Limb-length discrepancy after total hip arthroplasty (THA) leads to patient dissatisfaction and can be a cause of orthopedic surgery malpractice cases. Nonsurgical and surgical techniques exist to correct limb-length discrepancies. Two limb-lengthening methods were used to correct greater than 2-cm limb-length discrepancies after THA: lengthening over a femoral nail with an external fixator and...

Internal lengthening nail (ILN) is a recent development in limb lengthening and deformity correction specialty. The ILN has the distinct advantage of combining acute deformity correction with gradual lengthening of bone. While using ILN, the short metaphyseal bone fragment may develop a deformity at the time of osteotomy and nail insertion or during bone lengthening because of the wide medullar...

Despite numerous advantages, knee disarticulations (KDs) are rarely performed because of the anticipated KD prosthesis fitting problems that include the positioning of the knee joint distally from the KD socket. This results in lengthening of the thigh and subsequent shortening of the shank. The objective of this study was to assess the cosmetic effect of the knee joint in a KD prosthesis by de...

In view of the possibility that the mechanism of mitral regurgitation following premature ventricular contractions may contribute to the understanding of mitral regurgitation in clinically important causes of nonrheumatic mitral insufficiency, we studied 320 premature ventricular contractions in eight dogs. Since the papillary muscle is an important component of the mitral valvular complex, the...

This study focuses on the acoustic-phonetic cues at discourse and syntactic boundaries in English, Guoyu, Putonghua, and Japanese. Speech was elicited by having talkers describe the events in The Pear Story film. Recorded data were transcribed and segmented into discourse and syntactic units. Acousticphonetic measurements of syllable duration and syllable onset intervals (SOIs) were taken on th...

BACKGROUND phonological disorders. AIM to verify the occurrence of vocalic lengthening, through acoustic analysis, in a group of 16 children (8 boys and 8 girls) with evolutive phonological disorders (EPD), who did not present in their speech /R/ and /S/ medial codas; to verify the occurrence percentage of lengthening and omission strategies in the two types of coda. METHOD recordings of 16...

Many phonetic and phonological processes resemble one another, which has led some researchers to suggest that phonetics and phonology are essentially the same. This study compares phonetic and phonological processes of consonant lengthening by analyzing duration measurements collected from Hungarian speakers (n = 14). Affricates, which crucially possess a two-part structure, were placed in targ...

Muscle contracture and joint stiffness are a major concern during limb lengthening using the Ilizarov method. The aim of this study was to detect factors that may influence the final loss of knee flexion. We retrospectively studied knee movement in 32 patients undergoing femoral lengthening using the Ilizarov method. The pattern of loss of knee movement showed a rapid fall in knee flexion durin...
