REVIEW
Steven Regal, Aakash Chauhan, Peter Tang
Cortical bone grafting is commonly required in the finger, hand, and carpus when managing bony trauma. A donor site that can provide a small or large amount of cortical bone graft that is easily accessible and within the same surgical field would be the ideal donor site. In high-energy injuries, a long cortical graft may be needed to reconstruct massive bony defects. In low-energy injuries such as scaphoid nonunions in which a wedge graft is needed, a reliable and easily accessible source of bone grafting would be beneficial...

#2
REVIEW
David A Muzykewicz, Reid A Abrams
Anterior transhumeral radial nerve transposition has been described in the treatment of humeral shaft fracture to protect the nerve from implant irritation or callus entrapment. Transposing the radial nerve through a facilitating humeral defect also simplifies revision surgery should nonunion result. Here we describe a surgical technique for anterior transhumeral radial nerve transposition for complex humeral reconstruction when subsequent revision surgery is anticipated. Three cases are used for illustration: (1) revision of a total elbow arthroplasty with periprosthetic fracture; (2) revision of a total elbow arthroplasty after aseptic loosening from an allograft/prosthesis composite; and (3) septic humeral nonunion with substantial bone loss...

PURPOSE: In January 2006, the American College of Emergency Physicians released updated guidelines for air transfer. Digit amputation and near-amputation were no longer an indication for this costly service. We analyzed the effect of this update on the use of air transport and associated care outcomes for finger amputation patients and examined factors involved in providing follow-up care for these patients. METHODS: A retrospective chart review identified all patients treated for traumatic finger amputation between 1995 and 2012 at a major hand trauma referral center...

Avascular necrosis (AVN) of the capitate is a rare clinical entity for which a variety of treatment options have been described, ranging from immobilization to microvascular bone transfer. Outcomes following medial femoral condyle corticocancellous free flap reconstruction have not been reported for this specific pathology. We present the case of a 16-year-old girl with posttraumatic capitate AVN who was treated with curettage and medial femoral condyle corticocancellous vascularized bone grafting. At 18 months after surgery, the patient remains pain-free and had resumed all activities including lifeguarding by 6 months after surgery...

PURPOSE: Children with Hurler syndrome (HS) develop carpal tunnel syndrome (CTS) owing to glycosaminoglycan deposition secondary to enzyme deficiency. Advancement in the treatment of the underlying enzyme deficiency now commonly includes peritransplant intravenous enzyme replacement therapy (ERT). The primary objective of this study was to determine if the use of limited ERT in addition to hematopoietic stem cell transplantation (HCT) for the treatment of children with HS reduces the incidence of surgical intervention for CTS compared with a cohort of historical controls treated with HCT alone...

PURPOSE: Fractures of the base of the middle phalanx are particularly challenging. Dorsal fracture-subluxations/dislocations of the proximal interphalangeal (PIP) joint are relatively common, but the volar fracture-subluxation/dislocation, the so-called "central slip fracture," is quite rare. The current study presents our experience with surgically treated patients with central slip fracture subluxation/dislocation with a minimum of 1 year follow-up. We hypothesized that the majority of patients with a central slip fracture-subluxation/dislocation have poor outcomes...

PURPOSE: To determine whether there is a difference in the incidence of infection between exposed and buried K-wires when used to treat phalangeal, metacarpal, and distal radius fractures. METHODS: We conducted a retrospective review identifying all patients aged greater than 16 years who underwent fixation of phalangeal, metacarpal, or distal radius fractures with K-wires between 2007 and 2015. We recorded patient demographic data, fracture location, number of K-wires used, whether K-wires were buried or left exposed, and duration of K-wire placement...

PURPOSE: To investigate the effect of implant positioning on ulnohumeral contact using patient-specific distal humeral (DH) implants. METHODS: Seven reverse-engineered DH implants were manufactured based on computed tomography scans of their osseous geometry. Native ulnae were paired with corresponding native humeri and custom DH implants in a loading apparatus. The ulna was set at 90° of flexion and the humeral component (either native bone or reverse-engineered implant) was positioned from 5° varus to 5° valgus in 2...

Laura A Sonoda, Neil F Jones
Carpometacarpal joint arthritis of the thumb is a common problem. Mini suture suspensionplasty has been reported as a successful treatment option. We describe a case of a ruptured suture button suspensionplasty that caused pain and thumb metacarpal subluxation. To our knowledge, this is the first reported mechanical failure of a suture suspensionplasty. Surgeons should be aware of this potential complication when using this device to treat thumb carpometacarpal arthritis surgically.

PURPOSE: Radial head arthroplasty is indicated in displaced fractures in which comminution precludes successful internal fixation. Many types of radial head implants have been developed varying in material, methods of fixation, and degrees of modularity and geometry. The purpose of this study was to investigate the effect of radial head implant shape on radiocapitellar joint congruency. METHODS: Joint congruency was quantified in 7 cadaveric specimens employing a registration and inter-surface distance algorithm and 3-dimensional models obtained using computed tomography...

PURPOSE: The deep component of the distal radioulnar ligament provides translational stability and rotational guidance to the forearm. However, controversy exists regarding the importance of this structure as well as the nature of its attachment to the distal ulna. We aimed to evaluate the topographic anatomy of the distal ulna attachment of both the superficial and the deep components of the radioulnar ligament and to assess the relationship between its internal and its external morphometry...

REVIEW
Avi D Goodman, Christopher J Got, Arnold-Peter C Weiss
Crush injuries of the hand are a rare but devastating phenomenon, with historically poor outcomes. A compressive force, usually caused by a high-energy mechanism such as a motor vehicle or industrial accident, crushes and transiently increases the pressures within the hand. This force acts on the incompressible blood in the vasculature and leads to a dramatic rise in tissue pressures and damage to multiple tissue types, including bones, blood vessels, nerves, and soft tissues. A wide zone of injury results from a delayed inflammatory reaction involving the zone bordering the crushed cells, which may initially belie the severity of the injury...

REVIEW
Brooks W Ficke, Erin F Ransom, Jean E Oakes
Near-infrared vein visualization devices allow for noninvasive identification of superficial veins. During index finger pollicization, preservation of the dorsal veins is important for protecting blood outflow from the digit. Near-infrared vein visualization devices can be used to identify the location of the dorsal veins prior to skin incision, allowing increased confidence during dissection. We describe the use of this device to identify veins during index finger pollicization.

PURPOSE: No consensus has been reached on the most effective anatomic approach or fixation method for distal biceps repair. It is our hypothesis that, using a cortical biceps button through a 2-incision technique, the distal biceps can be safely and anatomically repaired. METHODS: A 2-incision biceps button distal biceps repair was completed on 10 fresh-frozen cadavers. The proximity of the guide pin to the critical structures of the forearm, including the posterior interosseous nerve and recurrent radial artery, was measured...
