“…The scans were made for morphological evaluation of the acetabular and proximal femur before total hip arthroplasty [19]. The overall average age of the patients was 47 years (range 35–61 years), the mean weight was 55 kg (range 50–69 kg), and the mean height was 157 cm (range 155–170 cm).…”

“…With the technique of multiplanar reconstruction (MPR), the frontal pelvic plane was established using both anterior superior iliac spines and the pubic tubercles and subsequent axes from this [19,25], we selected the frontal plane through greater trochanter, The length of the gluteus medius from its origin to its insertion was measured as a straight line [10] (shown in Figure 3). …”

BackgroundThe gluteus medius muscle is essential for gait and hip stability. Changes that occur in the gluteus medius muscles in patients with developmental dysplasia of the hip (DDH) are not well understood. A better understanding of DDH related changes will have positive repercussions toward hip soft tissue reconstruction.Methods19 adult patients with unilateral DDH scheduled for total hip arthroplasty were assessed for: cross-sectional area (CSA), radiological density (RD) and the length of gluteus medius using computed tomograhpy(CT) (scanned before THA). Hip abductor moment arm and gluteus medius activation angle were also measured via hip anteroposterior radiographs.ResultsBoth CSA and RD of gluteus medius muscle were significantly reduced (p < 0.05) in the affected hip compared to the control. In the affected hip, the length of the gluteus medius muscle was reduced by 8-11 % (p < 0.05) while the gluteus medius activation angle was significantly increased (p < 0.05) and the hip abductor moment arm was decreased (p < 0.05).ConclusionsThe gluteus medius showed substantial loss of CSA, RD as well as decreased length in patients with DDH in the affected hip. These changes should be considered in both hip reconstruction and postoperative rehabilitation training in patients with DDH.

“…CT Scans for this particular question are not routinely performed and are usually not requested by the surgeon planning THR surgery. Thickness of the medial acetabular wall based on CT scans varies with different measurement techniques and locations [8,13,17] and therefore comparison of values remains controversial. Stein et al first published different acetabular distances using computer tomography with different anatomical questions with regard to prosthetic hip surgery.…”

Objective Knowledge of acetabular anatomy is crucial for cup positioning in total hip replacement. Medial wall thickness of the acetabulum is known to correlate with the degree of developmental dysplasia of the hip (DDH). No data exist about the relationship of routinely used radiographic parameters such as Wiberg's lateral center edge angle (LCE-angle) or Lequesne's acetabular index (AI) with thickness of the medial acetabular wall in the general population. The aim of our study was to clarify the relationship between LCE, AI, and thickness of the medial acetabular wall. Materials and methods Measurements on plain radiographs (LCE and AI) and axial CT scans (quadrilateral plate acetabular distance QPAD) of 1,201 individuals (2,402 hips) were obtained using a PACS imaging program and statistical analyses were performed. Results The mean thickness of the medial acetabulum bone stock (QPAD) was 1.08 mm (95% CI: 1.05-1.10) with a range of 0.1 to 8.8 mm. For pathological values of either the LCE (<20°) or the AI (>12°) the medial acetabular wall showed to be thicker than in radiological normal hips. The overall correlation between coxometric indices and medial acetabular was weak for LCE (r =−0.21. 95% CI [−0.25, -0.17]) and moderate for AI (r = 0.37, [0.33, 0.41]). Conclusions We did not find a linear relationship between Wiberg's lateral center edge angle, Lequesne's acetabular index and medial acetabular bone stock in radiological normal hips but medial acetabular wall thickness increases with dysplastic indices.

“…i sar. su izneli veoma interesantan zaključak svog istraživanja po kojem je dubina medijalnog zida acetabuluma značajno manja kod pacijenata sa manjim stepenom acetabularne displazije 109 . Ovaj podatak je od velike koristi za preoperativno planiranje totalne aloartroplastike kuka kod pacijenata sa nedovoljno razvijenim acetabulumom.…”

EFIKASNOST UGRADNJE TOTALNE BESCEMENTNE ENDOPROTEZE KUKA NAKON OSTEOTOMIJE ILIJAČNE KOSTI METODOM PO CHIARI-JU SAŽETAK UVODNepotpuna natkrovljenost glave butne kosti se karakteriše poremećenim anatomskim odnosima u zglobu kuka i predstavlja stanje između pozicija apsolutne podudarnosti i potpunog odsustva kontakta dveju zglobnih površina. U mlađoj životnoj dobi najčešće je asimptomatska i predstavlja uzgredan radiografski nalaz. Osteotomija ilijačne kosti po Chiari-ju predstavlja jednu od takozvanih osteotomija "spasavanja" koje imaju za cilj smanjivanje tegoba, pre svega bola, kod pacijenata sa nepopravljivo narušenim oblikom zglobnih površina. Bila je veoma rasprostranjena i često korišćena metoda u lečenju razvojnog poremećaja kuka i drugih ortopedskih stanja praćenih nepotpunom natkrovljenošću glave butne kosti. Kod velikog broja takvih pacijenata vremenom su se razvile degenerativne promene koje zahtevaju nove hirurške intervencije, pre svega zamenu zgloba veštačkim. Aloartroplastične hirurške procedure su kod pacijenata sa značajno izmenjenim anatomskim odnosima u zglobu kuka izuzetno složene i nepredvidljive, a broj intraoperativnih komplikacija i kasnijih reintervencija nije zanemarljiv. CILJEVI• Utvrditi i uporediti funkcionalni status nakon ugradnje totalne bescementne endoproteze kuka u grupi pacijenta kod kojih je prethodno učinjena osteotomija ilijačne kosti metodom po Chiari-ju u odnosu na grupu pacijenata kod kojih takva procedura nije učinjena, iako je postojala indikacija;• Dokazati opravdanost osteotomije ilijačne kosti metodom po Chiari-ju u smislu očuvanja funkcije zgloba kuka i odlaganja daljih hirurških procedura, pre svega ugradnje veštačkog zgloba;• Ustanoviti tehničke poteškoće prilikom ugradnje i definisati najčešće komplikacije nakon ugradnje totalne bescementne endoproteze kuka kod pacijenata prethodno operisanih metodom po Chiari-ju;• Uporediti radiografske parametre totalne endoproteze kuka između dve grupe ispitivanih pacijenata radi procene trajnosti implantata. MATERIJAL I METODOLOGIJAIstraživanjem je obuhvaćeno ukupno 75 pacijenata, odnosno 93 kuka, lečenih u Institutu za Ortopedsko-hirurške bolesti "Banjica" u Beogradu zbog tegoba koje su posledica nepotpune natkrovljenosti glave butne kosti. Ugradnja totalne bescementne endoproteze kuka je izvršena u periodu između 1990. i 2009. godine. Na osnovu dostupne medicinske dokumentacije formirane su dve grupe ispitanika:• GRUPA I -pacijenti prethodno lečeni Chiari-jevom osteotomijom ilijačne kosti kao jedinom operativnom procedurom (39 pacijenata, 46 kukova);• GRUPA II (KONTROLNA) -prethodno neoperisani pacijenti kod kojih je postojala indikacija za Chiari-jevu osteotomiju ilijačne kosti (36 pacijenata, 47 kukova).Analizirani su parametri natkrovljenosti glave butne kosti na radiografijama karlice sa kukovima u anteroposteriornom smeru pre i nakon osteotomije ilijačne kosti REZULTATIProsečna starost pacijenata u vreme osteotomije ilijačne kosti po Chiari-ju iznosila je 37,1±9,4 godina. Ova operacija je najčešće izvođena kod pacijena...
