Current state of flexor tendon surgery.

Successful restoration of function after flexor tendon injuries continues to present a challenge to the treating surgeon. Primary repair of tendon and associated injuries is the treatment of choice in clean wounds in all zones of the hand. In cases of untidy wounds or when associated injuries preclude primary repair, delayed primary or secondary repair may be performed. Tendon grafting in one or two stages is reserved for late secondary cases in which scarring of the bed, loss of pulleys, permanent retraction of the tendon ends, or joint contractures prevent direct repair. Meticulous attention to detail such as adequate exposure, careful opening and closing of the sheath, gentle handling of the tendons, a secure, smooth tendon juncture and proper postoperative splinting is essential for a successful outcome of direct repair. Tendon grafts done as a secondary procedure require the same attention to minutiae for an adequate functional outcome.

Clinical features of renovascular hypertension in infancy: report of a 9-month-old infant.

Certain common but seldom recognized clinical features of renovascular hypertension peculiar to infancy are emphasized in this communication from the observations made in a 9-month-old infant. Failure to thrive, extreme irritability, hypotonia, anorexia, vomiting, diarrhea, respiratory distress, and congestive heart failure are common clinical findings. Unless the physician is aware of this symptomatology or blood pressure is routinely obtained in all infants, the condition is likely to be missed. Renovascular hypertension is malignant and carries a high mortality but if diagnosed early may be cured by surgical intervention.

Uncommon nerve compression syndromes of the upper extremity.

Nerve compression syndromes are a common cause of pain, sensory disturbance, and motor weakness in both the upper and the lower extremities. Although carpal tunnel syndrome is frequently diagnosed and treated surgically with success, other compression syndromes are less common and are often best treated nonsurgically. Understanding the anatomy of the major peripheral nerves with respect to intermuscular septa, fibrous bands, muscle margins, and internervous planes is crucial to understanding how and where peripheral nerve compression can occur. Some conditions, such as anterior interosseous nerve syndrome, respond well to nonoperative treatment; others, such as posterior interosseous nerve syndrome, are better treated by surgical intervention. The authors discuss the anatomic and pathologic causes for compression syndromes, as well as guidelines for treatment and outcomes.

Conversion of ankylosed hips to total hip arthroplasty.

Between 1970 and 1979, 17 patients underwent conversion of ankylosed hip to total hip arthroplasty. The patients' ages ranged from 38 to 82 years and the duration of fusion prior to conversion ranged from five to 60 years. The primary indication for conversion to total hip replacement in all patients was disabling pain in the low back, the ipsilateral knee, and the contralateral hip. The reason for ankylosis varied: five patients had previously undergone fusion for posttraumatic arthritis, two patients for tuberculous arthritis, six patients for osteoarthritis, one for a previous old slipped capital femoral epiphysis which had undergone spontaneous fusion after internal fixation, and two patients for ankylosing spondylitis. Relief of preoperative pain in the lower back was seen in 12 of 13 patients, knee pain was relieved in four out of four patients, and contralateral hip pain was relieved in seven out of 10 patients. Complications included heterotopic ossification, infection, perforation of the posterior shaft of the femur, and failure of trochanteric fixation with subsequent dislocation. Predictable pain relief from pain in the contralateral hip was less predictable and directly related to the degree of osteoarthritis in the contralateral hip. In these patients it is suggested that conversion of the fused hip to total hip arthroplasty be staged with total hip replacement in the contralateral hip as well. The end results were least satisfactory in patients with ankylosing spondylitis.
