Hip disorders and treatments
Research Guide
What is Hip disorders and treatments?
Hip disorders and treatments encompass conditions such as femoroacetabular impingement syndrome, osteoarthritis, and traumatic arthritis of the hip, along with diagnostic methods like radiological assessment and treatments including hip arthroscopy, mold arthroplasty, and total hip replacement.
The field includes 65,981 papers focused on femoroacetabular impingement syndrome, where abnormal hip morphology damages acetabular cartilage and labrum, potentially leading to osteoarthritis. Key areas cover radiographic diagnosis, surgical techniques, outcomes of hip arthroscopy, and hip morphology's influence on joint mechanics. Growth rate over the past 5 years is not available.
Topic Hierarchy
Research Sub-Topics
Femoroacetabular Impingement Radiographic Diagnosis
This sub-topic examines imaging techniques including alpha angle measurement and cross-sectional imaging for diagnosing cam and pincer morphologies in femoroacetabular impingement syndrome. Researchers study diagnostic accuracy, reliability of radiographic parameters, and integration with MRI for early detection.
Hip Arthroscopy Surgical Techniques
This sub-topic covers arthroscopic procedures for labral repair, acetabuloplasty, and femoroplasty in treating femoroacetabular impingement. Researchers investigate portal placements, instrumentation, and technical modifications to optimize surgical outcomes.
Acetabular Labral Tears Treatment
This sub-topic focuses on repair versus debridement strategies for acetabular labral pathology in the context of hip impingement. Researchers analyze biomechanical restoration, healing rates, and long-term joint health following labral interventions.
Hip Morphology Biomechanics
This sub-topic explores computational modeling and in vitro studies of how abnormal morphologies like cam deformities alter hip joint contact mechanics. Researchers quantify impingement zones, cartilage stress, and labral loading under dynamic conditions.
Hip Arthroscopy Clinical Outcomes
This sub-topic evaluates patient-reported outcomes, return to sport rates, and osteoarthritis progression following hip arthroscopy for impingement. Researchers conduct prospective studies on modified Harris Hip Scores and risk factors for revision surgery.
Why It Matters
Hip disorders contribute substantially to musculoskeletal burdens, with indirect costs predominant as noted by Woolf and Pfleger (2003) in "Burden of major musculoskeletal conditions." Osteoporosis-related fractures exceeded 2 million incidents costing nearly $17 billion in 2005 alone, with men accounting for over 25% of the burden, according to Burge et al. (2006) in "Incidence and Economic Burden of Osteoporosis-Related Fractures in the United States, 2005–2025." Ganz et al. (2003) in "Femoroacetabular Impingement" identified abnormal contact between femoral head and acetabulum as a cause of idiopathic osteoarthritis, informing surgical interventions like those for labral tears and cam deformities. Harris (1969) in "Traumatic Arthritis of the Hip after Dislocation and Acetabular Fractures" analyzed 39 mold arthroplasties, providing end-result data on post-traumatic arthritis treatment.
Reading Guide
Where to Start
"Femoroacetabular Impingement" by Ganz et al. (2003), as it provides foundational explanation of abnormal hip morphology causing cartilage damage and osteoarthritis, central to the topic.
Key Papers Explained
Ganz et al. (2003) in "Femoroacetabular Impingement" establishes pathogenesis linking morphology to osteoarthritis, which Glyn-Jones et al. (2015) and Hunter and Bierma-Zeinstra (2019) in their "Osteoarthritis" papers expand on clinically. Kellgren and Lawrence (1957) in "Radiological Assessment of Osteo-Arthrosis" offers diagnostic basis that Harris (1969) in "Traumatic Arthritis of the Hip after Dislocation and Acetabular Fractures" applies to treatment outcomes via mold arthroplasty. Lewinnek et al. (1978) in "Dislocations after total hip-replacement arthroplasties" and Brooker et al. (1973) in "Ectopic Ossification Following Total Hip Replacement" address total hip replacement complications building on arthroplasty themes.

Advanced Directions
Research emphasizes outcomes of hip arthroscopy for femoroacetabular impingement and labral tears, alongside hip dysplasia influences on mechanics. No recent preprints or news available, so frontiers remain in refining arthroscopic techniques against historical benchmarks like mold arthroplasty.

Frequently Asked Questions
What is femoroacetabular impingement?
Femoroacetabular impingement occurs due to abnormal contact between the femoral head and acetabulum from factors like biochemical, genetic, and acquired abnormalities. Ganz et al. (2003) in "Femoroacetabular Impingement" explain it contributes to idiopathic osteoarthritis when the pathomechanism in dysplastic hips is absent. It damages acetabular cartilage and labrum.
How is osteoarthritis of the hip diagnosed radiologically?
Radiological assessment identifies osteo-arthrosis features in the hip. Kellgren and Lawrence (1957) in "Radiological Assessment of Osteo-Arthrosis" established methods for grading such changes. This approach evaluates joint space narrowing and osteophytes.
What treatments address traumatic arthritis after hip dislocation?
Mold arthroplasty treats traumatic arthritis following acetabular fractures or dislocations. Harris (1969) in "Traumatic Arthritis of the Hip after Dislocation and Acetabular Fractures" reported outcomes from 39 procedures at Massachusetts General Hospital between 1945 and 1965. Banaszkiewicz (2013) in "Traumatic Arthritis of the Hip After Dislocation and Acetabular Fractures: Treatment by Mold Arthroplasty: An End-Result Study Using a New Method of Result Evaluation" used new evaluation methods for end-results.
What are complications of total hip replacement?
Dislocations occur in 3% of total hip replacements, linked to acetabular cup anteversion. Lewinnek et al. (1978) in "Dislocations after total hip-replacement arthroplasties" analyzed 300 cases, finding anterior dislocations with increased anteversion. Ectopic ossification affects 21% of patients six months post-surgery, as per Brooker et al. (1973) in "Ectopic Ossification Following Total Hip Replacement."
What is the burden of hip-related fractures?
Osteoporosis-related fractures exceed 2 million annually, costing nearly $17 billion in 2005. Burge et al. (2006) in "Incidence and Economic Burden of Osteoporosis-Related Fractures in the United States, 2005–2025" predict continued rises through 2025. Men represent over 25% of cases.
How does hip morphology influence osteoarthritis?
Abnormal hip morphology in femoroacetabular impingement leads to cartilage and labrum damage, causing osteoarthritis. Ganz et al. (2003) in "Femoroacetabular Impingement" detail cam deformities and their role in joint mechanics. This affects treatment strategies like arthroscopy.
