Carpal fractures in athletes excluding the scaphoid

Return to Play After Hook of Hamate Fracture: A Systematic Review and Meta-Analysis

In athletes, a hook of hamate fracture is concerning in terms of time to return to sport and effect on performance upon return. This study aims to analyze the treatment of hook of hamate fractures in athletes to determine their rates of return to play, timelines of recovery, and performance level upon return to play. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to perform this analysis. The PubMed database was queried to perform the literature search. Data were pooled and analyzed. P values <.05 were considered significant. Data were analyzed using the Comprehensive Meta-Analysis software to determine heterogeneity. Twenty studies with 823 patients sustaining hook of hamate fractures that reported any competitive level of play were included in the analysis. Of the 823 patients, 778 (94.5%) were able to return to play with 91.2% (506/555) of patients demonstrating similar or improved performance. The mean time to return to play was 45 days (range: 21-168 days). Treatment included surgical excision for 787 patients (95.6%), open reduction and internal fixation for 18 patients (2.2%), stress reduction/casting for 13 patients (1.6%), and loss to follow-up or surgery refusal for 5 patients (0.6%). A very high number of athletes return to play following a hook of hamate fracture at the same or improved level of performance. In our study, the majority of injuries were treated with surgical excision of the fractured hook of hamate fragment. Most athletes returned to their sport at an average of 45 days.

Isolated Trapezoid Fracture in Adolescent Goalkeepers: A Scoping Review of the Literature and a Report of Two Cases

Purpose

Isolated trapezoid fractures are rare injuries, particularly among adolescents, constituting only 0.4% of all carpal bone fractures. This study aims to present two cases of isolated trapezoid fracture in adolescent goalkeepers and a scoping review of the literature to provide guidelines for the management of this injury.

Methods

Following PRISMA-ScR guidelines, a scoping review of reported cases was conducted. Two hundred and twenty articles were found using PubMed and Google Scholar. After full-text review, a total of 30 cases from 22 articles along with our 2 cases were analyzed based on demographics, injury mechanism, method/timing of diagnosis, prognosis, and time to recovery.

Results

Thirty-two reported cases of trapezoid fractures with a mean age of 26.7 years (75% male) were found, with pain as the most common presenting symptom. A majority (78%) had initial negative findings on radiography, and the diagnosis was primarily established through computed tomography (59%; n = 19) or magnetic resonance imaging (50%; n = 16). There was a substantial delay in diagnosis (mean 26 days), primarily because computed tomography/magnetic resonance imaging was frequently ordered late. The majority of cases (78%) were managed conservatively, with immobilization periods ranging from 4 to 12 weeks. The average duration for full recovery was 4.5 months, with operative management taking 7.3 months and conservative management taking 3.5 months.

Conclusion

Trapezoid fractures, though rare, are often not promptly diagnosed on initial plain radiographs, leading to a potential underreporting of cases. Because of the risk of complications associated with this type of injury, clinicians should maintain a high level of vigilance and consider trapezoid fracture as a possible differential diagnosis when presented with carpal pain, swelling, or limited movement, particularly after axial load incidents. Further research and guidelines are needed to enhance our understanding and management of this uncommon injury in the future.

Surgical treatment for the uncommon bi-articular fracture of trapezium: A case report

Trapezium fracture is a rare condition that goes undetected and exposes to long-term comorbidities: chronic pain and rhizartrosis. Our work aims to summarize the clinical presentation and improve leading to therapeutic guidelines which are not well established by reporting a case of ORIF with mini-screws for a displaced fracture of the body of the trapezium with a satisfactory outcome.

Excision of Hook of Hamate Fractures in Elite Baseball Players: Surgical Technique and Return to Play

Background:

Hook of hamate fractures are relatively common in baseball players, but the proper diagnosis and surgical technique can be challenging. Outcomes after surgical excision, as well as optimal surgical technique, in elite baseball players have not been clearly established.

Hypothesis:

Excision of hook of hamate fractures with a technique tailored to elite professional and collegiate baseball players will lead to high rates of return to play within a short time.

Study Design:

Case series; Level of evidence, 4.

Methods:

We reviewed the cases of 42 elite athletes who underwent surgical excision of 42 hook of hamate fractures at a single academic hand surgery practice from 2006 to 2020. The athletes competed at the professional (n = 20) or varsity collegiate (n = 22) baseball levels and were treated using the same surgical technique tailored toward the elite athlete. The clinical history, timing of surgery, complications, and time to return to play were recorded for each patient.

Results:

All 42 patients underwent an excision of their hook of hamate fracture at a mean of 7.2 weeks (range, 0.5-52 weeks) from the onset of symptoms. All but one patient were able to return to full preinjury level of baseball participation within 6 weeks from the date of surgery, with a mean return to sport of 5.4 weeks (range, 3-8 weeks). Two patients returned to the operating room—1 for scar tissue formation causing ulnar nerve compression and 1 for residual bone fragment causing pain and ulnar nerve compression.

Conclusion:

Surgical excision of hook of hamate fractures in elite baseball players showed a very high rate of return to play within 6 weeks. Meticulous adherence to the described surgical technique tailored to athletes optimizes clinical outcomes and avoids complications.

A Comparison of the Outcomes of Excision of the Fractured Hook of Hamate via a Carpal Tunnel Approach versus a Lateral Approach

Background: The excision of the hook of the hamate is an accepted modality for the treatment of hook of hamate fractures. Three surgical approaches to the hook of hamate have been described in literature. This includes two palmar approaches namely the Guyon canal approach and the carpal tunnel approach, and the lateral approach. The aim of this article is to compare the outcomes of the carpal tunnel approach and the lateral approach. Methods: Twenty-four patients with hook of hamate fractures were treated by excision of the hook of hamate. The hook of hamate was approached via the carpal tunnel in 15 patients and via the lateral approach in 9 patients. The outcomes with regard to duration of the surgery, complications such as pain, sensory disturbance and scar problems and time to return to sports were measured and analysed. Results: There were no significant differences in outcomes between the carpal tunnel and the lateral approach for excision of hook of hamate fractures. Conclusions: The outcomes of excision of the hook of hamate via the carpal tunnel approach and the lateral approach are similar. The decision to choose an approach should be based on the surgeon's familiarity with the approach. Future studies should include a comparison with the Guyon canal approach preferably in a homogenous group of patients. Level of Evidence: Level IV (Therapeutic).

Comminuted Trapezium Fracture: Case Presentation and Review of Surgical Fixation Techniques

We report a case of a 28-year-old male who sustained a comminuted trapezium fracture with carpometacarpal subluxation of the right hand. Treatment with internal fixation with a headless compression screw resulted in excellent outcomes.

Triquetral Fractures Overview

PURPOSE OF REVIEW

The triquetrum is the second most commonly fractured carpal bone, comprising 15-18% of all carpal bone fractures. This review summarizes the current knowledge of triquetral fractures, including the anatomy and pathophysiology, evaluation and diagnosis, treatment and management, post-treatment outcomes, and complications.

RECENT FINDINGS

Triquetral fractures are frequently caused by impaction of the ulnar wrist after a fall on an outstretched hand or by avulsion of attached ligaments. There are three main types of triquetral fractures: dorsal cortical fractures, triquetral body fractures, and volar cortical fractures. Dorsal cortical fractures are the most common and are usually benign, while volar cortical fractures are the least common and can be problematic. Nonsurgical management is indicated for most triquetral fractures, which usually results in good outcomes. Surgical treatment is indicated for fractures with significant displacement or evidence of instability. Complications of triquetral fractures include non-union, triangular fibrocartilage complex injury, and pisotriquetral arthritis. While less common than scaphoid fractures, triquetral fractures should remain in the differential diagnosis for patients with ulnar-sided wrist pain after falling on an outstretched hand. Most triquetral fractures can be treated with immobilization, though they should be thoroughly evaluated due to their potential to result in instability, loss of motion, and arthrosis. Further research is needed to determine the best method of surgical treatment.

Progression of Hamate Hook Stress Reactions in Elite Baseball Players

Background:

Hamate hook fractures can occur as a result of repetitive contact with the knob of the bat used in the sport of baseball. Hamate hook excision has resulted in excellent outcomes and return to sport (RTS) in elite baseball players. The ideal treatment for hamate stress response before the development of a fracture line is unknown.

Purpose:

To report the outcomes of elite baseball players with hamate bone edema.

Study Design:

Case series; Level of evidence, 4.

Methods:

We reviewed the medical records of all elite baseball players with hamate bone edema consistent with a stress response at 2 institutions. Players were eligible for inclusion if they played collegiate or professional baseball at the time of initial injury, had magnetic resonance imaging (MRI) showing hamate bone edema, and had no radiographic evidence of acute fracture lines at initial presentation.

Results:

A total of 4 players with a mean age of 22.8 years were included. All injuries occurred in the nondominant hand. All athletes had normal initial wrist radiographs and MRI showing hamate edema but no fracture line. Patients returned to play as tolerated and developed an acute injury at an average of 25.8 days (range, 10-56 days) from the initial presentation. Repeat radiographs demonstrated acute hamate hook fractures in all 4 (100%) athletes. All 4 athletes underwent hamate hook excision. There were no postoperative complications. All athletes returned to sport at their previous level of competition at a mean of 5.3 weeks (range, 3.6-7.3 weeks).

Conclusion:

There is a high rate of hamate bone edema progression to acute hamate hook fracture in elite baseball players, with 100% RTS at preinjury level after hamate hook excision. We therefore recommend against prolonged rest. Continuation of play with hamate bone edema followed by hamate hook excision for acute fracture limits the time missed and obtains a faster RTS in elite baseball players.

Imaging of the Hand and Wrist

Imaging plays a key role in the evaluation and treatment planning of hand and wrist injuries in athletes. Depending on the suspected injury, a combination of conventional radiographs, computed tomography, magnetic resonance imaging, magnetic resonance arthrography, and/or ultrasound may be indicated. This article reviews the strengths and limitations of these imaging modalities and how they can be utilized in commonly encountered clinical questions.

Trapezium fracture: a common clinical mimic of scaphoid fracture

PURPOSE

Fractures of the trapezium are rarely diagnosed on plain radiographs after acute wrist trauma. High-resolution cross-sectional imaging identifies fractures of the trapezium as the most common radiographically occult carpal bone fracture. We review the fracture frequency, mechanisms and patterns of trapezium fractures.

METHODS

Cone beam CT was performed in patients with suspected radiographically occult radiocarpal fracture following acute injury. The frequency of carpal bone fractures was assessed and compared.

RESULTS

Ninety-three radiographically occult wrist fractures were identified in 166 patients with acute trauma and negative radiographs. The trapezium was the most frequently fractured carpal bone, making up 20.4% of wrist fractures. Seventy-nine percent of trapezium fractures involved the volar ridge. The scaphoid was the clinically suspected fractured bone at initial assessment in 84% of patients with trapezium fractures.

CONCLUSION

Fractures of the trapezium in acute wrist trauma are much more common than described in the literature. If initial radiographs are negative, a fracture of the trapezium is more likely to be present than one of the scaphoid, despite high levels of clinical suspicion for scaphoid injuries. Awareness of the types and mechanisms of trapezium fracture is important. Cross-sectional imaging should be considered in all cases of post-traumatic wrist pain with negative radiographs.

Treatment of Acute Carpal Bone Fractures

Carpal bone fractures are common hand fractures that can be complicated by concomitant damage to surrounding structures, chronic comorbidities, or delays in diagnosis. This article provides an overview of wrist anatomy, an expedited review of the athlete's presenting condition, and a systematic approach to the evaluation of the wrist. Recommended treatment plans are based on a review of the literature and an evidence-based approach to imaging studies. It is imperative that sports medicine providers be aware of current literature for carpal bone fractures and collaborate with other medical subspecialties and the athlete to provide recommendations for a safe return to play.

Intra-articular Fracture of the Distal part of the Triquetrum within the Pisotriquetral Joint: Case Report and Review of Literature

Background

Intra-articular fractures of the distal part of the triquetrum within the pisotriquetral joint are uncommon, and can be associated with tears of the dorsal carpal ligaments, pisiform subluxation and/or FCU dislocation. Their diagnosis is difficult and requires a high clinical suspicion and a proper radiological examination including oblique wrist x-rays, computed tomography and MRI scan. These fractures can be delayed diagnosed due to late presentation thus leading to painful nonunion, persistent instability and late pisotriquetral arthritis.

Case Report

We present a case of a 40-year-old male who complained about ulnarsided wrist pain after a fall on his extended wrist during bicycling. The diagnosis of triquetrum fracture was suspected on clinical examination and confirmed using standard and oblique radiographs and CT scan evaluation. He was immobilized in a short-arm cast for 6 weeks followed by a progressive return to wrist motion and subsequent strengthening for another 5 weeks. He reported complete resolution of pain and excellent wrist motion and function one year after the injury, demonstrating a Mayo score of 100.

Conclusion

Isolated intra-articular fractures of the triquetrum within the pisotriquetral joint are rare injuries and may constitute a subcategory of body fractures other than the dorsal cortical (chip), main body and volar lip avulsion fractures. Early clinical suspicion and proper imagine can lead to a successful outcome.

Hamulus Stress Fracture in a Batsman: An Unusual Injury in Cricket - A Case report and Review of Literature

Introduction:

Hamulus fractures are uncommon injuries constituting 2-4% of carpal fractures and are usually reported in athletes. Stress fractures of hamulus are even rarer and very few cases have been reported till date. In this case report, we present the first documented case of stress fracture of hamulus in a cricket batsman and review the existing literature on hamulus fractures, both acute and stress fractures, in sportspersons in general.

Case Report:

A 23-year-old, right-handed, cricket batsman presented with pain in the hypothenar region of his left hand of 7 weeks duration. The pain typically worsened during batting, and he had difficulty in gripping the bat. Plain radiographs were largely inconclusive; magnetic resonance images, however, demonstrated a stress fracture of the hamate hook. The patient was put on conservative management, and his bat grip was modified. He recovered completely within 12 weeks and went back to playing professional cricket.

Conclusions:

Hamulus stress fractures should be considered in cricketers presenting with chronic, non-traumatic, and ulnar-sided hand pain. The nonleading hand is more likely to be involved in a batter, as seen in other sports with a double haSnd grip. Nonoperative treatment, change of grip and adequate rehabilitation give good outcomes in most cases.

Return to Play and Complications After Hook of the Hamate Fracture Surgery

PURPOSE

The purpose of this study was to evaluate the efficacy of hook of the hamate excision for fracture in a large cohort of patients to better understand recovery time and complications.

METHODS

We retrospectively reviewed the medical records of patients treated with surgical excision for hook of the hamate fractures at 2 different centers. We collected information on demographics, clinical presentation, and postoperative complications. Continuous outcome variables included time to surgery, return to play, and return to activity.

RESULTS

Our cohort of 81 patients had a median age of 22 years and was composed of 74 athletes including 57 baseball players and 8 golfers. The median time to return to play was 6 weeks (range, 1-36 weeks) after surgery; 11 patients (14%) had a return at 12 weeks or longer. Seventy-eight patients returned to preinjury activity levels. Twelve patients with a full recovery continued to experience some level of intermittent, nonspecific pain in the affected hand, although this was not severe enough to require additional treatment. We observed a 25% incidence of postoperative complications with the majority consisting of transient ulnar nerve dysfunction. Complications were more common among nonathletes, those presenting with nonunions, and those experiencing longer intervals between injury and surgery.

CONCLUSIONS

In most cases, surgical excision as treatment for hook of the hamate fractures is safe and allows a relatively rapid return to play. However, we found a higher incidence of complications, including transient ulnar nerve dysfunction, than has been previously reported. In addition, there is a group of patients with delayed return to play and continued discomfort after surgery. These findings should inform the discussion with surgical candidates.

Acute hand injuries in athletes

Hand and wrist injuries in athletes are common, representing between 3 and 25% of all sports injuries. As many as a quarter of all sports injuries involve the hand or wrist. We review the recent literature regarding acute hand injuries in athletes based on the structures involved - bone, muscle/tendon, ligament, and neurovascular - including diagnosis and pathophysiology of these injuries, focusing on athlete-specific facets of treatment, and when available, opinions on return to play.

Uncommon carpal fractures

Fractures of the hand are frequently encountered with injuries to the phalanges and metacarpals comprising the vast majority. Fractures of the carpal bones excluding the scaphoid, however, are fairly uncommon. Despite the rarity of fractures of the remaining seven carpal bones, they can cause a disproportionate amount of morbidity from missed diagnosis due to their subtlety as well as their frequent association with significant ligamentous disruption or even other carpal bone fractures. Delayed diagnosis can result in inadequate fracture care, which places the wrist at risk of disabling sequelae. This review focuses on the current concepts of pathophysiology, diagnosis, and treatment of carpal fractures other than the scaphoid.

Carpal fractures other than scaphoid

Carpal fractures are uncommon, but if missed, can lead to morbidity and loss of function, especially in an athlete. Early diagnosis through physical examination, plain radiographs, and possibly advanced imaging is paramount. Treatment is specific to each fracture type, and return to play varies with each clinical scenario. This article organizes current knowledge of these potentially difficult fractures with a table of diagnoses and treatment guidelines.

Outcomes of hook of hamate fracture excision in high-level amateur athletes

PURPOSE

To determine the overall long-term postoperative clinical and functional results of high-level amateur athletes after hook of hamate excision, based on complications; return to sport; Disabilities of the Arm, Shoulder, and Hand (DASH) score; and a self-reported questionnaire.

METHODS

We evaluated 11 patients representing 12 cases of hook of hamate excision. All patients were high-level amateur athletes (rising collegiate or collegiate level). We performed a retrospective chart review to elicit information pertaining to the patient's injury. We assessed long-term postoperative outcomes with a self-reported questionnaire, the DASH form, and the DASH Sport/Performing Arts Module form.

RESULTS

All patients successfully returned to full participation in their respective sports an average of 6 weeks after surgery. The average postoperative DASH score was less than 1, and all patients scored a 0 on the DASH Sports form. There was a significant improvement in preoperative pain after surgical intervention. There was no significant difference between preinjury and postoperative performance scores. Finally, every patient was very satisfied with the surgical outcome. There was only 1 postoperative complication in which a patient developed transient ulnar nerve paresthesias, which completely resolved by 6 weeks after surgery.

CONCLUSIONS

Surgical excision of hook of hamate fractures in high-level amateur athletes allows for successful return to sports participation at preinjury performance levels, achievement of normal function as measured by validated objective outcome measures, significant reduction in pain, and high overall patient satisfaction. We consider surgical excision to be a safe and effective technique to restore normal function and hasten return to play for high-level amateur athletes.

The emergent evaluation and treatment of hand and wrist injuries

The anatomy of the hand is complex, which allows for the dexterity, strength, and adaptability of the most functional aspect of the musculoskeletal system. The evaluation and management of injuries to this area can be time consuming and pose a significant medicolegal risk to the emergency physician. Improperly diagnosed and managed injuries can lead to chronic pain, inability to perform activities of daily living, and even seemingly minor injuries can lead to missed work causing a significant cost to the individual and society. The purpose of this article is to review injuries to the hand and wrist and discuss diagnostic studies and treatment plans that the emergency physician can use to treat patients effectively and minimize their exposure to risk.
