ReviewStandard surgical protocol to treat elbow dislocations with radial head and coronoid fractures. Surgical technique.
The results of elbow dislocations with associated radial head and coronoid fractures are often poor because of recurrent instability and stiffness from prolonged immobilization. We managed these injuries with a standard surgical protocol, postulating that early intervention, stable fixation, and repair would provide sufficient stability to allow motion at seven to ten days postoperatively and enhance functional outcome. ⋯ Use of our surgical protocol for elbow dislocations with associated radial head and coronoid fractures restored sufficient elbow stability to allow early motion postoperatively, enhancing the functional outcome. We recommend early operative repair with a standard protocol for these injuries.

ReviewTreatment of osteonecrosis of the femoral head with implantation of autologous bone-marrow cells. Surgical technique.
Aseptic nontraumatic osteonecrosis of the femoral head is a disorder that can lead to femoral head collapse and the need for total hip replacement. Since osteonecrosis may be a disease of mesenchymal cells or bone cells, the possibility has been raised that bone marrow containing osteogenic precursors implanted into a necrotic lesion of the femoral head may be of benefit in the treatment of this condition. For this reason, we studied the implantation of autologous bone-marrow mononuclear cells in a necrotic lesion of the femoral head to determine the effect on the clinical symptoms and the stage and volume of osteonecrosis. ⋯ Implantation of autologous bone-marrow mononuclear cells appears to be a safe and effective treatment for early stages of osteonecrosis of the femoral head. Although the findings of this study are promising, their interpretation is limited because of the small number of patients and the short duration of follow-up. Further study is needed to confirm the results.

ReviewLigament reconstruction with or without tendon interposition to treat primary thumb carpometacarpal osteoarthritis. Surgical technique.
Trapezial excision with ligament reconstruction and trapezial excision with ligament reconstruction combined with tendon interposition have proven to be highly effective techniques for treating primary osteoarthritis of the thumb carpometacarpal joint. To determine whether tendon interposition and proximal migration of the thumb metacarpal affect the objective and subjective outcomes, we compared the long-term outcomes of these two procedures performed in similar patient groups. ⋯ Tendon interposition does not affect the outcome after the ligament reconstruction for the treatment of osteoarthritis of the thumb carpometacarpal joint. Furthermore, proximal migration of the thumb metacarpal does not appear to influence the functional outcome.

ReviewManagement of Mason type-III radial head fractures with a titanium prosthesis, ligament repair, and early mobilization. Surgical technique.
Radial head fractures often occur in association with other elbow fractures and soft-tissue injuries. Radial head replacement is indicated for irreparable radial head fractures associated with elbow instability. The purpose of this study was to analyze the results after treatment of such injuries with a titanium radial head prosthesis, repair of torn collateral ligaments, and early mobilization of the elbow. ⋯ The results of treatment of Mason type-III radial head fractures with a monoblock titanium radial head prosthesis and soft-tissue reconstruction are satisfactory. Early mobilization of the elbow is important for the restoration of elbow range of motion and function.

Posterior shoulder dislocations and fracture-dislocations are uncommon injuries that most often occur during seizures or as a result of high-energy trauma. Despite advances in imaging, they are frequently diagnosed late. Detection is facilitated by heightened clinical suspicion of the injury in high-risk individuals together with appropriate radiographic investigation. ⋯ Because of the rarity of these injuries, evidence-based treatment protocols are difficult to devise. Good functional outcomes are associated with early detection and treatment of isolated posterior dislocations that are associated with a small osseous defect and are stable following closed reduction. Poor prognostic factors include late diagnosis, a large anterior defect in the humeral head, deformity or arthrosis of the humeral head, an associated fracture of the proximal part of the humerus, and the need for an arthroplasty.
