“…The pre-operative templating is performed on 2D analog or digital X-rays in most orthopaedic centers. The low predictability of this approach for templating has been shown in previous publications [47][48][49]. This is more applicable to The ICC is defined as the ratio between explained variances (variance attributable to the cause of variation: observer factor; repetition of measurement) and overall variance (explained variance + error variance).…”

“…La planificación preoperatoria se realizó de acuerdo con métodos analógicos convencionales. 26,27 Según la técnica quirúrgica, se programó, con exactitud, el corte del cuello femoral para evitar la elongación excesiva de la pierna operada y calcular la lateralización de la cadera. En casos con lateralización aumentada, se realizó un corte de cuello más vertical y, en casos de lateralización disminuida, un corte de cuello más horizontal, como bien fue descrito por Teoh y cols 3 .…”

Objetivo: Determinar los resultados clínicos, la supervivencia y la incidencia de fractura periprotésica intraoperatoria con un tallo corto tipo 2B de fijación cervicometafisaria.Métodos: Se analizaron prospectivamente los primeros 100 tallos (84 pacientes) MiniHipTM (Corin, Cirencester, Reino Unido) colocados, en forma consecutiva, por un mismo cirujano. La edad promedio fue de 47 años. La indicación para un tallo corto fue: edad <55 años (85 casos) o la participación previa en deportes de impacto en pacientes de entre 56 y 60 años (15 casos). El diagnóstico inicial fue artrosis primaria de cadera en el 82% de los casos. El seguimiento promedio fue de 42 meses. Resultados: El puntaje en la escala de Harris modificada mejoró de 55 a 96 al final del seguimiento (p = 0,02) y ningún paciente refirió dolor de muslo en el posoperatorio. La supervivencia del tallo fue del 99% (IC95% 93,1-99,8). Un caso presentó una perforación de la cortical lateral intraoperatoria, tratado con revisión con un tallo no cementado convencional. Un paciente tuvo una infección aguda, que fue tratada con desbridamiento, retención de componentes y antibióticos, con resultado favorable a los 48 meses de la cirugía. Se produjeron 3 fracturas incompletas del calcar intraoperatorias (3%).Conclusiones: Se obtuvieron resultados excelentes en esta serie de pacientes jóvenes y activos operados por un mismo cirujano con un tallo corto tipo 2B, a los 2-5 años de seguimiento, con un 1% de falla por falsa vía femoral intraoperatoria. AbstractObjectives: We sought to determine our 2 to 5-year survivorship, intraoperative fractures, subsidence and thigh pain rate in a consecutive, independent, one surgeon series of patients in whom a type-2B short stem was implanted.Patients and Methods: The first 100 type 2B consecutive short femoral stems implanted in 84 patients with a mean age of 47 years old were reviewed. Indications included age younger than 55 years (85 hips), or participation in impact sports in patients aging 56 to 60 years old (15 hips). Initial diagnosis was osteoarthritis in 82% of the cases. Median follow-up was 42 months.Results: Stem survival rate was 99% at 2 to 5 years for stem revision for any aseptic reason and 98% when infection was included. The mean Harris Hip Score improved significantly from 55 to 96 at final follow-up (p 0.02). There was one lateral cortex perforation, and three intraoperative calcar incomplete fractures (3%), only one of them required cerclage wiring and delayed weightbearing. No patient referred thigh pain at final follow-up. Only one case subsided 4 mm and then stabilized. The risk of revision was 1% at 2 to-5 years (95%CI 93.1-99.8%).Conclusions: Promising short-term results with this design were observed in this single surgeon, non-designerconsecutive series including the learning curve period using a type 2B short stem in young active patients, in which bone preservation is justified.

“…Most of the preoperative techniques are based on overlay templating and determining accurate position and size of implants. 8,16,[31][32][33][34][35][36] The use of templates is the first step in obtaining acceptable clinical results with regard to limb length. However, such use should be combined with a reliable intraoperative method to obtain optimal length.…”

Limb length discrepancy after total hip arthroplasty: a systematic review

et al. 2018

<p class="abstract">Correcting limb length inequality without compromising hip stability is one of the major intraoperative challenges in Total hip arthroplasty (THA) as it is a major cause of patient dissatisfaction and litigation against surgeon. Surgeons performing THA should aim to minimize Limb Length Discrepancy (LLD), and therefore should adopt a reliable method of doing so. Thus a reproducible technique which effectively reduces postoperative LLD without increasing operative time and is easy to apply is a need of time. Although various preoperative and intraoperative techniques are described in literature, none is universally applicable and is without limitations. We are presenting a review of 50 articles on limb length discrepancy after total hip arthroplasty, its implications and several techniques to avoid it. We suggest that every effort should be made to minimise postoperative Limb Length Discrepancy by combined use of preoperative and intraoperative techniques.</p>
