Knee braces.

The preceding discussion has profiled the three different types of knee braces which are available on today's market. It also has attempted to discuss the controversies surrounding these braces and to analyze the scientific data presented to date. Prophylactic braces have been shown to be ineffective in preventing knee injuries in its present day design. Evidence also has shown that their use may even lead to increased knee injuries. Rehabilitative braces, on the other hand, do serve a useful purpose in regard to the operative and non-operative treatment of ligamentous knee injuries. With their ease of application and control of joint motion, they are an important addition to the surgeon's armamentarium. One must keep in mind, however, that these braces provide little static anterior/posterior control and the hinge settings may not actually affect true joint motion. Functional knee braces may play a role in the treatment of patients with pathological laxity due to an injury of the anterior cruciate ligament. Combined with an adequate rehabilitation program and activity modification, these braces do limit excessive anterior tibial translation under low loading conditions. However, under conditions of high loading these braces provide little or no resistance to anterior translation. Therefore, in most sporting activities, their efficacy is questionable. Knee bracing continues to be a complex and controversial topic in the field of orthopedic surgery.(ABSTRACT TRUNCATED AT 250 WORDS)

Nonoperative treatment of stress fractures of the proximal shaft of the fifth metatarsal (Jones' fracture).

Early operative fixation of stress fractures of the proximal diaphysis of the fifth metatarsal has been advocated because of the high potential for delayed union, nonunion, and refracture. Case reports are given of three athletes with stress fractures of the proximal shaft of the fifth metatarsal who were treated nonoperatively and who returned to early athletic participation without recurrent symptoms or refracture. Treatment of this injury should be individualized because of the potential for nonunion and the ability of this fracture to heal.

Zone approach to knee arthroscopy.

The zone approach to knee arthroscopy divides the knee into ten anatomic zones. This article presents the zone classifications and describes the combination of portals for the arthroscope, the probe, and the operating instruments. The particular leg position which is thought to allow the best visualization of each zone is also described. Alternate portals are necessary in certain situations, as in knees with tight ligamentous structures. This list of standard and alternate portals is not meant to be all-inclusive, but we do urge that all ten zones are examined during arthroscopy. The objectives of this article are to describe a method of arthroscopic examination that is both systematic and comprehensive, and to develop an arthroscopic nomenclature that allows easy localization and reporting of pathology in the knee joint.

Arthroscopic evaluation of the injured athlete's knee.

In summary, arthroscopic evaluation of the athlete's knee joint provides a highly accurate means of diagnosing intra-articular lesions. It provides valuable information regarding treatment and prognosis. In addition, if arthroscopic surgical treatment is possible, even greater benefits in regard to more rapid return to full athletic activity will be possible.

Ankle arthroscopy. Technique and indications.

The technique and indications for ankle joint arthroscopy have been presented. The keys to successful ankle arthroscopy include (1) a knowledge of extra-articular anatomy, (2) a systematic approach to the evaluation of the various compartments arthroscopically, (3) constant joint distention, and (4) muscle relaxation so the joint can be easily manipulated and distracted.

Suprascapular neuropathy in the differential diagnosis of rotator cuff injuries.

Four cases of suprascapular neuropathy treated by nonoperative means have been presented. Complete recovery occurred in all four. The anatomy of the suprascapular nerve and probable mechanisms of injury secondary to traction have been discussed. The importance of electromyography in diagnosis has been stressed. Longer periods of nonoperative treatment are recommended here than by previous authors. Since the lesion is felt not to be an entrapment phenomenon but, rather, a traction injury, operative treatment should consist of release of the nerve at the notch to reduce the possibility of further traction injury, and a neurolysis should be done as well.

Metatarsal stress fractures.

We evaluated metatarsal lengths from roentgenograms in a group with metatarsal stress fractures and compared them with those of a control group having no foot symptoms to determine if a short first metatarsal could be implicated as a cause for metatarsal stress fractures. By statistical analysis we showed that the lengths of the first and second metatarsals in the group with stress fractures did not differ from those in a randomly selected control group. In addition, we determined that to be "short," the first metatarsal must be less than 73% of the length of the second metatarsal, and to be "long," the first metatarsal must be more than 94% of the length of the second metatarsal.

Cryotherapy and nerve palsy.

Ice application is one of the most extensively used treatments for athletic injuries. Frostbite is a recognized danger. Five cases of nerve palsy resulting from ice application are reported here. These palsies were temporary. They usually resolve spontaneously without any significant sequelae. This complication can be avoided by not using ice for more than 30 minutes and by guarding superficial nerves in the area.

Nonoperative treatment of double lateral ligament tears of the ankle.

In this article the objective evaluation of 39 cases of double lateral ligament tears of the ankle treated by cast immobilization is described. Such treatment resulted in a 79.5% success rate as determined by repeat stress roentgenograms. In addition, a statistical method which may aid the orthopaedist in deciding whether to use nonoperative or operative treatment is presented.

Operative treatment of posterior shoulder dislocations by posterior glenoidplasty, capsulorrhaphy, and infraspinatus advancement.

Posterior dislocations of the shoulder are rare, comprising only 4% of shoulder dislocations. Several operative procedures have been described in treating recurrent dislocations, and results have been varied. A retrospective review of eight shoulders in eight patients treated by posterior glenoidplasty with capsulorrhaphy and infraspinatus advancement revealed generally good results. Followup ranged from 10 to 114 months, with an average of 36 months. Seven patients were classified as recurrent traumatic dislocators and one as a recurrent atraumatic voluntary dislocator. Results graded as good, fair, and failure were based on pain, range of motion, return to activities, recurrence, and roentgenograms. Six patients had good results with return to full activity, full range of motion, no pain, no recurrence, and no degenerative changes of roentgenograms. One patient, who has not returned to athletic activities and has occasional pain and limited range of motion, was graded as a fair result. The patient classified as an atraumatic voluntary dislocator has occasional feelings of instability and slight pain with strenuous activity, but has not had a recurrence and has no difficulty with activities of daily living. She was also classified as a fair result. There have been no recurrences or degenerative changes on followup radiographs. Computerized tomography performed on two patients documented a definite change in orientation of the glenoid. We feel that glenoidplasty with capsular reefing and infraspinatus advancement, if performed carefully, provides an excellent operative treatment for recurrent posterior dislocations of the shoulder.

Instrumented testing of functional knee braces.

The ability of seven functional knee braces to control anterior tibial displacement in three severely lax ACL deficient knees using two instrumented testing devices was studied. Some braces were statistically shown to be much better in this regard than others, but not all data obtained was statistically significant. This material should aid one in determining which braces offer the greatest degree of control of anterior tibial displacement in patients with ACL insufficiency.
