Stabilization of Recurrent Elbow Instability in the Presence of Hyperlaxity in Children Using a Nonanatomic Soft Tissue Reconstruction.

Despite growing concordance of opinion in the adult setting, pediatric elbow instability and its management are poorly represented in the literature due to its low prevalence and often unique circumstances. The authors present a case of posttraumatic recurrent posterior pediatric elbow instability in a patient with joint hypermobility. Our patient, a 9-year-old girl, sustained a right-sided supracondylar fracture of the humerus in April 2019. Having been managed operatively, the elbow remained unstable and dislocated posteriorly in extension. Definitive surgical management was designed to provide a stable functional elbow. The principle of the surgery was to create a checkrein of tissue, not changing in length in extension and flexion, and to prevent further posterior elbow instability. A 3 mm slip of the central triceps tendon was dissected, leaving its attachment to the olecranon tip. Gracilis allograft was sutured to the strip of the triceps tendon to increase the tensile properties of the native tendon graft using a braided nonabsorbable suture. The tendon construct was then passed through a window made in the olecranon fossa and a transosseous tunnel in the ulna from the coronoid tip to the dorsal cortex. The tendon was tensioned and secured to the radial-dorsal aspect of the ulna with a nonabsorbable suture anchor in 90 degrees of flexion. At one year follow-up, the patient has a stable and pain-free elbow joint with no functional limitations.

Reverse shoulder arthroplasty versus hemiarthroplasty versus non-surgical treatment for older adults with acute 3- or 4-part fractures of the proximal humerus: study protocol for a randomised controlled trial (PROFHER-2: PROximal Fracture of Humerus Evaluation by Randomisation - Trial Number 2).

BACKGROUND: Proximal humerus fractures (PHF) are common and painful injuries, with the majority resulting from falls from a standing height. As with other fragility fractures, its age-specific incidence is increasing. Surgical treatment with hemiarthroplasty (HA) and reverse shoulder arthroplasty (RSA) have been increasingly used for displaced 3- and 4-part fractures despite a lack of good quality evidence as to whether one type of arthroplasty is superior to the other, and whether surgery is better than non-surgical management. The PROFHER-2 trial has been designed as a pragmatic, multicentre randomised trial to compare the clinical and cost-effectiveness of RSA vs HA vs Non-Surgical (NS) treatment in patients with 3- and 4-part PHF. METHODS: Adults over 65 years of age presenting with acute radiographically confirmed 3- or 4-part fractures, with or without associated glenohumeral joint dislocation, who consent for trial participation will be recruited from around 40 National Health Service (NHS) Hospitals in the UK. Patients with polytrauma, open fractures, presence of axillary nerve palsy, pathological (other than osteoporotic) fractures, and those who are unable to adhere to trial procedures will be excluded. We will aim to recruit 380 participants (152 RSA, 152 HA, 76 NS) using 2:2:1 (HA:RSA:NS) randomisation for 3- or 4-part fractures without joint dislocation, and 1:1 (HA:RSA) randomisation for 3- or 4-part fracture dislocations. The primary outcome is the Oxford Shoulder Score at 24 months. Secondary outcomes include quality of life (EQ-5D-5L), pain, range of shoulder motion, fracture healing and implant position on X-rays, further procedures, and complications. Independent Trial Steering Committee and Data Monitoring Committee will oversee the trial conduct, including the reporting of adverse events and harms. DISCUSSION: The PROFHER-2 trial is designed to provide a robust answer to guide the treatment of patients aged 65 years or over who sustain 3- and 4-part proximal humeral fractures. The pragmatic design and recruitment from around 40 UK NHS hospitals will ensure immediate applicability and generalisability of the trial findings. The full trial results will be made available in a relevant open-access peer-reviewed journal. TRIAL REGISTRATION: ISRCTN76296703. Prospectively registered on 5th April 2018.

Late presentation of a partial median nerve palsy following a Gartland III supracondylar humeral fracture.

A 28-year-old male patient was referred to the Peripheral Nerve Injury Unit at the Royal National Orthopaedic Hospital for evaluation and treatment of a neuropathic type pain he had developed in his right arm. Some twenty years previously, he had sustained a Gartland type III supracondylar humeral fracture with what was thought clinically to be an anterior interosseous nerve palsy. The fracture was reduced and the nerve palsy subsequently recovered with non operative measures. At his subsequent delayed presentation, surgical exploration revealed that the median nerve epineurium was embedded within the bone at the level of the previous fracture. A good clinical result was obtained following neurolysis. The case report highlights a late presentation of median nerve palsy following interposition of the neural structure within the reduced distal humeral fracture site; it shows that delayed surgery can be effective.
