Background The low-profile dorsal locking plating (DLP) technique is useful for treating dorsally comminuted intra-articular distal radius fractures; however, due to the complications associated with DLP, the technique is not widely used. Methods A retrospective review of 24 consecutive cases treated with DLP were done. Results All cases were classified into two types by surgical strategy according to the fracture pattern. In type 1, there is a volar fracture line distal to the watershed line in the dorsally displaced fragment, and this type is treated by H-framed DLP...

Ryosuke Sato, Naohito Hibino, Yoshitaka Hamada, Koichi Sairyo
Traumatic lunate fractures are very rare and those treatments require an understanding of anatomical features. We present a case of an ulnolunate ligament avulsion fracture of the lunate that was successfully repaired by surgical fixation with open reduction and internal fixation. We believe that restoration of ulnolunate ligament function is important to prevent further deterioration of wrist function after this injury.

Mohamed Noureldin, Sanjeev Kakar
Background Ulnar shortening osteotomy (USO) is a well-established procedure for the treatment of ulnar impaction syndrome. Although uncommon, the procedure can be associated with complications including nonunion, malunion, and hardware irritation. Case Description We present a 56-year-old woman who developed extensor carpi ulnaris (ECU) tendon instability following an USO. Literature Review The etiology of such a complication can be multifactorial. Clinical Relevance The recurrence of ulnar pain following an USO should raise the suspicion of possible ECU instability within the differential diagnosis...

Background The Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire is the most commonly used instrument to assess outcomes of basal joint arthritis (BJA). However, the DASH is subject to influence by the entire upper extremity. Purpose This study aims to develop and validate a disease-specific questionnaire for BJA that would be more sensitive to changes in thumb function and pain, and correlate better with objective and subjective metrics. Patients and Methods The thumb disability examination (TDX) was developed and 80 patients presenting with BJA at one of the two hospital-based hand clinics were enrolled in the validation study...

Background Flexion and extension of the wrist is achieved primarily at the radiocarpal and midcarpal joints. Carpal kinematics have been investigated, although there remains no consensus regarding the relative contribution of each bone to wrist motion. Purpose To determine the kinematics of the scaphoid, lunate, and capitate during unconstrained simulated wrist flexion/extension and to examine the effect of motion direction on the contribution of each bone. Materials and Methods Seven cadaveric upper extremities were tested in a passive wrist simulator with 10N tone loads applied to the wrist flexors/extensors...

Background Distal radius fractures are very common and an increased incidence of 50% is estimated by 2030. Therefore, both operative and postsurgical treatment remains pertinent. Main aim in treating intra-articular fractures is to restore the articular surface by internal fixation and early mobilization (EM). Questions/Purposes The purpose of this study was to compare functional results between EM immediately after surgery and 5 weeks of immobilization (IM). Patients and Methods In a randomized prospective study, 30 patients with an isolated distal radius fracture were treated by open reduction and internal fixation using a single volar locking plate excluding bone graft...

Background Damage to the interosseous membrane (IOM) can alter load transmission between the radius and ulna and decrease their axial stability. Less is known about the effect of IOM sectioning on the transverse stability between the radius and ulna. Purpose The purpose of this study was to quantify the radioulnar gapping at the distal radioulnar joint (DRUJ) during forearm rotation when the IOM was experimentally sectioned while maintaining the integrity of the distal radioulnar ligaments. Methods In 12 fresh-frozen cadaver forearms tested in a combined wrist-forearm simulator, the increase in gap between the radius and ulna, at the level of the DRUJ, was determined during cyclic forearm rotation following IOM sectioning...

Background The purpose of this article was to review the anatomy, kinematics of the distal radioulnar joint (DRUJ), and to discuss definition, classification, and diagnosis of DRUJ instability. Methods A biomechanical perspective on physical examination of DRUJ ballottement test was documented. Physiological dynamic DRUJ translation and differences of the translation following sequential ligament sectioning and changes in different forearm and wrist positions were demonstrated. The clinical significance of each ligament's contribution to joint stability in specific wrist positions was addressed...

Francis Bonte, Christophe L Mathoulin
Purpose A proximal avulsion of the radiocarpal capsule (PARC) is a cause of persisting posttraumatic wrist pain. This lesion is often overlooked and left untreated during wrist arthroscopy. Materials and Methods A record review was performed on 13 patients with this lesion who underwent diagnostic wrist arthroscopy after failed conservative treatment. We retrospectively reviewed the results of an arthroscopic repair method in 13 patients. Results In 11 of the 13 consecutive cases the lesion was sutured using an arthroscopic dorsal capsule-ligamentous repair technique...

Background Complete dislocation of the distal radioulnar joint (DRUJ) is a rare injury. Dislocation can present as uni- or multidirectional, acute or chronic, reducible or irreducible. It can occur due to isolated loss of ligamentous restraints or more frequent in Galeazzi - or Essex-Lopresti-type fractures. Case Description A 28-year-old man sustained a distal radius fracture and presented after conservative treatment with blocked supination. Examination revealed a malunion of the distal radius in combination with an irreducible dorsal dislocation of the DRUJ...

Musculoskeletal system is involved in about 20% of the patients diagnosed with tuberculosis. Although musculoskeletal tuberculosis generally affects spine and large joints (hip and knee), hand involvement of the tuberculosis is seen in 10% of the patients with musculoskeletal involvement and also isolated tuberculosis of hand or wrist is much rarer. In the following report, we discuss the case of a 23-year-old male patient who was diagnosed with isolated tuberculosis of the capitate and triquetrum bone. The patient presented with a nonhealing sinus on the left wrist joint...

Background Proximal row carpectomy (PRC) is contraindicated in wrists with preexisting arthritis of the proximal capitate or radiolunate fossa. Patients with these conditions frequently pursue wrist arthrodesis with its associated functional limitations. Questions/Purposes The purpose of this study was to evaluate the results of using lateral meniscal allograft interposition (LMAI), in combination with PRC, in patients with symptomatic wrist arthritis. The primary question is whether this allograft will allow wrist function comparable to that in patients having only a PRC...
