Favourable short-term outcomes have been reported following latissimus dorsi tendon transfer for patients with an irreparable subscapularis (SSC) tendon tear. The aim of this study was to investigate the long-term outcomes of this transfer in these patients. This was a retrospective study involving 30 patients with an irreparable SSC tear and those with a SSC tear combined with a reparable supraspinatus tear, who underwent a latissimus dorsi tendon transfer. Clinical scores and active range of motion (aROM), SSC-specific physical examination and the rate of return to work were assessed. Radiological assessment included recording the acromiohumeral distance (AHD), the Hamada grade of cuff tear arthropathy and the integrity of the transferred tendon. Statistical analysis compared preoperative, short-term (two years), and final follow-up at a mean of 8.7 years (7 to 10).Aims
Methods
Rotator cuff pathology is the main cause of shoulder pain and dysfunction in older adults. When a rotator cuff tear involves the subscapularis tendon, the symptoms are usually more severe and the prognosis after surgery must be guarded. Isolated subscapularis tears represent 18% of all rotator cuff tears and arthroscopic repair is a good alternative primary treatment. However, when the tendon is deemed irreparable, tendon transfers are the only option for younger or high-functioning patients. The aim of this review is to describe the indications, biomechanical principles, and outcomes which have been reported for tendon transfers, which are available for the treatment of irreparable subscapularis tears. The best tendon to be transferred remains controversial. Pectoralis major transfer was described more than 30 years ago to treat patients with failed surgery for instability of the shoulder. It has subsequently been used extensively to manage irreparable subscapularis tendon tears in many clinical settings. Although
Multiple secondary surgical procedures of the shoulder, such as soft-tissue releases, tendon transfers, and osteotomies, are described in brachial plexus birth palsy (BPBP) patients. The long-term functional outcomes of these procedures described in the literature are inconclusive. We aimed to analyze the literature looking for a consensus on treatment options. A systematic literature search in healthcare databases (PubMed, Embase, the Cochrane library, CINAHL, and Web of Science) was performed from January 2000 to July 2020, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The quality of the included studies was assessed with the Cochrane ROBINS-I risk of bias tool. Relevant trials studying BPBP with at least five years of follow-up and describing functional outcome were included.Aims
Methods
Upper limb amputations, ranging from transhumeral to partial hand, can be devastating for patients, their families, and society. Modern paradigm shifts have focused on reconstructive options after upper extremity limb loss, rather than considering the amputation an ablative procedure. Surgical advancements such as targeted muscle reinnervation and regenerative peripheral nerve interface, in combination with technological development of modern prosthetics, have expanded options for patients after amputation. In the near future, advances such as osseointegration, implantable myoelectric sensors, and implantable nerve cuffs may become more widely used and may expand the options for prosthetic integration, myoelectric signal detection, and restoration of sensation. This review summarizes the current advancements in surgical techniques and prosthetics for upper limb amputees. Cite this article:
The aim of this study was to determine the current incidence and epidemiology of humeral diaphyseal fractures. The secondary aim was to explore variation in patient and injury characteristics by fracture location within the humeral diaphysis. Over ten years (2008 to 2017), all adult patients (aged ≥ 16 years) sustaining an acute fracture of the humeral diaphysis managed at the study centre were retrospectively identified from a trauma database. Patient age, sex, medical/social background, injury mechanism, fracture classification, and associated injuries were recorded and analyzed.Aims
Methods
Conservative treatment of moderately displaced proximal humeral head fractures yields good clinical results, but secondary fragment displacement may occur. Identification of those fractures at risk of displacement may influence initial decision-making. A total of 163 shoulders in 162 patients with conservatively treated isolated proximal humeral fractures were included. The fractures occurred between January 2015 and May 2018. The mean age of the patients was 69 years (26 to 100) and the mean follow-up was 144 days (42 to 779). The fractures were classified according to Neer. Scores for osteoporosis (Tingart, Deltoid Tuberosity Index (DTI)) and osteoarthritis (OA) of the glenohumeral joint were assessed. Translation of the head on follow-up radiographs of more than 10 mm was defined as displacement. Eccentric head index (EHI) describes the offset of the humeral head centre in relation to the diaphyseal axis. The ratio was estimated on anteroposterior (AP) and Neer views. Medial hinge was considered intact if the medial cortex proximal and distal to the fracture was in line on AP view.Aims
Methods
To describe and analyze the mid-term functional outcomes of a large series of patients who underwent the Hoffer procedure for brachial plexus birth palsy (BPBP). All patients who underwent the Hoffer procedure with minimum two-year follow-up were retrospectively reviewed. Active shoulder range of movement (ROM), aggregate modified Mallet classification scores, Hospital for Sick Children Active Movement Scale (AMS) scores, and/or Toronto Test Scores were used to assess functional outcomes. Subgroup analysis based on age and level of injury was performed. Risk factors for subsequent humeral derotational osteotomy and other complications were also assessed. A total of 107 patients, average age 3.9 years (1.6 to 13) and 59% female, were included in the study with mean 68 months (24 to 194) follow-up.Aims
Methods
Restoring the pre-morbid anatomy of the proximal humerus is a
goal of anatomical shoulder arthroplasty, but reliance is placed
on the surgeon’s experience and on anatomical estimations. The purpose
of this study was to present a novel method, ‘Statistical Shape
Modelling’, which accurately predicts the pre-morbid proximal humeral anatomy
and calculates the 3D geometric parameters needed to restore normal
anatomy in patients with severe degenerative osteoarthritis or a
fracture of the proximal humerus. From a database of 57 humeral CT scans 3D humeral reconstructions
were manually created. The reconstructions were used to construct
a statistical shape model (SSM), which was then tested on a second
set of 52 scans. For each humerus in the second set, 3D reconstructions
of four diaphyseal segments of varying lengths were created. These
reconstructions were chosen to mimic severe osteoarthritis, a fracture
of the surgical neck of the humerus and a proximal humeral fracture
with diaphyseal extension. The SSM was then applied to the diaphyseal
segments to see how well it predicted proximal morphology, using
the actual proximal humeral morphology for comparison.Aims
Materials and Methods
Radiostereometric analysis (RSA) allows an extremely accurate
measurement of early micromotion of components following arthroplasty. In this study, RSA was used to measure the migration of 11 partially
cemented fluted pegged glenoid components in patients with osteoarthritis
who underwent total shoulder arthroplasty using an improved surgical
technique (seven men, four women, mean age 68). Patients were evaluated
clinically using the American Shoulder and Elbow Surgeons (ASES)
and Constant-Murley scores and by CT scans two years post-operatively. Aims
Patients and Methods
To assess complications and failure mechanisms of osteoarticular
allograft reconstructions for primary bone tumours. We retrospectively evaluated 38 patients (28 men, 74%) who were
treated at our institution with osteoarticular allograft reconstruction
between 1989 and 2010. Median age was 19 years (interquartile range
14 to 32). Median follow-up was 19.5 years (95% confidence interval
(CI) 13.0 to 26.1) when 26 patients (68%) were alive. In addition, we
systematically searched the literature for clinical studies on osteoarticular
allografts, finding 31 studies suitable for analysis. Results of
papers that reported on one site exclusively were pooled for comparison.Aims
Patients and Methods
Aims. Despite the expansion of arthroscopic surgery of the shoulder,
the open deltopectoral approach is increasingly used for the fixation
of fractures and arthroplasty of the shoulder. The anatomy of the
terminal branches of the posterior circumflex humeral artery (PCHA)
has not been described before. We undertook an investigation to
correct this omission. Patients and Methods. The vascular anatomy encountered during 100 consecutive elective
deltopectoral approaches was recorded, and the common variants of
the terminal branches of the PCHA are described. Results. In total, 92 patients (92%) had a terminal branch that crossed
the space between the deltoid and the proximal humerus and which
was therefore vulnerable to tearing or avulsion during the insertion
of the blade of a retractor during the deltopectoral approach to
the shoulder. In 75 patients (75%) there was a single vessel, in
16 (16%) a double vessel and in one a triple vessel. Conclusion. The relationship of these vessels to the landmark of the tendon

We present the medium-term clinical results of a reverse total
shoulder arthroplasty with a trabecular metal glenoid base plate. We reviewed 125 consecutive primary reverse total shoulder arthroplasties
(RTSA) implanted in 124 patients for rotator cuff arthropathy. There
were 100 women and 24 men in the study group with a mean age of
76 years (58 to 89). The mean follow-up was 32 months (24 to 60).
No patient was lost to follow-up.Aim
Patients and Methods
Inherent disadvantages of reverse shoulder arthroplasty
designs based on the Grammont concept have raised a renewed interest
in less-medialised designs and techniques. The aim of this study
was to evaluate the outcome of reverse shoulder arthroplasty (RSA)
with the fully-constrained, less-medialised, Bayley–Walker prosthesis performed
for the treatment of rotator-cuff-deficient shoulders with glenohumeral
arthritis. A total of 97 arthroplasties in 92 patients (53 women
and 44 men, mean age 67 years (standard deviation ( The Bayley–Walker prosthesis provides reliable pain relief and
reasonable functional improvement for patients with symptomatic
cuff-deficient shoulders. Compared with other designs of RSA, it
offers a modest improvement in forward elevation, but restores external
rotation to some extent and prevents scapular notching. A longer
follow-up is required to assess the survival of the prosthesis and
the clinical performance over time. Cite this article:
We retrospectively reviewed the outcomes of 33
consecutive patients who had undergone an extra-articular, total or
partial scapulectomy for a malignant tumour of the shoulder girdle
between 1 July 2001 and 30 September 2013. Of these, 26 had tumours
which originated in the scapula or the adjacent soft tissue and
underwent a classic Tikhoff–Linberg procedure, while seven with
tumours arising from the proximal humerus were treated with a modified
Tikhoff-Linberg operation. We used a Ligament Advanced Reinforcement
System for soft-tissue reconstruction in nine patients, but not
in the other 24. The mean Musculoskeletal Tumor Society score (MSTS) was 17.6
(95% confidence interval (CI) 15.9 to 19.4); 17.6 (95% CI 15.5 to
19.6) after the classic Tikhoff–Linberg procedure and 18.1 (95%
CI 13.8 to 22.3) after the modified Tikhoff–Linberg procedure. Patients
who had undergone a LARS soft-tissue reconstruction had a mean score
of 18.6 (95% (CI) 13.9 to 22.4) compared with 17.2 (95% CI 15.5
to 19.0) for those who did not. The Tikhoff–Linberg procedure is a useful method for wide resection
of a malignant tumour of the shoulder girdle which helps to preserve
hand and elbow function. The method of soft-tissue reconstruction
has no effect on functional outcome. Cite this article:
Some surgeons are reluctant to perform a reverse
total shoulder arthroplasty (RTSA) on both shoulders because of concerns
regarding difficulty with activities of daily living post-operatively
as a result of limited rotation of the shoulders. Nevertheless,
we hypothesised that outcomes and patient satisfaction following
bilateral RTSA would be comparable to those following unilateral
RTSA. A single-surgeon RTSA registry was reviewed for patients who underwent
bilateral staged RTSA with a minimum follow-up of two years. A unilateral
RTSA matched control was selected for each shoulder in those patients
undergoing bilateral procedures. The Constant–Murley score (CMS), American
Shoulder and Elbow Surgeons (ASES) score, Subjective Shoulder Values
(SSV), visual analogue scale (VAS) for pain, range of movement and
strength were measured pre- and post-operatively. The mean CMS,
ASES, SSV, VAS scores, strength and active forward elevation were
significantly improved
(all p <
0.01) following each operation in those undergoing bilateral
procedures. The mean active external rotation (p = 0.63 and p =
0.19) and internal rotation (p = 0.77 and p = 0.24) were not significantly
improved. The improvement in the mean ASES score after the first
RTSA was greater than the improvement in its control group (p =
0.0039). The improvement in the mean CMS, ASES scores and active
forward elevation was significantly less after the second RTSA than
in its control group (p = 0.0244, p = 0.0183, and p = 0.0280, respectively).
Pain relief and function significantly improved after each RTSA
in those undergoing a bilateral procedure. Bilateral RTSA is thus a reasonable form of treatment for patients
with severe bilateral rotator cuff deficiency, although inferior
results may be seen after the second procedure compared with the
first. Cite this article:
The indications for reverse shoulder arthroplasty
(RSA) continue to be expanded. Associated impairment of the deltoid
muscle has been considered a contraindication to its use, as function
of the RSA depends on the deltoid and impairment of the deltoid
may increase the risk of dislocation. The aim of this retrospective
study was to determine the functional outcome and risk of dislocation
following the use of an RSA in patients with impaired deltoid function.
Between 1999 and 2010, 49 patients (49 shoulders) with impairment
of the deltoid underwent RSA and were reviewed at a mean of 38 months
(12 to 142) post-operatively. There were nine post-operative complications (18%),
including two dislocations. The mean forward elevation improved
from 50° ( These results suggest that pre-operative deltoid impairment,
in certain circumstances, is not an absolute contraindication to
RSA. This form of treatment can yield reliable improvement in function
without excessive risk of post-operative dislocation. Cite this article:
The sternoclavicular joint (SCJ) is a pivotal
articulation in the linked system of the upper limb girdle, providing
load-bearing in compression while resisting displacement in tension
or distraction at the manubrium sterni. The SCJ and acromioclavicular
joint (ACJ) both have a small surface area of contact protected
by an intra-articular fibrocartilaginous disc and are supported
by strong extrinsic and intrinsic capsular ligaments. The function
of load-sharing in the upper limb by bulky periscapular and thoracobrachial
muscles is extremely important to the longevity of both joints.
Ligamentous and capsular laxity changes with age, exposing both
joints to greater strain, which may explain the rising incidence
of arthritis in both with age. The incidence of arthritis in the
SCJ is less than that in the ACJ, suggesting that the extrinsic
ligaments of the SCJ provide greater stability than the coracoclavicular
ligaments of the ACJ. Instability of the SCJ is rare and can be difficult to distinguish
from medial clavicular physeal or metaphyseal fracture-separation:
cross-sectional imaging is often required. The distinction is important
because the treatment options and outcomes of treatment are dissimilar,
whereas the treatment and outcomes of ACJ separation and fracture
of the lateral clavicle can be similar. Proper recognition and treatment
of traumatic instability is vital as these injuries may be life-threatening.
Instability of the SCJ does not always require surgical intervention.
An accurate diagnosis is required before surgery can be considered,
and we recommend the use of the Stanmore instability triangle. Most
poor outcomes result from a failure to recognise the underlying
pathology. There is a natural reluctance for orthopaedic surgeons to operate
in this area owing to unfamiliarity with, and the close proximity
of, the related vascular structures, but the interposed sternohyoid
and sternothyroid muscles are rarely injured and provide a clear
boundary to the medial retroclavicular space, as well as an anatomical
barrier to unsafe intervention. This review presents current concepts of instability of the SCJ,
describes the relevant surgical anatomy, provides a framework for
diagnosis and management, including physiotherapy, and discusses
the technical challenges of operative intervention. Cite this article:
Despite the expansion of arthroscopic surgery
of the shoulder, the open deltopectoral approach to the shoulder
is still frequently used, for example in fracture fixation and shoulder
replacement. However, it is sometimes accompanied by unexpected
bleeding. The cephalic vein is the landmark for the deltopectoral
interval, yet its intimate relationship with the deltoid artery,
and the anatomical variations in that structure, have not previously been
documented. In this study the vascular anatomy encountered during 100 consecutive
elective deltopectoral approaches was recorded and the common variants
described. Two common variants of the deltoid artery were encountered.
In type I (71%) it crosses the interval and tunnels into the deltoid
muscle without encountering the cephalic vein. However, in type
II (21%) it crosses the interval, reaches the cephalic vein and
then runs down, medial to and behind it, giving off several small
arterial branches that return back across the interval to the pectoralis
major. Several minor variations were also seen (8%). These variations in the deltoid artery have not previously been
described and may lead to confusion and unexpected bleeding during
this standard anterior surgical approach to the shoulder. Cite this article:
Latissimus dorsi tendon transfer (LDTT) is technically
challenging. In order to clarify the local structural anatomy, we undertook
a morphometric study using six complete cadavers (12 shoulders).
Measurements were made from the tendon to the nearby neurovascular
structures with the arm in two positions: flexed and internally
rotated, and adducted in neutral rotation. The tendon was then transferred
and measurements were taken from the edge of the tendon to a reference
point on the humeral head in order to assess the effect of a novel
two-stage release on the excursion of the tendon. With the shoulder flexed and internally rotated, the mean distances
between the superior tendon edge and the radial nerve, brachial
artery, axillary nerve and posterior circumflex artery were 30 mm
(26 to 34), 28 mm (17 to 39), 21 mm (12 to 28) and 15 mm (10 to
21), respectively. The mean distance between the inferior tendon
edge and the radial nerve, brachial artery and profunda brachii
artery was 18 mm (8 to 27), 22 mm (15 to 32) and 14 mm (7 to 21), respectively.
Moving the arm to a neutral position reduced these distances. A
mean of 15 mm (8 to 21) was gained from a standard soft-tissue release,
and 32 mm (20 to 45) from an extensile release. These figures help to define further the structural anatomy of
this region and the potential for transfer of the latissimus dorsi
tendon. Cite this article:
Reverse total shoulder replacement (RTSR) depends
on adequate deltoid function for a successful outcome. However, the
anterior deltoid and/or axillary nerve may be damaged due to prior
procedures or injury. The purpose of this study was to determine
the compensatory muscle forces required for scapular plane elevation
following RTSR when the anterior deltoid is deficient. The soft
tissues were removed from six cadaver shoulders, except for tendon
attachments. After implantation of the RTSR, the shoulders were
mounted on a custom-made shoulder simulator to determine the mean
force in each muscle required to achieve 30° and 60° of scapular
plane elevation. Two conditions were tested: 1) Control with an
absent supraspinatus and infraspinatus; and 2) Control with anterior
deltoid deficiency. Anterior deltoid deficiency resulted in a mean
increase of 195% in subscapularis force at 30° when compared with
the control (p = 0.02). At 60°, the subscapularis force increased
a mean of 82% (p <
0.001) and the middle deltoid force increased
a mean of 26% (p = 0.04). Scapular plane elevation may still be possible following an RTSR
in the setting of anterior deltoid deficiency. When the anterior
deltoid is deficient, there is a compensatory increase in the force
required by the subscapularis and middle deltoid. Attempts to preserve
the subscapularis, if present, might maximise post-operative function.
