Damage to the cartilage of the distal radioulnar
joint frequently leads to pain and limitation of movement, therefore repair
of this joint cartilage would be highly desirable. The purpose of
this study was to investigate the fixation of scaffold in cartilage
defects of this joint as part of matrix-assisted regenerative autologous
cartilage techniques. Two techniques of fixation of collagen scaffolds,
one involving fibrin glue alone and one with fibrin glue and sutures, were
compared in artificially created cartilage defects of the distal
radioulnar joint in a human
Aims. There is ambiguity surrounding the degree of scaphoid union required to safely allow mobilization following scaphoid waist fracture. Premature mobilization could lead to refracture, but late mobilization may cause stiffness and delay return to normal function. This study aims to explore the risk of refracture at different stages of scaphoid waist fracture union in three common fracture patterns, using a novel finite element method. Methods. The most common anatomical variant of the scaphoid was modelled from a CT scan of a healthy hand and wrist using 3D Slicer freeware. This model was uploaded into COMSOL Multiphysics software to enable the application of physiological enhancements. Three common waist fracture patterns were produced following the Russe classification. Each fracture had differing stages of healing, ranging from 10% to 90% partial union, with increments of 10% union assessed. A physiological force of 100 N acting on the distal pole was applied, with the risk of refracture assessed using the Von Mises stress. Results. Overall, 90% to 30% fracture unions demonstrated a small, gradual increase in the Von Mises stress of all fracture patterns (16.0 MPa to 240.5 MPa). All fracture patterns showed a greater increase in Von Mises stress from 30% to 10% partial union (680.8 MPa to 6,288.6 MPa). Conclusion. Previous studies have suggested 25%, 50%, and 75% partial union as sufficient for resuming hand and wrist mobilization. This study shows that 30% union is sufficient to return to normal hand and wrist function in all three fracture patterns. Both 50% and 75% union are unnecessary and increase the risk of post-fracture stiffness. This study has also demonstrated the feasibility of finite element analysis (FEA) in scaphoid waist fracture research. FEA is a sustainable method which does not require the use of finite scaphoid
Patients with midcarpal instability are difficult to manage. It is a rare condition, and few studies have reported the outcomes of surgical treatment. No prospective or retrospective study has reported the results of arthroscopic palmar capsuloligamentous suturing. Our aim was to report the results of a prospective study of arthroscopic suture of this ligament complex in patients with midcarpal instability. This prospective single-centre study was undertaken between March 2012 and May 2022. The primary outcome was to evaluate the functional outcomes of arthroscopic palmar midcarpal suture. The study included 12 patients, eight male and four female, with a mean age of 27.5 years (19 to 42). They were reviewed at three months, six months, and one year postoperatively.Aims

We conducted an anatomical study to determine
the best technique for transfer of the anterior interosseous nerve (AIN)
for the treatment of proximal ulnar nerve injuries. The AIN, ulnar
nerve, and associated branches were dissected in 24
Penetration of the dorsal screw when treating
distal radius fractures with volar locking plates is an avoidable complication
that causes lesions of the extensor tendon in between 2% and 6%
of patients. We examined axial fluoroscopic views of the distal
end of the radius to observe small amounts of dorsal screw penetration,
and determined the ideal angle of inclination of the x-ray beam
to the forearm when making this radiological view. Six volar locking plates were inserted at the wrists of
The objective of this systematic review was to describe trapeziectomy outcomes and complications in the context of osteoarthritis of the base of the thumb after a five-year minimum follow-up. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to guide study design, and 267 full-text articles were assessed for eligibility. After exclusion criteria application, 22 studies were included, involving 728 patients and 823 trapeziectomies. Outcomes included pre- and postoperative clinical and radiological characteristics. Complications and revisions were recorded.Aims
Methods
The aim of this study was to analyze the association between the shape of the distal radius sigmoid notch and triangular fibrocartilage complex (TFCC) foveal tear. Between 2013 and 2018, patients were retrospectively recruited in two different groups. The patient group comprised individuals who underwent arthroscopic transosseous TFCC foveal repair for foveal tear of the wrist. The control group comprised individuals presenting with various diseases around wrist not affecting the TFCC. The study recruited 176 patients (58 patients, 118 controls). The sigmoid notch shape was classified into four types (flat-face, C-, S-, and ski-slope types) and three radiological parameters related to the sigmoid notch (namely, the radius curvature, depth, and version angle) were measured. The association of radiological parameters and sigmoid notch types with the TFCC foveal tear was investigated in univariate and multivariate analyses. Receiver operating characteristic curves were used to estimate a cut-off for any statistically significant variables.Aims
Methods
The aim of this study was to investigate whether intraoperative 3D fluoroscopic imaging outperforms dorsal tangential views in the detection of dorsal cortex screw penetration after volar plating of an intra-articular distal radial fracture, as identified on postoperative CT imaging. A total of 165 prospectively enrolled patients who underwent volar plating for an intra-articular distal radial fracture were retrospectively evaluated to study three intraoperative imaging protocols: 1) standard 2D fluoroscopic imaging with anteroposterior (AP) and elevated lateral images (n = 55); 2) 2D fluoroscopic imaging with AP, lateral, and dorsal tangential views images (n = 50); and 3) 3D fluoroscopy (n = 60). Multiplanar reconstructions of postoperative CT scans served as the reference standard.Aims
Methods
Positive ulnar variance is an established risk factor for idiopathic
ulnar impaction syndrome (UIS). However, not all patients with positive
ulnar variance develop symptomatic UIS and other factors, including
the morphology of the lunate, may be involved. The aim of this study
was to clarify the relationship between lunate morphology and idiopathic
UIS. A cohort of 95 patients with idiopathic UIS (UIS group) was compared
with 95 asymptomatic controls with positive ulnar variance. The
shape of the lunate was measured using the capitate-triquetrum distance
(CTD), ulnar coverage ratio (UCR), radiolunate distance and radiolunate
angle. The association of radiographic parameters and lunate types
with the development of UIS was investigated in univariable and
multivariable analyses. Receiver operating characteristic curves
were used to estimate a cutoff for any statistically significant
variables.Aims
Patients and Methods
The aims of this study were: firstly, to investigate the influence
of the thickness of cartilage at the sigmoid notch on the inclination
of the distal radioulnar joint (DRUJ), and secondly, to compare
the sensitivity and specificity of MRI with plain radiographs for
the assessment of the inclination of the articular surface of the
DRUJ in the coronal plane. Contemporaneous MRI images and radiographs of 100 wrists from
98 asymptomatic patients (mean age 43 years, (16 to 67); 52 male,
53%) with no history of a fracture involving the wrist or surgery
to the wrist, were reviewed. The thickness of the cartilage at the
sigmoid notch, inclination of the DRUJ and Tolat Type of each DRUJ
were determined. Aims
Patients and Methods
The aims of this study were to compare the mid-term outcomes
of patients with late-stage arthritis of the wrist treated with
proximal row carpectomy (PRC) and dorsal capsular interposition
(DCI) arthroplasty with a matched cohort treated with routine PRC
alone. A total of 25 arthritic wrists (24 patients) with pre-existing
degenerative changes of the proximal capitate and/or the lunate
fossa of the radius were treated with PRC + DCI over a ten-year
period. This group of patients were matched 1:2 with a group of
50 wrists (48 patients) without degenerative changes in the capitate
or lunate fossa that were treated with a routine PRC alone during
the same period. The mean age of the patients at the time of surgery
was 56.8 years (25 to 81), and the demographics and baseline range
of movement of the wrist, grip strength, Quick Disabilities of the
Arm, Shoulder, and Hand (QuickDASH) score, and Patient-Rated Wrist
Evaluation (PRWE) score were similar in both groups. Aims
Patients and Methods
The degree of displacement of a fracture of the distal radius
is an important factor which can be assessed using simple radiographic
measurements. Our aim was to investigate the reliability and reproducibility
of these measurements and to determine if they should be used clinically. A 10% sample was randomly generated from 3670 consecutive adult
patients who had presented to University Hospitals of Leicester
NHS Trust between 2007 and 2010 with a fracture of the distal radius.
Radiographs of the 367 patients were assessed by two independent
reviewers. Four measurements of displacement of the fracture were recorded
and the inter-observer correlation assessed using the intra-class
correlation coefficient.Aims

We report a new surgical technique of open carpal
tunnel release with subneural reconstruction of the transverse carpal
ligament and compare this with isolated open and endoscopic carpal
tunnel release. Between December 2007 and October 2011, 213 patients with carpal
tunnel syndrome (70 male, 143 female; mean age 45.6 years; 29 to
67) were recruited from three different centres and were randomly
allocated to three groups: group A, open carpal tunnel release with
subneural reconstruction of the transverse carpal ligament (n =
68); group B, isolated open carpal tunnel release (n = 92); and
group C, endoscopic carpal tunnel release (n = 53). At a mean final follow-up of 24 months (22 to 26), we found no
significant difference between the groups in terms of severity of
symptoms or lateral grip strength. Compared with groups B and C,
group A had significantly better functional status, cylindrical
grip strength and pinch grip strength. There were significant differences
in Michigan Hand Outcome scores between groups A and B, A and C,
and B and C. Group A had the best functional status, cylindrical
grip strength, pinch grip strength and Michigan Hand Outcome score. Subneural reconstruction of the transverse carpal ligament during
carpal tunnel decompression maximises hand strength by stabilising
the transverse carpal arch. Cite this article:
We report a new surgical technique for the treatment
of traumatic dislocation of the carpometacarpal (CMC) joint of the
thumb. This is a tenodesis which uses part of the flexor carpi radialis. Between January 2010 and August 2013, 13 patients with traumatic
instability of the CMC joint of the thumb were treated using this
technique. The mean time interval between injury and ligament reconstruction
was 13 days (0 to 42). The mean age of the patients at surgery was
38 years: all were male. At a mean final follow-up of 26 months (24 to 29), no patient
experienced any residual instability. The mean total palmar abduction
of the CMC joint of the thumb was 61° and the mean radial abduction
65° The mean measurements for the uninjured hand were 66° (60° to
73°) and 68° (60° to 75°), respectively. The mean Kapandji thumb
opposition score was 8.5° (8° to 9°). The mean pinch and grip strengths
of the hand were 6.7 kg (3.4 to 8.2) and 40 kg (25 to 49), respectively.
The mean Disabilities of the Arm, Shoulder, and Hand questionnaire
score was 3 (1 to 6). Based on the Smith and Cooney score, we obtained
a mean score of 85 (75 to 95), which included four excellent, seven
good, and two fair results. Our technique offers an alternative method of treating traumatic
dislocation of the CMC joint of the thumb: it produces a stable
joint and acceptable hand function. Cite this article:
Arthritis of the wrist is a painful disabling
condition that has various causes and presentations. The traditional treatment
has been a total wrist fusion at a price of the elimination of movement.
However, forms of treatment which allow the preservation of movement
are now preferred. Modern arthroplasties of the wrist are still
not sufficiently robust to meet the demands of many patients, nor
do they restore normal kinematics of the wrist. A preferable compromise
may be selective excision and partial fusion of the wrist using
knowledge of the aetiology and pattern of degenerative change to
identify which joints can be sacrificed and which can be preserved. This article provides an overview of the treatment options available
for patients with arthritis of the wrist and an algorithm for selecting
an appropriate surgical strategy. Cite this article:
The osteoinductive properties of demineralised
bone matrix have been demonstrated in animal studies. However, its therapeutic
efficacy has yet to be proven in humans. The clinical properties
of AlloMatrix, an injectable calcium-based demineralised bone matrix
allograft, were studied in a prospective randomised study of 50
patients with an isolated unstable distal radial fracture treated
by reduction and Kirschner (K-) wire fixation. A total of 24 patients
were randomised to the graft group (13 men and 11 women, mean age
42.3 years (20 to 62)) and 26 to the no graft group (8 men and 18
women, mean age 45.0 years (17 to 69)). At one, three, six and nine weeks, and six and 12 months post-operatively,
patients underwent radiological evaluation, assessments for range
of movement, grip and pinch strength, and also completed the Disabilities
of Arm, Shoulder and Hand questionnaire. At one and six weeks and
one year post-operatively, bone mineral density evaluations of both
wrists were performed. No significant difference in wrist function and speed of recovery,
rate of union, complications or bone mineral density was found between
the two groups. The operating time was significantly higher in the
graft group (p = 0.004). Radiologically, the reduction parameters
remained similar in the two groups and all AlloMatrix extraosseous leakages
disappeared after nine weeks. This prospective randomised controlled trial did not demonstrate
a beneficial effect of AlloMatrix demineralised bone matrix in the
treatment of this category of distal radial fractures treated by
K-wire fixation. Cite this article:
