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.

Introduction

Massive rotator cuff tears in the patient who is too young for a reverse shoulder replacement are a challenging situation. A technique using a ‘Grammont osteotomy’ of the acromion has been developed to allow a comprehensive approach, the so called “Full Monty”.

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.

We present a retrospective analysis of 50 cases of cuff tear arthropathy, treated over past seven year period by use of reverse geometry shoulder prosthesis. 98% follow-up was achieved with average follow up of 3 years. Mean (SD) age was 81.3 (9.2) years and female to male ratio was 5:1. Six patients had bilateral reverse geometry shoulder replacements. Patients were assessed with preoperative Oxford and American Shoulder and Elbow Scores Society score (pre-op ASES) and post-operative American Shoulder and Elbow Society Score (post-op ASES), Oxford, Constant and SF36 scores. Mean pre-op ASES was 22.29 (95%CI: 9.1 – 37.9) and post-op ASES score was 65.2 (95%CI: 48.5 – 81.9), (P< 0.001, Paired t-test). Mean post operative Oxford score was 27.25 (95% CI: 18.4 – 27.6). Mean post operative Constant score was 63.2 (95% CI: 52.6 – 79.6). X-ray review was performed to assess scapular notching and Sirveaux score was used to grade extent of notching. 11 patients had Sirveaux grade 0, 5 had grade 1, 6 had grade 2, 12 had grade 3 and 8 had grade 4 notching. Intra-operative complications included 2 glenoid fractures. Post-operative complications included 2 acromion fractures and 2 episodes of subsidence with dislocation. None of the patients developed post operative haematoma. There was one episode of infection in one patient that required further surgery. Iteration of approach with increasing experience over the years will be discussed. Ours is the biggest series of reverse geometry prosthesis used for irreparable rotator cuff tear arthropathy published so far in the literature and our results have shown superior results in terms of improvement in function and complications. We conclude reverse geometry shoulder replacement provides reasonable improvement in pain and function in elderly population with massive cuff tear arthropathy of shoulder.

We present a retrospective review of 50 cases of cuff tear arthropathy treated over past seven years by the use of reverse geometry shoulder prosthesis. 98% follow-up was achieved with average follow up of 3.04 years. Mean age was 81.3 (SD 9.2) years, female to male ratio was 5:1 and seven patients had bilateral procedures. Pre-operatively patients were assessed with American Shoulder and Elbow Surgeons Scores (ASES) and Oxford Scores and pos-operatively with ASES, Oxford and Constant scores. SF36 score was used to assess functional health status. Mean pre-op ASES was 22.29 (95%CI: 9.1 – 37.9) and post-op ASES score was 65.2 (95%CI: 48.5 – 81.9), (P< 0.001, Paired t-test). Mean post-operative Oxford score was 27.25 (95% CI: 18.4 – 27.6) and mean post operative Constant score was 63.2 (95% CI: 52.6 – 79.6). Sirveaux score was used to grade extent of glenoid notching on AP and lateral glenohumeral views, that showed 69% had notched. Complications included two acromion fractures, two episodes of subsidence with dislocation, one episode of infection and one patient with unexplained pain in axilla. We found reverse geometry shoulder replacement provides reasonable improvement in pain and function in elderly patients with massive cuff tear arthropathy.

We recommend reverse geometry shoulder replacement is the way forward to treat irreparable cuff tear arthropathy of shoulder.

There is debate regarding the most appropriate treatment of calcific tendinitis. Minimally-invasive techniques with image-guided needling of the deposits have been developed to provide an alternative solution. We present the results of fluoroscopically-guided barbotage in 100 patients. One hundred patients with acute or chronic shoulder pain, visible on plane radiographs or ultrasound scan, were referred from the Orthopaedic Department for barbotage over a six-year period. This study is a retrospective review of the results of barbotage in these patients, using a patient-based questionnaire. Forty three patients ultimately required arthroscopy of their painful shoulder. However, at surgery, the calcific deposits were noted to have dispersed in the majority of these patients. In addition there was often a long symptom-free period between the initial barbotage and recurrence of pain. In many cases the nature of their symptoms had changed and at arthroscopy signs of impingement or rotator cuff tears were common. Barbotage eliminated the need for more invasive surgery in over half of the patients in this study. It should be considered in all patients with calcific tendinitis refractory to non-operative treatment.

Collecting outcome scores in paper form is fraught with difficulty. We have assessed the feasibility of and patient’s attitude towards entering scores using a touchscreen.

A touchscreen was installed in the orthopaedic outpatient clinic. If relevant, patients were asked to complete either an Oswestry Disability Index (ODI) or Oxford Shoulder Score (OSS) using the screen. Patients were given written instructions and their hospital number by the receptionist who had no further input. Scores were completed with two identifiers. A paper questionnaire was used to assess computer experience and attitude towards the touchscreen.

Results: 1377 patients, average age 51 successfully completed a score in the first 12 months. 1/3 were over 60. 93% correctly entered their hospital number and date of birth, falling to 85% in patients over 70. All patients were identifiable. The average time to complete the scores was 4 minutes rising with age.

Of 170 patients completing the questionnaire, 1/3 had little or no experience of computers and 1/3 were over 60. 93% of patients were willing to repeat the score using the touchscreen to monitor progress. 2/3 found it easier to use than expected. Only 10% would prefer a paper score. These results were maintained among patients over 60. Only 2 were unable to complete the score and 80 % of those potentially eligible did so. The remainder were called to clinic before the touchscreen was free.

Conclusion: Orthopaedic outcome scores can be collected in very large volumes using a touchscreen. Data is then in an immediately usable form. The method is acceptable to the patients, independent of age and computer experience. Even in the oldest patients the accuracy is higher than for paper versions of the score. Combined with operative data, this simple method has the potential to provide a very powerful audit tool indeed.

One of the major long term problems of total shoulder replacement is loosening of the glenoid component. Since 1997 we have been using atmospheric pressure to drive cement into the interstices of the glenoid trabecular bone by lowering the intraosseous pressure. This is achieved by introducing a wide bore needle into the base of the coracoid process and attaching it to surgical suction. During this period approximately 200 Tornier Aequalis shoulder replacements were performed by the senior author. For the purpose of this detailed study 20 consecutive cases were studied.

Good exposure of the glenoid is achieved using an extended approach and aggressive surgical releases. The surface is prepared according to the manufacturers recommendation. The base of the coracoid is now exposed and drilled with a 3.5mm AO drill bit, angled so as not to collide with the keel of the glenoid component. A Verres needle is hammered into the glenoid at this point and connected to a separate, second suction apparatus, placed on high suction during final lavage, cement insertion and cement curing. Blood and lavage fluid can be seen to be sucked from the glenoid during preparation and cementation.

Standard true antero-posterior radiographs were taken by the same experienced radiographer in the plane of the glenoid face two days following surgery, and at 3 months and one year. A Mitotoyu digital microcalliper with a resolution of 0.1mm was used to determine the depth of cement intrusion and presence of lucent lines. Three independent observers measured each radiograph. Analysis of interobserver error shows agreement between observers. For assessment the glenoid was divided into five zones – Superior flange; superior slope of keel; base of keel; inferior slope of keel; inferior flange.

No patient had a complete lucent line around the glenoid component. Four patients had a single zone lucent line (ranging from 1.1mm to 1.7mm) None of these patients had a lucent line around the keel, and those four areas of lucency under the superior or inferior flange were more likely due to incomplete removal of articular cartilage than a failure of cement technique.

The reported prevalence of glenoid lucent lines varies from 22% to 89%. The significance of glenoid lucent lines is controversial but several studies have reported a direct relationship between the presence of radiolucent lines and the development of loosening of cemented components.

Secure cement technique is more difficult in the shoulder than in the knee or hip. Access is tighter, bleeding more difficult to control and peroxide should not be contemplated because of close proximity of the axillary nerve to the glenoid. Classic socket pressurisers can not fit into such a small space. We have found that the second sucker technique is extremely effective in establishing a secure cement-bone interface during glenoid replacement.

Development of a novel technique of arthroscopic rotator cuff repair which adapts the proven strong open technique using the Arthrex Post (low profile screw) into an arthroscopic technique by using the Arthrex Biotenodesis screw technique. The theoretical advantages of this technique are the ability to use stronger suture material, with a simple, tolerant, knotless and adaptable technique

Prior to use of this technique on patients we required laboratory confirmation of its benefit over present techniques. We have previous experience with laboratory testing at Exeter University using a MONSANTO TEN-SIOMETER for the previous Arthrex Post system. A similar experimental model was used for this study comparing two methods of fixation:

standard arthroscopic technique with Corkscrew anchor to decorticated footprint area on fresh frozen porcine humerus.

Initial results show a significant advantage of the biotenodesis technique with failure at over 1,000 N compared to 113N for a 2cm bone tunnel and 180N–600N for anchors. This shows promise for use in patients.

Purpose: To audit the improvement in function gained in patients with cuff tear arthropathy (CTA) using the reversed geometry delta 3 prosthesis and to balance this against operative and postoperative complications encountered.

Method: 20 consecutive patients with CTA were assessed using the ASES and Constant scores pre and postoperatively.

Results: All patients reported a marked improvement in post-operative pain relief. Average elevation increased from 49° to 102°. Function improved significantly. On the downside this is a technically difficult procedure in a group of patients whose average age was 81 (73–91) but whose biological age was higher. Technical difficulties arise from access to the glenoid, in particular to the inferior margin of the glenoid through a deltoid splitting approach. For this reason the surgical approach was changed to an extended deltopectoral approach with a large inferior capsular release after looping the axillary nerve. There was one death (not related to surgery), one acromial fracture, 2 glenoid fractures, 3 postoperative anaemias requiring transfusion, one postoperative hyponatraemia, one myocardial infarct and one pneumonia. These are severe complications for octogenarians to endure.

Conclusions: This is a technically demanding procedure with a heavy burden of complications for the surgeon and octogenarian patient to endure. However results in terms of postoperative pain relief and improvement in function have proved worthwhile to 19 of 20 patients.

Purpose: Can a surgeon use a Sonosite Ultrasound scanner to provide a one stop clinic, accurately detect cuff pathology and reduce delay from 8 months to same day?

Method: A surgeon, who had been involved in the development of shoulder ultrasound since 1984, personally purchased a 10MHz Sonosite scanner for his shoulder clinic.

Results: 191 scans were performed in 6 months; 111 to detect a cuff tear; 23 for impingement; 13 postoperatively; 8 for calcific tendonitis and 8 for biceps problems. 50 scans showed a normal cuff. 141 abnormal scans showed multiple abnormalities; 72 bicipital, 15 subscapular and 309 changes in supraspinatus. Of the supra-spinatus abnormalities 48 had irregular bone, 46 focal concavities, 36 focal discontinuity and 39 excess fluid in the bursa. Ultrasound was helpful in 168 patients, unhelpful in 23 of which 8 were unsatisfactory scans due to obesity, muscle or postoperative changes. Of the 168 helpful scans a change in diagnosis was made in 19, confirmatory abnormality in 99 and normality in 50.

Conclusion:

Surgeons can use ultrasound with confidence, the Sonosite scanner is accurate at detecting full thickness tears, calcifications may be over-reported. LHB can be assessed beyond the reach of arthroscopy and 191 patients have avoided an 8 month wait for a ten minute procedure. However the surgeon was placed under extreme duress by the radiology department attempting to block him from improving his service.

This study aimed to A) establish a protocol for measuring periprosthetic bone mineral density (BMD) of the proximal humerus following implant arthroplasty, and B) compare the differences in the periprosthetic BMD values 4–9 years after surface replacement and stemmed arthroplasties of the proximal humerus. The study design was of retrospective independent samples cohorts, of patients who had received a proximal humeral arthroplasty between January 1992 and December 1996 in a tertiary referral shoulder unit of a UK hospital. The exclusion criteria were A) patient unavailable for study, B) patient refusal, C) inadequate information of dependent and independent variables, or D) obvious measurement errors.

All available patients underwent DEXA scanning of the proximal humerus using a Lunar DPXL scanner fitted with Orthopaedic Hip software version 1.3. Replicable patient positioning with a special jig was used. On a predetermined format of Gruen equivalent zones and sub-zones, BMD values in gm/cm² were plotted. Cortical thickness on plain radiographs was recorded for each zone. Femoral neck DEXA scan was performed to obtain a proportionate value of BMD of the proximal humerus, in order to eliminate the effect of confounding variables. Confounding variables accounted for were age, gender, height, weight, activity level, indication for surgery, duration of implantation, dominance, type of arthroplasty (hemi or total) and use of cemented or uncemented stemmed implants. Statistical analysis was performed using Microsoft excel as well as SPSS software.

Initially, 58 shoulders in 52 patients were recruited. 6 patients declined to participate for ill health, 6 had moved out of the area and 8 did not attend or reply. Of the remaining 31 shoulders in 25 patients, 2 patients had an obviously erroneous DEXA reading. 29 shoulders in 23 patients were finally analysed, which included 10 male and 19 female shoulders. Average age was 67.5 years and average time since surgery was 6 years 2 months. Indications for surgery were RA in 14, OA in 8 and other reasons in 7. Of 29 shoulders, 20 received a total replacement, 9 a hemiarthroplasty.

The inevitable obliquity of the image caused some difficulties in maintaining accuracy and difficulties were observed due to limitation of the software to measure thin cortices and to distinguish between the cement and bone. There was no significant correlation between gross cortical thickness and BMD values, and the average periprosthetic BMD was 0.54 g/cm². Surface replacement implants were associated with relative preservation of proximal medial cortex and higher BMD values in this region. BMD values were consistently higher at the level of stem tip for the stemmed implants. No such phenomenon was observed for the surface replacement prostheses. Hemiarthroplasty was associated with relatively higher BMD values in the proximal medial cortical region than total arthroplasty.

The purpose of this study was to assess the clinical outcome of two non-invasive techniques used in the treatment of calcific tendinitis of the shoulder.

Over the eight month period April 2000 to November 2000 sixty patients who were referred to this hospital with symptomatic calcific tendonitis were treated either with extracorporeal shockwave therapy (ESWT) using the Storz Medical Minilith (Storz Medical AG, Kreuzlingen, Germany) or by barbotage (needle puncture, aspiration and lavage under ultrasound control). All the patients had a long history of shoulder pain (average 42 months), caused by a radiographically evident calcific deposit, that had been unresponsive to conservative treatment including physiotherapy, steroid injections and non-steroidal anti-inflammatory tablets.

15 patients were treated with ESWT and 45 with ultrasound guided barbotage. The patients undergoing ESWT had the application head positioned under real time ultrasound or flouroscopic control. Patients had from one to three treatments with up to 2,500 shocks per treatment at incremental energy levels from 0.1 to 0.2 mJ/ mm2. Patients undergoing real time ultrasound guided barbotage had a single treatment. Clinical outcome was evaluated after a three month period with a postal questionnaire.

Thirty-two of 45 patients (71%) in the barbotage group had a marked reduction in symptoms at three months compared to nine out of 15 (64%) of the ESWT group.

Shockwave therapy (ESWT) and ultrasound guided barbotage are simple non invasive outpatient procedures which are effective in 64% to 71% of patients. These simple outpatient techniques should be considered for chronic pain due to calcific deposits that have been unresponsive to conservative treatments, and surgery reserved for those who fail to benefit.
