Study Design. Correlational study. Objective. In spine trauma patients, we aimed to assess the correlation of patient-reported outcome measurement information system (PROMIS) physical function (PF), pain interference (PI), and Depression scores with Oswestry Disability Index (ODI) and Neck Disability Index (NDI) ODI/NDI scores. Summary of Background Data. The ODI and NDI were intended as patient-reported outcome measures (PROMs) to evaluate clinical outcomes in patients seeking spine care. To date, the PROMIS has not been studied in the spine trauma population. Methods. Between January 1, 2015 and December 13, 2017, patients presenting to a single, level 1 trauma center spine clinic with known spine trauma were identified. A total of 56 patients (52 operative, 4 nonoperative) representing 181 encounters were identified. PROMIS PF, PI, and Depression, as well as the ODI or NDI, were administered to patients. Spearman rho (ρ) were calculated between PROMs. Results. A strong correlation exists between PROMIS PI and the ODI (ρ = 0.79, P < 0.001), while a strong-moderate correlation exists between PROMIS PF and the ODI (ρ = −0.61, P < 0.001). A moderate correlation exists between PROMIS Depression and the ODI (ρ = 0.54, P < 0.001). Strong correlations exist between PROMIS PI and the NDI (ρ = 0.71, P < 0.001) and PROMIS Depression and the NDI (ρ = 0.73, P < 0.001). A poor correlation exists between PROMIS PF and the NDI (ρ = −0.28, P = 0.005). Conclusion. PROMIS PF, PI, and Depression domains significantly correlate with the ODI and NDI; however, only PROMIS PI strongly correlates with both the NDI and ODI. This suggests that PROMIS PI can be used to capture similar information to that of the ODI or NDI but that PROMIS PF and Depression may offer additional clinical information. Level of Evidence: 2

Background: Chordomas are rare malignant tumors of the spinal column often afflicting the upper cervical spine and sacrum. There are few large single center series on chordomas due to its rarity. The purpose of this study is to report a single center's experience with the operative and non-operative management of chordomas. Methods: We evaluated our institution's pathology database from 1994 to 2016 to identify patients diagnosed with chordomas. Inclusion criteria were chordomas of the mobile spine and sacrum. Exclusion criteria were chordomas of the clivus and resection performed at another institution. We collected patient demographics as well as the type of resection performed, intra-operative complications, wound complications and recurrence/prognosis. Results: We identified 18 patients diagnosed with chordomas at our institution, and 12 met our inclusion criteria. There were four females and eight males with an average age of 64 [32-87] years. All patients were Caucasian and 10 of the 12 had surgery. Of the two patients with sacral chordomas that did not have surgery, one received chemotherapy and the other did not elect for any treatment. One is alive 161 months following diagnosis and the second died 96 months following diagnosis. Five of the lesions were in the mobile spine (one cervical, two thoracic, two lumbar) and seven were in the sacrum. Six patients underwent an en bloc resection [two via total en bloc spondylectomy (TES)]. Average length of follow up is 60 [3-161] months and eight of 12 patients are alive at latest follow up. Intraoperative complications included cardiac arrest, pleural tear, and excessive blood loss (8 L). Two patients, with sacral chordomas, had wound complications. Recurrence occurred in one patient with piecemeal resection and one patient with incomplete resection had postoperative metastatic lesions to the liver and lung. Conclusions: We found less recurrence in patients managed with an en bloc resection as opposed to piece meal or intralesional resections. Sacral chordoma patients had higher wound complication rates as compared to chordomas of the mobile spine. The long life expectancy of non-surgically managed patients underscores the indolent nature of chordomas.

Introduction:In an attempt to improve price transparency, the Centers for Medicare & Medicaid Services (CMS) now requires hospitals to post clear, accessible pricing data for common procedures. We aimed to determine how many top orthopaedic hospitals are compliant with the new regulation and whether there was any correlation between hospital charges and outcomes after total hip arthroplasty (THA) and total knee arthroplasty (TKA). Methods: The hospital websites of the top 101 orthopaedic hospitals per the US News & World Report 2020-2021 were explored to assess compliance with the price transparency requirement. We recorded the gross inpatient charge, cash price, payer-specific negotiated charge, and deidentified maximum and minimum payer rates for THA and TKA. Outcome metrics included hospital ranking and Medicare riskadjusted arthroplasty readmission and complication rates. Results: Although 94 hospitals (93%) posted some shoppable service information as required by CMS, only 21 hospitals (20%) were fully compliant. The mean inpatient charge for THA and TKA was $72,111

The many factors contributing to patellar instability have led to various surgical techniques that are used commonly today. When surgery is deemed necessary, the operation should be tailored to the patient's specific pathoanatomy. Patients with malalignment can often be stabilized by moving the tibial tuberosity to a more medial, anteromedial, or distal position. Subsequent changes in the forces acting on the patellofemoral joint will depend on the direction and distance of the tuberosity repositioning. When planning tuberosity osteotomies, it is crucial to understand how to use clinical and imaging modalities to measure and quantify tuberosity position accurately to achieve the desired degree of realignment.

Background: Injury to the quadriceps tendon is rare and most commonly occurs in middle-aged men. Few reports are available regarding outcomes after quadriceps tendon rupture in younger patients. Purpose/Hypothesis: To review the clinical outcomes of patients who underwent quadriceps tendon repair at age ≤40 years. We hypothesized that this cohort would experience better clinical outcomes in comparison to historical older controls. Study Design: Case series; Level of evidence, 4. Methods: Using an institutional database, we retrospectively identified patients who underwent quadriceps tendon repair between January 2009 and December 2017. Patients were included in the study if they were aged ≤40 years at the time of surgery and had sustained an isolated, complete tendon rupture. Patient and injury characteristics were recorded. Patients were contacted to complete a custom survey, the 2000 International Knee Documentation Committee (IKDC) form, the Lysholm scale, and the Tegner scale. Results: Included were 38 patients (86.8% male; mean age, 32.0 ± 6.9 years; age range, 15-40 years), with a mean follow-up of 5.9 ± 2.3 years (range, 2.4-11.3 years). At final follow-up, the mean IKDC score was 74.1 ± 22.6 (range, 26.4-100.0), and the mean Lysholm score was 85.4 ± 20.0 (range, 30-100), which were similar if not inferior to historical controls of patients >40 years. Only 16 patients (42.1%) had unchanged or higher Tegner scores after surgery, whereas 22 patients (57.9%) reported lower postoperative activity level. Overall, 91.2% (31/34) of workers returned at a mean 3.9 months after surgery, whereas 63% (12/19) of athletes were able to return to play at 8.8 months. At final follow-up, 12 patients (31.6%) reported persistent pain and stiffness in their knees. Additionally, 3 patients (7.9%) reported pain without stiffness, and 4 (10.5%) reported stiffness without pain. Patients reporting pain or stiffness had significantly lower IKDC scores, Lysholm scores, postoperative Tegner scores, and change in their Tegner score at final follow-up in comparison to those who did not report pain or stiffness. Conclusion: Although patients aged ≤40 years had satisfactory outcomes after quadriceps tendon repair, this injury resulted in significant long-term sequelae in a substantial percentage of patients, despite their youth. Further, this group did not have better outcomes compared with historical controls aged > 40 years.

Objectives: Superior labrum from anterior to posterior (SLAP) tears are increasingly common shoulder injuries in adolescent athletes who participate in repetitive overhead throwing. The purpose of this study is to evaluate adolescent baseball athletes who undergo SLAP repair in order to determine their long-term progression of play, surgical outcomes, and overall satisfaction with surgery. Methods: Patients between the ages of 10-19 who underwent a SLAP repair over a 10-year period from 2008-2018 with minimum two year follow-up were identified by a database query in the medical records of a single institution. From this cohort, non-baseball athletes and injuries to non-throwing shoulders were excluded. After identifying the cohort, patients were contacted via phone to complete functional outcome scores including Conway Score, Western Ontario Shoulder Instability (WOSI) Index, Kerlan-Jobe Orthopedic Clinic (KJOC) Shoulder and Elbow Score, Short Form 12 Mental (MCS)/Physical (PCS) survey and a custom return to play questionnaire. Results: During this time period, 59 baseball players met the inclusion criteria for this study and 76.3% (45/59) of patients were available to be contacted to complete final follow-up surveys at a minimum of 2 years. All patients were male with a mean age of 17.4 +/- 1.5 (14-19) years. The mean follow-up of this cohort was 5.3 +/- 2.6 (2.1-12.1) years. The overall return to play rate was 75.6% (34/45). The average time from surgery to initiation of throwing was 5.9 +/- 2.0 (2-12) months and the average time to return to full competition was 11.3 +/- 3.5 (6-22) months after the surgery. After the SLAP repair, those who returned to play continuing playing baseball competitively for 3.0 +/- 1.9 (0.5-8.0) years after surgery. At the time of final follow-up, 71.1% (32/45) of players had stopped playing baseball. Of those who had stopped playing competitive baseball, 12 (37.5%) reported it was because they were not recruited to the next level, 10 (31.3%) reported they lost the desire to play and 10 (31.3%) reported their shoulder prevented them from playing. The overall mean KOJC, WOSI, SF-12 MCS and SF-12 PCS scores were 60.0 +/- 27.4 (range, 0-100), 21.0+/-20.6% (0-73.8%), 55.2+/-3.9 (37.4-59.8) and 55.2+/-5.6 (range, 37.9-65.7) respectively. The overall satisfaction score was 83.2% with 86.7% (39/45) saying they given the opportunity they would undergo surgery again. Conclusions: The results of this study demonstrated a low return to play rate and low patient reported outcomes on baseball specific surveys among adolescent baseball players who underwent a SLAP repair. Mean functional outcome scores between pitchers and position players were not found to be significantly different. Based on these findings, orthopedic surgeons can better counsel their adolescent baseball players on expectations for future return to play and functional outcomes after SLAP repair.
