Dislocations of the elbow - An instructional review.

Dislocations of the elbow require recognition of the injury pattern followed by adequate treatment to allow early mobilisation. Not every injury requires surgery but if surgery is undertaken all structures providing stability should be addressed, including fractures, medial and lateral ligament insertion and the radial head. The current concepts of biomechanical modelling are addressed and surgical implications discussed.

Clinical anatomy and biomechanics of the elbow.

The anatomy of the elbow joint had been studied extensively over the last 2 decades. The increased understanding of the anatomy and contribution of the anatomical structures to the elbow biomechanics had enabled surgeons to improve the results of surgical reconstruction and fracture fixation. This review articles intend to summarise the salient functional and clinical anatomical and relevant biomechanical data that had been published recently.

Radial head fractures.

Radial head fractures are the commonest fractures in the elbow. They are often associated with other injuries: ligamentous, cartilaginous or other fractures. Associated injuries are important determinant of the management of the radial head fracture. These should be carefully looked for, diagnosed and treated. The original Mason classification for this fracture has been modified to include the associated injuries and their treatment. CT scan is a helpful diagnostic tool and should be used if available. Radial head fractures can be treated either conservatively or operatively (by excision, open reduction and internal fixation or prosthetic replacement). Undisplaced or minimally displaced fractures should be treated non-operatively. Internal fixation by headless cannulated screws is the preferred treatment for displaced fractures. It provides satisfactory biomechanical stability, can be done through a smaller incision, has less complications and lesser requirement of later removal of screws. Small number of fractures with comminution of neck would require plate fixation. Unfixable fractures in elderly can be treated by excision while such fractures in younger population or associated with significant soft tissue or bony injuries would require prosthetic replacement.

The flail elbow: Every surgeon's nightmare.

A flail elbow joint has an excessive or abnormal degree of mobility resulting in loss of function. Such a situation can arise from structural damage or loss of neuromuscular control. Structural damage may be in terms of loss of integrity of bony, ligamentous, or both components, and this is commonly caused by trauma, failed arthroplasty, infections - either in the native joint or associated with the above, or inflammatory arthritides. Arm paralysis from any cause may also leads to a loss of muscle control making the elbow flail. The management of the condition varies according to etiology; and concurrent issues like infection and instability need to be addressed in addition to the structural problems. Treatment can be non-surgical with the use of orthotics to support the elbow, and maybe more appropriate in certain circumstances. Surgical treatment can involve fixation, repair or reconstruction. Often the deficiency is not amenable to these methods and arthroplasty has to be considered. The situation becomes more fraught in case of failure of arthroplasty and/or infection, where reconstruction can be challenging. In this review we have considered diverse clinical scenarios that fall under this broad umbrella, with a focus on those encountered commonly in practice.

Complications of modern design total elbow replacement.

Total elbow arthroplasty is an important surgical option for advanced arthritis of the elbow. Semi-constrained linked prosthesis is still a popular choice, however, complications and revisions after TER remain high. Aseptic loosening and infection are two most common mode of failure. Periprosthetic fracture, implant failure, and triceps insufficiency have also been reported. Revision arthroplasty needs careful preoperative planning to tackle deficiency in soft tissue and osseous structure. Impaction, strut allograft or allograft prosthesis composite graft should be considered for failed TER.

Nerve entrapment around elbow.

Entrapment neuropathy around elbow is a common cause of disability across all age groups. The major nerves that traverse the elbow are ulnar, median and radial nerves and their branches. Cubital tunnel syndrome leading to ulnar nerve compression can often present with significant pain, paresthesia or weakness. Median and Radial nerve compression around the elbow, albeit less frequent, can also lead to significant morbidity and must be kept in the differential diagnosis when dealing with patients complaining of persistent pain around the elbow and weakness of forearm/hand muscles. Electrodiagnostic studies can be a useful adjunct to clinical examination, to help localize the site and quantify the grade of compression. Management should involve a trial of conservative treatment and failing that, surgical treatment should be considered. We hereby provide an overview of nerve entrapments around the elbow including their applied anatomy, etiology, clinical assessment and overview of the current concepts in surgical treatment.

Management of Orthopaedic Injuries in Multiply Injured Child.

Multiply injured child is a unique challenge to the medical communities worldwide. It is a leading cause of preventable mortality and morbidity in children. Common skeletal injuries include closed or open fractures of tibia and femur and pelvic injuries. Initial management focuses on saving life and then saving limb as per pediatric advanced life support and advanced trauma life support. Orthopedic management of open fracture includes splinting the limb, administration of prophylactic antibiotic, and surgical debridement of the wound when safe. However, gross contamination, compartment syndrome, and vascular injuries demand urgent attention.

Glomus tumour of the elbow: an unusual complication of surgery.

Glomus tumours of the elbow remain a challenge to diagnose correctly and efficiently. We present a case of a glomus tumour as a complication of elbow surgery. This has not been described previously. This case highlights the possibility of injury as a causative factor in these tumours and the difficulty in differentiating them from postoperative neuromas by clinical presentation and ultrasound imaging alone.

Intensive rehabilitation combined with HBO2 therapy in children with cerebral palsy: a controlled longitudinal study.

OBJECTIVE: The present study aimed to assess the effect of intensive rehabilitation combined with hyperbaric oxygen (HBO2) therapy on gross motor function in children with cerebral palsy (CP). METHODS: We carried out an open, observational, platform-independent study in 150 children with cerebral palsy with follow-up over eight months to compare the effects of standard intensive rehabilitation only (control group n = 20) to standard intensive rehabilitation combined with one of three different hyperbaric treatments. The three hyperbaric treatments used were: air (FiO2 = 21%) pressurized to 1.3 atmospheres absolute/atm abs (n = 40); 100% oxygen pressurized at 1.5 atm abs (n = 32); and 100% oxygen, pressurized at 1.75 atm abs (n = 58). Each subject assigned to a hyperbaric arm was treated one hour per day, six days per week during seven weeks (40 sessions). Gross motor function measure (GMFM) was evaluated before the treatments and at two, four, six and eight months after beginning the treatments. RESULTS: All four groups showed improvements over the course of the treatments in the follow-up evaluations (p < 0.001). However, GMFM improvement in the three hyperbaric groups was significantly superior to the GMFM improvement in the control group (p < 0.001). There was no significant difference between the three hyperbaric groups. CONCLUSION: The eight-month-long benefits we have observed with combined treatments vs. rehabilitation can only have been due to a beneficial effect of hyperbaric treatment.
