Long-term clinical outcomes of arthroscopic supraspinatus tendon repair using the single anchor tension band technique - Minimum 5-years follow-up.

Background: The primary aim of this study was to assess the long-term patient reported outcomes of arthroscopic rotator cuff tear (ARCR) using a single anchor tension band (TB) technique for small and medium supraspinatus tears at minimum 5-years follow-up. Methods: A retrospective cohort study of consecutive ARCRs of small and medium supraspinatus tears using a knotless single anchor TB technique with minimum 5-year follow-up was carried out. Outcomes of interest included: range of motion (ROM) on examination under anaesthesia (EUA), visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) scores, Oxford Shoulder Score (OSS) and Short-Form (SF-12). Results: From 243 consecutive ARCR procedures, 82 patients with a mean age of 55 ± 9.5 years met the inclusion criteria at 6.7 ± 1.5 years follow-up. There were significant improvements in VAS (5.5 ± 2.2 vs. 0.7 ± 1.5), ASES (47.6 ± 16.8 vs. 92.8 ± 13.0), OSS (31.3 ± 7.2 vs. 45.3 ± 3.5) and SF-12 (37.6 ± 7.6 vs. 50.3 ± 7.7) post-operatively (all p < 0.001). Conclusions: The single anchor TB ARCR technique has excellent patient reported outcomes at a minimum of 5 years and is suitable for supraspinatus tears smaller than 20 mm in the sagittal plane. Level of evidence: Level IV; Consecutive Case Series.

The Relevance of Open Rotator Cuff Repair in 2021.

BACKGROUND: The last decade has seen a large increase in rotator cuff surgery and arthroscopic surgery. We were asked to define the relevance of open rotator cuff repair in 2021. PURPOSE: To define whether there are proven advantages to arthroscopic or open rotator cuff repair surgery. METHOD: We reviewed the recent literature regarding recent trends, anaesthetic time, rehabilitation, post-operative pain, complications, economic considerations, the learning curve and outcomes. We outlined the senior authors' technique preferences, rationale and patient reported outcomes. RESULTS: There is no clear evidence of proven advantage in arthroscopic rotator cuff repair compared to open rotator cuff repairs, with regard to outcomes or the other aspects reviewed. There were no differences in the outcomes of arthroscopic and open repairs in the senior authors practice with his procedure indications. CONCLUSIONS: Open rotator cuff repair surgery remains a valid option and has some appeal in specific indications and in settings where arthroscopic resources are limited. We believe surgeons should learn both techniques and the principles of good patient selection, tissue handling, and fixation techniques are of paramount importance in both arthroscopic and open rotator cuff surgery.

Hand Surgery in New Zealand.

Hand surgery in New Zealand has steadily grown from its origins in plastic surgery and orthopaedic surgery into its own discipline. There has been much progress and innovation in hand surgery that has originated from New Zealand and this review acknowledges the historical figures and events that have led to our present position. The current and future directions of hand surgery in our country are also discussed. As a small and remote country, we are very fortunate to have close relationships with other international hand societies. Through these relationships and the efforts of committed regional hand surgeons, the art and science of hand surgery in New Zealand continues to progress.

Does the Beighton Score Correlate With Specific Measures of Shoulder Joint Laxity?

BACKGROUND: Evaluation of shoulder joint laxity is an important component of the shoulder examination, especially in the setting of shoulder instability. Measures of generalized joint laxity, particularly the Beighton score, are often recorded and used to help make management decisions in these cases. However, no evidence is available to show that the Beighton score corresponds to specific measures of shoulder joint laxity. PURPOSE: To assess the correlation between the Beighton score and validated measures of shoulder joint laxity. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: A total of 160 participants (age range, 16-35 years) with no history of shoulder joint abnormality were examined. The Beighton score, glenohumeral external rotation (standing and lying), glenohumeral abduction, and the sulcus sign were recorded. The relationship between the Beighton score and each measure of shoulder joint laxity was assessed. RESULTS: A high proportion of participants (34%) had a Beighton score of 4 or higher. Rates of positive shoulder laxity tests were lower (11%-19%). A positive Beighton score was a poor predictor of abnormal shoulder laxity, with low sensitivity (range, 0.40-0.48) and low positive predictive values (range, 0.13-0.31). Spearman correlation coefficients demonstrated poor correlation between the Beighton score and all measures of shoulder joint laxity when assessed as continuous variables (range, 0.29-0.45). CONCLUSION: The Beighton score has poor correlation with specific measures of shoulder joint laxity and should not be considered equivalent to these tests as a method of clinical assessment.

A Comparative Outcome Study of Hamstring Versus Tibialis Anterior and Synthetic Grafts for Deltoid to Triceps Transfers.

PURPOSE: To assess elbow extension strength and complications after deltoid-triceps transfers using hamstring tendon graft compared with tibialis anterior and synthetic tendon grafts. METHODS: A retrospective review of deltoid-triceps transfers in patients with tetraplegia performed between 1983 and 2014. RESULTS: Seventy-five people (136 arms) had surgery performed, with the majority undergoing simultaneous bilateral surgery (n = 61; 81%). Tibialis anterior tendon grafts were used in 68 arms, synthetic grafts in 23 arms, and hamstring tendon grafts in 45 arms. The average age at surgery was 31 years. Sixty-three arms (46%) were assessed between 12 and 24 months after surgery. Seventy percent of the group (n = 54) were able to extend their elbow against gravity (grade 3 of 5 or greater) following surgery. Seventy-nine percent of those with hamstring grafts achieved grade 3 of 5 or more compared with 77% with tibialis anterior and 33% with synthetic grafts. There was a statistically significant difference in postsurgery elbow extension between the tibialis anterior group and the synthetic graft group and the hamstring and the synthetic graft group but not between the tibialis anterior and the hamstring group. Complications occurred in 19 arms (14%), the majority occurring immediately after surgery and associated with the wounds. The remaining complications were with the synthetic graft group in which dehiscence of the proximal attachment occurred in 30% of the arms. CONCLUSIONS: Autologous tendon grafting is associated with achievement of antigravity elbow extension in a greater proportion of individuals than with prosthetic grafting. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Shoulder pain in primary care: frozen shoulder.

BACKGROUND AND CONTEXT Frozen shoulder is a painful condition that follows a protracted clinical course. We aim to review the management of patients with a diagnosis of frozen shoulder who are referred for specialist orthopaedic evaluation against existing guidelines in primary care. ASSESSMENT OF PROBLEM Referrals and clinical records were reviewed for all patients referred for orthopaedic specialist assessment who received a specialist diagnosis of frozen shoulder. Diagnostic, investigation and management practices from a regional primary health care setting in New Zealand were compared with guideline-recommended management. RESULTS Eighty patients with frozen shoulder were referred for orthopaedic evaluation in the 13 month study period, mostly from general practice. Fifteen patients (19%) were identified as having a frozen shoulder in their medical referral. Most (99%) had received previous imaging. Seven patients (12%) had received guideline recommended treatment. STRATEGIES FOR IMPROVEMENT Education of all clinicians involved in patient management is important to ensure an understanding of the long natural history of frozen shoulder and provide reassurance that outcomes are generally excellent. HealthPathways now include more information regarding diagnosis, imaging and evidence-based management for frozen shoulder. LESSONS Frozen shoulder may be under-diagnosed among patients referred for orthopaedic review. Ultrasound imaging is commonly used and may identify occult and unrelated pathology in this age-group. When managed according to clinical guidelines, patients report significant clinical and functional improvement with most reporting 80% function compared with normal after 1 year.

Tendon Transfer Surgery for People With Tetraplegia: An Overview.

After cervical spinal cord injury, the loss of upper limb function is common. This affects an individual's ability to perform activities of daily living and participate in previous life roles. There are surgical procedures that can restore some of the upper limb function lost after cervical spinal cord injury. Tendon transfer surgery has been performed in the tetraplegic population since the early 1970s. The goals of surgery are to provide a person with tetraplegia with active elbow extension, wrist extension (if absent), and sufficient pinch and/or grip strength to perform activities of daily living without the need for adaptive equipment or orthoses. These procedures are suitable for a specific group, usually with spinal cord impairment of C4-8, with explicit components of motor and sensory loss. Comprehensive team assessments of current functioning, environment, and personal circumstances are important to ensure success of any procedure. Rehabilitation after tendon transfer surgery involves immobilization for tendon healing followed by specific, targeted therapy based on motor learning and goal-orientated training. Outcomes of tendon transfer surgery are not limited to the improvements in an individual's strength, function, and performance of activities but have much greater life affects, especially with regard to well-being, employment, and participation. This article will provide an overview of the aims of surgery, preoperative assessment, common procedures, postoperative rehabilitation strategies, and outcomes based on clinical experience and international published literature.

Type IV acromioclavicular joint dislocation associated with a mid-shaft clavicle malunion.

This reports presents the case of a combined clavicle fracture malunion and chronic Type IV acromioclavicular (AC) joint dislocation. The patient was seen acutely in the emergency department following a mountain bike accident at which time the clavicle fracture was identified and managed conservatively however the AC dislocation was not diagnosed. The patient presented 25 months following the injury with persistent pain and disability and was treated with clavicle osteotomy and AC stabilization. We document the clinical details, surgical treatment and outcome.

Morphology of the humeral insertion of the supraspinatus and infraspinatus tendons: Application to rotator cuff repair.

In shoulder surgery, a precise understanding of anatomical relationships is required for accurate reconstruction. Reports in recent literature have challenged the traditional definitions of the humeral footprints of the supraspinatus and infraspinatus tendons. This study aims to precisely delineate these footprints. The rotator cuffs of 54 shoulders from 27 Australian Caucasoid donor cadavers were examined. The tendinous portions were dissected down to their region/footprint of attachment upon the humerus. Measurements of those footprints, upon the greater and lesser tuberosities, were made. Those measurements were statistically analyzed for any association with age, sex, height, or side. Twenty-seven cadavers had an average age at death of 74.9 (± 12.8), 56% were male, average height was 168 (± 8.6) cm. Due to premorbid fracture, or degeneration, 11 shoulders were excluded. The footprint of the supraspinatus was triangular, with a medial, anteroposterior length of 20.4 ± 4.2 mm. Its lateral anteroposterior length was 6.3 ± 1.6 mm and its maximal mediolateral width was 6.6 ± 2.7 mm. Its calculated area was 122.0 ± 66.6 mm(2). The footprint of the infraspinatus was trapezoidal, with a medial anteroposterior length 22.6 ± 3.0 mm. Its lateral anteroposterior length was 25.4 ± 3.3mm and its maximal mediolateral width was 12.0 ± 2.7 mm. Its calculated area was 294.9 ± 74.1 mm(2). There was no statistical correlation between size of the footprint and age, sex, side, or height. The humeral footprints of the supraspinatus and infraspinatus tendons upon the greater tuberosity were distinct. The lateral border of the infraspinatus' humeral attachment extended much farther anteriorly upon the highest facet of the greater tuberosity than in traditional descriptions.

The effects of aging on upper limb tendon transfers in patients with tetraplegia.

PURPOSE: To evaluate the effects of aging on hand function among patients with tetraplegia who had forearm tendon transfer surgery between 1982 and 1990. METHODS: The study used a longitudinal cohort design that compared hand function outcomes in 2012 with those obtained 11 years earlier. A digital analyzer was used to measure key pinch and grip strength, and results were compared with those obtained in 2001 to determine changes in strength over time. The study also evaluated changes in participant's employment status, wheelchair use, and subjective changes in function using the Lamb and Chan questionnaire. RESULTS: Participants had a mean key pinch strength force between 11.5 N (tenodeses) and 32.9 N (active transfers) and grip strength forces between 23 N (tenodeses) and 59 N (active transfers). Since 2001, people with active transfers either maintained strength or experienced decreased strength of 5% to 14%. Thumb tenodesis power decreased 40% to 51%, whereas finger tenodeses power increased 32% to 70%. Three activities in the Lamb and Chan questionnaire were identified by the majority of participants as being worse or much worse over the past 11 years. These were performing a pressure relief and propelling a manual wheelchair on level ground and up a ramp. These findings correspond with the increased number of participants who used a power wheelchair in 2012 (64%) compared with 2001 (26%). Close to half of the participants (46%) were employed compared with the 90% in 2001. CONCLUSIONS: Tendon transfers continued to provide pinch and grip function for individuals with tetraplegia for many years following spinal cord injury. The decrease in strength of those with active transfers over the 11-year period was within the reported aging loss for the normal population. The small number of participants with tenodesis, however, limited our ability to draw meaningful conclusions for this group. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic III.

A review of national shoulder and elbow joint replacement registries.

BACKGROUND: The aim was to review the funding, organization, data handling, outcome measurements, and findings from existing national shoulder and elbow joint replacement registries; to consider the possibility of pooling data between registries; and to consider wether a pan european registry might be feasible. MATERIALS AND METHODS: Web sites, annual reports, and publications from ongoing national registries were searched using Google, PubMed, and links from other registries. Representatives from each registry were contacted. RESULTS: Between 1994 and 2004, 6 shoulder registries and 5 elbow registries were established, and by the end of 2009, the shoulder registries included between 2498 and 7113 replacements and the elbow registries between 267 and 1457 replacements. The registries were initiated by orthopedic societies and funded by the government or by levies on implant manufacturers. In some countries, data reporting and patient consent are required. Completeness is assessed by comparing data with the national health authority. All registries use implant survival as the primary outcome. Some registries use patient-reported outcomes as a secondary outcome. CONCLUSIONS: A registry offers many advantages; however, adequate long-term funding and completeness remain a challenge. It is unlikely that large-scale international registries can be implemented, but more countries should be encouraged to establish registries and, by adopting compatible processes, data could be pooled between national registries, adding considerably to their power and usefulness.

Upper limb surgery for tetraplegia: a 10-year re-review of hand function.

PURPOSE: To perform a 10-year re-review of hand function outcome for 24 tetraplegic persons who had received bilateral tendon transfers and tenodeses. METHODS: The Lamb and Chan questionnaire with additional questions, the Quadriplegic Index of Function (QIF), the Swanson sphygmomanometer technique for hook grip, the Preston Pinch Meter (PP) for key pinch, and a digital analyzer (DA) for both hook and key pinch were the test instruments used. The QIF and DA had not been used previously. RESULTS: Levels of functional independence and expectations were maintained. Mean hook grip values were maintained for the right hand but increased significantly for the left to reach right hand values. Mean pinch grip values decreased significantly. DA measurements confirmed similar hook grip values for both hands but key pinch values were significantly higher than the PP values. Active transfers averaged approximately twice the strength of tenodeses. CONCLUSIONS: Hand function improvements gained from tendon transfers and tenodeses are maintained over time.

Optimizing the radiographic technique in clavicular fractures.

The purpose of this study was to assess the accuracy and utility of the posteroanterior (PA) 15 degrees caudad view of the clavicle to assess shortening of clavicular fractures. The first stage involved taking radiographs of an adult skeleton, centered on the clavicle, with the standard anterosuperior 15 degrees cephalad view and the PA 15 degrees caudad view. Additional images were taken in the 15 degrees caudad view with a series of oblique rotational views and oblique images in the vertical plane. Metal markers were placed on the clavicle at 10-mm intervals. Clavicular length and the interval between markers were measured on the radiographs. The second stage involved obtaining the PA 15 degrees caudad radiograph in 50 patients with clavicular fractures. The noninjured clavicle also underwent radiography. The lengths of the noninjured clavicle and of the fragments of the fractured clavicle were recorded. The length of the skeletal clavicle in the standard anterosuperior image was 149 mm, with up to 19 mm of variation on oblique views. The length in the PA 15 degrees caudad image was 130 mm, with a maximum of 4 mm of variation on the oblique views up to 30 degrees. The true length of the skeletal clavicle was 124 mm. Forty-five fractures were diaphyseal, and five were outer-third fractures. There was less than 5 mm of measured difference in the length of injured and noninjured clavicles in 38 of 45 patients with diaphyseal fractures (84%). We have identified a more accurate technique for the assessment of fractures of the clavicle in evaluating length and clavicular alignment. The PA 15 degrees caudad clavicle radiograph technique is well tolerated by patients.
