information and orthopedic surgeon selection. Secondary purposes included gaining insight into the relative importance of provider selection factors, and their association with patient age and education level. METHODS: This was a cross-sectional study involving five multispecialty orthopedic surgery groups. A total of 329 patients who sought treatment by six different orthopedic surgeons were asked to anonymously answer a questionnaire consisting of 25 questions. Four questions regarded demographic information, 10 questions asked patients to rate the importance of specific criteria regarding the selection of their orthopedic surgeon (on a 4-point Likert scale), and 6 questions were designed to determine patient attitude and behaviors related to online information. RESULTS: Patient-reported referral sources included the emergency room (29/329, 8.8%), friend (42/329, 12.8%), insurance company (47/329, 14.3%), internet search/website (28/329, 8.5%), primary care physician (148/329, 45.0%), and other (34/329, 10.3%). Among the 329 patients, 130 (39.5%) reported that they searched the internet for information before their first visit. There was a trend of increased belief in online information to be accurate and complete in younger age groups (P=.02). There was an increased relative frequency in younger groups to perceive physician rating websites to be unbiased (P=.003), provide sufficient patient satisfaction information (P=.01), and information about physician education and training (P=.03). There was a significant trend for patients that found a surgeon's website to be useful (P<.001), with the relative frequency increased in younger age groups. CONCLUSIONS: This study shows that insurance network, physician referrals, appointment availability, and office location are important to patients, whereas advertising and internet reviews by other patients were considered to be not as helpful in choosing an orthopedic surgeon. Future studies may seek to identify obstacles to patients in integrating online resources for decision-making and strategies to improve health-seeking behaviors.

Triple Tendon Transfer of the Levator Scapulae, Rhomboid Major, and Rhomboid Minor to Reconstruct the Paralyzed Trapezius.

Trapezius paralysis is a relatively uncommon condition that orthopaedic surgeons may encounter. Despite the paucity, it presents as a debilitating condition with sequelae of poor function and deconditioning. Conservative management often fails, and patients are left with limited surgical options. In the current Eden-Lange procedure, tendon transfer of the levator scapulae, rhomboid major, and rhomboid minor is performed to reconstruct the paralyzed trapezius. Although good outcomes have been found with this technique, the pull of the levator scapulae and the pull of the rhomboids are in opposition to each other, which presents a biomechanical problem for patients because this fails to re-create the natural function of the trapezius. In this article, we present a technique that is a modification of the Eden-Lange triple tendon transfer using suture bone bridges in which the levator scapulae is transferred as with the original procedure; however, the rhomboids with bony bridges are transferred to a different point along the medial scapula. Our technique therefore may better re-create the natural pull of the fibers of the upper, middle, and lower trapezius.

Achilles Tendon Rip-Stop SpeedBridge Repair.

Achilles tendon injuries have been on the rise secondary to our increased participation in sports, increase in societal obesity rates, and the growing elderly population. There has been disagreement in recent years about whether to treat injuries such as Achilles tendon ruptures operatively or nonoperatively with aggressive functional rehabilitation. For those opting to surgically manage Achilles tendon ruptures, insertional Achilles tendonitis, or augment the described SpeedBridge Achilles tendon repair, we propose a modified rip-stop technique. The goal of this technique is to provide a biomechanical advantage to our current operative interventions for these injuries, a greater load-to-failure and a speedier, more reliable return to sport in our athletic populations.

Bicortical Titanium Tenodesis Button With Double-Row Fixation for the Treatment of Proximal Rectus Femoris Avulsion: Review of Literature and Surgical Technique.

In adult populations, rectus femoris avulsions are reported in professional soccer and football players but are noted to be exceptionally rare. No gold standard or recommendations exist for this injury; however, in cases of avulsion at the anterior inferior iliac spine, positive outcomes appear to result from rest, immobilization, and rehabilitation. Surgery is typically reserved for cases with large retractions of bone fragments or unsuccessful nonoperative treatment. Surgical treatment methods vary from direct suture repair to single- and double-row bone suture placement and even muscle-muscle repair. We present our technique using a bicortical tenodesis button with double-row fixation for the treatment of a severely retracted rectus femoris tendon avulsion in a high-level athlete.

Treatment of Severe Ankle and Hindfoot Deformity: Technique Using Femoral Head Allograft for Tibiotalocalcaneal Fusion Using a Cup-and-Cone Reamer.

Limb shortening due to structural bone loss in tibiotalocalcaneal arthrodesis is a concern that can negatively impact the patient's gait and weight-bearing. To aid in preventing the risk of limb shortening, the use of a femoral head allograft and intramedullary nail in tibiotalocalcaneal arthrodesis has been shown to successfully preserve limb length in patients with structural bone deficits. We present our technique using a femoral head allograft with a cup-and-cone reamer for the treatment of severe ankle and hindfoot deformity.

Low-Profile, Suture Anchor Tension Band Construct for Olecranon Fractures and Osteotomies.

Olecranon fractures are common and frequently require surgical intervention when they are displaced or unstable. Treatment is largely dictated by fracture type and surgeon preference. Traditional methods of fixation, including tension band wiring and locking plate fixation, have adequate union rates; however, both techniques are associated with increased reoperation rates due to symptomatic hardware. The aim of this article is to describe a technique using a low-profile, suture anchor tension band construct for simple transverse olecranon fractures, triceps avulsions, and olecranon osteotomies. The goal of this technique is to produce stable fixation and allow early range of motion while mitigating the reoperation rate caused by symptomatic or prominent hardware with olecranon plate fixation during fracture and olecranon osteotomies.

Identifying Intra-Articular Pathology With Arthroscopy Prior to Open Ankle Fracture Fixation.

PURPOSE: To assess the prevalence of intra-articular findings with ankle arthroscopy in patients undergoing operative fixation for ankle fractures. METHODS: This is a retrospective review of ankle fractures that were treated with arthroscopy and open reduction and internal fixation by a single surgeon. Between August 2016 and July 2018, operative reports, office notes, and images were reviewed to identify intra-articular pathology and fracture type. An analysis was performed with regard to fracture type, presence and location of osteochondral lesions, loose-bodies, syndesmotic injury, and deltoid injury. RESULTS: Fifty-seven ankle fractures were identified that met inclusion criteria. In total, 84.2% of the fractures had intra-articular pathology, most commonly a syndesmotic injury followed by presence of intra-articular loose bodies and osteochondral defects. CONCLUSIONS: In our study, use of arthroscopy before open ankle fracture fixation identified intra-articular pathology in 84.2% of subjects. The most common pathology was syndesmotic injury. The addition of an arthroscopic assessment in patients with operatively treated ankle fractures may help improve treatment provided to patients during ankle fracture surgery. LEVEL OF EVIDENCE: Level 4 Therapeutic Case Series.

Anatomic relationship of the sural nerve when performing Achilles tendon repair using the percutaneous Achilles repair system, a cadaveric study.

BACKGROUND: Minimally invasive techniques for Achilles tendon repair are increasing due to reports of similar rerupture rates using open and percutaneous techniques with fewer wound complications and quicker recovery with percutaneous methods. The goal of this study was to investigate quantitatively the relationship and risk of injury to the sural nerve during Achilles tendon repair when using the Percutaneous Achilles Repair System (PARS) (Arthrex®, Naples, FL), by recording the distance between the passed needles and the sural nerve as well identifying any direct violation of the nerve with needle passage or nerve entrapment within the suture after the jig was removed. The hypothesis of the study is that the PARS technique can be performed safely and without significant risk of injury to the sural nerve. METHODS: A total of five needles were placed through the PARS jig in each of 10 lower extremity cadaveric specimens using the proximal portion after simulation of a midsubstance Achilles tendon rupture. Careful dissection was performed to measure the distance of the sural nerve in relation to the passed needles. The sutures were then pulled out through the incision as the jig was removed from the proximal portion of the tendon and observation of the suture in relation to the tendon was documented. RESULTS: Of the 10 cadaveric specimens, none had violation of the sural nerve. Zero of the 50 (0%) needles directly punctured the sural nerve. In addition, upon retraction of the jig, all sutures were noted to reside within the tendon sheath with no entrapment of the sural nerve noted. CONCLUSION: This study demonstrated the variable course of the sural nerve and identifies the potential risk for sural nerve injury when using the PARS for Achilles tendon repair. However, this study provides additional evidence of safety from an anatomic standpoint that explains the outcomes demonstrated in the clinical trials. With this information the authors believe surgeons should feel comfortable they can replicate those outcomes while minimizing risk of sural nerve injury when the technique is used correctly.

An Alternative One-Stage Exchange Arthroplasty Technique: For the Chronic Infected Total Hip.

Background There are various algorithms for the treatment of prosthetic joint infections (PJI). Currently, a two-stage hip exchange is considered the "gold standard" of care for treatment of chronic hip PJIs. However, there has been recent debate whether a one- or two-stage exchange offers the correct treatment. One-stage exchange arthroplasty has particularly gained interest due to less morbidity, mortality, and functional impairment. Methods In a retrospective case series, the outcome of patients with chronic hip PJIs treated with our one-stage exchange arthroplasty was analyzed. Between January 2015 and January 2020, eight patients underwent a one-stage exchange hip arthroplasty by a single surgeon at a single institution for a chronically infected total hip arthroplasty (THA). Original diagnosis of PJI was made in accordance with the 2011 version of the Musculoskeletal Infection Society (MSIS) criteria. The femoral stem was cemented with antibiotic-impregnated cement, and the polyethylene acetabular liner was cemented directly onto the acetabular bone with antibiotic-impregnated cement. Results Of the eight patients, three were female and five were male with a mean age of 70.5 years (SD 11.2, range 53-87). Six patients (75%) had infection eradication with retention of a stable implant and no additional surgery at a mean follow-up of 35.7 months (range 17-50). One patient (12.5%) underwent closed reduction for a dislocated THA at one month; however, this patient remained infection-free at the most recent follow-up of 41 months. One patient (12.5%) who was the oldest patient (87 years) died 18 days postoperatively. Overall, all living patients (87.5%) retained their one-stage exchange THA. One patient (12.5%, CI 95% 0.3-52.7) required additional surgery in the form of a closed reduction and zero patients (0.0%, CI 95% 0.0-36.9) required additional open surgery.  Conclusion Single-stage exchange arthroplasty with an antibiotic-impregnated cemented femoral stem and antibiotic-impregnated cemented polyethylene acetabular liner may be a useful option for the treatment of chronic hip PJIs. Our case series provides evidence that infection eradication and function preservation are possible using our one-stage exchange arthroplasty technique in a chronically infected THA. However, a multi-center study with randomization is necessary to further validate our results.

Ulnar Collateral Ligament Reconstruction Technique Utilizing Suture Tape Augmentation.

The prevalence of ulnar collateral ligament injuries and reconstructions among overhead throwing athletes has significantly risen in recent years. Surgical reconstruction has become the main treatment modality for athletes who have failed conservative treatment and wish to return to their sport. There has been an increased interest in graft augmentation in ligament reconstruction surgeries as surgeons search for ways to decrease the chance of graft failure. Augmented graft techniques have been described for other procedures. We present a technique that incorporates a cross-linked suture tape into either a palmaris longus or gracilis tendon autograft or allograft for ulnar collateral ligament reconstruction. This may allow for a biomechanically stronger construct because it appears this is the case in other settings. The goal is that this would lead to decreased rates of failure or possibly allow athletes to return at an accelerated rate.

Patellar Tendon Graft Anterior Cruciate Ligament Reconstruction Technique With Suture Tape Augmentation.

Suture tape augmentation for repair and in combination with reconstruction with grafts has been described for multiple procedures. To date, no description of a patellar tendon graft anterior cruciate ligament reconstruction with an augmented graft has been published. This Technical Note details a technique we developed to incorporate a cross-linked suture tape into a patellar tendon graft.

Self-powered therapeutic release from conducting polymer/graphene oxide films on magnesium.

Magnesium's complete in vivo degradation is appealing for medical implant applications. Rapid corrosion and hydrogen bubble generation along with inflammatory host tissue response have limited its clinical use. Here we electropolymerized a poly (3,4-ethylenedioxythiophene) (PEDOT) and graphene oxide (GO) film directly on Mg surface. GO acted as nano-drug carrier to carry anti-inflammatory drug dexamethasone (Dex). PEDOT/GO/Dex coatings improved Mg corrosion resistance and decreased the rate of hydrogen production. Dex could be released driven by the electrical current generated from Mg corrosion. The anti-inflammatory activity of the released Dex was confirmed in microglia cultures. This PEDOT/GO/Dex film displayed the ability to both control Mg corrosion and act as an on demand release coating that delivers Dex at the corrosion site to minimize detrimental effects of corrosion byproducts. Such multi-functional smart coating will improve the clinical use of Mg implants. Furthermore, the PEDOT/GO/Drug/Mg system may be developed into self-powered implantable drug delivery devices.

Staged Treatment of Infected Tibiotalar Fusion Using a Combination Antibiotic Spacer and Antibiotic-Coated Intramedullary Nail.

Pilon fractures are notoriously difficult injuries to treat. The current published data on salvage procedures after failed pilon fractures includes both total ankle arthroplasty (TAA) and tibiotalar fusion, each with its own specific indications. However, no acceptable treatment algorithm addressing the complications of these limb salvage procedures is available. We present the case of a 23-year-old patient, who sustained a complex pilon fracture after a motor vehicle accident. The patient was referred to our institution after an initial fixation attempt, followed by subsequent failed TAA, which was complicated by an infected fusion attempt. We describe a staged treatment approach to clearing the infection and obtaining the final fusion goals.
