This study aimed to assess the impact of using the metal-augmented glenoid baseplate (AGB) on improving clinical and radiological outcomes, as well as reducing complications, in patients with superior glenoid wear undergoing reverse shoulder arthroplasty (RSA). From January 2016 to June 2021, out of 235 patients who underwent primary RSA, 24 received a superior-AGB after off-axis reaming (Group A). Subsequently, we conducted propensity score matching in a 1:3 ratio, considering sex, age, follow-up duration, and glenoid wear (superior-inclination and retroversion), and selected 72 well-balanced matched patients who received a standard glenoid baseplate (STB) after eccentric reaming (Group B). Superior-inclination, retroversion, and lateral humeral offset (LHO) were measured to assess preoperative glenoid wear and postoperative correction, as well as to identify any complications. Clinical outcomes were measured at each outpatient visit before and after surgery.Aims
Methods
The aim of this study was to compare the clinical and radiological outcomes of reverse shoulder arthroplasty (RSA) using small and standard baseplates in Asian patients, and to investigate the impact of a mismatch in the sizes of the glenoid and the baseplate on the outcomes. This was retrospective analysis of 50 and 33 RSAs using a standard (33.8 mm, ST group) and a small (29.5 mm, SM group) baseplate of the Equinoxe reverse shoulder system, which were undertaken between January 2017 and March 2021. Radiological evaluations included the size of the glenoid, the Aims

Non-tuberculous mycobacterial (NTM) infection
of the musculoskeletal tissue is a rare disease. An early and accurate diagnosis
is often difficult because of the indolent clinical course and difficulty
of isolating pathogens. Our goal was to determine the clinical features
of musculoskeletal NTM infection and to present the treatment outcomes.
A total of 29 patients (nine females, 20 males between 34 and 85
years old, mean age 61.7 years; 34 to 85) with NTM infection of the
musculoskeletal system between 1998 to 2011 were identified and
their treatment retrospectively analysed. Microbiological studies
demonstrated NTM in 29 patients: the isolates were Cite this article:
This study was performed to determine whether
pure cancellous bone graft and Kirschner (K-) wire fixation were sufficient
to achieve bony union and restore alignment in scaphoid nonunion.
A total of 65 patients who underwent cancellous bone graft and K-wire
fixation were included in this study. The series included 61 men
and four women with a mean age of 34 years (15 to 72) and mean delay
to surgery of 28.7 months (3 to 240). The patients were divided
into an unstable group (A) and stable group (B) depending on the
pre-operative radiographs. Unstable nonunion was defined as a lateral
intrascaphoid angle >
45°, or a radiolunate angle >
10°. There were
34 cases in group A and 31 cases in group B. Bony union was achieved
in 30 patients (88.2%) in group A, and in 26 (83.9%) in group B
(p = 0.439). Comparison of the post-operative radiographs between
the two groups showed no significant differences in lateral intrascaphoid
angle (p = 0.657) and scaphoid length
(p = 0.670) and height (p = 0.193). The radiolunate angle was significantly
different
(p = 0.020) but the mean value in both groups was <
10°. Comparison
of the dorsiflexion and palmar flexion of movement of the wrist
and the mean Mayo wrist score at the final clinical visit in each
group showed no significant difference (p = 0.190, p = 0.587 and
p = 0.265, respectively). Cancellous bone graft and K-wire fixation
were effective in the treatment of stable and unstable scaphoid
nonunion. Cite this article:
We reviewed the outcome of distal chevron metatarsal osteotomy without tendon transfer in 19 consecutive patients (19 feet) with a hallux varus deformity following surgery for hallux valgus. All patients underwent distal chevron metatarsal osteotomy with medial displacement and a medial closing wedge osteotomy along with a medial capsular release. The mean hallux valgus angle improved from −11.6° pre-operatively to 4.7° postoperatively, the mean first-second intermetatarsal angle improved from −0.3° to 3.3° and the distal metatarsal articular angle from 9.5° to 2.3° and the first metatarsophalangeal joints became congruent post-operatively in all 19 feet. The mean relative length ratio of the metatarsus decreased from 1.01 to 0.99 and the mean American Orthopaedic Foot and Ankle Society score improved from 77 to 95 points. In two patients the hallux varus recurred. One was symptom-free but the other remained symptomatic after a repeat distal chevron osteotomy. There were no other complications. We consider that distal chevron metatarsal osteotomy with a medial wedge osteotomy and medial capsular release is a useful procedure for the correction of hallux varus after surgery for hallux valgus.
We reviewed the results of a selective à la carte soft-tissue release operation for recurrent or residual deformity after initial conservative treatment for idiopathic clubfoot by the Ponseti method. Recurrent or residual deformity occurred in 13 (19 feet) of 33 patients (48 feet; 40%). The mean age at surgery was 2.3 years (1.3 to 4) and the mean follow-up was 3.6 years (2 to 5.3). The mean Pirani score had improved from 2.8 to 1.1 points, and the clinical and radiological results were satisfactory in all patients. However, six of the 13 patients (9 of 19 feet) had required further surgery in the form of tibial derotation osteotomy, split anterior tibialis tendon transfer, split posterior tibialis transfer or a combination of these for recurrent deformity. We concluded that selective soft-tissue release can provide satisfactory early results after failure of initial treatment of clubfoot by the Ponseti method, but long-term follow-up to skeletal maturity will be necessary.
We studied 11 patients with checkrein deformities of the hallux who underwent surgical treatment. Six had lengthening of the flexor hallucis longus tendon by Z-plasty in the midfoot, and five underwent release of adhesions and lengthening of the tendon by Z-plasty at the musculotendinous junction at the fracture site. All six patients who underwent Z-plasty at the midfoot showed complete correction of the deformity without recurrence. Of the five who had release of adhesions and Z-plasty of the tendon at the fracture site, two showed partial and one showed complete recurrence.
We performed nine metatarsal and three proximal phalangeal lengthenings in five patients with congenital brachymetatarsia of the first and one or two other metatarsal bones, by a one-stage combined shortening and lengthening procedure using intercalcary autogenous bone grafts from adjacent shortened metatarsal bones. Instead of the isolated lengthening of the first and the other metatarsal bones, we shortened the adjacent normal metatarsal and used the excised bone to lengthen the short toes, except for the great toe, to restore the normal parabola. One skin incision was used. All the operations were performed bilaterally and the patients were followed up for a mean period of 69.5 months (29 to 107). They all regained a nearly normal parabola and were satisfied with the cosmetic results. Our technique is straightforward and produces good cosmetic results. Satisfactory, bony union is achieved, morbidity is low, and no additional surgery is required for the removal of metal implants.
