The aim of this study was to assess the sensitivity of distal biceps hook test – O’Driscoll hook test – in a retrospective series of acute and chronic distal biceps tendon tears and investigate the ability of the test to predict the need for graft reconstruction.
We retrospectively evaluated 234 consecutive distal biceps tendon tears operated in a single centre. The result of O’Driscoll hook test and perioperative findings of distal biceps were documented in standard fashion.
The perioperative and O’Driscoll hook test data were available in 202 cases. The sensitivity for the distal biceps hook test was 78% in all tears and 83% in complete tears. The sensitivity was significantly lower in partial tears (30%) and in cases where lacertus fibrosus was found to be intact (45 %). When O’Driscoll hook test was positive and the delay from initial injury to operative intervention was eight weeks or more, there was over 75% probability of achilles tendon allograft reconstruction. When O’Driscoll hook test was negative, the probability of reconstruction even after 12 weeks’ delay was only 20%.
O’Driscoll hook test is useful when establishing distal biceps tendon tear diagnosis, but a negative test does not exclude rupture. In delayed cases, a positive test may predict the need for reconstruction.

To report a case series of three patients with septic arthritis of the acromioclavicular joint and a review of the literature for this condition. Additionally, we developed an algorithm for diagnosing and treating septic arthritis of the acromioclavicular joint.
A retrospective review of patients treated at our institution for septic arthritis of the acromioclavicular joint during the collection period was performed and three cases were identified. A review of the English literature on this rare condition was also performed with only 28 cases being identified.
A series of three consecutive patients were treated for septic acromioclavicular arthritis with resolution of the infection. Two patients underwent open surgical debridement and one underwent aspiration. All patients were treated with a minimum of six weeks of tailored intravenous antibiotic therapy.
Septic arthritis of the acromioclavicular joint can be difficult to diagnose and requires a high index of suspicion. Surgical debridement, open or arthroscopic, with tailored antibiotic therapy is an effective means for the management of septic arthritis of the acromioclavicular joint. In patients who are unable to have surgical debridement, aspiration and tailored antibiotics have been shown to be effective.

A resorbable subacromial balloon has been developed to address humeral head migration following posterosuperior rotator cuff tears. Entinostat mouse The purpose of this experimental assessment was to quantify the effect of balloon augmentation on humeral head position.
Eight cadaveric shoulders were subjected to 0°, 30°, 60° and 90° of abduction via a shoulder simulator. The deltoid was activated at 40N, then 80N. The subscapularis and infraspinatus with teres minor were then applied independently and together to create four muscle activation states for each deltoid load. The shoulder was tested intact, torn, then with the balloon. The centre of the humeral head was tracked using active optical markers.
When the rotator cuff was torn, the humeral head translated superior by 1.4 ± 1 mm overall (P = 0.009). Following balloon augment, the humeral head translated inferiorly by 2 ± 2 mm relative to the intact state (P = 0.042), and significantly more anterior than the intact (3 ± 2 mm; P = 0.005) state. Rotator cuff variation was only significantly different when the balloon was used, with the subscapularis translating the humeral head posteriorly (P = 0.006).
The subacromial balloon inferiorized the humeral head compared to the torn state. Unexpected anterior humeral head translation was attributed to the posterosuperior balloon placement relative to the humeral head.

Partial articular sided rotator cuff tears are described as being a common cause of shoulder pain and to have a significant impact of patient quality of life. The natural history of partial articular supraspinatus tendon avulsion lesions is not clearly defined and there is limited evidence to determine optimal management.
To perform a systematic review of the literature regarding the evidence for partial articular supraspinatus tendon avulsion repair and to determine whether there is any difference between operative and non-operatively managed patients.
Conventional and grey literature were searched with defined terms to identify studies in human adults concerning management of partial articular sided supraspinatus avulsions.
Out of 86 papers identified by the search terms, 28 were deemed eligible for review including 1966 shoulders. 4/28 papers were of level I-II evidence but all were comparing techniques. 4/28 papers were biomechanical cadaveric studies, assessing strength of repair and effect on stproducible. There are limited controlled studies to determine whether partial articular supraspinatus tendon avulsion lesions require repair. Current classification systems represent a single plane and are open to user variation. No evidence exists to determine which tears are stable and which may progress.
