Metacarpal Stress Fracture Is Not an Uncommon Condition in Adolescent Racket Athletes.

Background: Stress fractures of the metacarpal bones are considered uncommon. We report on 11 adolescent athletes with these stress fractures, successfully treated with cessation of sports activities. .

Low-grade fibromyxoid sarcoma arising in the big toe.

Low-grade fibromyxoid sarcoma (LGFMS) is a rare tumor. Reported herein is a case of LGFMS arising in the big toe. The patient was a 58-year-old man who underwent excision of the tumor.

Muscle atrophy after treatment with Halovest.

Study Design: A prospective study was conducted on the sequential changes in the muscles around the cervical spine following external fixation for an extended period.

Objective: Muscular atrophy around the cervical spine following prolonged external fixation with a Halovest and subsequent recovery from the atrophy were examined.

Summary Of Background Data: There are a number of reports on the usefulness of the Halovest.

Long-term follow-up of a malunited, isolated fracture of the capitate in a 6-year-old boy.

A 6-year-old boy with an isolated fracture of the capitate was presented. First radiograghs at our clinic revealed an oblique fracture with a displacement of 5 mm on the lateral view, which we successfully treated with immobilization. When complete union was recognized in the radiographs, the capitate had a deformity consisting of a large prominence on the palmar aspect.

Arthroscopically assisted treatment of ankle fractures: arthroscopic findings and surgical outcomes.

Purpose: Malleolar fractures have been reported to be associated with a poor prognosis even when the anatomic reduction is complete. Soft tissue injuries such as damage to the cartilage and ligaments, soft tissue impingement, and the existence of free bodies within the intra-articular space account for this poor outcome. In treating fresh malleolar fractures, an arthroscope is used at our institution to confirm anatomic reduction on the articular surface and treat intra-articular injuries.

Arthroscopic treatment of a ganglion of the first metatarsophalangeal joint.

The case of a ganglion that had developed around the first metatarsophalangeal (MTP) joint and in which several other therapeutic approaches were unsuccessful was treated using an arthroscopic assisted procedure. During MTP arthroscopy, we found that the pedicle of the tumor was attached to the interior of the joint, and the lesion was successfully extirpated. Communication with the cyst was found on the medial side of the lateral sesamoid bone, which coincided with the rounded portion of the first MTP joint at the sole, where stress is exerted repeatedly while walking.

Endoscopic treatment of delayed unions and nonunions with calcium phosphate paste.

We describe a new therapeutic procedure using a bone filler in a calcium phosphate paste (bone paste) for endoscopic surgery for delayed unions and nonunions. Guided by radiography, the site of nonunion was confirmed. Two portals were created toward the nonunion site and, through each portal, the tissue around the nonunion site was released.

Osteosynthesis for nonunion of the lateral humeral condyle.

The treatment of established nonunion of the lateral humeral condyle is controversial. Twenty patients who had osteosynthesis of the nonunion were evaluated to clarify the changes in range of motion and the factors influencing those changes. The average age of the patients at surgery was 13.

Anatomical study of the carpal attachment of the triangular fibrocartilage complex.

There have been few descriptions of the site of attachment onto the triquetrum, the so-called meniscal homologue, of the triangular fibrocartilage complex (TFCC). We have investigated the sites of attachment onto the triquetrum of 87 TFCCs collected from embalmed cadavers. All TFCCs were smoothly attached to the triquetrum.

Complications of vascularized fibula graft for reconstruction of long bones.

The clinical results and complications of the vascularized fibular graft for the reconstruction of various long bone defects were reviewed in 60 cases. Bony reconstruction was achieved in 57 of the 60 cases; however, various postoperative complications occurred in 54 percent of the cases. One case of arterial thrombosis of an anastomosed vessel and nine cases of venous congestion of the monitoring flap occurred in the early postoperative periods.

Long-standing nonunion of fractures of the lateral humeral condyle.

Background: Patients with nonunion of a fracture of the lateral humeral condyle often have pain, instability, or progressive cubitus valgus deformity with tardy ulnar nerve palsy. However, some patients have minimal or no symptoms or disabilities. We evaluated patients with long-standing established nonunion of the lateral humeral condyle to correlate the clinical long-term outcome of this condition with the original fracture type.
