The Delto-pectoral approach is the workhorse of the shoulder surgeon, but surprisingly the common variants of the cephalic vein and deltoid artery have not been documented. The vascular anatomy encountered during one hundred primary elective delto-pectoral approaches was documented and common variants described.

Two common variants are described. A type I (71%), whereby the deltoid artery crosses the interval and inserts directly in to the deltoid musculature. In this variant the surgeon is unlikely to encounter any vessels crossing the interval apart from the deltoid artery itself. In a type II pattern (21%) the deltoid artery runs parallel to the cephalic vein on the deltoid surface and is highly likely to give off medial branches (95%) that cross the interval, as well as medial tributaries to the cephalic vein (38%).

Knowledge of the two common variants will aid the surgeon when dissecting the delto-pectoral approach and highlights that these vessels crossing the interval are likely to be arterial, rather than venous. This study allows the surgeon to recognize these variations and reproduce bloodless, safe and efficient surgery.

Eighty-eight consecutive patients with symptomatic rotator cuff tears were entered in to a prospect study with a novel technique of open double row repair using a ‘Capstan’ screw technique. The medial row has standard anchors, but the lateral suture row is a 35mm × 6.5mm ‘Capstan' screw. This allows up to 28 suture bridges to be taken from the medial row to the lateral row compressing the footprint and spreading the load. This creates a very robust repair or ‘bulletproof repair’. This was used for medium to large isolated supraspinatus tears

Each patient had a pre and post operative Oxford Shoulder Score (OSS), American Shoulder and Elbow Score (ASES Score). The mean pre-operative OSS was 22 (maximum 48) and the mean post-operative OSS was 45, (p < 0.0001). Flexion improved from a mean of 117° to 172° (p < 0.0001). The clinical re-tear rate was 3.4%. 95% were satisfied with the procedure. There were no deep infections. 18% had transient stiffness, 6% stiffness at one year but none severe enough to warrant release. There were no instances of deltoid dysfunction.

This demonstrates excellent results in terms of OSS, patient satisfaction and function. Clinical re-tear rate is markedly reduced in comparison to previous literature.

Massive tears of the supraspinatus of the rotator cuff lead to painful loss of movement. The literature supports repair of these tears for young healthy individuals, however they present a surgical challenge with historically poor results from both athroscopic and standard open techniques.

Prof Bunker has developed a surgical technique for massive rotator cuff tears with a Grammont Osteotomy of the spine of the acromion, when standard surgical techniques will not allow the necessary exposure: the so called “Full Monty”.

Patients were entered in to a prospective study to obtain the functional benefit of this procedure. Each patient had a pre-operative American Shoulder Elbow Score (ASES) Oxford Shoulder score (OSS), pain score, range of movement. Post-operatively these measures were repeated along with a patient questionnaire on function and satisfaction.

The mean American Shoulder score (ASS) preoperatively was 7 (out of a possible 30) and improved postoperatively to 23(P = 0.00011). The improvement in the Oxford Shoulder Score was 22 (out of a possible 48) preoperatively to 43 postoperatively (0.0001) and 80% patients stated their treatment was “successful”.

We believe this a successful surgical option for a patient with “massive” rotator cuff tear that is not amenable to standard surgical techniques.

Given that there is limited time available to the surgeon in arthroscopic rotator cuff repair, how is the time best spent? Should they place one Modified Mason-Allen, two mattress or four simple sutures? This study reverses current thought. In an in-vitro biomechanical single pull to failure study we compared the ultimate tensile strength of simple, mattress and grasping sutures passed with an arthroscopic suture passer (Surgical Solutions Express-Sew). The aim was to determine which suture configurations would most simply, repeatably and reliably repair the rotator cuff.

The ultimate tensile strength and mode of failure of six different suture configurations was repeatedly tested on a validated porcine rotator cuff tendon model, using a standard suture material (Number 2 Fiberwire) passed with the Surgical Solutions Express-sew, in a Hounsfield type H20K-W digital tensometer.

Standardising the number of suture passes to four, the strongest construct was two mattress sutures (Mean 169N), followed by single Modified Kessler (Mean 161N), four simple sutures (Mean 155N) and finally a single Mason Allen suture (Mean 140N). Suture configurations involving two passes were all weaker than those with four (one way analysis of variance p=0.026), even when Number 2 Fibertape was used to augment strength.

These results show little difference in strength for varying complexity of four pass suture passage (one way analysis of variance p=0.61). In simple terms there is no demonstrable difference in the strength of construct whether the surgeon uses four simple, two mattress or one grasping suture. This study allows the surgeon to justify using the simplest configuration of suture passage that works in his hands in order to obtain a reliable and repeatable repair of the rotator cuff arthroscopically.

Ultrasound imaging has become an essential adjunct to clinical examination when assessing a patient with suspected rotator cuff pathology. With the new high-resolution portable machines it has become feasible for the shoulder surgeon to perform the scans himself in the clinic and save a great deal of time. This study was conducted to examine the accuracy of the ultrasound scans performed by a single surgeon over a period of four years (2001-2004).

The ultrasound findings were uniformly documented and collected prospectively. Out of a total of 364 scanned patients we selected 143 who ultimately received an operation and we compared the surgical findings with the ultrasound reports. The intra-operative findings included 77 full thickness supraspinatus tears, 24 partial thickness tears and 42 normal cuffs. Three full thickness tears were missed on ultrasound and reported as normal/ partially torn. Four normal/ partially torn cuffs were thought to have a full thickness tear. This presents 96.3% sensitivity and 94.3% specificity for full thickness tears. Three partial thickness tears were reported normal on ultrasound and eight normal cuffs were thought to have partial thickness tears. This presents 89% sensitivity and 93.7% specificity for partial thickness tears. The size estimation of full thickness tears was more accurate for large/massive tears (96%) than moderate (82%) and small/pinhole tears (75%). The tear sizes were more often underestimated which may partly reflect disease progression during the unavoidable time lag between scan and surgery.

We conclude that shoulder ultrasound performed by a sufficiently trained orthopaedic surgeon is a safe and reliable practice to identify rotator cuff tears.
