A large percentage of the skin tumors that dermatologic surgeons treat are located on the nose. Of these, a significant percentage are located on the nasal tip. The nasal tip is notoriously difficult to reconstruct and we present a bilateral rotation flap that may be useful in some instances for reconstruction of this area.

Background: There exists a need for validated lumbar spine models in spine biomechanics research. Although cadaveric testing is the current gold standard for spinal implant development, it poses significant issues related to reliability and repeatability due to the wide variability in cadaveric physiologies. Moreover, there are increasing ethical concerns with human dissection practices.

Background: Unilateral sacral fractures with posterior ring instability represent a prevalent type of posterior pelvic ring fracture. While lumbo-pelvic fixation is recognized as a highly stable method, the sufficiency of unilateral lumbo-pelvic fixation (ULF) for such fractures remains under debate.
Purpose: This study aims to assess the biomechanical stability of ULF compared to traditional bilateral lumbo-pelvic fixation (BLF) and triangular osteosynthesis (TO), incorporating clinical observations, and previous biomechanical data.

Purpose: The study aimed to compare the short-term outcomes (3.7±0.4yrs) of full-arch immediately loaded fixed maxillary prostheses supported by conventional and unilateral single zygomatic implants versus those supported by conventional and bilateral single zygomatic implants.

A boy with bilateral congenital anomalies of the upper extremities with transverse absence of the left arm (agenesis) and absence of right thumb (disgenesis), fixed elbow in extension due to humeroradial synostosis thought that the humerus was intact. His wrist could move passively with 50° flexion, 0° extension, and 70° radial deviation. The other 4 fingers were intact, 4-5 metatarsal bones were in synostosis, and the fifth finger was clinodactyly.

Purpose: To propose a new sign of patellar maltracking in recurrent patellar dislocation (RPD) and compare the differences in lower limb rotational and bony structural abnormalities among the different signs.
Patients And Methods: A retrospective study included 279 patients (mean age: 22 years; female: 81%) who underwent primary surgery for RPD over the past 4 years was performed. The patients were grouped based on the characteristics of patellar tracking: low-, moderate- and high-grade J-sign.
