RESUMO
The resting zone (RZ) in mammalian growth plates is critical for maintaining and regulating chondrocyte turnover during longitudinal bone growth as a control tower and stem cell reservoir. Although recent lineage tracing studies have identified several markers for stem cells in the RZ, these markers only partially label chondrocytes in the RZ, suggesting that the resting chondrocytes (RCs) are a heterogeneous population with different types of stem cells. Since a comprehensive marker for RCs is still lacking, the RZ is generally determined based on ambiguous histological criteria, such as small and round chondrocytes without columnar formation, which may lead to inconsistencies among researchers. Therefore, in this study, we used single-cell RNA sequencing (scRNAseq) of growth plate chondrocytes followed by validation by fluorescence in situ hybridization (FISH) to precisely annotate cell clusters in scRNAseq and search for a marker of RCs. The scRNAseq analysis revealed that apolipoprotein E (Apoe) was the top-hit gene, which was ubiquitously expressed in the RC cluster. FISH confirmed that Apoe was exclusively localized to the histologically defined RZ. In newly generated Apoe-mCherry knock-in mice, we further confirmed that mCherry expression mirrored the distribution of Apoe-expressing chondrocytes in the RZ particularly after the formation of the secondary ossification center. These mCherry+ RCs were slow cycling in vivo and exhibited stem cell properties both in vitro and in vivo. Moreover, APOE was detected in human growth plate RCs. These findings suggest that Apoe is a novel pan-RC marker in both mouse and human growth plates.
RESUMO
BACKGROUND: While radial bow shape is well characterized in adults, its development in children is not well understood. Previous studies on the radial bow use radiographs, thus, rotational positioning of the forearm could alter bowing measurements. This study used 3D imaging to better assess the pediatric radial bow. METHODS: Computed tomography scans from the New Mexico Decedent Image Database were obtained for ages 2 to 16 (females) and 18 (males) (n=152). 3D models were generated using Slicer and Rhino software. Length of the entire radial bow (bicipital tuberosity to sigmoid notch), maximum radial bow, location of the maximum radial bow (bicipital tuberosity to the point of maximum bowing), and distal, middle, and proximal third radial bows were measured. RESULTS: The length of the entire bow increased with age, with a strong correlation with age ( r =0.90, P <0.01). The maximum bow increased with age, with a strong correlation with age ( r =0.78, P <0.01). The maximum bow normalized to the length of the entire bow increased mildly with age, mean 0.059 ± 0.012 ( r =0.24, P =0.0024), but seems to plateau around age 8. The location of the maximum bow increased with age ( r =0.85, P <0.01). The normalized location of the maximum bow remained constant between ages, with a mean of 0.41 ± 0.10 ( r =0.12, P =0.14). The normalized distal third bow mildly increased with age ( r =0.34, P <0.01), the normalized middle third bow mildly increased with age ( r =0.25, P <0.01), and the normalized proximal third bow remained constant between ages ( r =0.096, P =0.24). CONCLUSIONS: Normalized values for maximum, distal third, and middle third radial bow increase with age, while normalized values for location and proximal third radial bow remain relatively constant, suggesting the proportional shape of the radius changes during development, although qualitatively plateaus after age 8. LEVEL OF EVIDENCE: Retrospective comparative study, Level-III.

The care of children with primary surgical diagnoses in acute care units often involves a shared surgical and medical model ("comanagement"). There are no formal guidelines for how such programs should be structured or care provided. We used a modified Delphi process, including national experts in pediatrics and pediatric medical subspecialties, pediatric surgical specialties, and pediatric anesthesiology, to develop recommendations for best practices for comanagement programs in community and tertiary care settings.

Metacarpal fractures are among the most common hand fractures. To properly manage these injuries, surgeons must understand the anatomy, biomechanics, clinical assessment, surgical and nonsurgical treatment options, and potential complications. Metacarpal head fractures often require surgical treatment to restore the joint surface by using a variety of techniques. Metacarpal neck fractures are usually stable injuries that do not require surgical intervention, but surgeons must know when surgical intervention is indicated. Fractures of the metacarpal shaft can be treated surgically and nonsurgically and may be associated with large bone defects or soft-tissue injuries that require careful consideration. Finally, fractures involving the carpometacarpal joints must be promptly managed to avoid long-term complications, potentially requiring salvage procedures.

Multiple fracture patterns can occur around the proximal interphalangeal joint and require surgeons to have a thorough understanding of the anatomy, clinical and radiographic examination, common fracture patterns, surgical and nonsurgical treatment options, and potential complications. Proximal phalangeal condylar fractures are typically managed surgically, because even nondisplaced fractures have a propensity for displacement. Middle phalangeal base fractures most commonly present as a volar lip fracture with or without dorsal subluxation or dislocation. Treatment options include extension block splinting or pinning, transarticular pinning, open reduction and internal fixation, external fixation, volar plate arthroplasty, and hemihamate arthroplasty. Less common fractures include dorsal lip fractures with or without volar subluxation or dislocation (the central slip fracture), lateral plateau impaction or avulsion injuries, and pilon fractures. The main goals in the management of middle phalangeal base fractures are to restore articular congruency and initial early range of motion, which are more important than obtaining an anatomic reduction.

Transphyseal fractures of the distal humerus often occur in children younger than 4 years as a result of birth trauma, nonaccidental trauma, or falls from a low height. It is important to identify and treat these injuries in a timely manner to ensure successful management. Most transphyseal fractures of the distal humerus are treated with closed reduction and percutaneous pinning with the aid of an elbow arthrogram. The most common complication following a fracture is cubitus varus caused by growth arrest, malunion, or osteonecrosis of the medial condyle. Normal carrying angles may be restored through corrective lateral closing wedge osteotomy.

Phalangeal fractures are extremely common in the pediatric and adolescent populations. The incidence of phalangeal fractures peaks in children ages 10 to 14 years, corresponding to the age in which children begin contact sports. Younger children are more likely to experience crush injuries, whereas older children often sustain phalangeal fractures during sports. The physis is particularly susceptible to fracture because of the biomechanically weak nature of the physis compared with the surrounding ligaments and bone. Phalangeal fractures are identified through a thorough physical examination and are subsequently confirmed with radiographic evaluation. Management of pediatric phalangeal fractures is dependent on the age of the child, the severity of the injury, and the degree of fracture displacement. Nondisplaced fractures are often managed nonsurgically with immobilization, whereas unstable, displaced fractures may require surgery, which is often a closed rather than open reduction and percutaneous pinning.

BACKGROUND: Obstetric brachial plexus injuries (OBPI) can have mental health implications on parents coping with this injury to their newborn. The purpose of this study was to assess the mental health of mothers with newborns with an OBPI and identify resources that can help screen and treat mental health needs. MATERIAL AND METHODS: Three groups of mothers were prospectively given a self-reported survey: 1) Newborns with OBPI; 2) Newborns in the nursery without OBPI; 3) Newborns in the neonatal intensive care unit (NICU). The survey consisted of demographic questions, the PHQ-9 and PCL-S screening tools, and parents' exposure to community violence, family support and use of drugs or alcohol. RESULTS: Fifty-seven mothers were prospectively enrolled, and 30% (17/57) of mothers screened in for post-traumatic stress disorder (PTSD). OBPI mothers had significantly higher rates of PTSD symptoms when compared to mothers of children in the full-term nursery (difference = 36.4%; p < 0.01). No statistically significant difference was found between groups regarding depression symptoms. CONCLUSIONS: OBPI can be very difficult to cope with for parents and family members. Forty-two percent of mothers with newborns with OBPI or children in the NICU screened in for PTSD symptoms. OBPI clinics should be staffed similarly to the NICU with clinical social workers to appropriately screen and treat parents with PTSD and depression symptoms.

BACKGROUND: Transphyseal humeral separations (TPHS) are rare injuries often associated with non-accidental trauma, necessitating accurate diagnosis. This study aims to assess the accuracy of diagnosis of TPHS. METHODS: A retrospective review was conducted at five academic pediatric institutions to identify all surgically treated TPHS in patients up to 4 years of age over a 25-year period. Demographics, misdiagnosis rates, and reported misdiagnoses were noted. Comparative analyses were performed to analyze the effects of patient age and injury mechanism on misdiagnosis rates. RESULTS: Seventy-nine patients (average age: 17.4 months) were identified, with injury mechanisms including accidental trauma (n = 49), non-accidental trauma (n = 21), Cesarean-section (n = 6), and vaginal delivery (n = 3). Neither age nor injury mechanism were significantly associated with diagnostic accuracy in the emergency department (ED)/consulting physician group. ED/consulting physicians achieved an accurate diagnosis 46.7% of the time, while radiologists achieved an accurate diagnosis 26.7% of the time. Diagnostic accuracy did not correlate with Child Protective Services (CPS) involvement or with a delay in surgery of more than 24 h. However, a significant correlation (p = 0.03) was observed between injury mechanism and misdiagnosis rates. CONCLUSION: This multicenter analysis is the largest study assessing TPHS misdiagnosis rates, highlighting the need for raising awareness and considering advanced imaging or orthopedic consultation for accurate diagnosis. This also reminds orthopedic surgeons to always have vigilant assessment in treating pediatric elbow injuries. LEVEL OF EVIDENCE: Level III-Retrospective Cohort Study.
RESUMO
BACKGROUND: In the lower extremity, studies have suggested an optimal nail diameter to medullary canal diameter (ND/MCD) ratio to minimize postoperative complications. The goal of this study was to determine whether a correlation exists between the occurrence of complications, angulation, and range of motion and the ratio of the ND/MCD in the upper extremity. METHODS: A total of 85 radius and ulna fractures treated with flexible intramedullary nails had ND/MCD ratios measured. Random-effects models were developed to determine the association between complications and ND/MCD ratio, angulation and ND/MCD ratio, and range of motion and ND/MCD ratio. The results were reported for unadjusted models and adjusted models. RESULTS: Of the 85 forearm fractures treated with intramedullary nailing, there were 3 complications. The average follow-up was 6 months. The ND/MCD ratios were categorized as <0.50, 0.50 to 0.59, and ≥0.60. There was not a significant association between the different ratios and angulation, or risk of complication. There was an association between the ND/MCD ratio ≥0.60 and decreased pronation of -1.58° (-2.77° to -0.38°) and supination of -2.68° (-4.91° to -0.46°) (P < .05). CONCLUSION: This study found that there was not an association between the nail to canal diameter ratio and postoperative angulation in forearm fractures treated with flexible intramedullary nails. When choosing a flexible nail for forearm fractures, there does not appear to be an optimal ratio; it is therefore reasonable to use the ND that passes more easily.
RESUMO
BACKGROUND: Widening of the scapholunate (SL) interval greater than 2 mm is diagnostic of an injury in adults; however, this absolute number cannot be used for skeletally immature individuals due to the ossification of the carpal bones. The purpose of this study was to determine age-appropriate normative values for the radiographic SL interval in the skeletally immature population. METHODS: Normal pediatric wrist radiographs were identified. The radiographic SL interval was measured as the distance between the scaphoid and the lunate at the mid-joint space between the scaphoid and the lunate, and the SL and capitolunate angles were measured on lateral views. An initial inter-rater reliability assessment was completed with strong inter-rater reliability. RESULTS: In all, 529 radiographic series of children (276 male), aged 4 to 17 years, were reviewed. A negative linear correlation between chronological age and distance at the mid-joint space was observed. The average values for the radiographic SL interval ranged from 9.07 to 1.57 mm. The average SL and capitolunate angles were 52.0° and 10.6°, respectively. No linear relationship was found between chronological age and SL or capitolunate angle (R = 0.07 and 0.03, respectively). CONCLUSIONS: The visible radiographic distance between the scaphoid and the lunate decreases with increasing age as the carpal bones ossify. The normative values defined in this study can be used to determine whether a true widening of the SL interval is present in the pediatric population. No linear relationship exists between chronological age and SL or capitolunate angle.
RESUMO
BACKGROUND: Extensor carpi ulnaris (ECU) tendinopathy is characterized by pain along the dorsal and ulnar aspect of the wrist and distal forearm. It is common in athletes who play stick and racquet sports due to repetitive motion and axial-loading through the wrist and forearm. Conservative therapeutic options include rest, the use of anti-inflammatory medications, and various injections. Rehabilitation via occupational or physical therapy includes therapeutic exercise, splinting, activity modification, manual therapy, and modalities. METHODS: A narrative review of the literature on ECU tendinopathy is presented, and a case study approach is used to highlight the clinical management of this condition in an elite athlete. RESULTS: An approach of medical management and rehabilitation allowed this patient to successfully return to play. CONCLUSIONS: A combination of conservative measures and rehabilitation can be used to treat ECU tendinopathy and permit patients to be symptom-free and return to their desired activities.
RESUMO
PURPOSE: The treatment of ganglion cysts of the wrist remains understudied in the pediatric population, with the literature showing variable recurrence rates following different interventions. This study sought to determine whether surgical and nonsurgical management of pediatric ganglion cysts was associated with improved resolution rates when compared to observation alone. METHODS: We identified 654 cases of pediatric ganglion cysts treated across 5 institutions between 2012 and 2017. The mean age at presentation was 11.6 ± 5.2 years. Of the patients, 315 had >2 years (mean, 50.0 months) of follow-up, either via chart review or telephone callbacks. There were 4 different treatment groups: (1) observation, (2) cyst aspiration, (3) removable orthosis, and (4) surgical excision. RESULTS: For patients followed >2 years, the cyst resolved in 44% (72/163) of those observed. Only 18% (9/49) of those treated with aspiration resolved, and 55% (12/22) of those treated with an orthosis resolved. Surgical excision was associated with resolution of the cyst in 73% (59/81) of patients. Observation had higher rates of resolution compared to aspiration. Orthosis fabrication and observation had similar rates of cyst resolution. Surgery had the highest rates of resolution when compared to observation and aspiration. Patients older than 10 years were less likely to have the cyst resolve with observation (35%; 28/80) than those younger than 10 years (53%; 44/83) at >2 years of follow-up. CONCLUSIONS: This study did not find evidence that nonsurgical treatments were associated with improved rates of cyst resolution compared to observation alone in a large pediatric sample. Surgical excision had the overall highest rate of resolution. Despite the costs and increased clinic time of orthosis fabrication and aspiration, these treatments were not associated with improved rates of cyst resolution in pediatric ganglion cysts compared to observation, with aspiration having higher rates of recurrence compared to observation. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

IMPORTANCE: Telerehabilitation provides people with spinal cord injury (SCI) an alternative mode of accessing specialized health care. Further research on occupational therapy practitioners' perspectives of telerehabilitation may provide additional evidence for clinical practice implementation. OBJECTIVE: To explore urban occupational therapists' perspectives on the benefits of and barriers to telerehabilitation use with SCI. DESIGN: A qualitative study design using a demographic questionnaire and a single, individual semistructured interview. Thematic analyses included member checking, constant comparative analysis, triangulation, and self-description and self-reflexivity. SETTING: Residential and community settings. PARTICIPANTS: Six occupational therapists with a range of experience in SCI rehabilitation were recruited using purposeful sampling. RESULTS: Six participants were interviewed, and four primary themes emerged: (1) communication, (2) personal factors, (3) benefits, and (4) barriers. CONCLUSIONS AND RELEVANCE: Telerehabilitation offers numerous potential benefits for SCI intervention. This study provides an understanding of practitioner concerns and potential barriers to use. The results indicate that a hybrid model incorporating both in-person and distance-based treatment is likely optimal. What This Article Adds: Our results provide information that addresses practitioner concerns and recommendations for the use of telerehabilitation with people with SCI. As practitioner concerns are identified and addressed, telerehabilitation may increase in the U.S. health care system, potentially facilitating an alternative treatment delivery method for underserved populations.

Background: Preoperative antibiotics may not be necessary, given the very low infection rates associated with percutaneous pinning (PP) procedures of the upper extremity (UE). The purpose of this study was to determine the patterns and variation surrounding the use of preoperative antibiotics when performing PP procedures of the child's UE. Methods: A survey was sent to all members of Pediatric Orthopedic Society of North America to assess the use and opinions regarding preoperative antibiotics for PP procedures of the UE. Queries included the surgeon's current practice and thoughts regarding the need for preoperative antibiotics based on the anatomical location of the procedure. Results: Eight-one percent of the 295 respondents routinely order preoperative antibiotics for all PP procedures of the UE; however, only 60% felt that all patients must receive preoperative antibiotics. The requirement for preoperative antibiotics varied based on the anatomical location-81% for shoulder, 70% for elbow, 66% for wrist, and 62% for hand/finger. Canadian surgeons were significantly less likely to believe that preoperative antibiotics must be used in all UE cases, all shoulder cases, and all elbow cases (all Ps = .04). Conclusion: The vast majority (81%) of surgeons surveyed routinely prescribe antibiotics for PP procedures of the UE despite the fact that 40% of surgeons felt that antibiotics were not necessary for all procedures. As the PP procedure is performed more distally on the UE, fewer surgeons feel preoperative antibiotics are necessary. Future studies assessing infection rates with and without the use of preoperative antibiotics are necessary to determine the true need for these medications.

Background: Tendon transfers are commonly performed in patients with brachial plexus birth palsy (BPBP) to improve function. Transferring 2 tendons in patients with C5-7 injury has the potential complication of loss of midline function. The purpose of this study was to investigate whether a single tendon transfer (1TT) as opposed to the traditional double tendon transfer (2TT) resulted in any differences in functional outcomes in patients with C5-7 BPBP. Methods: A retrospective review of all patients with C5-7 BPBP who underwent tendon transfers to improve shoulder external rotation over a 5-year period was performed at 2 institutions. Outcomes were assessed using the modified Mallet (MM) classification scores. Results: Twenty-two C5-7 patients had complete records of preoperative and postoperative MM scores, including 11 sex-matched patients in both the 1TT and 2TT groups. When comparing preoperative and postoperative MM categories, there were significant improvements in both the 1TT and 2TT groups for global abduction (P < .05 and P < .01, respectively) and external rotation (P < .00001 for both). Modified Mallet (MM) hand to neck scores were significantly improved in the 2TT group (P < .05) but not in the 1TT group (P = .053). Internal rotation scores significantly decreased in both groups (P < .001). Both groups demonstrated significant increases in total scores from the preoperative MM scores (P < .01). Conclusion: The 1TT and 2TT procedures result in substantial gains in upper extremity functions for patients with C5-7 BPBP as measured by the MM score, specifically within the global abduction and external rotation subcategories. However, a significant loss occurs in internal rotation for both groups.

INTRODUCTION: Despite increased research on opioids in the orthopaedic literature, little is known of the prescribing practices of orthopaedic providers based on their level of training. The purpose of this study was to describe the discharge opioid prescribing patterns of orthopaedic providers, stratifying by level of training and orthopaedic subspecialty, within a single medical system. METHODS: A retrospective review of orthopaedic surgical encounters was performed over a 1-year period for adults who received a discharge opioid prescription. Patient demographics and prescriber characteristics were collected, including the provider's level of training (attending, fellow, resident, physician assistant [PA], and nurse practitioner [NP]) and surgical subspecialty. Junior residents were postgraduate year 1 to 3, whereas senior residents/fellows were postgraduate year 4 to 6. Discharge opioids were converted to milligram morphine equivalents (MMEs). Overprescribing was defined as a prescribing more than a seven-day supply or >45 MMEs per day. Multivariable linear regression analysis determined the factors associated with discharge MMEs, whereas logistic regression determined the factors associated with overprescribing opioids. RESULTS: Of the 3,786 patients reviewed, 1,500 met the criteria for inclusion in the study. The greatest proportion of opioid prescriptions was written by junior residents (33.9%), followed by NPs (30.1%), PAs (24.1%), senior residents/fellows (10.6%), and attendings (1.2%). Compared with junior residents, senior residents prescribed -59.4 MMEs, NPs prescribed +104 MMEs, and attendings prescribed +168 MMEs (P < 0.05), whereas PAs prescribed similar amounts (P > 0.05). Orthopaedic subspecialty was also predictive of discharge MMEs (P < 0.05). Senior residents and attendings were more likely to prescribe more than seven days of opioids (P < 0.05), whereas NPs and PAs were more likely to prescribe >45 MMEs per day (P < 0.05). DISCUSSION: This study demonstrates significant variability in opioid prescribing practices according to provider level of training and subspecialty. National guidelines for opioid prescribing practices and educational programs may help reduce such variability. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

BACKGROUND: The purpose of this study was to evaluate radiographic-based classification systems for osteochondritis dissecans (OCD) of the capitellum and determine their agreement with intraoperative findings. METHODS: Using PRISMA guidelines, we analyzed 44 studies utilizing a total of 19 classification systems. RESULTS: Magnetic resonance imaging (MRI)-based systems showed better predictive value of intraoperative staging, and the Itsubo and Kohyama classifications showed best predictive value for lesion stability. CONCLUSIONS: No classification system effectively correlated with intraoperative findings. A combination of radiograph, MRI, and computed tomography will most accurately determine OCD lesion stability. LEVEL OF EVIDENCE: IV, Systematic Review.
RESUMO
INTRODUCTION: We sought to determine whether patient and surgical factors are associated with the Press Ganey Ambulatory Surgery Survey (PGAS) satisfaction scores in patients undergoing outpatient upper extremity procedures. METHODS: A retrospective review of a single academic urban hospital's Press Ganey database was performed for patients undergoing upper extremity procedures. PGAS scores above an a priori threshold were considered satisfied. Logistic regression analyses for the PGAS Total and Provider Scores were performed to determine the predictors of patient satisfaction. RESULTS: Of the 198 patients included, the mean age was 49.6 ± 17.1 years and 55% were men. For the Total Score, multivariable analysis showed significantly less satisfaction with continuous catheter peripheral brachial plexus nerve blocks (CC-PNBs) (odds ratio [OR], 0.37; P = 0.008) and internet surveys (OR, 0.39; P = 0.007), but smokers had surprisingly more satisfaction (OR, 4.90; P = 0.016). For the Provider Score, a multivariable analysis showed less satisfaction with CC-PNBs (OR, 0.45; P = 0.035), internet surveys (OR, 0.46; P = 0.026), and geographic location (OR, 0.40; P = 0.005). Preoperative Patient-Reported Outcomes Measurement Information System scores were not associated with the PGAS scores. DISCUSSION: Factors influencing satisfaction in patients undergoing upper extremity procedures may be modifiable (CC-PNBs and survey administration method) or nonmodifiable (geographic location) and may influence future reimbursement.
