Abstract Background Thumb duplication is one of common anomalies of the hand. Among of Wassel type IV subtypes, type IV-D duplication with a zigzag deformity is most challenging for reconstructing. Several factors may affect the surgical outcomes. This study aimed to present an opening wedge osteotomy at proximal phalangeal neck for treating type IV-D duplication. Methods Data from 14 patients are presented in this study. Eight patients had duplication of the right thumb, and six left thumb. After removal of radial supernumerary thumb, a snug collateral ligament was repaired to correct angular deformity of metacarpophalangeal joint (MCP). Angular deformity of the interphalangeal (IP) joint was corrected by an opening wedge osteotomy at the proximal phalangeal neck. A wedge bone from ablated thumb was grafted to correct the malalignment. IP joint was further stabilized by plication of the ulnar capsule. The relocation of radial part of FPL to the center of distal phalangeal base by use of pull-out suture technique Results After surgery, the angulations of the IP joints and the MCP joints were improved. Bone union was observed in all patients. According to the Japanese Society for Surgery of the Hand evaluation form, twelve cases were rated good, 2 cases fair. Stability of IP and MCP joints was good in all cases. The active ROM of IP was less in residual thumb than in normal thumb. Small nails were observed in some patients. Conclusions Although the reconstructed thumbs were smaller than normal counterparts, they were aligned and with stable joints. The opening wedge osteotomy at proximal phalangeal neck could improve realignment of IP joint and prevent reoccurrence of deformity over time.

Thumb Duplication

Five cases of Wassel types III, IV and VII thumb duplication underwent a Bilhaut-Cloquet procedure. A stable and mobile metacarpophalangeal joint was achieved in all cases. Interphalangeal joint motion was limited but this joint was stable in all cases. The nail ridge in these thumbs was minimal. A strong, stable thumb of normal size and good appearance can result from the Bilhaut-Cloquet procedure. When one nail is 70% of normal width, a modified procedure using the whole of one nail will avoid the nail ridge, but the nail will still differ from normal.

Stroke has been the leading cause of disability due to the induced spasticity in the upper extremity. The constant flexion of spastic fingers following stroke has not been well described. Accurate measurements for joint stiffness help clinicians have a better access to the level of impairment after stroke. Previously, we conducted a method for quantifying the passive finger joint stiffness based on the pressure-angle relationship between the spastic fingers and the soft-elastic composite actuator (SECA). However, it lacks a ground-truth to demonstrate the compatibility between the SECA-facilitated stiffness estimation and standard joint stiffness quantification procedure. In this study, we compare the passive metacarpophalangeal (MCP) joint stiffness measured using the SECA with the results from our designed standalone mechatronics device, which measures the passive metacarpophalangeal joint torque and angle during passive finger rotation. Results obtained from the fitting model that concludes the stiffness characteristic are further compared with the results obtained from SECA-Finger model, as well as the clinical score of Modified Ashworth Scale (MAS) for grading spasticity. These findings suggest the possibility of passive MCP joint stiffness quantification using the soft robotic actuator during the performance of different tasks in hand rehabilitation.

We developed a new internal fixation method for extra-articular fractures at the base of the proximal phalanx using a headless compression screw to achieve rigid fracture fixation through a relatively easy technique. With the metacarpophalangeal joint of the involved finger flexed, a smooth guide-pin is inserted into the intramedullary canal of the proximal phalanx through the metacarpal head and metacarpophalangeal joint. Insertion tunnels are made over the guide-pin using a cannulated drill. Then, a headless cannulated screw is placed into the proximal phalanx. All of five fractures treated by this procedure obtained satisfactory results.

Correction of unequal radial polydactyly in which neither thumb duplicates possess both well-developed proximal and distal components, remains challenging. Current techniques using on-top plasty techniques require circumferential incisions, often resulting in postoperative swelling and dorsal scars. We described our experience using a volar approach to achieve better aesthetic and functional results. Twenty-one patients underwent this surgery between 2008 and 2018, with a mean follow-up of 5.1 years. The mean flexion–extension arc for the metacarpophalangeal joint was 75° and that of the interphalangeal joint was 43°. Mean percentage of key, tripod and tip pinch strength were 77%, 79% and 77%, respectively, when compared with the contralateral side. The Vancouver Scar Scale showed an average score of 1.2. We conclude from our study that the volar approach to on-top plasty is a good technique for the correction of unequal radial polydactyly, with good functional and aesthetic results. Level of evidence: IV
