Anterior Longitudinal Ligament Reconstruction to Reduce Hypermobility of Cervical and Lumbar Disc Arthroplasty.

Conclusions: ALL reconstruction following cervical and lumbar disc arthroplasty is a promising solution to addressing non-physiological kinematics of current disc arthroplasty devices. Randomized, controlled studies with larger study samples and long-term follow-up are required to establish these conclusions. PMID: 29279750 [PubMed]

Abstract BACKGROUND: The Bernese periacetabular osteotomy (PAO) is one of the most-used surgical techniques to treat symptomatic acetabular dysplasia. Although good functional and radiographic short-term and long-term outcomes have been reported, several complications after PAO have been described. One complication that may compromise clinical results is nonunion of an osteotomy. However, the exact prevalence and risk factors associated with nonunion are poorly elucidated. QUESTIONS/PURPOSES: (1) What proportion of patients have complete bony healing versus nonunion during the first year after PAO? (2) What i...

CONCLUSIONS: Our findings are concerning because the revision risk with this constrained reverse total shoulder implant was higher than has been reported by others for other proximal humerus prostheses. The highly constrained design that helps prevent instability might also transmit increased stresses to the humeral component-bone interface, therefore making it susceptible to loosening. We believe that any other implant with a similar degree of constraint will have the same problem, and changing the indications for patient selection may not solve this issue. These theories need to be tested biomechanically, but our desire ...

Conclusion: Addition of fibula allograft to patients sustaining varus-angulated, 2- and 3-part proximal humeral fractures conferred no benefit to patient outcomes at our institution. Level of Evidence: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Conclusion: Interbody fusion and percutaneous reduction with MMED provides a minimally invasive procedure for lumbar spondylolisthesis, with sufficient decompression, reduction, fusion, and satisfactory clinical results.

Conclusions: For one-level ACDF, the anchored cage with screws has some advantage compared to the stand-alone PEEK cage in avoiding dysphagia and restoring disc space height and cervical lordosis. We suggest the anchored spacer may be a good substitute for the stand-alone cage in one-level ACDF. Level of Evidence: Level II

Conclusion: Our data showed that the new allograft cage is superior to the PEEK cage in providing a high fusion rate and fewer complications after 1-level and 2-level ACDF procedures. It may represent an excellent alternative to other cages.

We described a case of open proximal phalangeal fracture with bone defect of the left index finger due to dog bite injury. The patient was treated successfully with a pedicled second metacarpal vascularized bone graft based on the second dorsal metacarpal artery following debridement and external fixation. Subsequently, extensor tendon tenolysis wrapped with adipofascial flap based on the first dorsal metacarpal artery was performed. After obtaining supple joint of the finger, flexor tendon tenolysis was performed. The postoperative course was uneventful, without infection. Nineteen months after the last operation, there w...

Discussion Distal scaphoid excision should be preferred to improve the functional results while decreasing scaphotrapeziotrapezoidal osteoarthritis and radiocarpal nonunion rates. Excision of the triquetrum appears to be an alternative to radioulnar resection–arthroplasty to solve ulnocarpal impaction syndrome. Strict surgical procedure must be observed to promote RSL fusion combining solid bone fixation and the use of bone graft. Level of evidence This is a level IV, case series, retrospective series.

Conclusion: Biological restoration of elbow anatomy using osteoarticular irradiated graft for proximal ulna reconstruction offers great joint stability and functional outcomes. Although the potential risks of infection and graft failure need to be considered, reconstruction with the size-matched radiated autograft eliminates donor site morbidity, offers a low-cost alternative to endoprosthesis, and provides outcomes superior to any other methods of reconstruction as analyzed from the literature.
