Each probe provides fractional data (abdominal probe for pleural-alveolar characterization, cardiac probe for posterior analysis in challenging patients, vascular probe if others cannot show lung-sliding, abdominal again for assessment of artifacts length, etc).. Most microconvex probes found in laptop machines do not have the resolution or range of ours.
The management of retinal detachment in a high myopic eye, with posterior staphyloma, poses a challenge for the retinal surgeon.
Although there were many different types of fixation techniques for sacroiliac dislocation fracture, the treat remained challenging in posterior pelvic ring injury.
Translating current knowledge and treatment guidelines to children requiring posterior fossa surgery is challenging.
However, obtaining any data from the literature, comparing these parameters between the anterior and posterior circulation IAs, is challenging.
Another anatomic challenge in the posterior maxilla is the pneumatization of the maxillary sinus which can limit the length of implant that can be placed.
The clinical diagnosis of a superior labral anterior posterior (SLAP) tear is extremely challenging.
Lap-LAR of the rectum in cases of middle and low rectal cancer, without the posterior approach, can be technically challenging.
Due to its restricted size and the critical structures it contains, the posterior cranial fossa (PCF) is challenging for the neurosurgeon and each procedure exposes the patient to early and dramatic post-operative supratentorial (acute hydrocephalus) and/or infratentorial (brain swelling and/or hemorrhage) complications.
Soft-tissue reconstruction of large posterior heel ulcerations represents a formidable challenge because of the specialized nature of the tissues; relatively immobile surrounding tissues; proximity to underlying tendon, bone, and neurovascular tissues; and limited soft-tissue flap procedures available.
