Shockwave treatment in our unit is provided in conjunction with our Urological colleagues. Shock Wave Therapy has been used as a last option in patients with difficult and chronic Orthopaedic conditions with an informed consent for all patients.

Material and Methods: 28 patients from Ealing Hospital and West Middlesex Hospital were referred to The Lithotripsy unit at Charing Cross Hospital for Shock wave therapy.

Patients were consented by the Orthopaedic surgeon and the treatment was administered by urologist

The cases included:

4 Humeral fractures: 1 Case in HIV +ve 19 years old

Results: There was complete resolution of symptoms in the 4 cases of soft tissues.

– Clinical and radiological union in 3 of the 4 Humeral Fracture including HIV+ve and in 2 of 3 tibial fracture and 1 of 2 scaphoid.

Discussion: Shock wave therapy is a new consevative treatment modality used in orthopaedic as the last option before surgery but there is a need for RCT.

The purpose of this study is to report the 1 to 5 year results of arthroscopic Rotator Cuff repairs.

Between November 2001 to May 2003, 115 consecutive patients were operated (73 males and 42 females) with arthroscopic repair. 13 patients were lost to follow up, leaving 102 patients available for follow up. Patients were evaluated using the Constant score, satisfaction levels and ultrasound scan to evaluate cuff integrity. Failures were defined as dissatisfied patients and those who had had a re-operation. Re-tear rate was recorded.

The mean follow up time was 23.8 months (range 12–61). Mean age was 57.3 years (range 23–78). 47% had a history of trauma. There were 107 patients (95.5%) with full thickness tears and 5 (4.5%) had partial thickness tears. Of the full thickness tears, 8 (7.6%) were massive in size, 36 (34%) large, 44 (41.5%) medium and 18(17%) small. Isolated Supraspinatus (SSP) tear was recorded in 83.5% and subscapularis tear in 7 %. A combination of SSP tear with infraspinatus and teres minor was found in 9.6%.

86% had Acromioplasty (ASD) with or without an AC joint excision arthroplasty. Two patients had Bankart repairs in addition at the time of cuff repair.

The mean pre op Constant score was 40.9 points (95% CI 37.3 to 44.5), which had improved to 84.8 (CI 82.2 to 86.9) at last follow-up. 78% returned to same work and 82% returned to pre injury leisure activity. There were 20 re-tears (19.6%). eight of the 102 patients were not satisfied. Five of these patients had revision operation.

Arthroscopic cuff repair shows high satisfaction rate (92%) and good functional results with 20% re-tear rate, while offering all the advantages of arthroscopic surgery.

Arthroscopic Rotator cuff repair is gaining popularity in recent years; however, the results of arthroscopic repairs are yet to be reported. Between November 2001 to May 2003, 115 consecutive patients were operated (73 males and 42 females) with arthroscopic repair. 13 patients were lost to follow up, leaving 102 patients available for follow up.

The mean follow up time was 23.8 months (range 12–61). There were 107 patients (95.5%) with full thickness tears and 5 (4.5%) had partial thickness tears. Of the full thickness tears, 8 (7.6%) were massive in size, 36 (34%) large, 44 (41.5%) medium and 18(17%) small.

Mean age was 57.3 years (range 23–78). 47% had a history of trauma.

Mainly Supraspinatus (SSP) tear was recorded in 83.5% and isolated subscapularis tear in 7%. A combination of SSP tear with infraspinatus and teres minor minor (posterior tear) was found in 9.6%.

86% had Acromioplasty (ASD) with or without an AC joint excision arthroplasty. Two patients had Bankart repairs in addition at the time of cuff repair.

Patients were evaluated using the Constant score, satisfaction levels and ultrasound scan to evaluate cuff integrity. Failures were defined as dissatisfied patients and those who had had a re-operation. Re-tear rate was recorded.

The mean pre op Constant score was 40.9 points (95% CI 37.3 to 44.5), which had improved to 84.8 (CI 82.2 to 86.9) at last follow-up. 78% returned to same work and 82% returned to pre injury leisure activity. There were 20 ultrasound demonstrated re-tears (19.6%). However, the majority of patients with radiological re-tears had good function, pain relief and were satisfied. Eight of the 102 patients were not satisfied. Five of these patients had revision operation.

Arthroscopic cuff repair shows high satisfaction rate (92%) and good functional results while offering all the advantages of arthroscopic surgery.

Introduction: Laser Doppler Flowmetry (LDF) is an established technique for the measurement of perfusion in tissues, which has been applied in animal and human studies. Despite many studies the implications of perfusion and blood flow abnormalities in the rotator cuff (RC) in vivo are not clearly understood. This study aims to assess the blood flow in the normal and diseased RC using Laser Doppler Flowmetry (LDF) technique.

Methods: With Ethics approval and informed consent patients undergoing arthroscopy for impingement or cuff tear (diseased cuff) or for shoulder instability (normal cuff) were recruited. Following diagnostic arthroscopy and bursoscopy measurements of the blood flux in the RC using the LDF were made at 6 points. Five of these were in the cuff over a 4 cm² area from the insertion at the greater tuberosity (A,E – @ Tuberosity level, C-Muscelotendinous junction, B,D – between the two) and one (F) in the deep surface. Diseased RC were subgrouped into mild (B1), moderate (B2) and severe (B3- cuff tear) impingement grades (Copeland-Levy Classification). The arthroscopy, grading, and probe placement were made by the two senior authors. LDF flux (unit of measurement of the perfusion – LDFf) was recorded over 30 seconds at each measurement point. The mean of these readings was calculated.

Results: 56 patients were recruited. 35 Males (62.5%) and 21 Females (37.5%).

336 measurements were recorded.

The observed mean LDFf was 32.8 (27.4–38.1; 95% CI) , 25.4 (22.4–28.5) and 43.1 (37.8–48.4; 95% CI) For Normal, Impingement and Tear cases, respectively (p< 0.0001, One-way ANOVA).

The LDFf was lowest in the Impingement without tear grade (B2) with a statistically significant increase at the edges of a cuff tear.

Conclusion: Preliminary recordings of LDF show changes are in keeping with current knowledge of the pathology. LDFf decreases with advancing impingement, being least affected in the musculotendinous junction. There is a substantial increase in LDFf at the edges of RC tears. This might reflect an attempted reparative response.

Aim: Despite many studies the implications of perfusion and blood flow abnormalities in the rotator cuff (RC) in vivo are not clearly understood. Laser Doppler Flowmetry (LDF) is an established technique for the measurement of perfusion in tissue, which has been applied in animal and human studies. This study aims to evaluate Laser Doppler Flowmetry (LDF) as a technique for the assessment of blood flow in the normal and diseased RC.

Methods: With Ethics committee approval and informed consent patients undergoing arthroscopy for impingement or cuff tear (diseased cuff) and instability (normal cuff – BO) were recruited. Following diagnostic arthroscopy and bursoscopy measurements of the LDF in the RC tear were made at 6 points. Five of these were in the cuff over a 4 cm. 2 are from the insertion at the greater tuberosity and one in the deep surface.

Diseased RC were sub grouped into mild (B1), moderate (B2) and severe (*B3 – cuff tear) impingement grades (Copeland – Levy Classification). The arthroscopy, grading, and probe placement were made by the senior authors. LDF flux (LDFf) was recorded over 30 seconds at each measurement point. The mean of these readings was then calculated (LDF flux – an arbitrary unit of measurement of the perfusion).

Results: 35 patients were recruited. 210 measurements were recorded, in 6 anatomical locations. The mean LDFf was 34.1 in diseased RC and 55.3 in normal RC (p=0.0002). The mean LDFf was 52.2 in severe (RC tear) impingement and 30.3 in mild and moderate impingement’s (p< 0.0001).

The LDFf was lowest in the moderate grade with a significant increase at the edges of a cuff tear.

Conclusion: Preliminary recording of LDFf show changes are in keeping with current knowledge of the pathology. LDFf decreases with advancing impingement. There is an increase in LDFf at the edges of RC tears. This might reflect a reparative response.
