Improved Myelination following Camp Leg Power, a Selective Motor Control Intervention for Children with Spastic Bilateral Cerebral Palsy: A Diffusion Tensor MRI Study.

Background And Purpose: Children with spastic cerebral palsy have motor deficits associated with periventricular leukomalacia indicating WM damage to the corticospinal tracts. We investigated whether practice of skilled lower extremity selective motor control movements would elicit neuroplasticity.

Materials And Methods: Twelve children with spastic bilateral cerebral palsy and periventricular leukomalacia born preterm (mean age, 11.

Midflexion instability in revision total knee arthroplasty.

Midflexion instability is a new concept associated with revision total knee arthroplasty. It appears as rotational instability with combined external rotation and valgus stress in a knee flexed between 45 degrees and 90 degrees. Three main factors contribute to this instability: anterior medial collateral ligament attenuation, femoral-tibial articular geometry, and tibial post-femoral box geometry.

Patellofemoral arthroplasty with a customized trochlear prosthesis.

Successful patellofemoral arthroplasty depends on appropriate patient selection, proper prosthesis design, and correct surgical technique. Clinical results using off-the-shelf patellofemoral prostheses have reported mixed results primarily because of an inability to address these important characteristics adequately. This article reviews the design rationale, excellent clinical history, and straightforward surgical technique of a unique approach to patellofemoral arthroplasty that incorporates a customized trochlear prosthesis designed to fit the individual patient's patellofemoral groove.

Custom patellofemoral arthroplasty of the knee. Surgical technique.

Background: The treatment of isolated patellofemoral arthritis is controversial. Several surgical procedures have been used to treat the severely degenerated patellofemoral joint, with varying degrees of success. The purpose of this study was to determine the clinical results of a custom patellofemoral arthroplasty for the treatment of isolated patellofemoral degenerative arthritis of the knee.

Revision of failed arthroscopic bankart repairs.

Background: The results following open revision surgery following a failed arthroscopic Bankart procedure are not well documented.

Purpose: To evaluate the results of patients with a failed arthroscopic Bankart repair treated with a traditional, open Bankart repair.

Study Design: Case series; Level of evidence, 4.

UniSpacer arthroplasty of the knee.

Background: The operative treatment of medial compartment knee arthritis is controversial. The purpose of the present study was to report the experience of a single surgeon with the UniSpacer arthroplasty for the treatment of isolated medial compartment arthritis of the knee.

Methods: From April 2002 through November 2002, thirty-seven UniSpacer arthroplasties were performed in thirty-four patients for the treatment of arthritis that primarily involved the medial compartment of the knee.

Avoiding graft-tunnel mismatch in endoscopic anterior cruciate ligament reconstruction: a new technique.

A common problem encountered in endoscopic anterior cruciate ligament reconstruction is graft-tunnel mismatch. A technique not previously described in the literature is illustrated. This technique provides direct measurement of the tibial tunnel length plus the intra-articular distance.

Intraoperative decision making in the treatment of shoulder instability.

Between April 1990 and April 1994, 100 patients with a preoperative diagnosis of anterior instability underwent a diagnostic arthroscopy of the shoulder. Patients with isolated SLAP lesions were excluded from the study. Patients with multidirectional instability, bony Bankart lesions, and large Hill-Sachs lesions were also excluded.

Disassembly of a modular humeral prosthesis. A case report.

A modular humeral hemiarthroplasty utilizing a prosthesis with a taper-lock design was performed on a 77-year-old woman with a diagnosis of rotator cuff arthropathy. Radiographic examination at 3 months after surgery revealed disarticulation of the modular head and neck from the humeral prosthetic stem. This is a case report of a disarticulated modular humeral hemiarthroplasty.
