“…To the best of our knowledge, few cases of bilateral TOH have been described to date. Some previous case reports focus on simultaneous bilateral TOH without complications (3,6) or leading to a fracture of the femoral neck during pregnancy (7). Two distinctive characteristics of the present case are worth addressing.…”

SummaryWe describe a case of non-simultaneous bilateral hip pain with bone marrow edema occurring in an adult male, with the contralateral hip being involved 12 years later after the onset of symptoms. On the basis of clinical and imaging findings, together with a complete resolution after conservative management, a post-hoc diagnosis of metachronous bilateral transient osteoporosis of the hip (TOH) was made. Non-simultaneous bilateral presentation of TOH is exceptional, and contralateral involvement with a 12-year delay has never been previously described.

“…

Dear Editor, We read with great interest the recent article by Dr. Xyda et al [1] reporting the magnetic resonance (MR) findings in three cases of postpartum bilateral transient osteoporosis of the hip (TOH) [1]. This article provides new evidence that the onset of TOH related to pregnancy may occur not only in the third trimester, as described in most articles, but also early after delivery [2].

“…Gentile Editore, abbiamo letto con grande interesse l'articolo recentemente pubblicato sul vostro giornale dal Dr. Xyda et al che descrive tre casi di osteoporosi transitoria bilaterale dell'anca nel periodo post-parto [1]. Tale articolo ha il merito di confermare che l'esordio dell'osteoporosi transitoria dell'anca può osservarsi non solo durante il terzo trimestre di gravidanza, come riportato classicamente in letteratura, ma anche durante il periodo post-parto [2].…”

“…L'insieme di queste osservazioni potrebbe corroborare l'ipotesi che il coinvolgimento simultaneo di entrambe le anche si osserva in alcuni casi di osteoporosi transitoria dell'anca correlata alla gravidanza, mentre nella popolazione maschile, nelle forme bilaterali, si osserverebbe piuttosto un pattern di tipo migrante con interessamento successivo delle due anche. Lequesne [3] I sincerely thank Dr. Simoni and colleagues for their interest in our paper regarding postpartum bilateral transient osteoporosis of the hip (TOH) [1]. Bilateral involvement in TOH is rare [2].…”

“…However, I do not agree with Simoni et al's hypothesis that bilateral involvement might occur in pregnancy-related TOH, but not in men, who would more likely develop the migratory pattern of TOH. The limited number of cases on bilateral involvement available in the literature and the retrospective Vorrei ringraziare sinceramente il Dr. Simoni e i colleghi per l'interesse che hanno mostrato nei confronti del nostro lavoro riguardante l'osteoporosi bilaterale transitoria postpartum dell'anca (TOH) [1].…”

Dear Editor, We read with great interest the recent article by Dr. Xyda et al. [1] reporting the magnetic resonance (MR) findings in three cases of postpartum bilateral transient osteoporosis of the hip (TOH) [1]. This article provides new evidence that the onset of TOH related to pregnancy may occur not only in the third trimester, as described in most articles, but also early after delivery [2]. To date, postpartum TOH had been reported only anecdotally due to the lack of large series [2]. Most previous reports of pregnancy-related bilateral TOH do not specify pain onset was synchronous for both hips or whether there was a side-to-side migration over a period of months.The report of Xyda et al. of three cases of bilateral synchronous TOH in postpartum parallels the observations of , who recently reported five patients with synchronous and bilateral pregnancy-related TOH. These observations might corroborate the hypothesis that the simultaneous involvement of both hips might occur in some cases of pregnancy-related TOH, but not in men, who would be more prone to develop a side-to-side migratory TOH. Lequesne [3], in his classic description of TOH in a population of ten men, found three cases of bilateral "migrating" involvement over a period of months, but none of them had a synchronous involvement.When it comes to the images shown in Xyda et al.'s article, we beg to add some comments. First, in the second and third case presented, the images in T1-weighted sequences would seem to show a subtle subchondral hypointense band paralleling the articular surface. In TOH, the detection of such subtle linear images may correspond to a epiphyseal fracture, and differentiation from an epiphyseal osteonecrosis may be challenging in some cases [4]. In Gentile Editore, abbiamo letto con grande interesse l'articolo recentemente pubblicato sul vostro giornale dal Dr. Xyda et al. che descrive tre casi di osteoporosi transitoria bilaterale dell'anca nel periodo post-parto [1]. Tale articolo ha il merito di confermare che l'esordio dell'osteoporosi transitoria dell'anca può osservarsi non solo durante il terzo trimestre di gravidanza, come riportato classicamente in letteratura, ma anche durante il periodo post-parto [2]. L'insorgenza di un'osteoporosi transitoria dell'anca era stata documentata in letteratura solo a titolo aneddotico, a causa della mancanza di serie sufficientemente numerose di pazienti [2]. Inoltre, la maggior parte dei precedenti casi riportati di osteoporosi bilaterale dell'anca, non specificano se l'insorgenza della sintomatologia era sincrona per le due anche o se si trattava, piuttosto, di un quadro di dolore e di impotenza funzionale con migrazione all'anca controlaterale realizzatosi nell'arco di alcuni mesi. La descrizione di Xyda et al. di tre casi di osteoporosi transitoria bilaterale dell'anca nel post-parto si aggiunge alle osservazioni di , che hanno recentemente decritto 5 pazienti gravide con un'osteoporosi transitoria bilaterale dell'anca ad esordio sincrono. L'insieme di queste osservazioni pot...
