@thearmclinic
Disclaimer
• Study supported by OrthoSpace
@thearmclinic
Size does Matter!
• Tear Size is strongest predictor of failure:

• Independent of:

• Age

• Tissue Quality

• Time to Surgery
• Cho & Rhee. Clin Orth Surg. 2009
• Le, Lam, Murrell. AJSM. 2014
@thearmclinic
@thearmclinic
History
• InSpace Originally intended and marketed as an
alternative to repair of Massive Cuff Tears

• Why?

• High failure rates of repair

• Long recovery period

• Costly

• Complications • Brislin, Field, Savoie. Arthroscopy. 2007
@thearmclinic
InSpace Balloon
• Biodegradable PLLA copolymer

• Three sizes

• Filled with saline

• Starts to degrade at 2-3 months

• Fully disintegrated by 12 months
• Bozkurt M, Akkaya M, Gursoy S et al. Arthrosc Tech. 2005
• Holschen M, Brand F, Agneskirchner JD.Obere Extremität. 2016
• Reduces subacromial friction

• Extends the subacromial space

• Keeps humeral head centred
during dynamic movement
@thearmclinic
History
• First case series intended as a safety & efficacy study - Massive
Irreparable Cuff Tears

• Very low complication rate

• Good Results 

• = humeroplasty, biceps tenotomy, etc.

• = Partial cuff repair series

• But not as good as results of Reverse Arthroplasty
• Jost, Pfirrmann, Gerber. JBJS. 2000
• Green A. JAAOS. 2003
• Dines DM, Moynihan DP, Dines JS, McCann P. JBJS. 2006
• Neri BR, Chan KW, Kwon YK. JSES. 2009
• Bedi A, Dines J, Warren RF, Dines DM. JBJS. 2010
@thearmclinic
So for MRCT:
InSpace Balloon:
• Quicker
• Easier
• Cheaper
• Safer
• Faster Recovery
Repair / Recon:
• Expensive
• Complex
• Long recovery
• Complications
• High failure
VALUE
@thearmclinic
RCT: InSpace vs Repair for MRCT
• Randomized, Two Arm, Subject Blind

• Inclusion: >40yr, MRCT (>5cm)

• Exclusion: Major Trauma, Arthritis, Irreparable, Revision

• Outcomes: ASES, DASH, Constant, EQ-5D-5L,

• 6wks, 3m, 6m, 1yr (MRI), 2yrs

• Primary Efficacy: 10 point change

• Interim Analysis 20 subjects with 6m follow-up
ClinicalTrials.gov: NCT02208440; REC ref: 13/NW/0754; Protocol: IS-CL-02-UK; IRAS: 122315
@thearmclinic
RCT: InSpace vs Repair for MRCT
• RESULTS (Jan 2017):

• 24 subjects:

• 14 with 6m data = 9 Balloon & 5 Repair

• 1 Balloon patient withdrawn to RTS after 6m

• Results so far: NO DIFFERENCE at any stage
ClinicalTrials.gov: NCT02208440; REC ref: 13/NW/0754; Protocol: IS-CL-02-UK; IRAS: 122315

  • 4. @thearmclinic Size does Matter! • Tear Size is strongest predictor of failure: • Independent of: • Age • Tissue Quality • Time to Surgery • Cho & Rhee. Clin Orth Surg. 2009 • Le, Lam, Murrell. AJSM. 2014
  • 6. @thearmclinic History • InSpace Originally intended and marketed as an alternative to repair of Massive Cuff Tears • Why? • High failure rates of repair • Long recovery period • Costly • Complications • Brislin, Field, Savoie. Arthroscopy. 2007
  • 7. @thearmclinic InSpace Balloon • Biodegradable PLLA copolymer • Three sizes • Filled with saline • Starts to degrade at 2-3 months • Fully disintegrated by 12 months • Bozkurt M, Akkaya M, Gursoy S et al. Arthrosc Tech. 2005 • Holschen M, Brand F, Agneskirchner JD.Obere Extremität. 2016 • Reduces subacromial friction • Extends the subacromial space • Keeps humeral head centred during dynamic movement
  • 8. @thearmclinic History • First case series intended as a safety & efficacy study - Massive Irreparable Cuff Tears • Very low complication rate • Good Results • = humeroplasty, biceps tenotomy, etc. • = Partial cuff repair series • But not as good as results of Reverse Arthroplasty • Jost, Pfirrmann, Gerber. JBJS. 2000 • Green A. JAAOS. 2003 • Dines DM, Moynihan DP, Dines JS, McCann P. JBJS. 2006 • Neri BR, Chan KW, Kwon YK. JSES. 2009 • Bedi A, Dines J, Warren RF, Dines DM. JBJS. 2010
  • 9. @thearmclinic So for MRCT: InSpace Balloon: • Quicker • Easier • Cheaper • Safer • Faster Recovery Repair / Recon: • Expensive • Complex • Long recovery • Complications • High failure VALUE
  • 10. @thearmclinic RCT: InSpace vs Repair for MRCT • Randomized, Two Arm, Subject Blind • Inclusion: >40yr, MRCT (>5cm) • Exclusion: Major Trauma, Arthritis, Irreparable, Revision • Outcomes: ASES, DASH, Constant, EQ-5D-5L, • 6wks, 3m, 6m, 1yr (MRI), 2yrs • Primary Efficacy: 10 point change • Interim Analysis 20 subjects with 6m follow-up ClinicalTrials.gov: NCT02208440; REC ref: 13/NW/0754; Protocol: IS-CL-02-UK; IRAS: 122315
  • 11. @thearmclinic RCT: InSpace vs Repair for MRCT • RESULTS (Jan 2017): • 24 subjects: • 14 with 6m data = 9 Balloon & 5 Repair • 1 Balloon patient withdrawn to RTS after 6m • Results so far: NO DIFFERENCE at any stage ClinicalTrials.gov: NCT02208440; REC ref: 13/NW/0754; Protocol: IS-CL-02-UK; IRAS: 122315
