The long accessory flexor muscle: an anatomical study.

A total of 136 lower limbs from 68 human cadavers were dissected to determine the incidence of the long accessory flexor muscle and its origins and insertions. The muscle was present in 11 of 136 lower extremities (8%) and 9 of 68 cadavers (13%). Five long accessory flexor muscles originated from the tibia and fascia of the deep posterior compartment and six began on the fibula. All of the tendons were deep to the laciniate ligament and coursed within the tarsal tunnel. All five of the tendons originating from the tibia inserted on the quadratus plantae, with two of the tendons having an additional insertion on the flexor digitorum longus. Three of the tendons with fibular origin inserted on the quadratus plantae and three inserted on the flexor digitorum longus. The importance of the long accessory flexor muscle relates as a cause or association with tarsal tunnel.

Bilateral accessory soleus: a report on four patients with partial fasciectomy.

Four young adults (average age 24 years) presented with complaints of posterior ankle pain after running. Bilateral accessory soleus muscles were diagnosed using magnetic resonance imaging or CT scan. Symptoms were present an average of 3 years before diagnosis. Two patients had previous surgery (ankle arthroscopy, tarsal tunnel release, and leg compartment release) before diagnosis and treatment. Obliteration of Kager's triangle (posterior ankle fat pad) was present on six out of eight lateral ankle radiographs. Posteromedial prominence was present on four out of eight ankles. Operative exploration confirmed the presence of five muscles and fasciectomy was performed. Follow-up (17 to 29 months) showed good relief of symptoms in all patients and return to long-distance running for three patients. Dissection of 47 preserved cadavers revealed three accessory soleus muscles in the 94 extremities (two muscles were bilateral in one cadaver).

Excision of the fractured os peroneum: a report on five patients and review of the literature.

Five patients sustained fractures of the os peroneum after supination and plantarflexion injuries. Two of the injuries involved the knee in hyperflexion and the foot under the buttock. Four of the five were treated with immobilization for 6 weeks. All five required operative excision of the fractured sesamoid 8 months to 8 years after the initial injury. Three fractures were bipartite and there were two multipartite fractures. At 12- to 28-month follow-up, all patients were pain-free over the lateral midfoot and four patients returned to preinjury activity levels.

On-site facilities. LIFE FORCE's decision to build.

The size and cost of an on-site maintenance and operations facility will vary greatly depending on the size and location of the structure. The decision to build such a facility must involve an effective feasibility study to evaluate the actual needs and requirements of the air medical program in association with the budgetary constraints of the sponsoring hospital.

Reaction of the urinary tract to polypropylene sutures.

Cystotomies were performed on 99 mature guinea pigs and closed with polypropylene sutures. The bladders were removed at intervals from day 4 through day 144 postoperatively. They were studied with both light and electron microscopy. A localized mild, acute, inflammatory reaction was noted transitorily; it subsided between the 7th and 14th day. Three calculi were formed, a result which compares favorably with studies of other sutures. Results indicate that the suture may have a place in urologic surgery, but further studies are necessary before clinical use.

Epithelialization after cystotomy.

Cystotomies were performed on mature guinea pigs using aseptic technique, and one layer closure with polypropylene sutures. It was found that epithelialization over the suture material was completed by 3 days and that epithelialization of the bladder mucosa itself after a mucosa-mucosa approximation was completed within 4 days. The main significance of this investigation is that the normal bladder mucosa was completely healed within 4 days.
