A szerzők 26, rövid szárú csípőprotézis beültetésével szerzett tapasztalataikról számolnak be. A betegek közül 13 férfit és 9 nőt operáltak. Négy esetben végeztek mindkét oldali protézisbeültetést. Tíz esetben jobb, 16 esetben bal oldali csípőt operáltak. Az átlagos utánkövetési idő 16,5 hónap volt. A Harris Hip Score érték átlaga 56,34-ről 98,92-re, az SF-36 átlaga 89,96-ról 100,69-ra nőtt. Egy esetben volt a közvetlen posztoperatív szakban protézis luxatio, amely konzervatív kezelésre gyógyult. Egy esetben észleltek intraoperatív femur infractiót, amelyet elláttak. Szeptikus szövődmény nem volt. Az utánkövetés során aszeptikus protézislazulást nem észleltek. Több esetben dysplasiás betegeket operáltak, ezért ezek ellátása fokozott figyelmet igényelt.

Than: Short term results of total hip prostheses with metaphyseal stem anchorage at our clinicThe authors report about their experience with 26 short stem hip prostheses. They treated 13 men and 9 women with this implant. Bilateral prosthesis implantation was performed in 4 cases. They operated 10 left and 16 right hips. The follow-up period was 16.5 months on the average. The average Harris Hip Score increased from 56.34 to 98.92 and the average SF-36 from 89.96 to 100.69. There was one prosthesis dislocation in the immediate postoperative period which was treated in a conservative manner. Intra-operative femur crack occurred in one case which was treated surgically at the same time. There was neither septic complication, nor aseptic loosening during the follow-up period. Patients with dysplastic hips were operated on in several cases, which required special attention.

“…Finally, PC stems particular architecture and load distribution onto the proximal femur may put them at risk of intraoperative periprosthetic fracture (IPPF). 7 After treating 142 cases with the CFP stem (Waldemar Link GmbH, Hamburg, Germany), Li et al 8 have reported a 7% rate of IPPF of the lateral femoral cortex located at the tip of the stem.…”

Objectives: Compare the clinical and radiological outcome of CFP stem with the MiniHip design in a prospective series, with special interest in intraoperative periprosthetic fracture (IPPF). Methods: We prospectively followed 101 cases treated with the MiniHip stem (Group 1) and 89 with the CFP stem (Group 2) operated between 2010 and 2014. No significant demographic differences were observed between both groups. Median follow-up was 72 months. Average stem length was 41% shorter in the MiniHip group ( p < 0.001). Radiological parameters were measured and a logistcic regression model was created to evaluate factors associated with IPPF. Results: Mean mHHS improved from 54 to 95 in the MiniHip group ( p < 0.001) and from 64 to 98 in the CFP group ( p < 0.001). No significant differences were observed in terms of loosening, infection or instability. We observed 7 IPPFs (3.68%), 3 in group 1 and 4 in group 2. After adjusting for confounders, CFP was not associated with a greater risk of IPPF (OR 3.23; 95% CI, 0.250–42.034, p = 0.368), however, a more complex fracture pattern was observed with this stem design. Prior acetabular fractures were associated with IPPF (OR 66.85; 95% CI, 1.142–3911, p = 0.043). Compared to Dorr A femurs, type Dorr B appeared protective against IPPF (OR 0.039; 95% CI, 0.001–1.109, p = 0.058). Valgus alignment tended to increase the risk of IPPF (OR 20.59; 95% CI 0.870–487.221, p = 0.061). Conclusions: MiniHip showed similar radiological outcomes to CFP at short- to mid-term follow-up without increasing IPPFs with a shorter stem length. Given that CFP produced a more complex IPPF pattern, surgeons should be cautious with alignment of this particular design, especially in Dorr A femur.
