Determining and accurately restoring the flexion-extension
axis of the elbow is essential for functional recovery after total
elbow arthroplasty (TEA). We evaluated the effect of morphological
features of the elbow on variations of alignment of the components
at TEA. Morphological and positioning variables were compared by
systematic CT scans of 22 elbows in 21 patients after TEA. There were five men and 16 women, and the mean age was 63 years
(38 to 80). The mean follow-up was 22 months (11 to 44). The anterior offset and version of the humeral components were
significantly affected by the anterior angulation of the humerus
(p = 0.052 and p = 0.004, respectively). The anterior offset and
version of the ulnar components were strongly significantly affected
by the anterior angulation of the ulna (p <
0.001 and p <
0.001). The closer the anterior angulation of the ulna was to the joint,
the lower the ulnar anterior offset (p = 0.030) and version of the
ulnar component (p = 0.010). The distance from the joint to the
varus angulation also affected the lateral offset of the ulnar component
(p = 0.046). Anatomical variations at the distal humerus and proximal ulna
affect the alignment of the components at TEA. This is explained
by abutment of the stems of the components and is particularly severe
when there are substantial deformities or the deformities are close
to the joint. Cite this article:
The aim of this study was to analyze how proximal radial neck resorption (PRNR) starts and progresses radiologically in two types of press-fit radial head arthroplasties (RHAs), and to investigate its clinical relevance. A total of 97 patients with RHA were analyzed: 56 received a bipolar RHA (Group 1) while 41 received an anatomical implant (Group 2). Radiographs were performed postoperatively and after three, six, nine, and 12 weeks, six, nine, 12, 18, and 24 months, and annually thereafter. PRNR was measured in all radiographs in the four radial neck quadrants. The Mayo Elbow Performance Score (MEPS), the abbreviated version of the Disabilities of the Arm, Shoulder, and Hand questionnaire (QuickDASH), and the patient-assessed American Shoulder and Elbow Surgeons score - Elbow (pASES-E) were used for the clinical assessment. Radiological signs of implant loosening were investigated.Aims
Methods
Arthroplasties of the elbow, including total elbow arthroplasty, radial head arthroplasty, distal humeral hemiarthroplasty, and radiocapitellar arthroplasty, are rarely undertaken. This scoping review aims to outline the current research in this area to inform the development of future research. A scoping review was undertaken adhering to the Joanna Briggs Institute guidelines using Medline, Embase, CENTRAL, and trial registries, limited to studies published between 1 January 1990 and 7 February 2021. Endnote software was used for screening and selection, and included randomized trials, non-randomized controlled trials, prospective and retrospective cohort studies, case-control studies, analytical cross-sectional studies, and case series of ten or more patients reporting the clinical outcomes of elbow arthroplasty. The results are presented as the number of types of studies, sample size, length of follow-up, clinical outcome domains and instruments used, sources of funding, and a narrative review.Aims
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
The aim of this study was to evaluate the outcome of Monteggia-like lesions at midterm follow-up and to determine whether the surgical treatment of the radial head influences the clinical and radiological results. A total of 78 patients with a Monteggia-like lesion, including 44 women and 34 men with a mean age of 54.7 years (19 to 80), were available for assessment after a mean 4.6 years (2 to 9.2). The outcome was assessed using the Mayo Elbow Performance Score (MEPS), Oxford Elbow Score (OES), Mayo Modified Wrist Score (MMWS), and The Disabilities of the Arm, Shoulder and Hand (DASH) score. Radiographs were analyzed for all patients. A total of 12 Mason type I, 16 type II, and 36 type III fractures were included. Surgical treatment consisted of screw fixation for all type II and reconstructable type III fractures, while radial head arthroplasty (RHA) or excision was performed if reconstruction was not possible.Aims
Patients and 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 primary aim of this retrospective study was to identify the
incidence of heterotopic ossification (HO) following elective and
trauma elbow arthroplasty. The secondary aim was to determine clinical
outcomes with respect to the formation of heterotopic ossification. A total of 55 total elbow arthroplasties (TEAs) (52 patients)
performed between June 2007 and December 2015 were eligible for
inclusion in the study (29 TEAs for primary elective arthroplasty
and 26 TEAs for trauma). At review, 15 patients (17 total elbow
arthroplasties) had died from unrelated causes. There were 14 men
and 38 women with a mean age of 70 years (42 to 90). The median
clinical follow-up was 3.6 years (1.2 to 6) and the median radiological follow-up
was 3.1 years (0.5 to 7.5).Aim
Patients and Methods
We report our experience of performing an elbow
hemiarthroplasty in the treatment of comminuted distal humeral fractures
in the elderly patients. A cohort of 42 patients (three men and 39 women, mean age 72;
56 to 84) were reviewed at a mean of 34.3 months (24 to 61) after
surgery. Functional outcome was measured with the Mayo Elbow Performance
Score (MEPS) and range of movement. The disabilities of the arm,
shoulder and hand questionnaire (DASH) was used as a patient rated
evaluation. Complications and ulnar nerve function were recorded.
Plain radiographs were obtained to assess prosthetic loosening,
olecranon wear and heterotopic bone formation. The mean extension deficit was 23.5° (0° to 60°) and mean flexion
was 126.8° (90° to 145°) giving a mean arc of 105.5° (60° to 145°).
The mean MEPS was 90 (50 to 100) and a mean DASH score of 20 (0
to 63). Four patients had additional surgery for limited range of
movement and one for partial instability. One elbow was revised
due to loosening, two patients had sensory ulnar nerve symptoms,
and radiographic signs of mild olecranon wear was noted in five
patients. Elbow hemiarthroplasty for comminuted intra-articular distal
humeral fractures produces reliable medium-term results with functional
outcome and complication rates, comparable with open reduction and
internal fixation and total elbow arthroplasty. Cite this article:
We assessed the long-term (more than ten-year) outcomes of the
Kudo type-5 elbow prosthesis in patients with rheumatoid arthritis
(RA). We reviewed 41 elbows (Larsen Grade IV, n = 21; Grade V, n =
20) in 31 patients with RA who had undergone a Kudo type-5 total
elbow arthroplasty (TEA) between 1994 and 2003, and had been followed
up for more than ten years. The humeral component was cementless
and the all-polyethylene ulnar component cemented in every patient. Clinical
outcome was assessed using the Mayo elbow performance score. We
calculated the revision rate and evaluated potential risk factors
for revision. The duration of follow-up was a mean 141 months (120
to 203).Aims
