ABSTRACT
The management of isolated radial neck and head fractures is controversial. Plate fixation and tripod fixation are two commonly employed techniques but risk damage to soft tissues and implant-related complications. Intramedullary fixation is commonly used in pediatric cases and reduces the potential drawbacks of open fixation. This systematic review aimed to analyze outcomes of intramedullary fixation in adults in terms of function, union, and complication rates. A systematic review of the literature was conducted following the PRISMA guidelines using Medline and EMBASE's online databases. The review was registered on the PROSPERO database. Studies were appraised using the Methodological Index for non-randomized studies (MINORS) tool. Seven studies were deemed eligible for inclusion (n=55). Mean ages of patients ranged from 31.3 to 44.2 years, and mean follow-up ranged from 9 to 86 months. The Mayo Elbow Performance score (MEPs) was reported in five case series (mean scores 81.8 -97.9) and the prevalence of excellent results ranged from 71% and 83%. Although 100% of fractures united, the pooled complication rate was 24% (range 0-50%). The most common complications were elbow stiffness (7%), superficial radial nerve neuropraxia (7%), malunion (5%), and AVN (1.8%). No study reported any patients requiring revision surgery. Intramedullary fixation for radial head and neck fractures appears to provide a reliable alternative treatment option in terms of union, range of motion, and functional outcomes. Further robust trials direct comparing against open fixation techniques are required.

BACKGROUND: Acetabular bone loss is a challenging problem for revision hip surgeons. This study aimed to explore long-term outcomes of patients who have undergone cemented acetabular revision in conjunction with trabecular metal augmentation and impaction bone grafting in cases with significant segmental bone loss. METHODS: All patients who underwent cemented acetabular revision requiring impaction bone grafting and trabecular metal augments with a minimum Paprosky score of 2B and minimum follow up of 5 years were identified. Pre- and postoperative WOMAC scores were compared. An assessment of pre- and postoperative hip centre of rotation was performed and compared to native centre of rotation. Immediate postoperative centre of rotation was then compared to radiographs at latest follow up to measure for migration of acetabular components. RESULTS: 42 patients were identified. Mean age was 53 years old with 7 males and 35 female patients. Mean follow-up was 9.5 years. Preoperative WOMAC score was 30 and there was an increase to 90 (p < 0.01) at latest follow-up. No hips were revised for loosening or infection. There was a mean improvement in centre of rotation of 6.80 mm (CI, 4.57-9.03 mm) which was significant (p < 0.00002). There was no change of position of centre of rotation from immediate postoperative radiographs and those at latest follow up (p = 0.3). CONCLUSIONS: Cemented acetabular components work well in conjunction with trabecular metal augments and impacted bone grafts in reconstructing complex acetabular defects. Together they provide immediate and long-term component stability, with excellent long-term clinical and radiological outcomes.

The management of elbow fracture-dislocations is challenging. The internal joint stabiliser (IJS) (Skeletal Dynamics, Miami, FL) has been advocated as an alternative to traditional techniques. This article shares our initial clinical experience and provide a systematic review analysing the ability of the IJS to maintain radiographic joint reduction and the associated complication profile. Two cases of elbow fracture-dislocations treated at our centre using the IJS are presented. A systematic review of the literature was conducted using the online databases Medline, Scopus and EMBASE. Clinical studies reporting the maintenance of joint reduction after the use of IJS in patients with acute or chronic elbow instability were included. The two cases reported remained radiographically concentric at 6 months follow up without complications. 5 studies met the inclusion criteria and were included in the systematic review (total n=65). Only two patients across the studies had ongoing radiological instability (3%) and both were associated with coronoid insufficiency. The mean flexion-extension arc ranged from 106° to 135° and pronation- supination arc ranged from 138° to 151°. The mean DASH scores ranged from 16 to 37.3 and the mean Broberg and Morrey Functional score from 68.2 to 93. Complication rates in the case series ranged from 21% to 40%, the commonest complications were heterotopic ossification, neuropathy and infections. Initial reports into the use of the Internal Joint Stabiliser for elbow instability have shown a low incidence of residual radiological joint incongruency.
