BACKGROUND: Ganz surgical hip dislocation via a posterior (Kocher-Langenbeck) approach is a popular procedure in the management of femoroacetabular impingement (FAI). We report the results of surgery performed through an anterolateral (Watson-Jones) approach in the management of anterolateral FAI. METHODS: Twenty-one hips in 20 patients (mean age at the time of operation, 17.3 years) were treated surgically using an anterolateral approach: 12 hips with Legg-Calvé-Perthes disease, three septic hips, three hips with avascular necrosis (combined with slipped capital femoral epiphysis [SCFE], femoral neck fracture, and developmental dislocation of the hip), two hips with epiphyseal dysplasia, and one hip with SCFE. All patients had anterolateral FAI. Surgical hip dislocation was performed in four hips with trochanteric osteotomy. Combined osteotomies were for neck lengthening in 11 hips, varus or valgus osteotomy in the proximal femur in four hips, and pelvic osteotomy in four hips. Clinical results were evaluated using a modified Harris hip score (mHHS). RESULTS: Range of hip flexion and abduction showed statistically significant improvement after surgery; however, the improvement in mean mHHS was not statistically significant. CONCLUSIONS: An anterolateral approach can be used as an alternative to a posterior approach in the management of anterolateral FAI with or without hip dislocation while safely preserving the blood supply to the femoral head and allowing simultaneous procedures in the proximal femur.

BACKGROUND: Prophylactic pinning of the uninvolved side after unilateral slipped capital femoral epiphysis (SCFE) is controversial. The alpha angle, a measurement of femoral head-neck aspherity, was proposed as a predictor of progression of contralateral SCFE with a treatment threshold of greater than 50.5°. The aim of this study was to evaluate its validity in our cohort of patients. METHODS: A retrospective review of a 10-year series of patients who presented with unilateral SCFE was conducted. Minimum follow-up duration to identify contralateral progression was 18 months. Age, sex, ethnicity, and endocrinopathies were noted. Alpha angle measurements of the unaffected hip were performed by two independent observers. The average values of measurements were used for analysis. Univariate and multivariate logistic regression analyses were performed to identify predictors of contralateral progression. A receiver operating characteristic (ROC) curve was generated. RESULTS: There were 43 patients with unilateral SCFE. Seven patients (16.3%) developed contralateral SCFE. There were 31 males (72.1%) and 12 females (27.9%). The mean duration from index surgery to contralateral fixation was 43.9 weeks (range, 16.2 to 77 weeks). The mean alpha angle was significantly higher in the patients with contralateral progression (mean, 50.7°; standard deviation [SD], 5.4°; range, 43.8° to 58.5°) than in the patients without progression (mean, 43.0°; SD, 4.2°; range, 33.0° to 52.5°; p < 0.001). The alpha angle was also identified as a statistically significant predictor of contralateral progression on multivariate analysis (p = 0.02). The intraclass correlation coefficient for interobserver reliability was moderately strong at 0.76 (95% confidence interval, 0.55 to 0.87). The area under the ROC curve was 0.88. The treatment threshold of 50.5° had a sensitivity of 0.43, specificity of 0.94, and number needed to treat (NNT) of 2.7. The ideal treatment threshold derived from the ROC curve was 49.0°, which had a sensitivity of 0.71, specificity of 0.89, and an NNT of 1.7. CONCLUSIONS: Alpha angle is a potential predictor of contralateral hip involvement in children with SCFE who may benefit from prophylactic hip fixation. Results from our series suggest a treatment threshold be 49.0°. However, given the limited sample size and moderately strong interobserver reliability, larger studies are needed to validate our findings.

OBJECTIVETo evaluate the results of surgical treatment for moderate or severe slipped capital femoral epiphysis (SCFE) using modified Dunn procedure through the approach of surgical hip dislocation at the interval of minimum 12 months follow-up.

METHODSFrom November 2011 to June 2013, 6 patients (7 hips) with SCFE were treated in department of pediatric orthopedics, Hospital Affiliated to Shanghai Jiaotong University School of Medicine, they all had trauma history. The patients were aged from 10-15 years, mean 13.6 years. The duration of symptoms ranged from 4 to 35 days, average 14.2 days. The degree of slip was averagely 45% (25%-55%). In 6 patients (except right side of 1 case was treated in situ with cannulated screws) were surgically treated using modified Dunn procedure through the approach of surgical hip dislocation. Postoperatively the brace was used for immobilizing the hip for 4 weeks, then 4 weeks of bed traction combined with rehabilitation program of hip joint activity. Eight weeks later, the gradual touchdown weight bearing was being allowed.

RESULTSThe follow-up time ranged from 12 to 30 months, average 23.8 months. Six patients have been able to walk without crutches, no obvious limp. X-ray film showed femoral epiphysis line on the bit of good recovery, no appearance of avascular necrosis of the femoral head, joint space was normal. The Harris score of hip evaluation was 94.7 averagely, ranging 85-100, at the time of last follow-up.

CONCLUSIONSApplication of surgical treatment for moderate or severe SCFE with open reduction through the approach of surgical hip dislocation is a valid alternative method. The femoral head epiphysis can be capable of restoring anatomy, at present no case occurred avascular necrosis, and patients are satisfied with the function of the hip joint.

Craniopharyngiomas are rare primary intracranial tumors. Despite their benign histological appearance, they are often associated with an unfavorable prognosis. The typical manifestations upon diagnosis are headache, visual impairment, polyuria/polydypsia, growth retardation, disturbance of pubertal development, and significant weight gain. The treatment options include radical surgery or radiotherapy, or a combination of these modalities. Slipped capital femoral epiphysis (SCFE) is the most common adolescent hip disorder. SCFE occurs when the capital femoral epiphysis displaces posteriorly on the femoral neck at the level of the physis. The etiology of SCFE is thought to be multifactorial and may include obesity, growth surges, and less common endocrine disorders. The related endocrine disorders include hypothyroidism, growth hormone supplementation, hypogonadism, and panhypopituitarism. Reported herein is a case of panhypopituitarism caused by craniopharyngioma combined with SCFE.

PURPOSE: Long-acting gonadotropin-releasing hormone agonists (GnRHa) are commonly used to treat central precocious puberty (CPP) in Korea. Although rare, there have been reports on the characteristic of adverse reactions of GnRHa in CPP among the Korean population. This study was intended to report on our clinical experience regarding significant adverse reactions to long-acting GnRHa in CPP and early onset puberty and to evaluate the prevalence rate of serious side effects. METHODS: This retrospective study included children with CPP and early onset puberty, who were administered monthly with long-acting GnRHa (leuprolide acetate, triptorelin acetate) at the outpatient clinic of Department of Pediatrics, at Inha University Hospital, between January 2011 and December 2013. We analyzed the clinical characteristics of patients who experienced significant adverse reactions and evaluated the prevalence rate. RESULTS: Six serious side effects (0.9%) were observed among total of 621 CPP and early onset puberty children with GnRHa therapy. The number of sterile abscess formation was four in three patients (4 events of 621). Anaphylaxis occurred in only one patient, and unilateral slipped capital femoral epiphysis (SCFE) in another one patient. Anaphylaxis occurred after the 6th administration of the monthly depot triptorelin acetate. Unilateral SCFE developed in GnRHa therapy. CONCLUSION: Sterile abscess formation occurred in 0.6% of CPP and early onset puberty patients from the administration of a monthly depot GnRHa therapy. The occurrences of anaphylaxis and SCFE are extremely rare, but can have serious implications on patients. Clinicians should be aware of these potential adverse effects related to GnRHa therapy in CPP.

Growth hormone (GH) has been available for more than 4 decades for the treatment of GH deficiency. But mass production of recombinant DNA growth hormone has made GH therapy widely available for children with no GH deficiency. The use of GH therapy in children has resulted in adverse effects ranging from minor disturbances such as edema and injection site reactions to more significant, but rare events such as benign intracranial hypertension and slipped capital femoral epiphysis. Yet there has been no report in the dermatological field on skin adverse effects associated with GH therapy. We report here on 2 cases of psoriasis following GH therapy in children.

Slipped capital femoral epiphysis is a rare hip disorder that mainly occurs in pubertal children. Although the exact cause of this disorder is unknown, it is known to be associated with obesity, trauma, delayed sexual development, delayed bone maturation, chronic renal failure, genetic diseases, endocrine disorders (growth hormone deficiency, hypothyroidism, hypogonadism), growth hormone therapy, and gonadotropin releasing hormone agonist (GnRH agonist) therapy. We report 2 cases of slipped capital femoral epiphysis in adolescent females who were receiving growth hormone therapy. The first case is of a 16 year-old-girl with chronic renal failure and renal osteodystrophy. The second case is of an 11 year-old-girl with idiopathic precocious puberty who had received GnRH agonist and growth hormone therapy. Unilateral or bilateral slipped capital femoral epiphysis developed at 1 year 3 months after treatment in both the cases. The chief complaints were pain in the hip joint and lower extremities. Growth hormone and/or GnRH agonist therapy was stopped, and in situ screw fixations of the involved hip epiphyses were performed.

Slippage of the upper femoral epiphysis can occur in association with endocrine disorder. A 14-year-old male patient, who complained of pain on multiple joints including both hips, was diagnosed with bilateral slipped femoral epiphysis due to primary hyperparathyroidism. At a single operation, the epiphyses were pinned-in situ, and the tumor was removed. After parathyroidectomy, the calcium and the parathyroid hormone levels promptly resolved. The pinning-in situ of both femoral heads was done for the purpose of preventing further displacement of the femoral epiphyses, and we aimed for epiphysiodesis. The permanent biopsy of the tumor was parathyroid adenoma. The physes of both femoral heads were closed and the widened physes of both distal tibias resolved postoperatively.

Though femoral neck fractures in adults are usually treated by fixation with multiple screws, subtrochanteric fracture at the insertion site is an uncommon complication, and in children, there has been a few reports about this complication after treatment of slipped capital femoral epiphysis. We report a subtrochanteric fracture at the insertion site of cannulated screws used in femoral neck fracture of a 9-years old boy.

PURPOSE: To evaluate physeal remodeling after internal fixation of slipped capital femoral epiphysis, We performed a retrospective review of the medical records and radiographs of 14 children (17 cases) who had had slipped capital femoral epiphysis. MATERIALS AND METHODS: We reviewed 14 patients who had slipped capital femoral epiphysis. They were divided two groups. Group I were in situ pinning with single screw and group II were corrective osteotomy with multiple pinning. We identified physeal remodeling camparing with their preoperative, postoperative and last follow-up radiographs with measuring physeal- shaft angle. RESULTS: Early closure of the physis was observed in 6 cases among 14 patients (17 hips). Compared with their postoperative radiographs, the last follow up radiographic study revealed that physeal remodeling was observed in 4 patients (4 hips) at group I (mean, 7.8degree), in 2 patients (3 hips) at group II (mean, 10.7degree). CONCLUSION: In this study, physeal remodeling was observed in 4 patients (4 hips) in group I and 2 patients (3 hips) in group II. The incidence of physeal remodeling was related with degree of epiphyseal slippage, and age was not related with physeal remodeling potential.
