BACKGROUND: Discectomies are a common surgical treatment for disc herniations in the canine spine. However, the effect of these procedures on intervertebral disc tissue is not fully understood. The objective of this study was to assess degenerative changes of cervical spinal segments undergoing discectomy procedures, in vivo. RESULTS: Discectomies led to a 60% drop in disc height and 24% drop in foraminal height. Segments did not fuse but showed osteophyte formation as well as endplate sclerosis...

Bryant Ho, Judith Baumhauer
An estimated 40% of the US population have foot problems.Of all patients aged over 50 years, 2.5% report degenerative arthritis of the first metatarsophalangeal (MTP) joint, termed 'hallux rigidus'. First MTP osteoarthritis is the most common arthritic condition in the foot.Progression of great toe arthritis is associated with pain and loss of motion. Non-surgical intervention begins with shoe modifications and orthotics designed to limit MTP motion.In patients with mild arthritis, operative procedures focus on removing excess osteophytes (cheilectomy) to prevent dorsal impingement with or without a concomitant osteotomy (Moberg) to improve or shift range of motion into a less painful arc...

Late stage ankle osteoarthritis often presents with debilitating pain. It is common to find osteophytes and loose body formation around the joint. Total ankle arthroplasty can preserve joint mobility and pain relieve for such patient. However, when trying to remove the osteophytes and loose bodies at the posterior ankle joint, there is risk of damaging posterior structures such as the neurovascular bundle during the procedure. We are presenting a case where the posterior loose bodies remained untouched during the operation, and patient showed spontaneous resolution of the lesions with time...

Hallux rigidus is a degenerative disease of the first metatarsalphalangeal (MTP) joint and affects 2.5% of people over age 50. Dorsal osteophytes and narrowed joint space leads to debilitating pain and limited range of motion. Altered gait mechanics often ensued as 119% of the body force transmit through the 1(st) MTP joint during gait cycle. Precise etiology remains under debate with trauma being often cited in the literature. Hallux valgus interphalangeus, female gender, inflammatory and metabolic conditions have all been identified as associative factors...

The anatomical shape of bones and joints is important for their proper function but quantifying this, and detecting pathological variations, is difficult to do. Numerical descriptions would also enable correlations between joint shapes to be explored. Statistical shape modelling (SSM) is a method of image analysis employing pattern recognition statistics to describe and quantify such shapes from images; it uses principal components analysis to generate modes of variation describing each image in terms of a set of numerical scores after removing global size variation...
