The use of paratenon, polyethylene film, or silastic sheeting to prevent restricting adhesions to tendons in the hand.

We treated 132 patients by insertion of paratenon, polyethylene, or Silastic between a digital tendon and a bone, ligament, or fixed fascial structure to prevent adhesions. From 1950 to 1974, autogenous paratenon was used in thirty patients; from 1956 to 1965, polyethylene film was used in sixty-three patients; and from 1965 to 1974, Silastic sheeting was used in thirty-nine patients. By comparing the preoperative and postoperative measurements of joint motion and the changes in the distance separating the pulp of a finger from the palm during flexion, these patients were calssified as improved, unchanged, or worse. In some areas the material used appeared to make little difference, but in other areas one or the other was superior. Silastic sheeting (non-reinforced) proved to be the best material for most conditions, but it should not be employed when the skin is of poor quality or beneath a pedicle flap, and it should not be used adjacent to a tendon graft in an area that has recovered from an infection. Under those circumstances, paratenon is the preferred material.

Use of a hand-carved silicone-rubber spacer for advanced Kienböck's disease.

We found that the use of a hand-carved silicone-rubber (Silastic) spacer was reasonably effective in relieving symptoms in thirty-six patients with advanced Kienböck's disease, even though there was still some residual postoperative loss of wrist motion and grip strength. Preoperatively all patients had pain and limited motion of the wrist as well as weakness of grip. Roentgenographically all had fragmentation and collapse of the lunate, and 92 per cent had measurable carpal collapse. Most had had symptoms for longer than one year. After removal of the deformed lunate through a dorsal incision, a silicone-rubber spacer was shaped to fit the defect. Patients were followed for an average of fifty-four months. Thirty-two patients were followed for at least two years; all but three were improved. This procedure is not recommended when the shape of the lunate is normal or not significantly altered, or when the lunate has not collapsed as measured by precise determinants.

Capsulodesis of the metacarpophalangeal joint of the thumb in children with cerebral palsy.

A deformity of hyperextension of the metacarpophalangeal joint of the thumb occurring in thirteen children with spastic cerebral palsy was corrected by capsulodesis of the joint. The technique involves shifting the metacarpal attachment of the volar plate more proximally in the metacarpal. When combined with selective release of the involved intrinsic muscles and selective transfer of the extrinsic motors, when indicated, the thumb is brough away from the palm and its function and appearance are improved. Moreover, there is not risk to growth of the thumb such as might follow arthrodesis in a growing child. Results were satisfactory except in two athetoid patients, in whom some of the intial correction was lost, but even their thumbs did not revert into hyperextension. In five patients, for reasons not entirely clear, the previously flexed interphalangeal joint had better extension postoperatively. This improved the function of the thumb, because the broad pulp of the thumb could then be used firmly against the side of the index finger.

Treatment of ununited fractures of the scaphoid by iliac bone grafts and Kirschner-wire fixation.

Of 151 ununited fractures of the scaphoid that were treated with iliac bone grafts and Kirschner-wire fixation through a volar approach, all but four (97 per cent) healed in an average of seventeen weeks, Three of the four failures resulted from obvious technical errors. Neither the preoperative existence of necrosis of the proximal fragment nor the location of the fracture affected the results. When there was mild radiocarpal arthritis preoperatively, it did not progress postoperatively; if there was moderate radiocarpal arthritis preoperatively, progression seldom was seen if a radial styloidectomy was done. Displaced and unstable ununited fractures healed even if the deformity was not corrected completely. The principal benefit of the procedure was relief of pain rather than an increase either in motion of the wrist or in strength of grip.

Operative treatment of intra-articular fractures of the dorsal aspect of the distal phalanx of digits.

Thirty-six digits with an intra-articular fracture of the dorsal aspect of the distal phalanx that involved one-third or more of the articular surface were treated by open reduction and internal fixation with Kirschner wires. After an average length of follow-up of forty-six months, roentgenograms of the distal joint in twenty-six digits appeared essentially normal. Ten digits had minor roentgenographic changes but, with the exception of one digit, the joint space was congruous and free of significant abnormalities. The average loss of extension of the distal joint was 2 degrees, and the average arc of flexion of the distal joint was 69 degrees. The average strength of pinch in all digits that were operated on was essentially equal to the strength of pinch in the contralateral digit. Exact reduction and internal fixation using the technique described resulted in excellent motion and function.

Treatment of selected patients with an ununited fracture of the proximal part of the scaphoid by excision of the fragment and insertion of a carved silicone-rubber spacer.

An ununited scaphoid fracture whose proximal fragment is small, sclerotic, fragmented, or badly deformed is usually not suitable for bone-grafting. We treated twenty-one such patients by excision of the small proximal fragment through a volar incision and the insertion of a hand-carved silicone-rubber spacer. After surgery, twenty patients (95 per cent) were able to return to work and engage in strenuous activities, including sports. Pain was significantly relieved, although wrist motions and grip were only minimally improved. Preoperative and postoperative comparative measurements of carpal collapse and translation showed only insignificant changes after this procedure.

Fracture of the hook of the hamate in athletes.

During an eight-year period, four tennis players, seven golfers, and nine baseball players were seen with a fracture of the hook of the hamate. Eighteen of these twenty patients were disabled by pain and after the fracture fragment was removed, all eighteen were relieved so that they returned to their athletic pursuits. Two patients were asymptomatic, their old fracture being discovered accidentally when they were treated for other injuries. Nineteen of the twenty patients had been examined before coming under our care, but the correct diagnosis had been made in only two. Conservative treatment, including rest, physical therapy, and injections of steroids into the wrist and hand, had not been beneficial. From the history and findings, we believe that these fractures were caused by a direct blow against the hook of the hamate caused by the handle of the tennis racket, golf club, or bat during a swing, and not by indirect force produced by the ligaments and muscles attached to the hook. The fracture was demonstrated in all twenty patients by a roentgenogram (profile view) of the carpal tunnel.

Fusion of the first metacarpotrapezial joint for degenerative arthritis.

During a twelve-year period, twenty-eight patients (thirty thumbs) were treated for painful idiopathic arthritis of the metacarpotrapezial joint of the thumb by fusion. Failure of fusion occurred in two thumbs, and in both instances a solid fusion followed a second procedure. Fusion of the metacarpotrapezial joint did not predispose to painful arthritis of the trapezioscaphoid joint, even in patients with pre-existing roentgenographic evidence of minor degenerative changes in this joint. The results after long-term follow-up were gratifying, the patients having painless and stable thumbs with excellent strength. Although patients noted a minor loss of thumb motion, they did not consider this a problem. Fusion is a satisfactory procedure for patients who need or desire a strong, painless thumb, and seems especially worth while in the dominant thumb when both thumbs require surgical treatment.

Fracture of the hook of the hamate.

We removed the fracture fragment from fifty-nine patients who had an isolated fracture of the hook of the hamate. Preoperatively, all had complained of pain and tenderness on the ulnar side of the palm or on the dorsal ulnar aspect of the wrist. Most fractures were thought to have occurred while the patient was swinging a racquet, golf club, or baseball bat. Some fractures were caused by striking the palm on a solid object, by falling on the palm, or by a crush injury to the hand. Most of the fractures were diagnosed conclusively on a carpal tunnel roentgenogram or on a special oblique roentgenogram of the wrist supinated. We now believe that computed axial tomography is the best imaging technique for demonstrating this fracture. Except for two patients who had a crush injury, all of the patients returned to their regular occupational and athletic pursuits. There were no surgical complications.

Management of civilian gunshot injuries to the hip.

The orthopedic surgeon at a civilian trauma center is likely to encounter a gunshot injury to the hip. The nonmilitary literature regarding this injury gives few guidelines regarding an appropriate diagnostic evaluation or the indication for arthrotomy. We found that the best diagnostic test to detect joint penetration was hip aspiration followed by an arthrogram. Selected cases can be treated successfully with antibiotic therapy without an arthrotomy. These cases involve a low-velocity missile that passes through the joint, causes minimal bone disruption, and is free of bowel contaminants. If an arthrotomy is not performed, the physician must follow the patient with repeated physical examinations, complete blood counts, and a hip aspiration whenever infection is suspected. All transbdominal hip injuries require an immediate arthrotomy. In this series, bullets left in contact with joint fluid resulted in joint destruction or infection. Each patient with a displaced femoral neck fracture had a poor outcome with internal fixation. Hip arthroplasty or fusion should be considered as elective procedures for definitive management of these injuries.

Fractures and dislocations of the carpal bones.

The most common wrist fractures in athletes are fractures of the scaphoid and fractures of the hook of the hamate. Accurate diagnosis and conservative treatment are extremely important. A physician should not compromise principles of treatment for a rapid return of the athlete to competition, because all too often this will jeopardize eventual recovery and his or her future career. It is far better to be conservative, to insist upon complete recovery before permitting competition, especially in high-school and college students, and to be more concerned with the athlete's potential achievements than immediate accomplishments. These axioms are especially applicable when treating young individuals with suspected or proven wrist injuries.
