METHODS: We report a case of progressive angular deformity of the left wrist in a 4-year-old girl with a 2-year history of juvenile idiopathic arthritis (JIA)-oligoarthritis subtype (<4 joints affected) with inflammatory extensor tenosynovitis affecting the left wrist, who underwent a left distal radius osteotomy with tricortical allograft for angular correction and functional recovery. Six years postoperatively, the patient demonstrates a near-anatomic left wrist and has recovered full range of motion and function.
CONCLUSIONS: This case demonstrates how rare clinically devastating angular deformities in JIA may safely and effectively be surgically managed to promote normal, long-term, extremity function.

METHODS: A 32-year-old woman with bilateral Madelung deformity presented with severe pain and arthritis of the radiocarpal and distal radioulnar joints. At final follow-up, 17 months for the left and 12 months for the right wrist, she had excellent functional results with no pain. Range of motion was 30° of flexion and 30° of extension with full pronosupination.
CONCLUSIONS: There is paucity in the literature regarding salvage procedures in adults with this deformity. We demonstrate treatment with distal ulna excision and an radioscapholunate arthrodesis. This procedure may be indicated in Madelung deformity and proximal radiocarpal and distal radioulnar joint arthritis.

METHODS: A 71-year-old female patient presented with severe glenoid bone loss and deformity after 2 subsequent failed arthroplasty procedures because of baseplate failures. The patients then underwent a conversion from reverse shoulder arthroplasty to hemiarthroplasty, while using a distal radius allograft to augment the deformed glenoid. At the 2-year follow-up, the patient reported minimal pain and satisfactory outcomes.
CONCLUSIONS: This case presents the distal radius as a potentially useful allograft option for augmenting severe glenoid bone loss in the setting of revision shoulder arthroplasty.

Congenital pseudarthrosis of the forearm poses a considerable challenge because of its rarity. The objective of this report is to introduce a novel surgical technique for its treatment. Here, we document a case of congenital pseudarthrosis of the radius in a 3-year-old boy diagnosed with type-1 neurofibromatosis. The surgical treatment involved the excision of approximately 9 cm of native radial periosteum and a bifocal radius osteotomy, which was supplemented with a vascularized tibial periosteal transplant to facilitate bone healing. Anastomosis between the anterior tibial vessels and radial vessels was performed. No immediate or late postoperative complications were observed. After 3 weeks, a robust callus formation was observed, and during a follow-up examination 3 years and 4 months later, a wide range of active forearm rotation was noted. This report suggests that vascularized periosteal flaps show promise as a viable treatment option for congenital pseudarthrosis of the forearm. They offer an alternative to vascularized fibular grafts or single-bone forearm constructs.

Congenital radial head subluxation is relatively rare and may be overlooked due to mild symptoms. The diagnosis mainly relies on imaging and history. Observation is an option for those with insignificant symptoms, while surgical intervention, such as ulnar osteotomy or arthroscopy, is often required when dysfunction exists. A 30-year-old man was admitted with congenital radial head dislocation, which was treated with manipulative repositioning. During follow-up, the patient regained the original mobility of the elbow joint and had no recurrence of dislocation. In conclusion, in adults with congenital dislocation of the radial head, we recommend conservative treatment as a first step.

We experienced an atypical case of radial longitudinal deficiency that did not fit into any classifications, including Blauth. The patient had a bilateral hypoplastic thumb, in which the index and middle fingers were missing in the right hand. We performed surgeries in four stages: centralization of the right hand, opponensplasty of the right thumb, opponensplasty of the left thumb, and distraction lengthening of the right ulnar. Twenty-five years after the initial treatment, the patient was satisfied with the treatment and had no significant difficulty with activities of daily living.

BACKGROUND: Radial neck fractures account for 5-17% of elbow fractures and about 1% of all fractures in children. The subject of the presented research is assesment of clinical and radiological outcomes of the Metaizeau technique for treatment of isolated radial neck fractures in children.
METHODS: Retrospective analysis of clinical and radiological data of patients treated with the Metaizeau technique in our Department between 2015 and 2020. Twenty children with isolated radial neck fracture met the inclusion criteria.
RESULTS: Excellent outcomes of operative treatment were achieved in 95% of children. None of the complications described in the literature (e.g. avascular necrosis of radial head (AVN), malunion, nonunion) were observed in our case series.
CONCLUSIONS: 1. The Metaizeau technique for reduction and stabilisation of the radial neck fracture using a TEN is a safe and effective method in the paediatric population and produces good clinical and radiological results. 2.Furthermore, the minimal demands it places on surgical equipment make it possible for this technique to be recommended to orthopaedic surgeons managing paediatric trauma patients.

In conflict zones like Syria, accessing specialized medical care presents significant challenges. Here, we present the case of a 22-year-old female with a giant cell tumor in her distal forearm, exacerbated by limited access to healthcare due to the Syrian conflict. Despite these obstacles, we successfully performed en bloc resection and reconstructed the defect with a proximal non-vascularized fibular graft, restoring arm function. This case underscores the critical importance of adapting to adverse circumstances to deliver essential medical interventions in conflict-affected regions.

The complete loss of finger extension leads to significant inconvenience in daily life and often requires surgical treatment. Despite some disadvantages, the Boyes method, which uses the flexor digitorum superficialis tendon, is commonly performed for complete extensor rupture. We report the case of a 73-year-old woman living alone diagnosed with a subcutaneous rupture of all extensor tendons from the index to the little finger. The favourable range of motion of her wrist allowed us to perform extensor tenodesis. Additionally, the patient had a dislocated thumb interphalangeal (IP) joint, enabling us to use the extensor pollicis longus tendon for tendon transfer in combination with thumb IP joint fusion. The patient demonstrated favourable finger range-of-motion outcomes at the 6-month postoperative assessment. The case shows that extensor pollicis longus tendon transfer and tenodesis may be a viable treatment option for patients with complete extensor rupture accompanied by thumb IP joint deformity and normal wrist range of motion.
