Diagnosis: Glenohumeral Joint Osteoarthritis
Basis of diagnosis: The diagnosis was made in the Diagnostic Assessment by Dr Thomas Perkins dated 28 May 2025, and is supported by an orthopaedic consultation by the orthopaedic surgeon, dated 30 October 2007.
I am satisfied this is the appropriate diagnosis.
In determining your claim for this condition, I have applied the SOP:
Statement of Principles concerning Osteoarthritis (Balance of Probabilities) (No. 62 of 2017)

- for osteoarthritis of a hip joint only, having femoroacetabular impingement syndrome of the affected joint, before the clinical onset of osteoarthritis in that joint
I have noted your contention as to the cause of this condition. The available evidence indicates, I have noted your contention to the cause of your condition. Your service medical records indicate that you presented to the health facility with deep, aching pain in the right shoulder with morning stiffness, grinding on movement, loss of external rotation and pain with overhead work and lifting on 20 September 2007.
The diagnosis was confirmed by X-ray on 20 September 2007, which showed new glenohumeral joint space narrowing and an inferior osteophyte compared with a preserved joint space on 5 March 2007, and by MRI on 11 October 2007, which showed diffuse cartilage loss of the humeral head and glenoid, marginal osteophytes and subchondral cysts. With the clinical findings of mechanical pain, coarse crepitus and loss of external rotation, these findings meet the Statement of Principles definition of osteoarthritis.
This has then led to further investigations and the diagnosis of your condition of Glenohumeral Joint Osteoarthritis. I have accepted your condition of Glenohumeral Joint Osteoarthritis.
Having considered your service records and the available medical evidence, I am satisfied the SOP is met and that this condition is related to your peacetime service.
I have therefore accepted that this condition is related to your service with effect from 12 September 2007.

I have noted your contention as to the cause of this condition. The available evidence indicates, I have noted your contention to the cause of your condition. Your service medical records indicate that you presented to the health facility with deep, aching pain in the right shoulder with morning stiffness, grinding on movement, loss of external rotation and pain with overhead work and lifting on 20 September 2007.
The diagnosis was confirmed by X-ray on 20 September 2007, which showed new glenohumeral joint space narrowing and an inferior osteophyte compared with a preserved joint space on 5 March 2007, and by MRI on 11 October 2007, which showed diffuse cartilage loss of the humeral head and glenoid, marginal osteophytes and subchondral cysts. With the clinical findings of mechanical pain, coarse crepitus and loss of external rotation, these findings meet the Statement of Principles definition of osteoarthritis.
After the condition arose, it was worsened during your service. The psoriatic arthritis of the right shoulder diagnosed in 2003, with a flare of synovitis in February 2010, preceded the documented worsening on 5 October 2010. The Staphylococcus aureus septic arthritis of the right shoulder of May 2003 preceded the worsening on 5 October 2010. The intra-articular humeral head impaction fracture of November 1999 preceded the worsening on 5 October 2010. The haemarthrosis of November 1999, and a second haemarthrosis aspirated after the fall of 3 August 2004, preceded the worsening. Calcium pyrophosphate deposition disease of the right shoulder, confirmed in 2005 with a further attack in March 2009, preceded the worsening. The trauma of 1999 and 2004, and a fall from a maintenance stand onto the right shoulder on 18 April 2010, fell within the 25 years before the worsening, which run from 5 October 1985 to 5 October 2010. The acute chondral tear of the glenoid of November 1999 fell within the 25 years before the worsening. The acute lateral meniscal tear of the right knee of October 1998 fell within the 25 years before the worsening. The cryogenic frostbite over the right shoulder of February 2003 preceded the worsening. The posterior instability and glenoid retroversion persisted throughout the five years before the worsening, from 5 October 2005 to 5 October 2010, with progressive posterior glenoid erosion on CT in 2009. The post-traumatic subchondral osteonecrosis of the humeral head shown in 2001 preceded the worsening. The grip work of more than 30 hours a week from 1988 to 2003 accumulated more than ten years within a continuous 15-year period before the worsening. The use of rivet guns and air hammers on more days than not from 1988 to 2003, about 15 years, fell within the 25 years before the worsening. The asymmetric gait from the right knee injury persisted from October 1998 to the worsening, about twelve years. The lifting of more than 800 000 kilograms in loads of at least 20 kilograms from 1990 to 2000 preceded the worsening, which occurred within the 25 years following that period. The carrying of loads of at least 20 kilograms for about 3 900 hours from 1990 to 2000 preceded the worsening, which occurred within the 25 years following that period. The climbing of more than 150 rungs and stairs a day from 1990 to 2002 fell within the 25 years before the worsening. Your body mass index remained above 25 from 1994 to the worsening, 31.0 in October 2010, more than ten years. Your waist circumference exceeded 102 centimetres from 1995 to the worsening, more than ten years. Your waist circumference exceeded 88 centimetres throughout the ten years before the worsening. The kneeling and squatting of more than an hour a day from 1988 to 2003 preceded the worsening, which occurred within the 25 years following that period. The internal derangement of the right knee from 1998 preceded the worsening. The chondromalacia patellae of the right knee from 1998 preceded the worsening. The axillary nerve injury with loss of sensation and proprioception of the right shoulder persisted from 1999 to the worsening. Paget's disease of the right proximal humerus, diagnosed in 2003, preceded the worsening. Acromegaly, diagnosed in 2003, preceded the worsening. The instability of the right shoulder from 1999 began eleven years before the worsening. The femoroacetabular impingement syndrome of the right hip diagnosed in 2000 preceded the worsening. From January to July 2010 in the Middle East you had no access to orthopaedic review, imaging, physiotherapy or joint injection for the right shoulder, and continued heavy maintenance work, including after the fall of 18 April 2010, before the worsening documented on 5 October 2010.
This has then led to further investigations and the diagnosis of your condition of Glenohumeral Joint Osteoarthritis (Worsening). I have accepted your condition of Glenohumeral Joint Osteoarthritis (Worsening).
Having considered your service records and the available medical evidence, I am satisfied the SOP is met and that the worsening of this condition is related to your peacetime service.
I have therefore accepted that the worsening of this condition is related to your service with effect from 5 October 2010.
