Abstract
Background The etiology and pathogenesis of osteochondritis dissecans (OCDs) lesions remain controversial. Methods This review presents the recent evolution about the healing, imaging, pathogenesis, and how to treat OCD of the capitellum in overhead athletes. Results Compressive and shear forces to the growing capitellum can cause subchondral separation, leading to OCD, composed of 3 layers: articular fragment, gap, and underlying bone. Subchondral separation can cause ossification arrest (stage IA), followed by cartilage degeneration (stage IB) or delayed ossification (stage IIA), occasionally leading to osteonecrosis (stage IIB) in the articular fragment. Articular cartilage fracture and gap reseparation make the articular fragment unstable. The mean tilting angle of capitellar OCD is 57.6 degrees in throwers. Anteroposterior radiography of the elbow at 45 degrees of flexion (APR45) can increase the diagnostic reliability, showing OCD healing stages, as follows: I) radiolucency, II) delayed ossification, and III) union. Coronal computed tomography and magnetic resonance imaging with an appropriate tilting angle can also increase the reliability. MRI is most useful to show the instability, although it occasionally underestimates. Sonography contributes to detection of early OCD in adolescent throwers on the field. OCD lesions in the central aspect of the capitellum can be more unstable and may not heal. Cast immobilization has a positive effect on healing for stable lesions. Arthroscopic removal provides early return to sports, although a large osteochondral defect is associated with a poor prognosis. Fragment fixation, osteochondral autograft transplantation, and their hybrid technique have provided better results. Discussion Further studies are needed to prevent problematic complications of capitellar OCD, such as osteoarthritis and chondrolysis.

Abstract
PURPOSE To assess return to sport (RTS) in the high-risk young athlete population with capitellar osteochondritis dissecans (OCD) undergoing arthroscopic microfracture (MFX) with or without debridement as well as associated indications, clinical outcomes, radiographic outcomes, and complications. METHODS A literature search of all published literature in the English language from PubMed, EMBASE, Scopus, and Cochrane from database inception to April 4, 2022, was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Included studies presented demographics and outcomes for adolescent (<21 years old) patients diagnosed with capitellar OCD who underwent arthroscopic MFX (or drilling/subchondral drilling) or MFX (or drilling/subchondral drilling) with debridement (or loose body removal/chondroplasty). Studies containing multiple surgical techniques that did not distinguish characteristics and outcomes of individual patients by surgical technique were excluded. Additionally, if there was overlap in patient populations between 2 studies, the study with less outcome data was excluded. Extracted data included study properties, patient demographics, lesion characteristics, surgery details, and patient outcomes, including range of motion, outcome scores, and RTS rates. Bias was assessed via the Methodological Index for Non-Randomized Studies (MINORS). RESULTS Nine studies of 136 patients and 138 elbows met criteria. Included articles were published between 2005 and 2020 with MINORS scores of 8 to 14 (50% to 88%). The age ranged from 12.7 to 15.7 years with most patients being involved in baseball or gymnastics and a rate of dominant elbow involvement of 55% to 100%. Patient follow-up ranged from 16 to 138 months. All 9 studies reported RTS, ranging from 65% to 100%. Six of these studies categorized the level to which the patient returned, with patients RTS at the same level of competition ranging from 60% to 100%. Six studies reported complications, with a range rate of 0% to 43%; there were a total of 10 complications, 7 of which required reoperations. CONCLUSIONS Arthroscopic MFX with or without arthroscopic debridement is a safe and effective treatment for OCD lesions of the capitellum in young, athletic patients. Included studies reported improved clinical, radiographic, and patient-reported outcomes. Aside from 1 study reporting an RTS of 65%, the rate of RTS ranged from 86% to 100%. The percentage of patients returning to sport at the same level of competition ranged from 60% to 100% with a time to RTS ranging from 4.1 to 5 months. A single study reported a complication rate of 43%, while remaining studies reported complication rates between 0% and 19%, with loose bodies being the most common complication requiring reoperation. Follow-up ranged from 16 to 138 months. LEVEL OF EVIDENCE Level IV, systematic review of Level IV studies.

Abstract
A healthy articular cartilage is paramount to joint function. Cartilage defects, whether acute or chronic, are a significant source of morbidity. This review summarizes various imaging modalities used for cartilage assessment. While radiographs are insensitive, they are still widely used to indirectly assess cartilage. Ultrasound has shown promise in the detection of cartilage defects, but its efficacy is limited in many joints due to inadequate visualization. CT arthrography has the potential to assess internal derangements of joints along with cartilage, especially in patients with contraindications to MRI. MRI remains the favored imaging modality to assess cartilage. The conventional imaging techniques are able to assess cartilage abnormalities when cartilage is already damaged. The newer imaging techniques are thus targeted at detecting biochemical and structural changes in cartilage before an actual visible irreversible loss. These include, but are not limited to, T2 and T2* mapping, dGEMRI, T1ρ imaging, gagCEST imaging, sodium MRI and integrated PET with MRI. A brief discussion of the advances in the surgical management of cartilage defects and post-operative imaging assessment is also included.

Abstract
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.

Conservative treatment for stable osteochondritis dissecans of the elbow before epiphyseal closure: effectiveness of elbow immobilization for healing. J Shoulder Elbow Surg 2022; 31:1231-1241. [PMID: 35247573 DOI: 10.1016/j.jse.2022.01.148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2021] [Revised: 01/13/2022] [Accepted: 01/23/2022] [Indexed: 02/01/2023]
Abstract
BACKGROUND AND HYPOTHESIS Stable lesions of osteochondritis dissecans (OCD) of the capitellum have been treated with activity restriction (AR), and the complete healing requires 1 or 2 years. Little is known about the effectiveness of elbow immobilization. We hypothesized that elbow immobilization would have positive effects on healing of stable OCD. METHODS The study subjects were 43 patients (mean age: 12.2 years) with 43 stable OCD lesions of the prematured elbow (mean skeletal age score: 17.1 points of 0-27 points system). The subjects were divided into 3 groups: group A, AR without elbow immobilization, 22 cases; group B, splint (mean: 8.8 weeks) followed by AR, 9 cases; and group C, cast (mean: 3.7 weeks) followed by splint (mean: 7.3 weeks) and AR, 12 cases. The mean nonoperative observation period was 17.5 months (minimum three months). On anteroposterior radiographs of the elbow at 45 degrees of flexion, 5 observers independently assessed the healing of the capitellum, and the interobserver and intraobserver reliabilities were examined. The differences in outcomes among 3 groups were also examined. RESULTS The interobserver and intraobserver reliabilities of the radiographic assessment were almost perfect (Cohen kappa value: 0.82 and 0.91, respectively). There were no significant differences in age, sports played, or stage of the lesion before the treatment. The proportion of patients returning to sports and the mean period required were 77% and 8.2 months in group A, 78% and 5.7 months in group B, and 83% and 4.4 months in group C, respectively. The proportion of patients showing ossification in the central aspect of the capitellum and the mean period required were 67% and 8.2 months in group A, 63% and 4.9 months in group B, and 91% and 1.9 months in group C, respectively. The proportion of patients showing complete healing and the mean period required were 41% and 16.4 months in group A, 67% and 7.0 months in group B, and 92% and 5.5 months in group C, respectively. Compared to group A, group C showed a significantly earlier return to sports (P = .034), a significantly shorter period required for ossification (P < .001), and significantly higher proportion of patients with complete healing (P = .012) within a significantly shorter period (P = .009). CONCLUSION Elbow immobilization had positive effects on healing and enabled both an early return to sports and complete healing. Cast immobilization is recommended as a first choice of nonoperative treatment for stable OCD lesions of the elbow before epiphyseal closure.

Staging of osteochondritis dissecans of the elbow based on pathologic progression in the partially detached articular fragment. J Shoulder Elbow Surg 2022; 31:391-401. [PMID: 34478862 DOI: 10.1016/j.jse.2021.08.006] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2021] [Revised: 07/26/2021] [Accepted: 08/03/2021] [Indexed: 02/01/2023]
Abstract
BACKGROUND Osteochondritis dissecans (OCD) is considered to show the following stages of pathologic progression: IA, nearly normal-cartilaginous; IB, deteriorated-cartilaginous; IIA, cartilage-ossifying; and IIB, cartilage-osteonecrotic. However, the validity of this pathologic staging for OCD has yet to be confirmed in a large number of cases. PURPOSE The aim of the present study was to confirm the clinical validity of the proposed pathologic staging of OCD. METHODS The subjects were 74 patients (mean age, 14.2 years; mean skeletal age score, 25.6 points) with capitellar OCD. Partially detached articular fragments were surgically removed and were examined histologically. The articular fragments were independently assessed by 5 observers, and the reliability of assessment was examined. The correlation between the pathologic stages and the clinical data was analyzed. RESULTS The reliability of the assessment among 5 observers was almost perfect. OCD stages of IA, IB, IIA, and IIB were evident in 8, 36, 10, and 20 patients, respectively. OCD-I (cartilaginous) and OCD-II (osteochondral) corresponded significantly to radiographic stage I (radiolucency) and stage II (delayed ossification), respectively. The pathologic OCD stages were significantly correlated with the clinical data, including the period from symptom onset to surgery, patient age, and the skeletal age score (P < .01). CONCLUSION Our results confirmed that the proposed pathologic staging of OCD corresponds to the observed clinical progression of OCD, thus validating the staging system. Our findings revealed that OCD begins with separation beneath the epiphyseal cartilage, which is programmed to be replaced with bone. When a stage IA articular fragment has remained partially detached for a prolonged period, the epiphyseal cartilage may be deteriorated and become degenerated, and subsequent ossification may not occur, as is evident in OCD-IB. In contrast, stage IA with a vascular supply through the fibrocartilaginous connection can progress to stage IIA. During the prolonged period in which the osteochondral articular fragment remains ununited, microtrauma can cause to disturb the blood supply to the bony fragment, resulting in osteonecrosis (stage IIB).

Successful Nonoperative Treatment of Osteochondritis Dissecans of the Humeral Capitellum in a Young Baseball Player with Advanced Skeletal Maturity. Prog Rehabil Med 2021; 6:20210044. [PMID: 34825100 PMCID: PMC8590945 DOI: 10.2490/prm.20210044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Accepted: 10/13/2021] [Indexed: 11/14/2022] Open
Abstract
Background: Osteochondritis dissecans (OCD) of the humeral capitellum presents most typically in adolescent athletes who perform repetitive overhead activities. Earlier studies have demonstrated that conservative treatment of OCD is appropriate for patients with an open capitellar growth plate from the standpoint that spontaneous healing can be expected. Case: A 12-year-old male baseball player with two years of experience with a local team participated in our medical check that included screening for capitellar OCD using ultrasonography. The subject experienced elbow pain when throwing, and ultrasonographic elbow examination indicated OCD of the capitellum, detected as irregularity of the subchondral bone of the capitellum. The initial radiograph, taken with the elbow at 45° of flexion, identified new bone formation in the lateral aspect of the OCD lesion; however the epiphyseal lines of the capitellum and lateral epicondyle were closed. We advised the patient to stop heavy use of the elbow, e.g., throwing and batting, and started conservative treatment in anticipation of spontaneous healing. Physiotherapy focusing on the shoulder girdle, core, and hip and lower limb stretches were performed to resolve general tightness. The OCD lesion had healed completely 12 months after the start of conservative treatment. Discussion: Conservative treatment for young baseball players might be worth considering if lateral new bone formation within the OCD lesion is detected on radiographic findings, even if the epiphyseal lines of the capitellum and lateral epicondyle are closed.

Abstract
➤ Osteochondritis dissecans occurs most frequently in the active pediatric and young adult populations, commonly affecting the knee, elbow, or ankle, and may lead to premature osteoarthritis. ➤ While generally considered an idiopathic phenomenon, various etiopathogenetic theories are being investigated, including local ischemia, aberrant endochondral ossification of the secondary subarticular physis, repetitive microtrauma, and genetic predisposition. ➤ Diagnosis is based on the history, physical examination, radiography, and advanced imaging, with elbow ultrasonography and novel magnetic resonance imaging protocols potentially enabling early detection and in-depth staging. ➤ Treatment largely depends on skeletal maturity and lesion stability, defined by the presence or absence of articular cartilage fracture and subchondral bone separation, as determined by imaging and arthroscopy, and is typically nonoperative for stable lesions in skeletally immature patients and operative for those who have had failure of conservative management or have unstable lesions. ➤ Clinical practice guidelines have been limited by a paucity of high-level evidence, but a multicenter effort is ongoing to develop accurate and reliable classification systems and multimodal decision-making algorithms with prognostic value.

Abstract
OBJECTIVE Tennis is a popular sport with high levels of participation. This article aims to describe how upper extremity overuse injuries occur in relation to tennis biomechanics and to review their imaging characteristics and implications for management. In particular, we will review the imaging patterns of internal impingement, scapular dyskinesis, lateral and medial epicondylitis, ulnar collateral ligament insufficiency, valgus extension overload, capitellar osteochondritis dissecans, extensor carpi ulnaris tendinosis and instability, tenosynovitis, triangular fibrocartilage complex injuries, and carpal stress injuries. CONCLUSION Tennis is a complex and physically demanding sport with a wide range of associated injuries. Repetitive overloading commonly leads to injuries of the upper extremity. An understanding of the underlying mechanisms of injury and knowledge of these injury patterns will aid the radiologist in generating the correct diagnosis in both the professional and recreational tennis athlete.

Abstract
Background Little is known about the optimal timing of early return to sports after which the osteochondritis dissecans (OCD) lesion can completely heal. The aims of this study were to investigate the clinical outcomes of nonoperative treatment and elucidate the relationship between the radiographic findings and the timing for the return to sports. Methods We performed a retrospective review of 32 patients who presented with stable OCD of the capitellum and were treated nonoperatively for a minimum of 3 months. The mean follow-up period was 22.1 months. OCD lesions were assessed qualitatively and quantitatively on anteroposterior radiographs of the elbow at 45° of flexion every 3 months. The width of the OCD lesion (OCDw) and lateral width of the normal capitellum were measured and were associated with return to sports activities. Results In 21 patients (66%), the progression of ossification was seen at a mean period of 4.1 months. Eighteen (56%) had partial union at a mean period of 4.3 months. Twenty-nine cases (91%) returned to sports activities after a mean of 4.6 months. Nine cases (28%) achieved complete union after a mean period of 15.0 months. Fifteen (47%) required surgery after a mean period of 11.8 months. The mean OCDw (%) was 10.2 ± 3.9 mm (56%) at the initial presentation and 8.0 ± 6.0 mm (41%) at the final follow-up examination, and the decrease in OCDw was 2.2 ± 3.1 mm (15%). The mean decrease in OCDw in patients with progression of ossification during the first 3 months was significantly larger than in patients without progression of ossification (4.9 ± 4.7 mm and -0.7 ± 4.5 mm, respectively; P = .002). In patients who had both an OCDw value of <8.0 mm and a lateral width value of >2.0 mm at the time of the return to sports, the rate of successful nonoperative treatment (86%) and complete union (71%) was significantly higher in comparison with other patients (P = .03 and P = .02). Conclusions OCD lesions showed difficult healing in the middle one-third of the capitellum. The progression of ossification during the first 3 months was a significant predictor of successful nonoperative treatment and complete union. Surgery should be considered for lesions without the progression of ossification during the first 3 months. We propose both an OCD lesion width of <8.0 mm and a lateral normal width of >2.0 mm as radiographic landmarks of the timing of the return to sports.

Abstract
PURPOSE Factors that contribute to the development of juvenile osteochondritis dissecans (JOCD) of the talus are poorly understood. Some authors suggest that a higher loading of the affected zone may be a cofactor in osteochondral lesions. Therefore, the purpose of the study is to evaluate any association between ankle morphology and talus JOCD using morphologic parameters from magnetic resonance images. Our hypothesis is that ankles with JOCD lesions would have differences in the anatomy compared with age and sex-matched unaffected ankles. METHODS We evaluated a total of 75 extremities. There were 22 patients (25 ankles) with talus JOCD lesions, and 50 patients (50 ankles) sex and age-matched individuals with healthy ankles served as controls. Two examiners conducted independent measurements of 8 magnetic resonance images parameters: tibial anterior surface angle, tibial shaft both malleoli angle (TBM), tibial axis-medial malleolus angle, anterior opening angle of the talus, malleolar width, tibial lateral surface angle, Maximal tibial thickness, length of trochlea tali arc, and height of trochlea tali arc. Measurement reliability was assessed using intraclass correlation coefficients. Differences in parameters between JOCD patients and controls were evaluated using independent t test. The level of significance was taken to be P<0.05. RESULTS Intraclass correlation coefficients demonstrated good to excellent consistency for all measurements. Sagittal parameters demonstrated a significant length of trochlea tali arc increase in ankles with JOCD lesions compared with normal ankles (P=0.015). There was no statistical difference in any of the axial or coronal parameters. CONCLUSIONS Ankle morphology may have a relationship with JOCD lesions. Future larger studies will be useful for further clarifying our findings, and detecting other potential predisposing factors with clinical relevance and how they can be modified. STUDY DESIGN Cross-sectional study (Level of evidence III).

Abstract
BACKGROUND Although a variety of pathologic conditions associated with osteochondritis dissecans (OCD) have been reported, the pathological progression has remained unclear. HYPOTHESIS Separation of the immature epiphyseal cartilage is an early event in OCD, and osteonecrosis in the articular fragment is a late event. STUDY DESIGN Case Series; Level of evidence, 4. METHODS The participants were 26 boys (mean age, 13.8 years; mean skeletal age score for the elbow, 24.6 points) with capitellar OCD who underwent osteochondral autograft transplantation. A total of 28 cylindrical osteochondral plugs, including the articular fragment, an intermediate layer, and proximal epiphyseal bone, were harvested from the central area of the capitellum and were examined histologically. The articular fragments of OCD were independently assessed by 5 observers and divided into 4 pathological variations: IA, nearly normal-cartilaginous; IB, deteriorated-cartilaginous; IIA, cartilage-ossifying; and IIB, cartilage-osteonecrotic. The reliability of assessment and the correlation of the pathological variations with the clinical data were examined. RESULTS The reliability of the assessment among 5 observers was almost perfect (Cohen kappa value = 0.91). OCD variations of IA, IB, IIA, and IIB were evident in 5, 10, 5, and 6 patients, respectively. OCD-I (cartilaginous) and OCD-II (osteochondral) corresponded significantly to radiographic stage I (radiolucency or slight calcification with open physis) and stage II (delayed ossification or bony fragment), respectively (Cohen kappa value = 0.79; percentage agreement = 81%). The pathological OCD variations were significantly correlated with the clinical data, including the period from symptom onset to surgery, patient age, and the skeletal age score (P < .01, in each). CONCLUSION The present study has revealed that the pathological variations correspond to the progression of OCD, thus proving our hypothesis. OCD-IA was shown to be an early lesion caused by separation of the immature epiphyseal cartilage. OCD-IB appeared to result from ossification arrest over a prolonged period from the onset of OCD-IA, whereas OCD-IIA showed delayed ossification in the epiphyseal cartilage where vascularization from the surrounding bone had been established. Osteonecrosis in OCD-IIB was shown to be a late pathological event caused by disruption of the vascular supply to OCD-IIA.

Abstract
Background Repetitive mechanical stress on the elbow joint during throwing is a cause of ulnar collateral ligament dysfunction that may increase the compressive force on the humeral capitellum. This study aimed to examine the effects of ulnar collateral ligament material properties on the humeral capitellum under valgus stress using the finite element method. Methods Computed tomography data of the dominant elbow of five healthy adults were used to create finite element models. The elbows were kept at 90° of flexion with the forearm in the neutral position, and the ulnar collateral ligament was reproduced using truss elements. The proximal humeral shaft was restrained, and valgus torque of 40 N·m was applied to the forearm. The ulnar collateral ligament condition was changed to simulate ulnar collateral ligament dysfunction. Ulnar collateral ligament stiffness values were changed to 72.3 N/mm, 63.3 N/mm, 54.2 N/mm, 45.2 N/mm, and 36.1 N/mm to simulate ulnar collateral ligament laxity. The ulnar collateral ligament toe region width was changed in increments of 0.5 mm from 0.0 to 2.5 mm to simulate ulnar collateral ligament loosening. We assessed the maximum equivalent stress and stress distribution on the humeral capitellum under these conditions. Results As ulnar collateral ligament stiffness decreased, the maximum equivalent stress on the humeral capitellum gradually increased under elbow valgus stress (P < .001). Regarding the change in the ulnar collateral ligament toe region width, as the toe region elongated, the maximum equivalent stress of the humeral capitellum increased significantly under elbow valgus stress (P < .001). On the capitellum, the equivalent stress on the most lateral part was significantly higher than that on other parts (P < .01 for all). Conclusion Under elbow valgus stress with elbow flexion of 90° and the forearm in the neutral position, ulnar collateral ligament dysfunction increased equivalent stress on the humeral capitellum during the finite element analysis. The highest equivalent stress was noted on the lateral part of the capitellum.

Abstract
Osteochondritis dissecans (OCD) of the capitellum is a relatively rare condition, with a higher incidence in adolescents who participate in repetitive overhead sports. The surgical treatment approach for this uncommon problem has varied from microfracture, loose body removal, abrasion chrondroplasty, lesion fixation, osteochondral allograft transplantation surgery, and osteochondral autologous transplantation surgery. The purpose of this study is to present the authors' preferred surgical technique for the treatment of unstable OCD lesions of the capitellum with osteochondral autologous transplantation surgery using autograft from the ipsilateral knee.

Abstract
Background Even in patients with an open capitellar physis, nonsurgical treatment for advanced-stage osteochondritis dissecans (OCD) of the capitellum often yields poor outcomes. However, surgical methods for such patients are controversial. At our institution, we have consistently performed closed-wedge osteotomy of the distal humerus to treat advanced-stage OCD of the capitellum, regardless of the OCD grade or condition of the capitellar physis. Purpose To clarify the clinical and radiological results and determine the influence of the capitellar physis on closed-wedge osteotomy for advanced-stage OCD of the capitellum in young patients. Study Design Case series; Level of evidence, 4. Methods A total of 32 patients with OCD of the humeral capitellum were treated surgically with closed-wedge osteotomy. Of these, 17 patients with more than 2-year follow-up were available for an evaluation. The mean patient age was 11.8 years (range, 11-12 years), and the mean follow-up period was 70.1 months (range, 25-184 months). The clinical assessment included range of motion, elbow pain, and the Japanese Orthopaedic Association (JOA) and Timmerman-Andrews scores. The radiological assessment at the final examination included cross-bridging of the physis, size and fishtail deformity of the distal part of the humerus, size of the radial head, healing of the OCD lesion, and osteoarthritis. Results The mean range of motion and JOA and Timmerman-Andrews scores improved significantly after surgery; 13 patients were completely pain free. In 11 patients with an open capitellar physis, metaphyseal-epiphyseal, cross-bridging was observed in 1 patient. A fishtail deformity of the distal part of the humerus was not observed. Healing of the OCD lesion was defined as excellent in 9 patients, good in 3, fair in 3, and poor in 2. In 3 of the 5 patients in whom healing was described as fair or poor, there was a lesion of the lateral widespread type with osteoarthritis before surgery. Moderate osteoarthritic changes were evident in 2 patients. Conclusion Closed-wedge osteotomy for the treatment of advanced-stage OCD of the capitellum in young patients can provide satisfactory clinical and radiological results. However, fair and poor outcomes were found in lateral widespread-type cases with osteoarthritis before surgery. We believe that patients in whom osteoarthritic changes have not yet appeared are eligible for closed-wedge osteotomy.

Abstract
PURPOSE The primary outcomes are the evaluation and quantification of pain relief and improvement in range of motion after OAT in OCD. The secondary outcomes are: resuming of sport activities, evaluation of the ADL recovery rate and subjective evaluation of the quality of life improvement. METHODS Nine patients, affected by an unstable and non-acute OCD lesion of the capitulum humeri, have been treated by the same surgeon. The patient mean age was 22.4 (16-45 years). All subjects were treated with the same surgical technique (arthroscopic OAT from the same side knee, a single cylinder of 6.5-9 mm in diameter) and underwent the same rehabilitation. The mean follow-up was 48 months (30-52 months). The authors documented the clinical assessment of each patient and carried out a questionnaire which included the VAS scale, MEPS Score and Quick DASH score. Patients were asked for MRI and radiographs pre- and post-operatively at follow-up. RESULTS The mean range of motion improvement was 17.9° in extension (range 13°-27°) and 10.6° in flexion (range 0°-20°) The VAS mean improvement was 7.1 (range 6-8) and the mean post-op value 0.6 (range 0-3). The MEPS score mean post-operative value was 98.3 (range 85-100). The Quick-DASH mean post-operative value was 2.5 (range 0-9.1) with a mean improvement of 41.4 points (range 36.4-47.7 points). All patients resumed sports in 6 months post-operatively. CONCLUSIONS The autologous transplant of an osteochondral plug is a safe and promising procedure. Despite being more demanding, the arthroscopic approach is a valuable tool if the surgeon aims to reduce the invasiveness of the procedure, with all the consequent advantages. LEVEL OF EVIDENCE IV Retrospective case series, therapeutic study.

Abstract
BACKGROUND Osteochondritis dissecans of the humeral capitellum (capitellar OCD) is a common injury among adolescent throwing athletes. Some younger patients with incomplete maturity of the epiphysis and early-stage capitellar OCD are good candidates for nonoperative treatment. However, during initial examination, predicting the need for surgical treatment in patients with capitellar OCD is difficult. PURPOSE To perform multivariate ordered logistic regression analysis of data obtained from patients' medical records and images on initial examination and identify the predictors of unsuccessful nonoperative management of capitellar OCD. STUDY DESIGN Cohort study (prognosis); Level of evidence, 2. METHODS This study included 245 elbows with capitellar OCD (all male; mean age, 14 years [range, 10-27 years]). Patients were divided into 3 groups comprising 148 elbows requiring an immediate operation on initial examination, 48 requiring nonsurgical treatment, and 49 requiring an operation after nonoperative management. Baseline data and radiographic parameters, such as lesion location, lesion size, modified Minami classification, radial head size, skeletal age difference between both elbows on initial examination, lesion size on computed tomography, and staging on magnetic resonance imaging, were retrospectively reviewed. Univariate and multivariate ordered logistic regression analyses of spontaneous healing of the lesion were conducted. RESULTS Univariate logistic regression analysis showed that radial head enlargement and skeletal age difference were significantly associated with spontaneous healing. In multivariate ordered logistic regression analysis, radial head enlargement (anteroposterior and lateral) and skeletal age difference were significant predictors of lack of spontaneous healing (odds ratio [OR], 2.76, P =.025; OR, 7.92, P =.026; and OR, 1.84, P =.0089, respectively). CONCLUSION To predict spontaneous healing in the moderate stage, plain radiographs would be important to evaluate radiocapitellar congruity and skeletal age. This study showed that preoperative radiographic findings of radial head enlargement and advanced skeletal age of the throwing side compared with that of the nonthrowing side were predictors of advanced-stage capitellar OCD. Despite several limitations, the statistical significance and correlations herein provide important information on preoperative surgical planning to surgeons.

Abstract
BACKGROUND Diagnosing capitellar osteochondritis dissecans (OCD) can be difficult, causing delay in treating young athletes. The main aim of this retrospective diagnostic study was to determine which radiological technique is preferred to identify and classify elbow OCD. METHODS We identified young patients who underwent elbow arthroscopy because of symptomatic OCD. We included all patients who had pre-operative radiographs, a computed tomography (CT) scan and magnetic resonance imaging (MRI) available. We assessed whether the osteochondral lesion could be identified using the various imaging modalities. All lesions were classified according to previous classifications for X-ray, CT and MRI, respectively. These results were compared with findings at arthroscopy. RESULTS Twenty-five patients had pre-operative radiographs as well as CT scans and MRI. In six patients, the lesion was not visible on standard X-ray. In 20 patients, one or two loose bodies were found during surgery, consistent with an unstable lesion. Pre-operatively, this was seen on 11 X-rays, 13 MRIs and 18 CT scans. CONCLUSIONS Capitellar OCD lesions are not always visible on standard X-rays. A CT appears to be the preferred imaging technique to confirm diagnosis of OCD. Loose bodies are often missed, especially on standard X-rays and MRIs.

Abstract
OBJECTIVE Juvenile osteochondritis dissecans (JOCD) is similar to osteochondrosis dissecans (OCD) in animals, which is the result of failure of the cartilage canal blood supply, ischemic chondronecrosis and delayed ossification, or osteochondrosis. The aim of the current study was to determine if osteochondrosis lesions occur at predilection sites for JOCD in children. METHOD Computed tomographic (CT) scans of 23 knees (13 right, 10 left) from 13 children (9 male, 4 female; 1 month to 11 years old) were evaluated for lesions consisting of focal, sharply demarcated, uniformly hypodense defects in the ossification front. Histological validation was performed in 11 lesions from eight femurs. RESULTS Thirty-two lesions consisting of focal, uniformly hypodense defects in the ossification front were identified in the CT scans of 14 human femurs (7 left, 7 right; male, 7-11 years old). Defects corresponded to areas of ischemic chondronecrosis in sections from all 11 histologically validated lesions. Intra-cartilaginous secondary responses comprising proliferation of adjacent chondrocytes and vessels were detected in six and two lesions, whereas intra-osseous responses including accumulation of chondroclasts and formation of granulation tissue occurred in 10 and six lesions, respectively. One CT cyst-like lesion contained both a pseudocyst and a true cyst in histological sections. CONCLUSION Changes identical to osteochondrosis in animals were detected at predilection sites for JOCD in children, and confirmed to represent failure of the cartilage canal blood supply and ischemic chondronecrosis in histological sections.

Abstract
BACKGROUND Capitellar osteochondritis dissecans (COCD) is a common elbow injury in young baseball athletes. It may be asymptomatic at the early stage and may progress if left untreated. This study investigated the effectiveness of ultrasonography (US) screening for COCD in adolescent baseball players and identified risk factors of COCD. METHODS A cross-sectional analysis study was conducted among baseball athletes aged 12 to 18 years. US screening of the throwing elbow was performed in all participants, and additional magnetic resonance imaging (MRI) was arranged for those with abnormal screening results. The prevalence of COCD was calculated according to MRI results. The US findings were compared with MRI findings. Data for characteristics, joint range of motion, and quality of pain were collected and analyzed using a logistic regression model to identify the risk factors of COCD. RESULTS A total of 299 adolescent baseball players were screened, and 17 were found to have COCD according to US findings. MRI was performed in 15 of these 17 players, and the MRI findings further confirmed COCD in 10 players (66.7%). The presence of elbow pain while at rest, body height, and age at introduction to baseball were predictors of COCD. CONCLUSIONS Although the effectiveness of diagnosing stage 1 COCD is satisfactory, US is a helpful tool for detecting stage 2 and higher-stage COCD. Elbow resting pain, lower body height, and introduction to baseball at a younger age are risk factors for COCD.

Abstract
Osteochondritis dissecans (OCD) of the humeral capitellum is a critical elbow injury in adolescent overhead throwing athletes. However, its etiology remains unknown. Medical examinations using ultrasonography found that the prevalence of capitellar OCD among adolescent baseball players was approximately from 1% to 3%. A plain anteroposterior radiograph with the elbow in 45° of flexion is essential for the diagnosis of an OCD lesion. The stability of OCD lesions is evaluated on plain radiographs, computed tomography, and magnetic resonance imaging (MRI). Imaging features of the unstable lesions are an epiphyseal closure of the capitellum or a lateral epicondyle, a displaced fragment, or irregular contours of the articular surface and a high signal interface on T2-weighted MRI. A stable lesion has the potential to be healed with conservative treatment. By contrast, surgical treatment should be considered if there is no radiographic improvement within 3 months. In addition, surgery should be performed for the lesions that cause pain during daily activities, have a locking phenomenon, or which are assessed by imaging as obviously unstable. Arthroscopic debridement/loose body removal can be performed for small lesions (≤12 mm in diameter). For large lesions (>12 mm), preservation and/or reconstruction of the articular surface should be selected, such as bone-peg fixation of the lateral part of the fragment and osteochondral autograft transplantation (OAT) from the knee. In the future directions, there is no comparative study of OAT from the knee and rib. In addition, little is known about its long-term outcome, or resulting osteoarthritis. A recent meta-analysis showed that grafts harvested from the knee may lead to donor site morbidity (7.8%). Thus, a novel cartilage tissue engineering approach is anticipated.

Abstract
PURPOSE OF REVIEW With an increasing rate of adolescent elbow injuries, especially in throwing athletes, the purpose of this review is to investigate the current literature regarding the diagnosis, treatment, and non-operative and operative outcomes of medial epicondyle fractures, ulnar collateral ligament repair, osteochondritis dissecans of the elbow, and olecranon stress fractures. RECENT FINDINGS Acceptable outcomes with both non-operative and operative treatments of medial epicondyle fractures have been reported, with surgical indications continuing to evolve. Unstable osteochondritis dissecans lesions, especially in patients with closed growth plates, require operative fixation, and emerging open and arthroscopic techniques including lesion debridement, marrow stimulation, autograft transfer, and allograft transplantation are described with good outcomes. Ulnar collateral repair has emerged as an exciting treatment option for an avulsion of either end of the ligament in young throwing athletes, with faster rehabilitation times than traditional ulnar collateral ligament reconstruction. Olecranon stress fractures are increasing in prevalence, and when a non-operative treatment course is unsuccessful, athletes have a high return-to-play rate after percutaneous cannulated screw placement. With proper indications, non-operative and operative treatment modalities are reported with a high return-to-play and acceptable clinical outcomes for common elbow injuries, including medial epicondyle fractures, ulnar collateral ligament repair, osteochondritis dissecans of the elbow, and olecranon stress fractures, in adolescent throwing athletes. Further research is needed to better define treatment algorithms, surgical indications, and outcomes.

Abstract
Background Capitellar osteochondritis dissecans (OCD) in skeletally immature athletes has often been seen in baseball players and gymnasts. The choice of surgical procedure for unstable lesions in skeletally immature athletes remains controversial. Purpose To investigate functional outcomes and radiographic changes in the midterm to long-term postoperative period after arthroscopic (AS) resection for small to large capitellar OCD lesions in skeletally immature athletes. Study Design Case series; Level of evidence, 4. Methods A total of 38 elbows in 38 patients (33 boys, 5 girls; mean age, 14 years [range, 13-15 years]) with skeletally immature elbows underwent AS resection for capitellar OCD. Patients were observed for at least 5 years (mean, 8 years [range, 5-12 years]). Elbows with a lesion width that did not exceed one-half of the radial head diameter were assigned to group 1 (n = 17 elbows), and larger lesions were assigned to group 2 (n = 21 elbows). Functional scores, patient satisfaction, range of motion (ROM), and osteoarthritis (OA) grades were evaluated between the groups. Results All patients returned to sports activity. Functional scores at the final follow-up were not significantly different between the groups. Patient satisfaction scores were significantly higher in group 1 than in group 2. There was significant improvement in flexion ROM at the final follow-up compared with preoperative values in group 1 (P = .017), and there was a significant between-group difference (group 1: 141°; group 2: 133°; P = .002). Extension ROM showed significant improvement in both groups (group 1: from -8° to 3°; group 2: from -17° to -1°; P < .001 for both). Group 1 tended to have better extension than group 2, but the difference was not significant. There were no elbows with severe OA in either group, but the OA grade progressed in 5 elbows (29%) in group 1 and 9 elbows (43%) in group 2, and this rate of OA progression was statistically significant between groups (P = .005). Conclusion Both functional outcomes and radiological findings after AS fragment resection were excellent in elbows with small lesions. Although overall outcomes were acceptable in elbows with larger lesions, flexion ROM and patient satisfaction scores were significantly inferior to those in elbows with smaller lesions.

Abstract
CASE We report the cases of 15-year-old male fraternal twins with bilateral osteochondritis dissecans (OCD) of the capitellum in the absence of syndromic features. At the time of presentation, they had been actively engaged in competitive rhythmic gymnastics for 3 years. Both patients had chronic symptoms in the right elbow, and both underwent arthroscopic evaluation and management. CONCLUSION The cases of these 2 patients provide evidence to support the theory that the etiology of OCD may have a genetic background.

Abstract
BACKGROUND There are excellent data supporting recommendations to prevent elbow injuries (osteochondritis dissecans [OCD] and ulnar collateral ligament [UCL] injuries), such as pitch count and pitch type in baseball, but anatomic risk factors have not been thoroughly examined. This study aimed to evaluate radiographic measurements in adolescents with elbow OCD lesions or UCL injuries and controls. METHODS We retrospectively identified adolescent patients between 2011 and 2016 with isolated capitellum OCD, UCL tear, or normal elbows based on magnetic resonance imaging. Nineteen patients (mean age, 13.5 years) had isolated OCD defects of the capitellum, 8 patients (mean age, 16.9 years) had isolated UCL complete tear, and the remaining 16 patients (mean age, 14.6 years) were normal controls. Radiographic measurements from corresponding anterior-posterior elbow radiographs were taken, including carrying angle, distal humeral articular surface angle, and radial neck-shaft angle. On the lateral radiograph, anterior angulation of the articular surface of distal humerus was measured. RESULTS Significant differences were observed in carrying angle between controls (15.7°) and OCD patients (11.6°; P = .03) as well as between controls and UCL patients (10.3°, P = .02), with the OCD and UCL patients tending to be in more varus. Significant differences were also found between controls (88.5°) and OCD patients (93.6°; P = .01) and between controls and UCL patients (93.3°; P = .03) in distal humeral articular surface angle, with OCD and UCL patients with increased valgus at the distal humerus articular surface. There were no significant differences between groups in radial neck-shaft angle or anterior angulation of articular surface of distal humerus. CONCLUSIONS Patients with OCD and UCL injuries have anatomic differences compared with normal controls that can be measured radiographically.

Abstract
PURPOSE To assess the histological properties of cells from displaced fragments obtained from patients with advanced osteochondritis dissecans (OCD) of the elbow and to examine whether these displaced fragments could be used as cell sources for autologous chondrocyte implantation. METHODS We harvested 6 displaced fragments from 6 patients who underwent osteochondral mosaicplasty for OCD of the elbow. The displaced fragments were examined histologically and digested to obtain chondrocytes. The cells obtained from young patients and skeletally matured cadaveric donors were examined using quantitative reverse transcription polymerase chain reaction analysis to quantify the expression of chondrocyte marker genes. The cells were cultured in atelocollagen, and the properties of 3-dimensional cultured cartilage were examined. RESULTS All 6 displaced fragments contained hyaline cartilage tissue. Chondrocyte marker genes were examined using cells from only 4 patients, because we obtained enough cells in only 4 patients. The relative expression levels of aggrecan, type II, Sox 9 were 2.61, 4.03, and 1.71, respectively. Three-dimensional cultured cartilage from all 6 displaced fragments contained 62.0 pg/cell (range, 22.8-91.3 pg/cell) of glycosaminoglycan and expressed type II collagen in the superficial and middle layer. CONCLUSIONS The chondrocytes obtained from the displaced fragments remained viable and exhibited chondrogenic features. These cells may potentially be a cell source of autologous chondrocytes implantation. CLINICAL RELEVANCE We have shown that displaced fragments from OCD of the elbow have potential for a cell source for generating 3-dimensional cultured cartilage.

Abstract
BACKGROUND Bone peg grafting (BPG) has been advocated for early-stage humeral capitellar osteochondritis dissecans (COCD). However, the clinical and radiological results of BPG, along with its indications, have not been described in detail. HYPOTHESIS COCD classified as International Cartilage Repair Society (ICRS) osteochondritis dissecans (OCD) I or II in adolescent baseball players can be treated successfully by BPG. STUDY DESIGN Case series; Level of evidence, 4 METHODS: Eleven male baseball players (age range at surgery, 13-16 years) who underwent BPG for COCD were enrolled in this study. No improvement had been seen in any patient after 6 months of preoperative nonthrowing observation. During surgery, 2 to 5 bone pegs were inserted into the COCD lesion after confirmation of lesion stability to the bony floor. All patients were directly evaluated at 12 and 24 months after surgery by physical findings, radiological prognosis, and magnetic resonance imaging (MRI). RESULTS Of the 11 patients, 10 could return to comparable baseball ability levels within 12 months. The Timmerman-Andrews score improved significantly from a mean ± SD of 171.8 ± 12.1 preoperatively to 192.3 ± 6.5 at the final observation. Radiological healing of the lesions was determined as complete in 8 patients and partial in 3. Patients possessing a centrally positioned lesion or a lesion <75% of the size of the capitellum tended most strongly to achieve complete radiological healing, while growth plate status appeared unrelated to outcome. The mean Henderson MRI score improved from 6.3 ± 1.5 to 4.8 ± 1.6 at 12 and 24 months after BPG, respectively. MRI findings also suggested that remodeling of COCD lesions had continued to up to 24 months postoperatively. CONCLUSION BPG enabled 91% of COCD patients with ICRS OCD I or II to return to preoperative baseball abilities within 12 months. Integration of the grafted site may continue until at least 24 months postoperatively. An ICRS OCD I or II lesion with central positioning and/or occupying <75% of the size of the capitellum in the coronal plane is a good indication for BPG.

Abstract
Osteochondritis dissecans (OCD) is a disorder of articular cartilage and subchondral bone. In the elbow, an OCD is localized most commonly at the humeral capitellum. Teenagers engaged in sports that involve repetitive stress on the elbow are at risk. A high index of suspicion is warranted to prevent delay in the diagnosis. Plain radiographs may disclose the lesion but computed tomography and magnetic resonance imaging are more accurate in the detection of OCD. To determine the best treatment option it is important to differentiate between stable and unstable OCD lesions. Stable lesions can be initially treated nonoperatively with elbow rest or activity modification and physical therapy. Unstable lesions and stable lesions not responding to conservative therapy require a surgical approach. Arthroscopic debridement and microfracturing has become the standard initial procedure for treatment of capitellar OCD. Numerous other surgical options have been reported, including internal fixation of large fragments and osteochondral autograft transfer. The aim of this article is to provide a current concepts review of the etiology, clinical presentation, diagnosis, treatment, and outcomes of elbow OCD.

Abstract
BACKGROUND Limited data exist regarding the indications and expected outcomes of internal fixation of unstable in situ osteochondritis dissecans (OCD) lesions of the capitellum. The objective of this investigation was to characterize healing rates, clinical results, and functional outcomes of internal fixation of unstable in situ OCD lesions in adolescents. METHODS Retrospective analysis was performed of 26 elbows in 24 patients who underwent internal fixation for unstable in situ OCD. Mean age at surgery was 14.1 years; 7 patients had open physes. Mean lesion width and thickness were 12.0 and 5.4 mm, respectively. Demographic, clinical, and radiographic variables of patients who went on to healing versus revision procedures were compared with univariate analysis. Classification and regression tree analysis identified optimal threshold values associated with healing. Functional outcomes were assessed with the Mayo Elbow Performance Score, Timmerman, and Pediatric Outcomes Data Collection Instrument scores. Mean clinical follow-up was 39 months (range, 12 to 96 mo). RESULTS Twenty of 26 elbows healed. Patients who healed were younger (P=0.01) and had smaller sagittal plane lesion widths (P=0.03) than patients who underwent revision. Classification and regression tree analysis identified 15.3 years and 13 mm as the threshold values distinguishing patients who did and did not heal. Overall, mean arc of elbow motion improved from 109 degrees preoperatively to 127 degrees at last follow-up (P=0.001). Mean Mayo Elbow Performance Score improved from 68 to 92 (P<0.001). Of 18 questionnaire respondents, two thirds reported full return to their prior level of sports participation without elbow complaint; 9 had excellent final Timmerman scores, 5 good, and 4 fair. Mean Pediatric Outcomes Data Collection Instrument upper extremity and sports scores were 98 and 93, respectively. CONCLUSIONS Healing, return to sports, and good to excellent functional outcomes may be expected in the majority of patients undergoing internal fixation of unstable in situ OCD lesions of the capitellum, particularly in younger patients with lesions <13 mm in sagittal width. Higher levels of evidence must further differentiate the optimal surgical treatments of unstable OCD. LEVEL OF EVIDENCE Level IV.

Abstract
Background: Despite pitch count limits, the incidence of Little League elbow is increasing. A risk-evaluation tool capable of predicting which players are predisposed to throwing injury could potentially prevent injuries. Purpose: To investigate the effectiveness of a risk factor checklist for predicting elbow injury in Little League baseball players during 1 season. The hypothesis was that a preseason risk-evaluation checklist could predict which players were predisposed to elbow injury. Study Design: Case-control study; Level of evidence, 3. Methods: A preseason risk-evaluation checklist was distributed to Little League baseball teams in Japan. Six months later, a follow-up questionnaire was mailed to determine injuries sustained during the season. Logistic regression analysis was performed, assigning presence or absence of elbow injury during the season as the dependent variable, and an injury risk score (IRS) was developed based on the statistically significant variables. Receiver operating characteristic (ROC) curve analysis was conducted to determine the predictive validity of the checklist and the optimal cutoff IRS. Results: Data from 389 Little League players were analyzed. Among them, 53 players experienced an elbow injury requiring medical treatment during the season. Six checklist items associated with a medical history of throwing injury, pitch volume, and arm fatigue were found to be significant. Responses to the items could predict the players who were susceptible to injury during the season, with a two-thirds cutoff value for a 6-item checklist (area under the curve, 0.810; sensitivity, 0.717; specificity, 0.771). Conclusion: Results from a 6-item preseason checklist can predict which Little League players are to sustain an elbow injury by the end of the season. Clinical Relevance: The ability to predict which Little League baseball players are predisposed to elbow injury allows parents and coaches to initiate preventive measures in those players prior to and during the baseball season, which could lead to fewer elbow injuries.

Abstract
BACKGROUND Advanced-stage osteochondritis dissecans of the capitellum affecting the lateral wall may result in osteoarthritis, and suitable treatment is needed to avoid permanent deformation and impaired function. We aimed to assess postoperative outcomes of costal osteochondral autograft for treatment of this condition. METHODS We included 22 young overhead athletes (mean age, 13.9 years) with advanced osteochondritis dissecans of the humeral capitellum who underwent costal osteochondral autograft. All patients had elbow pain and wide-range articular cartilage lesions. We evaluated clinical and radiographic outcomes at a mean follow-up of 27 months (range, 12-77 months). RESULTS All patients achieved rapid functional improvement and returned to their former sports activity levels. The baseball players were able to play catch within 62 to 164 days (mean, 107 days) and returned to full pitching activity within 123 to 339 days (mean, 226 days). We assessed mean elbow function by the clinical rating system of Timmerman and Andrews and the Japanese Orthopaedic Association sports score; the scores improved from 121.5 and 53.7 points preoperatively to 169.2 points and 86.1 points, respectively, at the time of follow-up. Four patients required additional minor surgical procedures, including screw removal, loose body removal, and shaving off of spur formation. No patient showed obvious radiographic changes of osteoarthritis. All patients were satisfied with the final outcomes and had good functional recovery. CONCLUSION Costal osteochondral autograft gave satisfactory results for advanced osteochondritis dissecans of the humeral capitellum with extensive lesions affecting the lateral wall.

Abstract
Pediatric overuse injury is a common complaint presenting to pediatricians. Overuse injury can affect the soft tissues or bone, and results from an imbalance between training and load to the tissues and recovery time. In the skeletally immature athlete, physeal and apophyseal tissue is particularly vulnerable to overuse resulting in different patterns of injury compared to adults. Awareness of age-dependent patterns of overuse is necessary for proper recognition, treatment, and prevention of injury. This article reviews the most common pediatric overuse injuries with emphasis on risk factors, diagnosis, and treatment. Guidelines for prevention are included, as this is the key component for successful management of overuse injury in pediatric athletes.

Abstract
BACKGROUND The prevalence and clinical characteristics of osteochondritis dissecans (OCD) of the humeral capitellum among adolescent baseball players are unknown. PURPOSE To determine the OCD prevalence in adolescent competitive baseball players and to investigate the clinical characteristics of these patients. STUDY DESIGN Cross-sectional and case-control study; Level of evidence, 3. METHODS A total of 2433 baseball players (mean age, 14.5 ± 1.5 years) belonging to junior high school and high school baseball clubs were enrolled. Players completed a questionnaire, and the elbow of each player's throwing arm was assessed by ultrasonography. Participants with abnormal results on ultrasonography were further examined through radiographic study. The OCD lesions were classified into stages based on radiographic results, and demographic data were compared between players with and without OCD lesions. RESULTS Osteochondritis dissecans of the humeral capitellum was found in 82 (3.4%) elbows by ultrasonography. Players with an OCD lesion began playing baseball at an earlier age (P = .016), had a longer duration of competitive play (P = .0013), and had experienced more present (P = .0025) and past (P < .0001) elbow pain compared with players without a lesion. There were no differences between the 2 groups in the position played (P = .26). Sixty-eight patients underwent further radiographic examination for OCD (radiography, computed tomography, magnetic resonance imaging). Of these players, 10 (14.7%) were classified as having stage I OCD (radiolucent stage); 26 (38.2%), stage II (fragmentation stage); 9 (13.2%), stage III (loose body stage); 9 (13.2%), stage IV (residual stage); and 14 (23.5%), stage V (postoperative stage). CONCLUSION The prevalence of OCD of the humeral capitellum, including latent cases, was 3.4% among adolescent baseball players. Players with OCD lesions began playing baseball at earlier ages, had played for longer periods, and had experienced more elbow pain. The player's current baseball position may not be related to the existence of OCD lesions in adolescents.

Abstract
BACKGROUND Treatment for capitellar osteochondritis dissecans (COCD) lesions is usually based on their stability from the bony floor after arthroscopic or open direct observation. Thus, a noninvasive means of lesion stability assessment by use of imaging is desirable to preoperatively determine treatment strategy. PURPOSE To evaluate our modified MRI staging system for COCD, we compared the results of MRI staging with the International Cartilage Repair Society (ICRS) classification for lesion stability. Intra- and interrater reliability for MRI staging was examined as well. STUDY DESIGN Cohort study (diagnosis); Level of evidence, 2. METHODS Fifty-two COCD lesions were preoperatively evaluated by T2-weighted MRI and classified into 5 stages: stage 1 = normally shaped capitellum with several spotted areas of high signal intensity that is lower than that of cartilage; stage 2 = as with stage 1 but with several spotted areas of higher intensity than that of cartilage; stage 3 = as with stage 2 but with both discontinuity and noncircularity of the chondral surface signal of the capitellum and no high signal interface apparent between the lesion and the floor; stage 4 = lesion separated by a high intensity line in comparison with cartilage; and stage 5 = capitellar lesion displaced from the floor or defect of the capitellar lesion noted. The MRI staging results were compared with the intraoperative ICRS classification for lesion stability of each patient. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were all determined for fragment instability. Intra- and interrater correlations for our MRI staging were calculated among 3 examiners. RESULTS Preoperative MRI grading correctly matched ICRS classification in 49 of 52 patients (94%), with a sensitivity of 100% and a specificity of 80%. The PPV and NPV were 93% and 100%, respectively, for diagnosing lesion instability. Intrarater reliability (intraclass correlation coefficient [ICC]) for MRI staging was high at ICC(1, 1) = 0.86 and ICC(1, 2) = 0.90, as was interrater reliability at ICC(2, 1) = 0.82 and ICC(2, 3) = 0.88. CONCLUSION The MRI staging system provides accurate and reliable evidence for estimating ICRS classification and instability of COCD and is useful to decide appropriate treatment.

Abstract
We present the case of a 27-year-old female with subcortical osteonecrosis of the humeral capitulum. Percutaneous retrograde drilling of the lesion and application of recombinant human bone morphogenetic protein (BMP)-7 were combined with autologous bone grafting. At follow-up the patient was almost pain-free, had normalized her range of motion, and radiography showed consolidation of the lesion without any heterotopic bone formation. By timing surgery prior to subchondral collapse, biomechanical stability of the subchondral bone was maintained. To our knowledge, this is the first report on the treatment of an osteonecrosis in this location with a BMP, and this strategy could potentially be applied in other locations with juxta-articular osteonecrosis.

Abstract
Elbow pain in pediatric throwing athletes can be very concerning and challenging to diagnose. Diagnosis involves determining whether the injury is chronic or acute in nature and the anatomical location of the pain. Physicians should be aware of the sport-specific forces that predispose athletes with immature skeletons to injury and should be familiar with the common presentations of these injuries. In order to narrow the diagnosis, physicians should gather a detailed history of how and when the pain occurred in addition to performing a thorough physical exam that includes tests, such as the modified milking maneuver and the moving valgus stress test. Appropriate imaging helps physicians to confirm the diagnosis and elucidates any associated pathology in patients. In most cases, the treatment given to patients is conservative and involves rest, ice, non-steroidal anti-inflammatory drugs for pain, and an appropriate physical therapy regimen with a progressive return to play when symptoms have resolved. When patients fail to respond to conservative treatment, surgical intervention may be needed. Knowing when to refer patients for orthopedic evaluation helps athletes return to play quickly and safely.

Abstract
We report on 2 cases of hyperextension/valgus elbow injuries in two adult male national team water polo goalkeepers. Both were healthy and had never sustained any major injuries of the elbow. Mechanism and type of injury in both of them was identical. Different medical treatment protocols of these injuries possibly have led to different outcomes, with one of them developing osteochondritis dissecans (OCD). Inadequate medical treatment of acute impact elbow injuries could lead to osteochondritis disecans of the elbow in top-level adult male water polo goalkeepers.

Abstract
BACKGROUND Osteochondritis dissecans (OCD) of the elbow is a problematic condition that affects a fair number of young athletes. One treatment option is the use of osteochondral autografts, which are commonly taken from donor sites on the less weightbearing surfaces of the knee. PURPOSE To use magnetic resonance imaging (MRI) to assess the cartilage depths of sites in the knee and elbow that are commonly used as donor and recipient sites to optimize depth matching for osteochondral autograft procedures. STUDY DESIGN Descriptive laboratory study. METHODS All knee and elbow MRI scans acquired from 3-T machines in patients aged 16 to 25 years within a single hospital system were reviewed. Studies were excluded if there had been previous surgery on the joint or if there were significant chondral defects in the areas to be measured. All cartilage depth measurements were independently performed by 3 different physicians to the nearest 0.01 mm. At the elbow, 6 locations on the capitellum and 2 on the trochlea were chosen. At the knee, 4 locations along the anterior-lateral femoral condyle, 5 surrounding the intercondylar notch, and 1 on both the medial- and lateral-posterior femoral condyles were chosen. RESULTS There were 111 knee MRI (74 male, 37 female) and 94 elbow MRI (85 male, 9 female) scans that met all inclusion criteria. The average cartilage depths from each investigator were then averaged to provide an overall mean depth at each location. All average cartilage depths within the knee were thicker than those in the elbow, where the averaged mean thickness of all the 8 measured sites was 1.27 mm (range, 0.78-1.63 mm). Within the knee, the thinnest areas of cartilage, and therefore closest matches, were discovered at the posterior pole of the medial femoral condyle (mean ± SD, 1.95 ± 0.46 mm) and at the distal-most anterior-lateral femoral condyle (1.85 ± 0.46 mm). The average variance between the mean cartilage depths measured by each investigator for each location was 0.12 mm in the elbow and 0.22 mm in the knee. CONCLUSION Average cartilage depths in the knee were thicker than those in the elbow at all sites measured. The thinnest areas in the knee were the posterior aspect of the medial femoral condyle and the distal-most aspect of the anterior-lateral femoral condyle. CLINICAL RELEVANCE This study provides the surgeon with meaningful data on average cartilage depths at common donor sites in the knee and recipient sites in the elbow.

Abstract
BACKGROUND The stability of an osteochondritis dissecans (OCD) lesion of the humeral capitellum may be determined by intraoperative probing with unstable lesions being displaceable. Although preoperative imaging is used to diagnose and determine treatment of these lesions, it is unclear whether unstable lesions on imaging correspond to those found intraoperatively. QUESTIONS/PURPOSES We therefore examined the concordance between preoperative imaging and intraoperative instability and examined the imaging features of the patients who healed without surgery. METHODS We retrospectively reviewed 61 patients who underwent OCD of the humeral capitellum surgery or nonoperative treatment. All patients had plain radiography, MRI, and/or CT scans. The presence or absence of stability was determined intraoperatively by the International Cartilage Repair Society OCD classification. We determined the sensitivity, specificity, and predictive value of various imaging findings to predict instability. RESULTS The following preoperative imaging features were associated with intraoperative instability: a displaced fragment, epiphyseal closure of the capitellum, or a lateral epicondyle observed on radiographs; irregular contours of the articular surface or a high signal interface on T2-weighted MRI; and a displaced fragment observed on CT. Unstable lesions were more common when the epiphysis of the capitellum was closed. Intralesional segmentation was sensitive for detecting an unstable lesion, whereas displaced type on the radiographs and displaced fragment on the CT were specific. The following imaging findings were not seen in nonoperative patients: displaced type and closure of the epiphyseal line on radiographs, irregular contours of the articular surface, articular defects, and T2 high signal intensity interface between the fragments and their bed on the MRI or a displaced fragment on the CT. CONCLUSIONS Although we found high sensitivity for some preoperative findings on imaging, none reached 100% of sensitivity. Preoperative MRI related to the intraoperative assessment of stability. LEVEL OF EVIDENCE Level III, diagnostic study. See Guidelines for Authors for a complete description of levels of evidence.

Abstract
Elbow injuries in young athletes are increasing with these athletes specializing in a single sport at an early age and participating in their chosen sport at a high level year-round. The majority of these injuries occur from valgus loading of the elbow, either repetitively causing an overuse injury or more acutely resulting in a fracture or dislocation. Capitellar osteochondritis dissecans, medial epicondyle injuries and ulnar collateral ligament injuries are three of the most common elbow injuries occurring in young athletes.

Abstract
The overhead throwing motion is a complex sequence of maneuvers that requires coordinated muscle activity in the upper and lower extremities. The shoulder and elbow are subject to multidirectional forces and are particularly vulnerable to injury during specific phases of the overhead throwing motion. Ligamentous, tendinous, neural, and osseous pathology that may occur in the shoulder or elbow of an overhead-throwing athlete will be discussed, with an emphasis on the role of MR imaging and MR arthrography.

Abstract
Osteochondritis dissecans (OCD) of the humeral capitellum is a disorder affecting mainly boys between the ages of 12 and 15 years. The exact etiology of OCD is not clear, but it is believed that repetitive trauma is the primary cause. Genetic factors are thought to play a secondary role in the pathogenesis. We present 17-year-old identical twins with similar MRI and arthroscopic findings, suggesting that genetic components are involved in the etiology of OCD of the humeral capitellum.

Abstract
BACKGROUND The purpose of this study was to evaluate the clinical outcomes of mosaicplasty in the treatment of osteochondritis dissecans of the distal humeral capitellum. MATERIALS AND METHODS Between 2003 and 2007, 10 patients (6 female and 4 male patients), with a mean age at surgery of 18 years (range, 13 to 27 years), with advanced lesions of capitellar osteochondritis dissecans underwent mosaicplasties. The surgical technique involves transplanting small-sized cylindrical osteochondral grafts from the lateral periphery of the femoral condyle at the level of the patellofemoral joint to the defect of the capitellum. At a mean follow-up of 30 months, all elbows were assessed with the Mayo Elbow Performance Score and a modified functional elbow score (Constant). RESULTS Postoperative radiographs and control magnetic resonance imaging/computed tomography images showed incorporation of the subchondral cortex in all patients. All but 2 patients were completely pain free after surgery. Of the patients, 8 (80%) had no reduction in range of motion. By use of the Mayo Elbow Performance Score, the injured elbow had a preoperative mean score of 71 points (range, 55 to 85 points) and increased significantly to a mean score of 93.5 points (range, 85 to 100 points) postoperatively (P = .0005, paired t test). The nonoperative elbows had a mean score of 100 points, whereas the operated elbows had a mean score of 93.5 points. The functional elbow score showed a mean difference of 7.5 points between the operated and nonoperative elbows. No infection or neurologic deficit developed after surgery in any case. CONCLUSIONS Autologous osteochondral mosaicplasty for advanced lesions of capitellar osteochondritis dissecans can provide satisfactory clinical and radiographic results.

Abstract
Osteochondritis dissecans (OCD) of the humeral capitellum most commonly affects young athletes engaged in sports that repetitively stress the elbow. It is characterized by localized injury of subchondral bone of the humeral capitellum. To determine the best treatment option for OCD in young athletes, it is important to differentiate between stable and unstable OCD lesions. Stable lesions can be treated with rest, whereas unstable lesions, as well stable lesions that do not respond to conservative therapy, may require a surgical approach. Magnetic resonance imaging is the diagnostic study of choice to evaluate capitellar OCD lesions and loose bodies and to accurately determine the stability and viability of the OCD fragment. A variety of surgical approaches have been reported, from internal fixation of large fragments to autologous chondrocyte grafts. Arthroscopic surgery is becoming the standard treatment of capitellar OCD. This minimally invasive approach shows good results, a low risk of operative morbidity, and early recuperation postoperatively. The distal ulnar portal we describe here allows for ergonomic exposure to the posterolateral capitellum, providing easier access for drilling, burring, and local debridement of lesions amenable to arthroscopy.
