Modified Wassel-Flatt Type III Radial Polydactyly: Subtypes and Their Outcomes.

Purpose: We aimed to subdivide modified type III radial polydactyly and evaluate the applied surgical procedures and outcomes according to the subtypes.

Methods: This study included 32 thumbs of 32 patients treated for modified Wassel-Flatt type III radial polydactyly from March 2008 to December 2018. Each patient was subclassified into parallel, divergent, and convergent types according to the alignment of the duplicated digit.

Reoperation after primary operation for pre-axial polydactyly of the hand: A 12-year experience at a single institute.

Background: This study aimed to evaluate and describe the rate, reasons, and detailed procedures of reoperations for pre-axial polydactyly of the hand at our institute conducted within 12 years.

Methods: We retrospectively reviewed the medical records and radiographs of 268 patients (292 digits) with pre-axial polydactyly of the hand, who were treated surgically at our institute from November 2006 to May 2018 and followed up for >12 months.

Results: Fifty-two thumbs of 47 patients underwent reoperations, yielding a 17.

Surgical Results of Ulnar Component Excision and Radial Component Reconstruction in Patients With Preaxial Polydactyly of the Hand.

Purpose: Resection of the underdeveloped digit and reconstruction of the robust digit is the standard treatment option for preaxial polydactyly of the hand. As an underdeveloped digit, the radial component is usually excised, whereas the ulnar component excision is rarely needed. This study aimed to evaluate the surgical results of ulnar component excision and radial component reconstruction in patients with preaxial polydactyly of the hand.

Excision of Rudimentary Preaxial Polydactyly of the Hand with Use of Electrocautery.

Background: Suture ligation has been used widely for the treatment of rudimentary type extra digits, but several complications related to this treatment have been reported. The purpose of this study was to describe a new technique for excision of rudimentary preaxial polydactyly of the hand using electrocautery and assess its clinical outcomes.

Methods: The authors performed a retrospective study of 34 thumbs (32 patients) that had undergone excision of rudimentary preaxial polydactyly using electrocautery under local anesthesia.

Pronator quadratus pedicled bone graft in the treatment of Kienböck disease: follow-up 2 to 12 years.

We inserted a pronator quadratus pedicled bone graft into the avascular lunate with preservation of its corticocartilaginous portion for the treatment of Kienböck disease. Twenty-seven patients (14 men, 13 women; mean age, 42 years (range 17-66 years)) were treated between September 2005 and July 2014 and followed up from 2 to 12 years. Three patients had Lichtman stage II disease, 13 had stage IIIA, and 11 had stage IIIB.

Comparison of Long-Term Outcomes of Radial Osteotomy and Nonoperative Treatment for Kienböck Disease: A Systematic Review.

Background: Radial osteotomy has shown favorable clinical results for early to advanced stages of Kienböck disease. However, it is not clear whether this technique could change the natural course of the disease, or whether its clinical results are actually superior to those of nonoperative treatment. The purpose of this study was to compare radial osteotomy with nonoperative treatment in terms of long-term radiographic and clinical outcomes in patients with Kienböck disease.

Psychological Status Is Associated With Symptom Severity in Patients With Carpal Tunnel Syndrome.

Purpose: The purpose of this study was to investigate whether psychological status is associated with symptom severity or functional disability of carpal tunnel syndrome (CTS) patients.

Patients And Methods: Sixty patients diagnosed with CTS and treated with carpal tunnel release (CTR) were asked to complete a self-administered questionnaire consisting of 3 validated measures obtained before and 3 months after surgery. The Boston Carpal Tunnel Questionnaire (BCTQ) was administered to assess symptoms (BCTQ-S) and functional disabilities (BCTQ-F), and the Center for Epidemiologic Studies Depression Scale (CES-D) and Pain Anxiety Symptoms Scale (PASS) were administered to assess depression and pain anxiety.

Comparison of outcomes between partially healed and acute metaphyseally malaligned distal radial fracture treated by palmar locking plate fixation.

Background: The purpose of this study was to determine whether a partially healed (surgical delay of 2-6 weeks) metaphyseally malaligned distal radius fracture (DRF) treated using the extended palmar approach with palmar locking plate fixation has poorer clinical or radiological outcomes than those of acute (surgical delay of ≤2 weeks) metaphyseally unstable DRF treated by palmar locking plate fixation.

Methods: We identified 24 patients (Group A) who were treated with palmar locking plate for a partially healed (surgical delay of 2-6 weeks) metaphyseally malaligned DRF. We selected 48 patients (Group B) who were treated with palmar locking plate among the acute (surgical delay of ≤2 weeks) metaphyseally unstable DRF to be individually matched in a 1:2 ratio for sex, age, and fracture type.

The Outcomes of Extension Block Pinning and Nonsurgical Management for Mallet Fracture.

Purpose: We aimed to compare the clinical and radiographic results of patients with a mallet fracture involving more than one-third of the articular surface, but without a high degree of distal interphalangeal (DIP) joint subluxation, treated with extension block pinning or nonsurgical management.

Methods: Forty-nine patients with a mallet fracture involving more than one-third of the articular surface were reviewed. Twenty-six cases were treated using extension block pinning (surgery group) and 23 were treated nonsurgically (nonsurgical group).

Bone Mineral Density and Prevalence of Osteoporosis in Postmenopausal Korean Women with Low-Energy Distal Radius Fractures.

The aim of this study was to evaluate the bone mineral density and the prevalence of osteoporosis in postmenopausal Korean women with low-energy distal radius fractures and compared with those of aged-matched normal Korean women. Two hundred and six patients with distal radius fractures between March 2006 and March 2010 were included in this study. Patients were divided into three groups by age; group 1 (50-59 years), group 2 (60-69 years), and group 3 (70-79 years).

Reliability of semi-pronated ulnar deviation PA view (billiard view) of the wrist in evaluating the scaphoid.

Various methods assessing the scaphoid have been reported because of its unique position. In our hospital, pre- and postoperative evaluation of the scaphoid alignment has been carried out in the billiard view, a combination of 45° pronated oblique with ulnar deviation posteroanterior (PA) view, in addition to 3DCT scan and PA and lateral view. This study compared the intra- and inter-observer reliabilities of the lateral intrascaphoid angle and scaphoid length (SL) and scaphoid height (SH) on the billiard view.

Double tension band wiring for treatment of olecranon fractures.

Purpose: Although tension band wiring (TBW) is generally accepted as standard treatment for olecranon fractures, it has several shortcomings such as loss of reduction, skin irritation, and migration of the K-wires. To overcome these problems and increase fixation stability, we used a rigid fixation technique with double tension band wiring (DTBW). Here, we describe the technique and outcomes of the treatment.

Musicians' medicine: musculoskeletal problems in string players.

There is increasing attention to medical problems of musicians. Many studies find a high prevalence of work-related musculoskeletal disorders in musicians, ranging from 73.4% to 87.

Reconstruction of the shoulder region using a pedicled latissimus dorsi flap after resection of soft tissue due to sarcoma.

Six patients underwent reconstruction of soft tissue using a pedicled latissimus dorsi flap after tumour resection of the shoulder region. Successful flap healing was observed in all patients. One flap exhibited partial skin necrosis, which healed after conservative treatment.

Classification of postaxial polydactyly of the foot.

Background: The origins and shapes of accessory digits in postaxial polydactyly of the foot were analyzed morphologically and radiographically, and their characteristics were determined. A simple classification method was then devised to assist in determining the most appropriate treatment options.

Methods: We evaluated 113 feet of 95 patients who had surgery for the treatment of postaxial polydactyly between 1998 and 2002.
