Elbow arthroscopy.

Elbow arthroscopy has made rapid advances in recent years. The improvement in the arthroscopic technique, as well as the development of technically advanced equipment, has made elbow arthroscopy very attractive to orthopaedic surgeons. It is important to realize that elbow arthroscopy is a modality that should be respected. This demanding procedure requires keen awareness of the elbow's anatomy and the technical arthroscopic approach to the elbow joint. With this careful approach in mind, the orthopaedist will find that elbow arthroscopy can be a valuable tool.

The lateral trochlear sign. Femoral trochlear dysplasia as seen on a lateral view roentgenograph.

Dysplasia of the femoral trochlea is easily detected on an axial roentgenogram of the patellofemoral joint. A roentgenographic sign is described wherein severe trochlear dysplasia can also be readily appreciated on a plain lateral roentgenogram. The subchondral bone of the trochlea is normally seen as a dense white line, which remains parallel to the subchondral bone of the lateral femoral condyle. The intersection of those two lines is indicative of severe trochlear dysplasia and has been named "the lateral trochlear sign."

Bicondylar tibial plateau fracture complicated by compartment syndrome.

Compartment syndrome complicating tibial shaft fractures is a well-documented entity. However, the complication of compartment syndrome after tibial plateau fracture as described in this paper is relatively rare because of dissipation of tissue pressures into the knee-joint compartments. A thorough surgical decompression of all four compartments with continuous postoperative monitoring of compartment pressures was accomplished before the patient's fracture was stabilized. This strategy of delayed reconstruction of the tibial plateau worked well in this patient.

Tarsal tunnel syndrome secondary to neurilemmoma.

Neurilemmoma is an uncommon cause of tarsal tunnel syndrome, and no other cases of this disorder secondary to a lesion at the bifurcation of the medial and lateral plantar nerves have been described. In this case, a 2 x 0.5 x 1-cm mass was palpable on physical examination, and, after failed conservative treatment, surgical excision brought prompt relief of symptoms.

Using the Brazelton Neonatal Assessment Scale to facilitate the parent-infant relationship in a primary care setting.

This article describes use of the Brazelton Neonatal Assessment Scale (BNAS) as an effective parent-teaching tool and demonstrates how this tool can be successfully integrated into a primary care setting. Research indicates that the BNAS can be used to enhance parent-infant bonding, to promote parents' confidence, and to intervene in potentially dysfunctional parent-infant interactions before poor parenting patterns become well established. Case studies exemplify how a clinician can use the BNAS to evaluate 37 newborn behaviors and 18 neurological reflexes, identifying the newborn's individual strengths, elucidating coping behaviors (as he or she strives to maintain control over the autonomic nervous system), illuminating his or her individual stress responses, and demonstrating which comforting techniques are most effective for that child. Further case studies illustrate how the tool can enable a clinician to identify the positive characteristics of a difficult baby, and emphasize the importance of noticing and responding appropriately to a baby's state of consciousness. The BNAS is an effective interactional exam because the clinician captures the patients' attention by interacting with their newborn. During this interaction the clinician assesses and describes the newborn's strengths and needs, and at the same time models effective interaction with the infant. Samples of the BNAS scoring protocol and a helpful parent-education handout are included.

Newborn circumcision.

Newborn circumcision is the most common surgical procedure in the United States today. The decision to circumcise is deeply rooted in historical, psychosocial, and medical fact and fiction. Many parents are uninformed about the risks of circumcision, think circumcision is required by law, and receive inaccurate or insufficient instruction on the care of the uncircumcised child. Nurses need to present accurate information to parents and to help them sort through beliefs and feelings on circumcision. The nurse then needs to support the parents' decision.
