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
The aims of this study were to validate the minimal clinically important difference (MCID) and patient-acceptable symptom state (PASS) thresholds for Western Ontario Shoulder Instability Index (WOSI), Rowe score, American Shoulder and Elbow Surgeons (ASES), and visual analogue scale (VAS) scores following arthroscopic Bankart repair, and to identify preoperative threshold values of these scores that could predict the achievement of MCID and PASS. A retrospective review was conducted on 131 consecutive patients with anterior shoulder instability who underwent arthroscopic Bankart repair between January 2020 and January 2023. Inclusion criteria required at least one episode of shoulder instability and a minimum follow-up period of 12 months. Preoperative and one-year postoperative scores were assessed. MCID and PASS were estimated using distribution-based and anchor-based methods, respectively. Receiver operating characteristic curve analysis determined preoperative patient-reported outcome measure thresholds predictive of achieving MCID and PASS.Aims
Methods
The outcomes following nonoperative management of minimally displaced greater tuberosity (GT) fractures, and the factors which influence patient experience, remain poorly defined. We assessed the early patient-derived outcomes following these injuries and examined the effect of a range of demographic- and injury-related variables on these outcomes. In total, 101 patients (53 female, 48 male) with a mean age of 50.9 years (19 to 76) with minimally displaced GT fractures were recruited to a prospective observational cohort study. During the first year after injury, patients underwent experiential assessment using the Disabilities of the Arm, Shoulder and Hand (DASH) score and assessment of associated injuries using MRI performed within two weeks of injury. The primary outcome was the one-year DASH score. Multivariate analysis was used to assess the effect of patient demographic factors, complications, and associated injuries, on outcome.Aims
Methods
The open Latarjet procedure is a widely used treatment for recurrent anterior instability of the shoulder. Although satisfactory outcomes are reported, factors which influence a patient’s experience are poorly quantified. The aim of this study was to evaluate the effect of a range of demographic factors and measures of the severity of instability on patient-reported outcome measures in patients who underwent an open Latarjet procedure at a minimum follow-up of two years. A total of 350 patients with anterior instability of the shoulder who underwent an open Latarjet procedure between 2005 and 2018 were reviewed prospectively, with the collection of demographic and psychosocial data, preoperative CT, and complications during follow-up of two years. The primary outcome measure was the Western Ontario Shoulder Instability Index (WOSI), assessed preoperatively, at two years postoperatively, and at mid-term follow-up at a mean of 50.6 months (SD 24.8) postoperatively. The secondary outcome measure was the abbreviated version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) score. The influence of the demographic details of the patients, measurements of the severity of instability, and the complications of surgery were assessed in a multivariate analysis.Aims
Methods
Improvements in the evaluation of outcomes following peripheral nerve injury are needed. Recent studies have identified muscle fatigue as an inevitable consequence of muscle reinnervation. This study aimed to quantify and characterize muscle fatigue within a standardized surgical model of muscle reinnervation. This retrospective cohort study included 12 patients who underwent Oberlin nerve transfer in an attempt to restore flexion of the elbow following brachial plexus injury. There were ten men and two women with a mean age of 45.5 years (27 to 69). The mean follow-up was 58 months (28 to 100). Repeated and sustained isometric contractions of the elbow flexors were used to assess fatigability of reinnervated muscle. The strength of elbow flexion was measured using a static dynamometer (KgF) and surface electromyography (sEMG). Recordings were used to quantify and characterize fatigability of the reinnervated elbow flexor muscles compared with the uninjured contralateral side.Aims
Patients and Methods
The crucial role of the radial head in the stability of the elbow in terrible triad injury is acknowledged. This retrospective study aims to compare the results of resection of a severely comminuted radial head with or without prosthetic arthroplasty as part of the reconstruction for this injury. The outcome of radial head resection was compared with prosthetic arthroplasty in 29 and 15 patients with terrible triad injuries, respectively. There were ten female patients (34.5%) in the resection group and six female patients (40%) in the prosthesis group. The mean age was 40.7 years (Aims
Patients and Methods
The aim of the study was to analyze the results of primary tendon
reinsertion in acute and chronic distal triceps tendon ruptures
(DTTRs) in the general population. A total of 28 patients were operated on for primary DTTR reinsertions,
including 21 male patients and seven female patients with a mean
age of 45 years (14 to 76). Of these patients, 23 sustained an acute
DTTR and five had a chronic injury. One patient had a non-simultaneous
bilateral DTTR. Seven patients had DTTR-associated ipsilateral fracture
or dislocation. Comorbidities were present in four patients. Surgical
treatment included transosseous and suture-anchors reinsertion in
22 and seven DTTRs, respectively. The clinical evaluation was performed
using Mayo Elbow Performance Score (MEPS), the modified American
Shoulder and Elbow Surgeons Score (m-ASES), the Quick Disabilities
of the Arm, Shoulder and Hand score (QuickDASH), and the Medical
Research Council (MRC) Scale.Aims
Patients and Methods
The aim of this study was to evaluate two hypotheses. First,
that disruption of posterior bundle of the medial collateral ligament
(PMCL) has to occur for the elbow to subluxate in cases of posteromedial
rotatory instability (PMRI) and second, that ulnohumeral contact
pressures increase after disruption of the PMCL. Six human cadaveric elbows were prepared on a custom-designed
apparatus which allowed muscle loading and passive elbow motion
under gravitational varus. Joint contact pressures were measured
sequentially in the intact elbow (INTACT), followed by an anteromedial
subtype two coronoid fracture (COR), a lateral collateral ligament (LCL)
tear (COR + LCL), and a PMCL tear (COR + LCL + PMCL).Aims
Materials and Methods
The aim of this retrospective multicentre study was to evaluate
mid-term results of the operative treatment of Monteggia-like lesions
and to determine the prognostic factors that influence the clinical
and radiological outcome. A total of 46 patients (27 women and 19 men), with a mean age
of 57.7 years (18 to 84) who had sustained a Monteggia-like lesion
were followed up clinically and radiologically after surgical treatment.
The Mayo Modified Wrist Score (MMWS), Mayo Elbow Performance Score
(MEPS), Broberg and Morrey Score, and Disabilities of the Arm, Shoulder
and Hand (DASH) score were used for evaluation at a mean of 65 months
(27 to 111) postoperatively. All ulnar fractures were stabilized
using a proximally contoured or precontoured locking compression
plate. Mason type I fractures of the radial head were treated conservatively, type
II fractures were treated with reconstruction, and type III fractures
with arthroplasty. All Morrey type II and III fractures of the coronoid
process was stabilized using lag screws.Aims
Patients and Methods
Medium-term results of the Discovery elbow replacement
are presented. We reviewed 51 consecutive primary Discovery total
elbow replacements (TERs) implanted in 48 patients. The mean age
of the patients was 69.2 years (49 to 92), there were 19 males and
32 females (37%:63%) The mean follow-up was 40.6 months (24 to 69).
A total of six patients were lost to follow-up. Statistically significant
improvements in range movement and Oxford Elbow Score were found
(p <
0.001). Radiolucent lines were much more common in, and
aseptic loosening was exclusive to, the humeral component. Kaplan–Meier
survivorship at five years was 92.2% (95% CI 74.5% to 96.4%) for
aseptic loosening. In four TERs, periprosthetic infection occurred
resulting in failure. A statistically significant association between
infection and increased BMI was found (p = 0.0268). Triceps failure
was more frequent after the Mayo surgical approach and TER performed
after previous trauma surgery. No failures of the implant were noted. Our comparison shows that the Discovery has early clinical results
that are similar to other semi-constrained TERs. We found continued
radiological surveillance with particular focus on humeral lucency
is warranted and has not previously been reported. Despite advances
in the design of total elbow replacement prostheses, rates of complication
remain high. Cite this article:
Treatment of an infected total elbow replacement
(TER) is often successful in eradicating or suppressing the infection.
However, the extensor mechanism may be compromised by both the infection
and the surgery. The goal of this study was to assess triceps function
in patients treated for deep infection complicating a TER. Between
1976 and 2007 a total of 217 TERs in 207 patients were treated for
infection of a TER at our institution. Superficial infections and
those that underwent resection arthroplasty were excluded, leaving
93 TERs. Triceps function was assessed by examination and a questionnaire.
Outcome was measured using the Mayo Elbow Performance Score (MEPS). Triceps weakness was identified in 51 TERs (49 patients, 55%).
At a mean follow-up of five years (0.8 to 34), the extensor mechanism
was intact in 13 patients, with the remaining 38 having bone or
soft-tissue loss. The mean MEPS was 70 points (5 to 100), with a
mean functional score of 18 (0 to 25) of a possible 25 points. Infection following TER can often be eradicated; however, triceps
weakness occurs in more than half of the patients and may represent
a major functional problem. Cite this article:
Between 2002 and 2011, 81 patients with a traumatic total brachial
plexus injury underwent reconstruction by double free muscle transfer
(DFMT, 47 cases), single muscle transfer (SMT, 16 cases) or nerve
transfers (NT, 18 cases). They were evaluated for functional outcome and quality of life
(QoL) using the Disability of Arm, Shoulder and Hand questionnaire,
both pre- and post-operatively. The three groups were compared and
followed-up for at least 24 months.Aims
Methods
To prevent insufficiency of the triceps after
total elbow arthroplasty, we have, since 2008, used a triceps-sparing ulnar
approach. This study evaluates the clinical results and post-operative
alignment of the prosthesis using this approach. We reviewed 25 elbows in 23 patients. There were five men and
18 women with a mean age of 69 years (54 to 83). There were 18 elbows
with rheumatoid arthritis, six with a fracture or pseudoarthrosis
and one elbow with osteoarthritis. Post-operative complications included one intra-operative fracture,
one elbow with heterotopic ossification, one transient ulnar nerve
palsy, and one elbow with skin necrosis, but no elbow was affected
by insufficiency of the triceps. Patients were followed for a mean of 42 months (24 to 77). The
mean post-operative Japanese Orthopaedic Association Elbow Score
was 90.8 (51 to 100) and the mean Mayo Elbow Performance score 93.8
(65 to 100). The mean post-operative flexion/extension of the elbow
was 135°/-8°. The Manual Muscle Testing score of the triceps was
5 in 23 elbows and 2 in two elbows (one patient). The mean alignment
of the implants examined by 3D-CT was 2.8° pronation (standard deviation
( The triceps-sparing ulnar approach allows satisfactory alignment
of the implants, is effective in preventing post-operative triceps
insufficiency, and gives satisfactory short-term results. Cite this article: 2015;97-B:1096–1101.
The natural history of primary anterior dislocation
of the glenohumeral joint in adolescent patients remains unclear and
there is no consensus for management of these patients. The objectives of this study were to report the natural history
of primary anterior dislocation of the glenohumeral joint in adolescent
patients and to identify the risk factors for recurrent dislocation. We reviewed prospectively-collected clinical and radiological
data on 133 adolescent patients diagnosed with a primary anterior
dislocation of the glenohumeral joint who had been managed non-operatively
at our hospital between 1996 and 2008. There were 115 male (86.5%)
and 18 female patients (13.5%) with a mean age of 16.3 years (13
to 18) and a mean follow-up of 95.2 months (1 to 215). During follow-up, 102 (absolute incidence of 76.7%) patients
had a recurrent dislocation. The median interval between primary
and recurrent dislocation was ten months (95% CI 7.4 to 12.6). Applying
survival analysis the likelihood of having a stable shoulder one
year after the initial injury was 59% (95% CI 51.2 to 66.8), 38%
(95% CI 30.2 to 45.8%) after two years, 21% (95% CI 13.2 to 28.8)
after five years, and 7% (95% CI 1.1 to 12.9) after ten years. Neither
age nor gender significantly predicted recurrent dislocation during
follow-up. We conclude that adolescent patients with a primary anterior
dislocation of the glenohumeral joint have a high rate of recurrent
dislocation, which usually occurs within two years of their initial
injury: these patients should be considered for early operative
stabilisation. Cite this article:
In this study we evaluated whether the Instability
Severity Index Score (ISIS) and the Western Ontario Shoulder Instability
Index (WOSI) could detect those patients at risk of failure following
arthroscopic Bankart repair. Between April 2008 and June 2010, the
ISIS and WOSI were recorded pre-operatively in 110 patients (87
male, 79%) with a mean age of 25.1 years (16 to 61) who underwent
this procedure for recurrent anterior glenohumeral instability. A telephone interview was performed two-years post-operatively
to determine whether patients had experienced a recurrent dislocation
and whether they had returned to pre-injury activity levels. In
all, six (5%) patients had an ISIS >
6 points (0 to 9). Of 100 (91%)
patients available two years post-operatively, six (6%) had a recurrent dislocation,
and 28 (28%) did not return to pre-injury activity. No patient who
dislocated had an ISIS >
6 (p = 1.0). There was no difference in
the mean pre-operative WOSI in those who had a re-dislocation and
those who did not (p = 0.99). The pre-operative WOSI was significantly
lower (p = 0.02) in those who did not return to pre-injury activity, whereas
the ISIS was not associated with return to pre-injury activity (p
= 0.13). In conclusion, neither the pre-operative ISIS nor WOSI predicted
recurrent dislocation within two years of arthroscopic Bankart repair.
Patients with a lower pre-operative WOSI were less likely to return
to pre-injury activity. 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:
