Posterior roentgenogram of the foot.

Abstract: A present there is no reliable way to define the position of the heel in relationship to the tibia during weight bearing. Many surgical and nonsurgical procedures are done to correct a varus or valgus heel without a standard method to define the problem or measure the results. This is a report on a posterior roentgenographic technique which defines the position of the heel with respect to the talus, tibia, and forefoot. This technique allows for measurement of the position of the heel and can be performed in any X-ray facility.

Therapeutic foot and leg protector

Abstract: A therapeutic foot and leg protector comprises a rigid outer shell having a soft protective liner disposed therein. The protector is perforated in its heel portion to allow air to enter the shell and circulate about the heel of a patient. The shell is made with a built-up support section to raise the shell above the general level of the bed, so that none of the perforations in the heel become blocked. In other words, the support section will facilitate a freer circulation of air about the heel of the patient, to effect a more rapid healing of heel sores. The liner has straps that project through slots in the shell and wrap about the foot and leg of the patient. This provides for the integral securement of both the liner and shell to the leg, while allowing the liner to be a separate element. A built-up ridge section in the heel portion of the shell prevents the heel of the patient from coming into contact with the shell. This will possibly prevent injury to the heel of the patient or the blocking of the perforations in the heel portion of the shell.

Boyd and Syme ankle amputations in children.

Abstract: The Syme and Boyd amputations at the ankle were compared in thirty-four children followed for three to sixteen years. Good results were found with both techniques. The best results occurred when the heel pad was aligned in the plantigrade position, which produced almost normal function of the heel pad. The Boyd technique was a surer method of obtaining such alignment but was technically more difficult. Both the Boyd and Syme techniques are recommended for ankle amputation in children, but a distinct advantage of one technique over the other could not be defined.

Methods and rationale for closed treatment of Achilles tendon ruptures

Abstract: Significant recent interest in closed treatment of Achilles tendon ruptures has been noted in the literature, as well as in clinical practice. This interest has grown out of dissatisfaction with operative treatment and its attendant high complication rates.The method of closed treatment consists of a gravity equinus, long leg, slightly bent knee cast for 6 weeks. This is followed by a short leg cast for a period of 4 weeks. A 2-cm heel lift is then used. Closed approximation of the tendon is easily demonstrated at the time of equinus casting. Results obtained have been gratifying.Observations were made on the Achilles tendon in dissected, fresh amputated specimens. Prominent transverse vessels in the paratenon, continuous with those of the anterior mesentery, illustrate well reports of the important role of these vessels in circulation to the midportion of the tendon, and its paratenon sheath is well demonstrated.An experimental study to document and compare closed methods of treatment of Achilles tendon ...

Device for use in evaluating the lower leg and foot

Abstract: A device for use in making biomechanical or orthopedic evaluations of the lower leg and foot employs a heel stationing arrangement to automatically provide a reference line parallel to the vertical bisection of the calcaneus bone. A forefoot measuring device is utilized to measure the angular deformity of the forefoot (varus or valgus) by determining the angular deviation of the plane of the ball of the foot with respect to a plane perpendicular to the heel reference line. The forefoot measuring arrangement is adaptable to measure either the plane of the ball of the foot as determined by all five rays or as determined by any desired grouping of rays, such as the second through the fifth rays. A rearfoot measuring arrangement measures the angular deformity of the rearfoot (varus or valgus) by determining the vertical bisection of the lower leg with respect to the heel reference line. Further, the device has an attachment to measure the dorsiflexion and plantarflexion of the foot about the ankle.

Adjustable release heel ski binding

Abstract: A heel ski boot binding for mounting onto a conventional snow ski is adapted to receive and releasibly maintain the heel of a conventional ski boot during normal skiing operations and to release the boot heel upon application of a predetermined vertical, lateral or torque force through the heel against the heel binding. The heel binding incorporates a biased clamp member that is compressed into a locked attitude against a top edge of the ski boot heel but can be released upon application of a predetermined vertical or torque force. The heel binding also incorporates one or more adjustable biased roller members adapted to be urged against the ski boot heel to secure the heel in position against the ski. The roller members release the ski boot when a predetermined lateral or rotational force is applied through the boot heel to the roller members. The biasing means of the roller members and clamp members are manually adjustable to set the amount of force necessary to overcome the bias and release the ski boot.

Ski boot heel restraining apparatus

Abstract: An improvement for cross country ski bindings comprising apparatus for preventing lateral motion of the heel of a cross country ski boot with respect to the ski when the heel is lowered into close proximity with the surface of the ski. The apparatus may comprise 2 pivotal vertical members between which the heel of the boot fits, the vertical members being, in accordance with one aspect of the disclosure, biased apart from each other so that the heel enters freely therebetween, the weight of the skier then, applied to the heel of the boot, causing the vertical members to move closer together to grip the heel of the boot. Thus the heel is firmly held in a central location on the ski. When it is desired to raise the heel of the boot, the vertical members are biased outwardly to release the heel. In accordance with another aspect of the disclosure the vertical members are rigidly communicated with the top surface of the ski, being widely enough disposed so that the heel of the boot fits loosely therebetween. With this aspect of the disclosure lateral movement of the heel is essentially restrained and the heel may be raised from the ski without impediment thereto. The disclosed apparatus thus provide for use of cross country skis with greater efficiency and facility, especially for the novice or beginning skier. Further, the ski incorporating the present invention may be used under a variety of snow and grade conditions without manual adjustment or manual attachment and detachment of the heel to the ski.

Peroneus longus tendon lengthening as an adjuvant measure in cavus foot surgery.

Abstract: Lengthening of the peroneus longus tendon is very important when performing cavus foot surgery. This tendon directly affects all three components (varus heel, increased arch height, and forefoot adduction) of the idiopathic cavus foot which can be accounted for by increased strength and activity of the peroneus muscle. The deforming force is removed or weakened according to the degree, duration and rigidity of the cavus foot by lengthening or transferring the tendon.

The split-heel technique in the management of calcaneal osteomyelitis in children. Report of three cases.

Abstract: Three cases are reported in which the split-heel technique was successfully used in the management of calcaneal osteomyelitis in children. Antibiotic therapy and debridement when necessary through medial or lateral incisions will usually eradicate the infection. Gaenslen's technique is recommended for refractory cases or patients with a draining sinus centrally located on the plantar aspect of the heel. An excellent functional result can be obtained. In general, excision of the calcaneus for chronic osteomyelitis in children is not necessary.
