Fixation of Proximal Tibial Fractures with Intramedullary Nail and Immediate Weightbearing: A Beneficial Alternative.

Newer intramedullary (IM) nails have become another option in the fixation of proximal tibia fractures. There is limited data on the successful use of these implants in intra-articular and extra-articular fractures of the proximal tibia, and no studies assessing the ability of these implants to maintain alignment with early weight bearing. Our objective was to determine whether immediate weight bearing after IM fixation, with or without supplemental plate or screw fixation, of proximal third tibial fractures (OTA/AO 41A-C) results in a change in alignment prior to union. 35 patients with 39 proximal tibia fractures from 2015 to 2020, all treated with IM nailing with or without supplemental plate or screw fixation, all made weight-bearing as tolerated following surgery, were included. The main outcomes were change in medial proximal tibial angle (MPTA) and posterior proximal tibial angle (PPTA) from initial post-operative films to final follow up. 12 fractures were OTA/AO 41 type A, 14 were type B, and 13 were type C. Mean initial MPTA was 87.0 +/-2.53 degrees, while mean initial PPTA was 79.6 +/- 3.50 degrees. The mean change in MPTA was 0.048 +/- 2.8 degrees (P=0.92), and mean change in PPTA was 0.264 +/- 3.67 degrees. 92.3% of fractures had normal final coronal plane alignment, with MPTA between 85.0 and 90.0 degrees. 89.7% of fractures had normal final sagittal plane alignment, with PPTA between 77.0 and 84.0 degrees. No patients required reoperation for malalignment. In OTA/AO type 41 fractures, immediate weight bearing after IM nail fixation, with or without supplemental plate or screw fixation when indicated, leads to minimal change in final coronal or sagittal alignment, and was well tolerated in most patients.

Injuries Common to the Brazilian Jiu-Jitsu Practitioner.

BACKGROUND: Brazilian jiu-jitsu (BJJ) is a martial art that focuses on ground combat, emphasizing skill over strength and submission over striking. The purpose of this study is to evaluate the nature of injuries affecting practitioners of BJJ in the settings of competition, training, and conditioning. METHODS: An online survey was created to collect demographic and injury-specific information. This survey was distributed to the 234 schools in the United States registered with the International Brazilian Jiu-Jitsu Federation (IBJJF). The survey was also distributed to local BJJ schools and at local tournaments in the Greater New York City area. Data from a total of N=56 participants were recorded for this survey. RESULTS: The majority of participants were male (n=44, 78.6%) and amateur competitors (n=29, 51.8%) with an average duration of BJJ training of 6.9 ± 5.9 years. The majority of participants (82.1%) train at least six hours per week and compete in an average of 4.6 ± 2.5 competitions per year. The most common injuries were to the finger/hand (78.6%) and knee (61.5%). The most commonly reported fracture was of the hand/fingers (n=6). Of the 156 total injuries reported, 133 (85.3%) occurred during practice or training rather than in competition and 76 (48.7%) required medical attention. Few injuries required surgical intervention. CONCLUSIONS: This study provides novel information regarding injury characteristics of BJJ practitioners with respect to the level of training and use of protective equipment that can guide expectations and management for this unique group of athletes. Amateur BJJ practitioners are the most commonly injured, and largely experience injuries of the upper extremities during training or conditioning rather than during competition.

Treatment of an Infected Tibial Shaft Non-Union Using a Novel 3D-Printed Titanium Mesh Cage: A Case Report.

Treating large bone defects resulting from trauma, tumors, or infection can be challenging, as current methods such as external fixation with bone transport, bone grafting, or amputation often come with high costs, high failure rates, high requirements for follow-up, and potential complications. In this case report, we present the successful treatment of a complicated, infected tibial shaft non-union by using a personalized three-dimensional (3D)-printed titanium mesh cage. This case adds to the existing body of literature by demonstrating successful integration of bone into a titanium implant and a demonstration of immediate postoperative weight bearing in the setting of suboptimal operative and psychosocial conditions. Futhermore, this report highlights the flexibility of 3D-printing technology and its ability to allow for continued limb salvage, even after a planned bone transport procedure has been interrupted. The use of 3D-printed implants customized to the patient's specific needs offers a promising new avenue for treating complex tibial pathologies, and the technology's versatility and ability to be tailored to individual patients makes it a promising tool for addressing a wide range of bone defects.

Salvage of a recalcitrant humeral shaft septic nonunion using a linked nail-plate fixation construct with intercalary allograft.

Open humeral shaft fractures comprise approximately 2% of all fractures of the humerus. Nearly 20% of open humeral shaft fractures will develop deep infection, increasing the risk of nonunion regardless of treatment method. Recalcitrant septic nonunion of the humeral shaft is a complex and challenging problem. Operative treatment should aim to eradicate infection, address bony defects, and establish a stable construct that affords early motion. We describe the case of a 38-year-old male with a recalcitrant humeral shaft septic nonunion following fixation of an open humeral shaft fracture. Management of the infection consisted of periodic surgical debridement and IV antibiotics, resulting in a 10 cm segmental defect. Definitive fixation was achieved using the combination of an antegrade intramedullary nail, intercalary femoral shaft allograft, compression plating, and autologous bone graft. In addition to achieving bony union, the patient regained his pre-injury ROM and function, which was clinically sustained at 2-year follow-up.

A graphic guide to the percutaneous tripod acetabular reconstruction for metastatic cancer.

Symptomatic peri-acetabular metastatic lesions are often treated with open surgery such as modified Harrington procedures. In an effort to avoid surgical complications inherently associated with open surgical approaches, we developed and recently reported a novel Tripod percutaneous screw technique. The tripod technique is minimally invasive and was found to yield excellent outcomes regarding both pain control and functionality. The procedure is performed in a standard operative theater using fluoroscopic guided percutaneous screws. Despite the simplicity of intraoperative set-up and instrumentation, it is technically demanding. Obtaining the correct fluoroscopic views and troubleshooting intraoperative hurdles can be challenging for even an experienced orthopedic surgeon. The technique and bony conduits were previously described in the trauma literature, however, there are key points of difference in the setting of metastatic disease. Here we provide a compilation of a stepwise graphic guide for the tripod model in the setting of metastatic peri-acetabular lesions, as well as the tips and tricks based on our own experience. These encompass preoperative preparation, operating room settings, intraoperative fluoroscopic guidance, postoperative care, and subsequent conversion to a cemented total hip arthroplasty, if needed.

Establishing the validity of surface topography for assessment of scoliosis: a prospective study.

STUDY DESIGN: Descriptive survey. OBJECTIVES: Compare radiographic parameters measured using surface topography (ST) with those obtained radiographically to determine the validity of ST for scoliotic assessment. METHODS: While anterior-posterior radiography is the gold standard for diagnosing scoliosis, repeated radiographic use is associated with increased carcinogenicity. Studies have thus focused on radiation-free systems, including ST, to calculate the scoliotic angle. Seventeen patients ages 25-76 were included. Each patient received one AP radiograph and three repeated ST measurements over two months. Values were analyzed by two raters to determine comparability between ST and radiographic measurements. Interobserver reliability (ICC) was calculated and statistical significance was determined by the p-value of a paired two-tailed t-test. RESULTS: ICC showed excellent reliability (> 0.90). There was no significant difference (p > 0.40) in apical vertebral deviation/translation between conventional radiography (0.9 ± 0.8) and ST (1.2 ± 1.0). There was no significant difference (p > 0.30) in sagittal balance radiographic (4.0 ± 3.1) and ST (4.4 ± 3.3), and coronal balance radiographic (1.4 ± 1.3) and ST (1.1 ± 1.1) measurements. Significant difference (p < .001) was found between lumbar lordosis radiographic (52.6 ± 18.4) and ST (37.9 ± 16.6), kyphotic angle radiographic (35.1 ± 16.0) and ST (50.0 ± 11.9), and scoliotic angle radiographic (11.3 ± 12.4) and ST (17.7 ± 10.2) measurements. CONCLUSIONS: No significant difference was observed between various ST and radiographic measurements, including apical vertebral deviation, sagittal balance, and coronal balance. While a larger prospective study is needed to further assess the validity of ST, these initial measurements suggest the possibility of an effective and radiation-free adjunctive method of assessing balance in the coronal plane.

The "Double Washer" Technique Is an Effective Strategy for Bicortical Fixation in Periprosthetic Fractures About a Femoral Stem: A Technical Trick and Case Series.

SUMMARY: Periprosthetic fractures about the hip and knee are challenging injuries to treat for the orthopaedic surgeon. The pre-existing femoral implant and poor bone quality provide for difficulties in achieving stable fixation. We present a surgical technique and clinical series of 5 patients describing the use and outcomes of a 3.5 screw with a "double washer" technique to achieve bicortical fixation around a femoral prosthesis.

Comparing Surgical Treatments for Spondylolysis: Review on Current Research.

STUDY DESIGN: Narrative review. OBJECTIVE: To compare the various surgical methods of repairing spondylolysis defects in regard to improving pain, restoration of function, radiographic improvement, and complication rate. SUMMARY OF BACKGROUND DATA: Spondylolysis is a defect in the pars interarticularis of the vertebral arch, typically in the lumbar vertebra. Treatment can be nonoperative and/or surgical. There are various types of surgical repair including spinal compression, fusion, and direct pars repair. METHODS: A comprehensive review of the English literature was performed utilizing Medline, Embase, and Web of Science. Inclusion criteria included papers or abstracts that evaluated the surgical techniques. Exclusion criteria included non-English-language papers or abstracts with inadequate information about outcomes. RESULTS: Postoperative pain levels and patient function were consistently improved, regardless of surgical technique chosen. Positive clinical outcomes after surgery were seen more often in patients under age 20 and those who underwent minimally invasive repairs. Positive radiographic improvements were reported broadly, although some reported higher rates of nonunion with spinal compression. Complication rates were low throughout and minimally invasive techniques reported decreased blood loss and shorter hospital stays. CONCLUSIONS: Present surgical options appear largely comparable in terms of their ability to provide meaningful treatment for spondylolysis where conservative treatments have failed or otherwise remain unattempted.

Telerounding Offers High Patient Satisfaction After Total Joint Arthroplasty.

BACKGROUND: Research in surgical fields other than orthopedics has demonstrated high patient satisfaction with non-traditional telerounding modalities. QUESTIONS/PURPOSES: We sought to determine patient satisfaction and Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) scores of patients who experienced telerounding in the post-operative period after undergoing total joint arthroplasty (TJA). METHODS: Fifty consecutive TJA patients were prospectively enrolled to receive telerounding. The patients were divided into two groups based on their satisfaction with telerounding. The HCAHPS scores of the patients who received telerounding were compared with 50 control patients. RESULTS: Overall, the telerounding cohort had a positive reaction to telerounding. Comparing patients who were highly satisfied to those who were dissatisfied with telerounding, younger patients were found to be more frequently satisfied with telerounding. Compared with patients who did not receive telerounding, patients who experienced telerounding rated the hospital higher on a 10-point scale were more likely to recommend the hospital to others, more frequently believed their physicians treated them with courtesy and respect, and more often believed their physicians always listened to them carefully. CONCLUSION: An overwhelming majority of our patients found telerounding using FaceTime enhanced their care while recovering post-operatively from TJA. Those patients were typically younger and had significantly higher HCAHPS scores, which potentially can enhance the physician-patient relationship.

A Case of Titanium Pseudotumor and Systemic Toxicity After Total Hip Arthroplasty Polyethylene Failure.

We describe the case of a 57-year-old female who underwent bilateral ceramic-on-polyethylene total hip arthroplasties performed in 2015. She presented to us in 2018 with headaches, fatigue, and right hip pain 5 months after an atraumatic right polyethylene liner failure for which she did not seek treatment. She was found to have imaging consistent with an adverse local tissue reaction and massive pseudotumor formation. During revision surgery, fracture of the acetabular liner was noted, with ceramic head wear through the titanium cup. In the months after her debridement and prosthesis revision, the patient continued to complain of systemic symptoms including weakness, fatigue, headaches, and vision problems. Serum titanium levels were found to be 100 times higher than normal. This case serves as a rarely reported example of titanium toxicity and titanium pseudotumor formation in the setting of polyethylene failure.

Rapid Bodyweight Reduction before Lumbar Fusion Surgery Increased Postoperative Complications.

STUDY DESIGN: Retrospective cohort study. PURPOSE: To determine the effects of massive weight loss on perioperative complications after lumbar fusion surgery (LFS). OVERVIEW OF LITERATURE: Patients who are obese are more likely to experience low back pain, which would require LFS. Nonetheless, they have a higher risk of perioperative complication development compared with individuals who are not obese. METHODS: Patients who underwent LFS at hospitals that participated in the National Surgical Quality Improvement Program database within the United States between 2005 and 2015. Outcomes included 30-day medical complications, surgical complications, and length of stay (LOS). We analyzed a total of 39,742 patients with the use of the International Classification of Disease, ninth revision codes. The patients were categorized in the following two groups: group 1, individuals with a history of massive weight loss within 6 months before LFS, and group 2, individuals without a history of massive weight loss before surgery. Massive weight loss was defined as loss of 10% of total body weight. Patients with a history of malignancy or chronic disease were excluded from the study. Patients in each group were randomly matched based on age, gender, sex, smoking status, and body mass index. Paired two-tailed Student t-tests were used to compare the outcomes. RESULTS: Of the 39,742 patients identified, 129 (0.32%) met the criteria for inclusion in the weight loss group (WL group) and were successfully matched to individuals in the non-weight loss group (non-WL group). Compared with the non-WL group, the WL group had a significantly longer LOS (9.7 vs. 4.0 days, p<0.05), higher surgical site infections (SSIs) (8.0 vs. 3.0, p<0.05), increased number of blood transfusions (40.0 vs. 20.0, p<0.05), and greater deep vein thrombosis (DVTs) (5.0 and 0.00, p<0.05). CONCLUSIONS: On a nationwide scale, rapid weight loss before LFS is associated with a higher rate of postoperative complications, including SSI and DVTs, longer average LOS, and more frequent blood transfusions.

Nonmaleficence in medical training: Balancing patient care and efficient education.

The principle of nonmaleficence requires that every medical action be weighed against all benefits, risks, and consequences, occasionally deeming no treatment to be the best treatment. In medical education, it also applies to performing tasks appropriate to an individual's level of competence and training. Students, residents, and attending physicians alike maintain a beneficence-based responsibility to patients, and attending physicians have a fiduciary responsibility to educate younger generations of doctors.

Etiology of Adolescent Idiopathic Scoliosis: A Literature Review.

Adolescent idiopathic scoliosis (AIS) is the peripubertal development of spinal curvature of a minimum of 10°. AIS is thought to be attributable to genetic factors, nutrition, early exposure to toxins, and hormonal dysregulation. Recent literature suggests these factors may compound to determine both disease onset and severity. Currently, treatment is limited to observation, bracing, and surgical intervention. Intervention is presently determined by severity and risk of curve progression. As they emerge, new therapies may target specific etiologies of AIS.

Current advances in the treatment of medial and lateral epicondylitis.

Despite advances elucidating the causes of lateral and medial epicondylitis, the standard of care remains conservative management with NSAIDs, physical therapy, bracing, and rest. Scar tissue formation provoked by conservative management creates a tendon lacking the biomechanical properties and mechanical strength of normal tendon. The following review analyzes novel therapies to regenerate tendon and regain function in patients with epicondylitis. These treatments include PRP injection, BMAC, collagen-producing cell injection, and stem cell treatments. While these treatments are in early stages of investigation, they may warrant further consideration based on prospects of pain alleviation, function enhancement, and improved healing.

Medical optimization of lumbar fusion in the osteoporotic patient.

PURPOSE: In patients undergoing lumbar fusion, osteoporosis has been shown to lead to poorer outcomes and greater incidence of fusion-related complications. Given the undesirable effect of osteoporosis on lumbar fusion surgery, a number of medications have been proposed for use in the peri- and postoperative period to mitigate risks and enhance outcomes. The purpose of this review was to summarize and synthesize the current literature regarding medical management of osteoporosis in the context of lumbar fusion surgery. METHODS: A literature search of PubMed, Embase, and Web of Science was conducted in October 2016, using permutations of various search terms related to osteoporosis, medications, and lumbar fusion. RESULTS: Teriparatide injections may lead to faster, more successful fusion, and may reduce fusion-related complications. Bisphosphonate therapy likely does not hinder fusion outcomes and may be useful in reducing certain complications of fusion in osteoporotic patients. Calcitonin and selective estrogen receptor modulator therapy show mixed results, but more research is necessary to make a recommendation. Vitamin D deficiency is associated with poor fusion outcomes, but evidence for supplementation in patients with normal serum levels is weak. CONCLUSIONS: Overall, the current body of research appears to support the use of teriparatide therapy to enhance lumbar fusion outcomes in the osteoporotic patient, although the extent of research on this topic is limited. Additionally, very little evidence exists to cease any of the mentioned osteoporosis treatments prior to lumbar fusion.

Bone graft materials for posterolateral fusion made simple: a systematic review.

BACKGROUND: Iliac crest has long been the gold standard for lumbar fusion, but concerns over donor site morbidity have led to a wide variety of bone graft substitutes. Despite prolific research, a general consensus is yet to be reached on bone graft materials that lead to optimal fusion. PURPOSE: The purpose of this review is to evaluate the current literature for bone graft material options that maximize fusion rate in posterolateral lumbar fusion surgery. DESIGN: Systematic Review. METHODS: A PRISMA-compliant systematic review of PubMed, EMBASE, and the Web of Science was conducted. Included studies were published from January 2000 to July 2015, were clinical human research studies involving available autograft, allograft, or synthetic bone graft options in posterolateral lumbar spine fusion, and reported radiographic fusion rate as a primary end outcome. This research had no funding source and the authors have no conflicts to declare. RESULTS: 81 articles underwent full-text review, and 48 were included in this study. 18 studies assessed fusion rate by plain radiographs alone (37.5%), while 6 used CT scan (12.5%), and 24 used both (50.0%). 45 studies looked at ICBG in conjunction with LAG (29), BCP(1), APC (2), BMPs (6), or DBM (1). Aggregate mean fusion rates among these ranged from 68.0 to 91.5%. 22 studies evaluated fusion rates of LAG, either isolated (3) or combined with ceramic extenders (8), DBM (4), BMP (1), BMA (4), APC (1), or ICBG(1). Aggregate mean fusion rate ranged from 75 to 95.5%. With the exception of studies involving allograft (mean fusion rate 40.0%), the mean fusion rate for all other graft combinations exceeded 70.0%. CONCLUSIONS: While our results find that LAG+BMA provided highest fusion rate, most material options analyzed in this study provide comparable fusion outcomes. The ideal graft option must incorporate a combination of materials with osteoconductive, osteoinductive, and osteogenic properties. Our results represent the robust and dynamic nature of the current state of lumbar graft technology. These slides can be retrieved under Electronic Supplementary Material.

Utility of Supine Lateral Radiographs for Assessment of Lumbar Segmental Instability in Degenerative Lumbar Spondylolisthesis.

STUDY DESIGN: Retrospective chart review OBJECTIVE.: To determine whether supine lateral radiographs increase the amount of segmental instability visualized in single-level lumbar degenerative spondylolisthesis, when compared to traditional lateral flexion-extension radiographs. We hypothesized that supine radiographs increase the amount of segmental instability seen in single-level lumbar spondylolisthesis when compared to flexion-extension. SUMMARY OF BACKGROUND DATA: Accurate evaluation of segmental instability is critical to the management of lumbar spondylolisthesis. Standing flexion-extension lateral radiographs are routinely obtained, as it is believed to precipitate the forward-backward motion of the segment; however, recent studies with magnetic resonance imaging and computed tomography have shown that the relaxed supine position can facilitate the reduction of the anterolisthesed segment. Here, we show that inclusion of supine lateral radiographs increases the amount of segmental instability seen in single-level lumbar spondylolisthesis when compared to traditional lateral radiographs. METHODS: Supine lateral radiographs were added to the routine evaluation (standing neutral/flexion/extension lateral radiographs) of symptomatic degenerative spondylolisthesis at our institution. In this retrospective study, 59 patients were included. The amount of listhesis was measured and compared on each radiograph: standing neutral lateral ("neutral"), standing flexion lateral ("flexion"), standing extension lateral ("extension"), and supine lateral ("supine"). RESULTS: A total of 59 patients (51 women, 8 men), with a mean age of 63.0 years (±9.85 yr) were included. The mean mobility seen with flexion-extension was 5.53 ±â€Š4.11. The mean mobility seen with flexion-supine was 7.83% ±â€Š4.67%. This difference was significant in paired t test (P = 0.00133), and independent of age and body mass index. Maximal mobility was seen between flexion and supine radiographs in 37 patients, between neutral and supine radiographs in 11 cases, and between traditional flexion-extension studies in 11 cases. CONCLUSION: Supine radiograph demonstrates more reduction in anterolisthesis than the extension radiograph. Incorporation of a supine lateral radiograph in place of extension radiograph can improve our understanding of segmental mobility when evaluating degenerative spondylolisthesis. LEVEL OF EVIDENCE: 3.

Developmental dysplasia of the hip: a history of innovation.

Developmental dysplasia of the hip (DDH) is a relatively common malady that has profound consequences in the infant if left untreated. Effective and early treatment of DDH has been praised as one of the most successful ventures of modern pediatric orthopedics. Yet, before the modern management of DDH came into existence, there were extensive technological developments in the field of harnesses, casts, and traction methods. This paper aims to identify the centuries-old history of advancement in DDH treatment and the many important people involved. Their devices, thoughts, and ideas continue to have a profound impact on the current practice of orthopedic surgery.
