Avulsion of the Flexor Digitorum Profundus Tendon During the Curettage of a Recurrent Enchondroma: A Case Report.

Enchondroma rarely occurs in the distal phalanx, and avulsion of the flexor digitorum profundus (FDP) tendon in this area is also rare. We report a case of recurrent enchondroma in the distal phalanx, which required reconstruction for an accidental FDP avulsion during surgery. A 36-year-old right-handed woman visited our hospital with a suspected recurrence of enchondroma and a planned surgery.

Computed Tomography Investigation of First Metacarpal Subsidence After Suture Button Suspensionplasty: A Report of Two Cases.

First metacarpal subsidence often occurs after suture button suspensionplasty (SBS) for first carpometacarpal joint arthritis. In this study, we describe computed tomography (CT) findings in two cases of first metacarpal subsidence after SBS. Case 1 was a 51-year-old right-handed male.

Rare Case of Open Comminuted Scaphoid Fracture Dislocation: Treatment With Free Bone Graft and Locking Plate.

To the best of our knowledge, there are no reports in the literature of an open comminuted scaphoid fracture dislocation. We present such a rare case. The case report illustrates the case of a 58-year-old right-handed press operator who injured his left wrist when his hand got caught in a press machine.

Intraosseous Ganglion Spanning the Scaphoid and Lunate: A Case Report.

Intraosseous ganglions (IOGs) are actually quite common but one spanning two adjacent carpal bones is uncommon. We report a case with an IOG spanning the scaphoid and lunate, which was treated surgically. A 16-year-old right-handed female noticed left wrist pain that started spontaneously five years previously.

Rupture of Extensor Pollicis Longus Tendon Caused by Scaphoid Nonunion Advanced Collapse Wrist.

We report the case of a 69-year-old male patient with extensor pollicis longus (EPL) tendon rupture associated with a scaphoid nonunion advanced collapse (SNAC) wrist. He could not actively extend the left thumb interphalangeal joint and visited our institution for an examination. Plain X-rays revealed advanced stage SNAC and an enlarged soft tissue shadow owing to dorsal ridge growth.

A Loop-Wiring Technique for Volarly Displaced Distal Radius Fractures With Small Thin Volar Marginal Fragments.

Volarly displaced distal radius fractures (VD-DRFs) with small thin volar marginal fragments (VMFs) are challenging to treat with conventional volar locking plates (VLPs) alone. Several alternative surgical options have been reported to treat these fractures, including wire-loop fixation, spring-wire fixation, hook plates, headless compression screws, and tension-band wiring, but the optimal method is yet to be determined. We have devised a surgical treatment for these fractures, entitled the "loop-wiring method" in which VMFs are anatomically reduced and 2 0.

Adolescent talus body fracture with high displacement: A case report.

Rationale: Talus fracture is relatively rare in adults. Furthermore, talus fracture in pediatric population is rarer than in adult population. Although undisplaced talus fractures can be treated conservatively, most of talus fractures with displacement require surgical treatment in both pediatric and adult patients.

Bone Resection for Isolated Ulnar Head Fracture.

Distal ulnar fractures often occur with distal radius fractures (DRFs), and ulnar styloid fractures commonly occur in the setting of DRF. However, isolated ulnar head fractures are rare. We report a case of isolated ulnar head fracture in which we performed bone resection because the ulnar head bone fragment fractured when internal screw fixation was attempted.

A new variable angled locking volar plate system for Colles' fracture: outcome study and time-course improvement of objective clinical variables.

Our purposes were to report the radiographic outcomes and complications of patients with Colles' fracture treated with the Nakashima locking volar plate system (variable angled distal screw locking mechanism) prospectively and to report the results of objective clinical variables such as grip strength and range of motion of the wrist prospectively at up to one year. This study consisted of eight men and 32 women for analysis of radiographic parameters (volar tilt, radial inclination and radial length) and complications. Radiographic parameters were measured pre-operatively, immediately post-operatively and at final follow-up visit.

Temporary scaphotrapezoidal joint fixation for adolescent Kienböck's disease.

Purpose: There are few therapeutic guidelines for adolescent Kienböck's disease. The purpose of our study was to investigate the clinical and radiographic outcomes of temporary scaphotrapezoidal (ST) joint fixation for adolescent Kienböck's disease.

Methods: This was a retrospective review of 6 adolescent patients with Kienböck's disease treated by temporary ST joint fixation.

Is ulnar variance suitable for a parameter of Colles' fracture pre-operatively?

Background: To evaluate ulnar variance (UV) as a parameter for Colles' fracture as a measure of the true length of the distal radius pre-operatively, we measured UV pre-operatively in 20 patients with Colles' fractures being treated surgically using the method of perpendiculars. Because the distal fragment is by definition dorsi-flexed, the dorsal edge of the most distal part of the radius is seen proximally and the volar edge of it is seen distally on true postero-anterior x-ray of the wrist.

Methods: We measured three different UVs in x-rays.

Modified Sauve-Kapandji procedure for disorders of the distal radioulnar joint in patients with rheumatoid arthritis. Surgical technique.

Background: The Sauvé-Kapandji procedure has become popular for the treatment of disorders of the distal radioulnar joint in patients with rheumatoid arthritis, but this procedure is impossible to perform in patients with poor bone quality in the distal part of the ulna. We have modified the procedure for patients with poor bone quality in the distal part of the ulna. The modified procedure involves resecting the distal part of the ulna, making a drill-hole in the ulnar cortex of the distal part of the radius, rotating the resected portion of the ulna 90 degrees, inserting it into the distal part of the radius, and fixing it at that site with use of an AO cancellous-bone screw.

Treatment of enchondroma of the hand with injectable calcium phosphate bone cement.

Purpose: To report the results of treatment of enchondroma of the hand managed by curettage and calcium phosphate bone cement (CPC) grafting.

Methods: Ten patients with digital enchondroma were reviewed. There were 6 proximal phalanges, 2 middle phalanges, and 2 metacarpal bones.

Scaphotrapeziotrapezoid arthrodesis for the treatment of Lichtman stage 3B Kienböck disease.

We evaluated the results clinically and radiologically of 10 cases of Lichtman stage 3B Kienböck disease treated by scaphotrapeziotrapezoid (STT) arthrodesis alone. We retrospectively reviewed pain, range of movement, grip strength, and physical examination of the wrist as well as subjective satisfaction. We measured carpal height ratio and radioscaphoid angle.

Modified Sauvé-Kapandji procedure for disorders of the distal radioulnar joint in patients with rheumatoid arthritis.

Background: The Sauvé-Kapandji procedure has become popular for the treatment of disorders of the distal radioulnar joint in patients with rheumatoid arthritis, but this procedure is impossible to perform in patients with poor bone quality in the distal part of the ulna. We have modified the procedure for patients with poor bone quality in the distal part of the ulna. The modified procedure involves resecting the distal part of the ulna, making a drill-hole in the ulnar cortex of the distal part of the radius, rotating the resected portion of the ulna 90 degrees , inserting it into the distal part of the radius, and fixing it at that site with use of an AO cancellous-bone screw.

Early corrective osteotomy for a malunited Colles' fracture using volar approach and calcium phosphate bone cement: a case report.

We report a case of malunion of the distal radius after a Colles' fracture treated with osteotomy using a volar approach combined with calcium phosphate bone cement grafting of the dorsal defect via a drill hole from the volar cortex 6 weeks after the injury. One year and 4 months after surgery range of motion and grip strength were improved and x-rays of the wrist showed complete union of the distal radius with progressive absorption of the calcium phosphate bone cement.

Isolated rupture of radial collateral ligament of the small finger dip joint repaired with a bone suture anchor: a case report.

Isolated rupture of radial collateral ligament of the small finger DIP joint is a rare injury. We treated this lesion using a bone suture anchor with excellent results.

Dorsal wrist syndrome repair.

Dorsal wrist pain with or without a palpable dorsal wrist ganglion is a common complaint. Watson developed the concept of the dorsal wrist syndrome (DWS) which is an entity encompassing pre-dynamic rotary subluxation of the scaphoid and the overloaded wrist. We reviewed 20 cases of DWS treated surgically.

Enchondroma protuberans of the phalanx: a case report.

Enchondroma protuberans, which is defined as an exophytic enchondroma of a long bone, is a rare condition. There have been 6 previously reported cases with only 1 case occurring in the hand. We report a case of an enchondroma protuberans of the ring finger middle phalanx treated by marginal excision of the soft-tissue component, intramedullary curettage, and placement of calcium phosphate cement.

Duplicate extensor tendons of the thumb mimicking rupture of the extensor pollicis longus tendon.

We report a patient with duplicate extensor pollicis longus tendons, who complained of inability to extend the thumb fully because of impingement of the musculotendinous junction of the duplicate tendons. Extension of the thumb recovered completely after Lister's tubercle was excised and the extensor retinaculum was released. Selective windowing with highlighting of the soft tissue in the axial T1-weighted magnetic resonance image at the level of the distal radioulnar joint showed two tendons in the third extensor compartment.

Rotational radioulnar dissociation: a case report and review of the literature.

We report a rare case of radioulnar dissociation in an 11-year-old boy associated with fracture of the medial humeral epicondyle. Open reduction and Kirschner wire fixation was performed for the epicondylar fracture. The radial head was reduced closed, and the distal radioulnar joint reduced spontaneously.

Technique of intramedullary fixation for arthrodesis of the wrist in rheumatoid arthritis.

We did 18 arthrodeses of the wrist in 16 patients with rheumatoid arthritis using an intramedullary fixation technique. There were 15 women and one man, whose ages at operation ranged from 47 to 71 years (mean 58). Follow up ranged from 13 to 68 months (mean 27).

Radiographic changes after resection of the distal ulna in patients with rheumatoid arthritis.

Radiographic changes in the wrist after resection of the distal ulna in 61 rheumatoid patients (63 wrists) were evaluated more than five years after operation. The wrists were classified on preoperative radiographs into stable or unstable forms as defined by Simmen and Huber. Of 63 wrists, 52 were classified as stable and the remaining 11 were classified as unstable.
