Comparative Outcomes of Early, Elective, and Delayed Treatment for Lateral Condyle Fracture of the Humerus in Children: A Retrospective Study from a Single Center in Turkey (2013-2021).

BACKGROUND Lateral condyle fracture of the humerus in children should be diagnosed and treated quickly to avoid the complications of malunion and varus deformity of the elbow. Worldwide, pediatric orthopedic departments experienced delays in patient diagnosis and treatment during the COVID-19 pandemic. This retrospective study from a single center in Turkey aimed to compare outcomes from early treatment, elective treatment, and delayed treatment in 140 children with lateral condyle fracture of the humerus between 2013 and 2021. MATERIAL AND METHODS In the study, 140 patients with Milch type 2 fractures were included. Patients underwent fixation with K-wires or screws after open or closed reduction. Data collected included age, sex, trauma details, surgery timing, operating conditions, perioperative issues, and rehabilitation outcomes. Fracture union and complications were monitored through clinical examinations and X-rays. Clinical outcomes were evaluated using the Mayo Elbow Performance Score (MEPS). RESULTS There were 58 patients in the early group, 52 in the elective group, and 30 in the delayed group. Surgery durations varied among the groups (P=0.000). The early and delayed groups as well as the early and elective groups had significantly different incision sizes (P=0.000 for both). The early and delayed groups and the early and elective groups had significantly different MEPS scores (P=0.002 and P=0.011, respectively). CONCLUSIONS In patients with late-presenting lateral condyle fractures, although complications increase, surgical treatment does not yield worse outcomes. Standardization of fracture management should be maintained during periods such as COVID-19.

Predictive factors for the development of Gartland type IV supracondylar humerus fractures: a prospective clinical study.

OBJECTIVE: This study aimed to identify the preoperative predictive factors for the development of Gartland type IV supracondylar humerus fracture based on the patient characteristic, fracture mechanism, and preoperative radiographic fracture characteristics. METHODS: This prospective study included the data of 120 patients with Gartland type III and IV supracondylar humerus fractures treated in a single center from 2020 to 2021. Patients' age, gender, height/weight percentile values, injury mechanisms, the proximity of fracture fragment to the skin (i.e., dimple sign), and time from trauma to surgical treatment were recorded. In the preoperative radiographs, the degree of extension or flexion deformity between fracture fragments in the sagittal plane, varus/valgus angulation between fracture fragments in the coronal plane, the amount of translation (medial or lateral) in the coronal plane, and the amount of osseous apposition between fracture fragments in the coronal plane were evaluated. With the authors' consensus, the patients were divided into 2 groups based on the presence of multidirectional instability during the intraoperative reduction: group 1 (Gartland type III; 99 patients) and group 2 (Gartland type IV; 21 patients). Fixation of the fractures was then completed. RESULTS: Significant differences were observed between groups in the valgus/varus angle and amount of osseous apposition (P < .001). Although no significant difference was found in terms of translation amount between the groups (P=.088), there was a significant correlation with medial translation in type IV fractures (P < .001). The correlation between the results and the groups was checked with Spearman's test. Medial translation (r=0.352), varus or valgus angulation (r=0.616), and osseous apposition (r=0.433) exhibited a positive correlation. The probability of type IV fracture was modeled for the preoperative parameters using binary logistic regression. The regression analysis showed that the diagnosis of type IV supracondylar fractures could be predicted, if varus or valgus angulation was more than 25.5° (81% sensitivity, 85% specificity, odds ratio=1.725; 95% CI=1.170-2.541, P=.001, r=0.616) and if the amount of osseous apposition was more than 9.5 mm (85% sensitivity, 81% specificity, odds ratio=1.471; 95% CI=0.714-3.029, P=.001, r=0.433) in the preoperative radiographs. There was also a significant correlation between medial translation (varus angulation) (P < .001, r=0.352), age (P=.019, r=0.255), and patients with more than 90 height/weight percentile values (P < .001, r=0.508) with the possibility to have Gartland type IV fractures. CONCLUSION: This study has found some preoperative factors that may be relevant for type IV Gartland fractures. Height/weight values greater than the 90 percentile, varus or valgus angulation greater than 25.5°, bone apposition values greater than 9.5mm, medial translation values greater than 11mm, and older than eight years patients type IV fractures were more common in such patients. If surgeons can more accurately diagnose a Gartland type IV fracture preoperatively, the surgeon can more accurately inform the patient and plan better treatment. LEVEL OF EVIDENCE: Level II, Diagnostic Study.

A technical trick for extracting a stingray spine from hand: a case report.

Injuries from stingray fish are among the most common fish stings, and their frequency is increasing with the increase in global tourism. It most commonly causes injuries to the extremities and causes morbidity if not treated appropriately. Less commonly, life-threatening injuries can be observed due to injuries in the thorax and abdomen and damage to large vessels and vital organs. In addition to severe pain, tissue necrosis, and secondary infection after injury, systemic symptoms may occur. Since these injuries can occur in both fresh and salt water, it is possible to encounter such a case at any time. Flat spines are sharp, with backward barbs or serrations that make them difficult to extract once they penetrate tissue. After first aid, surgical extraction of the stingray spine with minimal damage is essential in addition to local and systemic treatments. In the literature, there are studies on envenomation and other systemic findings after stingray spine injuries, but few publications are available on the stingray spine extracted technique after injury. This case report presents a new and helpful technique for stingray spine extraction.

Can American Orthopaedic Foot and Ankle Society (AOFAS) score prevent unnecessary MRI in isolated ankle ligament injuries?

INTRODUCTION AND OBJECTIVE: Ankle injuries are the most common musculoskeletal injuries. Its incidence is also high among sports injuries. Direct X-ray, ultrasound and MRI can be requested after the history and physical examination in the patient who presents with ankle ligament injury. Some classifications are used for requesting direct X-ray after ankle injury. Since clear limits are not specified in the literature for MRI, the rate of unnecessary MRI examinations is high. We argue that the decision can be made according to the AOFAS score to be checked before MR is requested, and thus unnecessary MR requests can be reduced. MATERIAL AND METHOD: Ankle MRI images of patients who underwent ankle MRI due to ankle trauma between January 2018 and December 2020 were scanned. 328 patients who met the criteria were included in the study. Patients with AOFAS scores in their outpatient clinic records were identified. AOFAS scores of patients with at least one ligament injury and those with normal MR images were statistically compared. Sensitivity and specificity were determined for the AOFAS score using ROC analysis. RESULTS: Patients with ligament damage as a result of MRI examination were 21.3% (n=70), and patients without any ligament damage were 78.7% (n=258). There was a statistically significant difference in terms of AOFAS between the group with ligament damage and the group without ligament damage (p< 0.05). In the ROC analysis, the AOFAS threshold value for MR request was determined as 80.5 (84.3% sensitivity and 72.3% specificity). Based on the determined threshold value, 73 patients who had unnecessary MRI would have been eliminated, thus reducing the number of MRIs by 42.6%. CONCLUSION: The AOFAS scores of patients with ligament damage were statistically significantly lower than those of patients without ligament pathology. Unnecessary MRI can be significantly prevented by using the AOFAS score in ankle traumas without bone fractures.

Can formation of avascular necrosis really be prevented in Delbet type 2 femoral neck fractures?

BACKGROUND: Fractures of proximal femur are rarely seen in childhood. These fractures can result in serious complications such as avascular necrosis (AVN), coxa vara, and early closure of the femoral epiphysis. The aim of this study is to investigate retrospectively the Delbet type 2 fractures that are commonly seen and has high rates of AVN. METHODS: Forty-two patients whose Delbet type 2 fractures were treated in our hospital between January 2009 and June 2018 were analyzed. The patients' mechanism of fracture formation, displacement of the fracture, presence of accompanying injuries, timing of surgery, open or closed reduction, whether the screws cross the epiphyseal growth plate epiphyseal line, and AVN data were analyzed retrospectively. RESULTS: Of the 42 screened patients, 34 patients with complete follow-up graphs and files were included in the study. The mean age of the patients was 11.02 years (1-17 years old), and the mean follow-up time was 40.82 months (range 24 to 98 months). When the follow-up radiographs of the patients were examined, it was found that AVN in 9 patients (26.5%), coxa vara in 2 patients (5.9%), and non-union in 1 patient (2.9%). The AVN rate was significantly higher in patients with high-energy injuries and high fracture displacement at baseline (p=0.034 and p=0.047, respectively). CONCLUSION: According to our findings in Delbet type 2 fractures, other than the severity of the trauma and the initial displacement of the fracture, factors related to the treatment process do not have a significant effect on the development of AVN. Age was not determined as a risk factor for the development of AVN in these patients.

Periprosthetic infection risks and predictive value of C-reactive protein / albumin ratio for total joint arthroplasty.

BACKGROUND AND AIM: There are no gold standard markers to estimate the risk of developing periprosthetic infections. Our aim is to compare the risks of periprosthetic infection in patients with THA and THA and to investigate the predictive significance of the CRP / albumin ratio. METHODS: This is a retrospective study containing data from 241 osteoarthritis patients and 19 patients with periprosthetic infections who underwent TKA and THA in our hospital from January 2014 to January 2019.12 risk factors(CRP/ albumin, albumin, CRP, age, gender, BMI, DM, ASA, nasal culture, urine culture, hospital stay, operation time) were analyzed. RESULTS: In the binary logistic regression model and multivariate regression analysis, the rate of CRP / albumin was 17.161 times higher than the patients with ≤0.16 cut-off value. (CRP / albumin ratio (odds ratio (OR) = 17.16, 95% CI: 1.55-189.03, P: 0.02). High BMI increased the risk of periprosthetic infection 1.3 times. Nasal bacterial colonization (OR = 0.99, 95% CI: 0.868-1.38, P: 0.7) and bacterium in urine (OR = 0.502, 95% CI: 0.07-3.598, P: 0.703) did not pose a significant risk for periprosthetic infection. CONCLUSION: According to our findings, the CRP / albumin ratio has a more prognostic capacity than other risks in determining the risk of periprosthetic infection for total joint arthroplasty. CRP / albumin ratio is a cheap and easy to apply marker. Routine urine and nasal bacteria screening is not required before total joint arthroplasty.

Neglected volar subluxation of the metacarpophalangeal joint of the thumb: A case report.

We present an 30 year-old female patient with a volar subluxation of the metacarpophalangeal joint of the thumb.Dislocation  of the metacarpophalangeal joint is rare ; volar subluxation is much more rare. Open reduction was performed through a dorsal incision because of the soft tissue interposition. Ultimately, doctors in the emergency department should pay attention to volar MCPJ subluxation and it is important to assess collateral ligament stability after closed reduction.

Changes in Composition of ADAMTS-5 and CD-68 in the Knee Joint Synovial Fluid Cells of Meniscal Tears Patients an Immunohistochemical Study / Cambios en la Composición de ADAMTS-5 y CD-68 en las Células del Líquido Sinovial de la Articulación de la Rodilla en Pacientes con Desgarro de Menisco. Un Estudio Inmunohistoquímico

SUMMARY: Meniscus tear is an important injury affecting the quality of life. This work is aimed to investigate the activity of CD68 and ADAMTS-5 in cells in synovial fluid in male and female patients with meniscal tear. In this study ,18 male and 22 female patients with meniscal tears were included. Local pain sensation during patients' physical examination, swelling, performing daily activities and difficulty in running-walking complaints were determined. 5 cc synovial fluids were aspirated from the lateral suprapatellar pouch part of the knees with meniscal pain. After routine histological follow-up of the samples, they were embedded in paraffin and sectioned with microtome and 5 micrometer thickness. CD68 and ADAMTS-5 primary antibodies were used for immunohistochemical analysis. Sections were taken and evaluated with a stylish microscope. The distribution of blood cells after meniscus tear was higher in female patients than in male patients. CD68 distribution in female patients appeared higher than in male patients. CD68 expression was high in macrophage cell cytoplasm. ADAMTS-5 expression was higher in female patients in degenerative cells and apoptotic cells. ADAMTS-5 is an important metallo-protein involved in the development of apoptotic signal and extracellular matrix synthesis in patients with ADAMTS-5 meniscus tear, and it may be an important criterion for the treatment developed after injury. CD68 and ADAMTS-5 activity was thought to be one of the important signal pathways that can be identified in the treatment of meniscus tear.

RESUMEN: La rotura del menisco es una lesión importante que afecta la calidad de vida. El objetivo fue investigar la actividad de CD68 y ADAMTS-5 en células del líquido sinovial en pacientes masculinos y femeninos con desgarro meniscal. Se incluyeron 18 pacientes masculinos y 22 femeninos con desgarros meniscales. Se determinó la sensación de dolor local durante el examen físico de los pacientes, la hinchazón, la realización de actividades diarias y la dificultad al correr y caminar. Se aspiraron 5 cc de líquido sinoviale de la parte de la bolsa suprapatelar lateral de las rodillas de los pacientes con dolor meniscal. Después del seguimiento histológico de rutina, las muestras se incluyeron en parafina y se seccionaron con un micrótomo de grosor de 5 micrómetros. Para el análisis inmunohistoquímico se usaron los anticuerpos primarios CD68 y ADAMTS-5. La distribución de las células sanguíneas después del desgarro del menisco fue mayor en pacientes femeninos que en pacientes masculinos. La distribución de CD68 en pacientes femeninos fue más alta que en pacientes masculinos. Además la expresión de CD68 fue alta en el citoplasma de los macrófagos. La expresión de ADAMTS-5 fue mayor en pacientes femeninos en las células degenerativas y células apoptóticas. ADAMTS-5 es una metaloproteína importante en el desarrollo de la señal apoptótica y la síntesis de matriz extracelular en pacientes con rotura de menisco ADAMTS-5, y puede ser un criterio importante para el tratamiento después de la lesión. La actividad de CD68 y ADAMTS-5 era una de las vías de señal importantes que se pueden identificar en el tratamiento de la rotura del menisco.

Graft application and dexamethasone treatment influences new bone formation in rat tibial bone defects / Aplicación de injerto y tratamiento con dexametasona influyen en la formación de hueso nuevo en los defectos en la tibia de rata

SUMMARY: The objective of this study were bone defect complications that occur due to traumas or infections. Bone grafts are required to provide support, fill gaps and improve biological repair in skeletal damage. Dexamethasone plays role in calcium signaling modulation and used in diseases. Aim of this study was to evaluate osteonectin and osteopontin expressions in new bone development after dexamethasone application on tibial bone defects. Rats were divided into defect, defect+graft and defect+graft+dexamethasone treated groups. Tibial bone defect created, and rats were kept immobile for 28 days. Alloplastic material was placed in defect area in second and group third groups. 2.5 mg/kg Dex and normal saline were injected to dexamethasone and defect groups twice a week for 56 days. Inflammation and congestion were increased in defect and defect+graft groups. Defect+graft+dexamethasone group; increased number of osteoblast and osteocyte cells, dense bone matrix, formation of new bone trabeculae was observed. Defect+graft group; osteonectin expression in graft regions, osteoblast cells, some connective tissue cells and fibers were seen whereas in defect+graft+dexamethasone group; osteopontin expression in osteoblast and osteocyte cells of new bone trabeculae were observed. Dexamethasone may lead to formation of new bone trabeculae into the graft material resulting in increased osteoconduction and osteoinductive effect for differentiation of osteon.

RESUMEN: Los defectos óseos son complicaciones que ocurren debido a traumas o infecciones. Se requieren injertos óseos para proporcionar apoyo, llenar los espacios y mejorar la reparación biológica en el hueso dañado. La dexametasona desempeña un papel importante en la modulación de la señalización del calcio y se usa en enfermedades. El objetivo de este estudio fue evaluar las expresiones de osteonectina y osteopontina en el desarrollo óseo después de la aplicación de dexametasona en defectos óseos tibiales. Las ratas se dividieron en grupos: defecto, defecto + injerto y defecto + injerto + grupos tratados con dexametasona. Se creó un defecto óseo tibial, y las ratas se mantuvieron inmóviles durante 28 días. El material aloplástico se colocó en el área del defecto en el segundo y tercer grupo. Se inyectaron 2,5 mg / kg de dexametasona y solución salina normal a grupos de defectos dos veces por semana durante 56 días. La inflamación y la congestión aumentaron en los grupos de defectos y defectos + injerto; En el grupo defecto + injerto + grupo tratado con dexametasona se observó un aumento en el número de osteoblastos y osteocitos, de matriz ósea densa y en la formación de nuevas trabéculas óseas. En el grupo defecto + grupo de injerto se observó la expresión de osteonectina en las áreas de injerto, osteoblastos, algunas células y fibras de tejido conectivo, mientras que en el grupo defecto + injerto + dexametasona se observó la expresión de osteopontina en osteoblastos y osteocitos y formación de nuevas trabéculas óseas . En conclusión la dexametasona puede conducir a la formación de nuevas trabéculas óseas en el material de injerto, lo que resulta en un aumento de la osteoconducción y un efecto osteoinductivo para la diferenciación del osteón.

Mid-term outcomes of surgical treatment in fractures in patients with osteopetrosis.

AIMS: Osteopetrosis (OP) is a rare hereditary disease that causes reduced bone resorption and increased bone density as a result of osteoclastic function defect. Our aim is to review the difficulties, mid-term follow-up results, and literature encountered during the treatment of OP. METHODS: This is a retrospective and observational study containing data from nine patients with a mean age of 14.1 years (9 to 25; three female, six male) with OP who were treated in our hospital between April 2008 and October 2018 with 20 surgical procedures due to 17 different fractures. Patient data included age, sex, operating time, length of stay, genetic type of the disease, previous surgery, fractures, complications, and comorbidity. RESULTS: The mean follow-up period was 92.5 months (25 to 140). Bony union was observed in all of our patients. Osteomyelitis developed in two patients with femoral shaft fractures, and two patients had peri-implant stress fractures. CONCLUSION: Treatment of fractures in OP patients is difficult, healing is protracted, and the risk of postoperative infection is high. In children and young adults with OP who have open medullary canal and the epiphyses are not closed, fractures can be treated with surgical techniques such as intramedullary titanium elastic nail (TENS) technique or fixation with Kirschner (K)-wire.

Medium-term results after treatment of percutaneous tennis elbow release under local anaesthesia.

BACKGROUND: The purpose of this study was to evaluate  the results of the technique of percutaneous release of common extensor procedure under local anesthesia for lateral epicondylitis and to emphasize its simplicity. METHODS: Forty seven elbows (41 patients) were treated surgically for lateral epicondylitis in the outpatient minor procedure room under local anaesthesia. The indication for surgery was continuation of sypmtoms (such as pain, movement and power loss) despite conservative treatment lasting more than six months The treatment results were assessed using the visual analogue scale (VAS) and Mayo Elbow Performance Score (MEPS). RESULTS: Twentysix  right elbows and fifteen left elbows were treated surgically. Dominate elbow rate was 74%. The follow-up period was 36 to 72 months (mean 52 months). All patients had full range of motion. The average post operative pain score was 2.6(range 0 to 9).The average post operative MEPS score was 82 (range 40 to 100). ). Sixteen patients had excellent, twenty  patients had good, two patients had fair and three patients had poor outcomes (repetitive problems). CONCLUSION: The percutaneous release of the common extensor origin is an important treatment option with minimal morbidity, safety, simplicity and good to excellent results in most patients. The procedure can be performed under local anaesthetic and leave a rarely visible scar.

Comparative results of radius distal AO type C1 fractures of elderly women by two different techniques.

ackgrounds: We evaluated clinical and radiographic outcomes of volar locking plates and close reduction with percutaneous pinning treatment approaches for elderly female patients with AO type C1 simple intra-articular distal radius fractures. PATIENTS AND METHODS: We conducted retrospective studies of 72 elderly female patients with AO type C1 simple intra-articular DRFs treated with VLPs or CRPP, from 2012 to 2018. The patients were divided into two groups: There were 38 patients in VLP group and 34 patients in CRPP group. Periodic clinical and radiological evaluation was performed at 2nd, 4th, 6th, 8th weeks and in 6 and 12 months intervals for all patients. We recorded the patient-rated wrist evaluation scores, flexion, extension, supination and pronation degrees and radiographic outcome scores at the end of 6th and 12 months after surgery. RESULTS: A total number of 72 patients were studied. 38 patients were treated with VLP and 34 patients were treated with CRPP .The mean age of the patients was 70,5 years. Comparing the PRWE scores, the VAS scores and the ROM degrees between the 2 groups yielded no significant difference at any time point between 6 months and 1 year. There were no differences in radiographic outcomes at the latest reported follow up between the two interventions and there was no significant difference in the complication between the 2 groups (VLP 6 and CRPP 6) complications. CONCLUSIONS: Complicated surgeries should be avoided because of specific problems in women aged 60 years or older. Our study show that VLP and CRPP techniques had little differences and similar clinical and radiographic results.

The surgery outcomes of pediatric femoral shaft fractures and comparision of radiation risks.

INTRODUCTION: To show midterm results and compare the two methods utilized in pediatric femoral diaphysis fractures fixation and the risks of radiation. METHODS: We conducted retrospective studies of 60 children and adolescent between the age of 6 to 16 years who were exposed to traumatic femoral shaft fractures and treated with methods of fixation titanyum elastic nail (EN), submuscular bridge plating (SBP) Twenty eight (18 males and 10 females) were treated with SBP (group 1), and 32 patients (18 males and 14 females) were treated with EN (group 2). RESULTS: The mean age of the patients was 10,3 years. Duration of follow-up was 29.8 months. Mean union time was 7,4 weeks (range, 6-10 weeks). Operative time was on average 60.6 minutes. Considering Flynn's criteria, the results of treatment was excellent in 50, good in 4 and poor in 6 cases. CONCLUSIONS: In the surgical treatment of pediatric femoral shaft fractures, fixation techniques such as submuscular bridge platingand elastic nails were found to have similar fracture healing and complication rates. An orthopaedic surgeon must protect himself, his personnel and the patient from radiation exposure. Open reduction internal plate fixation can be chosen as an alternative treatment for children who do not cause radiation exposure to the femoral fracture.

What should be the timing of surgical treatment of humeral shaft fractures?

This study aims to evaluate the timing of surgery in surgically treated humeral shaft fractures, to investigate the effects of surgical time on fracture recovery and complications.This was a retrospective and observational study, based on patient data who underwent surgical treatment of humeral shaft fractures from January 2012 to January 2019. There were 52 patients (19 were women and 33 men) with traumatic humeral shaft fractures who were treated consecutively at our hospital.There was a statistically significant difference in time to start physical therapy, time between surgery and bone union, and time between bone fracture and bone union. The mean time to start physical therapy in group 1 was 6.5 weeks (range, 5-12 weeks), it was 10 weeks (range, 6-14 weeks) in group 2 (P < .001). The mean time between surgery and bone union in group 1 was 14.58 weeks (range, 12-20 weeks), it was 17.4 weeks (range, 8-30 weeks) in group 2 (P: .009). The mean time between bone fracture and bone union in group 1 was 113.2 days (range, 86-114 days), it was 179.2 days (range, 89-355 days) in group 2 (P < .001).Classically the first treatment option for humerus shaft fractures is conservative if there is no absolute surgical indication. Surgical treatment may be the first option if patients want to return to early everyday life. Delayed surgery means delayed physical therapy and this means delayed recovery and return to everyday life. In today's technology world, it should be discussed that the initial treatment of uncomplicated humerus shaft fractures is a conservative treatment.

Is there a relationship between forefoot alignment and ingrown toenail? A case-control study.

Biomechanical imbalance between the hallux and the second toe and external compression of the lateral nail fold are proposed as the main reasons for ingrown toenail. Therefore, any anatomical predisposition facilitating this compression may play a role in the occurrence of ingrown toenail. The purpose of this study is to investigate the relationship between forefoot alignment and ingrown toenail. The authors retrospectively reviewed radiographs of 81 patients with ingrown toenails and compared them with 100 healthy subjects regarding forefoot alignment. Hallux valgus angle (HVA), intermetatarsal angle (IMA), and interphalangeal angle (IPA) were measured, and feet were classified according to digital formula as Egyptian, Greek, and square. The mean HVA was 14.5° ± 5.0° in the case group and 13.2° ± 5.9° in the control group. The mean IMA was 9.1° ± 2.5° in the case group and 8.6° ± 3.1° in the control group. The mean IPA was 11.9° ± 4.1° in the case group and 12.0° ± 5.1° in the control group. There was no statistically significant difference between the groups regarding HVA, IMA, or IPA (P = .123, P = .198, and P = .925, respectively). The distribution of foot types between groups was also similar (P = .967). This study has failed to demonstrate any abnormality in forefoot alignment in patients with symptomatic ingrowing toenails, and it is suggested that treatment should not be based on the correction of the anatomy if no abnormality exists.

Can we make a diagnosis with radiographic examination alone in calcaneal apophysitis (Sever's disease)?

The purpose of this study was to investigate whether the identification of Sever's disease is reliable with radiographs alone. Eighty foot radiographs (50 boys with calcaneal apophysitis and 30 healthy boys) were included in this study. Two consultant orthopaedic surgeons were instructed to make a diagnosis without clinical information on the patients. Radiologic assessments were performed in random order by each observer on two separate occasions, at least 3 weeks later. kappa-statistics were used to establish a relative level of agreement between observers for the two readings and between separate readings by the same observer. Observer A made 22 true (27.5%) diagnoses, whereas observer B made 56 true (70%) diagnoses at the first assessment. Interobserver agreement was rated as slight (kappa-value, 0.190). Observer A made 40 true (50%) diagnoses, whereas observer B made 52 true (65%) diagnoses at the second assessment. Interobserver agreement was rated as slight (kappa-value, 0.039). Intraobserver reproducibility was rated as fair for both observers (kappa-value, 0.369 for observer A and 0.253 for observer B). The results of this study showed that the radiologic identification of calcaneal apophysitis without the absence of clinical information was not reliable. Radiologic findings that were attributed to Sever's disease showed a wide variation between independent observers and between separate readings by the same observer. The diagnosis of calcaneal apophysitis is a clinical decision and radiographic assessment seems to be unnecessary.

Effects of topical alkane vapocoolant spray on pain intensity prior to digital nerve block for ingrown nail surgery.

Needle penetration and local anesthetic infiltration are 2 painful steps that cause considerable stress and anxiety during digital nerve block, which is the most frequently used regional anesthesia for ingrown nail surgery. The purpose of this study was to evaluate the effectiveness of topical alkane vapocoolant spray in decreasing pain during digital nerve block for ingrown nail surgery. The authors conducted a prospective, randomized clinical trial with 62 patients who underwent big toenail surgery. Prior to the digital block, alkane vapocoolant spray was applied to patients who were selected by flipping a coin. A visual analog scale (VAS) was used for assessment of pain during the skin needle penetration and during the infiltration of the anesthetic product. VAS scores during needle penetration were significantly lower in the intervention group. However, VAS scores during infiltration were similar statistically. Alkane vapocoolant spray has no noticeable clinical benefit in decreasing pain intensity during digital nerve block in patients undergoing toenail surgery.
