Clinical treatment of partial tendon lacerations without suturing and with early motion.

Partial lacerations of flexor tendons in chickens come out the strongest and glide best if they are not sutured and not immobilized. We treated 17 patients with 20 partial flexor tendon lacerations by not suturing the tendon and by early mobilization of the digit. These partial tendon lacerations varied from 25 to 95 percent of the cross-sectional area. Sixteen of obtained excellent function of the digit, and one obtained good to excellent function. This technique should be used only in cooperative patients.

Rate and extent of functional recovery after flexor tendon grafting with and without silicone rod preparation.

Forty-six consecutive patients requiring flexor tendon grafts were evaluated at 4, 6, 8, 10, 12, 16, 20, 22, 24, 28, 34, and 52 weeks after grafting. The patients were divided into two groups: those who did not require a silicone rubber rod prior to tendon grafting (Group I), and those who did require a silicone rubber rod prior to grafting (Group II). Analysis of the rate of functional recovery as measured by total active motion, gross grip strength, and pinch grip strength showed no significant difference between the two groups. Analysis of the extent of functional recovery at one year, as measured by total active motion and distance of digital pulp from distal palmar crease, showed no significant differences between Groups I and II.

Lateral-volar finger flap for the treatment of burn syndactyly.

To completely open the web space in burn syndactyly and provide tissue that is pliable and elastic, we describe a flap from the lateral and volar surfaces of an adjacent finger which will completely cover the opened defect. The results of this procedure in 24 web spaces are reported.

The Byars hypospadias repair. A review of 253 consecutive patients.

Of 253 consecutive hypospadias repairs by various surgeons, using the Byars technique, 57 (22 percent) had postoperative fistulae; 41 required one operation, 9 required two operations, and 7 required more than two operations for closure of these fistulae. Other complications were infrequent. When performed either by attending or resident physicians, the Byars hypospadias repair produced complete correction of the chordee, a urethra of satisfactory length and caliber, normal penile appearance, and a fistula rate comparable to that reported after other procedures.

Treatment of cystic hygroma.

To determine ideal treatment, 58 patients with cystic hygroma of the neck were studied. Approximately equal distribution of the lesion among sexes and sides of the neck was noted, but frequency was less than expected among blacks. Complete excision, the treatment of choice, gave an 81% cure rate. Partial excision was curative in only 12% of cases, but it decreased the tumor mass enough to eliminate the need for further treatment in 62% of cases. Aspiration of the cysts may be of value in diagnosis and management of acute respiratory problems but not for definitive therapy. Sclerosing agents and radiation therapy was not effective treatment of cystic hygromas. Of the clinical recurrences, 76% occurred within a year after therapy.

Secondary correction of nasal abnormalities associated with cleft lip.

Approximately 30% of patients will require a second operation for correction of nasal abnormalities associated with unilateral cleft lip. In a single second operation, the following steps seem to give the most satisfactory correction: repositioning the nasal septum in the midline; altering the contour of the alar cartilage on the cleft side; and rotation of the axis of the external naris on the cleft side. The usual result following this combination of procedures is moderate but not complete correction of the abnormality. About 50% of the patients will need a second operation for correction of nasal abnormalities associated with bilateral cleft lip. Satisfactory correction of the bilateral cleft lip nasal deformity is usually obtained by lengthening the columella (which secondarily corrects a flat nasal tip) and narrowing the width of the nose at the level of the alae. Satisfactory restoration to normal is usually obtained by the aforementioned procedure.

Spontaneous regression of the primary lesion of a metastatic maligvant melanoma.

An atypical elderly patient with spontaneous regression of a primary lesion of malignant melanoma is presented. The 12 previously reported cases are also reviewed. The histological diagnosis of spontaneous regression of a melanoma can still be made after the regression appears to be grossly complete. All localized areas of depigmentation, or of scarring, should be biopsied when searching for an "occult" primary.
