the aims of surgical treatment for cholesteatoma include complete removal of disease and formation of a dry, self cleaning ear in addition to hearing reconstruction. this presentation concentrates on techniques of open mastoid surgery or modified radical mastoidectomy to achieve a well-constructed cavity. this study analyzes both primary and revision mastoid surgery referred to the author. all ...

BACKGROUND Between 5 and 20% of patients undergoing ACL reconstruction fail and require revision. Animal studies have demonstrated slower incorporation of allograft tissue, which may affect the mechanism of graft failure. The purpose of this study is to determine the location of traumatic graft failure following ACL reconstruction and investigate differences in failure patterns between autograf...

Reconstruction of the anterior cruciate ligament (ACL) is widely accepted as the treatment of choice for individuals with functional instability due to an ACLdeficient knee. It is estimated that anywhere between 60,000 and 75,000 ACL reconstructions are performed annually in the United States, although this number may be as high as 350,000. Despite the fact that nearly 90% of index ACL reconstr...

We previously reported early favourable results concerning allograft use in proximal humerus reconstruction following malignancy. We now present the long-term follow-up of patients who underwent tumour resection with massive humeral allograft reconstruction. This is a retrospective review of 8 consecutive patients who underwent massive proximal humeral allograft for primary or secondary bone tu...

The current study aimed to evaluate the outcome of a continuous and prospective series of 61 revision THAs with AAOS grade III and IV acetabular bone defect reconstruction using a Kerboull cross-plate, structural allograft and cemented dual mobility cup (Saturne, Amplitude, Valence, France). At a 7.5-year mean follow-up, no instability was reported after revision. In addition, no failure of the...

PURPOSE The purpose of this study was to evaluate the effect of graft size on patient-reported outcomes and revision risk after anterior cruciate ligament (ACL) reconstruction. METHODS A retrospective chart review of prospectively collected cohort data was performed, and 263 of 320 consecutive patients (82.2%) undergoing primary ACL reconstruction with hamstring autograft were evaluated. We r...
