Isolated neuropathy of the cutaneous branch of the radial nerve is a rarely recognised condition. Five cases were described in 1932 by Wartenberg, who suggested the name cheiralgia paraesthetica. The condition has also been described as Wartenberg's disease. Twelve cases of isolated neuropathy of the cutaneous branch of the radial nerve are described, the literature is reviewed and the clinical picture outlined. In six of the cases the condition subsided without treatment, in two there was a good response to local injection of hydrocortisone, and in four cases a satisfactory result followed resection of the nerve. The course and distribution of the superficial branch of the radial nerve are described. The need to avoid the nerve during operations around the wrist is stressed.

Objective: The primary aim was to describe the epidemiology of the Holstein-Lewis humeral shaft fracture, its association with radial nerve palsy and the outcome regarding recovery from the radial nerve palsy and fracture healing. The secondary aim was to analyze the long-term functional outcome.

Setting: Six major hospitals in Stockholm County.

Design: Descriptive study. Retrospective assessment of radial nerve recovery and fracture healing. Prospective assessment of functional outcome.

Patients: All 27 patients with a 12A1.3 humeral shaft fracture according to the OTA classification satisfying the criteria of a Holstein-Lewis fracture in a population of 358 consecutive patients with 361 traumatic humeral shaft fractures.

Intervention: Nonoperative or operative treatment according to the decision of the attending orthopedic surgeon.

Main Outcome Measurements: Recovery of the radial nerve, fracture healing and functional outcome according to the Short Musculoskeletal Function Assessment (SMFA).

Results: The Holstein-Lewis humeral shaft fracture constituted 7.5% of all humeral shaft fractures and was associated with an increased risk of acute radial nerve palsy compared to other types of humeral shaft fractures, 22% versus 8% (p< 0.05). The fractures of six of the seven operatively treated patients healed after the primary surgical procedure while one fracture healed after revision surgery. The fractures of all patients treated nonoperatively healed without any further intervention. All six radial nerve palsies (two patients treated nonoperatively and four operatively) recovered. The functional outcome according to the SMFA was good with no differences between the nonoperatively and operatively treated patients: SMFA dysfunction index 7.6 and 9.7, respectively, and SMFA bother index 6.1 and 6.8, respectively.

Conclusion: The Holstein-Lewis humeral shaft fracture was associated with a significantly increased risk of acute radial nerve palsy. The overall outcome regarding fracture healing, radial nerve recovery, and function is excellent regardless of the primary treatment modality, i.e. operative or nonoperative treatment. The indication for primary operative intervention in this fracture type appears to be relative.

Aims

Arthroplasty is being increasingly used for the management of distal humeral fractures (DHFs) in elderly patients. Arthroplasty options include total elbow arthroplasty (TEA) and hemiarthroplasty (HA); both have unique complications and there is not yet a consensus on which implant is superior. This systematic review asked: in patients aged over 65 years with unreconstructable DHFs, what differences are there in outcomes, as measured by patient-reported outcome measures (PROMs), range of motion (ROM), and complications, between distal humeral HA and TEA?

Complications of distal radius fractures range from 20 to 30% and are consequence of injury or of treatment. Management of these complications must be individualised and the multitude of proposal treatments prove that this problem is controversial. Complications may involve soft tissue (tendon, nerve, arterial or fascial complication, reflex symphatetic distrophy) or bone and joint (malunion, nonunion, osteoarthritis). Tendon complications following distal radius fractures, range from minor adhesions to complete rupture. Peritendinous adhesions will become apparent after cast removal. Diagnosis is based on the limitation of the range of movement for individual fingers.This complication can be avoided with a proper cast technique allowing full range of motion to the digits. Treatment consists of rehabilitation techniques and only rarely, in severe cases, operative tenolysis may be a treatment of choice. Tendons may be entrapped either in the fracture site or in the distal radioulnar joint. Most common tendon entrapment are for extensor carpi ulnaris and extensor digiti minimi. If early recognition is made, open reduction with freeing the tendon must be the choice. Late diagnosis will require more complex tenolysis procedures. Tendon rupture may occur at the time of injury due to sharp fracture fragments. Diagnosis is based on identification of functional loss and, whenever possible, primary tendon suture is recommended. If the diagnosis is late the treatment is free tendon graft or tendon transfer. The late rupture of extensor pollicis longus is the most common possibility. Since it is not related with comminution or displacement of fracture it is possible that an ischemic mechanism is involved. Solutions are free tendon graft or the transfer of extensor indicis proprius. Direct tendon repair is not recommended after few weeks. Nerve complications. Careful neurological investigations demonstrated that nerve injuries associated with distal radius fractures are more common than it is believed. Median nerve is most frequently involved. Primary mechanisms of injury are: direct lesions due to fracture fragments, lesions related to forced manipulation and nonanatomical position of immobilization. Late injuries, occurring a long time after the fracture are more frequent and are related to carpal tunnel syndrome or paraneural adhesions. Carpal tunnel pressure could be measured and ethiologic factors must be identificated in order to establish the proper treatment, usually based on relise of carpal tunnel. Ulnar and radial neuropathy are less common and treatment may vary from cast removal to relise of Guyon’s canal. Vascular complications are uncommon, arise usually in relation with high energy trauma and the treatment is complex, involving different speciality surgeons. Some authors presented rare cases of entrapment of vasculare structures or radial artery pseudoaneurism after the use a volar plate. Compartment syndrome after distal radius fracture is rare and is likely to occur in young adults suffering a high energy trauma. Clinical diagnosis is based on the classical 5 “P’s” (pain, pallor, paresthesias, paralysis, and pulselessness) but treatment must start before all symptoms are present. Anytime when compartment syndrome is suspected, intracompartimental pressure must be measured. The treatment must start immediately and consist in removal of constrictive devices (bandage, cast) and fasciotomy. Indications for fasciotomy are intracompartmental pressure of 15–25mmHg in presence of clinical signs or over 25mmHg in absence of clinical signs. If there is doubt, it is better to perform an unnecessary fasciotomy than to wait until lesions becomes irreversible. Reflex sympathetic distrophy is described with many terms such as algodistrophy, cauzalgia, Sûdeck’s atrophy, shoulder-hand syndrome. Recently, the term complex regional pain syndrome was proposed to replace all the exiting synonyms. Despite many theories, the pathogeny of this disease is uncertain. The diagnosis is mainly clinical, based on presence of pain, trophic changes (atrophy, stiffness, edema) and functional impairment but plain x-ray demonstrating osteopenia and bone scintigraphy showing abnormal bone turnover may be helpful. Since the patogeny is unclear, the treatment is targeting the symptoms rather then the disease. Treatment must be individualized and may consist of: physical therapy of the hand, pain control with general or local drugs, corticosteroids, and symphatectomy. Prevention of reflex symphatetic dystrophy in the first days of a distal radial fracture is very important and include: prevention of the edema (elevation of the hand, early mobilization of fingers), decrease of pain, cast removal to relive pression, non-traumatic surgery. Malunion is the most common complication of distal radius fracture and it usually occurs after close treatment. The malalignament may be extraarticular or it may involve the joint (radiocarpal or distal radioulnar joint). Axial shortening and dorsal or radial malalignament are the most common. Clinical signs are wrist pain, loss of grip strength, limitation of wrist mobility. Osteoarthritis is likely to develop in both types of malunions. For extraarticular nonunions osteotomy is usually the treatment of choice. Many types of osteotomies have been proposed but the most commonly used are opening wedge osteotomy and Watson osteotomy. Intraarticular malunion is more difficult to treat and many surgical solutions have been proposed: intraarticular osteotomy, bone resections (styloid, anterior or posterior rim, radiolunate or radioscapholunate limited arthrodesis, proximal row carpectomy, wrist denervation, wrist arthroplasty, total wrist arthrodesis). Salvage procedures on the distal radioulnar joint may be resection of distal cubitus (Darrach) or Sauve-Kapandji technique. Nonunion is an extremely rare complication and is likely to occur in patients with multiple comorbid conditions such as diabetes, peripheral vascular disease or alcoholism. In most cases the initial treatment was close reduction and cast immobilization or external fixation. Diagnosis is based on the absence of radiographic signs of union at 6 months. Treatment must be individualized but basic options are reconstructive procedures or wrist arthrodesis. Reconstructive procedures consist of debridement of nonunion site, realignment with distractor, plate and screw fixation and iliac crest bone grafting. Since the bone is of poor-quality, new implants providing fixation in orthogonal planes may be useful. Usually, malalignement is present, so some authors recommend to take in to consideration the possibility to associate reconstructive procedures with additional techniques such as: dividing brachioradialis tendon, incision of the dorsal or volar joint capsule or Darrach operation in presence of severe shortening of the radius. Wrist arthrodesis should be chosen when the distal fragment has less then 5 millimeters of subchondral bone supporting the articular surface

Aims

The aims of this study were to validate the outcome of total elbow arthroplasty (TEA) in patients with rheumatoid arthritis (RA), and to identify factors that affect the outcome.

We retrospectively reviewed 89 consecutive patients (45 men and 44 women) with a mean age at the time of injury of 58 years (18 to 97) who had undergone external fixation after sustaining a unilateral fracture of the distal humerus. Our objectives were to determine the incidence of heterotopic ossification (HO); identify risk factors associated with the development of HO; and characterise the location, severity and resultant functional impairment attributable to the presence of HO.

HO was identified in 37 elbows (42%), mostly around the humerus and along the course of the medial collateral ligament. HO was hazy immature in five elbows (13.5%), mature discrete in 20 (54%), extensive mature in 10 (27%), and complete bone bridges were present in two elbows (5.5%). Mild functional impairment occurred in eight patients, moderate in 27 and severe in two. HO was associated with less extension (p = 0.032) and less overall flexion-to-extension movement (p = 0.022); the flexion-to-extension arc was < 100º in 21 elbows (57%) with HO compared with 18 elbows (35%) without HO (p = 0.03). HO was removed surgically in seven elbows.

The development of HO was significantly associated with sustaining a head injury (p = 0.015), delayed internal fixation (p = 0.027), the method of fracture fixation (p = 0.039) and the use of bone graft or substitute (p = 0.02).HO continues to be a substantial complication after internal fixation for distal humerus fractures.

We studied retrospectively the results of revision arthroplasty of the elbow using a linked Coonrad-Morrey implant in 23 patients (24 elbows) after a mean follow-up period of 55 months. According to the Mayo Elbow Performance Score, 19 elbows were satisfactory, nine were excellent and ten good. The median total score had improved from 35 points (20 to 75) before the primary arthroplasty to 85 points (40 to 100) at the latest follow-up. There was a marked relief of pain, but the range of movement showed no overall improvement. Two patients had a second revision because of infection and two for aseptic loosening. The estimated five-year survival rate of the prosthesis was 83.1% (95% confidence interval 61.1 to 93.3). Revision elbow arthroplasty using the Coonrad-Morrey implant provided satisfactory results but with complications occurring in 13 cases.
