Rapidly Destructive Coxopathy With Femoral Head Fracture That Is Similar to a Slipped Capital Femoral Epiphysis in an Elderly Woman: A Case Report

Slipped capital femoral epiphysis (SCFE) generally occurs in adolescents but rarely in adults. Rapidly destructive coxopathy (RDC) is characterized by rapid joint destruction, including disruption of the joint at the femoral head and acetabulum as well as reduction of the joint space, within six to 12 months. The mechanism of RDC is likely multifactorial but has not yet been identified. Moreover, there are no reports of displaced femoral head fractures similar to an SCFE associated with RDC. We report a rare case of RDC with femoral head fracture that is similar to SCFE in an 86-year-old woman. Although the exact cause of the femoral head fracture is unknown, it can develop into RDC. Awareness of orthopedic surgeons regarding this condition is crucial for appropriate treatment, by monitoring the presentation of symptoms and imaging/radiographic findings.

Slipped Capital Femoral Epiphysis Associated with Endocrinopathy: A Narrative Review

»

Slipped capital femoral epiphysis (SCFE) has a well-documented association with underlying endocrine conditions, including thyroid hormone aberrations and parathyroid dysfunction.

»

Recombinant growth hormone therapy has also been identified as a risk factor for the development of SCFE.

»

Presentation before their 10th birthday or after their 16th birthday along with height of <10th percentile are reliable risk factors for identifying children with an SCFE who are at a heightened risk for an underlying endocrinopathy and can been used to guide selective laboratory testing.

»

Patients with unilateral SCFE presentations with an underlying endocrinopathy are at a heightened risk for contralateral slip development and should be treated with prophylactic fixation.

Slipped capital femoral epiphysis with hypopituitarism in adults: A case report and literature review

RATIONALE

Slipped capital femoral epiphysis (SCFE) is a common disease in pediatric orthopedics. Most research on SCFE has focused on high-risk groups or the whole population, and studies focusing on adult SCFE patients are rare. In the present study, we report the case of an adult patient with SCFE.

PATIENT CONCERN

A 37-year-old man presented to our clinic with persistent pain that was poorly localized to both hips, groin regions, and thighs for more than 1 year.

DIAGNOSES

A bilateral hip X-ray examination was performed, and the femoral epiphyses were found to be unfused on both sides. Low levels of growth hormone (GH), insulin-like growth factor-1 (IGF-1), triiodothyronine (T3), thyroxine (T4), follicle-stimulating hormone, luteinizing hormone, estradiol, and testosterone, and high levels of thyroid-stimulating hormone, prolactin, and cortisol.

INTERVENTIONS

Hormone-substitution therapies (levothyroxine sodium to treat hypothyroidism and testosterone enanthate to treat hypogonadism) were prescribed. Total hip arthroplasty was performed to treat femoral epiphysis slippage.

OUTCOMES

After 6 months of postoperative follow-up, the patient's gait improved significantly, and bilateral hip pain was relieved.

LESSONS

When treating adults with SCFE, clinicians must be alert to endocrine disorders. Comprehensive imaging evaluation is crucial for the accurate diagnosis and selection of an appropriate treatment.

Slipped Capital Femoral Epiphysis in an Adult with Panhypopituitarism: A Case Report

CASE

Our patient was a 31-year-old woman with previously undiagnosed panhypopituitarism who presented with bilateral slipped capital femoral epiphysis (SCFE). Together with endocrinology, her treatment plan involved medical management of her panhypopituitarism and surgical correction with femoral neck osteotomy. Hormone deficiencies were corrected 6 weeks after replacement therapy began, and the patient was cleared for surgery. By 5 months after osteotomy, examination revealed delayed union and prominent screws bilaterally. Hardware exchange and repeat internal fixation were then performed. At 8 weeks after revision, she presented with avascular necrosis, and the decision was made to proceed with total hip arthroplasty. A 5-year follow-up period was documented.

CONCLUSION

This case presented a rare look at SCFE in an adult patient with panhypopituitarism. Other systemic illnesses that can contribute to SCFE or other orthopaedic issues include, but are not limited to, multiple endocrine neoplasia syndromes, vitamin D deficiency, renal osteodystrophy, Kallmann syndrome, Klinefelter syndrome, and pathologies affecting the thyroid and pituitary gland.

Slipped Capital Femoral Epiphysis in an Adult Patient With Kabuki Syndrome

Introduction:

Slipped capital femoral epiphysis (SCFE) is a condition which predominantly occurs in adolescents. SCFE is extremely rare in adults, and nearly all previous reported cases have been associated with an endocrine disorder.

Methods:

We present a case of a 19-year-old man with Kabuki syndrome who was diagnosed with an unstable SCFE requiring surgical fixation. A literature search on PubMed and Google Scholar was done looking for all published cases of delayed-onset SCFE. All previous reported cases were reviewed to determine the likely cause of the SCFE.

Results:

No previous cases of SCFE were described in patients with Kabuki syndrome. Literature review revealed 27 articles describing 32 cases of delayed-onset SCFE. Thirty-one of these cases were associated with endocrine disorders or pituitary tumors. Endocrine disorders associated with delayed-onset SCFE included hypothyroidism, hypogonadism, and panhypopituitarism. Pituitary adenomas and craniopharyngiomas were also associated with delayed-onset SCFE.

Discussion:

This is the first reported case of SCFE in a patient with Kabuki syndrome. Kabuki syndrome is a genetic disorder known to cause delayed growth, resulting in delayed physeal closure, placing the patients at risk of SCFE even into adulthood. The literature search revealed that nearly all previously described delayed-onset SCFE cases were associated with endocrine disorders or pituitary tumors. We recommend that all patients diagnosed with delayed-onset SCFE be evaluated for endocrine disorders, pituitary tumors, and/or genetic disorders which can cause delayed skeletal maturation as these disorders can range from severe endocrine disorders to intracranial tumors.

A new compound heterozygous mutation in a female with 17α-hydroxylase/17,20-lyase deficiency, slipped capital femoral epiphysis, and adrenal myelolipoma

17α-Hydroxylase/17,20-lyase deficiency (17-OHD) is a rare disease caused by mutations of the CYP17A1 gene. Slipped capital femoral epiphysis (SCFE) rarely occurs in adults. There are occasional reports of adrenal myelolipoma (AML) in 17-OHD. A 27-year-old Chinese female (46, XX) visited the hospital for SCFE and presented with continuous hypokalemia, absent spontaneous puberty, and hypertension. Hypergonadotropic hypogonadism was detected. The laboratory tests were consistent with 17-OHD. AML was considered based on the imaging examinations. A mutation analysis of the CYP17A1 gene identified the following compound heterozygous mutation: a frame-shift mutation, i.e. c.985_987delTACinsAA (p.Tyr329fs), that had been reported to be a common mutation in the Chinese population was found in exon 6. Another new nonsense mutation, i.e. c.1270C > T (p.Gln424*), that causes a premature termination codon was found in exon 8. Treatment with prednisone had poor efficacy. The administration of 0.75 mg dexamethasone and estradiol/dydrogesterone cyclic treatment significantly improved the patient's symptoms. For the first time, we report a 17-OHD case accompanied by SCFE, AML, and a novel mutation site in the CYP17A1 gene. We provide insight into the clinical manifestations, genetic analysis, and treatment options of 17-OHD.
