The aim of the present cadaveric study was to assess resistance to first metacarpal subsidence of three techniques of suspensionplasty after trapeziectomy. In total, 18 forearms (mean age 60 years [range 20-89]) were used with six specimens per surgical technique: palmar oblique ligament reconstruction with tendon interposition (LRTI), abductor pollicis longus (APL) suspensionplasty, or suture suspensionplasty. There was no significant difference in mean trapezial space height after trapeziectomy and suspensionplasty compared to the preoperative trapezial height. However, after simulation of physiological lateral pinch, there was a significant (p < 0.05) difference in mean trapezial space height between the APL suspensionplasty and the suture suspensionplasty compared to the LRTI group. After axial loading, there was significantly greater metacarpal subsidence in the LRTI group compared to the APL and suture suspensionplasty groups but no statistically significant difference between the suture suspensionplasty and the APL suspensionplasty groups.Level of evidence: V.

Madelung deformity remains a fascinating yet unresolved challenge. There is an increasing awareness for early diagnosis by healthcare providers with improvement in diagnostic modalities, however, the exact mechanisms for the development of the deformity have still to be clarified. While some corrective procedures have been described to effectively address an established deformity, the existing literature lacks clear and evidence-based treatment guidelines on how to proceed in daily practice. This review article aims to summarize the current best evidence on this topic, including particular areas of controversy and areas with need for future research.

Radial longitudinal deficiency (RLD) is commonly associated with thumb hypoplasia. The association between RLD and radial polydactyly (RP) is uncommon, but case reports or case series have been reported. We report our experience of managing patients with this association. A total of 97 patients with RLD were seen in our department, of which six were children with concomitant RLD and RP. Four children had both RLD and RP in the same limb; of them, three also had RLD in the contralateral limb. The mean age at presentation was 11.6 months. Awareness of this association alerts the clinician to look for RLD in the presence of RP and vice versa. This case series supports recent experimental and clinical evidence that RP and RLD may be part of the same developmental spectrum. Further studies may guide its inclusion as a possible new category in the Oberg-Manske-Tonkin (OMT) classification of congenital upper-limb anomalies.Level of evidence: IV.

We report a case of task-specific dystonia characterized by involuntary flexion of the ring finger. After resecting the flexor of the ring finger, the flexor digitorum profundus of the middle finger was transferred to the resected site.

We developed a classification for open hand fractures based on risk score to predict the risk of infection requiring re-debridement. A total of 846 retrospectively included patients underwent multivariable analysis with backward elimination to derive the predictive risk score from independent predictors. The incidence of infection requiring re-debridement was 4%. Independent predictors include diabetes mellitus or immunocompromised condition, injuries from a bite, fractures with comminution/bone loss, neurovascular injuries and inadequate soft tissue coverage. The area under the receiver operating characteristic curve of the prediction score was 0.79. The new classification system for open hand fractures divides patients into three groups: low-risk open fractures (Type I, score <1); moderate-risk open fractures (Type II, score 1 to 2.5); and high-risk open fractures (Type III, score >2.5), based on the risk of infection requiring re-debridement. Re-debridement and delayed primary closure are suggested for type III open fractures.Level of evidence: III.

We proposed a modification of the Rotterdam classification for thumb triplication and tetraplication. Twenty-one patients were included (24 cases of thumb triplication and four cases of tetraplication). These were analysed and classified according to a modification of the Rotterdam classification involving three steps; from the radial to ulnar side, we first identified each thumb on radiographs and gross appearance to divide into triplication or tetraplication. Second, we define the levels of duplication and established the nomenclature. Third, the aberrant features and their location were assigned for each thumb, again from radial to ulnar side. A surgical algorithm was also proposed. This modified classification may be helpful for characterizing the rare conditions of thumb triplication and tetraplication for use in patient and management and communication between surgeons.Level of evidence: III.

We systematically reviewed current measurement methods and the imaging modality of choice for intra-articular distal radial fractures. There is no current reference standard measurement method and a lack of evidence comparing them. Radiographs underestimate displacement, with most papers favouring CT.
