Complications of foot surgery. Nonunions and related disorders.

Management of malunions, delayed unions, and nonunions is a complex task that initially requires appropriate diagnosis and classification. Diagnostic modalities currently used include radiography, fluoroscopy, tomography, computed tomography, and radionucleotide evaluations. Based on these evaluations, nonunions may be classified as hypervascular or avascular in nature. Determining the presence of a synovial pseudoarthrosis or infection is also vital to nonunion management. Current treatment regimens available include combinations of cast immobilization, electrical stimulation, and surgical repair with and without bone graft. Internal and external fixation also provide rigid stability to promote healing of nonunion sites. Infected nonunions should be managed with appropriate surgical debridement and antibiotics. Internal fixation in the presence of infection may not necessarily need to be removed. There is no single best method for treatment of nonunions. Therapy must be tailored to each individual to provide a cure.

Z-bunionectomy with internal screw fixation.

A new procedure for the correction of hallux valgus was performed on 39 patients (66 feet). The follow-up period averaged 29 months, with a range of 24 to 32 months. The new procedure is a horizontally directed displacement Z-osteotomy in the head and shaft region of the first metatarsal. Rigid internal fixation is obtained with 3.5 or 2.7-mm bone screws. The surgeons' satisfaction rate of 79% compares favorably with the patients' complete satisfaction rate of 85%.

Prophylactic surgery in the diabetic foot.

Prophylactic surgery in the diabetic foot is often fraught with complications, according to a five-year retrospective study at the University of Chicago Hospitals and Clinics. The findings indicate that seven major areas need be addressed in order to properly evaluate the potential diabetic surgical patient. These include careful evaluation of preoperative nutritional status, vascular status, neurologic status, bacteriologic culture status, deformity status, radiologic status, and surgical predictive index.

Sports-related tendon injuries of the foot and ankle.

Treatment of major tendon injuries is a complex and challenging subject. It is necessary to have a thorough understanding of the mechanism of injury to successfully treat these soft tissue injuries of the foot and ankle.

Foot trauma in a rural hospital.

The authors made a survey of a rural hospital emergency room to determine the types of foot injuries seen and the frequency of foot injuries in relation to total emergency room visits. The study showed that foot fractures made up a significant portion of emergency room admissions.

Percutaneous transluminal angioplasty in the treatment of ischemic disease of the lower extremity.

Symptoms of severe peripheral vascular disease in the lower extremity necessitate attempts to revascularize the limb. Patients refusing or unable to undergo direct arterial surgery may be candidates for percutaneous transluminal angioplasty. Combined with realistic goals regarding foot salvage, careful selection of patients for angioplasty may prevent unnecessary amputations and permit local surgical care of the foot. Restoration of pain-free ambulation can follow the procedure. The coordinated efforts of various specialists can now be directed toward treatment of previously unmanageable ischemic complications in the foot.

Posterior tibial tendon rupture in a world class runner.

Complete rupture of the posterior tibial tendon occurs infrequently. It can be caused by a variety of factors, including repeated steroid injections, chronic tenosynovitis, and decreased blood supply to the tendon. The authors report a world class runner who sustained a rupture requiring surgical intervention.

The effect of a thigh tourniquet on the incidence of deep venous thrombosis after operations on the fore part of the foot.

We performed a prospective randomized clinical study to determine whether use of a thigh tourniquet influences the incidence of deep venous thrombosis. The lower limbs of patients who were scheduled for elective surgery on the fore part of the foot were randomized and assigned to one of three treatment categories: Group I, no tourniquet; Group II, exsanguination by an Esmarch bandage before tourniquet application; and Group III, exsanguination by elevation of the extremity prior to application of a tourniquet. The 117 limbs of seventy-one patients included in this study were evaluated preoperatively and twenty-four and seventy-two hours postoperatively with 125I-labeled fibrinogen, and preoperatively and seventy-two hours postoperatively with Doppler ultrasound studies and phleborheography. The findings in all of the Doppler ultrasound studies and all of the phleborheograms were normal. Two of the 125I-fibrinogen studies were positive, but subsequent contrast venography revealed that these were false-positive findings. We therefore concluded that the use of a thigh tourniquet does not increase the risk of deep venous thrombosis in patients who have had an operation on the fore part of the foot.

Peroneus longus tendinitis: a possible biomechanical etiology.

Tendinitis of the foot and ankle is becoming increasingly common, or at least more commonly recognized, with the recent widespread interest in running. In runners seen in our clinics we have encountered several cases of peroneus longus tendinitis. The authors present a case report and possible biomechanical etiology for peroneus longus tendinitis.

Acute gouty arthritis in a first metatarsophalangeal joint replaced with a flexible-hinge implant: a case report.

Use of the flexible-hinge, double-stemmed implant has eliminated many of the complications that followed correction of an arthritic first metatarsophalangeal joint caused by hallux valgus. There were no reports in the literature of acute gout after this type of correction. The authors present such a case in a patient with a history of gout, and they suggest that, when a synovectomy is performed in a patient with gouty arthritis, the joint should be freed of synovial tissue in which a uric acid crystal-induced synovitis could occur.

Subacute anterior tibial compartment syndrome.

Although acute anterior tibial compartment syndrome has been discussed frequently in the literature, there are few reports on the subacute or chronic syndrome. This problem may result from running or strenuous exercise, or even from walking. Additional demands are placed on the muscles of the anterior compartment by exercise, and this may result in varying degrees of symptomatology. Rest, elevation of the limb, and ice packs should be included in the treatment of this condition.

Patterns of lower-extremity injury in 224 runners.

Knee problems are the most common injury sustained in both male and female runners. Other problems include toe and forefoot injuries, inferior heel and arch pain, shin splints, ankle pain, calf and Achilles tendon pain, groin and hip pain, and stress fractures. The average total treatment for all injuries required 4.2 physician visits. Orthotics were used for more than 60% of the injuries, with successful results. A thorough understanding of running injuries should assist the physician in the treatment of these problems.

Effects of steroids on wound healing: a review of the literature.

Since some podiatric surgeons are using glucocorticosteroids to minimize postoperative edema and pain associated with traumatic procedures, the effects on wound healing should be understood as much as possible so that maximum results can be achieved with minimal risk to the patient. Considerable animal and human research has been done on the potential wound-healing effects of glucocorticosteroids. Current studies indicate a detrimental wound-healing effect with the use of glucocorticosteroids. Increased infection will also be discussed.
