BACKGROUND: There is little information regarding anatomic structures at risk during closed percutaneous treatment of fifth metacarpal neck fractures. This study evaluates a variety of common percutaneous techniques with the hypothesis that each approach presents unique risks to tendons and neurovascular structures. METHODS: Seven cadaveric hands were used for this study. The senior author, a board-certified hand surgeon with more than 20 years of experience, used a mini-C arm to pass 1...

BACKGROUND: The purpose of this study was to compare the mechanical properties of metacarpal neck fracture fixation by headless compression screw (HCS) with that of Kirschner wire (KW) cross-pinning and locking plate (LP) fixation. METHODS: A metacarpal neck fracture was created in 30 fourth-generation composite Sawbones metacarpal models. A volar-based wedge was removed using a custom jig to simulate a typical apex dorsal fracture, unstable in flexion. The models were divided into 3 equal groups based on the method of fixation: retrograde cross-pinning with two 1...

In remote wilderness environments, local people with traditional knowledge of medicinal plants are potentially important first-line health care providers. We present a case of a 31-year-old man who fell off a horse while trekking through a remote mountain landscape in Ethiopia and sustained blunt force trauma to the hand. A local mountain hut keeper examined the patient's hand and used heated leaves of the succulent plant Kalanchoe petitiana to treat a suspected metacarpal fracture. As first responder in a low-resource setting, the hut keeper relied on his traditional knowledge of ethnoveterinary medicine to improvise a treatment for a human injury in a remote mountain environment...

PURPOSE: The objective of this study was to analyze complications and patient-related functional outcome after antegrade intramedullary Kirschner-wire fixation of metacarpal shaft fractures. METHODS: All consecutive patients treated from January 2010 until December 2015 were retrospectively analyzed using patient logs and radiographic images. Indications for operative fixation were angulation > 40°, shortening > 2 mm, or rotational deficit. Complications were registered from the patient logs...

Injuries are common in ice hockey, a contact sport where players skate at high speeds on a sheet of ice and shoot a vulcanized rubber puck in excess of one hundred miles per hour. This article reviews the diagnoses and treatment of concussions, injuries to the cervical spine, and lower and upper extremities as they pertain to hockey players. Soft tissue injury of the shoulder, acromioclavicular joint separation, glenohumeral joint dislocation, clavicle fractures, metacarpal fractures, and olecranon bursitis are discussed in the upper-extremity section of the article...

We report a rare case of dislocation of second to fourth carpometacarpal (CMC) joints of the right hand with combined dorsal and ulnarward displacement of the second to fourth digits and fracture of the shaft of the first metacarpal associated with degloving injury. These injuries were diagnosed early and treated successfully with closed reduction and internal fixation using Kirschner wires. The functional outcome was good at follow-up at 5 years. A high index of suspicion is required to successfully diagnose and treat this condition...

PURPOSE: Surgeons confronted with a long spiral metacarpal fracture may choose to fix it solely with lagged screws. A biomechanical analysis of a metacarpal spiral fracture model was performed to determine whether 3 1.5-mm screws or 2 2.0-mm screws provided more stability during bending and torsional loading. METHODS: Second and third metacarpals were harvested from 12 matched pairs of fresh-frozen cadaveric hands and spiral fractures were created. One specimen from each matched pair was fixed with 2 2...

BACKGROUND: Distal ulna fractures at the ulnar neck can be seen in association with distal radius fractures, and multiple techniques have been described to address the ulnar neck component of these injuries. We have found that treatment of ulnar neck fractures can be challenging in terms of anatomy and fracture fixation. We present a new percutaneous fixation technique for ulnar neck fractures commonly seen with distal radius fractures. TECHNIQUE: Fixation of the ulnar neck fracture is performed after fixation of the distal radius fracture...

Association of fracture of trapezium with Bennett's fracture is very rare and makes reduction and stabilisation more difficult. We are reporting a rare case of Bennett's fracture with fracture of the trapezium and subluxation of the carpo-metacarpal joint (CMC) joint. The patient was a 47-year-old school teacher who fell from his motorbike on his outstretched right dominant hand. Radiographs and computed tomography showed fracture of the trapezium with subluxation of the CMC joint, associated with Bennett's fracture...

Fracture dislocations of the STT joint are extremely rare. We present the case of a 50-year-old worker, who sustained a crush injury of his left hand with a dorsal fracture dislocation of the trapezoid bone and the associated second metacarpal bone at the STT, and a concomitant compartment syndrome of the hand. The fracture was reduced immediately and compartment release was performed, followed by percutaneous stabilisation using three K-wires. Material removal after six weeks was followed by intensive physical therapy...

Metacarpal fractures comprise 18 to 44% of hand fractures. Fractures from the second to the fifth metacarpals are 88% of the metacarpal fractures and fractures of the fifth metacarpals are the most common. Fractures of the neck of the fifth metacarpal are about 20% of all the hand fractures. Most of these fractures can be treated conservatively with good functional results. However, for those neck and shaft unstable fractures that need surgical treatment, there is no gold standard for osteosynthesis. Recently, there have been reports of minimally invasive osteosynthesis using headless retrograde intramedullary cannulated screws with good functional results...

BACKGROUND: Palmar/plantar osteochondral disease (POD) and third metacarpal/-tarsal condylar fractures are considered fatigue injuries of subchondral bone (SCB) and calcified cartilage due to repetitive high loads in racehorses. In combination with adaptive changes in SCB in response to race training, the accumulation of SCB fatigue is likely to result in changes of joint surface mechanical properties. OBJECTIVES: To determine the spatial relationship and correlation of calcified articular surface biomechanical properties with SCB microstructure and training history in the distal palmar metacarpal condyle of Thoroughbred racehorses...

BACKGROUND: Dislocation of all 5 carpometacarpal (CMC) joints of a single hand is a rare injury. METHODS: The literature regarding CMC fracture-dislocations was reviewed and a case was presented. RESULTS: The relevant literature was consolidated to clinically relevant categories including 'Clinical Presentation and Diagnosis,' 'Management of CMC Fracture Dislocation and Hamate Fractures,' and 'Outcomes.' CONCLUSIONS: The mechanism associated with this injury is often high energy that causes multiple simultaneous life- or limb-threatening injuries that could distract the examiner from identifying this injury...

Rupture of the deep transverse metacarpal ligament (DTML) can result in pain, impaired grip strength, and undermine functional performance of the hand. We describe the case of a patient whose right hand came into contact with a boat propeller. He sustained a complete disruption of the DTML between the second and third ray in addition to soft tissue injury and open metacarpal fractures. Although other techniques describe a reconstruction of the DTML, our technique describes an adjunctive technique that strongly augments the A1 pulley reconstruction and nullifies the requirements of palmaris longus graft...

We present two cases of pathologic fractures extended to the metacarpal head related with enchondromas at the metacarpal neck treated by surgery. The timing of surgery varied between the two cases. The first was operated without delay, using tumor curettage and β-TCP (tricalcium phosphate) packing in the cavity, followed by internal fixation of the fracture using a screw and Kirshner wires. In the second case, tumor curettage and β-TCP packing was performed after fracture union. Favorable clinical outcomes were obtained for both cases...

BACKGROUND: We compared 3 surgical approaches to the MP joint: a dorsal extensor tendon-splitting approach, a dorsal extensor tendon-reflecting parasagittal approach, and the volar A1 pulley approach. We quantitatively compared each of these approaches by measuring the amount of articular cartilage exposed on the base of the proximal phalanx. We hypothesize that visualization of the articular cartilage of the proximal phalangeal base is enhanced with the volar approach. METHODS: The MP joints of the 32 available digits were randomly assigned to 1 of 3 surgical approaches: extensor tendon splitting (A), extensor tendon reflecting (B), or volar approach (C)...

INTRODUCTION: The treatment of the flexor tendon adhesions following phalanx and metacarpal fractures, in closed or open injuries, is a great challenge for the hand surgeon. The outcomes are often poor, because of the severity of the lesion and the aggressiveness of the surgical procedure of the secondary tenolysis. MATERIALS AND METHODS: The authors describe the technical findings and the results of a new mini-invasive tenolysis in order to treat the adhesions in zone 1 and 2 of the fingers, following phalangeal and metacarpal fractures...

BACKGROUND: During the surgery for a distal radius fracture, we encountered a large anomalous muscle lying across the distal radius. The muscle was identified as a flexor carpi radialis brevis muscle (FCRB), based on its location, function, and innervation. This experience led us to clarify its prevalence in living subjects and alert surgeons of its presence. METHODS: We reviewed wrist MRI scans of 515 hands of 379 patients with carpal tunnel syndrome (CTS). The prevalence of the FCRB was calculated...

A detailed histopathological study of the distal third metacarpal bone of Thoroughbred racehorses was undertaken to characterize lesions observed previously on magnetic resonance imaging (MRI). The bones were selected and grouped on the basis of MRI features. Representative sections in different planes were processed for histopathology. All lesions observed in the articular cartilage (AC) and subchondral bone (SCB) were recorded and graded with a scoring system, based partially on the Osteoarthritis Research Society International grading system...
