Inclusion Criteria

• The subject has signed an Institutional Review Board (IRB)-approved, study specific Informed Consent Form (ICF).
• The subject is skeletally mature
• The subject has a diagnosis as listed in the instructions for use (IFU), which include non inflammatory degenerative joint disease (including osteoarthritis or avascular necrosis), rheumatoid arthritis or post-traumatic arthritis, correction of functional deformity, treatment of nonunion, femoral neck and trochanteric fractures.

Exclusion Criteria

• The subject is pregnant or breastfeeding

Primary Outcome Measures

Name	Time	Method
Survival Rate	10 years	Evaluation of the survival rate for Insignia Hip Stem is defined as absence of femoral stem revision for aseptic loosening or device-related femoral fracture.
Harris Hip Score (HHS)	10 Years	The Harris Hip Score (HHS) assesses pain, function, joint deformity and range of motion.; Scores can range from 0 to 100 with 0 being the worst and 100 being the best score.; A score of 80-100 is considered good-excellent and a score of less than or equal to 79 is considered fair-poor. 90-100 = excellent 80-89 = good 70-79 = fair 0-69 = poor

Secondary Outcome Measures

Name	Time	Method
Harris Hip Score (HHS)	pre-op, 6 week, 1,2,5 and 7 years	The Harris Hip Score (HHS) assesses pain, function, joint deformity and range of motion.; Scores can range from 0 to 100 with 0 being the worst and 100 being the best score.; A score of 80-100 is considered good-excellent and a score of less than or equal to 79 is considered fair-poor. 90-100 = excellent 80-89 = good 70-79 = fair 0-69 = poor
EQ-5D - Visual analogue scale (VAS)	pre-op, 6 week, 1,2,3, 4,5,7 and 10 years	The EuroQol-5 Dimension (EQ-5D) is a subject-completed questionnaire designed to assess subject health state values.; With the EQ Visual Analogue Scale (VAS) the respondents can report their perceived health status with a grade ranging from 0 (the worst possible health status) to 100 (the best possible health status).
Survival Rate	2 years	Evaluation of the survival rate for Insignia™ Hip Stem is defined as absence of femoral stem revision for aseptic loosening or device-related femoral fracture; Success rate at two (2) years postoperative with the Insignia™ Hip Stem is not worse than 98 % with a non-inferiority margin of 3.5%.; Success rate at 10 years postoperative with the Insignia™ Hip Stem is not worse than 95% with a non-inferiority margin of 5%.
EQ-5D - Descriptive System	pre-op, 6 week, 1,2,3, 4,5,7 and 10 years	The EuroQol-5 Dimension (EQ-5D) is a subject-completed questionnaire designed to assess subject health state values.; The EQ-5D descriptive system comprises the following five dimensions: mobility self care, usual activities, pain/comfort and anxiety/depression. Each dimension has 3 levels indicating no problems, some problems or extreme problems. The index values on a scale between -1 (low) and 1 (high) are showing the average health status according to the 5 dimensions: A low score shows worse health and a high score shows better health.
