Long-Term Clinical Outcomes Following Nonsurgical Management of Salter-Harris Type II Fractures of the Proximal Phalanx of the Small Finger: A Prospective Cohort Study.

PURPOSE: Juxta-physeal fractures at the base of the proximal phalanx (FBPP) of the small finger are one of the most common hand fractures in children. Although many of these fractures are treated nonsurgically, it is unclear which fractures benefit from surgery or the degree of acceptable angulation appropriate for nonsurgical management. Our study aimed to assess long-term, patient-reported outcomes regarding function, appearance, and pain after nonsurgical management of FBPP of the small finger in a pediatric population. METHODS: Our hospital Picture Archiving and Communication Systems database was queried to identify radiographs of the small finger of children between the ages of 8 and 16 years old taken from 2011 to 2021. Displacement on initial injury radiographs was calculated using the diaphyseal-metacarpal head angle. Patient-reported function, appearance, and pain were measured using standardized assessment tools sent to patients and parents electronically. Optional clinical photographs were uploaded by parents and assessed for residual clinical deformity. RESULTS: One hundred eighty-one eligible subjects were identified. Eighty (44%) agreed to participate, and 40 (22%) parent and 38 patient surveys were completed. The mean age at the time of injury was 11 years old (8-14 years), and the mean age at the time of survey completion was 17 years old (11-23 years). Patient T-scores were higher than the average reference T-score on the Patient-Reported Outcomes Measurement Information System Short Form v2.0-Upper Extremity. Overall, greater than 78% of patients and parents reported appearance as 8/10 or above on a VAS. Ninety-five percent (108/114) of patients reported no pain (0/10) for pain during activities and at rest. CONCLUSIONS: Children with up to 26° of initial coronal plane angulation reported better function than a reference population, good appearance, and no pain, at a mean of 6 years after injury. Our findings support nonsurgical management of most FBPP of the small finger in children. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Radiographic Features of the Metacarpal in Blauth Type III Thumb Hypoplasia.

PURPOSE: The purpose of this study was to investigate whether radiographs can be used to aid in the determination of Blauth IIIA and IIIB thumbs. METHODS: Six pediatric hand surgeons were asked to evaluate the radiographs of 77 thumbs and classify the thumb as IIIA or IIIB and indicate which morphologic features influenced their decision. Quantitative measurements and ratios of radiographs were obtained and compared between IIIA and IIIB thumbs. RESULTS: The radiographic features selected for type IIIA thumbs include near-normal length and near-normal width and for type IIIB thumbs, abnormally short, tapered proximal end, and round proximal end. The six surveyed surgeons reached consensus in 82% (63/77) of thumbs, and this matched the enrolling surgeon's classification in 77% (59/77) cases. The ratio of the length of the thumb metacarpal compared with the length of the index metacarpal was different between IIIA and IIIB thumbs (66% ± 0.08% and 46% ± 0.18%, respectively). The ratio of the width of the thumb metacarpal shaft at its narrowest aspect to the width of the thumb metacarpal base was notably different between IIIA and IIIB (68% ± 0.13% and 95% ± 0.28%, respectively). CONCLUSIONS: Near-normal length and near-normal width of the metacarpal were used to predict IIIA and abnormally short, abnormally narrow, and a round or tapered base of the metacarpal were used to predict IIIB classification. The length of the thumb metacarpal relative to the index metacarpal is on average 66% of the length of the index metacarpal in IIIA thumbs compared with 46% in IIIB thumbs. The width of the shaft of the thumb metacarpal at its narrowest is 68% of the width of the thumb metacarpal base in IIIA thumbs, indicating a flared base. In IIIB thumbs, the shaft width was on average 95% of the base width, indicating a tapered base. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic level III.

An Analysis of Associated Conditions and the Relationship Between the Severity of Hand Manifestations With That of the Forearm in Ulnar Longitudinal Deficiency.

PURPOSE: A deeper investigation of medical and musculoskeletal conditions in patients with ulnar longitudinal deficiency (ULD) is needed. The association between the severity of the manifestations of ULD in the hands and forearms has not been firmly established. The purpose of this study was to describe the medical and musculoskeletal conditions associated with ULD and examine the relationship between hand and forearm anomalies. METHODS: The Congenital Upper Limb Differences registry was queried for all patients with a diagnosis of ULD, as defined by the Oberg-Manske-Tonkin classification system, between 2014 and 2020. The patients' demographic information, medical and musculoskeletal comorbidities, radiographs, and clinical images were reviewed. The participants were classified using the Bayne, Cole and Manske, and Ogino classification systems. RESULTS: Of 2,821 patients from the Congenital Upper Limb Differences registry, 75 patients (2.7%) with ULD (14 bilateral), with 89 affected extremities, were included. Hand anomalies were present in 93% of the patients. Approximately 19% of the patients had an associated medical comorbidity, and 20% of the patients had an associated musculoskeletal condition. Cardiac anomalies were present in 8.0% of the patients, and 12% of the patients had a lower extremity abnormality. Radial head dislocation was observed in 13 of 18 patients with Bayne type II or III ULD compared with 8 of 43 patients with other types of unilateral ULD. There was a significant positive association among the Bayne and Ogino, Bayne and Cole/Manske, and Ogino and Cole/Manske classification systems in patients with unilateral ULD. CONCLUSIONS: Associated medical and musculoskeletal conditions are common in patients with ULD, of which cardiac and lower extremity abnormalities are most frequently observed. There is a significant positive association between the severity of forearm anomalies and that of hand anomalies in patients with unilateral ULD. All patients with ULD should undergo a thorough cardiac evaluation by their pediatrician or a pediatric cardiologist. TYPE OF STUDY/LEVEL OF EVIDENCE: Symptom prevalence study III.

Complications in the 2-Year Postoperative Period Following Pediatric Syndactyly Release.

PURPOSE: Syndactyly surgical release is one of the most common congenital hand surgeries performed by pediatric hand surgeons. The purpose of our study was to evaluate the complications associated with syndactyly release and determine factors that correlate with higher complication rates within the 2-year postoperative period. METHODS: A retrospective chart review was completed for patients who underwent syndactyly release at a single pediatric center between 2005 and 2018. Patients were included if they had a diagnosis of syndactyly and underwent surgical release, and excluded for a diagnosis of cleft hand, incomplete surgical documentation, surgery performed at an outside institution, or follow-up care that did not extend beyond the first postoperative visit. Complications were classified using the Clavien-Dindo (CD) system. RESULTS: Fifty-nine patients met the inclusion criteria, which included 143 webs released in 85 surgeries. A total of 27 complications occurred for the 85 surgeries performed. The severity of complications was CD grade I or II in 23% of surgeries, most commonly unplanned cast changes, and CD grade III in 8% of surgeries. No CD grade IV or V complications occurred. The CD grade III complications included 6 reoperations. The complication rate was higher when performing >1 syndactyly release per surgery. It also was higher for patients undergoing >1 surgical event. Rates of complication per surgery were similar between patients with multiple surgeries compared with those with a single surgery. Concomitant diagnoses and complexity of syndactyly was not associated with a higher complication rate. CONCLUSIONS: Syndactyly release was associated with a complication rate of 31% per surgical event with 44% of these complications related to unplanned cast changes and 8% of complications that required admission or reoperation. Risk factors for complications following syndactyly release include >1web operated on per surgery and undergoing >1 surgical event. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognosis IV.

The Impact of Isolated Versus Multiple Osteochondromas: Analysis of the CoULD Registry.

PURPOSE: The burden of upper extremity (UE) osteochondromas on function and self-perception among pediatric patients is unclear. The purpose of our study was to study the impact of osteochondromas in comparison to population norms and to evaluate solitary versus multiple osteochondromas on subjective UE function as measured by patient rated outcomes. METHODS: We utilized the CoULD (Congenital Upper Limb Differences) Registry to review all pediatric patients presenting with osteochondromas between January 2014 and February 2021. Demographic information was collected and patients were classified as having either single or multiple osteochondromas. Patient-Reported Outcome Measurement Information System (PROMIS) and Pediatric Outcomes Data Collection Instrument (PODCI) tools were utilized for assessment. Scores for PODCI subscales of UE function, Pain/comfort, and Happiness and PROMIS domains of UE Function, Pain, Depression, Anxiety, and Peer Relations were reviewed. Differences between groups were analyzed using the Student t test. RESULTS: Ninety-nine patients met inclusion criteria for the study with an average age of presentation of 9.3 years and 61 patients (62%) were male. Overall, patients demonstrated worse UE Function as well as greater Anxiety and Depression in comparison to the population normals on PROMIS assessment. Patients also demonstrated worse patient and parent reported PODCI UE, Sports and Physical Functioning, Pain/Comfort and Global Functioning scores compared with population norms but demonstrated better than average happiness scores. Patients with multiple osteochondromas demonstrated greater PROMIS pain interference and more disability in PODCI Sports and Physical Functioning, Pain/Comfort and Global Functioning compared with those with solitary osteochondromas. CONCLUSION: Patients with UE osteochondromas have worse overall function in comparison to population norms, exceeding established minimally clinically important difference values. In addition, patients with multiple osteochondromas reported more pain and poorer physical function than those with solitary osteochondromas. Physicians should be alert to the physical and psychosocial burden of this disease. LEVEL OF EVIDENCE: Level II-prognostic.

A Comparative Analysis of 150 Thumb Polydactyly Cases from the CoULD Registry Using the Wassel-Flatt, Rotterdam, and Chung Classifications.

PURPOSE: Three commonly used classifications for thumb polydactyly are the Wassel-Flatt, Rotterdam, and Chung. The ideal classification system would have high validity and reliability and be descriptive of the thumb anomaly. The purposes of this investigation were to (1) compare the inter- and intrarater reliability of these 3 classifications when applied to a large sample of patients enrolled in the Congenital Upper Limb Differences (CoULD) Registry and (2) determine the prevalence of radial polydactyly types when using the various classifications in a North American population. METHODS: Inter- and intrarater reliability were determined using 150 cases of radial polydactyly presented in a Web-based format to 7 raters in 3 rounds, a preliminary training round and 2 observation rounds. Raters classified each case according to the Wassel-Flatt, Rotterdam, and Chung classifications. Inter- and intrarater reliability were evaluated with the intraclass correlation coefficient (ICC) calculated using 2-way random measures with perfect agreement. RESULTS: For Wassel-Flatt, both the interrater (ICC, 0.93) and the intrarater reliability (ICC, 0.91) were excellent. The Rotterdam classification had excellent reliability for both interrater reliability (ICC, 0.98) and intrarater reliability (ICC, 0.94), when considering type alone. Interrater analysis of the additional subtypes demonstrated a wide range of reliabilities. The Chung classification had good interrater (ICC, 0.88) and intrarater reliability (ICC, 0.77). Within the Wassel-Flatt classification, the most frequent unclassifiable thumb was a type IV hypoplastic thumb as classified by the Rotterdam classification. CONCLUSIONS: The Wassel-Flatt and Rotterdam classifications for radial polydactyly have excellent inter- and intrarater reliability. Despite its simplicity, the Chung classification was less reliable in comparison. The Chung and Rotterdam classification systems capture the hypoplastic subtypes that are unclassifiable in the Wassel-Flatt system. Addition of the hypoplastic subtype to the Wassel-Flatt classification (eg, Wassel-Flatt type IVh) would maintain the highest reliability and classify over 90% of thumbs deemed unclassifiable in the Wassel-Flatt system. CLINICAL RELEVANCE: The Wassel-Flatt and Rotterdam classifications have excellent inter-and intrarater reliability for the hand surgeon treating thumb polydactyly. Addition of a hypoplastic subtype to the Wassel-Flatt (Type 4h) allows classification of most previously unclassifiable thumbs.

What Proportion of Orthopaedic Surgery Residency Programs Have Accessible Parental Leave Policies, and How Generous are They?

BACKGROUND: Parental leave during graduate medical education is a component of wellness in the workplace. Although every graduate medical education program is required by the Accreditation Council for Graduate Medical Education (ACGME) to have a leave policy, individual programs can create their own policies. The ACGME stipulates that "the sponsoring institution must provide a written policy on resident vacation and other leaves of absence (with or without pay) to include parental and sick leave to all applicants." To our knowledge, a review of parental leave policies of all orthopaedic surgery residency programs has not been performed. QUESTION/PURPOSES: (1) What proportion of orthopaedic surgery residency programs have accessible parental (maternity, paternity, and adoption) leave policies? (2) If a policy exists, what financial support is provided and what allotment of time is allowed? METHODS: All ACGME-accredited orthopaedic surgery residency programs in 2017 and 2018 were identified. One hundred sixty-six ACGME-accredited allopathic orthopaedic surgery residency programs were identified and reviewed by two observers. Reviewers determined if a program had written parental leave policy, including maternity, paternity, or adoption leave. Ten percent of programs were contacted to verify reviewer findings. The search was sequentially conducted starting with the orthopaedic surgery residency program's website. If the information was not found, the graduate medical education (GME) website was searched. If the information was not found on either website, the program was contacted directly via email and phone. Parental leave policies were classified as to whether they provided dedicated parental leave pay, provided sick leave pay, or deferred to unpaid Family Medical Leave Act (FMLA) policies. The number of weeks of maternity, paternity, and adoption leave allowed was collected. RESULTS: Our results showed that 3% (5 of 166) of orthopaedic surgery residency programs had a clearly stated policy on their program website. Overall, 81% (134 of 166) had policy information on the institution's GME website; 7% (12 of 166) of programs required direct communication with program coordinators to obtain policy information. Further, 9% (15 of 166) of programs were deemed to not have an available written policy as mandated by the ACGME. A total of 21% of programs (35 of 166) offered designated parental leave pay, 29% (48 of 166) compensated through sick leave pay, and 50% (83 of166) deferred to federal law (FMLA) requiring up to 12 weeks of unpaid leave. CONCLUSIONS: Although 91% of programs meet the ACGME requirement of written parental leave policies, current parental leave policies in orthopaedic surgery are not easily accessible for prospective residents, and they do not provide clear compensation and length of leave information. Only 3% (5 of 166) of orthopaedic surgery residency programs had a clearly stated leave policy accessible on the program's website. Substantial improvements would be gained if every orthopaedic residency program clearly outlined the parental leave policy on their residency program website, including compensation and length of leave, particularly in light of the 2019 American Board of Orthopaedic Surgery changes allowing time away to be averaged over the 5 years of training. CLINICAL RELEVANCE: Parental leave policies are increasingly relevant to today's trainees []. Applicants to orthopaedic surgery today value work/life balance including protected parental leave [].

Preoperative Antibiotics in Wrist Arthroscopy.

PURPOSE: This study seeks to evaluate the need for preoperative antibiotics for wrist arthroscopy. METHODS: A retrospective review of 576 consecutive wrist arthroscopies was performed over a 10-year period at a single ambulatory surgery center. The chart of each included patient was reviewed for postoperative infections following the National Nosocomial Infections Surveillance criteria for diagnosis. RESULTS: Of the 576 wrist arthroscopies reviewed, 324 met the inclusion criteria. Preoperative antibiotics were administered in 209 cases (65%) and not administered in 115 cases (35%). There were 116 cases (36%) with concomitant open soft tissue procedures. We identified 2 infections (0.6% overall infection rate), both of which were in patients who had received preoperative antibiotics. Both of these patients underwent concomitant percutaneous pinning of carpal bones with Kirschner wires, which were buried beneath the skin. CONCLUSIONS: Administering preoperative antibiotics for routine wrist arthroscopy does not appear to lower the surgical site infection rate. The rate of surgical site infection is so low in both cohorts that a meaningful difference cannot be determined between the 2 groups. This study adds to the current body of literature suggesting that it is acceptable practice to withhold preoperative antibiotics for surgeries that have a very low rate of infection. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Patient-reported outcomes after open carpal tunnel release using a standard protocol with 1 hand therapy visit.

STUDY DESIGN: Retrospective case series. INTRODUCTION: Open carpal tunnel release (OCTR) is a common treatment for carpal tunnel syndrome, but there is no consensus on the number of hand therapy visits needed to achieve optimal patient outcomes. PURPOSE OF THE STUDY: The purpose is to examine changes in patient-reported symptoms and function over a 12-week period after OCTR with 1 postoperative hand therapy visit. METHODS: Eligible subjects were consecutive patients treated with a standard OCTR protocol by a fellowship trained hand surgeon that included 1 hand therapy visit at 10-14 days postoperatively. Patients were excluded from participation if they had additional surgery at the time of OCTR, had another upper extremity diagnosis that required therapeutic intervention, or received more or less than 1 visit of hand therapy. Responses on the Boston Carpal Tunnel Questionnaire (BCTQ) were collected at preoperative and 3 postoperative time points: at the hand therapy visit, 6 weeks, and 12 weeks. Change over time in the BCTQ Symptom Severity Scale and Functional Status Scale was assessed. RESULTS: A total of 134 patients who were treated with the standard protocol had a complete BCTQ data set. Both BCTQ scales showed significant improvement over time. The Symptom Severity Scale showed significant improvement by the hand therapy visit at 10-14 days postoperatively, whereas significant improvement on the Functional Status Scale did not occur until 6 weeks postoperatively. The magnitude of change from preoperative to 12 weeks postoperative was 1.51 points on the Symptom Severity Scale and 0.91 points on the Functional Status Scale. Complication rates were low with an incidence of 13% for pillar pain and palm pain combined. CONCLUSIONS: Patient-reported symptoms and function improved significantly up to 12 weeks after OCTR. Moreover, there was a low incidence of pillar and palm pain. In a retrospective review of patients with a favorable prognosis based on having no need for extra surgical procedures or additional therapy visits, one therapy visit associated with improvements in symptoms and function, a low incidence of pillar/palm pain and favorable 12-weeks outcomes. There appears to be a subset of less complicated patients for whom one visit can allow for favorable outcomes. LEVEL OF EVIDENCE: 2B.

Epidemiology of congenital upper limb anomalies in a midwest United States population: an assessment using the Oberg, Manske, and Tonkin classification.

PURPOSE: To examine the relative presentation frequency of children with upper limb congenital anomalies at 3 Midwestern referral centers using the Oberg, Manske, and Tonkin (OMT) classification and to assess the utility of this new classification system. METHODS: 641 individuals with 653 congenital upper extremity anomalies were identified at 3 hospitals in 2 large metropolitan areas during a 1-year interval. Patients were identified prospectively and the specific upper extremity anomaly and any associated syndromes were confirmed using medical records and radiographs. We applied the OMT classification that categorizes anomalies using a dysmorphology outline as malformations, dysplasias, deformations, and syndromes, and assessed its utility and ease of use. RESULTS: There were 480 extremities (74%) with a limb malformation including 184 involving the entire limb. Arthrogryposis was the most common of these (53 extremities). Anomalies affecting only the hand plate accounted for 62% (296) of the malformations. Of these, radial polydactyly (15%) was the most common specific anomaly, followed by symbrachydactyly (13%) and cleft hand (11%). Dysplasias were noted in 86 extremities; 55 of these were multiple hereditary exostoses. There were 87 extremities with deformations and 58 of these were trigger digits. A total of 109 children had a syndrome or association. Constriction ring sequence was most common. The OMT was straightforward to use and most anomalies could be easily assigned. There were a few conditions, such as Madelung deformity and symbrachydactyly, that would benefit from clarification on how to best classify them. CONCLUSIONS: Malformations were the most common congenital anomalies in the 653 upper extremities evaluated over a 1-year period at 3 institutions. We were able to classify all individuals using the OMT classification system.

Hand function with touch screen technology in children with normal hand formation, congenital differences, and neuromuscular disease.

PURPOSE: To measure and compare hand function for children with normal hand development, congenital hand differences (CHD), and neuromuscular disease (NMD) using a function test with touch screen technology designed as an iPhone application. METHODS: We measured touch screen hand function in 201 children including 113 with normal hand formation, 43 with CHD, and 45 with NMD. The touch screen test was developed on the iOS platform using an Apple iPhone 4. We measured 4 tasks: touching dots on a 3 × 4 grid, dragging shapes, use of the touch screen camera, and typing a line of text. The test takes 60 to 120 seconds and includes a pretest to familiarize the subject with the format. Each task is timed independently and the overall time is recorded. RESULTS: Children with normal hand development took less time to complete all 4 subtests with increasing age. When comparing children with normal hand development with those with CHD or NMD, in children aged less than 5 years we saw minimal differences; those aged 5 to 6 years with CHD took significantly longer total time; those aged 7 to 8 years with NMD took significantly longer total time; those aged 9 to 11 years with CHD took significantly longer total time; and those aged 12 years and older with NMD took significantly longer total time. CONCLUSIONS: Touch screen technology has becoming increasingly relevant to hand function in modern society. This study provides standardized age norms and shows that our test discriminates between normal hand development and that in children with CHD or NMD. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic III.

Treatment of blocked elbow flexion in congenital radioulnar synostosis with radial head excision: a case series.

BACKGROUND: Congenital radioulnar synostosis (CRUS) causes a spectrum of presentations, most commonly a restriction of forearm rotation. Because most of these children are not treated operatively, many are not followed clinically after the diagnosis has been made. This report describes that a subset of the Cleary and Omer type IV synostoses (anterior dislocation of the radial head) can present with a progressive block to elbow flexion that worsens with growth. The location of this synostosis allows the physis of the radial head to grow untethered. The enlarged radial head can impinge upon the capitellum, blocking elbow flexion and snapping on the annular ligament. We propose excision of the radial head as a method of treating the anteriorly dislocated radial head in type IV synostoses. METHODS: We evaluated 4 patients with Cleary and Omer type IV synostoses who presented with an anteriorly dislocated radial head impinging on elbow flexion with snapping of the annular ligament. Each patient was treated with excision of the radial head. RESULTS: In 4 patients excision of the radial head was performed through a lateral Kocher approach. At follow-up, all patients showed relief from their pain and mechanical symptoms, with return of baseline range of motion. One complication which occurred was transient radial nerve neuropraxia. CONCLUSIONS: Although surgery is rarely needed for CRUS, excision of the radial head may be indicated if progressive loss of elbow flexion occurs secondary to impingement of the anteriorly dislocated radial head with the distal humerus in patients with type IV synostosis. We report that excision of the radial head can successfully treat this condition. Patients with type IV CRUS should be educated about the potential for loss of elbow flexion and/or followed until skeletal maturity to evaluate for this potential condition. LEVEL OF EVIDENCE: Case series consistent with level IV evidence; therapeutic study.

Congenital Upper-Limb Differences: A 6-Year Literature Review.

➤ The Oberg-Manske-Tonkin (OMT) classification of congenital hand and upper-limb anomalies continues to be refined as our understanding of the genetic and embryonic etiology of limb anomalies improves.➤ We have conducted an evaluation of graft and graftless techniques for syndactyly reconstruction; strengths and drawbacks exist for each technique.➤ Treatment for radial longitudinal deficiency remains controversial; however, radialization has shown promise in early follow-up for severe deformities.➤ Recent emphasis on psychosocial aspects of care has demonstrated that children with congenital upper-limb differences demonstrate good peer relationships and marked adaptability.

The Minimum Clinically Important Difference for the Patient-Rated Wrist Evaluation in Surgical Fixation of Distal Radius Fractures: Does Hand Dominance Make a Difference?

BACKGROUND: Distal radius fractures (DRFs) are common orthopaedic injuries. They can be treated in many ways, but the volar locking plate (VLP) is more frequent. Currently, there is limited information regarding the minimum clinically important difference (MCID) in surgically treated DRFs. The purpose of this study was to calculate MCID values for the Patient-Reported Wrist Evaluation (PRWE) in the setting of VLP-treated DRFs. METHODS: A retrospective review was conducted for patients with isolated, surgically-treated DRFs with a VLP. Exclusions included any concomitant procedure other than a carpal tunnel release, skeletal immaturity, polytrauma, open fracture, or missing PRWE data. MCID was calculated using PRWE, an overall health question, and the anchor-based method. RESULTS: A total of 131 patients were identified. Approximately 54.2% injured their dominant hand. AO/OTA classification 23C was the most common (n=89, 67.9%). Average baseline, 6-week, and 12-week PRWE were 71.8 ± 19.6, 34.3 ± 20.1, and 21.2 ± 18.0 respectively. This corresponds to an average change from baseline PRWE at 6 weeks and 12 weeks of -37.5 ± 23.4 and -50.6 ± 22.3, respectively. Average MCID values for 6 weeks and 12 weeks were 43.1 ± 18 and 56.0 ± 20.0, respectively (p<0.001). Hand dominance did not correlate with MCID value (rs = 0.084 at six weeks, rs = 0.099 at 12 weeks). MCID value additionally did not correlate with sex, AO/OTA classification, smoking status, ASA score, or BMI. Treatment at a level 1 trauma center and diagnosis of anxiety and/or depression correlated with a higher 6-week MCID value (rs = 0.308 and rs = 0.410, respectively). Increasing age weakly correlated with higher 12-week MCID value (rs = 0.352). CONCLUSIONS: This study demonstrated an MCID calculation using an overall health anchor. MCID value varied with follow-up time and correlated weakly with age, diagnosis of anxiety and/or depression, and treatment facility, but it did not correlate with injury of the dominant hand. Future research should analyze how to apply MCID and identify successful treatment in the setting of DRF care.

Implant cost variation in surgically treated distal radius fractures.

Aims & objectives: The purpose of this study was to evaluate for cost variation in distal radius fractures (DRFs) treated with a volar locking plate (VLP) and to identify key factors that affect the total construct cost. Materials & methods: A retrospective case series was conducted for a single healthcare system. A total of 140 patients with a DRF treated with a VLP from May 2014 to December 2021 were identified. Patients were excluded for polytrauma, open fractures, and skeletal immaturity. Results: Most patients were female (n = 120, 85.7%) and were on average 59 ± 13.7 years old. Patients most often injured their dominant hand (n = 75, 53.6%) and presented with an AO/OTA 23C fracture (n = 93, 66.4%). Twenty-two surgeons were included with fellowship training in hand or trauma and orthopaedic or plastic surgery residency. Orthopaedic hand-trained surgeons treated the highest proportion of 23C fractures (69.8%). Ninety patients (64.3%) were treated at a surgery center. The average cost was $1289.67 ± $215.32 (range: $857.83-$2156.95). The most expensive fixation constructs used a variable angle locking screw ($1316.75 ± $264.99) or a multidirectional threaded peg ($1321.67 ± $192.94). Multivariable regression analysis revealed none of the study variables to be significant contributors to construct cost (all p-values >0.27). Conclusions: Surgically treated DRFs with a VLP demonstrated similar total implant costs regardless of fracture pattern, surgeon specialty, or treatment facility. Contrary to previous literature, VLPs showed minimal cost variation, although some surgeons were able to decrease the overall cost by reducing the number of screws used.

A Case Series of Surgically Treated Distal Radius Fractures: Implant Costs and Their Effect on Patient Outcomes.

INTRODUCTION: Distal radius fractures (DRFs) are common injuries, warranting a need to analyze the cost of treatment. The purpose of this study was to analyze the effect of implant costs on patient-reported outcomes in DRFs. METHODS: A PRO registry was retrospectively reviewed for isolated, surgically treated DRF patients. A total of 140 patients met criteria to be included in this study. Implant cost was obtained from the chargemaster database. RESULTS: The average total implant cost was $1,289.67 ± 215.32. The average Patient-rated Wrist Evaluation scores preoperatively, at 6 weeks, and at 12 weeks were 70.8 ± 20.1, 36.6 ± 21.1, and 22.8 ± 18.0, respectively. No statistically significant relationships were observed between cost and Patient-rated Wrist Evaluation scores at 6 weeks or 12 weeks (r = -0.05, P = 0.59; r = -0.04, P = 0.64, respectively). Implant costs were shown to not be affected by fracture complexity (AO/OTA classification: 23A = $1,335.50, 23B = $1,246.86, and 23C = $1,293.14). DISCUSSION: The total cost of implants did not influence patient outcomes indicating that patients receive no additional benefit from more costly constructs.

Comparison of Orthosis Management Failure Rates for Mallet Injuries.

Purpose: A closed mallet injury is a common finger injury involving terminal extensor tendon avulsion from its insertion on the distal phalanx. Nonsurgical treatment with continuous extension orthosis fabrication is the preferred treatment. Our purpose was to report the failure rates of orthotic management by digit and investigate other factors that contribute to failure. Methods: This was a retrospective chart review of all patients with an isolated mallet finger injury managed at our institution from 2011 to 2019. Patient demographics, details of management, and treatment outcomes were collected. Failure rates were compared for all digits, specifically comparing the little finger versus all other digits. A categorical variable analysis was performed to identify risk factors for failure of orthosis management. Results: Out of 1,331 identified patients, 328 met the inclusion criteria. There was no statistically significant difference of failure rate between digits. There was a trend toward the little finger failing at a higher rate (n = 131, 40%) than the other digits individually (P = .08) and combined (n = 95, 29%; P = .06). An older age at injury was associated with failure. The median patient age with failure was 54 years, versus the median patient age with nonfailure of 48 years (P < .01). The failure rate was higher in tendinous versus bony mallet injuries (n = 131, 40% vs n = 66, 20%, respectively; P < .01). The orthotic type was associated with the failure rate, and failure was highest in patients treated with Stack orthoses (n = 183, 56%; P = .01). Conclusions: There was no significant difference in the orthotic management failure rate by digit for a mallet injury. Statistically significant risk factors for failure are increasing age, a tendinous injury, and the orthotic type. Further evaluation with a larger cohort is warranted to increase the statistical power of the findings. Type of study/level of evidence: Therapeutic III.

How Risky Are Risk Factors? An Analysis of Prenatal Risk Factors in Patients Participating in the Congenital Upper Limb Differences Registry.

Purpose: Risk factors for congenital upper limb differences (CoULDs) are often studied at the general population level. The CoULD registry provides a unique opportunity to study prenatal risk factors within a large patient sample. Methods: All patients enrolled between June 2014 and March 2020 in the prospective CoULD registry, a national multicenter database of patients diagnosed with a CoULD, were included in the analysis. We analyzed self-reported, prenatal risk factors, including maternal smoking, alcohol use, recreational drug use, prescription drug use, gestational diabetes mellitus (GDM), and gestational hypertension. The outcome measures included comorbid medical conditions, proximal involvement of limb difference, bilateral involvement, and additional orthopedic conditions. Multivariable logistic regression was used to analyze the effect of the risk factors, controlling for sex and the presence of a named syndrome. Results: In total, 2,410 patients were analyzed, of whom 72% (1,734) did not have a self-reported risk factor. Among the 29% (676) who did have at least 1 risk factor, prenatal maternal prescription drug use was the most frequent (376/2,410; 16%). Maternal prescription drug use was associated with increased odds of patient medical comorbidities (odds ratio [OR] = 1.43, P = .02). Gestational diabetes mellitus was associated with increased odds of comorbid medical conditions (OR = 1.58, P = .04), additional orthopedic conditions (OR = 1.51, P = .04), and proximal involvement (OR = 1.52, P = .04). Overall, reporting 1 or more risk factors increased the odds of patient comorbid medical conditions (OR = 1.42, P < .001) and additional orthopedic conditions (OR = 1.25, P = .03). Conclusions: Most caregivers (72%) did not report a risk factor during enrollment. However, reporting a risk factor was associated with patient medical and orthopedic comorbidities. Of note, GDM alone significantly increased the odds of both these outcome measures along with proximal limb differences. These findings highlight the ill-defined etiology of CoULDs but suggest that prenatal risk factors, especially GDM, are associated with a higher degree of morbidity. Type of study/level of evidence: Prognostic III.

Reliability of Radiographic Imaging Characteristics for Osteochondritis Dissecans of the Capitellum.

BACKGROUND: A primary challenge in the treatment of capitellar osteochondritis dissecans (OCD) is accurate imaging assessment. Radiographic classification consensus is not available in the current literature, and correlation of radiographs with lesion stability and resultant best treatment is lacking. PURPOSE: To determine the inter- and intrarater reliability of the presence or absence and common radiographic characteristics of capitellar OCD lesions. STUDY DESIGN: Cohort study (Diagnosis); Level of evidence, 3. METHODS: Anteroposterior, lateral, and oblique radiographs for 29 cases were reviewed by 7 orthopaedic surgeons. Images were assessed for elbow anthropometry and morphology, OCD presence, lesion characteristics, the presence of progeny bone and progeny features, and radial head abnormalities. Intra- and interrater reliability was assessed using Fleiss and Cohen kappa for nominal variables and intraclass correlation coefficients (ICCs) for continuous variables. RESULTS: Surgeons demonstrated substantial to excellent inter- and intrarater reliability when assessing elbow characteristics: anthropometric (interrater ICC, 0.94-0.99; intrarater ICC, 0.82-0.96) and morphologic (Fleiss, 0.61-0.76; Cohen, 0.68). When the OCD lesion was assessed, fair to moderate interrater agreement was found for classifying the absence or presence of a lesion (Fleiss, 0.28-0.46) and the location of the OCD (Fleiss, 0.24-0.52), poor agreement for assessing the contour of the lesion (Fleiss, 0.00-0.09), and excellent agreement for measuring the size of the lesion (ICC, 0.82-0.94). Poor to fair interrater agreement was found for radial head abnormalities (Fleiss, 0.00-0.27). Progeny bone visualization and fragmentation demonstrated moderate interrater agreement (Fleiss, 0.43-0.47) where displacement of the bone demonstrated poor interrater agreement (Fleiss, 0.11-0.16). Intrarater agreement for OCD lesion characteristics, progeny bone visualization, and progeny bone features was moderate to excellent. CONCLUSION: Given only the fair to moderate agreement among raters for identifying OCD on radiographs, this imaging modality may not serve as a dependable screening tool in isolation. Additional imaging should be obtained if the clinical presentation suggests capitellar OCD and a definitive diagnosis is not possible with radiographs. However, clinicians can reliability measure the size of radiographically apparent OCD, suggesting that radiographs may serve as an appropriate imaging modality for follow-up care.
