RESUMO
PURPOSE: Arthrogryposis multiplex congenita (AMC) consists of more than 400 conditions involving severe joint contractures of at least two or more body regions. Management of clubfoot in patients with AMC is notoriously challenging, with a higher likelihood of recurrence than idiopathic clubfoot, which can be treated using the Ponseti technique to avoid or delay more invasive procedures. The purpose of this study is to determine the utility of multiple serial casting as a treatment of clubfoot in AMC using Pirani scores as an objective measure of deformity. METHODS: Pirani scores were retrospectively collected from 17 AMC patients with a total of 30 clubfeet and two years follow-up from initiation of treatment. Patients with a minimum of three casting series were included. Pre-treatment and post-treatment deformity scores were examined across casting series using analysis of variance (ANOVA) statistical analysis. RESULTS: The first series pre-treatment Pirani score improved from 4.80±1.54 to 1.68±1.48 (p<0.001). The second series improved from 4.23±1.03 to 2.72±0.916 (p<0.001). The third series had the smallest improvement from 3.87±1.07 to 2.82±1.02 (p<0.001). Change in Pirani scores showed a significant decrease from the first series to the second (p=0.001) and third (p<0.001). In addition, the number of casting days was found to significantly affect the change in scores during the third series (p=0.038). CONCLUSIONS: The Ponseti technique can improve clubfoot in AMC as measured by the Pirani score. Data shows that early intervention yields better results, with a diminished yet effective ability to elicit change over time.
RESUMO
The development of new technologies and an enhanced understanding of the three-dimensional deformity in adolescent idiopathic scoliosis has led to advances in surgical management of adolescent idiopathic scoliosis. Posterior spinal approaches with pedicle screw constructs are now standard of care because they allow for powerful rotation maneuvers with three-column deformity correction. Selective fusion of the main curve while allowing for spontaneous correction of compensatory curves should be attempted whenever possible in the interest of limiting fusion size and preserving spinal mobility. Recent research provides updated criteria to determine optimal candidates for selective fusion. These criteria must be weighed against patient goals and patient-specific factors to limit complications and maximize chances of successful deformity correction.

Background: Orthopaedic surgeons rely on visual and tactile cues to guide performance in the operating room (OR). However, there is very little data on how sound changes during orthopaedic procedures and how surgeons incorporate audio feedback to guide performance. This study attempts to define meaningful changes in sound during vital aspects of total hip arthroplasty (THA) within the spectrum of human hearing. Methods: 84 audio recordings were obtained during primary elective THA procedures during sawing of the femoral neck, reaming of the acetabulum, acetabular cup impaction, polyethylene liner impaction, femoral broaching, planning of the femoral calcar and press-fit of a porous-coated stem in 14 patients. We graphed changes in frequency intensity across the human spectrum of hearing and sampled frequencies showing differences over time for statistically meaningful changes. Results: Sawing of the femoral neck, polyethylene impaction, and stem insertion showed significant temporal increases in overall sound intensity. Calcar planing showed a significant decrease in sound intensity. Moreover, spectrographic analysis showed that, for each of the critical tasks in THA, there were characteristic frequencies that showed maximal changes in loudness. These changes were above the 1 dB change in intensity required for detection by the human ear. Conclusion: Our results clearly demonstrate reproducible sound changes during total hip arthroplasty that are detectable by the human ear. Surgeons can incorporate sound as a valuable source of feedback while performing total hip arthroplasty to guide optimal performance in the OR. These findings can be extrapolated to other orthopaedic procedures that produce characteristic changes in sound. Moreover, it emphasizes the importance of limiting ambient noise in the OR that might make sound changes hard to distinguish.
RESUMO
CASE: Medial collateral ligament (MCL) injuries after total knee arthroplasty (TKA) are a rare occurrence. Traditional treatment options include repair and revision to a constrained prosthesis. We present a case of an 80-year-old man who opted for MCL reconstruction in the setting of previous TKA due to late MCL injury from a skiing accident. The presentation, operative techniques, and outcomes of this treatment option are presented. CONCLUSIONS: MCL reconstruction in the setting of TKA can lead to a successful and satisfactory outcome without the need for revision TKA.

Introduction Heterotopic ossification (HO) can be a potentially serious and devastating complication following traumatic injury to the elbow. HO prophylaxis options include nonsteroidal anti-inflammatory drugs (NSAIDs) and radiation therapy (RT) but neither has been proven more effective. The purpose of this review is to compare effectiveness and outcomes between NSAID and RT prophylaxis for HO about the elbow following a traumatic injury. Materials and Methods We performed a systematic review of PubMed and Cochrane Library for cases of HO prophylaxis following elbow trauma utilizing PRISMA guidelines to determine the most effective form of prophylaxis. Outcomes of interest included recurrence of HO, range of motion (ROM), and Mayo elbow performance index (MEPI). A total of 36 articles and 826 elbows of which 203 received RT and 623 received NSAID were identified and included in the final analysis. Results Rates of HO formation or recurrence following elbow trauma were similar between radiation and NSAID prophylaxis (15.6% vs. 22.2%, respectively p = 0.457). ROM was similar in flexion and extension arc (109.0 degrees in radiation vs. 112.8 in NSAIDs, p = 0.459) and in pronation and supination arc (118.9 degrees radiation vs. 134.7 degrees NSAIDs, p = 0.322). MEPI scores were 79.19 in the radiation group and 88.82 in the NSAIDs group at the final follow-up. Conclusion There is no statistical difference in HO development, recurrence, or final ROM between NSAIDs and RT prophylaxis following trauma to the elbow. We recommend the choice of modality based on patient characteristics, cost, and surgeon preference. Level of Evidence Level III.
RESUMO
BACKGROUND CONTEXT: The majority of patients with preoperative upper extremity weakness show improvements in motor function after anterior cervical discectomy and fusion (ACDF). Although numerous studies have examined both the extent and time course to which motor function can be expected to improve, few have shown that these improvements in motor function translate to improved health related quality of life (HRQOL) outcomes. PURPOSE: The purpose of this study was to examine the effect of preoperative weakness and duration of symptoms on HRQOL outcomes in patients who underwent ACDF. STUDY DESIGN: Retrospective cohort study. PATIENT SAMPLE: Adult patients who underwent an ACDF procedure at an academic hospital from January 2015 to December 2016 by a fellowship-trained spine surgeon. OUTCOME MEASURES: The primary outcomes of interest were HRQOL outcomes: Short Form-12 Physical/Mental Component Scores (SF-12 PCS/MCS), Neck Disability Index (NDI), and Visual Analog Scale Arm/Neck scores (VAS Arm/Neck). METHODS: Patient demographics, surgical case characteristics, and motor strength exams were collected in patients who underwent ACDF over a 2-year period. Preoperative weakness was defined by a strength grade ≤3 (on a scale from 0 to 5) in at least one upper extremity muscle group. Multivariate linear regression analysis was performed to determine the effect of the preoperative weakness on HRQOL outcomes. RESULTS: Of the 276 patients identified, 45 (16.3%) showed evidence of preoperative weakness, 44 (97.8%) of which showed subsequent postoperative motor improvements after ACDF. All patients reported significant improvements in all HRQOL outcome measures. Patients with preoperative weakness reported significantly worse preoperative VAS Arm (6.9 vs. 5.2; p=.01) and VAS Neck (6.1 vs. 4.8; p=.02) pain scores. Compared with patients without preoperative weakness, those with preoperative weakness reported significantly more improvement in NDI (ß: -10.9; p=.001). Patients with symptoms greater than or equal to 12 months and preoperative weakness showed significantly less improvement in NDI (ß: 14.8; p=.03). CONCLUSIONS: Patients with preoperative weakness generally exhibited worse pain and HRQOL measures preoperatively, and showed greater potential for improvement after ACDF. Patients with a shorter duration of preoperative weakness had greater potential for improvement in HRQOL measures after ACDF compared with those with longer duration of symptoms. ACDF is an effective procedure to improve strength and HRQOL measures across all patient groups under appropriate indications.

PURPOSE: Telehealth is a care delivery model that promises to increase the flexibility and reach of health services. Our objective is to describe patient experiences with video visits performed with their established primary care clinicians. METHODS: We constructed semistructured, in-depth qualitative interviews with adult patients following video visits with their primary care clinicians at a single academic medical center. Data were analyzed with a content analysis approach. RESULTS: Of 32 eligible patients, 19 were successfully interviewed. All patients reported overall satisfaction with video visits, with the majority interested in continuing to use video visits as an alternative to in-person visits. The primary benefits cited were convenience and decreased costs. Some patients felt more comfortable with video visits than office visits and expressed a preference for receiving future serious news via video visit, because they could be in their own supportive environment. Primary concerns with video visits were privacy, including the potential for work colleagues to overhear conversations, and questions about the ability of the clinician to perform an adequate physical examination. CONCLUSIONS: Primary care video visits are acceptable in a variety of situations. Patients identified convenience, efficiency, communication, privacy, and comfort as domains that are potentially important to consider when assessing video visits vs in-person encounters. Future studies should explore which patients and conditions are best suited for video visits.
